Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

When describing the embodiments of the present invention, some concepts used in the following description are first explained.

1. New radio (NR) physical broadcast channel (Physical Broadcast Channel, PBCH)

As shown in Figure 1 (wherein, the horizontal filled box in Figure 1 represents the frequency domain position for transmitting NR-PSS, the oblique filled box represents the frequency domain location for transmitting NR-PBCH and PBCH-DMRS, and the grid filled box represents the transmission The frequency domain position of NR-SSS), the NR synchronization signal block (Synchronization Signal Block, SSB) structure is as follows:

A11. Primary Synchronization Signal (PSS): an m-sequence with a length of 127, located in 1st Orthogonal Frequency Division Multiplex (OFDM), and occupying subcarriers ^56-182 .

A12. Secondary Synchronization Signal (Secondary Synchronization Signal, SSS): an m-sequence with a length of 127, located in the ^3rd OFDM, and occupying subcarriers 56-182.

A13, PBCH: the bandwidth is 20RB, occupying 3 OFDM symbols, including the ^2nd symbol, the ^4nd symbol, and the 4 RBs on both sides of the ^3rd symbol. Among them, the PBCH payload (Payload) is 32 bits, and the Cyclic Redundancy Check (CRC) attachment is 24 bits. A total of 56 bits of information are transmitted, occupying 432 resource elements (Resource Element, RE) and adopting quadrature phase shift keying ( Quadrature (Quaternary) Phase Shift Keying, QPSK)

A14. PBCH-DMRS: PBCH demodulation pilots are mapped to PBCH with a frequency domain density of 1/4 (ie, each PBCH occupies 3 subcarriers).

A15. Physical Cell Identifier (PCI): it consists of:

共1008个PCI。in,

A total of 1008 PCIs.

The SSB period can be configured as {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}, and the PBCH transmission time interval (Transmission Time Interval, TTI) is fixed at 80ms.

Each cycle may contain one or more SSBs, and the SSBs in the same cycle are sent within a 5ms window. These SS blocks form a synchronization signal collision set (SS burst set). The maximum number of SS blocks contained in an SS burst set is related to the carrier frequency, as shown in Figure 2:

A21. When the frequency is less than 3GHz, a SS burst set can contain up to 4 SS blocks; at this time, the SSBindex needs 2 bits and is carried in the DMRS.

A22. When the carrier frequency range is from 3GHz to 6GHz, a SS burst set can contain up to 8 SSblocks; at this time, the SSB index needs 3 bits and is carried in the DMRS.

A23. When the carrier frequency ranges from 6GHz to 52.6GHz, a SS burst set can contain up to 64 SS blocks; at this time, the SSB index needs 6 bits, and the 3-bit Least Significant Bit (LSB) is carried in the DMRS, and the 3LSB carried in PBCH.

When the SSB period is not known, the user assumes that the period is 20ms, and the SSBs with the same index in different periods (20ms) are quasi-co-located (QCL). For multiple SSBs of QCL, users can combine them to improve the decoding success rate.

Among them, when two broadcast channels are described as QCL, it refers to their Doppler spread (Doppler spread), Doppler shift (Doppler shift), average gain (average gain), average delay (average delay), time At least one of delay spread and spatial Rx parameters is the same, or quasi-co-location can be defined as: User Equipment (User Equipment, UE, also called terminal) can assume that in the QCL The two broadcast channels are consistent with respect to Doppler spread, Doppler shift, average gain, average delay, and delay spread.

2. Part of the process in the NR Uu PBCH generation method is as follows:

S11, the high layer generates 24bit;

S12, the physical layer generates 8 bits: mainly timing-related information that may change within a TTI80ms, for example, 1-4LSB system frame number (System Frame Number, SFN), 3-bit most significant bit of SSB index (MostSignificant Bit, MSB ) (for low frequencies, the 3 bits corresponding to the 3bit MSB of the SSB index at high frequencies are not used to carry the SSB index, but are still generated by the physical layer) and half frame indicator (HFI);

S13, concatenate the generated bits of the upper layer and the physical layer into a 32bit payload;

S131. Perform layer 1 scrambling: do not scramble some bits in the physical layer generated bits (ie, 3MSB SSB index of PBCH (or 3 bits corresponding to low frequency), HFI, and 2/3LSB SFN), and scramble other bits of the PBCH payload ;

a1. In the first layer scrambling, the scrambling sequence is related to the 2/3LSB SFN carried in the PCI and PBCH;

a2. Since the 2/3LSB SFN is not scrambled for the first time, the above 2/3LSBSFN can be determined after PBCH decoding to determine the first layer scrambling code, which can be directly descrambled without multiple assumptions and attempts, reducing complexity ;

S132, generate a CRC, and perform channel coding on the PBCH payload

a1. The basic idea of the first layer scrambling is: do not scramble the bit parts with different contents of the two SSBs that can be combined, and scramble the parts with the same contents of the two SSBs that can be combined; The bit parts with different PBCH contents of different SSBs in the TTI are not scrambled, and the bit parts with the same content are scrambled

a2. Since the above-mentioned time-related bits are not scrambled for the first time, the complexity of descrambling and the complexity of blind detection can be reduced.

S133. Perform layer 2 scrambling: collectively scrambling the channel-coded bits

a1. In the second layer scrambling, the scrambling sequences corresponding to different SSBs are only related to the SSB index and/or HFI carried in the PCI and DMRS;

a2. Therefore, when the user performs the second descrambling, the second-layer scrambling sequence can be directly derived according to the relevant information obtained in the DMRS and synchronization signal detection process, without multiple assumptions and attempts, and the complexity is reduced.

S14, QPSK modulation, resource mapping, etc.

Therefore, the two-layer scrambling design ensures that the user can solve the PBCH in a short time with low complexity.

3. Physical Sidelink Broadcast Channel (PSBCH) in Long Term Evolution (LTE) Vehicle-to-Everything (V2X)

It should be noted that the direct communication link (Sidelink, SL) may also be referred to as side link/secondary link/side link/side link.

There are two Primary Sidelink Synchronization Signal (PSSS) symbols and two Secondary Sidelink Synchronization Signal (SSSS) symbols in a subframe in LTE V2X, the ID of the PSSS and the SSSS sequence The ID of the joint determines a SLID (Sidelink ID). In addition, there are three symbols carrying demodulation reference signals (Demodulation Reference Signal, DMRS), six symbols carrying PSBCH, only the DMRS sequence on the symbol where the DMRS is located will not be multiplexed with the PSBCH, and the specific format is shown in FIG. 3 .

4. Sidelink SSB

At present, in the case of normal cyclic prefix (NCP), the design of S-SSB (sidelink-Synchronization Signal Block) in NR sidelink is tentatively set as follows (subsequent modifications may be made), NR S-SSB period is 160ms, each period The number of S-SSBs sent within is shown in the following conclusions. It can be seen that the period, format of S-SSB, the number of S-SSB and NR SSB are very different.

A31. The structure of the NR S-SSB of NCP is shown in FIG. 4 . For the case of ECP, except that the number of PSBCH symbols after S-SSS is only 6, others are the same as those in FIG. 4 .

A32. The S-SSB period of all SCSs supports 160ms;

A33. The number of S-SSB transmissions in an S-SSB period can be (pre)configured;

For Frequency Range 1 (FR1):

When the subcarrier spacing is 15kHz, the number of transmissions can be {1,[2]};

When the subcarrier spacing is 30kHz, the number of transmissions can be {1,2,[4]};

When the subcarrier spacing is 60 kHz, the number of transmissions can be {1, 2, 4, [8]}.

For Frequency Range 2 (FR2):

When the subcarrier spacing is 60kHz, the number of transmissions can be {1, 2, 4, 8, 16, 32};

When the subcarrier spacing is 120kHz, the number of transmissions can be {1, 2, 4, 8, 16, 32, 64}.

In addition to NR sidelink, other sidelink-related technologies, such as Network Control Interactive Service (NCIS), may also require the design of sidelink broadcast channels, sidelink primary synchronization signals, sidelink secondary synchronization signals, and sidelink DMRS. The relative relationship of the signals may be different or the same as the NR S-SSB described above. In addition, other technologies, such as NR unlicense (NRU) or Internet of Things (IOT), may also need to design broadcast channels, and in these technologies, the broadcast channel or the transmission mode, period, TTI of the signal block in which the broadcast channel is located and structure may be different from NR SSB.

It should be noted that the LSB and the MSB are respectively defined as the least significant bit and the most significant bit. Taking SSB index=8 as an example, assuming that 6 bits are used to indicate the SSB index, then the binary of the SSB index is written as 001000, then 3MSB is the 3 bits from the left, which is 001; 3LSB is the 3 bits from the right, which is 000 . In addition, due to different coding habits and modes, the left and right order, LSB and MSB may be reversed from the above examples, or there may be different definitions in different programs, which are not excluded in the embodiments of the present invention.

The present invention aims at generating, scrambling and transmitting broadcast channels of other technologies in the communication technologies other than the NR Uu interface, which cannot follow the NR SSB generation, scrambling and transmission procedures, resulting in incomplete network communication procedures and inability to ensure communication reliability. The problem is to provide an information sending and receiving method, a control node and a terminal.

As shown in FIG. 5 , an embodiment of the present invention provides a method for sending information, which is applied to a sending end, including:

Step 501, generating first information;

It should be noted that the generation method of the first information includes one of the following:

B11. Generated by the physical layer;

In this case, it means that all bits in the first information are generated by the physical layer of the transmitting end.

B12, generated by high-level;

In this case, it means that all the bits in the first information are generated by the upper layer of the transmitting end.

B13. Part of the information is generated by the physical layer and part of the information is generated by the higher layer;

In this case, it means that some bits in the first information are generated by the upper layer of the transmitting end, and some bits in the first information are generated by the physical layer of the transmitting end.

Step 502, sending the first information to a receiver through a broadcast channel;

It should be noted that the generated first information is the information contained in the broadcast channel, therefore, the sender needs to send the broadcast channel carrying the first information to the receiver.

The sending end mentioned in the embodiment of the present invention may be a terminal in direct communication, or may be a network side device, for example, an access network node in NR unauthorized.

It should be noted that, because the physical layer can generate information of some or all bits in the first information, when the first target information in the first information (the first target information includes at least part of the first information) When generated by the physical layer, at least some of the bits in the first target information are determined according to at least one of the following parameters:

B21. Quasi-co-location parameters;

B22. A repetition parameter indicating a repetition relationship between broadcast channels;

B23. Transmission time interval (TTI) of the broadcast channel;

B24. Period of broadcast channel;

B25. The index of the target parameter;

It should be noted that the target parameter includes at least one of the following:

B251, broadcast channel;

B252, the signal block where the broadcast channel is located;

For example, the index of the signal block where the broadcast channel is located may be an S-SSB index, a DRS index, or the like.

B253. The time domain resource where the broadcast channel is located;

For example, the index of the time domain resource where the broadcast channel is located may be a slot index, an HFI, or the like.

B26, the first parameter (the first parameter is subsequently represented by K in the embodiment of the present invention);

It should be noted that the first parameter is determined by the control node configuration, pre-configuration, protocol agreement, other terminal instructions except the sending end, or the sending end; specifically, the control node may be a network-side device, or may be a For direct communication equipment, for example, a terminal for direct communication, the control node may also be a roadside terminal.

Further, the method for determining the first parameter includes the following:

B261, determine the ratio of the period of the broadcast channel to the TTI of the broadcast channel as the first parameter;

B262, determine the ratio of the interval time of the broadcast channel to the TTI of the broadcast channel as the first parameter;

It should be noted here that the interval time of the broadcast channel may be the interval frame number of the broadcast channel, for example, the interval between two broadcast channels is 2 frames.

B263. Determine the ratio of the interval time of the broadcast channel to the period of the broadcast channel as the first parameter.

B27. Number of broadcast channels.

It should be noted that the first information may include bits related to the frame number (that is, the system frame number), and/or include an index (it should be noted that the indexes mentioned in the embodiments of the present invention all refer to the above-mentioned B25 at least one of) related bits, and when at least two broadcast channels are quasi-co-located (QCL), repeated, or at least partially the same, the frame number and/or index will cause the physical layer and the higher layer division. The following describes the composition of the first information from the perspective of frame number and index. Before the description, the situation that at least two broadcast channels are quasi-co-located or may be repeated is introduced as follows.

Assuming that the content of the broadcast channel is X bits (excluding CRC), that is, the above-mentioned first information is X bits, when the broadcast channels on different resources (or broadcast channels in different signal blocks including the broadcast channel, such as different synchronization A signal block or a broadcast channel in a Discovery Reference Signal (DRS)) is jointly detectable (for example, when different signal blocks or broadcast channels satisfy at least one of: QCL, repetition, at least some of the specific contents are the same, etc.) , it is considered that joint detection can be performed), the receiver side can combine or jointly detect these broadcast channels, thereby improving the decoding success rate of broadcast channel content. There are three possible situations:

Case 1. At least two broadcast channels in different periods are QCL, repeating or at least partially identical in specific content

Assuming that the period of the broadcast channel (or the signal block where the broadcast channel is located) is P, the TTI of the broadcast channel is T, and at least two broadcast channels located in different periods within the same TTI are QCL, repeated or at least partially identical in specific content , as shown in Figure 6, where T=P×K.

Case 2. At least two broadcast channels located in different frames within the same period or within the same TTI are QCL, repeating or at least partially identical in specific content 1. Assume that the period of the broadcast channel (or the signal block where the broadcast channel is located) is T, The positions of the m broadcast channels (or the signal blocks where the broadcast channels are located) are distributed in multiple frames in the period (one or more broadcast channels or signal blocks may exist in a frame). It is assumed that there may exist every P frames. For the broadcast channel (or the signal block where the broadcast channel is located), at least two broadcast channels located in different frames are QCL, repeat or at least partially have the same specific content, specifically, T=P×K. For example, as shown in Figure 7, there is 1 broadcast channel in each frame, and the broadcast channels between different frames are QCL, repeated, or at least partially the same in specific content; for example, as shown in Figure 8, there are multiple broadcast channels in each frame , the broadcast channel QCL, repetition or at least part of the specific content are the same between different frames; specifically, T=P×K.

It should be noted that, in this case, there may be further cases where there are broadcast channels in multiple periods within a TTI, and broadcast channels with the same index in different periods can be combined, for example, broadcast channels with the same index QCL is the same, repeated or at least partially the same specific content, and broadcast channels with different indexes in different periods cannot be combined, for example, the QCL is different or not repeated or the specific content is different; The broadcast channels with the same result after calculation (such as modulo or division with a specific value) can be combined. For example, at this time, these broadcast channels have the same QCL, duplicate or at least part of the same specific content, and the broadcast channels during the period cannot be combined. , for example, the QCLs of these broadcast channels are different or not repeated or the specific content is different.

It should also be noted that, in this case, there may be a further possibility that there are broadcast channels in multiple frames in one cycle, and there are multiple broadcast channels in one frame, and broadcast channels with the same index between different frames are possible. Combined, for example, the QCL is the same, repeated or at least partially the same specific content; broadcast channels with different indices between different frames cannot be combined, for example, the QCL is different, does not repeat or the specific content is different, as shown in Figure 9, different frames The broadcast channels can be combined; or the broadcast channels of any index in the frame or the broadcast channels with the same index after specific calculation (such as modulo or division with a specific value) can be combined, for example, the QCL is the same and repeated Or at least part of the specific content is the same, as shown in FIG. 10 , the same broadcast channel in the same frame can be combined; the intra-frame indices cannot be combined, for example, the QCL is different, the specific content is not repeated, or the specific content is different.

It should also be noted that, in this case, there may be further cases that there are multiple periods in one TTI, multiple frames exist in each period, and broadcast channels exist in multiple frames, and there are multiple broadcast channels in one frame. At this time, the relationship of the broadcast channel may be a combination of the above two situations. For example, in different periods of the same TTI, broadcast channels in the same frame relative to the starting point of their respective periods can be combined if the index is the same, the index mod M1 is the same, or the index/M2 is the same, for example, the QCL is the same, repeated or At least some of the specific content is the same. Specifically, for example, the broadcast channel with the same index, the same index mod M1 or the same index/M2 in the first frame in cycle 1 and the first frame in cycle 2 is QCL; wherein, M1 and M2 are respectively quasi-co-location parameters , one of a repetition parameter and a quasi-co-location parameter of the repetition relationship between broadcast channels, and a common multiple of a repetition parameter indicating the repetition relationship between broadcast channels.

Case 3: There are multiple broadcast channels (or signal blocks where broadcast channels are located) in the same frame, and at least two of these broadcast channels (or signal blocks where broadcast channels are located) are QCL, repeated, or at least partially specific 1. Suppose the period of the broadcast channel is P (or the period of the signal block containing the broadcast channel is P), the TTI of the broadcast channel is T, and m broadcast channels are distributed in a certain frame of each period. At least two broadcast channels within a frame are QCL, repetitive, or at least partially identical in specific content, as shown in FIG. 11 .

2. Assuming that the period of the broadcast channel is T (or the period of the signal block containing the broadcast channel is T), m broadcast channels are distributed in multiple frames of each period, and the distance between the frames containing the broadcast channel is P frame, assuming that at least two broadcast channels within the same frame containing broadcast channels are QCL, duplicated, or at least partially identical in specific content, as shown in Figure 12, three broadcast channels within the same frame are QCL, duplicated, or at least partially identical The specific content is the same.

1. The influence of frame number on physical layer and high-level division

1. In the case where at least two broadcast channels located between different frames are QCL, duplicate or at least partially identical

It should be noted that this situation is mainly aimed at the above-mentioned situations 1 and 2. In this case, the broadcast channel is QCL, and the distance between two frames with the same repeating or at least part of the specific content is P frames. .

Specifically, the second target information in the first information is generated by the physical layer, and the second target information includes at least part of the bits in the first information.

That is to say, in this case, the physical layer may generate some bits or all bits in the first information.

It should be noted that, in this case, the value of the number of bits of the second target information satisfies: greater than or equal to N and a multiple of 8;

即N为log₂(P)向上取整得到的整数；或者

即N为log₂(P)向下取整得到的整数；P为至少两个广播信道(这里需要说明的是，至少两个广播信道为QCL、重复或至少部分特定内容相同的广播信道)所在的帧之间的间隔时间，可选地，该间隔时间可以为间隔帧数。in,

That is, N is an integer obtained by rounding up log ₂ (P); or

That is, N is the integer obtained by rounding down log ₂ (P); P is the location of at least two broadcast channels (it should be noted here that at least two broadcast channels are QCL, repeat or at least some of the broadcast channels with the same specific content) The interval time between the frames, optionally, the interval time can be the number of interval frames.

Further, the second target information contains at least X bits of information of the frame number, that is to say, the information generated by the physical layer contains at least X bits of information of the frame number.

Specifically, the way of determining X includes one of the following:

B31, the X bits are the N+1th to N+Yth bits of the frame number;

或者

P为至少两个广播信道所在的帧之间的间隔时间，

即Y为log₂(K)向上取整得到的整数；或者

即Y为log₂(K)向下取整得到的整数；K为第一参数。specifically,

or

P is the interval time between frames where at least two broadcast channels are located,

That is, Y is an integer obtained by rounding up log ₂ (K); or

That is, Y is an integer obtained by rounding down log ₂ (K); K is the first parameter.

It should be noted here that since both Y and N are positive integers, X is also a positive integer.

B32, X bits are N+Y bits of the frame number;

It should be noted that in this case, the X bits should be at least N+Y bits of the frame number, and X is a positive integer; that is, when N+Y is 3, X should be greater than or An integer equal to 3.

It should also be noted that, in this case, the transmitting end scrambles the second target information before channel coding the second target information. It should be noted that at this time, the second target information is scrambled. The scrambling performed can be viewed as layer 1 scrambling.

Specifically, the value of X is 4, 6 or 10.

Specifically, the implementation manner of scrambling the second target information is:

Do not scramble at least some bits in the X bits of information in the second target information, or, use the scrambling sequence or scrambling when scrambling at least some bits in the X bits of information bit is 0.

An example of the above situation is as follows:

Example 1. If the broadcast channel TTI is 640ms and the broadcast channel period P=160ms, it is assumed that K=T/P=4. It is assumed that at least two broadcast channels in different periods are QCL, repeating, or at least partially identical in specific content. Then Y=log ₂ (K)=2, N=log ₂ (P/10)=4, N+Y=6; at this time, the broadcast channel content generation scheme includes:

The bits generated by the physical layer need to contain at least X bits of the frame number.

Optionally, the X bits correspond to the 5th and 6th bits of the frame number;

Optionally, the bits generated by the physical layer may also include the lowest six bits of the frame number; or,

the lowest seven digits; or,

the lowest eight digits; or,

If the number of bits generated by the physical layer is greater than 8, it may contain all ten bits of the frame number.

It should also be noted that, in addition to the above frame number information, the information generated by the physical layer may further include other information, such as HFI.

Optionally, when the X bits correspond to the 5th and 6th bits of the frame number, the transmitting end does not scramble the 5th and 6th least significant frame numbers when performing the first layer scrambling.

Example 2. If the broadcast channel TTI is 160ms or the broadcast channel period T=160ms, and it is assumed that a TTI with a length of 160ms or at least two broadcast channels located in different frames within the period are QCL, repeating or at least partially identical in specific content, and The time interval between the frames in which these broadcast channels are located is P. Let P=40ms, let K=T/P=4. Then Y=log ₂ (K)=2, N=log ₂ (P/10)=2, N+Y=4; at this time, the broadcast channel content generation scheme includes:

The bits generated by the physical layer need to contain at least X bits of the frame number.

Optionally, the X bits correspond to the 3rd and 4th bits of the frame number;

Optionally, the bits generated by the physical layer include the lowest four bits of the frame number; or,

the lowest five digits; or,

the lowest eight digits; or,

All ten.

It should also be noted that, in addition to the above frame number information, the information generated by the physical layer may further include other information, such as HFI.

It is assumed that at least two broadcast channels located in different aforementioned frames are QCL, repetitive or at least partially identical in specific content. Then Y=log ₂ (K)=1, N=log ₂ (P/10)=3, N+Y=4; at this time, the broadcast channel content generation scheme includes:

B41. The third target information in the first information is generated by the physical layer, and bits of the third target information do not include bits corresponding to frame numbers;

Specifically, the third target information includes at least part of the bits in the first information.

It should be noted that this situation refers to that when the first information includes information generated by the physical layer, there is no bit corresponding to the frame number in the information generated by the physical layer.

B42. The first information is generated by a higher layer;

It should be noted that this situation means that when any two broadcast channels in the same frame are QCL, repeated or at least partially the same, all the content in the broadcast channel is generated by the upper layer; for example, the indexes are all generated by The DMRS or synchronization sequence is carried. When any two broadcast channels in the same frame are QCL, repeated or at least partially the same specific content, all the content in the broadcast channel is generated by the higher layer.

It is assumed that the two broadcast channels at arbitrary indices of different above-mentioned frames are QCL, duplicate or at least partially identical in specific content. Then there are Y=log ₂ (K)=1, N=log ₂ (P/10)=3, N+Y=4, and the values that are not less than N and are multiples of 8 are 8, 16, etc. At this time, the broadcast channel The content generation scheme includes:

That is to say, when the terminal scrambles the bits generated by the physical layer, it does not scramble the bits related to the index among these bits, or uses the scrambling sequence used when scrambling the bits related to the index among these bits. or the scrambling bit is 0; specifically, when the receiving end receives the broadcast channel, it must first perform channel decoding on the fifth target information, and then descramble the fifth target information. The bits related to the index in the fifth target information are not descrambled, or the descrambling sequence or the descrambling bit used when descrambling the bits related to the index is 0.

It should also be noted that the sending end scrambles the fifth target information before channel coding the fifth target information, and optionally, when the sending end scrambles the fifth target information , you can use the following methods:

The bit related to the index in the fifth target information is not scrambled, or the scrambling sequence or scrambling bit used when scrambling the bit related to the index in the fifth target information is 0.

An example of the above situation is as follows:

Assuming that broadcast channels with the same index in different periods or different frames are QCL, repeated or at least partially the same in specific content, the physical layer generates some bits of the broadcast channel and the physical layer generates at least bits related to the index:

For example, the physical layer generation part includes at least the upper 3 bits of the index, or the lower 3 bits of the index, or all the bits of the index.

Example 1. Suppose that broadcast channels with the same value of index mod M1 in different periods or different frames or the same frame are QCL, repeating or at least some of the specific contents are the same, indicating that the index requires a total of Z bits. At this time, the physical layer generates the broadcast channel. Part of the bits, and the physical layer generation part includes at least index-related bits, and this part of the bits is related to M1:

bit bit, and DMRS carries the low of the index

bit bit.

Alternatively, the physical layer generation part contains all the bits of the index;

More specifically, it is assumed that the broadcast channels with odd indices are QCL, repeating or at least partially identical in specific content, and the broadcasting channels with even indices are QCL, repeating or at least partially identical in specific content, that is, M1=2, if Z=6, this Sometimes the generation part of the physical layer includes the high 6-1=5 bits of the index, and the DMRS carries the lowest 1 bit; or the generation part of the physical layer includes all 6 bits of the index.

More specifically, assuming M=4, if Z=6, then there is a physical layer generation part containing the high 6-2=4 bits of the index, and the DMRS carries the low 2 bits; or the physical layer generation part contains all 6 of the index. bits.

Example 2. Assuming that the broadcast channel with the same index/M2 value in different periods, different frames or the same frame is QCL, repeated or at least part of the specific content is the same, the indication index requires a total of Z bits, and the physical layer generates the broadcast channel. and the physical layer generation part contains at least index-related bits, and this part of bits is related to M2:

bit bit, and DMRS carries the high of the index

bit bit.

The physical layer generates part or all of the bits containing the index.

More specifically, assuming M=4, if Z=6, then there is a physical layer generation part that contains at least the lower 2 bits of the index, and the DMRS carries the upper 6-2=4 bits of the index; or the physical layer generation part contains the index of all 6 bits.

At this time, optionally, during the first scrambling, the bit part related to the index generated by the physical layer is not scrambled.

It should also be noted that when the first information is generated in the following manner: when the physical layer generates partial information and the higher layer generates partial information, the bits occupied by the first information satisfy one of the following:

The number of bits occupied by the partial information generated by the high layer is 24, and the number of bits occupied by the partial information generated by the physical layer is 8;

It should be noted that, assuming that the number of time-related information bits in the information generated by the physical layer is 4, the number of physical layer bits needs to be supplemented to 8 to align the number of bits. At this time, since the physical layer carries time-related information, the receiving end The descrambling process can be simplified, which is beneficial to reduce the detection complexity and improve the detection accuracy.

The number of bits occupied by the partial information generated by the high layer and the partial information generated by the physical layer are 16 respectively;

It should be noted that if the number of time-related information bits in the information generated by the physical layer is 9 (greater than 8), the number of physical layer bits needs to be supplemented to 16 to align the number of bits, which is beneficial to reduce the detection complexity and improve the detection accuracy. Spend.

The division of the upper layer and the physical layer is illustrated below with an example.

Example 1. If the broadcast channel TTI is 640ms and the broadcast channel period P=160ms, it is assumed that K=T/P=4. Assuming that the load of the broadcast channel (that is, the bits occupied by the content of the broadcast channel) is 32 bits, the content generation scheme of the broadcast channel includes:

The upper layer generates 24 bits, and the physical layer generates 8 bits;

Alternatively, the upper layer generates 16 bits and the physical layer generates 16 bits.

More specifically, for example, in combination with the above-mentioned situation that the broadcast channels with the same index are QCL, repeated, or at least partially the same specific content, the physical layer generation bit needs to contain at least 6-bit frame number and some index-related bits. At this time, a possible way It is the physical layer that generates 16 bits, and the 8 bits are respectively the 6-bit frame number LSB and the 2-bit index MSB, and may also contain other bits, such as at least one of HFI, other timing-related information, and reserved bits. Another possible way is that the physical layer generates 16 bits, including the 6-bit frame number LSB and part index, and may also include other bits, such as at least one of HFI, other timing-related information, and reserved bits. Another possible way is that the physical layer generates 16 bits, including an 8-bit frame number LSB and a partial index, and may also include other bits, such as at least one of HFI, other timing-related information, and reserved bits. Another possible way is that the physical layer generates 16 bits, including a 10-bit frame number LSB and a partial index, and may also include other bits, such as at least one of HFI, other timing-related information, and reserved bits.

More specifically, for example, in combination with the above-mentioned broadcast channel with the same value of index mod M1 as QCL, repeated or at least part of the same specific content, if M1=2, the physical layer generation bit needs to contain at least 6 bits of frame number LSB and 5. Bit index MSB, a possible way is that the physical layer generates 16 bits, including 6-bit frame number LSB and 5-bit index MSB, and may also include other bits, such as HFI, other timing-related information, reserved bits. at least one. Similarly, the physical layer generation bits may also include 8-bit or 10-bit frame number and index-related bits.

More specifically, for example, in combination with the above-mentioned broadcast channel with the same index/M2 value being QCL, repeated or at least partially the same specific content, if M2=2, the physical layer generation bit needs to contain at least 6 bits of frame number LSB and 2. Bit index LSB, at this time, a possible way is that the physical layer generates 8 bits, and the 8 bits are the 6-bit frame number LSB and the 2-bit index LSB; another possible way is that the physical layer generates 16 bits, including 6-bit frames The number LSB and the 2-bit index LSB may also contain other bits, such as at least one of HFI, other timing-related information, and reserved bits. Similarly, the physical layer generation bits may also include 8-bit or 10-bit frame number and index-related bits.

Example 2. If the broadcast channel TTI is 160ms or the broadcast channel period T=160ms, and it is assumed that a TTI with a length of 160ms or two broadcast channels located at any index in different frames in the period are QCL, repeating or at least partially identical in specific content , and the time interval between the frames where these broadcast channels are located is P. Suppose P=40ms. Assuming that the broadcast channel payload is 32 bits, the broadcast channel content generation scheme can be:

The upper layer generates 24 bits, and the physical layer generates 8 bits;

Alternatively, the upper layer generates 16 bits and the physical layer generates 16 bits.

More specifically, for example, in combination with the above-mentioned situation that the broadcast channels with the same index are QCL, repeated, or at least some of the specific content are the same, the physical layer generation bit needs to contain at least 4 bits of frame number and some index-related bits. At this time, a possible way It is the physical layer that generates 8 bits, which are respectively the 4-bit frame number LSB and the 3-bit index MSB, and may also contain other bits, such as at least one of HFI, other timing-related information, and reserved bits. Another possible way is that the physical layer generates 16 bits, including 4 bits of frame number LSB and 3 bits of index MSB, and may also include other bits, such as at least one of HFI, other timing-related information, and reserved bits. Similarly, the physical layer generation bits may also include 8-bit or 10-bit frame number and index-related bits.

More specifically, for example, in combination with the above-mentioned broadcast channel with the same index mod M1 value is QCL, repeated or at least partially the same specific content, if M1=2, the physical layer generation bit needs to contain at least 4 bits of frame number and 5 bits of frame number. Index MSB, at this time a possible way is that the physical layer generates 16 bits, including 4-bit frame number LSB and 5-bit index MSB, and may also include other bits, such as HFI, other timing-related information, at least one of the reserved bits one. Similarly, the physical layer generation bits may also include 8-bit or 10-bit frame number and index-related bits.

More specifically, for example, in combination with the above-mentioned broadcast channel with the same index/M2 value being QCL, repeated or at least partially the same specific content, if M2=2, the physical layer generation bit needs to contain at least a 4-bit frame number and a 2-bit index. LSB, at this time, a possible way is that the physical layer generates 8 bits, and the 8 bits are the 4-bit frame number LSB and the 2-bit index LSB; another possible way is that the physical layer generates 16 bits, including the 4-bit frame number LSB. and 2-bit index LSB, and may also contain other bits, such as at least one of HFI, other timing-related information, and reserved bits. Similarly, the physical layer generation bits may also include 8-bit or 10-bit frame number and index-related bits.

Example 3. If the broadcast channel TTI is 160ms or the broadcast channel period T=160ms, suppose a TTI with a length of 160ms or any broadcast channel located in the same frame in the period is QCL, repeating or at least some of the specific content is the same, assuming the broadcast channel payload For 32 bits, the broadcast channel content generation scheme may be: all 32 bits of the broadcast channel content are generated by a high layer.

If the broadcast channel TTI is 160ms or the broadcast channel period T = 160ms, assume a TTI of 160ms length or any broadcast channel in different frames in the period is QCL, repeating or at least partially identical in specific content, and the time between these frames The interval is 40ms, assuming K=2, then:

The bits generated by the physical layer need to contain at least the lowest 3 bits of the frame number. Assuming that the size of the broadcast channel is 32 bits, the generation methods can be as follows:

The upper layer generates 24 bits, and the physical layer generates 8 bits;

Alternatively, the upper layer generates 16 bits and the physical layer generates 16 bits.

It should be noted that the number of bits generated by the high and low layers can be obtained by combining Example 1 and Example 3, where the number of bits generated by the physical layer should be greater than or equal to the number of bits of necessary information that it needs to carry, and is a multiple of 8. For example, assuming that the broadcast channel payload is 32 bits, if at least a 6-bit frame number is required to be carried, it means that the bits generated by the physical layer may be 8 bits, 16 bits, 24 bits, or 32 bits.

An example of the frequency of scrambling code generation:

Example 1. If TTI=640ms and period P=160ms, assume that broadcast channels in different 160ms periods are QCL, repeating or at least partially identical in specific content

Generate the first scrambling code every time P;

A second scrambling code is generated per broadcast channel or per M1 or M2 or a common multiple of M1 and M2.

Direction 2: The arbitrary broadcast channel index between the above different frames is QCL, repeated, or at least part of the specific content is the same, specifically:

Generate the first scrambling code every P;

A second scrambling code is generated per broadcast channel or every P.

Example 3. If TTI=160ms and period P=160ms, assume that broadcast channels are QCL, repeated or at least partially identical in specific content within a 160ms period, and these broadcast channels are located in the same frame.

The first scrambling code is generated every cycle or TTI;

A second scrambling code is generated per broadcast channel or per M1 or M2 or a common multiple of M1 and M2.

Direction 2: Any broadcast channel index in the frame is QCL, repeated, or at least partially identical in specific content, specifically:

There is no need to perform the first scrambling, and the second scrambling is directly performed;

The scrambling code is generated every cycle or TTI, and the scrambling sequence is the same for all broadcast channels.
