In the 5G NR system, the base station generates a PSS sequence and an SSS sequence for synchronization, and generates a PBCH according to the main information block (MIB). The PBCH, PSS, and SSS form an SS block, and the base station can scan the beam through Send one or more SS blocks; when the terminal performs initial access, it first detects the PSS for synchronization, then detects the SSS to obtain the cell identity, and finally demodulates the PBCH resource block to obtain information related to initial access, including the system frame number used for synchronization ( At least one of system frame number, SFN), half-frame indication, time index of SS block, and the like. In NR, one PSS OFDM symbol, one SSS OFDM symbol and two or more PBCH OFDM symbols together form a resource block, which is called a synchronization block (SS block). In the SS block, PSS symbols and SSS symbols It has a fixed time-domain distribution relationship with the position of the PBCH symbol and is adjacent to each other.

The contents of the MIB transmitted in the PBCH include: at least part of the SFN, SS burst set period, SS block time index, SS block number, half-frame indication, etc. one or more.

Currently, in NR, there are 6 synchronous signal segment set (SS burst set) cycles, which are 5ms, 10ms, 20ms, 40ms, 80ms and 160ms. These 6 cycle forms require at least 3 bits for indication. For 5ms SSburst cycle , and 1 bit is required to indicate field information, therefore, a total of 4 bits of data are required.

In addition, the transmission of the SS block is beam scanning, so the number and/or time index of the synchronization block (SS block) need to be indicated in the PBCH. According to NR, the maximum number of beams is 64, so the number of SS blocks needs to be indicated by 6 bits , the time index of the SS block also needs 6 bits, and these two indications cause a relatively large overhead of the PBCH.

This application proposes a transmission method of indication information, which can reduce the overhead of PBCH. Referring to FIG. 5, the method includes:

501. The network device generates a synchronization signal block SS block, the SS block includes a synchronization signal SS resource block and a physical broadcast channel PBCH resource block, wherein the X bit in the PBCH resource block is used to indicate the first half frame of the 10ms frame and/or Or the second half frame, and at least one of the SS burst set periods of various synchronization signal segment sets;

SS resource blocks may include at least one of PSS and SSS resource blocks.

502. Send the SS block.

In an example, X=3bit, the first half frame and the second half frame of the 10ms frame are the first half frame and the second half frame of the 10ms frame with a 5ms SS burst set period, and the various SS burst set periods include: 5ms, 10ms, 20ms, 40ms, 80ms, 160ms at least one. The synchronization signal SS includes at least one of PSS and SSS, and the synchronization signal SS resource block includes at least one of PSS and SSS resource blocks.

The 3 bits can indicate the above-mentioned various contents, but the SS block sent by the network device may only indicate at least one of them in a certain period of time, for example, only indicate the 10ms SS burst set period, or only indicate the 10ms of the 5ms SS burst set period The first half of the frame.

Correspondingly, the terminal device receives the SS block, the SS block includes the SS resource block and the PBCH resource block, wherein the X bit in the PBCH resource block is used to indicate the first half frame and the second half frame of the 10ms frame, and various synchronization Signal segment set SS burst set period; demodulate the PBCH resource block to obtain the corresponding SS burst set period and/or half-frame information.

In the above embodiment, the half-frame information is indicated together with several SS burst set periods. The 3bits data has a total of 8 values: 000, 001, 010, 011, 100, 101, 110, 111, while the SS burst set period has only 6 cases, 5ms, 10ms, 20ms, 40ms , 80ms and 160ms; a frame is 10ms, only 5ms SS burst set needs to indicate the first half frame and the second half frame, plus the remaining 5 kinds of SS burst periods, a total of 7 situations; and 3bits data has a total of 8 values, so it is enough Indicates the above 7 situations.

For example: 000 indicates the first half of a 10ms frame of a 5ms SS burst set, 001 indicates the second half of a 10ms frame of a 5ms SS burst set, 010 indicates a 10ms SS burst set period, 011 indicates a 20ms SS burst set period, and 100 indicates a 40ms SS burst set period, 101 indicates the 80ms SS burst set period, and 110 indicates the 160ms SSburst set period. In this way, the information originally required to be indicated by 4 bits of data can be indicated by 3 bits. The above values are just an example, and different values may be adopted.

In addition, 000 can also indicate the 5ms SS burst set, 001 can indicate the first half frame, 010 can indicate the second half frame, and 011, 100, 101, 110, 111 can indicate the following 5 cycles. At this time, 8 cases of 3-bit values are used up.

Another embodiment of the present application proposes a method for transmitting indication information, which can reduce the overhead of the PBCH. The method includes: the process is similar to that in Figure 5, including:

The network device generates a synchronization signal block SS block, the SS block includes a synchronization signal SS resource block and a physical broadcast channel PBCH resource block, and sends the SS block; wherein,

The X bits in the PBCH resource block are used to indicate the number of SS blocks and/or the time index, and the N-X bits are used to indicate the system frame number; under different SS burst set periods, the value of X is different, and N is a fixed value. X, N are all integers.

Correspondingly, the terminal device receives the SS block, and demodulates the PBCH resource block to obtain the number and/or time index of the corresponding SS block.

In an example, when the SS burst set period is 5 ms or 10 ms, X=5; or when the SS burst set period is above 20 ms, X=6.

NR defines that the maximum number of SS blocks in the SS burst set is 64, so 6 bits are required to indicate the number of SS blocks or the time index. In another embodiment, it is proposed to further subdivide the number of SS blocks on different periods, and use part of the bits of the system frame number on different periods to indicate the number of SS blocks or the time index.

For example, the number of SS blocks in the 20ms SS burst set period, 40ms SS burst set period, 80ms SSburst set period and 160ms SS burst set period in NR is defined as a maximum of 64, and 6bits data is required to indicate the number of SS blocks or the time index; The maximum number of beams with a period of 10ms and a period of 5ms is 32, and 5bits data is required to indicate the number of SS blocks or the time index of the SS block.

Referring to Figure 6, for an SS burst set period of 20 ms and above, at least 1 bit of the SFN is residual information, and this 1 bit can be borrowed to indicate the number of SS blocks or the time index, which can be the last bit of the SFN, so that 6 bits , there is 1 bit at the last bit of the SFN, so only 5 bits are actually used, which saves the overhead of the PBCH.

For example, as shown in Figure 6, the last 1 bit of the SFN in the 20ms SS burst set period is 0, so this 1 bit is redundant and can be used to indicate the number of SS blocks or the time index, so that it can be used to indicate the number of SS blocks Or the 6 bits of the time index are 5 bits plus 1 bit SFN, and the 1 bit SFN can be the last bit of the SFN; the 6 bits indication information includes the 1 bit SFN, which saves overhead.

In yet another embodiment, the flow is similar to that in FIG. 5 , the network device generates a synchronization signal block SS block, and the SS block includes a synchronization signal SS resource block and a physical broadcast channel PBCH resource block, wherein at least one of the following conditions is satisfied: in the PBCH resource block The X bits of the 5ms SS burst set are used to indicate the number and/or time index of the SS block; the X+1 bit in the PBCH resource block is used to indicate the number and/or time index of the SS block of the 10ms SS burst set; the PBCH resource The X+2 bits in the block are used to indicate the number and/or time index of the SS block of the 20ms SS burst set; the X+3 bits in the PBCH resource block are used to indicate the number and/or the number of SS blocks of the SS burst set above 40ms time index;

Send the SS block.

1 bit in the X+1 bits is a borrowed field indication;

1 bit in the X+2 bits indicates the last bit of the system frame number bit, and 1 bit indicates the borrowed half frame;

Two of the X+3 bits are the last two bits indicating the system frame number, and one bit is an indication of a borrowed half-frame.

In one embodiment X=3.

The terminal device receives the SS block, demodulates the PBCH resource block to obtain the number and/or time index of the corresponding SS block.

NR defines that the maximum number of SS blocks in the SS burst set is 64, so 6 bits are required to indicate the number of SS blocks, or 6 bits are required to indicate the time index of the SS block. The present invention proposes to further subdivide the number of SS blocks in different periods, and use the SFN partial data and half-frame indication information in different periods to indicate the number of SS blocks or the time index of the SS block. For example, in the 5ms SS burst set period in NR, the maximum number of SS blocks is defined as 8, and 3 bits are required for indication; for the 10ms SS burst set period, the maximum number of SS blocks is defined as 16, and 4 bits are required for indication; The maximum number of SS blocks is defined as 32, and 5 bits are required for indication; for 40ms SS burst set period and above, the maximum number of SS blocks is defined as 64, and 6 bits are required for indication.

For the SS burst set period of 10ms and above, the half-frame indication is not used, so it can be used to indicate the number of SS blocks or the time index of the SS block, so that the number of SS blocks or the time of the SS block in the 10ms SS burst set period The 4-bit data indication method of the index is: 3-bit SS block number or SS block time index plus 1-bit half-frame indication.

For the SS burst set period of 20ms and above, the last bit of the SFN is not used. For example, as shown in Figure 6, the last bit of the SFN of the 20ms SS burst set period is 0, indicating that the position of the SS burst set has been indicated The 1-bit information of the SFN can be used to indicate the number of SS blocks or the time index of the SS block. In this way, the number of SS blocks in the 20ms SS burst set period or the 5-bit data indication method of the time index of the SS block is: 3-bits of the number of SS blocks Or the time index of the SS block plus the half-frame indication of 1 bits plus the last bit of the SFN of 1 bits.

For the SS burst set period of 40ms and above, the last two bits of SFN do not change. For example, as shown in Figure 6, the last 2 bits of SFN in the 40ms SS burst set period are all 0, indicating that the position of the SS burst set has been indicated The 2bits information of the SFN can be used to indicate the number of SS blocks or the time index of the SS block. In this way, the number of SS blocks in the SS burst set period of 40ms or the 6bits data indication method of the time index of the SS block is: the number of SS blocks of 3 bits Or the time index of the SS block plus the half-frame indication of 1 bits plus the last two bits of the SFN of 2 bits.

In another embodiment, since the SS burst set period itself carries part of the frame information, at least one of SFN, period and field information may be combined to implement a joint indication to save the number of bits.

The flow of the method is similar to that in FIG. 5 , the network device generates a synchronization signal block SS block, the SS block includes a synchronization signal SS resource block and a physical broadcast channel PBCH resource block, and sends the SS block.

Among them, at least one of the following conditions is met:

The X bit in the PBCH resource block is used to indicate the first half frame, the second half frame, and the 10ms SS burst set period of the 10ms frame under the 5ms SS burst set period;

The X+1 bit in the PBCH resource block is used to indicate the 20ms SS burst set;

The X+2 bits in the PBCH resource block are used to indicate the 40ms SS burst set period;

The X+3 bits in the PBCH resource block are used to indicate the 80ms SS burst set period; the X+4 bits in the PBCH resource block are used to indicate the 160ms SS burst set period;

One of the X+1 bits is the last one of the borrowed indication system frame number bits;

The 2 bits in the X+2 bits are the last 2 bits of the borrowed indication system frame number bits;

The 3 bits in the X+3 bits are the last 3 bits of the borrowed indication system frame number bits;

The 4 bits in the X+4 bits are the last 4 bits of the borrowed indication system frame number bits.

For example: X=2.

Correspondingly, the terminal device receives the SS block, and demodulates the PBCH resource block to obtain a corresponding SS burst set period.

For example, refer to Figure 7 and Table 1 below: the combined indication of period and half frame (abbreviated as A) has 2 bits, where: 00 respectively indicates the 5msSS burst set period and the first half frame under the 5msSS burst set period, and 01 indicates 5msSS burstset respectively Period and the second half frame under the 5ms SS burst set period, 10 means the 10ms SS burst set period. When the SSburst set period is greater than 10ms, that is, 20, 40, 80, 160ms, it is represented by 11. The frame indication under 5ms and 10ms is indicated by SFN, which is to indicate the frame number where the current SS block is located. The values 00, 01, and 11 are just examples, and different ways can be adopted for the values.

Referring to Figure 7, one frame is 10ms, when the SS burst set period is 20ms, since the SS burst set occurs every 2 frames, the last bit of the SFN is always 0. Therefore, the last bit of SFN can be used to distinguish whether the period is 20ms or greater when the period is greater than 10ms. If A=11, the last bit of SFN is 0, and the period is 20ms. When A=11 and the last bit of SFN is 1, it is a period greater than 20ms, such as 40, 80, 160ms.

Therefore, when the SS burst set period is 20ms, the period and field frame joint indication, and the last bit of the SFN are used to indicate the number of SS blocks or the time index.

Referring to Figure 7, one frame is 10ms. When the SS burst set period is 40ms, since the SS burst set only appears once every 4 frames, the second last bit of SFN is always 0. Therefore, the penultimate digit of SFN can be used to distinguish whether the cycle is 40 ms or a larger cycle when the cycle is greater than 20 ms. If A=11, the last bit of SFN is 1, and the penultimate bit of SFN is 0, then the period is 40ms. If A=11, the last bit of SFN is 1, and the penultimate bit of SFN is 1, then it is a period greater than 40ms, such as 80, 160ms.

Therefore, when the SS burst set period is 40 ms, the combined indication of the period and half frame, and the last 2 bits of the SFN are used to indicate the number of SS blocks or the time index.

Referring to Figure 7, one frame is 10ms. When the SS burst set period is 80ms, since the SS burst set only appears once every 8 frames, the third last bit of SFN is always 0. Therefore, the penultimate 3rd bit of SFN can be used to distinguish when the period is greater than 40ms, whether it is 80ms or a larger period. If A=11, the last bit of the SFN is 1, the second last bit of the SFN is 1, and the third last bit of the SFN is 0, then the period is 80ms. If A=11, the last bit of the SFN is 1, the second last bit of the SFN is 1, and the third last bit of the SFN is 1, then the period is greater than 80ms, such as a period of 160ms.

Therefore, when the SS burst set period is 80ms, the period and field frame joint indication, and the last 3 bits of the SFN are used to indicate the number of SS blocks or the time index.

Similarly, when the SS burst set period is 160ms, the combined indication of the period and half frame, and the last 4 bits of the SFN are used to indicate the number of SS blocks or the time index.

By analogy, the period greater than 80 ms can be indicated through the SFN. See Table 1 and Table 2 below for details.

Table 1. Note: X indicates that it is determined by the frame number where the current SS block is located.

Of course, it can also be indicated by the following table 2, that is, the specific period is indicated by the value of SFN equal to 1, instead of the specific period by the value equal to 0, that is to say, the value of SFN in the above table 1 is 0, 1 Can be swapped.
