Description

An uplink control signal transmission method, network side device and terminal device

technical field

The present invention relates to the field of communication technologies, and in particular, to a method for transmitting an uplink control signal, a network side device and a terminal device.

Background technique

In the Long Term Evolution (English: Long Term Evolution, referred to as: LTE) system, the uplink physical channel includes: Physical Uplink Shared Channel (English: Physical Uplink Shared Channel, referred to as: PUSCH) and Physical Uplink Control Channel (English: Physical Uplink Control Channel) , referred to as: PUCCH).

PUCCH is used to carry control signaling, and different control signaling can be transmitted using different PUCCH transmission formats. For example, the user equipment may feed back a channel quality indicator (English: Channel Quality Indicator, CQI for short) through PUCCH format (Format) 2. If the base station requires the user equipment to simultaneously feed back CQI and positive acknowledgement information (English: Acknowledgement, abbreviated: ACK)/negative acknowledgement information (English: Negative Acknowledgement, abbreviated: NACK), the user equipment can pass PUCCH Format 2a (applicable to 1bit ACK/ NACK) or PUCCH Format2b (for ACK/NACK of 2 bits) feedback CQI and ACK/NACK.

In the LTE system, the resource allocation of the PUCCH channel is based on two physical resource blocks (English: Physical Resource Block, PRB for short) as the granularity. Each PRB occupies consecutive 12 subcarriers in the frequency domain and occupies one time slot in time. The 12 subcarriers of the two PRBs are completely different. For example, the 12 sub-carriers of the first PRB are sub-carriers in the low frequency band, and the 12 sub-carriers of the second PRB are sub-carriers in the high frequency band. This situation is called frequency hopping. The two PRBs are also referred to as one PUCCH domain. Each time slot includes 7 Single Carrier-Frequency Division Multiple Access (English: Single Carrier-Frequency Division Multiple Access, SC-FDMA) symbols in the time domain, wherein 2 SC-FDMA symbols are used for pilot transmission, The remaining 5 SC-FDMA symbols are used for data transmission (data in this text includes control data and traffic data), such as transmitting CQI.

In the existing LTE system, PUCCH signals from different users may be scheduled into the same PUCCH domain. In the same PUCCH domain, different users are distinguished by orthogonal code division multiplexing sequences. In one PUCCH domain, code division multiplexing of up to 12 users is allowed. Therefore, resource utilization is low.

Detailed ways

Embodiments of the present invention provide a method for transmitting an uplink control signal, a network side device, and a terminal device, so as to solve the technical problem of low resource utilization in the prior art.

In order to understand the technical solutions of the embodiments of the present invention more clearly, the embodiments of the present invention take the transmission mode of transmission control signaling of PUCCH Format 2/2a/2b in the LTE system as an example for description.

每个PRB包含连续的12个子载波，表示为

每个子载波之间的频率间隔为15KHz，时间上每1ms分为2个时隙(slot，表示为T_slot＝0.5ms)。每个时隙包含7个SC-FDMA符号，表示为

即为一个PRB。如图1所示，为一个上行时隙T_slot的资源的示意图，其中，一个子载波k和一个符号t对应一个资源元素(英文：Resource Element，简称：RE)。The LTE system uses Orthogonal Frequency Division Multiplexing (English: Orthogonal Frequency Division Multiplexing, OFDM for short) technology to subdivide "frequency" and "time" resources into: "subcarriers" and "SC-FDMA symbols". Taking 20MHz of LTE as an example, the available bandwidth of 18MHz on the frequency is divided into 100 PRBs, which are expressed as

Each PRB contains 12 consecutive subcarriers, denoted as

The frequency interval between each subcarrier is 15KHz, and every 1ms in time is divided into 2 time slots (slot, expressed as T _slot =0.5ms). Each slot contains 7 SC-FDMA symbols, denoted as

That is, a PRB. As shown in FIG. 1 , it is a schematic diagram of resources of one uplink time slot T _slot , wherein one subcarrier k and one symbol t correspond to one resource element (English: Resource Element, RE for short).

In the LTE system, the specific resource allocation of PUCCH is based on two PRBs. In the frequency domain, the frequency resources of the two PRBs are located on the two sides of the useful bandwidth, and the entire spectrum resource in the middle is used to transmit uplink data. It can effectively utilize spectrum resources and maintain the single-carrier characteristics of uplink transmission. In a subframe (1ms), in time slot 0, the uplink control signal is mapped to a PRB at the edge of the system frequency band, and in time slot 1, the uplink control signal is mapped to the corresponding PRB at the other edge of the system frequency band. . As shown in FIG. 2 , two PRBs with p=0 form one PUCCH region (also referred to as PUCCH resource). Similarly, two PRBs with p=1 form one PUCCH domain; two PRBs with p=2 form one PUCCH domain; and two PRBs with p=3 form one PUCCH domain. Wherein, p may be referred to as the resource number of the PUCCH.

用户在发送上行控制信号的时机到来时，会通过公式(1)和公式(2)来计算自己所使用的PRB。Usually, a network-side device, such as a base station (eg, eNB or eNodeB), will instruct the user in which subframes and which PRBs in the subframes to transmit uplink control signals, such as CQI, ACK/NACK. In the LTE system, the base station will send the PUCCH resource index of Format2/2a/2b

When the time to send the uplink control signal arrives, the user will calculate the PRB used by the user through formula (1) and formula (2).

表示向下取整。Among them, n _s is the time slot sequence number,

Indicates rounded down.

For example, it is calculated by formula (1) and formula (2) that in time slot 0, the PRB used by the user is PRB0, and in time slot 1, the PRB used by the user is PRB99. Therefore, the two PRBs are frequency hopping designs.

In a time slot, 7 symbols contain 2 pilot symbols and 5 data symbols, and two time slots contain a total of 14 symbols, 4 pilot symbols, and 10 data symbols. As mentioned above, each symbol Contains 12 sub-carriers.

After determining the PUCCH resource for sending the uplink control signal, the user needs to map the uplink control signal to the determined PRB next. Specifically, according to the coding design of the CQI in the LTE system, the uplink control signal of each user, such as the CQI between 4 and 11 bits, is channel-coded to obtain coded data of 20 bits, and then undergoes quadrature phase shift keying (English: Quadrature Phase Shift Keying, QPSK for short) is modulated into 10 modulated data, and the function of PUCCH Format2 is to send the 10 modulated data d(0),...,d(9) on 10 data symbols. The pilot symbol is usually used to transmit a pilot signal, and the pilot signal is, for example, a demodulation reference signal (English: Demodulation Reference Signal, DMRS for short).

In the LTE system, orthogonal code division multiplexing sequences are used on PUCCH Format2 to distinguish different users. Specifically, first select a base sequence with a length of 12, such as a Zadoff-Chu sequence. Then the base sequence is cyclically shifted to obtain 12 orthogonal cyclic shift sequences, also called code channels, each user uses 1 code channel. Then, 10 modulated data d(0),...,d(9) are modulated into 120 spread spectrum data, that is, each modulated data is spread spectrum through a sequence with a length of 12. Please refer to formula (3) for the spread spectrum modulation formula.

Indicates the number of PRBs fed back by Format2/2a/2b.

相关。本部分内容为本领域技术人员所熟知的内容(可以参考3GPP协议TS36.211中第5章)，所以在此不再详述。It can be seen from the above formula (4) that the generation of orthogonal sequences and the resource index

related. The content of this part is well known to those skilled in the art (refer to Chapter 5 in TS36.211 of the 3GPP protocol), so it will not be described in detail here.

Next, the UE maps its own 10 spread spectrum data obtained by formula (3) to the REs of PRB0 and PRB99. If there are 12 users multiplexing the same PUCCH resource at the same time, the two PRBs will carry 120 pieces of spread spectrum data.

If the CQI and ACK/NACK need to be fed back at the same time, the second pilot symbol in each time slot of the PUCCH resource is used to carry the data of the ACK/NACK, and the data of the ACK/NACK may be referred to as data d(10). However, in this way, in a PUCCH resource, only one pilot symbol can be used to carry the pilot signal in each time slot, and because the frequency hopping design is used between the two time slots, the channel characteristics are quite different. The 12 orthogonal pilots in the time slot are used for channel estimation, so the maximum number of orthogonal pilots on one PUCCH resource is 12.

Since code division multiplexing of up to 12 users can be allowed on one PUCCH resource, in the existing LTE system, one PUCCH resource supports up to 12 users to transmit uplink control signals. Therefore, resource utilization is low.

The implementation process and purpose of the solutions in the embodiments of the present invention will be described in detail below.

The uplink control signal to be sent is, for example, CQI and 1-bit ACK/NACK, and the CQI and ACK/NACK are transmitted through PUCCH format2a. The uplink control signal to be sent may also be CQI and ACK/NACK of 2 bits, and the CQI and ACK/NACK are transmitted through PUCCH format 2b.

Optionally, the encoding of the uplink control signal may be channel encoding. Generally speaking, the CQI is between 4 and 11 bits, and the encoded data of 20 bits is obtained through channel encoding.

Optionally, the modulation in step 101 may be QPSK modulation, so after the coded data of 20 bits is modulated by QPSK, 10 modulated data d(n), n=0,1,...,9 are obtained. Of course, this part of the content is illustrated by taking the existing LTE system as an example. In practical applications, the uplink control signal may be an uplink control signal that appears with the evolution of the system, and the coding method and modulation method may also be the same as the system evolution. A new coding method or modulation method appears, so the quantity of modulated data obtained can also be other values, that is, n can also be an integer greater than or equal to 10.

Next, the terminal device performs step 102, that is, using two orthogonal sequences to perform spread spectrum processing on the uplink modulated data to obtain spread spectrum data; wherein, the two orthogonal sequences are cyclically shifted based on the same base sequence. The resulting orthogonal sequence of bits. Optionally, the two orthogonal sequences are orthogonal sequences obtained by performing cyclic shift based on the same base sequence and according to the same cyclic shift rule.

It should be noted that, the terminal device may perform step 102 according to a protocol, or may perform step 102 according to an instruction. In the latter case, the terminal device further receives first indication information, where the first indication information is used to indicate that the terminal device needs to use two orthogonal sequences to perform spectrum spread processing on the uplink modulated data. Step 102 is performed only when the first indication information is received. If the terminal device does not receive the first indication information, or receives an instruction to instruct the terminal device to use only one orthogonal sequence to perform spread spectrum processing on the modulated data, the terminal device may use only one orthogonal sequence according to the prior art described above. The sequence method is used to spread spectrum, for example, the spread spectrum processing is performed by the aforementioned formula (3).

In addition, for the case of the aforementioned protocol agreement, it is applicable to the case that all terminal devices in the communication system support the use of two orthogonal sequences for spreading. In the case where an indication is required, it is compatible with the existing terminal equipment that cannot support the use of two orthogonal sequences for spreading.

Optionally, the terminal device receives the first indication information sent by the network side device, for example, the serving base station.

Wherein, the two orthogonal sequences may be preset orthogonal sequences, or may be calculated by the terminal device according to a predetermined rule. No matter which method is used, the two orthogonal sequences are obtained by performing cyclic shift based on the same base sequence. Orthogonal sequence of . The following will describe in detail how the terminal device calculates and obtains two orthogonal sequences according to a predetermined rule.

Both are any two different values within 0-11. For another example, the resource index

and resource index

Both are any two different values within 12-23. Of course, each PRB contains 12 subcarriers as an example for description. If the number of subcarriers contained in each PRB changes in the future with the development of communication technology, the resource index

and resource index

The numerical relationship between them also changes. For example, if the number of subcarriers is 24, the resource index

The difference is no more than 24. Therefore, the resource index

and resource index

The difference between them is not more than 12. For example, for each user, use any two resource index values from 0 to 11, that is, each user uses two code channels, which can theoretically be distinguished

Therefore, in theory, the spread spectrum method in this embodiment supports the multiplexing of 66 users. Compared with the prior art, which can only support the multiplexing of 12 users, the number of multiplexing users is greatly increased.

为长度为12的基序列，α通过以下公式(5)确定。optional,

Wherein, when j=0, it corresponds to the determination of the first orthogonal sequence, and when j=1, it corresponds to the determination of the second orthogonal sequence.

and if _ns mod 2=0, then

If _ns mod 2=1, then

It can be seen from the above description that the manner of determining the first orthogonal sequence is the same as the manner of determining the second orthogonal sequence, but the adopted resource index is different. Moreover, the above determination methods are well known to those skilled in the art. The difference is that in this embodiment, there are two different resource indexes, and two orthogonal sequences are obtained by calculation, while there is only one resource index in the prior art , so only an orthogonal sequence is obtained.

Of course, in practical application, the first orthogonal sequence and the second orthogonal sequence may be determined by different methods, which are not specifically limited in the present invention.

After the first orthogonal sequence and the second orthogonal sequence are determined, step 102 is executed next, that is, the terminal device uses the two orthogonal sequences to perform spectrum spread processing on the uplink modulated data.

Optionally, the terminal device performs spread spectrum processing on the uplink modulated data according to formula (6).

和第二正交序列

的和来进行扩频处理的。In formula (6), it is through the first orthogonal sequence

and the second orthogonal sequence

and for spread spectrum processing.

In practice, the terminal device can also receive another indication information, for example, the indication information that b is 0. In this case, the terminal device performs the spread spectrum processing in the same manner as in the prior art, please refer to formula (3). In other words, the spread spectrum processing method of formula (6) can be compatible with the spread spectrum processing method in the prior art and the spread spectrum processing method in the embodiment of the present invention. Of course, if there is no need to be compatible with the spread spectrum processing method in the prior art, that is, no indication information is required, and the agreement stipulates that the terminal device directly executes step 102, then the coefficient b can be directly removed from formula (6).

Next, the terminal device performs step 103, that is, the terminal device maps the spread spectrum data to the PRBs corresponding to the first time slot and the second time slot of the uplink transmission resource respectively. Wherein, the PRBs corresponding to the first time slot and the second time slot may be agreed in a protocol, or may be determined by a preset rule. Either way, the subcarriers contained in the PRB corresponding to the first time slot are exactly the same as the subcarriers contained in the PRB corresponding to the second time slot, that is, a non-frequency hopping structure. In other words, the PRB corresponding to the first time slot The included 12 subcarriers are exactly the same as the 12 subcarriers included in the PRB corresponding to the second time slot. This case applies to PUCCH format2/2a/2b. Please refer to FIG. 6 for the non-frequency hopping structure. For example, the PRBs with resource numbers p=1 corresponding to two time slots are the same PRBs.

Another situation is that the subcarriers included in the PRB corresponding to the first time slot are completely different from the subcarriers included in the PRB corresponding to the second time slot, that is, the frequency hopping structure, which is applicable to PUCCH format2. Because in PUCCH format2, both pilot symbols in each time slot can be used to transmit pilot sequences, so even if the frequency hopping structure is adopted, each time slot can transmit 24 pilot sequences, which can be used for 24 user use. In PUCCH format2a/2b, the second pilot symbol of each time slot is occupied and cannot be used to transmit the pilot sequence, so a non-frequency hopping structure needs to be adopted, so that the two pilot symbols of the two time slots are A total of 24 pilots are transmitted, which can be used by 24 users.

Because the spread spectrum method described above can support multiplexing of 66 users, and the number of pilot sequences can also be mentioned to 24, the maximum number of users supported by one uplink transmission resource can be increased to 24.

Optionally, the terminal device further receives second indication information, where the second indication information is used to indicate that the subcarriers included in the PRB corresponding to the first time slot are the same or different from the subcarriers included in the PRB corresponding to the second time slot. same.

Next, a method of determining PRBs corresponding to two time slots will be described.

该步骤和前述在确定两个正交序列时接收资源索引可以是同一个步骤。然后终端设备根据公式(7)确定两个时隙对应的PRB。Specifically, the terminal device receives the resource index

This step and the aforementioned step of receiving the resource index when determining two orthogonal sequences may be the same step. Then the terminal device determines the PRBs corresponding to the two time slots according to formula (7).

a为0即为前述第二指示信息，用于指示第一个时隙对应的PRB包含的子载波和所述第二个时隙对应的PRB包含的子载波相同。从公式(7)可以看出，当a为0时，PRB的位置和时隙无关，两个时隙下的PRB是一样的，所以两个时隙的PRB包含的子载波相同，例如均为子载波0至子载波11。而当a为1时，公式(7)和公式(2)相同，PRB的位置和时隙相关，不同时隙的PRB不相同，例如时隙0时，PRB为PRB0，而时隙1时，PRB为PRB99。in,

When a is 0, it is the aforementioned second indication information, which is used to indicate that the subcarriers included in the PRB corresponding to the first time slot are the same as the subcarriers included in the PRB corresponding to the second time slot. It can be seen from formula (7) that when a is 0, the position of the PRB has nothing to do with the time slot, and the PRBs in the two time slots are the same, so the PRBs in the two time slots contain the same subcarriers, for example, both Subcarrier 0 to Subcarrier 11. When a is 1, formula (7) is the same as formula (2), the position of PRB is related to the time slot, and the PRB of different time slots is not the same. For example, when time slot 0, the PRB is PRB0, and when time slot 1, PRB is PRB99.

In practical application, if it is not necessary to be compatible with the frequency hopping structure in the prior art, it can be directly agreed that a is 0 through the protocol, or the formula after a is 0 can be directly agreed to be used.

Next, the terminal device maps the spread spectrum data to the subcarriers on the PRB corresponding to the first time slot and the second time slot of the uplink transmission resource respectively and the SC-FDMA symbols used for data transmission. This part of the content is well known to those skilled in the art, so it will not be repeated here.

Next, in step 104, the terminal device places a pilot sequence on the SC-FDMA symbols used for pilot transmission on the PRBs corresponding to the first time slot and the second time slot respectively. It should be noted that the execution order of step 104 and step 103 does not limit the sequence. The content of placing the pilot sequence is well known to those skilled in the art, so it will not be described in detail here, and a method for determining the pilot sequence will be introduced below.

确定第一正交序列

终端设备根据公式(10)确定导频序列。Specifically, the terminal device according to the resource index

determine the first orthogonal sequence

The terminal equipment determines the pilot sequence according to formula (10).

等于

为[1,1]或者[1,-1]，在所述用于导频传输的SC-FDMA符号上携带的ACK或NACK信息时，z(e)为所述ACK或NACK信息，若未携带所述ACK或NACK信息，则z(e)为1。in,

is the pilot sequence,

is the number of SC-FDMA symbols used for pilot transmission in a time slot,

m' is the time slot number, m'=0,1,

equal

is [1,1] or [1,-1], when the ACK or NACK information carried on the SC-FDMA symbol used for pilot transmission, z(e) is the ACK or NACK information, if not Carrying the ACK or NACK information, z(e) is 1.

In detail, there are 4 pilot symbols in one uplink transmission resource, and there are 4*12=48 subcarriers in total, and formula (10) represents the pilot sequence corresponding to the 48 subcarriers. Among them, i is 0-11, which is used to traverse 12 subcarriers on one symbol. m' is 0 and 1 for traversing two slots. e is 0 and 1 for traversing 2 pilot symbols in each slot.

只有12个，可以记为P1,P2,P3,….,P12，其中，每个序列Pi的长度为12。In detail, the length of the pilot sequence on each pilot symbol is 12, and the first orthogonal sequence

There are only 12, which can be recorded as P1, P2, P3, ...., P12, where the length of each sequence Pi is 12.

From a single pilot symbol, the length of the pilot sequence is limited to 12, so there can only be 12 orthogonal pilot sequences. In the embodiment of the present application, a non-frequency hopping manner is adopted, and the first pilot symbol in the two time slots is regarded as a whole to form a sequence with a length of 24, so that there can be 24 orthogonal pilot sequences.

In the specific implementation process, there are many methods for how to create 24 orthogonal pilot sequences. Using [1,1]/[1,-1] is a simple method with little standard modification.

Specifically, the sequence P1 and the sequence P2 are orthogonal, and can be expressed as: P1*P2'=0.

For the first 12 users, the sequence on the first pilot symbol of the first slot and the sequence on the second pilot symbol of the second slot are sequentially used: [P1P1],[P2P2],[P3P3 ],...,[P12P12].

For the following users, the sequence on the first pilot symbol of the first slot and the sequence on the second pilot symbol of the second slot are in sequence: [P1-P1],[P2-P2], [P3-P3],...[P12–P12].

Then the pilot sequences of user 1 and user 2 are orthogonal: that is, [P1P1]*[P2P2]'=P1*P2'+P1*P2'=0.

The pilot sequences of user 1 and user 13 are orthogonal: that is, [P1P1]*[P1-P1]'=P1*P1'-P1*P1'=0. By analogy, the pilot sequences of every two users are orthogonal.

为[1,1]表示某个用户的导频序列在两个时隙的第一个导频符号上的导频序列是相同的。

为[1,-1]表示某个用户的导频序列在两个时隙的第一个导频符号上的序列是相反的。therefore,

For [1, 1], it means that the pilot sequence of a certain user's pilot sequence on the first pilot symbol of the two time slots is the same.

For [1,-1], it means that the sequence of a certain user's pilot sequence on the first pilot symbol of the two time slots is opposite.

为[1,1]或者[1,-1]可以是协议约定的，也可以是通过指示信息来指示，例如终端设备接收第三指示信息，第三指示信息用于指示：用户的导频序列在第一个时隙上的第一个导频符号上的序列和在第二个时隙上的第一个导频符号上的序列相反。optional,

is [1,1] or [1,-1], which may be agreed in the protocol or indicated by indication information. For example, the terminal device receives the third indication information, and the third indication information is used to indicate: the pilot sequence of the user The sequence on the first pilot symbol on the first slot is the opposite of the sequence on the first pilot symbol on the second slot.

In Table 1, the sequence index Noc is the aforementioned third indication information.

After steps 103 and 104 are completed, step 105 is executed next, that is, the terminal device sends uplink data, the uplink data includes the SC-FDMA symbols used for data transmission and the SC-FDMA symbols used for pilot transmission symbols, such as sending uplink data through physical antennas. This part of the content is well known to those skilled in the art, so it will not be repeated here.

确定。若K＝3，则表示a＝0,b＝1,Noc＝1，同时表示使用两个正交序列进行扩频处理，两个正交序列分别由资源索引

确定。In addition, optionally, the aforementioned first indication information, second indication information, and third indication information may be indicated by the same indication field, for example, indicated by the scheme parameter K, if K=0, it means a=1, b= 0, Noc=0. Orthogonal sequences are indexed by resource

Sure. At this time, it means that the terminal device is working in the existing mode. If K=1, it means a=0, b=0, Noc=0, and at the same time, it means that an orthogonal sequence is used for spreading processing, and the orthogonal sequence is indexed by the resource

Sure. If K=2, it means a=0, b=1, Noc=0, and at the same time, it means that two orthogonal sequences are used for spreading processing, and the two orthogonal sequences are respectively indexed by the resource

and resource index

Sure. If K=3, it means a=0, b=1, Noc=1, and at the same time, it means that two orthogonal sequences are used for spreading processing, and the two orthogonal sequences are respectively indexed by the resource

and resource index

Sure.

On the network side equipment side, the network side equipment determines two physical resource blocks PRBs of uplink transmission resources for the terminal equipment to send uplink data; wherein, the time slots where the two PRBs are located are different; the network side equipment is on the two PRBs Receive the uplink data and the pilot sequence; wherein, the uplink data is spread spectrum data spread by two orthogonal sequences; the pilot sequences of different terminal equipment are orthogonal to each other; the network side equipment according to the terminal equipment The sent pilot sequence demodulates the uplink data sent by the terminal device.

The method for determining the two PRBs of the uplink data sent by the terminal device by the network side device is the same as that determined by the aforementioned terminal device side, for example, it is also determined by formula (7).

It is well known to those skilled in the art that the network side equipment receives uplink data and pilot sequences on the two PRBs, and demodulates the uplink data according to the pilot sequences. For example, channel estimation based on the pilot sequences can be used. The maximum likelihood (ML) algorithm is used to demodulate the uplink data, so it is not repeated here.

Optionally, the network side device further sends any one or any combination of the foregoing first indication information to third indication information to the terminal device.

和资源索引

Optionally, the network side device also sends the resource index to the terminal device

and resource index

The following examples will be used to illustrate, please refer to Table 2.

分别为0、2、4、6、8、10。用户7-18分别使用2个码道，每个用户使用1、3、5、7、9、11中的任意两个码道，分别通过资源索引

和资源索引

指示。在理论上，每个用户使用1、3、5、7、9、11中的任意两个码道，那么就可以支持

个用户复用，但是因为导频序列只有6个码道的2倍，即12，因为每个用户需要使用一个正交导频序列来区分，所以这里只支持12个用户复用，所以加上使用1个码道的6个用户，达到上行传输资源支持18个用户的复用的技术效果。In Table 2, users 1-6 use one code channel respectively, and the corresponding resource index

0, 2, 4, 6, 8, 10, respectively. Users 7-18 use 2 code channels respectively, and each user uses any two code channels among 1, 3, 5, 7, 9, and 11, respectively through the resource index

and resource index

instruct. In theory, each user uses any two code channels in 1, 3, 5, 7, 9, and 11, then it can support

Multiple users are multiplexed, but because the pilot sequence is only twice as long as 6 code channels, that is, 12, and because each user needs to use an orthogonal pilot sequence to distinguish, only 12 users are supported here for multiplexing, so add Using 6 users of 1 code channel achieves the technical effect that uplink transmission resources support the multiplexing of 18 users.
