Background

In the field of communication, multiple access technology enables multiple terminal devices to access a base station simultaneously for communication, and ensures that signals between the terminal devices do not interfere with each other, and successfully detects signals sent by the terminal devices. In the non-orthogonal code division multiple access technology, a characteristic sequence is allocated to terminal equipment based on the difference of received power, so that the method is an effective means for reducing mutual interference among the terminal equipment and improving the capacity of the whole system.

At present, the traditional allocation method explicitly measures the received power of the signal of each sending end reaching the receiving end, so as to allocate a characteristic sequence for the terminal equipment according to the received power, thereby achieving the purposes of avoiding mutual interference and ensuring measurement accuracy. However, such measurement needs to be performed one by one in a time division manner, that is, the base station needs to measure the received power of the signal transmitted by each terminal device one by one in a time division manner, so that the overhead in the process of allocating the feature sequence by the conventional allocation method is large.

Some concepts and/or terms related to a codebook allocation method, apparatus, device, system and storage medium provided in the embodiments of the present application are explained below.

1. Multiple access and orthogonal multiple access

Multiple access is also called multiuser access, and aims to enable multiple terminal devices to access a base station (or an access point) simultaneously for communication, ensure that signals between the terminal devices do not interfere with each other, and successfully detect signals sent by the terminal devices. Multiple access includes frequency division multiple access (Frequency Division Multiple Access, FDMA), time division multiple access (Time Division Multiple Access, TDMA), code division multiple access (Code Division Multiple Access, CDMA).

FDMA: frequency division multiple access uses different frequency bands to distinguish the terminal devices, i.e. the data of the terminal devices are transmitted on different frequency bands, thereby avoiding mutual interference of signals between the terminal devices. The principle of FDMA is: user1, user2, user3, user4, user5, and User6 transmit data at frequency points f1, f2, f3, f4, f5, and f6, respectively. Corresponding guard bands are arranged among the frequency points, so that the signal of each user is not interfered by other users.

Based on FDMA, the orthogonal frequency division multiple access (Orthogonal Frequency-Division Multiple Access, OFDMA) further compresses the frequency band, and improves the frequency spectrum utilization rate. The bands overlap between users, but the other signal energy is 0 at the point where the power of each user band is greatest, so at the point of maximum power of each user band, the individual user signals remain orthogonal.

TDMA: different time slots are used for distinguishing users, namely, data of the users are transmitted on the different time slots, so that mutual interference of signals among the users is avoided. The principle of TDMA is: user1, user2, user3, user4, user5, and User6 transmit data over time slots t1, t2, t3, t4, t5, and t6, respectively. The time of each time slot can not overlap each other, so that the signal of each user is not interfered by other users.

CDMA: code division multiple access uses different orthogonal codewords to distinguish users, i.e., the data of the users is spread and/or scrambled with unused codewords, thereby avoiding mutual interference of signals between the users. The principle of CDMA is: userA, userB, userC respectively adopts three groups of orthogonal code words CA, CB and CC, when information is transmitted, if the information bit is 0, the inverted code word (namely-CA, -CB, -CC) is transmitted, and if the information bit is 1, the code word is directly transmitted. The three users send information using the same physical resources (frequency, time), so the receiving end obtains the codeword superposition vector d of the three users. Since the codewords are orthogonal, the result of the correlation (conjugate multiplication or transpose multiplication) of the different codewords is 0. Therefore, the receiving end can separate out the information transmitted by each user by only carrying out correlation operation on the received vector and the code word of each user.

In the above multiple access methods, since the information of the user is orthogonal in the frequency domain, the time domain, or the code domain, there is no interference between the signals transmitted by the users. These access modes are collectively referred to as orthogonal multiple access (Orthogonal Multiple Access, OMA).

It should be noted that, both the 4G LTE and the 5G NR adopt OFDMA as a multiple access manner, so that transmission resources used by each user are orthogonal in a time-frequency domain, and a minimum unit of independent resources is defined as 1 Resource Element (RE) in a standard.

2. Non-orthogonal multiple access (NOMA)

The access technology corresponding to the orthogonal multiple access is a Non-orthogonal multiple access (NOMA) technology. "non-orthogonal" refers to Multiple users sharing the same physical resource for transmission, which will generate multi-user interference (Multiple User Interference, MUI), also known as Multiple ACCESS INTERFERENCE, MAI, at the receiving end. Although new interference is introduced, the receiving end can eliminate or minimize the negative effect of MAI through advanced detection algorithms, such as serial interference cancellation (Successive Interference Cancellation, SIC), so as to obtain higher spectral efficiency.

According to the difference of the uplink and downlink channel characteristics, the NOMA technology applicable to the uplink and downlink needs to be studied.

For cellular communication systems, the downlink communication is actually a point-to-multipoint channel, i.e. a broadcast channel. In the broadcast channel, each user is able to fully receive all the information sent by the base station, whether or not the information is data of interest to that user. In other words, multiple receivers will receive different copies of the same signal transmitted by the same transmitter, with the different copies differing in that they may experience different channels.

The upper bound of the channel capacity of the broadcast channel is the gaussian broadcast channel bound (Gaussian Broadcast Channel Bound, GBC bound)

Where R _i is the rate of the ith user, W is the bandwidth, α _i is the power ratio of the ith user, N _i is the noise power spectral density of the ith user, and P is the power spectral density of the transmitted signal.

Orthogonal multiple access is not able to reach the broadcast channel capacity limit. Researches show that the capacity boundary of a broadcast channel can be obtained through multi-user superposition coding and SIC, so that the downlink communication capacity and the frequency spectrum efficiency are improved. The so-called multi-user superposition coding is a key idea of the downstream NOMA technology.

On the other hand, the uplink communication of a cellular communication system is effectively a multipoint-to-single point channel, such a channel being referred to as a Multiple access channel (Multiple ACCESS CHANNEL, MAC). Unlike downstream communication, in upstream communication, multiple transmitting ends transmit different signals to the same receiving end, and different signals will likely experience different channels. The upper bound of the channel capacity of the MAC is Gaussian multiple Access channel bound (Gaussian MAC Bound, GMAC bound)

Where R _k is the rate of the kth user, S is the set of users, K is the total number of users, P _k is the transmit power of the kth user, and N ₀ is the noise power.

TDMA/FDMA is much smaller than the capacity bound, which can be achieved in certain situations by time or frequency division relaxing the power limitation. It is worth mentioning that OFDMA is a specific way of implementing a frequency division scheme called loose power limitation. In general, for uplink communications, the orthogonal multiple access approach fails to reach the capacity bound under prevailing conditions, but the capacity bound is available under certain special conditions. Therefore, compared with the downlink, the purpose of adopting the NOMA technology in the uplink is not to simply improve the spectrum efficiency, but to strongly call limited physical resources to provide overload capacity, thereby improving the concurrent connection number of the communication system and supporting massive connection scenes.

3. Uplink non-orthogonal multiple access technology

The research stage researches the downstream NOMA, and proposes various schemes, and the schemes can be divided into code division and interleaving in a large scale. Wherein the code division includes two operations of spreading and scrambling. Spread-based code division non-orthogonal multiple access techniques (hereinafter non-orthogonal code division multiple access) are mainly described herein without ambiguity.

Similar to the orthogonal code division multiple access described earlier, each user will be assigned 1 or more signature sequences (Signature Sequence), also known as spreading sequences. During transmission, the transmitting end multiplies each symbol to be transmitted by the characteristic sequence, and the actually transmitted symbols are also expanded from 1 to K, wherein K is the length of the characteristic sequence and is also called as an expansion factor (SPREADING FACTOR). The difference is that in OMA, the codes allocated by different users are orthogonal to each other, so when signals sent by all users arrive synchronously at the receiving end, the receiving end can obtain the symbol before expansion sent by the sending end by using the feature sequence corresponding to each user, and at the same time, completely eliminate interference information from other users, i.e. no MAI exists.

However, for the orthogonal code division multiple access, the length of the signature sequence and the number of signature sequences are consistent, that is, the codebook with the spreading factor of 4 has only 4 signature sequences, and only 4 users can be supported for concurrent transmission. To increase the number of concurrent connections, non-orthogonal code division multiple access allows for incomplete orthogonality between different signature sequences.

In fact, in information theory, the achievable channel capacity for orthogonal code division multiple access and non-orthogonal code division multiple access is the same. For a general CDMA system, its capacity C _sum can be written as

Wherein I _K is a unit array with length/width of K; s= [ S ₁,...s_K]^T ] is a codebook matrix constructed from K feature sequences (S _i is the feature sequence of the i-th user); p=diag (P ₁,...p_K) is a diagonal matrix of K users 'powers (P _i is the i-th user's power). The maximum value of equation (1) can be obtained when p=pi _K,S^TS＝I_K, that is, the received powers of all users are equal and the characteristic sequences are orthogonal to each other. However, equation (1) is practically equivalent to

At this time, the maximum value of the capacity is obtained at p=pi _N,SS^T＝K/N I_N. It can be seen that at this point, although the maximum achievable capacity is equal, orthogonality between the signature sequences is no longer required, only the codebook is required to satisfy SS ^T＝K/N I_N, and the number of codes available is changed from K to N. Since the spreading factor K is equal to the number of REs required to transmit 1 symbol and is also equal to the codebook size, for example, a system with spreading factor of 4 can support 4 users to share 4 REs to transmit 1 symbol respectively, it can be found that when the number of codes changes from K to N, the codebook size is no longer limited by the spreading factor or the number of REs, or in average, 1 RE can carry more than 1 user symbol.

Obviously, when orthogonality between the signature sequences is not guaranteed, the obtained symbols are affected by MAI even if the received signal is despread at the receiving end with the signature sequence of each user, and the symbol detection Mean Square Error (MSE) of all users is given by

Wherein r is a received signal vector; b _i is the signal sent by the ith user; σ ² is the noise power.

The codebook that minimizes MSE is referred to as the Welch Bound Equality (WBE) codebook.

In addition to using WBE codebooks, non-orthogonal code division multiple access also relies on SIC to reduce MAI. Similar to downstream NOMA, here the SIC step is: the receiving end detects the symbols of the user in turn from high to low according to the received power, and reconstructs the symbols of the user into interference signals after each detection, and then removes the interference signals from the received signals. It has been found that when detecting user symbols with a large received power, it is necessary to consider symbols from other users as noise. Therefore, if the received power difference of the signals of different users at the receiving end is large, the performance of the SIC will be better.

4. Non-orthogonal code division multiple access technology based on power grouping

In the spread-based code division non-orthogonal multiple access technique described above, the WBE codebook is relied primarily on to boost the number of concurrent users, and the SIC receiver suppresses MAI.

On the one hand, as known from the working principle of SIC, the larger the difference in received power (at the receiving end) between users is, the better. On the other hand, as is clear from equation (2), the more equal the received power is, the larger the capacity is for the WBE codebook. In order to solve the contradiction between SIC and WBE codebooks, further improvements to WBE codebooks are needed.

It is easy to find that when SIC is used, only users with smaller received power will interfere with users with larger received power. Thus, an improved idea of the conventional WBE codebook is to allocate the signature sequence according to the magnitude of the received power. For example, for the user with the highest received power, a feature sequence with the lowest cross-correlation value with all other feature sequences can be found from the WBE codebook, and so on.

It is obvious that it is relatively complex to assign a specific feature sequence for each user. Therefore, users and codebooks can be grouped, wherein the grouping of users is based on the received power, the received power in the group is as close as possible, and the received power difference between groups is large. Accordingly, the better the cross-correlation (i.e., the lower the cross-correlation value) should be assigned to the group with the higher received power.

Specifically, it is assumed that G groups of users exist, and the average value of the received power of the signals at the receiving end isThen the optimal codebook s _g allocated to the G group user should satisfy the condition

Such a method may be referred to as a power-packet based code division non-orthogonal multiple access technique. Compared with the direct random allocation WBE codebook, the method based on the power grouping can effectively reduce MAI and improve the capacity and the spectrum efficiency of the whole system.

The codebook allocation method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

As described in the background, in the non-orthogonal code division multiple access technology, the allocation of the feature sequences based on the difference of the received power is an effective means for reducing the inter-user interference and improving the overall system capacity. However, the conventional allocation method needs to explicitly measure the received power at which the signal of each transmitting end arrives at the receiving end. Such measurements are usually carried out one by one in a time-division or the like manner, so that mutual interference is avoided and measurement accuracy is ensured. This introduces significant overhead, i.e., the overhead in the conventional allocation method of feature sequences.

To solve the above problem, in the embodiment of the present application, the first device sends the first signal on at least two physical channels, so that the second device can obtain the group codebook configuration from the first signal according to the first configuration, where the first configuration includes relevant parameters for demodulating the signal and receiving the group codebook configuration, the first signal on at least two physical channels carries at least two group codebook configurations, and symbols of the first signal on each physical channel are generated by data mapping of one group codebook configuration, and each group codebook configuration is carried by the first signal on one or more physical channels. In the scheme, the selectivity of the signal analysis difficulty of different orthogonal physical channels to the channel condition is utilized, the blind distribution of the codebook to the user groups with different receiving power can be realized, so that the network side equipment does not need to measure the receiving power of the signal sent by each terminal equipment one by one, then the terminal equipment is grouped, and finally the codebook or the characteristic sequence is distributed to the terminal equipment of different groups; and the codebook is directly distributed to all terminal equipment in a blind way, the codebook distribution cost based on the power grouping is reduced in a closed loop but explicit feedback-free control mode, and meanwhile, the effectiveness of the distributed codebook is ensured.

An embodiment of the present application provides a codebook allocation method, and fig. 2 shows a flowchart of the codebook allocation method provided by the embodiment of the present application. As shown in fig. 2, the codebook allocation method provided by the embodiment of the present application may include the following steps 201 to 203.

Step 201, a first device transmits a first signal on at least two physical channels.

In an embodiment of the present application, the first signal on the at least two physical channels carries at least two group codebook configurations, and symbols of the first signal on each physical channel are generated by data mapping of one group codebook configuration, and each group codebook configuration is carried by the first signal on one or more physical channels. The first signal is used by the second device to obtain a group codebook configuration according to a first configuration including relevant parameters for demodulating the signal and receiving the group codebook configuration.

Step 202, the second device obtains a first configuration.

In an embodiment of the present application, the first configuration includes relevant parameters for demodulating the signal and receiving the group codebook configuration.

It will be appreciated that the first configuration described above refers to parameters associated with transmitting and receiving a group codebook configuration for modulating and demodulating an nth (1N) signal.

Step 203, the second device receives the first signal on at least two physical channels and obtains a group codebook configuration from the first configuration and the first signal received on the at least two physical channels.

In an embodiment of the present application, the first signal on the at least two physical channels carries at least two group codebook configurations, and symbols of the first signal on each physical channel are generated by data mapping of one group codebook configuration, and each group codebook configuration is carried by the first signal on one or more physical channels.

In the embodiment of the application, it is proposed that the similar effects are realized by differentiated power, modulation order symbol rate and coding rate on a plurality of orthogonal physical channels. Based on the consistency of the uplink and downlink communication channels on a large scale, if the complexity of each terminal device is the same (for example, the algorithm is the same and the iteration times are the same), the demodulation capability of the terminal device on signals with different difficulties (determined by power, modulation order, symbol rate and coding rate) can also reflect the signal strength of the signal sent by the terminal device at the base station.

Specifically, the base station transmits different group codebook configurations with signals of different demodulation difficulties on different orthogonal physical channels, and agrees with the terminal equipment about the configurations of the receiving and demodulation sequence of the channels, the demodulation rule of each channel, the codebook use priority and the like. According to the channel conditions of users, the demodulation difficulty of signals carried by different physical channels is different, so that the probability of successfully resolving the codebooks of different groups by the terminal equipment is different, for example, the probability of successfully resolving the signals with higher demodulation difficulty by the terminal equipment with closer distance (or equivalently, the average signal intensity of the signals sent by the terminal equipment at the base station is higher) is higher. In other words, by utilizing the selectivity of the signal demodulation difficulty on different physical channels to the channel condition of the terminal equipment, the signal with higher demodulation difficulty can be used for transmitting the group codebook with higher receiving power to the terminal equipment with close distance and better channel condition, and at the moment, the terminal equipment with far distance and worse channel condition can not successfully analyze the codebook naturally or with smaller probability.

The base station does not need to measure the receiving power of the signals sent by each UE one by one (each terminal device is usually required to be polled in a TDMA mode), then groups the terminal devices, and finally distributes codebooks or feature sequences to the terminal devices in different groups; and the codebook is directly distributed to all terminal equipment in a blind way, the codebook distribution cost based on the power grouping is reduced in a closed loop but explicit feedback-free control mode, and meanwhile, the effectiveness of the distributed codebook is ensured.

It will be appreciated that the symbols of the nth signal are generated by a data map belonging to 1 group codebook configuration, but each group codebook configuration may be carried by more than 1 physical channel. In other words, data belonging to 1 group codebook configuration will be mapped to symbols of at least 1 physical channel for transmission.

It should be noted that, the signal transmitted on the nth physical channel may be referred to as an nth signal, where N belongs to 1, …, N is the total number of physical channels; the nth signal may contain more than 1 symbol.

Alternatively, in the embodiment of the present application, the "the second device obtains the group codebook configuration according to the first configuration and the first signal received on at least two physical channels" in the step 203 may be specifically implemented by the following step 203 a.

In step 203a, the second device demodulates the symbols of the first signal received on at least two physical channels according to the first configuration, to obtain a group codebook configuration of the first signal bearer on each physical channel.

Optionally, in the embodiment of the present application, before obtaining the configuration of the group codebook, the second device may perform data processing on the demodulated data in a second manner, where the second manner is a combining manner, a CRC check manner, a channel decoding manner, and a deinterleaving manner.

In the embodiment of the application, different physical channels carrying different groups of codebook configurations are mapped to physical resources in an orthogonal mode, wherein the physical resources can be time, frequency and orthogonal codes, respectively correspond to FDM, TDM and CDM, and can be any combination of the three. In particular, if CDM is involved, the symbols to be transmitted also need to undergo a spreading operation of orthogonal codes before being mapped to time and/or frequency resources. Accordingly, the despreading of the orthogonal code is required at the receiving end.

For simplicity, the FDM approach is illustrated herein. Consider that 1 independent physical channel is carried on 2 orthogonal frequencies (f ₁ and f ₂), respectively, and the base station transmits different group codebook configurations on these 2 physical channels at different powers, such as p ₁ and p ₂, respectively, where p ₁＞p₂. It is assumed that the data of each group codebook configuration is QPSK modulated, i.e. each symbol carries 2 data bits. If the final size of the data configured by each group codebook is 1000 bits after CRC operation, it can be understood that the first device can send 500 symbols at 2 frequencies respectively to complete the distribution of the group codebook once.

The process of the second device obtaining the group codebook configuration is as follows:

(1) Receiving a signal on a first physical channel (frequency p ₁＞p₂), judging the received signal to obtain a first symbol, and mapping to obtain a first group of data bits configured by a codebook;

(2) Receiving a signal on a second physical channel (frequency f ₂), judging the received signal to obtain a second symbol, and mapping to obtain a second group of data bits configured by a codebook;

(3) After 500 symbols are received on two physical channels respectively, splicing the data bits configured by the first group of codebook and the second group of codebook, and performing CRC;

(4) If the second set of codebook configurations passes the CRC, using the second set of codebook configurations; if the second set of codebook configurations fails to pass the CRC and the first set of codebook configurations fails to pass the CRC, then the first set of codebook configurations is used; otherwise, default group codebook configuration is used, or no access is subsequently made.

It should be noted that the above procedure is to receive and decode all the group codebook configurations, and then select 1 group codebook configuration; another method is as follows: and firstly obtaining a first group of codebook configuration, judging whether a first condition is met, if so, continuing to obtain a next group of codebook configuration, iterating until the next group of codebook configuration fails to meet the first condition, and using the current group of codebook configuration. The above procedure takes as an example that the power of the two physical channels is different but the modulation order, symbol rate, coding rate are the same, and in practice these parameters may also be different.

The embodiment of the application provides a codebook allocation method, a first device sends a first signal on at least two physical channels, so that a second device can obtain a group codebook configuration from the first signal according to a first configuration, wherein the first configuration comprises related parameters for demodulating the signal and receiving the group codebook configuration, the first signal on the at least two physical channels carries at least two group codebook configurations, symbols of the first signal on each physical channel are generated by data mapping of one group codebook configuration, and each group codebook configuration is carried by the first signal on one or more physical channels. In the scheme, the selectivity of the signal analysis difficulty of different orthogonal physical channels to the channel condition is utilized, the blind distribution of the codebook to the user groups with different receiving power can be realized, so that the network side equipment does not need to measure the receiving power of the signal sent by each terminal equipment one by one, then the terminal equipment is grouped, and finally the codebook or the characteristic sequence is distributed to the terminal equipment of different groups; and the codebook is directly distributed to all terminal equipment in a blind way, the codebook distribution cost based on the power grouping is reduced in a closed loop but explicit feedback-free control mode, and meanwhile, the effectiveness of the distributed codebook is ensured.

Optionally, the codebook allocation method provided by the embodiment of the present application further includes the following steps 301 to 303.

Step 301, the first device continues to allocate a group codebook to the second device in the first configuration.

In the embodiment of the application, the first device blindly distributes the codebook to the second device in the first configuration, and the second device obtains a group codebook configuration or a default group codebook configuration.

Step 302, the first device sends indication information to the second device.

In the embodiment of the present application, the indication information is used to indicate the second device to perform uplink transmission according to the obtained group codebook configuration.

Step 303, the first device determines the updated first configuration and/or the updated group codebook configuration according to the usage condition of each group codebook, and continues to allocate the group codebook to the second device until the allocation of the group codebook is completed.

Optionally, in an embodiment of the present application, the usage of the codebook includes at least one of: the number or probability of collision of the feature sequence, the number or probability of no collision of the feature sequence, the number or probability of transmission failure, and the number or probability of transmission success.

In the embodiment of the present application, in the blind distribution of the group codebook, because the first device lacks the prior information about the second device, the second device uses the same group codebook configuration too intensively, possibly due to reasons such as improper signal transmission parameters or codebook size, so that the possibility of collision of the feature sequences (generally, if the same feature sequence is used, the receiving end cannot distinguish different users) is increased. In order to solve the problem, the implementation mode is expanded to an iterative mode based on the implementation mode, and is used for further closed-loop adjustment of the group codebook, so that the distribution effectiveness of the group codebook is improved, and explicit measurement and feedback are not needed.

Optionally, the codebook allocation method provided by the embodiment of the present application further includes the following step 304.

The second device demodulates the first signals on each physical channel in turn, and when one group codebook configuration meeting the first condition is obtained, one group codebook configuration meeting the first condition is used for uplink access.

Optionally, in the embodiment of the present application, the second device may subsequently adopt a group codebook configuration (for example, a feature sequence) that satisfies the first condition:

demodulating signals of all physical channels to obtain all group codebook configurations, and selecting 1 group codebook configuration according to a first condition;

Or demodulating the signals of each physical channel in turn (from difficult to easy), and stopping processing the first signal after obtaining the configuration of the group codebook meeting the first condition;

or sequentially demodulating (from easy to difficult) the signals of the respective physical channels, and stopping processing the first signal when the group codebook configuration that does not satisfy the first condition is obtained.

The difficulty here refers to a degree of difficulty in demodulating a signal, and the degree of difficulty in demodulating a signal may be determined based on some parameter of the signal (for example, power (power ratio)). For example, a signal with higher power (power ratio) is easier to demodulate.

It should be noted that, for a plurality of group codebook configurations that satisfy the first condition, the second device may select the group codebook configuration according to the priority of the first configuration.

Optionally, in the embodiment of the present application, for the second device that cannot obtain the group codebook configuration from the first signal, a default group codebook configuration may be adopted, or may not be accessed later.
