However, in practical engineering, considering factors such as the transmission capacity of the optical port and the complexity of data processing, the number of channels retained is usually limited.

[0064] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0065] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0066] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0067] This application provides a method, device, apparatus, and storage medium for determining shaping channels to reduce user performance loss.

[0068] The methods, equipment, and apparatus are based on the same concept of the application. Since the methods, equipment, and apparatus solve problems in similar ways, their implementations can be referred to one another, and repeated details will not be repeated.

[0069] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G system (5GS).

[0070] Figure 1 This is a schematic diagram of the PUCCH receiving and shaping process provided in the embodiments of this application, as shown below. Figure 1 As shown, the received signal can be transformed into the beam domain by receiving beamforming, which changes the energy distribution of the signal in the receiving channel. Then, a beamforming channel with a predetermined target dimension can be selected by measuring the index, i.e., beamforming channel dimensionality reduction, which is used for back-end demodulation. This effectively reduces the data transmission pressure and processing complexity while ensuring throughput.

[0071] Control channels such as PUCCH, which carry access and feedback information, are often involved in multiple user multiplexing scenarios, especially Format 1 multi-user multiplexing configurations. In contrast, the receive shaping of PUCCH channels usually needs to retain more shaping channel dimensions to ensure demodulation performance.

[0072] However, in practical engineering, considering issues such as the transmission capacity of optical ports and the complexity of data processing, the channel retention dimension is usually limited. Therefore, the reasonable selection of shaped beams is an optimization direction to improve the shaped reception performance of PUCCH channels.

[0073] When selecting a beamforming channel, the operating range of the PUCCH channel is much lower than the noise level, so noise can affect the accuracy of the channel selection after beamforming, thus affecting uplink reception performance. In addition, when there are many multiplexed users, coupled with the channel angle spread effect, the distribution of user energy in each beamforming channel after beamforming will be relatively dispersed and uniform, and there will be more high-energy channels, which increases the difficulty of beamforming channel selection.

[0074] Therefore, embodiments of this application provide a method, apparatus, device, and storage medium for determining a shaping channel.

[0075] Figure 2 This is a flowchart illustrating the method for determining the shaping channel provided in an embodiment of this application, as shown below. Figure 2 As shown in the figure, this application provides a method for determining a beamforming channel, the execution subject of which can be a network-side device, such as a base station. The method includes the following steps:

[0076] Step 200: Determine the reference signal reception quality index for multiple target users that are being reused;

[0077] Step 210: Based on the reference signal reception quality index and the hierarchy of the reference signal reception quality index, sort the reference signal reception quality index to determine the first sort of the reference signal reception quality index.

[0078] Step 220: Determine the target beam domain channel based on the first ranking of the reference signal reception quality indicators;

[0079] The reference signal reception quality index includes: the reference signal reception quality index corresponding to each beam domain channel of any target user among the multiple multiple target users, and the reference signal reception quality index corresponding to the beam domain channel of the target user includes the reference signal reception quality index of the SRS signal in the beam domain channel of the target user.

[0080] The hierarchy of the reference signal reception quality index is used to characterize the position of the reference signal reception quality index in the second ranking, which is the size ranking of the reference signal reception quality indices of the target users corresponding to the reference signal reception quality index.

[0081] Optionally, the method for determining the shaping channel provided in the embodiments of this application is applicable to the PUCCH channel.

[0082] Optionally, the reference signal reception quality index can be any one or any combination of the following:

[0083] Reference Signal Receiving Power (RSRP);

[0084] Signal-to-noise ratio (SNR);

[0085] Signal-to-interference radio (SIR);

[0086] Signal-to-interference-noise ratio (SINR);

[0087] Received Signal Strength Indicator (RSSI).

[0088] Specifically Figure 3 This is a schematic diagram of channel energy distribution provided in an embodiment of this application, such as... Figure 3 As shown, the power distribution characteristics of the user channel directly reflect the energy distribution of the receiver's shaping channels. When the angle dispersion effect of the user channel is not significant, the channel characteristics tend to be similar to a Loss channel, with user energy concentrated in the first few sorted channels. When the angle dispersion effect of the user channel is significant, the channel characteristics tend to be similar to an NLoS channel, with user energy more dispersed. Therefore, for Los channel users, their energy is concentrated in the first few sorted channels, and demodulation can be supported by including fewer channels. For NLoS users, their energy distribution is more dispersed, requiring more channels to maintain demodulation performance.

[0089] Therefore, if the selection of channels is determined simply by sorting the reference signal reception quality indicators of all users, it may result in the following: because the higher-level reference signal reception quality indicators of some users with poor channel quality are lower than the lower-level reference signal reception quality indicators of users with poor channel quality, most of the beamforming channels of users with good channel quality will participate in demodulation, while the beamforming channels corresponding to the higher-level reference signal reception quality indicators of some users with poor channel quality will not be selected to participate in demodulation, thus leading to a deterioration in the communication performance of that user.

[0090] Optionally, in order to ensure the performance of users with poor channel quality, after determining all reference signal reception quality indicators of multiple target users, the reference signal reception quality indicators of all target users can be sorted based on the beam domain channel power distribution characteristics of the target users to obtain a first sort of all reference signal reception quality indicators. Then, based on the first sort, the shaped channel corresponding to the reference signal reception quality indicator with the highest sort can be determined as the target beam domain channel to ensure that the higher-level channels of users with poor channel quality can also participate in demodulation.

[0091] Optionally, to ensure the performance of users with poor channel quality, after determining the reference signal reception quality indicators (RSQIs) of multiple target users, the RQIs of all target users can be sorted based on the beam domain channel power distribution characteristics of the target users to obtain a first sort of RQIs. Then, based on this first sort, the shaped channel corresponding to the top-ranked RQI can be determined as the target beam domain channel, ensuring that higher-level channels of users with poor channel quality can also participate in demodulation.

[0092] Optionally, to ensure the performance of users with poor channel quality, after determining the reference signal reception quality indicators of multiple target users, the reference signal reception quality indicators of P target users can be sorted based on the beam domain channel power distribution characteristics of the target users to obtain a first sort of the reference signal reception quality indicators. Subsequently, the shaped channel corresponding to the top-ranked reference signal reception quality indicator can be determined as the target beam domain channel based on the first sort, so as to ensure that the higher-level channels of users with poor channel quality can also participate in demodulation. The reference signal reception quality indicators include: Q reference signal reception quality indicators corresponding to each of the P target users. The Q reference signal reception quality indicators corresponding to any target user can be the first Q reference signal reception quality indicators after sorting all the reference signal reception quality indicators corresponding to that target user from largest to smallest.

[0093] Wherein, P can be equal to or less than the number of target users; if P is less than the number of target users, then the P users can be randomly determined from all target users, or determined based on signal strength, without any limitation here.

[0094] Specifically, the level of the reference signal reception quality index corresponds to the position of the reference signal reception quality index in the second ranking, which is the ranking result of the reference signal reception quality index of the target user corresponding to the reference signal reception quality index from largest to smallest.

[0095] For example, taking the reference signal reception quality index RSRP as an example, all or the first Q RSRPs of the target user include RSRP1, RSRP2, RSRP3 and RSRP4, where RSRP1 > RSRP2 > RSRP3 > RSRP4. Then RSRP1 is the highest level (can be called the first level), RSRP2 is the second highest level (can be called the second level), RSRP3 is the second lowest level (can be called the third level), and RSRP4 is the lowest level (can be called the fourth level).

[0096] Specifically, when ranking the reference signal reception quality indicators of a target user based on the beam domain channel power distribution characteristics, the values ​​and levels of the reference signal reception quality indicators can be comprehensively considered to rank the indicators and determine the first ranking. This ensures that the highest-level reference signal reception quality indicator of some users with poor channel quality will always be ranked before the lower-level reference signal reception quality indicators of other users in the first ranking. It also ensures that the probability of the shaped channel corresponding to the highest-level reference signal reception quality indicator of some users with poor channel quality being selected for channel demodulation is higher than the probability of the shaped channel corresponding to the lower-level reference signal reception quality indicator of other users being selected for channel demodulation. In other words, it can bring the power levels of users with uneven channel quality to a horizontal level for comparison, thus reducing the difference in the probability of the shaped channel corresponding to users with different channel quality being selected for demodulation.

[0097] Optionally, for channel selection methods based on SRS (RSSI), RSSP, or SNR), the relevant technologies require that the power control relationship between the SRS channel and the PUCCH channel be known before the target beam domain channel can be determined. This places high demands on uplink receiver design. However, in most cases, uplink receivers use an independent power control mode where the power control relationship between the SRS channel and the PUCCH channel is unknown, making beamforming channel selection even more difficult. The embodiments of this application can bring the power levels of different users to a similar level for comparison even when the power control relationship between the SRS channel and the PUCCH channel is unknown. This is not limited by the power control relationship between the SRS and PUCCH channels and can significantly improve multiplexing performance based on the same channel selection dimension.

[0098] The method for determining the beamforming channel provided in this application sorts the reference signal reception quality index based on the reference signal reception quality index and its hierarchy, ensuring that the reference signal reception quality indexes of different users are compared at the same level. This reduces the probability difference between users with different channel qualities having their beamforming channels selected for demodulation, and avoids the inability of some low-quality channel users' higher-level reference signal reception quality indexes to participate in demodulation, thus preventing user performance degradation and effectively reducing user performance loss.

[0099] Optionally, the step of sorting the reference signal reception quality indicators based on the reference signal reception quality indicators and the hierarchy of the reference signal reception quality indicators to determine the first ranking of the reference signal reception quality indicators includes:

[0100] The reference signal reception quality index of each target user among the multiple target users is subjected to data standardization processing to determine the standard value reference signal reception quality index of each target user.

[0101] The standard reference signal reception quality indicators of the multiple target users are sorted from largest to smallest to determine the first ranking of the reference signal reception quality indicators.

[0102] Specifically, in order to more conveniently sort the reference signal reception quality index based on the reference signal reception quality index and the hierarchy of the reference signal reception quality index, the absolute channel signal quality index of each user can be generalized into a standard value that can be compared between users. Channel sorting and selection can balance the performance of high-power users and low-power users.

[0103] Specifically, the reference signal reception quality index of each target user can be standardized by taking the target user as the unit, and the standard value reference signal reception quality index of each target user can be determined. Then, the standard value reference signal reception quality indexes of all or part (P) target users can be sorted from largest to smallest to determine the first ranking of the reference signal reception quality indexes.

[0104] Specifically, the reference signal reception quality index for each target user at the first level can be uniformly set to the same first standard value;

[0105] Specifically, for any target user's reference signal reception quality index at the second level, the second standard value corresponding to the reference signal reception quality index at the second level can be determined based on the relationship between the target user's reference signal reception quality index at the first level and the first standard value, and the relationship between the target user's reference signal reception quality index at the first level and the reference signal reception quality index at the second level; and so on, all standard value reference signal reception quality indices for the target user can be determined; the standard value reference signal reception quality indices corresponding to all target users can be obtained in the same way.

[0106] For example, taking the reference signal reception quality index (RSRP) as an example, the RSRP of user C at the first level... c1 The RSRP of user C at level 20 is 20. c2 The RSRP of user C at level 3 is 15. c3 The RSRP of user D at the first level is 10. d1 The RSRP of user D at level 2 is 10. d2 The RSRP of user D at level 3 is 8. d3 The value is 5; the first standard value for the RSRP of each target user at the first level can be set to 1, then the RSRP of user C at the second level is 5. c2 The corresponding second standard value is 0.75, and the RSRP of user C at the third level is... c3 The corresponding third standard value is 0.5, which is the RSRP of user D at the second level. d2 The corresponding second standard value is 0.8, and the RSRP of user D at the third level. d3 The corresponding third standard value is 0.5.

[0107] For example, taking the reference signal reception quality index (RSRP) as an example, the RSRP of user E at the first level... e1 The RSRP of user E at level 20 is 20. e2 The RSRP of user E at level 3 is 10. e3 The RSRP of user F at level 2 is 2. f1 The RSRP of user F at level 20 is 20. f2 The RSRP of user F at level 3 is 19. f3 The value is 18; the first standard value for the RSRP of each target user at the first level can be set to 1, then the RSRP of user C at the second level will be... e2 The corresponding second standard value is 0.5, and the third-level RSRP for user C is... e3 The corresponding third standard value is 0.1, which is the RSRP of user D at the second level. f2The corresponding second standard value is 0.95, and the RSRP of user D at the third level. f3 The corresponding third standard value is 0.9.

[0108] Optionally, after obtaining the standard value reference signal reception quality index corresponding to each target user, the standard value reference signal reception quality index of all or some (P) target users can be sorted from largest to smallest to determine the first sort of the reference signal reception quality index.

[0109] For example, taking the Reference Signal Received Quality (RSRP) as the reference signal reception quality index, the RSRPs of users C and D, ranked from largest to smallest, are: 1, 1, 0.8, 0.75, 0.5, 0.5; therefore, the first ranking of the RSRPs of users C and D is: RSRP c1 RSRP d1 RSRP d2 RSRP c2 RSRP c3 RSRP d3 .

[0110] For example, taking the reference signal reception quality index (RSRP) as an example, the standard RSRP values ​​for users E and F, sorted from largest to smallest, are: 1, 1, 0.95, 0.9, 0.5, 0.1; therefore, the first ranking of the RSRP values ​​for users E and F is: RSRP e1 RSRP f1 RSRP f2 RSRP f3 RSRP e2 RSRP e3 .

[0111] Optionally, the step of performing data standardization processing on the reference signal reception quality index of each of the multiplexed target users to determine the standard value reference signal reception quality index for each target user includes:

[0112] For each of the multiple target users, the reference signal reception quality index corresponding to each beam domain channel of the target user is normalized to determine the standard value reference signal reception quality index corresponding to each beam domain channel of the target user.

[0113] Specifically, for any target user, the reference signal reception quality index of the target user can be normalized to obtain the standard value reference signal reception quality index corresponding to each beam domain channel of the target user.

[0114] For example, taking the Reference Signal Received Quality (RSRP) as an example, for any user UE1, the RSRP of all beam domain channels of UE1 can be calculated. idxUe After normalization, we obtain SN_RSRP. idxUe ;

[0115]

[0116] For example, RSRP of channel 1 of user G G1 For 20, the RSRP of channel 2 of user G is 20. G2 The RSRP of channel 3 for user G is 15. G3 If the value is 10, then after normalizing all or the first Q RSRP values ​​of user G, the standard value RSRP of channel 1 of user G is 1, the standard value RSRP of channel 2 of user G is 0.75, and the standard value RSRP of channel 3 of user G is 0.5.

[0117] For example, taking the reference signal reception quality index (RSRP) as an example, the RSRP of channel 1 of user H is... H1 The RSRP of channel 2 for user H is 10. H2 The RSRP of channel 3 for user H is 8. H3 If the value is 5, then after normalizing all or the first Q RSRP values ​​of user H, the standard value RSRP of channel 1 of user H is 1, the standard value RSRP of channel 2 of user H is 0.8, and the standard value RSRP of channel 3 of user H is 0.5.

[0118] After obtaining the standard value reference signal reception quality index for each user, the standard values ​​of all or some (P) users can be sorted from largest to smallest to obtain the first sort of the reference signal reception quality index.

[0119] Optionally, the step of performing data standardization processing on the reference signal reception quality index of each of the multiplexed target users to determine the standard value reference signal reception quality index for each target user includes:

[0120] For each of the multiple target users in the multiplexing, based on the weights corresponding to each beam domain channel of the target user, the reference signal reception quality index corresponding to each beam domain channel of the target user is normalized to determine the standard value reference signal reception quality index corresponding to each beam domain channel of the target user.

[0121] Specifically, when different beam domains correspond to different weights, for any target user, the reference signal reception quality index corresponding to each beam domain channel of the target user can be normalized based on the weights corresponding to each beam domain channel of the target user to obtain the standard value reference signal reception quality index corresponding to each beam domain channel of the target user.

[0122] For example, taking the Reference Signal Received Quality (RSRP) as an example, for a specific user UE, the RSRP of all beam domain channels of that UE can be calculated. idxUe After normalization, we get N_RSRP idxUe ;

[0123]

[0124] Subsequently, based on the weights corresponding to each beam domain channel of the target user, the N_RSRP corresponding to each beam domain channel of the target user is calculated. idxUe Weighting is performed to obtain the standard value SN_RSRP for each beam domain channel of the target user. idxUe ;

[0125] For example, taking the reference signal reception quality index (RSRP) as an example, the RSRP of channel 1 of user I is... I1 The RSRP of channel 2 for user I is 10. I2 For 8, the RSRP of channel 3 of user I is 8. I3 The weight is 5; channel 1 corresponds to a weight of 0.5, channel 2 corresponds to a weight of 0.3, and channel 3 corresponds to a weight of 0.2. After normalizing all or the first Q RSRPs of user H, the standard value RSRP of channel 1 for user H is 0.5 = 1 × 0.5, the standard value RSRP of channel 2 for user H is 0.24 = 0.8 × 0.3, and the standard value RSRP of channel 3 for user H is 0.1 = 0.5 × 0.2.

[0126] After obtaining the standard value reference signal reception quality index for each user, the standard values ​​of all or some (P) users can be sorted from largest to smallest to obtain the first sort of the reference signal reception quality index.

[0127] Optionally, the step of performing data standardization processing on the reference signal reception quality index of each of the multiplexed target users to determine the standard value reference signal reception quality index for each target user includes:

[0128] For each of the multiple target users in the multiplexing, the reference signal reception quality index corresponding to each beam domain channel of the target user is subjected to data normalization processing to obtain the initial standard value reference signal reception quality index corresponding to each beam domain channel of the target user.

[0129] Based on the weights of the target user and the initial standard reference signal reception quality index corresponding to each beam domain channel of the target user, the standard reference signal reception quality index corresponding to each beam domain channel of the target user is determined.

[0130] Specifically, with different weights for different users, for any target user, the reference signal reception quality index corresponding to each beam domain channel of the target user can be normalized to obtain the initial standard value reference signal reception quality index corresponding to each beam domain channel of the target user; then, based on the weights corresponding to each target user, the initial standard value reference signal reception quality index corresponding to each target user is weighted to determine the standard value reference signal reception quality index corresponding to each beam domain channel of the target user.

[0131] For example, taking the Reference Signal Received Quality (RSRP) as an example, for any user UE, the RSRP of all beam domain channels of that UE can be calculated. idxUe After normalization, we get N_RSRP idxUe ;

[0132]

[0133] Subsequently, based on the weights corresponding to the UE, the N_RSRP of all beam domain channels for that UE can be calculated. idxUe All values ​​are weighted to obtain the SN_RSRP of all beam domain channels for the UE. idxUe ;

[0134] For example, taking the reference signal reception quality index (RSRP) as an example, the RSRP of channel 1 of user J is... J1 The RSRP of channel 2 for user J is 20. J2 The RSRP of channel 3 for user J is 15. J3 If the value is 10, then after normalizing all or the first Q RSRP values ​​of user J, the initial standard value RSRP of channel 1 of user J is 1, the initial standard value RSRP of channel 2 of user J is 0.75, and the initial standard value RSRP of channel 3 of user J is 0.5.

[0135] RSRP of channel 1 for user K K1The RSRP of channel 2 for user K is 10. K2 For user K, the RSRP of channel 3 is 8. K3 If the value is 5, then after normalizing all or the first Q RSRP values ​​of user K, the initial standard value RSRP of channel 1 of user K is 1, the initial standard value RSRP of channel 2 of user K is 0.8, and the initial standard value RSRP of channel 3 of user K is 0.5.

[0136] Wherein, if the weight corresponding to user J is 0.6 and the weight corresponding to user K is 0.4, then the initial standard value RSRP of channel 1 for user J is 0.6 = 1 × 0.6, the initial standard value RSRP of channel 2 for user J is 0.45 = 0.75 × 0.6, and the initial standard value RSRP of channel 3 for user J is 0.3 = 0.5 × 0.6; the initial standard value RSRP of channel 1 for user K is 0.4 = 1 × 0.4, the initial standard value RSRP of channel 2 for user K is 0.32 = 0.8 × 0.4, and the initial standard value RSRP of channel 3 for user K is 0.2 = 0.5 × 0.4;

[0137] After obtaining the standard value reference signal reception quality index for each user, the standard values ​​of all or some (P) users can be sorted from largest to smallest to obtain the first sort of the reference signal reception quality index.

[0138] Optionally, determining the target beam domain channel based on the first ranking of the reference signal reception quality indicators includes:

[0139] The duplicate standard value reference signal reception quality indicators in the first sort are deduplicated to obtain the third sort, wherein the duplicate standard value reference signal reception quality indicators include standard value reference signal reception quality indicators that correspond to the same beam domain channel but belong to different target users.

[0140] Based on the third sorting, the beam domain channels corresponding to the top n reference signal reception quality indicators are determined as the target beam domain channels; where n is the number of target beam domain channels and n is a positive integer greater than 1.

[0141] Optionally, when determining the target beam domain channel based on the first ranking of the reference signal reception quality indicators, since different target users are multiplexed, different target users correspond to the same beamforming channel. Therefore, in the first ranking, each channel corresponds to multiple reference signal reception quality indicators. Thus, the duplicate reference signal reception quality indicators in the first ranking can be deduplicated to obtain a third ranking. In the third ranking, the beam domain channel corresponding to the first n reference signal reception quality indicators is determined as the target beam domain channel.

[0142] Optionally, the deduplication process for the duplicate reference signal reception quality index in the first sorting includes:

[0143] Only the largest of the repetitive standard reference signal reception quality indicators for each beam domain channel is retained.

[0144] Optionally, in order to demodulate each channel better, when performing deduplication processing on the repetitive standard reference signal reception quality index in the first sorting, the largest item in the repetitive standard reference signal reception quality index corresponding to each beam domain channel can be retained.

[0145] For example, taking the reference signal reception quality index (RSRP) as an example, the standard RSRP value for user L's channel 1 is 1, the standard RSRP value for user L's channel 2 is 0.75, and the standard RSRP value for user L's channel 3 is 0.5; the standard RSRP value for user M's channel 1 is 1, the standard RSRP value for user M's channel 2 is 0.8, and the initial standard RSRP value for user M's channel 3 is 0.5; the standard RSRP value for user N's ​​channel 3 is 1, the standard RSRP value for user N's ​​channel 1 is 0.4, and the initial standard RSRP value for user N's ​​channel 2 is... The initial standard value RSRP is 0.1; the first sort is obtained as: 1 (channel 1), 1 (channel 1), 1 (channel 3), 0.8 (channel 2), 0.75 (channel 2), 0.5 (channel 3), 0.5 (channel 3), 0.4 (channel 1), 0.1 (channel 2); after deduplication, the third sort is obtained as: 1 (channel 1), 1 (channel 3), 0.8 (channel 2); if n=2, that is, it is necessary to determine the beam domain channels corresponding to the first two RSRPs as the target beam domain channels, then the target beam domain channels can be determined as channel 1 and channel 3.

[0146] Figure 4 This is a schematic diagram of the PUCCH receiving and shaping process provided in the embodiments of this application, as shown below. Figure 4As shown, the received signal (i.e., the receiver's input signal) can first undergo time-frequency transformation and beamforming transformation to transform it into the beam domain. Then, the reference signal reception quality index (RSI) of the SRS signal for each user can be normalized to obtain user-level beam domain data (i.e., the standard reference RSI for each user). This user-level beam domain data can bring the data from different users to the same level for comparison and reflect the relative relationship of the reference RSI data within each user. Furthermore, channel weighting and / or user weighting can be added. For example, if different channels have different weights and / or different users have different weights, weighted user-level beam domain data needs to be obtained. Then, the (weighted) user-level beam domain data is sorted to obtain a first sort, and the target beam domain channel is determined based on the first sort, thus achieving PUCCH dimensionality reduction.

[0147] Figure 5 This is a schematic diagram of the shaping channel selection process provided in the embodiments of this application. Figure 5 As shown, the reference signal reception quality index of the SRS signal in the beam domain channel for each user can be obtained first based on the beam domain SRS information. idxUe Beam domain channel reference signal reception quality indicators for each user idxUe After normalization, the N-reference signal reception quality index is obtained. idxUe ;

[0148]

[0149] The design of channel weights or user weights can be tailored to different scenarios or purposes. This is achieved through the analysis of the standard value n_reference signal reception quality index. idxUe By applying weighted values, the standard value of the target user or beam can be changed, increasing the probability of being selected during sorting and indexing, thereby improving the reuse performance of the corresponding user.

[0150] Specifically, this can further improve the reception quality index of the N-reference signal. idxUe After sorting, the normalized and sorted pseudo-reference signal reception quality index for each user is obtained, denoted as the standard SN_reference signal reception quality index. idxUe value;

[0151] Specifically, this can then be applied to the standard value SN_reference signal reception quality index for all or some (P) users. idxUe The system performs sorting to obtain the first sort, and then performs deduplication to obtain the second sort, thereby obtaining the channel indices corresponding to the first n channels.

[0152] Specifically, based on the standard value SN_reference signal reception quality index of all or part (P) users after sorting. idxUe Prioritize selecting the index corresponding to the user channel with the larger standard value under the same level, and cumulatively select n-dimensional non-repeating channel indexes and send them to the PUCCH channel selection module.

[0153] The method for determining the beamforming channel provided in this application sorts the reference signal reception quality index based on the reference signal reception quality index and its hierarchy, ensuring that the reference signal reception quality indexes of different users are compared at the same level. This reduces the probability difference between users with different channel qualities having their beamforming channels selected for demodulation, and avoids the inability of some low-quality channel users' higher-level reference signal reception quality indexes to participate in demodulation, thus preventing user performance degradation and effectively reducing user performance loss.
