[0049] Figure 1 This is a flowchart illustrating an antenna selection method provided in an embodiment of this disclosure. A wireless communication system may include a transmitter and a receiver. This method can be applied to the transmitter, whereby the transmitter selects an antenna and sends the selection result to the receiver. Alternatively, the method can be applied to the receiver, whereby the receiver selects an antenna and sends the selection result to the transmitter. The method can also be applied to a controller between the transmitter and receiver, whereby the controller selects an antenna and sends the selection result to both the transmitter and receiver. This disclosure does not impose any limitations. Figure 1 As shown, the antenna selection method includes steps S101-S103.

[0050] Step S101: Determine multiple combinations of first antennas from the first antenna set of the first communication terminal.

[0051] In embodiments of this disclosure, the first communication end can be a transmitter or a receiver; when the first communication end is a transmitter, the second communication end is a receiver; when the first communication end is a receiver, the second communication end is a transmitter. The first antenna assembly includes at least one antenna.

[0052] By identifying multiple combinations of first antennas in the first antenna set of the first communication terminal, a search guide is provided for subsequent antenna searches.

[0053] Step S102: Determine the first search order, which is the order in which antenna combination searches are performed among multiple first antenna combinations.

[0054] In embodiments of this disclosure, the first search order can be the order in which multiple first antenna combinations are searched for.

[0055] By determining the first search order for multiple first antenna combinations, the search process of the antenna combination can be standardized, the disorder and chaos of the search process can be reduced, and the search efficiency of the antenna combination can be improved.

[0056] Step S103: Determine the target antenna selection result that satisfies the preset antenna selection conditions, at least according to the first search order; the target antenna selection result includes the target first antenna combination and the target second antenna combination, and the target second antenna combination includes at least one antenna in the second antenna set of the second communication terminal.

[0057] In the embodiments of this disclosure, the first communication terminal may deploy multiple antennas, and the second communication terminal may deploy multiple antennas. This disclosure does not limit the number of antennas deployed on the first and second communication terminals. The preset antenna selection criteria can be a standard for determining whether an antenna combination scheme meets communication requirements. The antenna combination scheme can be a target first antenna group selected by the first communication terminal and a target second antenna combination selected by the second communication terminal. This disclosure does not limit the specific conditions of the preset antenna selection criteria. The target first antenna combination may include a number of first antenna selections, and the target second antenna combination may include a number of second antenna selections.

[0058] By searching according to the first search order and determining the target antenna selection results, which include the target first antenna combination and the target second antenna combination, based on the preset antenna selection conditions, the antenna configurations of the first communication end and the second communication end jointly meet the communication requirements, reducing the need to search for all antenna combinations, reducing the amount of computation during the search process, and improving the efficiency of antenna selection.

[0059] According to the antenna selection method proposed in this disclosure, the method includes: determining a plurality of first antenna combinations from a first antenna set at a first communication terminal; determining a first search order, which is the order in which antenna combinations are searched among the plurality of first antenna combinations; and determining a target antenna selection result that satisfies preset antenna selection conditions, at least according to the first search order. The target antenna selection result includes a target first antenna combination and a target second antenna combination, wherein the target second antenna combination includes at least one antenna from a second antenna set at a second communication terminal. The first search order limits the search order of the first antenna combinations, and antenna selection at least according to the first search order achieves directional search, reduces the complexity of antenna selection, and thus improves antenna selection efficiency.

[0060] For example, when performing the task of determining the target antenna selection result that satisfies the preset antenna selection conditions based at least according to the first search order, the task can be implemented in the following manner, but is not limited to: determining a second search order for each antenna in the second antenna set under each first antenna combination; the second search order being the order in which antennas are searched in the second antenna set; and determining the target antenna selection result that satisfies the preset antenna selection conditions based on the first search order and the second search order.

[0061] In embodiments of this disclosure, the second search order can be the retrieval order of each antenna at the second communication terminal under a single first antenna combination. The second search order of the antennas in the second antenna set may differ under each first antenna combination.

[0062] By determining the second search order of each antenna in the second antenna set under each first antenna combination, the antenna search order of the second communication end can be adaptively adjusted for different first antenna combinations of the first communication end, thereby improving the accuracy of antenna selection.

[0063] For example, when determining multiple first antenna combinations in the first antenna set of the first communication terminal, the following methods may be used, but are not limited to: exhaustively traversing the antennas in the first antenna set according to the number of first antenna selections to enumerate multiple first antenna combinations, each first antenna combination including the number of first antenna selections.

[0064] In the embodiments of this disclosure, the value of the number of first antennas selected is not limited. The number of first antennas selected can be flexibly adjusted according to actual needs and application scenarios, thereby improving the flexibility of first antenna combination selection.

[0065] For example, when determining the first search order, it can be implemented in the following ways, but is not limited to: determining a first channel quality metric between each first antenna combination and the second antenna set; sorting the first antenna combinations corresponding to the first channel quality metric in descending order of the first channel quality metric to obtain a first sorting result for each first antenna combination; and determining the first search order based on the first sorting result.

[0066] In the embodiments of this disclosure, the first channel quality metric can be the maximum singular value, and the specific calculation method of the maximum singular value is not limited in the embodiments of this disclosure. By determining the first search order according to the descending order of the first channel quality metric, antenna combinations with better channel quality are searched first. During the search process, antenna combinations that meet the preset antenna selection conditions can be found earlier, reducing the computational load of antenna selection and improving the efficiency of antenna selection.

[0067] For example, when performing the execution of determining the second search order of each antenna in the second antenna set under each first antenna combination, it can be implemented in the following manner, but is not limited to: determining the channel response strength between each first antenna combination and each antenna in the second antenna set; sorting each antenna in the second antenna set under each first antenna combination in descending order of channel response strength to obtain a second sorting result for each antenna in the second antenna set under each first antenna combination; and determining the second search order based on the second sorting result.

[0068] In embodiments of this disclosure, the channel response strength can be the norm of the column vector containing each antenna in the second antenna set of the channel matrix. The channel matrix can be constructed based on each first antenna combination and each antenna in the second antenna set. Embodiments of this disclosure do not limit the specific calculation method of the norm.

[0069] By determining the second search order based on the descending order of channel response strength under each first antenna combination, antennas with stronger signal response in the second antenna set under each first antenna combination can be searched first, thereby improving antenna selection efficiency.

[0070] For example, when determining the target antenna selection result that satisfies the preset antenna selection conditions according to the first search order and the second search order, it can be implemented in the following manner, but is not limited to: determining the current search first antenna combination among a plurality of first antenna combinations according to the first search order; determining the current search second antenna combination in the second antenna set according to the second search order of each antenna in the second antenna set under the current search first antenna combination and the second preset antenna selection number of the second antenna set; the second preset antenna selection number is less than the total number of antennas in the second antenna set; in response to the current search antenna selection result satisfying the preset antenna selection conditions, determining the current search antenna selection result as the target antenna selection result; the current search antenna selection result includes the current search first antenna combination and the current search second antenna combination.

[0071] In the embodiments of this disclosure, the specific value of the second preset antenna selection number is not limited. The second preset antenna selection number can be flexibly set according to actual needs and application scenarios, thereby improving the flexibility of antenna selection.

[0072] For example, when determining the current search second antenna combination in the second antenna set based on the second search order of each antenna in the second antenna set under the current search first antenna combination and the second preset number of antenna selections in the second antenna set, it can be implemented in the following manner, but is not limited to: determining an antenna subset in the second antenna set based on the second search order of each antenna in the second antenna set under the current search first antenna combination; the antenna subset includes the currently searched antenna and all antennas after the currently searched antenna; determining a second channel quality metric between the current search first antenna combination and the antenna subset; and determining the current search second antenna combination based on the second search order of each antenna in the second antenna set under the current search first antenna combination, the second preset number of antenna selections, and the second channel quality metric.

[0073] In the embodiments of this disclosure, the currently searched first antenna combination can be the first antenna combination currently being searched, and the currently searched antenna can be the antenna currently being searched in the second first antenna combination. The second channel quality metric can be the maximum singular value; however, it should be clear that this statement is not intended to limit the first and second channel quality metrics to only the maximum singular value, and they can also be other indicators that can reflect channel quality.

[0074] By constructing an antenna subset containing the current search antenna and all subsequent antennas in the second antenna set under the current search first antenna combination, and calculating the second channel quality metric value corresponding to the antenna subset, a judgment basis is provided for subsequently determining the current search second antenna combination, reducing the probability of unordered search of the second antenna set and improving the efficiency of antenna selection.

[0075] For example, when determining the current search second antenna combination based on the second search order of each antenna in the second antenna set under the current search first antenna combination, the second preset number of antenna selections, and the second channel quality metric, it can be implemented in the following manner, but is not limited to: in response to the second channel quality metric being greater than the third channel quality metric, combining the current search antenna and at least one antenna after the current search antenna into the current search second antenna combination; the third channel quality metric is the maximum value among the channel quality metric between the current search first antenna combination and the previous search second antenna combination and the channel quality metric between the previous search first antenna combination and the previous search second antenna combination; and the number of the current search antenna and at least one antenna after the current search antenna is the preset number of second antenna selections.

[0076] In embodiments of this disclosure, the third channel quality metric can be the maximum singular value. By comparing the second and third channel quality metric values ​​before assembling the receiving antenna combination, only the second antenna combination with the optimal channel quality metric is retained, reducing invalid judgments of low-performance antenna pairings and improving antenna selection efficiency.

[0077] For example, antenna selection may be implemented in, but is not limited to, the following manner: in response to a second channel quality metric being less than or equal to a third channel quality metric, determining the next search second antenna combination in the second antenna set based on a second search order of each antenna in the second antenna set under the current search first antenna combination and a second preset number of antenna selections in the second antenna set.

[0078] In embodiments of this disclosure, the next search second antenna combination can be the next second antenna combination to be searched. The search position can be moved to the next antenna in the second antenna set according to the second search order, with the next antenna serving as the new current search antenna. A new current search second antenna combination can then be determined based on the second preset antenna selection quantity and the second channel quality metric.

[0079] By skipping the current search antenna and moving to the next search antenna when the second channel quality metric is no greater than the third channel quality metric, the efficiency of antenna selection is improved by reducing ineffective antenna combinations on antennas with inferior channel quality.

[0080] For example, when determining the current search antenna selection result as the target antenna selection result in response to the current search antenna selection result satisfying the preset antenna selection conditions, the following methods can be used, but are not limited to: determining a fourth channel quality metric between the current search first antenna combination and the current search second antenna combination; updating the third channel quality metric to the fourth channel quality metric in response to the fourth channel quality metric being greater than the third channel quality metric; and determining the current search first antenna combination and the current search second antenna combination as the target antenna selection result in response to the first channel quality metrics corresponding to all first antenna combinations after the current search first antenna combination being less than or equal to the updated third channel quality metric.

[0081] In embodiments of this disclosure, the fourth channel quality metric can be a maximum singular value. The updated third channel quality metric can be the channel quality metric obtained by replacing the original third channel quality metric with the fourth channel quality metric.

[0082] By dynamically updating the third channel quality metric, the performance limit of the remaining antenna combinations can be determined in advance. The optimal pairing can be locked without traversing all antenna combinations, shortening the antenna search process and improving the efficiency of antenna selection.

[0083] For example, antenna selection may be implemented in, but is not limited to, the following manner: in response to the existence of a target first channel quality metric value greater than the updated third channel quality metric value among the first channel quality metric values ​​corresponding to the first antenna combination after the current search for the first antenna combination, determining the first antenna combination corresponding to the target first channel quality metric value; determining a fifth channel quality metric value between the first antenna combination corresponding to the target first channel quality metric value and at least one second antenna combination in the second antenna set; in response to the fifth channel quality metric value being greater than the updated third channel quality metric value, updating the target antenna selection result to the first antenna combination corresponding to the fifth channel quality metric value and the second antenna combination corresponding to the fifth channel quality metric value.

[0084] In embodiments of this disclosure, the fifth channel quality metric can be the maximum singular value. By evaluating the fifth channel quality metric between the candidate antenna selection result and the second antenna combination when a candidate antenna selection result with a better channel quality metric exists in the subsequent first antenna combination, and updating the target antenna selection result after confirming the better result, the search process retains a verification mechanism for potential better configurations while pruning in advance. This reduces the possibility of missing better antenna selection results due to premature termination of antenna selection, and improves the accuracy of antenna selection results.

[0085] In embodiments of this disclosure, an upper bound on the achievable performance under the current antenna selection can be constructed. The current antenna selection can be a subset of the target antenna selection quantity. A judgment is made based on whether the performance upper bound reaches the currently obtained optimal performance: if the currently obtained optimal performance cannot be reached, the search under the current antenna selection is stopped; otherwise, the search continues under the current antenna selection. In the following embodiments, the process of stopping the search can be described as pruning.

[0086] In embodiments of this disclosure, the aforementioned performance metrics include, but are not limited to, the maximum singular value of the channel submatrix after antenna selection. When used for single-stream transmission that allows for joint beamforming at the transceiver end, the maximum singular value of the channel submatrix after antenna selection is preferred among the aforementioned performance metrics.

[0087] In the embodiments of this disclosure, the antenna selection method can be divided into two steps: antenna selection is performed on one side of the receiving or transmitting end; antenna selection is performed on the other side of the receiving or transmitting end. The aforementioned performance upper bound, that is, the upper bound of the maximum singular value of the channel submatrix, is calculated by fixing the current antenna selection and including all other unselected antennas at the receiving or transmitting end in the maximum singular value of the selected extended matrix.

[0088] In the embodiments of the present disclosure, the above-mentioned current antenna selection is usually a partial result of the target antenna selection quantity. For example, the target antenna selection quantity is to select P=8 antennas from M=32 antennas at the transmitting end, and select Q=4 antennas from N=16 antennas at the receiving end, then the current antenna selection may be: K=4 antennas have been selected at the transmitting end, and L=2 antennas have been selected at the receiving end, that is, the case where K<P and L<Q. At this time, the calculable upper bound is to select all M=32 antennas at the transmitting end and select the current L=2 antennas at the receiving end; or select the current K=4 antennas at the transmitting end and select all N=16 antennas at the receiving end. K=8 antennas have been selected at the transmitting end, and L=2 antennas have been selected at the receiving end, that is, the case where K=P and L<Q. At this time, one calculable upper bound is to select the current K=8 antennas at the transmitting end and select all N=16 antennas at the receiving end. K=4 antennas have been selected at the transmitting end, and L=4 antennas have been selected at the receiving end, that is, the case where K<P and L=Q. At this time, one calculable upper bound is to select all M=32 antennas at the transmitting end and select the current L=4 antennas at the receiving end.

[0089] In the embodiments of the present disclosure, the mathematical basis for this upper bound is: when several rows or several columns are deleted from a matrix, the maximum singular value of the obtained submatrix will not exceed the maximum singular value of the original matrix.

[0090] In the embodiments of the present disclosure, the antenna selection method has the following process: perform antenna selection on one side of the receiving end or the transmitting end. The following process takes the transmitting end as an example, but this process can be used for the receiving end in a dual manner. Perform a full traversal of the transmitting end antenna selection, that is, traverse all combinations of selecting P antennas from M transmitting end antennas. For each of the above combinations, select all the receiving end antennas (that is, ignore the limit of selecting Q antennas, and select all N receiving end antennas), and calculate the maximum singular value of the formed extended matrix as the upper bound of the maximum singular value of this combination. Sort in descending order based on the upper bound of the maximum singular value of each combination.

[0091] In embodiments of this disclosure, antenna selection is performed on the other side of the receiving or transmitting end. The following description uses the receiving end as an example, but this process can be applied dually to the transmitting end. The maximum singular value is initialized to 0. Each of the above-described transmitting antenna combinations is traversed in descending order of the upper bound of the maximum singular value. The current set of transmitting antenna combinations is retrieved and fixed. Under the currently fixed transmitting antenna combination, if the corresponding upper bound of the maximum singular value is not greater than the currently searched maximum singular value, then pruning is performed. (Since the transmitting antenna combinations have been sorted in descending order according to the upper bound of the maximum singular value, a relatively large current maximum singular value can usually be obtained in the early stages of the search. Subsequently, a large number of transmitting antenna combinations and their corresponding receiving branches will be pruned due to insufficient upper bound. Therefore, this descending order can significantly reduce the number of transmitting and receiving line combinations that need to be explicitly calculated for the complete maximum singular value.) If the upper bound of the maximum singular value is greater than the maximum singular value already found, it means that the current transmitting antenna combination still has the potential to generate a better solution, so the depth-first search process for the receiving antenna is entered.

[0092] In the embodiments of this disclosure, all candidate receiving antennas are sorted according to a certain heuristic criterion. A common criterion is to sort the candidate receiving antennas in descending order based on the norm of the column vectors corresponding to the current transmitting antennas. The purpose is to prioritize expanding branches that are more likely to produce larger maximum singular values, so as to obtain larger current maximum singular values ​​as early as possible, thereby enhancing the subsequent pruning effect. Starting from an empty set, receiving antenna selection is performed layer by layer. Each layer indicates whether to add the current candidate receiving antenna to the selected set. At any intermediate node in the depth-first search tree, the current state consists of two parts: the first part is the set of already selected receiving antennas, and the second part is the set of candidate receiving antennas that have not yet been processed. For the current intermediate node, both the "already selected receiving antennas" and "all receiving antennas that may still be selected" are selected simultaneously, and the maximum singular value of the expansion matrix is ​​calculated as the upper bound of the maximum singular value of the current search node.

[0093] In the embodiments of this disclosure, if the upper bound of the maximum singular value of the intermediate node is not greater than the currently searched maximum singular value, the branch is pruned and backtracked to the previous layer. If the upper bound of the intermediate node is greater than the currently searched maximum singular value, the branch is retained and the search continues to the next layer. If the number of currently selected receiving antennas has reached Q, the maximum singular value of the current antenna selection result is calculated; if the maximum singular value is greater than the currently searched maximum singular value, the current maximum singular value is updated, and the corresponding transmitting antenna combination and receiving antenna combination are recorded as the optimal antenna selection result.

[0094] In embodiments of this disclosure, the above process can also be used for antenna selection involving different combinations of transceiver antenna numbers, for example, where the sum of the transceiver antenna numbers (P+Q) is a fixed value. In this scenario, antenna selection combinations with closer transceiver antenna numbers are prioritized (such combinations have a greater probability of obtaining the maximum singular value).
