[0070] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0071] Figure 1 This is one of the flowcharts illustrating the information transmission method provided in the embodiments of this application; Figure 2 This is a second schematic flowchart of the information transmission method provided in the embodiments of this application; Figure 3 This is a schematic diagram of the structure of a terminal provided in an embodiment of this application; Figure 4 This is a schematic diagram of the structure of a network device provided in an embodiment of this application; Figure 5 This is one of the structural schematic diagrams of an information transmission device provided in the embodiments of this application; Figure 6 This is a second schematic diagram of the structure of an information transmission device provided in an embodiment of this application. Detailed Implementation

[0072] To better acquire DL CSI, the UE can report its supported SRS antenna switching capabilities.

[0073] Based on the SRS antenna handover capability reported by the UE, the base station configures one or more SRS resource sets for the UE to perform DL CSI acquisition. Each SRS resource set includes one or more SRS resources. By measuring all SRS resources, the base station can obtain the channel state information of each downlink receiving antenna, thereby guiding downlink scheduling.

[0074] For UEs that support up to 4 receive antennas, the UE's supported SRS antenna handover capability is reported in the following manner: The UE reports the first information (the first information can be a parameter or an information element (IE)). The first information is a candidate value indicated by the UE from multiple candidate values ​​used to indicate the SRS Tx port switching pattern. The first information indicates the combination of SRS Tx port switching patterns supported by the UE (note that the combination of patterns here can be a single pattern or multiple patterns).

[0075] For UEs that support multiple SRS antenna switching modes, the UE should be allowed to report all the SRS antenna switching modes it supports.

[0076] When the maximum number of receive antennas supported by the UE is 4, the candidate values ​​for the SRS Tx port switching pattern corresponding to the first information include all possible combinations of SRS Tx port switching patterns. At this point, the required signaling overhead is acceptable. However, when the number of receive antennas supported by the UE is large, the number of possible combinations of SRS Tx port switching patterns included in the candidate values ​​for the first information will increase, resulting in significant overhead for UE capability reporting. For example, if the SRS antenna switching modules supported by the system include all xTyRs with x <= N and y <= N (where x represents the number of transmit antenna ports / transmit antennas, y represents the number of all or part of the UE's receive antennas / receive antenna ports, and N is a positive integer), then reporting all combinations of SRS antenna switching modes requires N bits.

[0077] Based on the above-mentioned technical problems, this application proposes an information transmission method. This method avoids waste of signaling resources and improves resource utilization by limiting the number of SRS antenna switching mode combinations that can be indicated.

[0078] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0079] Figure 1 This is one of the flowcharts illustrating the information transmission method provided in the embodiments of this application, such as... Figure 1 As shown, this application provides an information transmission method, the execution subject of which can be a UE, such as a mobile phone. The method includes: Step 101: Send SRS antenna switching capability information to the network device.

[0080] The SRS antenna switching capability information includes first information; the first information is used to indicate one or more of the following: The UE does not support the SRS antenna switching modes in the first set; The UE does not support SRS antenna switching; One SRS antenna switching mode supported by the UE in the first set; The first set includes multiple SRS antenna switching modes supported by the UE.

[0081] SRS antenna switching capability information can also be SRS antenna switching capability information.

[0082] The SRS antenna switching mode can also be set to SRS antenna switching mode.

[0083] In some embodiments, the SRS antenna switching mode in the first set includes one or more of the following: The SRS antenna switching modes supported by the system; The SRS antenna switching mode configured on the network device; Preset SRS antenna switching mode.

[0084] Specifically, the SRS antenna switching modes in this first set are all the SRS antenna switching modes supported by the system.

[0085] In some embodiments, the SRS antenna switching modes supported by the system include t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, and t4r8.

[0086] For example, when all the SRS antenna switching modes supported by the system are {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8}, the SRS antenna switching modes in this first set are {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8}.

[0087] The SRS antenna switching modes in this first set may also include SRS antenna switching modes configured by network devices.

[0088] For example, the SRS antenna switching modes configured by the network device include t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, and t4r8. After obtaining the above configuration of the network device, the UE determines the SRS antenna switching modes in the first set as {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8}.

[0089] The SRS antenna switching modes in this first set may also include preset SRS antenna switching modes.

[0090] The preset SRS antenna switching mode can refer to the SRS antenna switching mode predefined in the protocol.

[0091] In some embodiments, the preset SRS antenna switching modes include at least t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, and t4r8; or, The preset SRS antenna switching modes include at least t1r6, t1r8, t2r6, t2r8, and t4r8; or, The preset SRS antenna switching modes include at least t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8, t1r4-t2r4, t1r6-t2r6, and t1r8-t2r8; or, The preset SRS antenna switching modes include at least t1r6, t1r8, t2r6, t2r8, t4r8, t1r6-t2r6, and t1r8-t2r8; or, The preset SRS antenna switching modes include at least t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8, t1r4-t2r4, t1r6-t2r6, t1r8-t2r8-t4r8, t1r8-t2r8, t1r8-t4r8, t2r8-t4r8; or, The preset SRS antenna switching modes include at least t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8, t1r4-t2r4, t1r6-t2r6, and t1r8-t2r8-t4r8.

[0092] It should be noted that the preset SRS antenna switching modes listed above are exemplary and not a limitation on preset SRS antenna switching modes. In actual applications, preset SRS antenna switching modes can be defined as needed, and they will not be listed one by one here.

[0093] In some embodiments, the first set is associated with an information field containing SRS antenna switching capability information; or... The first set is associated with signaling carrying the SRS antenna switching capability information; or, The first set is associated with the information field containing the first information; or, The first set is associated with the signaling carrying the first information.

[0094] Specifically, the first set of information corresponding to different SRS antenna switching capabilities (IE) is different.

[0095] The first set is associated with the signaling carrying the first information, that is, the first set or the SRS antenna switching mode in the first set is associated with the signaling carrying the first information.

[0096] For example, the first set or the SRS antenna switching mode in the first set is associated with the type of signaling carrying the first information.

[0097] The SRS antenna switching modes in the first set corresponding to different signaling types carrying this first information are also different.

[0098] For example, when the SRS antenna switching capability information (first information) is carried through the first IE, the SRS antenna switching modes in the first set are {t1r1, t1r2, t1r4, t2r2, t2r4, t4r4}; when the SRS antenna switching capability information is carried through the second IE information, the SRS antenna switching modes in the first set are {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8}.

[0099] Step 102: Receive SRS configuration information sent by the network device; the SRS configuration information is determined by the network device based on the SRS antenna switching capability information.

[0100] Specifically, after the UE sends SRS antenna switching capability information to the network device, the network device obtains the SRS antenna switching capability information sent by the UE.

[0101] Then, the network device determines the SRS configuration information based on the SRS antenna switching capability information and sends the SRS configuration information to the UE.

[0102] The SRS configuration information is used to indicate the set of SRS resources configured on the network side, and each SRS resource set includes one or more SRS resources.

[0103] Different SRS antenna switching modes correspond to different SRS configuration information.

[0104] Step 103: Send SRS based on the SRS configuration information.

[0105] Specifically, after the UE obtains the SRS configuration information, it sends an SRS based on the SRS configuration information.

[0106] For example, the UE determines the set of SRS resources configured on the network side based on the SRS configuration information, and uses one or more SRS resources in the SRS resource set to send SRS.

[0107] The network-side device obtains the SRS sent by the UE and determines the CSI based on the SRS.

[0108] The information transmission method provided in this application embodiment avoids wasting signaling resources and improves resource utilization by limiting the number of SRS antenna switching mode combinations that can be indicated.

[0109] In some embodiments, the first information is reported as a bitmap.

[0110] For example, S bits are used to indicate the SRS antenna switching modes supported by the UE from S S SRS antenna switching modes, with each bit indicating one SRS antenna switching mode. If a bit is set to "0", it means that the UE supports the SRS antenna switching mode corresponding to that bit; if a bit is set to "1", it means that the UE does not support the SRS antenna switching pattern corresponding to that bit; and vice versa.

[0111] In some embodiments, when the first information is used to indicate multiple SRS antenna switching modes supported by the UE in the first set, the multiple SRS antenna switching modes satisfy one or more of the following conditions: None of the SRS antenna switching modes is a downgraded mode of the other SRS antenna switching modes. The number of receiving antennas is the same for all SRS antenna switching modes. The existence of a third SRS antenna switching mode among the plurality of SRS antenna switching modes makes all other SRS antenna switching modes among the plurality of SRS antenna switching modes a downgraded mode of the third SRS antenna switching mode. The number of transmit antenna ports is the same for all SRS antenna switching modes. The configuration corresponding to any one of the multiple SRS antenna switching modes is not the downgraded configuration corresponding to other SRS antenna switching modes among the multiple SRS antenna switching modes. Among the multiple SRS antenna switching modes, there exists an SRS antenna switching mode such that the configurations corresponding to the other SRS antenna switching modes are all downgraded configurations of it.

[0112] Optionally, the configuration corresponding to the SRS antenna switching mode is the SRS configuration corresponding to the SRS antenna switching mode.

[0113] Optionally, the downgraded configuration of the SRS antenna switching mode, or the downgraded configuration corresponding to the SRS antenna switching mode, can be understood as the configuration corresponding to the downgraded mode of the SRS antenna switching mode. For example, assuming that SRS antenna switching mode t1r2 is a downgraded mode of SRS antenna switching mode t1r4, then the SRS configuration corresponding to SRS antenna switching mode t1r2 is the downgraded configuration corresponding to SRS antenna switching mode t1r4.

[0114] Taking as an example any one of the plurality of SRS antenna switching modes is not a downgraded mode of other SRS antenna switching modes among the plurality of SRS antenna switching modes. Specifically, any one of the plurality of SRS antenna switching modes indicated by the first information may not be a downgraded mode of other SRS antenna switching modes.

[0115] For example, the multiple SRS antenna handover modes supported by the UE in the first set are {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8}. Furthermore, the degradation mode for each SRS antenna handover mode is determined through a predefined method in the protocol, as shown in Table 1.

[0116] Table 1. Mapping Relationship between SRS Antenna Switching Modes and Their Corresponding Degradation Modes Serial Number SRS antenna switching mode Downgrade mode 1 t1r1 none 2 t1r2 t1r1 3 t1r4 t1r1, t1r2 4 t1r6 t1r1, t1r2, t1r4 5 t1r8 t1r1, t1r2, t1r4, t1r6 6 t2r2 t1r1 7 t2r4 t1r1, t1r2, t2r2 8 t2r6 t1r1, t1r2, t2r2, t2r4 9 t2r8 t1r1, t1r2, t1r4, t2r2, t2r4, t2r6 10 t4r4 t1r1, t2r2 11 t4r8 t1r1, t1r2, t2r2, t2r4, t4r4 The first piece of information can indicate one from all or a subset of the following combinations: {t1r1},{t1r2}, {t1r4}, {t1r6}, {t1r8}, {t2r2}, {t2r4}, {t2r6},{t2r8}, {t4r4}, {t4r8}, {t1r4,t2r2}, {t1r4,t2r4}, {t1r6, t2r6}, {t1r6,t2r4}, {t1r6, t2r2},{t1r8,t2r2},{t1r8,t2r4}, {t1r8,t2r6}, {t1r8,t2r8}, {t1r8,t4r4}, {t1r8,t4r8}, {t2r8,t4r8}.

[0117] The number of receiving antennas corresponding to all SRS antenna switching modes indicated by the first information can be the same.

[0118] Based on the above examples, the first piece of information can indicate one from all or a subset of the following combinations: {t1r1},{t1r2}, {t1r4}, {t1r6}, {t1r8}, {t2r2}, {t2r4}, {t2r6},{t2r8}, {t4r4}, {t4r8}, {t1r4,t2r4}, {t1r4,t4r4},{ t2r4, t4r4}, { t1r6, t2r6}, {t1r8, t2r8}, {t1r8, t4r8}, {t2r8, t4r8}, {t1r8, t2r8,t4r8}.

[0119] Among the multiple SRS antenna switching modes indicated by the first information, there exists an SRS antenna switching mode that makes the other SRS antenna switching modes its downgraded modes.

[0120] Based on the above examples, the first piece of information can indicate one from all or a subset of the following combinations: One or more combinations of t1r1, t1r2, t2r2, t2r4, t4r4, t1r4, t1r6, t1r8, t2r6 with t4r8; One or more combinations of {t1r1, t2r2, t1r4, t2r4} with t4r4; One or more combinations of t2r8 from {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6}; One or more combinations of t2r6 from {t1r1, t1r2, t1r4, t1r6, t2r2, t2r4}; One or more combinations of t2r4 from {t1r1, t1r2, t1r4, t2r2}; One or more combinations of t1r1, t1r2 with t2r2 in {t1r1, t1r2}; One or more combinations of t1r1, t1r2, t1r4, t1r6 with t1r8; One or more combinations of t1r1, t1r2, t1r4 with t1r6; One or more combinations of {t1r1, t1r2} with t1r4; The combination of t1r1 and t1r2; {t1r1}; {t1r2}; {t1r4}; {t1r6}; {t1r8}; {t2r2}; {t2r4}; {t2r6}; {t2r8}; {t4r4};

[0121] The number of transmit antenna ports corresponding to all SRS antenna switching modes indicated by the first information can be the same.

[0122] Based on the above examples, the first piece of information indicates one from all or a subset of the following combinations: A combination of one or any number of the following: {t1r1}, {t1r2}, {t1r4}, {t1r6}, {t1r8}; A combination of one or more of {t2r2}, {t2r4}, {t2r6}, {t2r8}; A combination of one or more of {t4r4} and {t4r8}.

[0123] The information transmission method provided in this application further restricts the switching modes of multiple SRS antennas indicated by the first information, thereby further avoiding the waste of signaling resources and improving resource utilization.

[0124] In some embodiments, the SRS antenna switching capability information further includes second information; the second information is used to indicate one or more of the following: The UE does not support the SRS antenna switching mode in the second set; The UE does not support SRS antenna switching; The second set describes one SRS antenna switching mode supported by the UE; The second set describes the multiple SRS antenna switching modes supported by the UE.

[0127] It should be noted that: in this embodiment, the content of the SRS antenna switching modes in the second set can be referred to the content of the SRS antenna switching modes in the first set in the above embodiment, and will not be repeated here.

[0128] The first set can be the same as the second set; the first set can be all or part of the second set; or the second set can be all or part of the first set. The first set can also be completely different from the second set, meaning they have no intersection.

[0129] For example, the second set contains content defined by known protocols, while the first set contains newly added content.

[0130] The information transmission method provided in this application restricts multiple SRS antenna switching modes that can be indicated by first information and second information, thereby avoiding waste of signaling resources, improving resource utilization, and also improving system compatibility.

[0131] In some embodiments, where the first information is used to indicate one or more SRS antenna switching modes supported by the UE in a first set, and the second information is used to indicate one or more SRS antenna switching modes supported by the UE in a second set, all SRS antenna switching modes indicated by the first information and the second information satisfy one or more of the following conditions: None of the SRS antenna switching modes indicated by the first information and the second information is a downgraded mode of any of the other SRS antenna switching modes indicated by the first information and the second information.

Wherein, all SRS antenna switching modes indicated by the first information and the second information include one or more SRS antenna switching modes in the first set indicated by the first information, and one or more SRS antenna switching modes in the second set indicated by the second information.

[0132] Specifically, in this embodiment of the application, when the first information is used to indicate one or more SRS antenna switching modes supported by the UE in the first set, and the second information is used to indicate one or more SRS antenna switching modes supported by the UE in the second set, all SRS antenna switching modes indicated by the first information and the second information satisfy one or more of the following conditions: No single SRS antenna switching mode is a downgraded mode of any other SRS antenna switching mode. All SRS antenna switching modes correspond to the same number of receiving antennas; There exists an SRS antenna switching mode that makes all other SRS antenna switching modes its downgraded mode; All SRS antenna switching modes have the same number of transmit antenna ports.

[0133] It should be noted that in this embodiment, the conditions satisfied by all SRS antenna switching modes indicated by the first information and the second information can be referred to the conditions satisfied by the multiple SRS antenna switching modes indicated by the first information in the above embodiment, and will not be repeated here.

[0134] The information transmission method provided in this application embodiment further restricts signaling resources by using multiple SRS antenna switching modes indicated by the second information, thereby further avoiding waste of signaling resources and improving resource utilization.

[0135] In some embodiments, the UE supports a downgraded mode of the SRS antenna switching mode indicated by the first information.

[0136] Specifically, for any SRS antenna switching mode indicated by the first information, the UE supports the downgrade mode corresponding to that SRS antenna switching mode.

[0137] It should be noted that this degradation mode can also be called degradation configuration. Degradation configuration can be understood as the configuration corresponding to the degradation mode of this SRS antenna switching mode.

[0138] For example, if the first information indicates that the UE supports t1r4, and the downgrade mode corresponding to t1r4 is t1r1, t1r2, it means that the UE supports the SRS configuration corresponding to t1r1, t1r2, and t1r4.

[0139] For example, if the first information indicates that the UE supports t1r8 and t2r8, and the downgrade modes corresponding to t1r8 are t1r1, t1r2, t1r4, and t1r6, and the downgrade modes corresponding to t2r8 are t1r1, t1r2, t1r4, t2r2, t2r4, and t2r6, then it means that the UE supports t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, and t2r8.

[0140] Taking multiple SRS antenna switching patterns as {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8} as an example, assuming the degradation patterns of each pattern are as follows... Figure 1 Examples 1 to 11 show some examples of graphs from which the first parameter indicates one or more of the items: In some embodiments, the SRS antenna switching capability information further includes third information; the third information is used to indicate one or more of the following: The UE supports a downgrade mode for SRS antenna switching mode; The UE does not support the downgrade mode of SRS antenna switching mode; The downgrade mode of the SRS antenna switching mode supported by the UE.

[0141] In some embodiments, when the number of transmit antenna ports corresponding to the first SRS antenna switching mode is not greater than the number of transmit antenna ports corresponding to the second SRS antenna switching mode, and the number of receive antennas corresponding to the first SRS antenna switching mode is not greater than the number of receive antennas corresponding to the second SRS antenna switching mode, the first SRS antenna switching mode is a downgraded mode of the second SRS antenna switching mode; the first SRS antenna switching mode and the second SRS antenna switching mode are any two different SRS antenna switching modes.

[0142] Specifically, if the number of transmitting antenna ports in the first SRS antenna switching mode is not greater than the number of transmitting antenna ports in the second SRS antenna switching mode, and the number of receiving antennas in the first SRS antenna switching mode is not greater than the number of receiving antennas in the second SRS antenna switching mode, then the first SRS antenna switching mode is a downgraded mode of the second SRS antenna switching mode.

[0143] For example, if M is not greater than X and N is not greater than Y, then the SRS antenna switching mode tMrN is a downgraded mode of the SRS antenna switching mode tXrY. Here, M, N, X, and Y are all positive integers.

[0144] In some embodiments, when the number of transmit antenna ports corresponding to the first SRS antenna switching mode is not greater than the number of transmit antenna ports corresponding to the second SRS antenna switching mode, and the number of SRS resources indicated by the SRS configuration information corresponding to the first SRS antenna switching mode is not greater than the number of SRS resources indicated by the SRS configuration information corresponding to the second SRS antenna switching mode, the first SRS antenna switching mode is a downgraded mode of the second SRS antenna switching mode; the first SRS antenna switching mode and the second SRS antenna switching mode are any two different SRS antenna switching modes.

[0145] Specifically, if the number of SRS resources included in the SRS configuration corresponding to the first SRS antenna switching mode is not greater than the number of SRS resources included in the SRS configuration corresponding to the second SRS pattern, and the number of antenna ports corresponding to the SRS resources in the SRS configuration corresponding to the first SRS antenna switching mode is not greater than the number of antenna ports of the SRS resources in the SRS configuration corresponding to the second SRS pattern, then the first SRS antenna switching mode is a downgraded mode of the second SRS antenna switching mode.

[0146] In some embodiments, when the number of transmit antenna ports corresponding to the first SRS antenna switching mode is not greater than the number of transmit antenna ports corresponding to the second SRS antenna switching mode, and the ratio of the number of receive antennas to the number of transmit antenna ports corresponding to the first SRS antenna switching mode is not greater than the ratio of the number of receive antennas to the number of transmit antenna ports corresponding to the second SRS antenna switching mode, the first SRS antenna switching mode is a downgraded mode of the second SRS antenna switching mode; the first SRS antenna switching mode and the second SRS antenna switching mode are any two different SRS antenna switching modes.

[0147] Specifically, if the number of transmitting antenna ports in the first SRS antenna switching mode is not greater than the number of transmitting antenna ports in the second SRS antenna switching mode, and the ratio of the number of receiving antennas to the number of transmitting antenna ports in the first SRS antenna switching mode is not greater than the ratio of the number of receiving antennas to the number of transmitting antenna ports in the second SRS antenna switching mode, then the first SRS antenna switching mode is a downgraded mode of the second SRS antenna switching mode.

[0148] For example, if M is not greater than X and N / M is not greater than Y / X, then the SRS antenna switching mode tMrN is a downgraded mode of the SRS antenna switching mode tXrY. Here, M, N, X, and Y are all positive integers.

[0149] In some embodiments, whether the first SRS antenna switching mode is a downgraded mode of the second SRS antenna switching mode is determined by a preset mapping relationship.

[0150] Specifically, whether the first SRS antenna switching mode is a downgraded mode of the second SRS antenna switching mode is determined by a preset mapping relationship.

[0151] That is, the downgrade mode of each SRS antenna switching mode is a mode predefined by the protocol.

[0152] In some embodiments, the mapping relationship between the SRS antenna switching mode and its corresponding degradation configuration is represented by a preset mapping relationship. For example, it may be one or more of the following items in Table 2: Table 2.
