[0100] To better obtain DL CSI, the UE may report the SRS antenna switching capabilities it supports.

[0101] The base station configures one or more SRS resource sets for the UE to acquire DL CSI based on the SRS antenna switching capability reported by the UE, where each SRS resource set includes one or more SRS resources. By measuring all SRS resources, the base station obtains channel state information for each downlink receive antenna and further guides downlink scheduling.

[0102] For a UE that supports up to four receive antennas, the SRS antenna switching capability supported by the UE is reported using the following method: The UE reports first information (the first information may be one parameter or one information element (IE Information Element)), which indicates one candidate value from multiple candidate values ​​for the UE to indicate an SRS Tx port switching pattern, and which indicates a combination of SRS Tx port switching patterns supported by the UE (note that the mode combination here may include only one mode or multiple modes).

[0103] For a UE that supports multiple SRS antenna switching modes, the UE should be allowed to report all SRS antenna switching modes that it supports.

[0104] When the maximum number of receive antennas supported by the UE is four, the candidate values ​​for indicating the SRS Tx port switching pattern corresponding to the first information include all possible combinations of SRS Tx port switching patterns, and the required signaling overhead is still within an acceptable range. However, when the number of receive antennas supported by the UE is large, the candidate values ​​for indicating the SRS Tx port switching pattern corresponding to the first information include all possible combinations of SRS Tx port switching patterns, which increases the overhead for reporting UE capabilities. For example, if the SRS antenna switching modules supported by the system include all xTyR (where x<=N, y<=N) (where x represents the number of transmit antenna ports / transmit antennas, y represents the number of all or some of the receive antennas / receive antenna ports of the UE, and N is a positive integer), N bits are required to report all SRS antenna switching mode combinations.

[0105] Based on the above technical problems, an embodiment of the present disclosure provides an information transmission method, which can avoid wasting signaling resources and improve resource utilization by limiting the number of combinations of SRS antenna switching modes that can be instructed.

[0106] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Of course, the described embodiments are not all embodiments, but only some embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments that a person skilled in the art can obtain without creative work fall within the scope of protection of the present disclosure.

[0107] 1 is a flowchart of an information transmission method according to an embodiment of the present disclosure. As shown in FIG. 1, an embodiment of the present disclosure provides an information transmission method, the execution body of which may be a UE such as a mobile phone, etc. The method includes steps 101, 102, and 103. In step 101, SRS antenna switching capability information is sent to a network device.

[0108] wherein the SRS antenna switching capability information includes first information, and the first information is The UE does not support the SRS antenna switching mode in the first set; and The UE does not support SRS antenna switching, and One SRS antenna switching mode supported by the UE in the first set; and a plurality of SRS antenna switching modes supported by the UE in the first set.

[0109] The SRS antenna switching capability information may be SRS antenna port switching capability information.

[0110] The SRS antenna switching mode may be an SRS antenna port switching mode.

[0111] In some embodiments, the SRS antenna switching mode in the first set is: SRS antenna switching modes supported by the system; The SRS antenna switching mode set by the network device, and a preset SRS antenna switching mode.

[0112] Specifically, the SRS antenna switching modes in the first set are all SRS antenna switching modes supported by the system.

[0113] In some embodiments, SRS antenna switching modes supported by the system include t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, and t4r8.

[0114] For example, if all 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 the first set are {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8}.

[0115] The SRS antenna switching mode in the first set may further include an SRS antenna switching mode set by the network device.

[0116] For example, the SRS antenna switching modes set by the network equipment include t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4 and t4r8, and after obtaining the above settings of the network equipment, the UE determines that the SRS antenna switching modes in the first set are {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8}.

[0117] The SRS antenna switching modes in the first set may further include a preset SRS antenna switching mode.

[0118] A preset SRS antenna switching mode may refer to an SRS antenna switching mode predefined by a protocol.

[0119] 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.

[0120] It should be noted that the preset SRS antenna switching modes listed above are merely examples and are not intended to limit the preset SRS antenna switching modes. In actual applications, the preset SRS antenna switching modes can be defined as needed, and will not be listed here one by one.

[0121] In some embodiments, the first set has an association with an information domain that includes SRS antenna port switching capability information; or The first set has an association with signaling carrying the SRS antenna port switching capability information; or the first set has an association relationship with an information domain that includes the first information; or The first set includes signaling and association relationships that carry the first information.

[0122] Specifically, the first sets corresponding to different SRS antenna port switching capability information IEs are different.

[0123] The first set has an association relationship with the signaling carrying the first information, i.e., the first set or the SRS antenna switching mode in the first set is related to the signaling carrying the first information.

[0124] For example, the first set, or an SRS antenna switching mode in the first set, is related to the type of signaling that carries the first information.

[0125] The SRS antenna switching modes in the first set corresponding to different types of signaling carrying the first information are also different.

[0126] For example, when the SRS antenna switching capability information (first information) is carried by the first IE, the SRS antenna switching mode in the first set is {t1r1, t1r2, t1r4, t2r2, t2r4, t4r4}, and when the SRS antenna switching capability information is carried by the second IE information, the SRS antenna switching mode in the first set is {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8}.

[0127] In step 102, SRS configuration information transmitted by the network device is received, and the SRS configuration information is determined by the network device based on the SRS antenna switching capability information.

[0128] Specifically, after the UE transmits the SRS antenna switching capability information to the network device, the network device obtains the SRS antenna switching capability information transmitted by the UE.

[0129] Then, the network device determines SRS configuration information based on the SRS antenna switching capability information, and sends the SRS configuration information to the UE.

[0130] Here, the SRS configuration information indicates SRS resource sets configured by the network side, and each SRS resource set includes one or more SRS resources.

[0131] The SRS setting information corresponding to different SRS antenna switching modes is different.

[0132] In step 103, the SRS is transmitted based on the SRS setting information.

[0133] Specifically, after obtaining the SRS configuration information, the UE transmits the SRS based on the SRS configuration information.

[0134] For example, the UE determines an SRS resource set configured by the network side based on the SRS configuration information, and transmits the SRS using one or more SRS resources in the SRS resource set.

[0135] The network side device acquires the SRS transmitted by the UE and determines the CSI based on the SRS.

[0136] The information transmission method according to the embodiment of the present disclosure can avoid wasting signaling resources and improve resource utilization by limiting the number of combinations of SRS antenna switching modes that can be instructed.

[0137] In some embodiments, the first information is reported in the form of a bitmap.

[0138] For example, S bits are used to indicate the SRS antenna switching modes supported by the UE from S SRS antenna switching modes, and each bit indicates one SRS antenna switching mode. When a bit is set to "0", it indicates that the UE supports the SRS antenna switching mode corresponding to the bit, and when a bit is set to "1", it indicates that the UE does not support the SRS antenna switching pattern corresponding to the bit, and vice versa.

[0139] In some embodiments, when the first information is used to indicate multiple SRS antenna switching modes supported by the UE in a first set, the multiple SRS antenna switching modes include: any one of the plurality of SRS antenna switching modes is not a downgrade mode of another SRS antenna switching mode of the plurality of SRS antenna switching modes; and The number of receiving antennas corresponding to all of the plurality of SRS antenna switching modes is the same; and the plurality of SRS antenna switching modes includes one SRS antenna switching mode such that all other SRS antenna switching modes among the plurality of SRS antenna switching modes are downgrade modes thereof; the number of transmit antenna ports corresponding to all of the SRS antenna switching modes among the plurality of SRS antenna switching modes is the same; and A setting corresponding to any one of the plurality of SRS antenna switching modes is not a downgrade setting corresponding to another SRS antenna switching mode of the plurality of SRS antenna switching modes; The plurality of SRS antenna switching modes satisfy one or more of the following conditions: there is one SRS antenna switching mode such that all settings corresponding to other SRS antenna switching modes among the plurality of SRS antenna switching modes are downgraded settings thereof.

[0140] Optionally, the setting corresponding to the SRS antenna switching mode is the SRS setting corresponding to the SRS antenna switching mode.

[0141] Optionally, a downgrade setting of an SRS antenna switching mode or a downgrade setting corresponding to an SRS antenna switching mode may be understood as a setting corresponding to a downgrade mode of the SRS antenna switching mode. For example, assuming that SRS antenna switching mode t1r2 is a downgrade mode of SRS antenna switching mode t1r4, the SRS setting corresponding to SRS antenna switching mode t1r2 is a downgrade setting corresponding to SRS antenna switching mode t1r4.

[0142] For example, one of the plurality of SRS antenna switching modes may not be a downgrade mode of another of the plurality of SRS antenna switching modes. Specifically, one of the plurality of SRS antenna switching modes indicated by the first information may not be a downgrade mode of another of the plurality of SRS antenna switching modes.

[0143] For example, the multiple SRS antenna switching modes supported by the UE in the first set are {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8}, and the downgrade mode of each SRS antenna switching mode is determined according to a predefined manner by the protocol, as shown in Table 1.

[0144] [Table 1]

[0145] The first information may indicate one of all or a subset of the following combinations: {t1r1}, {t1r2}, {t1r4}, {t1r6}, {t1r8}, {t2r2}, {t2r4}, {t2r6}, {t2r8}, {t4r4}, {t4r8}, {t1r4, t2r2}, {t1r4, t2r4}, {t1r6, t2r 6}, {t1r6, t2r4}, {t1r6, t2r2}, {t1r8, t2r2}, {t1r8, t2r4}, {t1r8, t2r6}, {t1r8, t2r8}, {t1r8, t4r4}, {t1r8, t4r8}, {t2r8, t4r8}.

[0146] The number of receiving antennas corresponding to all of the SRS antenna switching modes among the plurality of SRS antenna switching modes indicated by the first information may be the same.

[0147] Based on the above example, the first information may indicate one of 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}.

[0148] Among the plurality of SRS antenna switching modes indicated by the first information, there is one SRS antenna switching mode such that all of the other SRS antenna switching modes are downgrade modes thereof.

[0149] Based on the above example, the first piece of information is A combination of one or more of {t1r1, t1r2, t2r2, t2r4, t4r4, t1r4, t1r6, t1r8, t2r6} with t4r8; A combination of one or more of {t1r1, t2r2, t1r4, t2r4} with t4r4; A combination of one or more of {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6} with t2r8; A combination of one or more of {t1r1, t1r2, t1r4, t1r6, t2r2, t2r4} with t2r6; A combination of one or more of {t1r1, t1r2, t1r4, t2r2} with t2r4; A combination of one or more of {t1r1, t1r2} with t2r2; A combination of one or more of {t1r1, t1r2, t1r4, t1r6} with t1r8; A combination of one or more of {t1r1, t1r2, t1r4} with t1r6; A combination of one or more of {t1r1, t1r2} with t1r4; The combination of t1r1 and t1r2, It can indicate one from all or a subset of {t1r1}, {t1r2}, {t1r4}, {t1r6}, {t1r8}, {t2r2}, {t2r4}, {t2r6}, {t2r8}, {t4r4}, and {t4r8}.

[0150] The number of transmit antenna ports corresponding to all of the SRS antenna switching modes among the plurality of SRS antenna switching modes indicated by the first information may be the same.

[0151] Based on the above example, the first piece of information is One or any combination of {t1r1}, {t1r2}, {t1r4}, {t1r6}, and {t1r8}; One or more combinations of {t2r2}, {t2r4}, {t2r6}, {t2r8}; {t4r4}, {t4r8}, and one of all or a subset of.

[0152] The information transmission method according to an embodiment of the present disclosure can further avoid wasting signaling resources and improve resource utilization by further restricting the multiple SRS antenna switching modes indicated by the first information.

[0153] In some embodiments, the SRS antenna switching capability information further includes second information, the second information being: The UE does not support an SRS antenna switching mode in the second set; and The UE does not support SRS antenna switching; One SRS antenna switching mode supported by the UE in a second set; and and a second set of SRS antenna switching modes supported by the UE.

[0154] Specifically, in an embodiment of the present disclosure, the SRS antenna switching capability information may include second information, and the second information may be: The UE does not support the SRS antenna switching mode in the second set; and The UE does not support SRS antenna switching, and One SRS antenna switching mode supported by the UE in the second set; and and a plurality of SRS antenna switching modes supported by the UE in the second set.

[0155] Here, the SRS antenna switching mode in the second set is: SRS antenna switching modes supported by the system; The SRS antenna switching mode set by the network device, and a preset SRS antenna switching mode.

[0156] In addition, in the embodiment of the present disclosure, the contents included in the SRS antenna switching mode in the second set can refer to the contents included in the SRS antenna switching mode in the first set in the above embodiment, and will not be described further here.

[0157] The first set may be the same as the second set, the first set may be all or a portion of the second set, or the second set may be all or a portion of the first set. The first set may be completely different from the second set, i.e., there may be no intersection between the two.

[0158] For example, the second set is content defined by a known protocol, the first set is new content, and so on.

[0159] The information transmission method according to an embodiment of the present disclosure limits the number of SRS antenna switching modes that can be instructed by the first information and the second information, thereby avoiding waste of signaling resources, improving resource utilization, and also improving system compatibility.

[0160] In some embodiments, when the first information is used to indicate one or more SRS antenna switching modes supported by a 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 are: any one of all SRS antenna switching modes indicated by the first information and the second information is not a downgrade mode of another SRS antenna switching mode of all SRS antenna switching modes indicated by the first information and the second information; and the number of receiving antennas corresponding to all SRS antenna switching modes among all SRS antenna switching modes indicated by the first information and the second information is the same; and Among all SRS antenna switching modes indicated by the first information and the second information, there exists one SRS antenna switching mode such that all other SRS antenna switching modes indicated by the first information and the second information are downgrade modes thereof; the number of transmit antenna ports corresponding to all SRS antenna switching modes among all SRS antenna switching modes indicated by the first information and the second information is the same; and Here, all of the 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.

[0161] Specifically, in an embodiment of the present disclosure, 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 the SRS antenna switching modes indicated by the first information and the second information are: Any one of the SRS antenna switching modes is not a downgrade mode of another SRS antenna switching mode, The number of receiving antennas corresponding to all SRS antenna switching modes is the same, There is one SRS antenna switching mode such that any other SRS antenna switching mode is a downgrade mode thereof; and The number of transmit antenna ports corresponding to all SRS antenna switching modes is the same.

[0162] In addition, in the embodiment of the present disclosure, the conditions that all SRS antenna switching modes indicated by the first information and the second information must satisfy can refer to the conditions that multiple SRS antenna switching modes indicated by the first information in the above embodiment must satisfy, and will not be described further here.

[0163] The information transmission method according to an embodiment of the present disclosure can further avoid wasting signaling resources and improve resource utilization by further restricting the multiple SRS antenna switching modes indicated by the second information.

[0164] In some embodiments, the UE supports a downgrade mode of the SRS antenna switching mode indicated by the first information.

[0165] Specifically, for any one SRS antenna switching mode indicated by the first information, the UE supports a downgrade mode corresponding to the SRS antenna switching mode.

[0166] Note that the downgrade mode may also be called a downgrading configuration, and the downgrading configuration may be understood as a setting corresponding to the downgrading mode corresponding to the SRS antenna switching mode in this section.

[0167] For example, if the first information indicates that the UE supports t1r4, and the downgrade modes corresponding to t1r4 are t1r1 and t1r2, it means that the UE supports SRS configurations corresponding to t1r1, t1r2, and t1r4.

[0168] Also, 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, t1r6, and the downgrade modes corresponding to t2r8 are t1r1, t1r2, t1r4, t2r2, t2r4, t2r6, it means that the UE supports t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, and t2r8.

[0169] Taking the multiple SRS antenna switching patterns as {t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, t2r6, t2r8, t4r4, t4r8} as an example, assuming that the downgrade patterns for each pattern are as shown in Examples 1 to 11 in Table 1, some examples in which the first parameter indicates one or more of these patterns are as follows: In some embodiments, the SRS antenna switching capability information further includes third information, the third information being: The UE supports a downgrade mode of an SRS antenna switching mode; and The UE does not support a downgrade mode of the SRS antenna switching mode; and a downgrade mode of the SRS antenna switching mode supported by the UE.

[0170] In some embodiments, if the number of transmit antenna ports corresponding to a first SRS antenna switching mode is less than or equal to the number of transmit antenna ports corresponding to a second SRS antenna switching mode, and the number of receive antennas corresponding to the first SRS antenna switching mode is less than or equal to the number of receive antennas corresponding to the second SRS antenna switching mode, the first SRS antenna switching mode is a downgrade mode of the second SRS antenna switching mode, and the first SRS antenna port switching mode and the second SRS antenna port switching mode are any two different SRS antenna port switching modes.

[0171] Specifically, if the number of transmitting antenna ports in the first SRS antenna switching mode is less than or equal to 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 less than or equal to the number of receiving antennas in the second SRS antenna switching mode, the first SRS antenna switching mode is a downgraded mode of the second SRS antenna switching mode.

[0172] For example, if M is less than or equal to X and N is less than or equal to Y, the SRS antenna switching mode tMrN is a downgraded mode of the SRS antenna switching mode tXrY, where M, N, X, and Y are all positive integers.

[0173] In some embodiments, if the number of transmit antenna ports corresponding to a first SRS antenna switching mode is less than or equal to the number of transmit antenna ports corresponding to a 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 less than or equal to 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 downgrade mode of the second SRS antenna switching mode, and the first SRS antenna port switching mode and the second SRS antenna port switching mode are any two different SRS antenna port switching modes.

[0174] Specifically, if the number of SRS resources included in the SRS setting corresponding to the first SRS antenna switching mode is less than or equal to the number of SRS resources included in the SRS setting corresponding to the second SRS pattern, and the number of antenna ports corresponding to the SRS resources in the SRS setting corresponding to the first SRS antenna switching mode is less than or equal to the number of antenna ports of the SRS resources in the SRS setting corresponding to the second SRS pattern, the first SRS antenna switching mode is a downgrade mode of the second SRS antenna switching mode.

[0175] In some embodiments, if the number of transmit antenna ports corresponding to a first SRS antenna switching mode is less than or equal to the number of transmit antenna ports corresponding to a 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 less than or equal to 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 downgrade mode of the second SRS antenna switching mode, and the first SRS antenna port switching mode and the second SRS antenna port switching mode are any two different SRS antenna port switching modes.

[0176] Specifically, if the number of transmitting antenna ports in the first SRS antenna switching mode is less than or equal to 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 less than or equal to the ratio of the number of receiving antennas to the number of transmitting antenna ports in the second SRS antenna switching mode, the first SRS antenna switching mode is a downgraded mode of the second SRS antenna switching mode.

[0177] For example, if M is less than or equal to X and N / M is less than or equal to Y / X, then SRS antenna switching mode tMrN is a downgraded mode of SRS antenna switching mode tXrY, where M, N, X, and Y are all positive integers.

[0178] In some embodiments, whether the first SRS antenna switching mode is a downgrade mode of the second SRS antenna switching mode is determined by a preset mapping relationship.

[0179] Specifically, whether the first SRS antenna switching mode is a downgrade mode of the second SRS antenna switching mode is determined by a preset mapping relationship.

[0180] That is, the downgrade mode of each SRS antenna switching mode is a mode predefined by the protocol.

[0181] In some embodiments, the mapping relationship between the SRS antenna switching mode and the corresponding downgrade setting is represented by a preset mapping relationship, such as one or more items in Table 2 below.

[0182] [Table 2]

[0183] In some embodiments, the preset mapping relationship is: The downgrade modes corresponding to the SRS antenna port switching mode t1r6 include t1r1, t1r2, and t1r4; The downgrade modes corresponding to the SRS antenna switching mode t1r8 include t1r1, t1r2, t1r4, and t1r6; The downgrade modes corresponding to the SRS antenna switching mode t2r6 include t1r1, t1r2, t2r2, and t2r4; The downgrade modes corresponding to the SRS antenna switching mode t2r8 include t1r1, t1r2, t1r4, t2r2, t2r4, and t2r6; The downgrade modes corresponding to the SRS antenna switching mode t4r8 include t1r1, t1r2, t2r2, t2r4, and t4r4; The downgrade modes corresponding to the SRS antenna switching mode t2r2 include t1r1 and t1r2, The downgrade modes corresponding to the SRS antenna switching mode t2r4 include t1r1, t1r2, t1r4, and t2r2; The downgrade modes corresponding to the SRS antenna switching mode t2r6 include t1r1, t1r2, t1r4, t1r6, t2r2, and t2r4; The downgrade modes corresponding to the SRS antenna switching mode t2r8 include t1r1, t1r2, t1r4, t1r6, t1r8, t2r2, t2r4, and t2r6; The downgrade modes corresponding to the SRS antenna switching mode t4r4 include t1r1, t2r2, t1r4, and t2r4; The downgrade modes corresponding to the SRS antenna switching mode t4r8 include at least one of t1r1, t1r2, t2r2, t2r4, t4r4, t1r4, t1r6, t1r8, t2r6, and t2r8.

[0184] The information transmission method according to the embodiment of the present disclosure can avoid wasting signaling resources and improve resource utilization by limiting the number of combinations of SRS antenna switching modes that can be instructed.

[0185] 2 is a second flowchart of an information transmission method according to an embodiment of the present disclosure. As shown in FIG. 2, an embodiment of the present disclosure provides an information transmission method, the execution body of which may be a network device such as a base station, etc. The method includes steps 201, 202, and 203.

[0186] In step 201, obtain the SRS antenna switching capability information transmitted by the UE.

[0187] wherein the SRS antenna switching capability information includes first information, and the first information is The UE does not support an SRS antenna switching mode in the first set; and The UE does not support SRS antenna switching; One SRS antenna switching mode supported by the UE in a first set; and a plurality of SRS antenna switching modes supported by the UE in the first set.

[0188] Specifically, the UE first transmits SRS configuration information to the network device, and the network device then receives the SRS antenna switching capability information transmitted by the UE.

[0189] Here, the description of the first set may refer to the above-mentioned method embodiment in which the execution body is a UE, and will not be further described here.

[0190] In step 202, SRS configuration information is determined based on the SRS antenna switching capability information.

[0191] Specifically, after the network device receives the SRS antenna switching capability information transmitted by the UE, it determines the SRS configuration information based on the SRS antenna switching capability information.

[0192] In step 203, the SRS configuration information is sent to the UE.

[0193] Specifically, after determining the SRS configuration information, the network device sends the SRS configuration information to the UE.

[0194] After obtaining the SRS configuration information, the UE transmits an SRS based on the SRS configuration information.

[0195] For example, the UE determines an SRS resource set configured by the network side based on the SRS configuration information, and transmits the SRS using one or more SRS resources in the SRS resource set.

[0196] The network side device acquires the SRS transmitted by the UE and determines the CSI based on the SRS.

[0197] The information transmission method according to the embodiment of the present disclosure can avoid wasting signaling resources and improve resource utilization by limiting the number of combinations of SRS antenna switching modes that can be instructed.

[0198] In some embodiments, determining SRS configuration information based on the SRS antenna switching capability information includes: Determining the SRS configuration information based on the first information.

[0199] In some embodiments, determining the SRS configuration information based on the first information includes: When the first information is used to indicate SRS antenna switching modes supported by the UE in a first set, determining the SRS configuration information based on one or more SRS antenna switching modes indicated by the first information includes:

[0200] Specifically, the SRS setting information is SRS setting information corresponding to one SRS antenna switching mode out of one or more SRS antenna switching modes indicated by the first information.
