[0159] The SRS resource is a resource required for configuring an SRS, one SRS resource can correspond to one SRS, the network device can send the first information to the terminal to indicate that the first SRS resource is used for multiple purposes, and the terminal sends the SRS corresponding to the first SRS resource to the network device according to the first information.

That is, the first information transmitted by the network device to the terminal can indicate the first SRS resource set in which the first SRS resource is located or / and indicate the first SRS resource, so as to facilitate the determination of the first SRS resource set or / and the first SRS resource. It should be noted that if the first information indicates the first SRS resource set in which the first SRS resource is located, the first SRS resource is at least part of the SRS resources in the first SRS resource set, and the first SRS resource is specifically which SRS resources in the first SRS resource set, it can be determined in various ways, for example, the first SRS resource can be determined from the first SRS resource set according to the protocol, or the first SRS resource in the first SRS resource set can be indicated by signaling.

[0163] As an example, the first information can be carried by a signaling for indicating an SRS resource set, the signaling for indicating an SRS resource set indicates the first SRS resource set in which the first SRS resource is located, i.e., in which SRS resources the first SRS resource is located, wherein the first SRS resource set can be one or more, and the first SRS resource can be one or more. The second information can also be carried by a signaling for indicating the first SRS resource, the signaling for indicating the first SRS resource is used to indicate which SRS resources the first SRS resource is, and the first SRS resource can be one or more. The second information can also be carried by a signaling for indicating an SRS resource set and the first SRS resource, at this time, the first information can indicate which SRS resources in which SRS resource set the first SRS resource is, wherein the first SRS resource set can be one or more, and the first SRS resource can be one or more.

[0164] Optionally, the first SRS resource includes all or part of the SRS resources in the SRS resource set configured for the first use type, and the first information is further used to indicate that all or part of the SRS resources in the SRS resource set configured for the first use type are also used for the second use, the first use type corresponds to the first use, the first use and the second use are different, and the second use corresponds to the second use type.

[0165] That is, in the embodiment, the first SRS resource can include all SRS resources in the SRS resource set configured as the first use type, and the first information can indicate that all SRS resources in the SRS resource set configured as the first use type are also used for the second use. Alternatively, the first SRS resource can include part of SRS resources in the SRS resource set configured as the first use type, and the first information can indicate that part of SRS resources in the SRS resource set configured as the first use type are also used for the second use. The SRS resource set configured as the first use type can be understood as that the SRS resource set can be used for the first use, and in addition, the first information indicates that the SRS resource set can also be used for the second use, so that all or part of SRS resources in the SRS resource set configured as the first use type can be used for the first use and the second use.

[0166] Optionally, the first SRS resource includes all or part of SRS resources in the SRS resource set configured as the first use type and of a specific time domain type, and the first information includes fifth indication information, the fifth indication information being used to indicate that all or part of SRS resources in the SRS resource set configured as the first use type and of the specific time domain type are also used for the second use.

[0167] That is, in the embodiment, the first SRS resource includes all SRS resources in the SRS resource set configured as the first use type and of a specific time domain type, and the first information can indicate that all SRS resources in the SRS resource set configured as the first use type and of the specific time domain type are also used for the second use. The first SRS resource includes part of SRS resources in the SRS resource set configured as the first use type and of the specific time domain type, and the first information can also indicate that part of SRS resources in the SRS resource set configured as the first use type and of the specific time domain type are also used for the second use. So, all or part of SRS resources in the SRS resource set configured as the first use type can be used for the first use and the second use.

[0168] Optionally, the first information is carried by first use signaling, the first use signaling being used to indicate the use of the first SRS resource set, the first SRS resource set being an SRS resource set including at least one SRS resource in the first SRS resource, and the first use signaling indicating multiple uses.

[0169] That is, in the embodiment, the first information can also be carried by the first use signaling, the first use signaling can indicate the use of the first SRS resource set, the first use signaling indicating multiple uses, and the first SRS resource set including at least one SRS resource in the first SRS resource. It can be understood that the first use signaling can indicate multiple uses of at least one SRS resource in the first SRS resource.

[0170] Optionally, the SRS resource set configured as the first usage type is an SRS resource set configured with usage signaling as the first usage type. For example, in a 3GPP (3rd Generation Partnership Project) NR (new Radio) system, a network device can configure one or more SRS resource sets for a terminal. The configuration information of each SRS resource set includes usage signaling. The usage signaling can be configured as “codebook”, “nonCodebook”, “antennaSwitching” or “beamManagement”. When the usage signaling is configured as “codebook”, the SRS resource set can be used for CSI (channel state information) acquisition of codebook-based PUSCH. When the usage signaling is configured as “nonCodebook”, the SRS resource set can be used for CSI acquisition of non-codebook-based PUSCH. When the usage signaling is configured as “antennaSwitching”, the SRS resource set can be used for downlink CSI acquisition. When the usage signaling is configured as “beamManagement”, the SRS resource set can be used for uplink beam management. The configuration restrictions of SRS resource sets with different usages are different.

[0171] Optionally, the time domain type of the first SRS resource is aperiodic, semi-persistent or periodic.

[0172] In the 3GPP NR protocol, there are three time domain types. When the time domain type (resourceType) of an SRS resource is periodic, the terminal periodically transmits SRS based on the configuration information of the SRS resource. When the time domain type of an SRS resource is aperiodic, the terminal transmits SRS based on the trigger information of the SRS resource (only after receiving the trigger signaling). When the time domain type of an SRS resource is semi-persistent, the terminal periodically transmits SRS based on the activation signaling of the SRS resource until receiving the deactivation signaling. In the present embodiment, the time domain type of the first SRS resource for multiple usages can be aperiodic, semi-persistent or periodic.

[0173] Optionally, the first SRS resource includes a specific SRS resource in the SRS resource set configured as the first usage type, and the first information is used to indicate that the specific SRS resource in the SRS resource set configured as the first usage type is also used for the second usage.

[0174] That is, when the first SRS resource includes part of the SRS resource set configured as the first use type, the first SRS resource can include a specific SRS resource in the SRS resource set configured as the first use type, and the first information can indicate that the specific SRS resource in the SRS resource set configured as the first use type is also used for the second use, that is, the specific SRS resource in the SRS resource set configured as the first use type can be used for the first use and the second use.

[0175] Optionally, the first SRS resource includes a specific SRS resource in the SRS resource set configured as the first use type and of a specific time domain type, and the first information is used to indicate that the specific SRS resource in the SRS resource set configured as the first use type and of the specific time domain type is also used for the second use.

[0176] That is, in the embodiment, the specific SRS resource in the SRS resource set configured as the first use type and of the specific time domain type is also used for the second use, so that the requirements of the first use and the second use of the specific SRS resource can be met.

[0177] Optionally, the specific SRS resource includes at least one of the following:

[0178] the SRS resource indicated by the first information;

[0179] the first s SRS resources with the lowest number in the SRS resource set configured as the first use type, where s is a positive integer;

[0180] the first m SRS resources with the earliest transmission time in the SRS resource set configured as the first use type, where m is a positive integer;

[0181] the SRS resource in the specific SRS resource set in the SRS resource set configured as the first use type;

[0182] the SRS resource in the SRS resource set configured as the first use type and also configured in the second SRS resource set, the second SRS resource set being the SRS resource set configured as the second use type, and the second use type corresponding to the second use;

[0183] the first k SRS resources with the lowest number in the SRS resource set configured as the first use type and of the specific time domain type, where k is a positive integer;

[0184] the first n SRS resources with the earliest transmission time in the SRS resource set configured as the first use type and of the specific time domain type, where n is a positive integer;

[0185] SRS resources in a particular SRS resource set in the SRS resource set configured as the first usage type and of the particular time domain type;

[0186] SRS resources in the SRS resource set configured as the first usage type and of the particular time domain type that are also configured in the second SRS resource set, the second usage type corresponding to the second usage.

[0187] In the embodiment, the particular resource can be indicated by the first information, and it should be noted that the particular SRS resource can also be indicated by the first signaling sent by the network device to the terminal, and the first information can be carried in the first signaling.

[0188] In addition, when the first information is used to indicate information that the particular SRS resource in the SRS resource set configured as the first usage type is also used for the second usage, the particular SRS resource in the SRS resource set configured as the first usage type includes at least one of the following: the first s SRS resources in the SRS resource set configured as the first usage type in terms of the lowest number, the first m SRS resources in the SRS resource set configured as the first usage type in terms of the earliest transmission time, the SRS resources in the particular SRS resource set in the SRS resource set configured as the first usage type, and the SRS resources in the SRS resource set configured as the first usage type that are also configured in the second SRS resource set.

[0189] When the first information is used to indicate information that the particular SRS resource in the SRS resource set configured as the first usage type and of the particular time domain type is also used for the second usage, the particular SRS resource in the SRS resource set configured as the first usage type and of the particular time domain type includes at least one of the following: the first k SRS resources in the SRS resource set configured as the first usage type and of the particular time domain type in terms of the lowest number, the first n SRS resources in the SRS resource set configured as the first usage type and of the particular time domain type in terms of the earliest transmission time, the SRS resources in the particular SRS resource set in the SRS resource set configured as the first usage type and of the particular time domain type, and the SRS resources in the SRS resource set configured as the first usage type and of the particular time domain type that are also configured in the second SRS resource set.

[0190] In the embodiment, the particular resource can be determined through the above-mentioned multiple ways, thereby improving the flexibility of the particular resource.

[0191] Optionally, the particular SRS resource set is one of the following:

[0192] the SRS resource set indicated by the first information;

[0193] a first k SRS resource sets in a SRS resource set configured as the first usage type, where k is a positive integer;

[0194] a first n SRS resource sets in a SRS resource set configured as the first usage type, where n is a positive integer;

[0195] a first t SRS resource sets in a SRS resource set configured as the first usage type and of a specific time domain type, where t is a positive integer;

[0196] a first r SRS resource sets in a SRS resource set configured as the first usage type and of a specific time domain type, where r is a positive integer.

[0197] In this embodiment, the first information can indicate the specific SRS resource set, and it should be noted that the network device can also indicate the specific SRS resource set to the terminal through second signaling, and the first information can be carried in the second signaling. In this embodiment, the specific resource set can be determined through the above-mentioned multiple ways, thereby improving the flexibility of the specific resource set.

[0198] Optionally, before sending the SRS corresponding to the first SRS resource to the network device, the method further includes: receiving configuration information of a first SRS resource set and a second SRS resource set sent by the network device, the second SRS resource set being a second SRS resource set configured as a second usage type, and the second usage type corresponding to a second usage.

[0199] If the configuration information indicates that the transmission time of the first SRS resource set and the transmission time of the second SRS resource set overlap in time, it is determined that the configuration information is incorrect information.

[0200] That is, the network device can configure the terminal with the first SRS resource set and the second SRS resource set of the second usage type, and the network device can send the terminal with the configuration information of the first SRS resource set and the second SRS resource set. If it is determined according to the configuration information that the transmission time of the first SRS resource set and the transmission time of the second SRS resource set overlap in time, the terminal considers it to be an incorrect configuration, which facilitates the detection of the terminal on the configuration and improves the transmission stability.

[0201] Optionally, the first usage includes at least one of the following:

[0202] downlink channel state information (CSI) acquisition;

[0203] uplink CSI acquisition;

[0204] codebook-based physical shared channel (PUSCH) CSI acquisition;

[0205] CSI acquisition for non-codebook based PUSCH;

[0209] The second usage comprises at least one of:

[0210] Downlink CSI acquisition;

[0211] Uplink CSI acquisition;

[0212] CSI acquisition for codebook based physical shared channel (PUSCH);

[0213] CSI acquisition for non-codebook based PUSCH;

[0214] Beam management;

[0215] Positioning.

[0216] The first usage is different from the second usage, for example, if the first usage is uplink CSI acquisition, the second usage is at least one of downlink CSI acquisition, CSI acquisition for codebook based physical shared channel (PUSCH), CSI acquisition for non-codebook based PUSCH, beam management, and positioning. In this way, the first SRS resource can be used for at least two of downlink CSI acquisition, uplink CSI acquisition, CSI acquisition for codebook based physical shared channel (PUSCH), CSI acquisition for non-codebook based PUSCH, beam management, and positioning, and in this way, SRS transmission overhead can be reduced.

[0217] Optionally, the first usage is downlink CSI acquisition (e.g., usage of the corresponding SRS resource set is configured as “antennaSwitching”), and the second usage is uplink CSI acquisition.

[0218] Optionally, the first usage is beam management (e.g., usage of the corresponding SRS resource set is configured as “beamManagement”), and the second usage is uplink CSI acquisition.

[0219] Optionally, the first usage is uplink CSI acquisition, and the second usage is downlink CSI acquisition.

[0220] Optionally, the first usage is uplink CSI acquisition, and the second usage is beam management.

[0221] Optionally, the first usage is uplink CSI acquisition, and the second usage is positioning.

[0225] Optionally, the first usage is positioning, and the second usage is beam management.

[0226] Optionally, the first usage is positioning, and the second usage is downlink CSI acquisition.

[0227] As an optional implementation, the first usage type is “antennaSwitching”, and the second usage is “codebook”.

[0228] Optionally, the first usage type is “antennaSwitching”, and the second usage is “nonCodebook”.

[0229] Optionally, the first usage type is “beamManagement”, and the second usage is “codebook”.

[0230] Optionally, the first usage type is “beamManagement”, and the second usage is “nonCodebook”.

[0231] Optionally, the first usage type is “codebook”, and the second usage is “antennaSwitching”.

[0232] Optionally, the first usage type is “codebook”, and the second usage is “beamManagement”.

[0233] Optionally, the first usage type is “nonCodebook”, and the second usage is “antennaSwitching”.

[0234] Optionally, the first usage type is “nonCodebook”, and the second usage is “beamManagement”.

[0235] Optionally, the usage type corresponds to the usage, and the first usage type includes at least one of the following:

[0236] a codebook type;

[0237] a non-codebook type;

[0238] an uplink CSI type;

[0239] an antenna switching type;

[0240] a beam management type;

[0241] and / or

[0242] a second usage type comprises at least one of:

[0243] a codebook type;

[0244] a non-codebook type;

[0245] an uplink CSI type;

[0246] an antenna switching type;

[0247] a beam management type.

[0248] As some examples, when usage signaling of one SRS resource set is configured as “codebook”, the usage type of the SRS resource set is considered as the codebook type.

[0249] As some examples, when usage signaling of one SRS resource set is configured as “nonCodebook”, the usage type of the SRS resource set is considered as the non-codebook type.

[0250] As some examples, when usage signaling of one SRS resource set is configured as “beamManagement”, the usage type of the SRS resource set is considered as the beam management type.

[0251] As some examples, when usage signaling of one SRS resource set is configured as “antennaSwitching”, the usage type of the SRS resource set is considered as the downlink CSI acquisition type.

[0252] It should be noted that the codebook type corresponds to CSI acquisition of a physical shared channel PUSCH based on a codebook, the non-codebook type corresponds to CSI acquisition of a PUSCH without a codebook, the uplink CSI type corresponds to uplink CSI acquisition, the antenna switching type corresponds to downlink CSI acquisition, and the beam management type corresponds to beam management.

[0253] Optionally, according to the first information, the SRS corresponding to the first SRS resource is sent to the network device, comprising: determining the first SRS resource according to the first information; and in the case that the second usage is downlink CSI acquisition, determining the uplink filtering of the SRS corresponding to the first SRS resource according to downlink signal reception filtering.

[0254] The first information can indicate that the first SRS resource is used for multiple purposes. After receiving the first information, the first SRS resource corresponding to the first information can be determined. In the case that the second purpose is downlink CSI acquisition, the uplink filtering manner can be determined according to the downlink filtering manner of the specific signal, and the SRS corresponding to the first SRS resource is transmitted to the network device through the uplink filtering manner, so as to improve the transmission stability.

[0255] As an example, in the case that the second purpose is downlink CSI acquisition and the first purpose type is a codebook type, the uplink filtering manner of the SRS corresponding to the first SRS resource is determined according to the downlink filtering manner of the specific signal, that is, the SRS corresponding to the first SRS resource is transmitted by using the uplink filtering manner determined according to the downlink filtering manner of the specific signal. As an example, in the case that the second purpose is downlink CSI acquisition and the first purpose type is a codebook type, or the second purpose is downlink CSI acquisition and the first purpose type is a non-codebook type, the SRS of the SRS resource in the first SRS resource which is the same as the second SRS resource set configured with the second purpose type is transmitted by using the uplink filtering manner determined according to the downlink filtering manner of the specific signal.

[0256] Optionally, the specific signal can be a signal indicated by the network device. For example, the specific signal is a spatial quasi co-location (QCL) reference signal configured as the SRS resource of the second purpose type.

[0257] Optionally, the specific signal can also be a spatial relation information (SpatialRelationInfo) reference signal configured as the SRS resource of the second purpose type.

[0258] As an example, the downlink filtering manner of the specific signal is used as the uplink filtering of the SRS transmitted by the first SRS resource.

[0259] Optionally, the first SRS resource includes:

[0260] The SRS resource set configured as the first purpose type is the same as the SRS resource in the second SRS resource set configured as the second purpose type. The second purpose type corresponds to the second purpose.

[0261] That is, in the embodiment, the first SRS resource includes the same resource in the SRS resource set of two different purposes, so that the first SRS resource can be used for the first purpose and the second purpose, the SRS corresponding to the first SRS resource for the first purpose and the second purpose is transmitted, the first purpose and the second purpose are realized, and the SRS transmission overhead is reduced.

[0262] Optionally, the first SRS resource includes: the SRS resource set configured as the first purpose type and the time domain type as a specific type is the same as the SRS resource in the second SRS resource set.

[0263] That is, in the embodiment, the first SRS resource includes the same resource in the SRS resource set of the first usage type of the two usages, and the time domain type of the SRS resource set of the first usage type of the two usages is a specific type. Thus, the first SRS resource includes the SRS resource used for the two different usages and the time domain type is the specific type. The SRS corresponding to the first SRS resource used for the first usage and the second usage is transmitted, the first usage and the second usage are implemented, and the SRS transmission overhead is reduced.

[0264] Optionally, the first information is carried in first signaling or the first information is carried in SRS resource set configuration signaling sent by the network device to the terminal.

[0265] The first signaling includes at least one of the following:

[0266] Radio resource control (RRC) signaling;

[0267] Medium access control (MAC) control element (CE) signaling;

[0268] Downlink control information (DCI) signaling;

[0269] SRS triggering signaling.

[0270] That is, in the embodiment, the first signaling can be signaling used to indicate the first information, or the first information is carried in SRS resource set configuration signaling sent by the network device to the terminal, and is sent to the terminal through the configuration signaling.

[0271] That is, the indication is performed by using a special first signaling. It should be noted that the first signaling has different states, and different indications correspond to different states. At least one state of the first signaling is used to indicate that all or part of the resources of the SRS resource set of the first usage type are used for the second usage, that is, the state of the first signaling indicates the first information. As an example, another state of the signaling can be used to indicate that the SRS resource set of the first usage type is not used for the second usage. As an example, another state of the first signaling can be used to indicate that the SRS resource set of different usage types is not used for multiplexing.

[0272] For example, the first signaling includes two states, one of which indicates that the SRS resource set with usage type of downlink CSI acquisition (e.g., the SRS resource set configured with usage signaling of "antennaSwitching") can be used for uplink CSI acquisition, and the other indicates that only the SRS resource set with usage type of uplink CSI acquisition is used for uplink CSI acquisition (e.g., only the SRS resource set configured with usage signaling of "codebook" is used for CSI acquisition of codebook-based PUSCH, and only the SRS resource set configured with usage signaling of "nonCodebook" is used for CSI acquisition of non-codebook-based PUSCH). When the terminal receives the first signaling as state 0, the terminal determines that the SRS resource set with usage type configured as "antennaSwitching" is used for uplink CSI acquisition, and the terminal needs to consider factors such as CSI acquisition of PUSCH and antenna virtualization when transmitting the SRS resource set. When the UE receives the first signaling as state 1, the terminal does not need to consider factors such as CSI acquisition of PUSCH and antenna virtualization when transmitting the SRS resource set. As shown in Table 1 below.

[0273] Table 1

[0274]

[0275]

[0276] For another example, the first signaling includes multiple states, at least including: one state indicates that the SRS resource set with usage type x can be used for usage y, and another state indicates that the SRS resource set with usage type m can be used for usage n. Wherein x is different from y, m is different from n, x is the same as or different from m, y is the same as or different from n, when x = m, y is not equal to n; when y = n, x is not equal to m. As shown in Table 2.

[0277] Table 2

[0278]

[0279] Optionally, if the first signaling is SRS triggering signaling, it can be indicated by the SRS request field in the DCI.

[0280] Optionally, the trigger state of the SRS triggering signaling includes indication information of whether the SRS resource set of the first usage type is used for the second usage. That is, at least one state indicates that the SRS resource set of the first usage type can be used for the second usage.

[0281] Optionally, the indication information whether the SRS resource set triggered by the SRS triggering signaling is used for the second use is included in the trigger state of the SRS triggering signaling.

[0282] Optionally, the indication information of the second use (e.g., information indicating that the SRS resource set triggered by the SRS triggering signaling is used for the second use) is included in the trigger state of the SRS triggering signaling.

[0283] Optionally, the indication information whether the SRS resource set triggered by the SRS triggering signaling is used for the second use is included in the bit state of the SRS request field.

[0284] Optionally, the indication information whether the SRS resource set triggered by the SRS triggering signaling is used for the second use is included in the bit state of the SRS request field.

[0285] Optionally, the indication information of the second use (e.g., information indicating that the SRS resource set triggered by the SRS triggering signaling is used for the second use) is included in the bit state of the SRS request field.

[0286] Optionally, the first information is carried in the SRS resource set configuration signaling sent by the network device to the terminal;

[0287] If the SRS resource set configuration signaling does not configure the SRS resource set of the second use type, it is determined that the SRS resource set configured as the first use type is also used for the second use; or,

[0288] If the SRS resource set configuration signaling has configured the SRS resource set of the second use type, and there are same SRS resources in the SRS resource set configured as the first use type and the SRS resource set configured as the second use type, it is determined that the SRS resource set configured as the first use type is also used for the second use or the same SRS resource in the SRS resource set configured as the first use type is also used for the second use.

[0289] That is, the terminal can determine whether the SRS resource set configuration signaling configures an SRS resource set of the second usage type, and if not, determine that the SRS resource set configured as the first usage type is also used for the second usage. It can be understood that when the SRS resource set configured for the terminal does not include an SRS resource set configured as the second usage type, the SRS resource set configured as the first usage type is also used for the second usage. If the SRS resource set configuration signaling configures an SRS resource set of the second usage type, the terminal can determine whether there is the same SRS resource in the SRS resource set configured as the first usage type and the second SRS resource set configured as the second usage type, and if there is the same SRS resource in the SRS resource set configured as the first usage type and the second SRS resource set, determine that the SRS resource set configured as the first usage type is also used for the second usage or the same SRS resource in the SRS resource set configured as the first usage type and the second SRS resource set is also used for the second usage.

[0290] The terminal determines the usage of the SRS resource set of the first usage type and / or how to transmit the SRS of the SRS resource set of the first usage type according to whether the network device configures the SRS resource set of the second usage type for the terminal.

[0291] Taking the first usage type as "antennaSwitching" and the second usage type as "codebook" as an example. If the network device does not configure an SRS resource set of the usage type "codebook" for the terminal in a certain BWP, the terminal can know that the SRS resource set of the usage type "antennaSwitching" in the BWP is used for uplink CSI acquisition of codebook-based PUSCH. Therefore, the terminal needs to consider antenna virtualization when transmitting the SRS of the SRS resource set of the usage type "antennaSwitching". If the network device configures an SRS resource set of the usage type "codebook" for the terminal in a certain BWP (bandwidth Part, bandwidth part), the terminal can know that the terminal does not need to assume that the SRS resource set of the usage type "antennaSwitching" is used for uplink CSI acquisition of codebook-based PUSCH when transmitting the SRS of the SRS resource set of the usage type "antennaSwitching" in the BWP.

[0292] In addition, the network device configures, for the terminal, a SRS resource set including a SRS resource set configured with the first usage type and a SRS resource set configured with the second usage type, and at least one SRS resource is the same in the two types of resource sets. At this time, the SRS resource set configured with the first usage type or the same SRS resource is used for the second usage at the same time.

[0293] It can be understood that the SRS resource set configured for the terminal includes a SRS resource set configured with the first usage type and a SRS resource set configured with the second usage type, and at least one SRS resource is the same in the two types of resource sets. At this time, the SRS transmission of at least one same SRS resource in the transmission of the SRS resource set configured with the first usage type is used for the second usage at the same time.

[0294] Still taking the first usage type as “antennaSwitching” and the second usage type as “codebook” as an example. Suppose that the network device does not configure, for the terminal, a SRS resource set with a usage type of “codebook” and a SRS resource set with a usage of “antennaSwitching” at the same time in a certain BWP, and there is a same SRS resource in the two SRS resource sets. If the same SRS resource is marked as SRS resource 1, the terminal can know that the SRS resource set with the usage type configured as “antennaSwitching” will be used for uplink CSI acquisition of codebook-based PUSCH. Therefore, the terminal needs to consider antenna virtualization and the like when transmitting the SRS resource 1 in the SRS resource set with the usage type of “antennaSwitching”.

[0295] Optionally, according to the first information, the SRS corresponding to the first SRS resource is transmitted to the network device, including:

[0296] According to the first information, the first SRS resource is determined;

[0297] In the case where the first SRS resource or the SRS resource set where the first SRS resource is located is not configured with spatial correlation information, the SRS corresponding to the first SRS resource set is transmitted to the network device using the uplink filtering mode corresponding to the spatial correlation information indicated by the SRS resource in the SRS resource set configured with one of the multiple usage types; or

[0298] In a case where the first SRS resource or the SRS resource set where the first SRS resource is located is not configured with a transmission configuration indication (TCI) state, the terminal transmits the SRS corresponding to the first SRS resource using an uplink filter corresponding to a TCI state indicated by the SRS resource or the SRS resource set configured as one of the multiple usage types.

[0299] For example, in a case where the SRS of the first SRS resource set where the first SRS resource is located is not configured with SpatialRelationInfo (a parameter of RRC (Radio Resource Control) signaling), the terminal transmits the SRS of the first SRS resource set using an uplink filter corresponding to SpatialRelationInfo indicated by the SRS of the SRS resource set of one of the multiple usage types. For example, the SRS of the SRS resource set of the usage type of antenanSwitching is configured with SpatialRelationInfo. It should be noted that SpatialRelationInfo configured for any SRS of the first SRS resource set can be found in the same configuration in SpatialRelationInfo indicated by the SRS resource set of one of the multiple usage types indicated by the usage type of the first SRS resource set.

[0300] For another example, in a case where the SRS of the first SRS resource set is not configured with a TCI (Transmission Configuration Indicator) state, the terminal transmits the SRS of the first SRS resource set using an uplink filter corresponding to a TCI state indicated by the SRS resource set of one of the multiple usage types. For example, the SRS of the SRS resource set of the usage type of antenanSwitching is configured with a TCI state. It should be noted that the TCI state configured for any SRS of the first SRS resource set can be found in the same configuration in the TCI state indicated by the SRS resource set of one of the multiple usage types.

[0301] Optionally, according to the first information, the terminal transmits the SRS corresponding to the first SRS resource to the network device, including:

[0302] According to the first information, the terminal determines the first SRS resource.

[0303] The uplink filter mode used for transmitting the SRS corresponding to the first SRS resource is determined according to one or more of a plurality of downlink filter modes used for receiving a physical downlink shared channel (PDSCH).

[0304] That is, in the embodiment, the uplink filter mode is determined according to one or more of a plurality of downlink filter modes used for receiving a physical downlink shared channel (PDSCH), so that the stability of transmitting the SRS can be improved.

[0305] As an example, one or more of a plurality of downlink filter modes used for receiving a physical downlink shared channel (PDSCH) is used as the uplink filter mode used for transmitting the SRS corresponding to the first SRS resource. As an example, the uplink filter mode used by each SRS of the first SRS resource is different.

[0306] Optionally, the number of the first SRS resource is a plurality,

[0307] According to the first information, the SRS corresponding to the first SRS resource is transmitted to the network device, including:

[0308] According to the first information, the first SRS resource is determined;

[0309] The SRS corresponding to different SRS resources in the first SRS resource is transmitted using different transmission parameters; wherein the transmission parameter includes at least one of the following:

[0310] Antenna port;

[0311] Physical antenna;

[0312] Power amplifier.

[0313] In this way, the transmission interference of the SRS corresponding to different SRS resources can be reduced, and the transmission stability can be improved.

[0314] Optionally, after transmitting the SRS corresponding to the first SRS resource to the network device according to the first information, the method further includes: determining the downlink filter used for receiving the physical downlink control channel (PDSCH) sent by the network device according to the uplink filter used for transmitting the SRS corresponding to the first SRS resource. In this way, the stability of downlink reception can be improved.

[0315] As an example, the uplink filter mode used for transmitting the SRS corresponding to the first SRS resource can be used as the downlink filter mode used for receiving the physical downlink control channel (PDSCH) sent by the network device.

[0316] That is, the terminal can use the uplink filter used for SRS transmission corresponding to the first SRS resource as a downlink filter mode for receiving PDSCH, and receive PDSCH transmitted by the network device through the downlink filter mode.

[0317] For example, the first usage type is "codebook" (CSI acquisition of codebook-based PUSCH), and the second usage is downlink CSI acquisition (usage type of the SRS resource set is antennaSwitching). The network device schedules the terminal to receive PDSCH. When receiving PDSCH, the terminal performs downlink filtering using the uplink filter used when SRS transmission of the SRS resource set with the usage type of codebook.

[0318] For another example, the first usage type is "nonCodebook" (CSI acquisition of non-codebook PUSCH), and the second usage is downlink CSI acquisition (usage type of the SRS resource set is antennaSwitching). The network device schedules the terminal to receive PDSCH. When receiving PDSCH, the terminal performs downlink filtering using the uplink filter used when SRS transmission of the SRS resource set with the usage type of nonCodebook.

[0319] For another example, the first usage type is "codebook" (CSI acquisition of codebook-based PUSCH), and the second usage is downlink CSI acquisition (usage type of the SRS resource set is antennaSwitching), and there is the same SRS resource in the SRS resource set with the usage type of codebook as in the SRS resource set with the usage type of antennaSwitching. The network device schedules the terminal to receive PDSCH. When receiving PDSCH, the terminal performs downlink filtering using the uplink filter used when transmission of the same SRS resource in SRS transmission of the SRS resource set with the usage type of codebook.

[0320] For another example, the first usage type is "nonCodebook" (CSI acquisition of non-codebook PUSCH), the second usage is downlink CSI acquisition (the usage type of the SRS resource set is antennaSwitching), and there is an SRS resource in the SRS resource set configured with the nonCodebook usage type that is the same as an SRS resource in the SRS resource set configured with the antennaSwitching usage type. The network device schedules the terminal to receive a PDSCH. When the terminal receives the PDSCH, the terminal performs downlink filtering using an uplink filtering manner used when the terminal transmits the same SRS resource in the SRS transmission of the SRS resource set with the nonCodebook usage type.

[0321] Optionally, in the process of sending, to the network device, an SRS corresponding to an SRS resource set in which the first SRS resource is located, SRSs corresponding to any two SRS resources in the SRS resource set in which the first SRS resource is located are transmitted at different time instants, and no uplink signal is transmitted between any two SRS resources configured in the same time slot in the SRS resource set in which the first SRS resource is located.

[0322] That is, the first SRS resource set in which the first SRS resource is located includes multiple SRS resources, and at least two SRS resources are configured in the same time slot. When the terminal needs to perform SRS transmission of the first SRS resource set, the terminal does not perform transmission of any uplink signal between any two SRS resources in the first SRS resource set in the same time slot, so as to improve transmission stability.

[0323] Optionally, after sending, to the network device, an SRS corresponding to the first SRS resource according to the first information, the following operations are further included:

[0324] Receiving SRS resource indication information of a physical uplink shared channel (PUSCH) sent by the network device, the SRS resource indication information indicating an SRS resource corresponding to the PUSCH transmission;

[0325] Transmitting the PUSCH by using the same antenna port as an SRS port of the SRS resource indicated by the SRS resource indication information.

[0326] Optionally, the SRS resource indication information indicates at least one SRS resource in the first SRS resource.

[0327] Optionally, the SRS resource indication information is associated with the last SRS transmission of the first SRS resource before a physical downlink control channel (PDCCH) carrying the SRS resource indication information.

[0328] The filtering manner used by the terminal device when transmitting the PUSCH is the same as the filtering manner of the SRS resource indicated by the SRS resource indication information in the latest SRS transmission of the first SRS resource set before the PDCCH carrying the SRS resource indication information. As an example, the filtering includes spatial filtering, that is, the terminal uses the same beamforming when transmitting the PUSCH as the SRS transmission.

[0329] Optionally, the method further includes:

[0330] determining a third SRS resource set satisfying a first association relationship with the PUSCH transmission, the first association relationship including that the filtering manner during the PUSCH transmission is determined according to the filtering manner of the SRS transmission of the third SRS resource set;

[0331] The third SRS resource set is one of the SRS resource set configured as the first usage type and the second SRS resource set that is transmitted most recently before the PDCCH carrying the scheduling information of the PUSCH; or

[0332] The third SRS resource set is one of the SRS resource set configured as the first usage type and the second SRS resource set that is transmitted most recently before the PDCCH scheduling the PUSCH.

[0333] Optionally, the terminal uses different antenna ports to transmit any two SRS resources in the same SRS resource set when transmitting the SRS resource set in which the first SRS resource is located.

[0334] Optionally, the terminal further receives an SRS resource indication (SRS resource indicator, SRI) sent by the network device, and determines the SRS resource used to determine the antenna port of the physical uplink shared channel (PUSCH) in the SRS resource set through the SRI. Through this way, the SRI can be used for antenna selection of the PUSCH, so that antenna selection gain is obtained.

[0388] It should be noted that the embodiment is an implementation of the corresponding network device in the embodiment shown in Figure 2 The specific implementation can be referred to the related description of the embodiment shown in Figure 2 The embodiment will not be described again to avoid repetition, and the same beneficial effects can also be achieved.

[0389] Optionally, the first usage type is "codebook" (CSI acquisition of codebook-based PUSCH), the second usage is downlink CSI acquisition (the usage type of the corresponding SRS resource set is antennaSwitching), or the first usage type is "nonCodebook" (CSI acquisition of non-codebook-based PUSCH), and the second usage type is downlink CSI acquisition (the usage type of the corresponding SRS resource set is antennaSwitching), when the UE transmits the SRS resource set of the first usage type, if multiple SRS resources in the SRS resource set of the first usage type are configured, and multiple SRS resources are configured in the same time slot, when multiple SRS resources configured in the same time slot in the SRS resource set of the first usage type are transmitted, the UE does not perform any uplink transmission between the multiple SRS resources.

[0390] The above signal transmission process will be described in detail in specific embodiments, the network device is a base station, and the terminal is a UE.

[0391] Currently, in the NR system, one or more SRS resources can be configured in each SRS resource set, each SRS resource can contain 1, 2 or 4 SRS ports, and for one BWP.

[0392] A base station can configure a UE with at most one SRS resource set with usage of 'codebook'. For this SRS resource set, at most 2 SRS resources can be configured in Rel-15 standard; when there are 2 SRS resources, each SRS resource contains the same SRS ports. In Rel-16 standard, when a UE is configured with full power transmission Mode 2, the UE can be configured with at most 4 SRS resources, and when multiple SRS resources are configured, different SRS resources have the same or different number of SRS antenna ports; when a UE is not configured with full power transmission Mode 2, at most 2 SRS resources can be configured and when there are 2 SRS resources, each SRS resource contains the same SRS ports. When multiple SRS resources are configured, these SRS resources can be configured with at most 2 different spatial relation parameters.

[0393] A base station can configure a UE with at most one SRS resource set with usage of 'nonCodebook', in which at most 4 SRS resources can be configured; each SRS resource contains 1 antenna port. A base station can configure a UE with at most one SRS resource set with usage of 'beamManagement'.

[0394] In one SRS resource set, K >= 1 SRS resources can be configured, where the maximum value of K is determined according to UE capability. Only one SRS resource in each SRS resource set can be transmitted at a given time, and SRS resources in different SRS resource sets in the same BWP with the same time domain type can be transmitted at the same time. When the number of transmit antennas of a UE is less than the number of receive antennas, the UE can transmit SRS in an antenna switching manner, so that the base station obtains downlink CSI of all receive antennas through SRS. Limited by UE capability, a UE can be configured with one or more SRS resource sets with usage of 'antennaSwitching'.

[0395] A base station can configure a UE with SRS resource sets with antenna switching types of 1T=1R, 2T=2R, 4T=4R, 1T2R, 1T4R or 2T4R. For 1T=1R, 2T=2R or 4T=4R, at most two uplink sounding reference signal (SRS) resource sets can be configured, and there is only one SRS resource in one SRS resource set, and the number of antenna ports is 1, 2 or 4, respectively.

[0396] For 1T2R, at most two SRS resource sets can be configured, each of which contains two SRS resources, each of which has only one port. The terminal transmits one SRS resource from one antenna (physical antenna) and the other SRS resource from another antenna (physical antenna).

[0397] For 2T4R, at most two SRS resource sets can be configured, each of which contains two SRS resources, each of which has two ports. The terminal transmits one SRS resource from two antennas (physical antennas) and the other SRS resource from another two antennas (physical antennas).

[0398] For 1T4R, at most one SRS resource set of periodic or semi-persistent time domain type can be configured, which contains four single-SRS-port SRS resources; two SRS resource sets of aperiodic time domain type can be configured, and the two SRS resource sets contain a total of four SRS resources (two SRS resource sets each contain two SRS resources; or one SRS resource set contains one SRS resource, and the other SRS resource set contains three SRS resources), which are transmitted in two time slots, and the four resources are transmitted through different physical antennas. The base station configures the same set of power control parameters for the two SRS resource sets, and triggers the two resources by the same control signaling (DCI signaling).

[0399] When the UE transmits SRS corresponding to the SRS resource set with usage of 'antennaSwitching', if multiple SRS resources in the same SRS resource set are transmitted in the same slot, a guard period should be left between these SRS resources, and the UE does not transmit any other signals in the guard period. The guard interval under different subcarrier spacings is shown in the following table. The unit is symbol.

[0400] Table 3

[0401] μ Δf = 2 μ · 15 [kHz] ] > Symbol interval 0 15 1 1 30 1 2 60 1 3 120 2

[0402] All SRS resources in the SRS resource set with usage of 'antennaSwitching' contain the same number of SRS ports.

[0403] For 1T2R, 1T4R, or 2T4R, the UE does not want multiple SRS resource sets with usage 'antennaSwitching' to be triggered in the same slot. For 1T=1R, 2T=2R, or 4T=4R, the UE does not want multiple SRS resource sets with usage 'antennaSwitching' to be triggered in the same symbol.

[0404] Currently, UEs do not simultaneously consider the needs of uplink CSI acquisition and downlink CSI acquisition when transmitting SRS resources. Therefore, base stations must configure separate SRS resource sets for uplink and downlink CSI acquisition and trigger and transmit them separately. This incurs significant SRS transmission and scheduling overhead, thus reducing system performance. Based on this, this invention provides a signal transmission method that reduces transmission overhead.

[0405] For example, such as Figure 4 As shown, the base station sends configuration information for SRS resource sets (including a first SRS resource set (RSRset1) and a second SRS resource set (RSRset2)) to the UE. Multiple purpose-type signaling simultaneously indicates the SRS resource sets acquired for both uplink CSI and downlink CSI (e.g., purpose type "codebook / antennaSwitching"). Both the first and second SRS resource sets are aperiodic. The UE performs SRS transmissions using these SRS resource sets, and the SRS transmissions for any two SRS resources use different physical antennas. The base station sends a PDSCH to the UE. When receiving the PDSCH, the UE uses the uplink filtering employed by the SRS transmissions of this SRS resource set for downlink filtering.

[0406] For example, the base station sends the configuration information of the SRS resource set to the UE, the usage type signaling of one SRS resource set is configured as "codebook / antennaSwitching", that is, the SRS resource set can be used for CSI acquisition of codebook-based PUSCH and downlink CSI acquisition at the same time, the SRS resource set is not configured with SpatialRelationInfo or TCI; the usage type signaling of another SRS resource set in the SRS resource set is configured as "codebook", and the SRS resource set is configured with SpatialRelationInfo or TCI. When the UE sends the SRS resource set with the usage type configured as "codebook / antennaSwitching", the transmission spatial filtering parameters of the SRS resource set with the usage type signaling configured as "codebook / antennaSwitching" are determined by using the SpatialRelationInfo or TCI configured in the SRS resource set with the usage type configured as "codebook".

[0407] Optionally, the terminal transmits any two SRS resources in the same SRS resource set using different antenna ports.

[0408] The network device sends SRS resource indication SRI information for indicating the SRS resource used for determining the antenna port of the physical uplink shared channel (PUSCH) from the SRS resource set. By this way, the SRI can be used for antenna selection of the PUSCH, so as to obtain the antenna selection gain.

[0409] The present application configures the SRS resource set which can be used for uplink CSI acquisition and downlink CSI acquisition at the same time. The needs of uplink CSI acquisition and downlink CSI acquisition can be considered at the same time when the UE transmits the SRS resource, so that the base station does not have to configure the SRS resource set for uplink CSI acquisition and downlink CSI acquisition respectively and trigger and transmit respectively. Therefore, the purpose of reducing the SRS transmission overhead and DCI scheduling overhead and improving the system performance is achieved.
