[0002] In the New Radio (NR) system, for 1T4R type antenna switching, if the configured sounding reference signal (SRS) resource is non-periodic, two SRS resource sets need to be configured. These two SRS resource sets have a total of 4 single-port (1-port) SRS resources. These two SRS resource sets need to be in two different time slots. In the sounding process corresponding to a 1T4R type antenna switching, the transmission of SRS needs to occupy 2 slots. That is, in order to complete the sounding process corresponding to a 1T4R type antenna switching, the transmission of SRS needs to occupy 2 slots, which will cause a longer sounding process time, and the detection performance will be reduced due to channel changes. Especially in the case of no continuous uplink time slots, the time of a sounding process is longer, and the impact of channel changes on detection performance is more obvious.

[0048] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be referred to as a communication device. Figure 1Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions.

[0049] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0050] The terms used in the implementation mode of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The terms "first", "second", "third" and "fourth" in the specification and claims of this application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0051] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0052] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0053] In the embodiments of the present application, "pre-definition" can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device), and the present application does not limit the specific implementation method. For example, pre-definition can refer to what is defined in the protocol.

[0054] In the embodiments of the present application, the “protocol” may refer to a standard protocol in the communication field, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and the present application does not limit this.

[0055] In order to facilitate a better understanding of the embodiments of the present application, the Multiple-Input Multiple-Output (MIMO) transmission related to the present application is described.

[0056] MIMO has been widely used in wireless communication systems, such as 3G, 4G (LTE), 5G (NR), and WiFi.

[0057] Using MIMO technology, you can get multiple forms of gain:

[0058] Spatial diversity gain, beamforming gain (precoding gain), spatial multiplexing gain.

[0059] In order to obtain beamforming gain (also called precoding gain) or spatial multiplexing gain, the transmitter needs to determine a beamforming matrix (or precoding matrix) for signal transmission. For the sake of simplicity, the following "precoding" and "beamforming" will be used interchangeably without distinction. That is, when any of the terms is used, the description can be applied to both "precoding" and "beamforming".

[0060] The determination of the precoding matrix often needs to be based on the corresponding transmission channel information. Optionally, on this basis, the determination of the precoding matrix can also be based on the channel information, interference information, etc. corresponding to the multi-user MIMO paired users. Therefore, for the determination of the precoding matrix of terminal A, a basic requirement is to obtain some form of channel information of the transmission channel corresponding to terminal A.

[0061] In an actual system, in order to obtain the channel information of the transmission channel corresponding to terminal A, there are two major methods:

[0062] 1. Feedback method: Base station B sends reference information X (e.g., Channel State Information Reference Signal (CSI-RS) signal), and terminal A measures and obtains information of the corresponding downlink channel according to reference signal X, and then determines the corresponding channel feedback information, which may include the following forms (which may be part or all). Base station B determines the corresponding precoding matrix according to the information fed back by terminal A and sends a physical downlink shared channel (PDSCH) or physical downlink control channel (PDCCH) to terminal A, or other downlink channels or downlink reference signals, such as rank indication (RI) (Description: rank information, corresponding to the number of transmission streams recommended by the terminal), channel quality indication (CQI) (Description: Modulation and Coding Scheme (MCS) related information), and precoding matrix indication (PMI) (Description: codebook information).

[0063] 2. Method based on channel reciprocity: Terminal A sends SRS information according to the configuration information of base station B. Base station B measures the corresponding uplink channel according to the received SRS information. According to the reciprocity of the uplink and downlink channels, base station B can determine the precoding matrix corresponding to terminal A for sending PDSCH or PDCCH, or other downlink channels or downlink reference signals.

[0064] The above feedback method can be used in a time division duplex (TDD) system and a frequency division duplex (FDD) system; while the method based on channel reciprocity is generally mainly used in a TDD system, and can also be used in an FDD system with partial reciprocity (without restriction by the protocol).

[0065] In order to facilitate a better understanding of the embodiments of the present application, the antenna switching related to the present application is explained.

[0066] From the above introduction to MIMO transmission, we can see that the method based on channel reciprocity requires terminal A to send an SRS signal. In NR, the configuration of the SRS resource set corresponding to this type of SRS signal is as follows:

[0067] The usage in the SRS-ResourceSet is set to "antenna switching", and one SRS-ResourceSet contains one or more SRS resources.

[0068] This type of SRS signal sounding process is also called a UE sounding procedure for DLCSI acquisition, and may also be called SRS Tx port switching.

[0069] For a typical smartphone, the number of receiving antennas is often greater than the number of transmitting antennas, e.g. Figure 2 As shown in the figure, terminal A has two receiving antennas, but only one transmitting antenna (at a single moment). Therefore, if terminal A sends an SRS (when there is a single antenna, the corresponding SRS resource is 1 SRS port), base station B can only obtain 8*1 channels, that is, the channel information corresponding to half of the channels is unknown, which will affect the acquisition of better precoding performance.

[0070] To solve the above problem, the network can configure two 1-port SRS resources. The two SRS resources are transmitted from two antennas at different times. For example, the SRS signal corresponding to SRS resource 0 is transmitted from antenna 0 at time T0, and the SRS signal corresponding to SRS resource 1 is transmitted from antenna 1 at time T1. In this way, through two SRS transmissions, base station B can obtain 8*2 channel information. The above two SRS resources will be configured in the same SRS resource set, and the corresponding usage will also be set to "antennaSwitching".

[0071] The number of transmitting antennas and receiving antennas of terminal A, as well as whether "antenna switching" is supported (equivalently, whether SRS Tx port switching is supported) can be implemented differently. It can be reported through UE capability. At present, the UE capability reports corresponding to the NR of release 15 (Rel-15) are as follows: t1r2, t1r4, t2r4, t1r4-t2r4, t1r1, t2r2, t4r4, not supported (notSupported), among which t1r2 corresponds to 1T2R, t2r4 corresponds to 2T4R, t1r4 corresponds to 1T4R, t1r4-t2r4 corresponds to 1T4R or 2T4R, t1r1 corresponds to 1T=1R, t2r2 corresponds to 2T=2R, and t4r4 corresponds to 4T=4R.

[0072] For 1T2R: You can configure 0, 1, or 2 SRS resource sets. The resource types (resourceType) corresponding to these two resource sets are configured with different values, which can be aperiodic, semi-persistent, or periodic. When you configure two SRS resource sets later, they are similar and will not be explained again. Each resource set contains two single-port (1-port) SRS resources. These two SRS resources are transmitted from different symbols, and the two SRS resources in the same resource set correspond to different terminal antenna ports (UE antenna ports).

[0073] For 2T4R: 0, 1, or 2 SRS resource sets can be configured. Each resource set contains 2 SRS resources, each SRS resource is 2 SRS ports, the two SRS resources are transmitted from different symbols, and the UE antenna port pair corresponding to the SRS port pair of the second SRS resource in the same resource set is different from the UE antenna port pair corresponding to the SRS port pair of the first SRS resource.

[0074] For 1T4R: 0 or 1 SRS resource set can be configured (periodic or semi-continuous). Each resource set contains 4 single-port (1-port) SRS resources, each SRS resource is transmitted from a different symbol, and different SRS resources correspond to different UE antenna ports.

[0075] For 1T4R: 0 or 2 SRS resource sets can be configured (both configured as non-periodic). A total of 4 single-port (1-port) SRS resources in the 2 resource sets are transmitted from different symbols of two different slots. The 4 SRS resources correspond to different UE antenna ports. The 4 SRS resources can be 2 SRS resources per resource set, or 1 resource set can contain 3 SRS resources and the other resource set can contain 1 SRS resource. The power parameters configured by the Radio Resource Control (RRC) corresponding to the two resource sets are the same, and the high-level parameter aperiodic SRS resource trigger condition (aperiodicSRS-ResourceTrigger) is the same, but the parameter slot offset (slotOffset) is different.

[0076] For 1T=1R, or 2T=2R, or 4T=4R: 0, 1, or 2 SRS resource sets can be configured. Each resource set contains 1 SRS resource. The SRS ports corresponding to the SRS resource are 1, 2, or 4, respectively.

[0077] If the terminal device reports that it supports "t1r4-t2r4", all SRS resources in the SRS resource set must be configured with the same SRS port (1 or 2 SRS port).

[0078] It should be noted that, to describe different antenna switching configurations, "xTyR" is generally used (the xTyR description method is generally used in the physical layer protocol. If x and y are equal, it is often expressed as xT=yR), or "txry" (UE capability signaling is generally described using txry in the high-level protocol), where x and y represent positive integers greater than 0. These two description methods are corresponding or equivalent. In order to simplify the identification, the embodiments of the present application uniformly use xTyR to represent the corresponding antenna switching. When x=y, it is expressed as xT=yR.

[0079] In order to facilitate a better understanding of the embodiments of the present application, the antenna switching interval related to the present application is explained.

[0080] In antenna switching, a switching time is required, that is, the interval between SRS resources transmitted in the same slot in the same resource set is Y symbols, where the value of Y is shown in Table 1 below.

[0081] Table 1

[0082] μ <![CDATA[Δf=2 μ ·15[kHz]]]> Y[symbol] 0 15 1 1 30 1 2 60 1 3 120 2

[0083] Different μ corresponds to different subcarrier spacing (SCS), and Δf is the subcarrier spacing (in kHz).

[0084] For 1T4R type antenna switching, if the configured SRS resources are non-periodic, two SRS resource sets need to be configured, and the two resource sets need to be transmitted in different time slots. That is, in order to complete the sounding process corresponding to a 1T4R type antenna switching, the transmission of SRS needs to occupy 2 slots, which will cause a longer sounding process and performance degradation due to channel changes. Especially in the case of no continuous uplink time slots, the sounding process takes longer and the impact of channel changes on performance is more obvious.

[0085] Based on the above problems, the present application proposes a wireless communication solution, which can complete the non-periodic detection process corresponding to the 1T4R type antenna switching within one time slot, thereby reducing the detection delay.

[0086] The technical solution of the present application is described in detail below through specific embodiments.

[0087] Figure 3 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, such as Figure 3 As shown, the method 200 may include at least part of the following contents:

[0088] S210, the first device sends configuration information to the terminal device, where the configuration information is used to indicate G SRS resource sets, where the G SRS resource sets include a first SRS resource set, where G is an integer and G≥1; wherein the resource type configuration corresponding to the first SRS resource set is non-periodic, the first SRS resource set corresponds to a 1T4R type antenna switching configuration, and the four SRS resources in the first SRS resource set are on different symbols of the same time slot, and the four SRS resources are single-port SRS resources;

[0089] S220: The terminal device receives the configuration information.

[0090] In an embodiment of the present application, since the four SRS resources in the first SRS resource set are on different symbols of the same time slot, that is, the terminal device can complete the non-periodic detection process corresponding to the 1T4R type antenna switching within one time slot based on the four SRS resources in the first SRS resource set, thereby reducing the detection delay.

[0091] Optionally, the first device may be a network device. The above S210 may specifically be: the network device sends an RRC signaling carrying the configuration information to the terminal device, thereby supporting communication between the terminal and the network.

[0092] Optionally, the first device may also be another terminal device, for example, communicating with the terminal device via D2D communication, or communicating with the terminal device via V2X, or communicating with the terminal device via a sidelink. The above S210 may specifically be: the other terminal device sends a PC5-RRC signaling carrying the configuration information to the terminal device. Thus, communication between terminals can be supported.

[0093] Optionally, the configuration information may be a non-periodic detection process corresponding to one 1T4R type antenna switching, that is, the G SRS resource sets include only one first SRS resource set. The configuration information may also be a non-periodic detection process corresponding to multiple 1T4R type antenna switching, that is, the G SRS resource sets include multiple first SRS resource sets.

[0094] In the embodiment of the present application, the usage domain or field in the RRC information element (IE) corresponding to each SRS resource set in the G SRS resource sets is set to antenna switching.

[0095] In addition, the resource type (resourceType) in the resource set (SRS-ResourceSet) corresponding to each SRS resource set in the G SRS resource sets can be configured as one of the following: aperiodic, semi-persistent, or periodic (different resource sets can be configured with different resource type values).

[0096] For example, the resource type value is aperiodic. For another example, the resource type value is semi-persistent. For another example, the resource type value is periodic.

[0097] Optionally, SRS ports of the four SRS resources in the first SRS resource set correspond to different terminal antenna ports (UE antenna ports).

[0098] Optionally, in some embodiments, the interval between adjacent SRS resources in the four SRS resources in the first SRS resource set is Y symbols, where Y is an integer and Y≥1. Specifically, the symbols spaced apart between the four SRS resources are not used to transmit signals. That is, the terminal device does not transmit signals on the spaced symbols between the four SRS resources. Accordingly, the network device does not expect the terminal device to transmit signals on the spaced symbols between the four SRS resources.

[0099] Optionally, in some other embodiments, the interval between adjacent SRS resources in the four SRS resources in the first SRS resource set is ≥ Y symbols, Y is an integer, and Y ≥ 1. That is, the interval between adjacent SRS resources may also be greater than Y symbols, thereby increasing the flexibility of configuring SRS resources. Specifically, the symbols spaced between the four SRS resources are not used to transmit signals. That is, the terminal device does not transmit signals on the spaced symbols between the four SRS resources. Accordingly, the network device does not expect the terminal device to transmit signals on the spaced symbols between the four SRS resources.

[0100] Optionally, in some embodiments, the four SRS resources in the first SRS resource set do not occupy the first Y symbols of a time slot, where Y is an integer and Y≥1. This ensures a certain switching time with the SRS transmitted in the previous time slot, thereby reducing the implementation complexity of the terminal.

[0101] Optionally, Y is for a part of the subcarrier spacings in the P subcarrier spacings, and each subcarrier spacing in the part of the P subcarrier spacings corresponds to a Y value, P is an integer, and P ≥ 4. Optionally, the remaining subcarrier spacings in the P subcarrier spacings can be determined by reporting terminal capability information. It can be determined according to the different capabilities of the terminal. On the one hand, for terminals with strong capabilities, the protection interval can be reduced to reduce the system overhead; on the other hand, the implementation complexity and / or cost of low-capability terminals can be reduced, which is convenient for the promotion of low-capability terminals.

[0102] Optionally, the part of the subcarrier spacings in the P subcarrier spacings includes the following four types:

[0103] 15kHz, 30kHz, 60kHz, 120kHz.

[0104] Among them, a subcarrier spacing of 15 kHz corresponds to Y = 1, a subcarrier spacing of 30 kHz corresponds to Y = 1, a subcarrier spacing of 60 kHz corresponds to Y = 1, and a subcarrier spacing of 120 kHz corresponds to Y = 2. The subcarrier spacing and Y may also have other corresponding relationships, which are not limited in this application.

[0105] In addition, the part of the P subcarrier spacings may also include at least one of the following subcarrier spacings:

[0106] 15kHz, 30kHz, 60kHz, 120kHz.

[0107] Optionally, the P subcarrier spacings include part or all of the following:

[0108] 15kHz, 30kHz, 60kHz, 120kHz, 240kHz, 480kHz, 960kHz, 1920kHz.

[0109] Optionally, Y is pre-configured or agreed upon by protocol, wherein a subcarrier spacing of 15 kHz corresponds to Y = 1, a subcarrier spacing of 30 kHz corresponds to Y = 1, a subcarrier spacing of 60 kHz corresponds to Y = 1, and a subcarrier spacing of 120 kHz corresponds to Y = 2. There may also be other corresponding relationships between the subcarrier spacing and Y, which are not limited in this application.

[0110] Optionally, Y is determined according to the subcarrier spacing. For example, for a subcarrier spacing of 15kHz, Y=1; for a subcarrier spacing of 30kHz, Y=1; for a subcarrier spacing of 60kHz, Y=1; for a subcarrier spacing of 120kHz, Y=2. The subcarrier spacing and Y may also be other corresponding relationships, which are not limited in this application.

[0111] Optionally, in some embodiments, the G SRS resource sets include at least one second SRS resource set, wherein the second SRS resource set corresponds to an xTyR type antenna switching configuration, and xTyR is different from 1T4R. Therefore, the same terminal device can be configured with SRS of different antenna switching types, so that the network device or other terminal devices can flexibly support different types of antenna switching, obtain better resource utilization, and reduce the power consumption of the terminal.

[0112] Optionally, the xTyR is one of the following:

[0113] 1T1R, 1T2R, 1T6R, 1T8R, 2T4R, 2T8R, 4T6R, 4T8R.

[0114] In addition, in some implementations, xTyR and 1T4R may also be the same, that is, the second SRS resource set may also correspond to a 1T4R type antenna switching configuration.

[0115] Optionally, in some implementations, the resource type configuration value corresponding to the second SRS resource set is different from the resource type configuration corresponding to the first SRS resource set. Therefore, the network device can use a periodic resource set (such as 1T1R) for transmission to obtain part of the downlink channel information, which can ensure basic transmission while reducing SRS resource overhead. When the downlink data transmission increases, 1T4R can be dynamically triggered to obtain more downlink new information, thereby improving downlink transmission performance.

[0116] For example, the resource type configuration value corresponding to the second SRS resource set is semi-persistent, and the resource type configuration value corresponding to the first SRS resource set is non-periodic.

[0117] Optionally, in some other implementations, the resource type configuration value corresponding to the second SRS resource set is the same as the resource type configuration value corresponding to the first SRS resource set. For example, the resource type configuration value corresponding to the first SRS resource set is non-periodic, and the resource type configuration value corresponding to the second SRS resource set is also non-periodic, that is, both are non-periodic SRS resource sets, which can provide maximum flexibility for network devices or other terminal devices to trigger SRS transmission.

[0118] Optionally, in some implementations, the SRS transmission corresponding to the second SRS resource set and the SRS transmission corresponding to the first SRS resource set cannot be in the same time unit.

[0119] Optionally, the time unit includes but is not limited to at least one of the following:

[0120] Time slot, symbol.

[0121] For example, the SRS transmission corresponding to the second SRS resource set and the SRS transmission corresponding to the first SRS resource set cannot be in the same time slot, thereby saving SRS resources and reducing the complexity of configuring and triggering the SRS scheduling process.

[0122] For another example, the SRS transmission corresponding to the second SRS resource set and the SRS transmission corresponding to the first SRS resource set cannot be on the same symbol, thereby reducing the terminal processing complexity and also reducing the receiving complexity of the receiving side.

[0123] Optionally, in some other implementations, when the SRS transmission corresponding to the second SRS resource set and the SRS transmission corresponding to the first SRS resource set are in the same time unit, the transmission priority of the SRS to be transmitted is determined based on the resource type configuration corresponding to the first SRS resource set and the resource type configuration corresponding to the second SRS resource set, and the terminal device does not transmit the SRS transmission with a lower priority between the SRS transmission corresponding to the first SRS resource set and the SRS transmission corresponding to the second SRS resource set.

[0124] That is, when the SRS transmission corresponding to the second SRS resource set and the SRS transmission corresponding to the first SRS resource set are in the same time unit, the terminal device can determine the priority of transmitting the SRS based on the resource type configuration corresponding to the first SRS resource set and the resource type configuration corresponding to the second SRS resource set.

[0125] Optionally, the SRS transmission priority corresponding to the resource type configuration includes:

[0126] Aperiodic takes precedence over periodic; and / or,

[0127] Aperiodic takes precedence over semi-persistent; and / or,

[0128] Semi-persistent takes precedence over periodic.

[0129] Assume that the SRS transmission corresponding to the second SRS resource set and the SRS transmission corresponding to the first SRS resource set are in the same time unit. For example, if the resource type corresponding to the first SRS resource set is configured as non-periodic, and the resource type corresponding to the second SRS resource set is configured as periodic, the terminal device transmits the SRS transmission corresponding to the first SRS resource set, and does not transmit the SRS transmission corresponding to the second SRS resource set. For another example, if the resource type corresponding to the first SRS resource set is configured as non-periodic, and the resource type corresponding to the second SRS resource set is configured as semi-persistent, the terminal device transmits the SRS transmission corresponding to the first SRS resource set, and does not transmit the SRS transmission corresponding to the second SRS resource set.

[0130] Optionally, in some implementations, the interval between the SRS resource transmission corresponding to the first SRS resource set and the SRS resource transmission corresponding to the second SRS resource set is ≥ M symbols, where M is an integer and M ≥ 1. Thus, a certain switching time can be ensured between the first SRS resource set and the second SRS resource set, thereby reducing the implementation complexity of the terminal.

[0131] Optionally, M is for a part of the subcarrier spacings in the Q subcarrier spacings, and each subcarrier spacing in the part of the Q subcarrier spacings corresponds to an M value, Q is an integer, and Q ≥ 4. Optionally, the remaining subcarrier spacings in the Q subcarrier spacings can be determined by reporting terminal capability information. It can be determined according to the different capabilities of the terminal. On the one hand, for terminals with strong capabilities, the protection interval can be reduced to reduce the system overhead; on the other hand, the implementation complexity and / or cost of low-capability terminals can be reduced, which is convenient for the promotion of low-capability terminals.

[0132] Optionally, the part of the subcarrier spacings in the Q subcarrier spacings includes the following four types:

[0133] 15kHz, 30kHz, 60kHz, 120kHz.

[0134] Among them, a subcarrier spacing of 15 kHz corresponds to M = 1, a subcarrier spacing of 30 kHz corresponds to M = 1, a subcarrier spacing of 60 kHz corresponds to M = 1, and a subcarrier spacing of 120 kHz corresponds to M = 2.

[0135] In addition, the part of the Q subcarrier spacings may also include at least one of the following subcarrier spacings:

[0136] 15kHz, 30kHz, 60kHz, 120kHz.

[0137] Optionally, the Q subcarrier spacings include part or all of the following:

[0138] 15kHz, 30kHz, 60kHz, 120kHz, 240kHz, 480kHz, 960kHz, 1920kHz.

[0139] Optionally, M is pre-configured or agreed upon by the protocol, wherein a subcarrier spacing of 15 kHz corresponds to M=1, a subcarrier spacing of 30 kHz corresponds to M=1, a subcarrier spacing of 60 kHz corresponds to M=1, and a subcarrier spacing of 120 kHz corresponds to M=2. There may also be other corresponding relationships between the subcarrier spacing and M, which are not limited in the embodiments of the present application.

[0140] Optionally, M is determined according to the subcarrier spacing. For example, for a subcarrier spacing of 15kHz, M=1; for a subcarrier spacing of 30kHz, M=1; for a subcarrier spacing of 60kHz, M=1; for a subcarrier spacing of 120kHz, M=2. There may also be other corresponding relationships between the subcarrier spacing and M, which are not limited in the embodiments of the present application.

Further, the first device may determine the configuration information according to the first terminal capability information.

Further, the first device may determine the configuration information according to the second terminal capability information.

For example, the second terminal capability information can indicate that the terminal device indicates that SRS is transmitted on the last K symbols of a time slot (K>6). Further, the first device can determine the configuration information based on the second terminal capability information. For example, K=8.

[0148] That is, before receiving the configuration information, the terminal device sends the second terminal capability information.

[0149] Optionally, the second terminal capability information is for non-shared spectrum channel access, so that it can be extended to scenarios other than shared spectrum channel access.

[0150] Optionally, the second terminal capability information is for licensed spectrum channel access. Thus, it can be extended to a scenario for licensed spectrum channel access.

[0151] The existing terminal only supports sending SRS on the last 6 symbols of a time slot. After adding the second terminal capability information, the SRS resources corresponding to the 1T4R type antenna switching configuration can be configured in the same time slot.

[0152] Optionally, in some embodiments, the terminal device sends third terminal capability information to the first device, and the third terminal capability information is used to indicate that the terminal device supports the transmission of a non-periodic SRS configuration corresponding to the 1T4R type in a time slot. Further, the first device can determine the configuration information according to the third terminal capability information.

[0153] That is, before receiving the configuration information, the terminal device sends the third terminal capability information.

[0154] Optionally, in an embodiment of the present application, SRS ports of different SRS resources in the same SRS resource set correspond to different terminal antenna ports.

[0155] Optionally, in this embodiment of the present application, part or all of the SRS resources in each SRS resource set in the G SRS resource sets correspond to one of the following subcarrier spacings:

[0156] 15kHz, 30kHz, 60kHz, 120kHz, 240kHz, 480kHz, 960kHz, 1920kHz.

[0157] Optionally, in an embodiment of the present application, the terminal device may send an SRS signal according to the configuration information.

[0158] Accordingly, the first device can receive the SRS signal sent by the terminal device according to the configuration information; determine the precoding corresponding to the terminal device according to the measurement result of the received SRS signal; and send a channel and / or signal to the terminal device according to the precoding. In the case where the first device is a network device, the channel can be PDSCH or PDCCH, or other downlink channels. In the case where the first device is other terminal devices, the channel can be a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) or a physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH), or other sidelink channels.

[0159] The following describes possible positions of four single-port SRS resources in the first SRS resource set in a time slot in an embodiment of the present application through Example 1 and Example 2 respectively.

[0160] In Example 1, when Y=1 (15kHz, 30kHz, 60kHz) and the interval between adjacent SRS resources is Y, the possible positions of the four single-port SRS resources in the first SRS resource set in a time slot can be as follows: Figure 4 It should be noted that the four SRS resources in the first SRS resource set may occupy the first symbol of a time slot, as shown in case 8, that is, the four SRS resources in the first SRS resource set may also occupy the first Y symbols of a time slot.

[0162] Therefore, in an embodiment of the present application, since the four SRS resources in the first SRS resource set are on different symbols of the same time slot, that is, the terminal device can complete the non-periodic detection process corresponding to the 1T4R type antenna switching within one time slot based on the four SRS resources in the first SRS resource set, thereby reducing the detection delay.
