Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an information transmission method, apparatus, terminal, and network device. Background Art

[0002] For Coherent Joint Transmission (CJT), under the non-ideal reciprocity assumption, the uplink and downlink channels between a User Equipment (UE) and multiple cooperation points are no longer transpose relations with each other. Correspondingly, the precoding codeword obtained by the network side through uplink channel estimation no longer matches the actual downlink channel. The UE can report the phase difference between the cooperation points to the network side, and the network side calculates a calibration coefficient based on the phase difference to pre-compensate the uplink channel, and then determines a downlink precoding matrix for downlink transmission. The key for the network side to correctly estimate the calibration coefficient lies in obtaining accurate uplink and downlink channel information. However, the current protocol mechanism cannot ensure that the transmission of a reference signal for downlink channel measurement (such as a Channel State Information Reference Signal (CSI-RS)) or the reporting of Channel State Information (CSI) (corresponding to downlink channel information estimation) is close enough in time to the transmission of a reference signal for estimating uplink channel measurement (such as a Sounding Reference Signal (SRS)), or cannot ensure that the two correspond to the same transmission parameters, resulting in inaccurate calibration coefficients calculated by the network side.

Obviously, the described embodiments are some, rather than all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0206] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein, for example, can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0207] The term "and / or" in the embodiments of the present application describes the association relationship of associated objects and indicates that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after. The term "plurality" in the embodiments of the present application refers to two or more, and other quantifiers are similar thereto.

[0208] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0209] The relevant concepts mentioned in this application are briefly described as follows.

[0210] 1. CJT Transmission

[0211] Rel-18 standardized the CJT technology, supporting coherent transmission of up to 4 Transmission and Reception Points (TRPs). Assuming the channels between the 4 TRPs and the UE are H i , the signal y received by the UE can be expressed as:[

[0212] y = [H1 H2 H3 H4]Wx + n

[0213] where W is the precoding codeword for joint transmission by the 4 TRPs, x is the signal sent by each TRP, and n is the receiver noise. From the above formula, it can be seen that in CJT transmission, the precoding codewords of all TRPs can be written in the form of a joint matrix, that is, the precoding codeword is jointly determined according to the channel conditions of all TRPs.

[0214] 2. CSI-RS Resource Configuration

[0215] The current system supports CSI-RS for CSI measurement and CSI-RS for beam measurement. In CSI measurement, the network side can configure a CSI-RS resource setting for the UE, which includes one or more CSI-RS resource sets, and each CSI-RS resource set includes one or more CSI-RS resources.

[0216] 3. CSI Reporting

[0217] The current system supports beam measurement reporting and CSI measurement reporting. In CSI reporting, the network side can configure a CSI reporting setting for the UE. Each CSI reporting setting is associated with one or more CSI resource sets, and each CSI resource set includes one or more CSI-RS resources. The UE reports according to the reporting quantity configured by the network side.

[0218] 4. SRS Trigger

[0219] The current system supports CSI measurement SRS, beam management SRS, etc. In uplink CSI measurement, the network side can configure one or more SRS resource sets for the UE, and each SRS resource set includes one or more SRS resources. The UE triggers SRS transmission according to the signaling configured by the network side.

[0220] There is no association relationship between the CSI-RS resource configuration, CSI reporting supported by the current system and SRS. It is impossible to trigger SRS for uplink CSI measurement through CSI-RS resource configuration and CSI reporting.

[0221] The embodiments of the present application will be described below with reference to the accompanying drawings. The information transmission method, device, terminal and network device provided by the embodiments of the present application can be applied to a wireless communication system.

Those skilled in the art can understand that the 5G NR system is only an example and not a limitation.

[0222] See Figure 1 , Figure 1 which is a structural diagram of a network system to which the embodiments of the present application can be applied. As Figure 1 shown, it includes a user terminal 11 and a base station 12. Among them, the user terminal 11 can be a user equipment (UE). For example, it can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile internet device (MID) or a wearable device, etc. on the terminal side. It should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present application. The above base station 12 can be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems, or called Node B. It should be noted that only a 5G base station is taken as an example in the embodiments of the present application, but the specific type of the base station 12 is not limited.

[0223] The embodiments of the present application provide an information transmission method, device, terminal and network device to improve the accuracy of the calibration coefficient calculated on the network side.

[0224] Among them, the method and the device are based on the same inventive concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

[0225] As Figure 2 shown, the embodiments of the present application provide an information transmission method, which is executed by a terminal and includes:

[0226] Step S201: Determine a target second signal and parameter information of the target second signal according to the association relationship between target information and at least one second signal;

[0227] Among them, the target information includes at least one of the following: at least one first signal, at least one CSI reporting configuration information.

[0228] It should be noted that the association relationship mentioned in the embodiments of the present application can be understood as the association between the target information and the second signal, that is, the target information can be used to determine the parameter information of the second signal. Optionally, the parameter information includes the time-domain position of the target second signal and the transmission parameter, and the transmission parameter can be understood as how the terminal sends the target second signal.

[0229] For the target second signal, it only needs to obtain the associated first signal or CSI reporting configuration information based on the association relationship. The first signal or CSI reporting configuration information usually corresponds to a specific transmission time and transmission parameter. In this way, the parameter information of the target second signal can be determined based on the associated first signal or CSI reporting configuration information.

[0230] Step S202: Send the target second signal to the network device according to the parameter information;

[0231] It should be noted that the first signal mentioned in the embodiments of the present application is a reference signal sent by the network device to the terminal for downlink channel measurement. For example, the first signal can be a channel state information reference signal (CSI-RS) (which can also be referred to as a CSI-RS resource), a tracking reference signal (TRS) (which can also be referred to as a TRS resource), etc.; the second signal is a reference signal sent by the terminal to the network device for uplink channel measurement. For example, the second signal can be a sounding reference signal (SRS) (which can also be referred to as an SRS resource), etc.

[0232] It should be noted that the CSI reporting configuration information refers to the relevant configuration for the terminal to report the measurement results of the first signal. The CSI reporting configuration information may include the first signal for which the measurement results need to be reported, the resources used for reporting the results, etc. It can be understood that the CSI reporting configuration information is associated with the first signal, that is, which first signals are associated with it can be determined through a CSI reporting configuration information.

[0233] It should be noted that in the embodiments of the present application, based on the association relationship between at least one first signal and / or at least one CSI reporting configuration information and at least one second signal, the target second signal and the parameter information of the target second signal are determined to realize the transmission of the target second signal. In this way, the terminal can send the target second signal in a timely manner, avoiding the situation that the transmission time of the target second signal does not meet the calibration coefficient estimation requirements with the transmission time of the first signal and / or the reporting time of the CSI. The implementation method of the present application can ensure the accuracy of the calibration coefficient calculated by the network side.

[0234] Optionally, the association relationship is sent by the network device to the terminal. Optionally, in one implementation manner, the method further includes:

[0235] Obtain the association relationship according to the association relationship indication signaling;

[0236] Wherein, the association relationship indication signaling includes at least one of the following:

[0237] A11. Radio Resource Control (RRC) signaling;

[0238] A12. Medium Access Control Control Element (MAC CE);

[0239] A13. Downlink Control Information (DCI).

[0240] Optionally, in one implementation manner, the obtaining the association relationship according to the association relationship indication signaling includes one of the following:

[0241] A21. Obtain the association relationship between the target information and at least one second signal according to the identification information of the second signal associated with the first signal carried in the association relationship indication signaling;

[0242] It should be noted that the identification information of the second signal may include the index of the second signal, the number of the second signal, etc.

[0243] It should be noted that in this case, the association relationship indication signaling may be RRC signaling or MAC CE.

[0244] For example, when the association relationship indication signaling is RRC signaling, the RRC signaling may be the RRC signaling for CSI trigger state configuration and aperiodic first signal configuration, and the RRC signaling includes the identification information of the second signal associated with the first signal.

[0245] For example, when the association relationship indication signaling is MAC CE, optionally, the MAC CE is used to activate CSI reporting or activate first signal transmission, and the MAC CE includes the identification information of the second signal associated with the first signal.

[0246] A22. Obtain the association relationship between the target information and at least one second signal according to the identification information of the second signal associated with the CSI reporting configuration information carried in the association relationship indication signaling;

[0247] It should be noted that in this case, the association relationship indication signaling may be RRC signaling or MAC CE.

[0248] For example, when the association relationship indication signaling is RRC signaling, the RRC signaling may be the RRC signaling for CSI reporting configuration and aperiodic first signal configuration, and the RRC signaling includes the identification information of the second signal associated with the CSI reporting configuration information.

[0249] For example, when the association relationship indication signaling is a MAC CE, optionally, the MAC CE is used to activate CSI reporting or activate the first signal transmission, and the MAC CE includes the identification information of the second signal associated with the CSI reporting configuration information.

[0250] A23. Obtain the association relationship between the target information and at least one second signal according to the target information indicated in the association relationship indication signaling and the identification information of the second signal;

[0251] It should be noted that in this case, the association relationship indication signaling may be DCI.

[0252] For example, when the association relationship indication signaling is DCI, optionally, the DCI is used to trigger aperiodic CSI reporting or semi-persistent CSI reporting. The DCI includes the target information and the identification information of the second signal. The terminal can associate the two based on the target information and the identification information of the second signal to obtain the association relationship between the target information and at least one second signal.

[0253] It should be noted that by indicating the association relationship through one of the above A21 - A23, the network device can improve the flexible configuration of the association relationship.

[0254] Optionally, the association relationship indication signaling is used to implicitly or explicitly indicate whether the association relationship takes effect; optionally, according to the association relationship between the target information and at least one second signal, determining the target second signal and the parameter information of the target second signal includes:

[0255] When the association relationship between the target information and at least one second signal takes effect, determine the target second signal and the parameter information of the target second signal according to the association relationship between the target information and at least one second signal.

[0256] This situation can be understood as that the network device can indicate the association relationship through the association relationship indication signaling, but whether to use (activate) this association relationship still needs to be informed by the network device to the terminal. Only when the network device indicates that the association relationship takes effect, can the terminal determine the target second signal and the parameter information of the target second signal based on the association relationship, so as to send the target second signal based on the network requirements and ensure the timeliness and reliability of the transmission of the target second signal.

[0257] It should be noted that for the explicit indication method, it can be understood that there will be a separate indication field in the association relationship indication signaling for indicating whether the association relationship takes effect. For the implicit indication method, it can be understood that there will not be a separate indication field for indicating whether the association relationship takes effect in the association relationship indication signaling, and it can be indicated by the existence of the association relationship, that is, by whether the identification information of the second signal is included in the association relationship indication signaling. The identification information of the second signal can be indicated by a newly added indication field in the association relationship indication signaling or by reusing an existing indication field.

[0258] It should be noted that when the association relationship indication signaling is RRC signaling, MAC CE, or DCI, both implicit and explicit methods can be used to indicate whether the association relationship takes effect. Optionally, for the association relationship indication signaling, it can also be not directly indicated by the association relationship indication signaling whether the association relationship takes effect, but indicated by the network device through additional indication information. Optionally, in one implementation, the method further includes:

[0259] Receiving indication information sent by the network device, where the indication information is used to indicate whether to activate the association relationship.

[0260] Optionally, for the above A23 case, when indicating the target information and the identification information of the second signal in the association relationship indication signaling, the terminal can obtain the association relationship between the target information and at least one second signal based on the target information and the identification information of the second signal only when it determines that the association relationship needs to be activated; optionally, in the case of indicating whether to activate the association relationship through additional indication information, only when the indication information is used to indicate the activation of the association relationship, does the terminal need to associate the target information and the identification information of the second signal indicated in the association relationship indication signaling to obtain the association relationship between the target information and at least one second signal.

[0261] It should be noted that in order to ensure the smooth transmission of the target second signal, optionally, in one implementation, determining the parameter information of the target second signal includes at least one of the following:

[0262] B11. Determining the time domain position of the target second signal;

[0263] It should be noted that after determining the time domain position, the terminal will know at which positions to send the target second signal.

[0264] Optionally, in the first implementation, the specific implementation of determining the time domain position of the target second signal includes:

[0265] Determine the time domain position of the target second signal according to the time start point of the target second signal and the time slot offset.

[0266] Optionally, the time slot offset is notified by the above-mentioned association relationship indication signaling, that is, the association relationship indication signaling includes: the time slot offset of the second signal.

[0267] Optionally, the time start point includes at least one of the following:

[0268] B111. The transmission moment of the first signal associated with the target second signal;

[0269] B112. The CSI reporting moment corresponding to the first signal associated with the target second signal;

[0270] It should be noted that the above B111 and B112 are mainly applicable to the association relationship of at least one first signal and at least one second signal.

[0271] B113. The reporting moment corresponding to the CSI reporting configuration information associated with the target second signal;

[0272] B114. The transmission moment of the first signal corresponding to the CSI reporting configuration information associated with the target second signal;

[0273] It should be noted that the above B113 and B114 are mainly applicable to the association relationship of at least one CSI reporting configuration information and at least one second signal.

[0274] B115. The reception moment of the signaling activating the association relationship;

[0275] It should be noted that the above B115 is applicable to both the association relationship of at least one CSI reporting configuration information and at least one second signal and the association relationship of at least one first signal and at least one second signal.

[0276] It should be noted that the signaling activating the association relationship can be the above-mentioned RRC signaling, MAC CE, DCI, or the signaling carrying the above-mentioned indication information.

[0287] It should be noted that the first signal associated with the target second signal mentioned here can be the first signal directly indicated in the association relationship, or the first signal corresponding to the CSI reporting configuration information indicated in the association relationship.

[0288] Optionally, n is specified by the protocol (or predefined) or indicated by the network device.

[0289] It should be noted that each of the above determines only one transmission opportunity.

[0290] B22. Determine the second transmission opportunity in the first transmission opportunity as the time domain position of the target second signal, where the second transmission opportunity is the available time unit with the smallest interval from the transmission moment of the first signal or the CSI reporting moment in the first transmission opportunity;

[0291] Optionally, when the first transmission opportunity includes B211 and B212, the second transmission opportunity is the next available time unit of the received signaling that triggers aperiodic CSI or semi-persistent CSI reporting and the m-th available time unit before or after the transmission time of the first signal associated with the target second signal, and is the available time unit with the smallest interval from the transmission time of the first signal or the CSI reporting time; optionally, when the first transmission opportunity includes B211 and B213, the second transmission opportunity is the next available time unit of the received signaling that triggers aperiodic CSI or semi-persistent CSI reporting and the n-th available time unit before or after the CSI reporting time corresponding to the first signal associated with the target second signal, and is the available time unit with the smallest interval from the transmission time of the first signal or the CSI reporting time; optionally, when the first transmission opportunity includes B212 and B213, the second transmission opportunity is the m-th available time unit before or after the transmission time of the first signal associated with the target second signal and the n-th available time unit before or after the CSI reporting time corresponding to the first signal associated with the target second signal, and is the available time unit with the smallest interval from the transmission time of the first signal or the CSI reporting time.

[0296] Optionally, Y is protocol-defined (or pre-defined) or indicated by the network device.

[0297] X available time units before or after the moment of CSI reporting corresponding to the first signal associated with the target second signal, where X is an integer greater than or equal to 1;

[0298] It should be noted that the first signal associated with the target second signal mentioned here can be the first signal directly indicated in the association relationship, or the first signal corresponding to the CSI reporting configuration information indicated in the association relationship.

[0299] Optionally, X is determined by protocol convention (or predefined) or indicated by the network device.

[0300] It should be noted that in this case, there are multiple transmission opportunities determined by each of the above two items B231 and B232. When the terminal is actually in use, based on the order of the transmission opportunities, it attempts to transmit the target second signal at each transmission opportunity. As long as the target second signal is successfully transmitted at a certain transmission opportunity, the target second signal will no longer be transmitted at the subsequent other transmission opportunities.

[0301] Optionally, when the third transmission opportunity includes B231, Y available time units before or after the transmission moment of the first signal associated with the target second signal are determined as the time domain position of the target second signal; when the third transmission opportunity includes B232, X available time units before or after the moment of CSI reporting corresponding to the first signal associated with the target second signal are determined as the time domain position of the target second signal; when the third transmission opportunity includes both B231 and B232, Y available time units before or after the transmission moment of the first signal associated with the target second signal and X available time units before or after the moment of CSI reporting corresponding to the first signal associated with the target second signal are determined as the time domain position of the target second signal.

[0302] B12. Determine the transmission parameters of the first signal associated with the target second signal as the transmission parameters of the target second signal.

[0303] It should be noted that the first signal associated with the target second signal mentioned here can be the first signal directly indicated in the association relationship, or the first signal corresponding to the CSI reporting configuration information indicated in the association relationship.

[0304] Optionally, in one implementation manner, the determining the transmission parameters of the first signal associated with the target second signal as the transmission parameters of the target second signal includes at least one of the following:

[0305] B121. Determine the TCI state of the first signal associated with the target second signal as the TCI state of the target second signal;

[0306] It should be noted that by setting the TCI state of the target second signal to be the same as the TCI state of the associated first signal, the target second signal can be quasi-co-located (QCL) with the associated first signal.

[0307] B122. Determine the QCL state of the first signal associated with the target second signal as the QCL state of the target second signal;

[0308] It should be noted that by setting the QCL state of the target second signal to be the same as the QCL state of the associated first signal, the target second signal can be QCL with the associated first signal.

[0309] B123. Determine the port that receives the first signal associated with the target second signal as the port for transmitting the target second signal;

[0310] This situation can be understood as using the receiving port of the first signal associated with the target second signal as the transmitting port of the target second signal.

[0311] B124. Determine the frequency of the first signal received in association with the target second signal as the frequency for transmitting the target second signal;

[0312] This situation can be understood as using the receiving frequency of the first signal associated with the target second signal as the transmitting frequency of the target second signal.

[0313] B125. Determine the spatial filter for receiving the first signal associated with the target second signal as the spatial filter for transmitting the target second signal;

[0314] This situation can be understood as using the receiving spatial filter of the first signal associated with the target second signal as the transmitting spatial filter of the target second signal.

[0315] It should be noted that from the above description, it can be seen that the transmission parameters determined in the embodiments of the present application need to include at least one of the TCI state, QCL state, port, frequency, and spatial filter; which transmission parameters the terminal needs to use can be determined based on the corresponding methods in B121 - B125 above.

[0316] It should be noted that by transmitting the target second signal based on at least one of B121 - B125 above, the target second signal can be QCL with the first signal, the transmission time of the target second signal can meet the processing requirements of the network side, and it is ensured that the two correspond to the same transceiver antenna or antenna port.

[0317] Taking the first signal corresponding to the CSI-RS resource, the second signal corresponding to the SRS resource, and the communication between the base station and the terminal as an example, the specific application of the embodiments of the present application is illustrated as follows.

[0318] Application Scenario 1: The terminal receives a signaling from the base station configuring the association relationship between the CSI-RS resource and the SRS resource. This signaling also indicates the time slot offset of the SRS resource, and the terminal determines the target SRS and the corresponding parameter information.

[0319] In this case, the above-mentioned target information correspondingly refers to at least one CSI-RS resource, and the association relationship between the target information and at least one second signal correspondingly refers to the association relationship between at least one CSI-RS resource and at least one SRS resource. In this application scenario, it can be simply referred to as the association relationship between the CSI-RS resource and the SRS resource; the time slot offset of the second signal correspondingly refers to the time slot offset of the SRS resource.

[0320] It should be noted that the CSI-RS resources are divided into periodic CSI-RS resources, semi-persistent CSI-RS resources, and aperiodic CSI-RS resources. The SRS resources are divided into periodic SRS resources, semi-persistent SRS resources, and aperiodic SRS resources. In this application scenario, when the base station indicates the association relationship between the CSI-RS resource and the SRS resource through signaling, the CSI-RS resource is at least one of the following: periodic CSI-RS resource, semi-persistent CSI-RS resource, aperiodic CSI-RS resource; the SRS resource is at least one of the following: periodic SRS resource, semi-persistent SRS resource, aperiodic SRS resource.

[0321] The terminal obtains the association relationship between the CSI-RS resource and the SRS resource indicated by the base station according to at least one of the following methods:

[0322] Method 1:

[0323] The terminal receives the RRC signaling sent by the base station for CSI trigger state configuration and aperiodic CSI-RS resource configuration, and determines the association relationship between the CSI-RS resource and the SRS resource. This association relationship can also be expressed as the association relationship between the CSI-RS resource set and the SRS resource set. The CSI-RS resource set includes one or more CSI-RS resources, and the SRS resource set includes one or more SRS resources. When configuring the aperiodic CSI-RS, this RRC signaling also indicates the SRS resources associated with each aperiodic CSI-RS resource.

[0324] For example, in CSI-AperiodicTriggerStateList or CSI-ResourceConfig, add the associated SRS resource set identifier (associatedSRS-ResourceSetId) and slot offset (slotOffset) to indicate the associated SRS resource set ID and the slot offset of the SRS resource. The slot offset may not be named slotOffset, which is the same as the parameter name in the SRSConfig signaling, but may be distinguished by a name such as slotOffset-r19.

[0325] For example, a way to add an association in CSI-AperiodicTriggerStateList is as follows:

[0326]

[0327] The range of associatedSRS-ResourceSetId includes all SRS resource set IDs allocated to the terminal, and the range of slotOffset is from 0 to the upper limit k that meets the base station channel calculation requirements, where k is a positive integer.

[0328] The base station can indicate whether this association is effective in an explicit or implicit manner. For example, only when associatedSRS-ResourceSetId and slotOffset are included in CSI-AperiodicTriggerStateList or CSI-ResourceConfig, the terminal determines that this association is effective. The terminal can also determine whether this association is effective (or whether to activate this association) through a parameter configured by the base station in the RRC signaling, MAC CE, or DCI. For example, a new or reused unused 1-bit parameter is added. When the value of this parameter is 1, the terminal determines that this association is effective; when the value of this parameter is 0, the terminal determines that this association is not effective.

[0329] Method 2:

[0330] The base station configures not only the SRS resource set and the slot offset of the SRS resource associated with the aperiodic CSI-RS resource configuration in the RRC signaling, but also the SRS resource set and the slot offset of the SRS resource associated with the semi-persistent CSI-RS resource and the periodic CSI-RS resource configuration. The terminal determines the association between the CSI-RS resource and the SRS resource according to the content of the received RRC signaling (i.e., the identification information of the SRS resource associated with the CSI-RS resource carried in the RRC signaling).

[0331] For example, in CSI-ResourceConfig, add the associated SRS resource set (associatedSRS-ResourceSetId) and slot offset (slotOffset) to indicate the associated SRS resource set ID and the slot offset of the SRS resource.

[0332] For example, a way to add an association relationship in CSI-ResourceConfig is as follows:

[0333]

[0334]

[0335] The range of associatedSRS-ResourceSetId includes all SRS resource set IDs allocated for the terminal, and the range of slotOffset is from 0 to the upper limit k that meets the base station channel calculation requirements, where k is a positive integer.

[0336] The base station can use an explicit or implicit way to indicate whether this association relationship takes effect. For example, only when associatedSRS-ResourceSetId and slotOffset are included in CSI-ResourceConfig, the terminal determines that this association relationship takes effect. The terminal can also determine whether the association relationship takes effect (or whether to activate this association relationship) through a parameter in the RRC signaling, MAC CE signaling, or DCI signaling configuration of the base station.

[0337] Method 3:

[0338] Do not indicate the association relationship between the semi-persistent CSI-RS resource and the SRS resource through RRC signaling. The terminal receives the MAC-CE used to activate CSI reporting or activate CSI-RS transmission, and determines the association relationship between the CSI-RS resource and the SRS resource according to the signaling content (i.e., the identification information of the SRS resource associated with the CSI-RS resource carried in the MAC-CE).

[0339] For example, in the Aperiodic CSI Trigger State Subselection MAC CE signaling, configure an SRS resource set ID for all or part of the activated trigger states respectively. The terminal can use the 1-bit indication configured by the network side in the MAC CE signaling to determine whether the association relationship takes effect, or can make an implicit determination according to the way that only when an SRS resource set ID is configured for the trigger state does it indicate that the association relationship takes effect.

[0340] For example, a method for adding an association relationship in the Aperiodic CSI Trigger State Subselection MAC CE signaling is as follows Figure 3 as shown Figure 3 where T i indicates different aperiodic CSI trigger states. At the T i corresponding to all or part of the selected active trigger states, add the associated SRS resource set ID and time slot offset.

[0341] Method 4:

[0342] Instead of using RRC signaling and MAC CE to indicate the association relationship between CSI-RS resources and SRS resources, when the UE receives the DCI signaling for triggering aperiodic CSI reporting or semi-persistent CSI reporting, it determines the association relationship between CSI-RS resources and SRS resources according to the signaling content (i.e., the identification information of the SRS resources associated with the CSI-RS resources carried in the DCI). A new field is added in this DCI to indicate whether the association relationship is effective (whether the association relationship is activated). The terminal can also determine whether the association relationship is effective (whether the association relationship is activated) according to an additional indication information (such as RRC parameters) configured by the base station. If the association relationship is effective, the terminal determines that the CSI-RS resources indicated by the CSI request field in this DCI are associated with the SRS resource set indicated by the SRS request field.

[0343] For example, in the DCI signaling for triggering aperiodic CSI reporting or semi-persistent CSI reporting, a new 1-bit field is added. A bit value of 0 in this field indicates that the association relationship between the CSI-RS resources indicated by the CSI request field and the SRS resource set indicated by the SRS request field is not activated. A bit value of 1 in the new field indicates that the association relationship between the CSI-RS resources indicated by the CSI request field and the SRS resource set indicated by the SRS request field is activated.

[0344] After receiving the indication of the association relationship between CSI-RS resources and SRS resources sent by the base station, the terminal needs to determine the target SRS resources and the corresponding parameter information.

[0345] The method for the terminal to determine the transmission parameters of the target SRS resources:

[0346] When the terminal sends a target SRS resource, it uses the receiving port of the CSI-RS resource associated with the target SRS resource as the transmitting port. When the terminal sends a target SRS resource, it uses the receiving frequency of the CSI-RS resource associated with the target SRS resource as the transmitting frequency of the target SRS resource. When the terminal sends a target SRS resource, it uses the TCI state of the CSI-RS resource associated with the target SRS resource as the TCI state of the target SRS resource. When the terminal sends a target SRS resource, it uses the receiving spatial filter for receiving the CSI-RS resource associated with the target SRS resource as the transmitting spatial filter for the target SRS resource, so that the two are QCL.

[0347] It should be noted that when the receiving spatial filters of the CSI-RS resources of multiple TRPs are different, the terminal can use different transmitting spatial filters for each SRS resource in the associated SRS resource set, and each transmitting spatial filter corresponds to the receiving spatial filter of the CSI-RS resource associated with the SRS resource. In this way, the CSI-RS resource sent by each TRP and the SRS resource received by the TRP are QCL.

[0348] For example, the terminal configures 4 SRS resource sets, which are respectively associated with the CSI-RS resource sets of 4 TRPs. The terminal uses the receiving spatial filters of the CSI-RS resource sets of each TRP as the transmitting spatial filters of the associated SRS resource sets. Another example is that the terminal configures an SRS resource set, and there are 4 SRS resources in this SRS resource set, which are respectively associated with the CSI-RS resource sets of 4 TRPs. The terminal uses the receiving spatial filters of the CSI-RS resource sets of each TRP as the transmitting spatial filters of the associated SRS resources.

[0349] The way for the terminal to determine the time domain position for transmitting the target SRS resource is as follows:

[0350] Determine the time domain position of the target SRS resource according to the time start point and slot offset of the target SRS resource.

[0351] It can be understood that the terminal performs SRS transmission at the slot offset position specified by the base station according to the slot offset of the SRS resource indicated by the base station.

[0352] The starting point for calculating the slot offset of the SRS resource (i.e., the time start point of the target SRS resource) can be at least one of the following: the transmission time of the associated CSI-RS resource, the CSI reporting time corresponding to the associated CSI-RS resource, and the reception time of the signaling activating the association relationship.

[0353] It should be noted that the reason why the starting point for calculating the time slot offset of the SRS resource is at least one of the above is that there is currently no correlation between the SRS transmission time and the CSI-RS transmission time or CSI reporting time in the protocol. In order to make the time of CSI-RS transmission or CSI reporting meet the processing requirements of the network side with respect to the SRS transmission time for estimating uplink channel information, it is necessary to make the SRS transmission time related to the associated CSI-RS transmission or CSI reporting time. Therefore, the starting point for calculating the time slot offset of the above SRS resource is selected.

[0354] Specifically, the specific timing of SRS transmission in this application scenario:

[0355] 1. The terminal receives a signaling that configures the correlation between the CSI-RS resource and the SRS resource from the base station. The terminal establishes the correlation between the CSI-RS resource and the SRS resource according to the signaling and obtains the SRS time slot offset.

[0356] 2. The terminal determines the starting point for calculating the time slot offset of the SRS resource according to the signaling that configures the correlation between the CSI-RS resource and the SRS resource or according to other signaling from the base station. When the starting point for calculating the time slot offset of the SRS resource is reached, the terminal starts timing.

[0357] 3. At the moment that is the time slot offset of the SRS resource indicated by the base station from the starting point, the terminal transmits the to-be-transmitted SRS determined according to the correlation between the CSI-RS resource and the SRS resource.

[0358] Application Scenario 2: The terminal receives a signaling that configures the correlation between the CSI reporting configuration information and the SRS resource from the base station. This signaling also indicates the time slot offset of the SRS resource, and the terminal determines the target SRS and the corresponding parameter information

[0359] In this case, the above-mentioned target information correspondingly refers to at least one CSI reporting configuration information, and the correlation between the target information and at least one second signal correspondingly refers to the correlation between at least one CSI reporting configuration information and at least one SRS resource. In this application scenario, it can be simply referred to as the correlation between the CSI reporting configuration information and the SRS resource; the time slot offset of the second signal correspondingly refers to the time slot offset of the SRS resource.

[0360] The terminal obtains the correlation between the CSI-RS resource and the SRS resource indicated by the base station according to at least one of the following methods:

[0361] Method 1:

[0362] The terminal receives the RRC signaling sent by the base station for CSI reporting configuration information and aperiodic CSI-RS resource configuration, and determines the association relationship between the CSI reporting configuration information and the SRS resources. This association relationship can also be expressed as the association relationship between the CSI-RS reporting configuration information and the SRS resource set, and the SRS resource set includes one or more SRS resources. When configuring the CSI reporting configuration information, the RRC signaling also indicates the SRS resources associated with each CSI reporting configuration information.

[0363] For example, add the associated SRS resource set and slot offset in the CSI-AperiodicTriggerStateList or CSI-ReportConfig.

[0364] For example, a way to add the association relationship in the CSI-ReportConfig is as follows:

[0365]

[0366]

[0367] The range of the associatedSRS-ResourceSetId includes all SRS resource set IDs allocated for this terminal, and the range of the slotOffset is from 0 to the upper limit k that meets the base station channel calculation requirements, where k is a positive integer.

[0368] The base station uses an explicit or implicit method to indicate whether this association relationship takes effect. For example, only when the associatedSRS-ResourceSetId and slotOffset are included in the CSI-AperiodicTriggerStateList or CSI-ReportConfig, the terminal determines that this association relationship takes effect. The terminal can also determine whether this association relationship takes effect (or whether to activate this association relationship) through a parameter configured by the base station in the RRC signaling, MAC CE, or DCI. For example, a new or reused unused 1-bit parameter is added. When the value of this parameter is 1, the terminal determines that this association relationship takes effect, and when the value of this parameter is 0, the terminal determines that this association relationship does not take effect.

[0369] Method 2:

[0370] The base station does not indicate the association relationship between the CSI reporting configuration information and the SRS resources through RRC signaling. The terminal receives the MAC-CE for activating CSI reporting and determines the association relationship between the CSI reporting configuration information and the SRS resources according to the signaling content (i.e., the identification information of the SRS resources associated with the CSI-RS reporting configuration information carried in the MAC-CE).

[0371] For example, in the SP CSI reporting on PUCCH Activation / Deactivation MAC CE signaling, a SRS resource set ID is configured for all or part of the activated CSI reporting configuration information. The base station can use a 1-bit in the MAC CE signaling to indicate whether the association relationship is effective, or can perform implicit indication according to the method that the association relationship is indicated to be effective only when a SRS resource set ID is configured for the CSI association relationship.

[0372] For example, a way to add an association relationship in the SP CSI reporting on PUCCH Activation / Deactivation MAC CE signaling is as Figure 4 shown Figure 4 in S i indicates different semi-persistent CSI reporting configuration activation states. An associated SRS resource set and a slot offset are added at the S i corresponding to all or part of the selected trigger states for activation.

[0373] Method 3:

[0374] The base station does not indicate the association relationship between the CSI-RS reporting configuration information and the SRS resources through RRC signaling and MAC CE. The terminal receives the DCI signaling for triggering aperiodic CSI reporting or semi-persistent CSI reporting, and determines the association relationship between the CSI reporting configuration information and the SRS resources according to the signaling content (i.e., the identification information of the SRS resources associated with the CSI-RS reporting configuration information carried in the DCI). A new field is added in this DCI to indicate whether the association relationship is effective (whether the association relationship is activated). The terminal can also judge whether the association relationship is effective (whether the association relationship is activated) according to an additional indication information (such as an RRC parameter) configured by the base station. If the association relationship is activated, the CSI reporting configuration information indicated by the CSI request field in this DCI is associated with the SRS resource set indicated by the SRS request field.

[0375] After the terminal receives the indication of the association relationship between the CSI-RS reporting configuration information and the SRS resource sent by the base station, it needs to determine the target SRS resource and the corresponding parameter information.

[0376] The method for the terminal to determine the transmission parameters of the target SRS resource:

[0377] When the terminal sends the target SRS resource, it uses the receiving port of the CSI-RS resource corresponding to the CSI-RS reporting configuration information associated with the target SRS resource as the transmitting port. When the terminal sends the target SRS resource, it uses the receiving frequency of the CSI-RS resource corresponding to the CSI-RS reporting configuration information associated with the target SRS resource as the transmitting frequency of the target SRS resource. When the terminal sends the target SRS resource, it uses the TCI state of the CSI-RS resource corresponding to the CSI-RS reporting configuration information associated with the target SRS resource as the TCI state of the target SRS resource. When the terminal sends the target SRS resource, it uses the receiving spatial filter for receiving the CSI-RS resource corresponding to the CSI-RS reporting configuration information associated with the target SRS resource as the transmitting spatial filter for the target SRS resource, so that the two are QCL.

[0378] It should be noted that when the receiving spatial filters of the CSI-RS resources of multiple TRPs are different, the terminal can use different transmitting spatial filters for each SRS resource in the associated SRS resource set, and each transmitting spatial filter corresponds to the receiving spatial filter of the CSI-RS resource associated with the SRS resource. In this way, the CSI-RS resource sent by each TRP and the SRS resource received by the TRP are QCL.

[0379] For example, the terminal configures 4 SRS resource sets, which are respectively associated with the CSI reporting settings of 4 TRPs. The terminal respectively uses the receiving spatial filters of the CSI-RS resources corresponding to the CSI reporting settings of each TRP as the transmitting spatial filters of the associated SRS resource sets. Another example is that the terminal configures an SRS resource set, and there are 4 SRS resources in this SRS resource set, which are respectively associated with the CSI reporting settings of 4 TRPs. The terminal respectively uses the receiving spatial filters of the CSI-RS resources corresponding to the CSI reporting settings of each TRP as the transmitting spatial filters of the associated SRS resources.

[0380] The method for the terminal to determine the time domain position of transmitting the target SRS resource is:

[0381] Determine the time domain position of the target SRS resource according to the time start point and slot offset of the target SRS resource.

[0382] It can be understood that the terminal performs SRS transmission at the time slot offset position specified by the base station according to the time slot offset of the SRS resource indicated by the base station.

[0383] The starting point for calculating the time slot offset of the SRS resource (i.e., the time starting point of the target SRS resource) can be at least one of the following: the reporting moment corresponding to the associated CSI reporting configuration information, the CSI-RS transmission moment corresponding to the associated CSI reporting configuration information, and the signaling reception moment for activating the association relationship.

[0384] Specifically, the specific timing of SRS transmission in this application scenario:

[0385] 1. The terminal receives a signaling from the network side that configures the association relationship between the CSI reporting configuration information and the SRS resource. The UE establishes the association relationship between the CSI reporting configuration information and the SRS resource according to the signaling and obtains the time slot offset of the SRS resource.

[0386] 2. The terminal determines the starting point for calculating the time slot offset of the SRS resource according to the signaling that configures the association relationship between the CSI reporting configuration information and the SRS resource or according to other signaling from the base station. When the starting point for calculating the time slot offset of the SRS resource is reached, the terminal starts timing.

[0387] 3. At the moment that is the time slot offset of the SRS resource indicated by the base station from the starting point, the terminal transmits the to-be-transmitted SRS determined according to the association relationship between the CSI reporting configuration information and the SRS resource.

[0388] Application scenario three: The terminal receives a signaling from the base station that configures the association relationship between the CSI-RS resource and the SRS resource. This signaling does not indicate the time slot offset of the SRS resource, and the terminal determines the target SRS and the corresponding parameter information

[0389] In this case, the above-mentioned target information correspondingly refers to at least one CSI-RS resource, and the association relationship between the target information and at least one second signal correspondingly refers to the association relationship between at least one CSI-RS resource and at least one SRS resource. In this application scenario, it can be simply referred to as the association relationship between the CSI-RS resource and the SRS resource.

[0390] The method for the terminal to determine the association relationship between the CSI-RS resource and the SRS resource indicated by the base station according to the signaling can refer to Application scenario one and will not be elaborated here; however, in this case, the base station no longer indicates the time slot offset of the SRS resource.

[0391] The method for the terminal to determine the transmission parameters of the target SRS resource can refer to Application scenario one and will not be elaborated here.

[0392] The terminal determines the transmission time of the CSI-RS resource in the association relationship between the CSI-RS resource and the SRS resource indicated by the base station according to the signaling, and the reporting time corresponding to the CSI measured by the CSI-RS resource. On this basis, the terminal can determine the time domain position of transmitting the SRS resource and transmit the SRS according to at least one of the following methods, and the corresponding base station listens at the corresponding time domain position:

[0393] E11. If the terminal receives the DCI signaling triggering the aperiodic or semi-persistent CSI reporting, it transmits the SRS through the target SRS resource in the next available time unit;

[0394] E12. The terminal transmits the SRS through the target SRS resource in the mth available time unit after or before the CSI-RS transmission time slot / symbol according to the obtained CSI-RS transmission time;

[0395] E13. The terminal transmits the SRS through the target SRS resource in the nth available time unit after or before the CSI reporting time slot / symbol according to the CSI reporting time;

[0396] E14. The terminal calculates all available time units in the above three cases of E11 - E13, and uses the available time unit closest to the CSI-RS transmission time or the CSI reporting time to transmit the SRS through the target SRS resource;

[0397] E15. The terminal attempts to transmit the SRS through the target SRS resource within Y available time units after or before the CSI-RS transmission time slot / symbol, and stops transmitting the SRS after successful transmission;

[0398] E16. The terminal attempts to transmit the SRS through the target SRS resource within X available time units after or before the CSI reporting time slot / symbol, and stops transmitting the SRS after successful transmission.

[0399] Specifically, the specific timing of SRS transmission in this application scenario:

[0400] 1. The terminal receives the signaling from the base station configuring the association relationship between the CSI-RS resource and the SRS resource, and the terminal establishes the association relationship between the CSI-RS resource and the SRS resource according to the signaling.

[0401] 2. The terminal determines the transmission time of the CSI-RS resource in the association relationship between the CSI-RS resource and the SRS resource indicated by the base station according to the signaling configuring the association relationship between the CSI-RS resource and the SRS resource or according to other signaling from the base station, and the reporting time corresponding to the CSI measured by the CSI-RS resource.

[0402] 3. According to different ways for the terminal to determine the time domain position of the transmitted SRS resource, the following possible timing relationships exist:

[0403] Case 1: If the terminal receives the DCI signaling that triggers the aperiodic or semi-persistent CSI report, it sends the SRS in the next available time unit.

[0404] The timing relationship at this time is: The terminal first receives the DCI signaling that triggers the aperiodic or semi-persistent CSI report, calculates the next available time unit, and sends the SRS in this time unit.

[0405] Case 2: The terminal sends the SRS in the m-th available time unit after or before the CSI-RS transmission time slot / symbol according to the obtained CSI-RS transmission time.

[0406] If it is selected to send the associated SRS in the m-th available time unit before the obtained CSI-RS transmission time slot / symbol, the timing relationship at this time is: The terminal first receives the signaling indicating the CSI-RS transmission from the base station and obtains the CSI-RS transmission time according to the signaling. Then the terminal sends the SRS in the m-th available time unit before the obtained CSI-RS transmission time slot / symbol. Then the terminal receives the CSI-RS sent by the base station.

[0407] If it is selected to send the SRS in the m-th available time unit after the obtained CSI-RS transmission time slot / symbol, the timing relationship at this time is: The terminal first receives the signaling indicating the CSI-RS transmission from the base station and obtains the CSI-RS transmission time according to the signaling. Then the terminal receives the CSI-RS sent by the base station. Then the terminal sends the associated SRS in the m-th available time unit after the obtained CSI-RS transmission time slot / symbol.

[0408] Case 3: The terminal sends the SRS in the n-th available time unit after or before the CSI report time slot / symbol according to the CSI report time.

[0409] If it is selected to send the associated SRS in the m-th available time unit before the obtained CSI report time slot / symbol, the timing relationship at this time is: The terminal first receives the signaling indicating the CSI report from the base station and obtains the CSI report time according to the signaling. Then, the terminal sends the associated SRS in the m-th available time unit before the obtained CSI report time slot / symbol. Then, the terminal performs the CSI report.

[0410] If it is selected to transmit the associated SRS at the m-th available time unit after the obtained CSI reporting time slot / symbol, the timing relationship at this time is as follows: The terminal first receives the signaling indicating CSI reporting from the base station, and obtains the CSI reporting time according to the signaling. Then, the terminal performs CSI reporting. Then, the terminal transmits the associated SRS at the m-th available time unit after the CSI reporting time slot / symbol.

[0411] Case 4: The terminal calculates all available time units in the above three cases, and selects the available time unit closest to the CSI-RS transmission time or the CSI reporting time to transmit the SRS;

[0412] If the selected SRS transmission timing is the closest to the CSI-RS transmission time and before the CSI-RS transmission time, the timing relationship at this time is as follows: The terminal first receives the signaling indicating CSI-RS transmission from the base station, and obtains the CSI-RS transmission time according to the signaling. Then, the terminal transmits the associated SRS at the first available time unit before the obtained CSI-RS transmission time slot / symbol. Then, the terminal receives the CSI-RS sent by the base station.

[0413] If the selected SRS transmission timing is the closest to the CSI-RS transmission time and after the CSI-RS transmission time, the timing relationship at this time is as follows: The terminal first receives the signaling indicating CSI-RS transmission from the base station, and obtains the CSI-RS transmission time according to the signaling. Then, the terminal receives the CSI-RS sent by the base station. Then, the terminal transmits the SRS at the first available time unit after the obtained CSI-RS transmission time slot / symbol.

[0414] If the selected SRS transmission timing is the closest to the CSI reporting time and before the CSI reporting time, the timing relationship at this time is as follows: The terminal first receives the signaling indicating CSI reporting from the base station, and obtains the CSI reporting time according to the signaling. Then, the terminal transmits the SRS at the first available time unit before the obtained CSI reporting time slot / symbol. Then, the terminal performs CSI reporting.

[0415] If the selected SRS transmission timing is the closest to the CSI reporting time and after the CSI reporting time, the timing relationship at this time is as follows: The terminal first receives the signaling indicating CSI reporting from the base station, and obtains the CSI reporting time according to the signaling. Then, the terminal performs CSI reporting. Then, the terminal transmits the SRS at the first available time unit after the CSI reporting time slot / symbol.

[0416] Case 5: The terminal attempts to transmit the SRS within m available time units after or before the CSI-RS transmission time slot / symbol, and will not transmit again after successful transmission;

[0417] If it is selected to attempt to transmit SRS within m available time units before the obtained CSI-RS transmission time slot / symbol, no further transmission is made after a successful transmission. The timing relationship at this time is as follows: The terminal first receives the signaling indicating the CSI-RS transmission from the base station and obtains the CSI-RS transmission time according to the signaling. Then the terminal attempts to transmit SRS within m available time units before the obtained CSI-RS transmission time slot / symbol until the transmission is successful or all available time units are attempted. Then the terminal receives the CSI-RS sent by the network side.

[0418] If it is selected to attempt to transmit SRS within m available time units after the obtained CSI-RS transmission time slot / symbol, no further transmission is made after a successful transmission. The timing relationship at this time is as follows: The terminal first receives the signaling indicating the CSI-RS transmission from the base station and obtains the CSI-RS transmission time according to the signaling. Then the terminal receives the CSI-RS sent by the base station. Then the terminal attempts to transmit the associated SRS within m available time units after the obtained CSI-RS transmission time slot / symbol until the transmission is successful or all available time units are attempted.

[0419] Case 6: The terminal transmits SRS within n available time units after or before the CSI reporting time slot / symbol, and no further transmission is made after a successful transmission.

[0420] If it is selected to attempt to transmit using the associated SRS within m available time units before the obtained CSI reporting time slot / symbol, no further transmission is made after a successful transmission. The timing relationship at this time is as follows: The terminal first receives the signaling indicating the CSI reporting from the base station and obtains the CSI reporting time according to the signaling. Then the terminal attempts to transmit the associated SRS within m available time units before the obtained CSI reporting time slot / symbol until the transmission is successful or all available time units are attempted. Then the terminal performs CSI reporting.

[0421] If it is selected to attempt to transmit SRS within m available time units after the obtained CSI reporting time slot / symbol, no further transmission is made after a successful transmission. The timing relationship at this time is as follows: The terminal first receives the signaling indicating the CSI reporting from the base station and obtains the CSI reporting according to the signaling. Then the terminal performs CSI reporting. Then the terminal attempts to transmit SRS within m available time units after the CSI reporting time slot / symbol until the transmission is successful or all available time units are attempted.

[0422] Application Case 4: The terminal receives the signaling from the base station configuring the association relationship between the CSI reporting configuration information and the SRS resource. This signaling does not indicate the time slot offset of the SRS resource, and the terminal determines the target SRS and the corresponding parameter information

[0423] In this case, the above-mentioned target information correspondingly refers to at least one CSI reporting configuration information, and the association relationship between the target information and at least one second signal correspondingly refers to the association relationship between at least one CSI reporting configuration information and at least one SRS resource. In this application scenario, it can be simply referred to as the association relationship between the CSI reporting configuration information and the SRS resource.

[0424] For the method by which the terminal determines the association relationship between the CSI-RS reporting configuration information and the SRS resource indicated by the base station according to the signaling, refer to Application Scenario 2, which will not be elaborated here. However, in this case, the base station no longer indicates the time slot offset of the SRS resource.

[0425] For the way by which the terminal determines the transmission parameters of the target SRS resource, refer to Application Scenario 2, which will not be elaborated here.

[0426] The terminal determines the CSI reporting moment in the association relationship between the CSI reporting configuration information and the SRS resource indicated by the network side according to the signaling, as well as the CSI-RS resource transmission moment corresponding to this CSI reporting configuration information. On this basis, the terminal can determine the time domain position of the transmitted SRS resource and send the SRS according to at least one of the following methods. Accordingly, the base station listens at the corresponding time domain position:

[0427] E21: If the terminal receives the DCI signaling that triggers the aperiodic or semi-persistent CSI reporting, send the SRS through the target SRS resource in the next available time unit;

[0428] E22: The terminal sends the SRS through the target SRS resource in the mth available time unit after or before the CSI-RS transmission time slot / symbol according to the obtained CSI-RS transmission moment;

[0429] E23: The terminal sends the SRS through the target SRS resource in the nth available time unit after or before the CSI reporting time slot / symbol according to the CSI reporting moment;

[0430] E24: The terminal calculates all available time units in the above three cases of E21 - E23, and selects the available time unit closest to the CSI-RS transmission moment or the CSI reporting moment to send the SRS through the target SRS resource;

[0431] E25: The terminal attempts to send the SRS through the target SRS resource within Y available time units after or before the CSI-RS transmission time slot / symbol, and will not send the SRS anymore after successful transmission;

[0432] E26: The terminal attempts to send the SRS through the target SRS resource within X available time units after or before the CSI reporting time slot / symbol, and will not send the SRS anymore after successful transmission.

[0433] It should be noted here that the main difference between Application Case 4 and Application Case 3 is that in Application Case 4, the association relationship between CSI reporting configuration information and SRS resources is established, while in Application Case 3, the association relationship between CSI-RS resources and SRS resources is established.

[0434] Specifically, the specific timing of SRS transmission in this application case is as follows:

[0435] 1. The terminal receives a signaling that the base station configures the association relationship between CSI reporting configuration information and SRS resources, and the terminal establishes the association relationship between CSI reporting configuration information and SRS resources according to the signaling.

[0436] 2. The terminal determines the CSI reporting moment in the established association relationship between CSI reporting configuration information and SRS resources indicated by the base station according to the signaling that configures the association relationship between CSI reporting configuration information and SRS resources or according to other signaling of the base station, and the transmission moment of the CSI-RS corresponding to the CSI reporting setting.

[0437] 3. For the different ways for the terminal to determine the time domain position of transmitting the SRS resource, refer to the specific timing relationship of Application Case 3, which will not be elaborated here.

[0438] It should be noted that preferably, the embodiment of the present application proposes a triggering method for SRS based on the association relationship between CSI-RS resources or CSI reporting configuration information and SRS resources. According to the embodiment of the present application, the terminal can, according to the configuration of the network side, make the time of CSI-RS transmission or CSI reporting satisfy the processing requirements of the network side for estimating the uplink channel information, and ensure that the two correspond to the same transmission parameters, thereby ensuring that the two correspond to the same TCI state or QCL state; in this way, the accuracy of the calibration coefficient calculated by the network side is ensured.
