Abstract
Description
Information transmission method, device, terminal and network equipment
[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on December 22, 2023, with application number 202311782177.7 and application name “Information Transmission Method, Device, Terminal and Network Equipment,” the entire contents of which are incorporated by reference into this disclosure. Technical Field
[0002] The present disclosure relates to the field of communication technology, and in particular to an information transmission method, apparatus, terminal, and network equipment. Background Art
[0003] For coherent joint transmission (CJT), under the assumption of non-ideal reciprocity, the uplink and downlink channels between the user equipment (UE) and multiple coordination points are no longer transposed of each other. Accordingly, the precoding codewords obtained by the network through uplink channel estimation no longer match the actual downlink channel. The UE can report the phase difference between the coordination points to the network. The network calculates the calibration coefficient based on the phase difference to pre-compensate the uplink channel and then determines the downlink precoding matrix for downlink transmission. The key to correctly estimating the calibration coefficient on the network side is to obtain accurate uplink and downlink channel information. However, the current protocol mechanism cannot ensure that the reference signal used for downlink channel measurement (such as the Channel State Information Reference Signal (CSI-RS)) is sent or the Channel State Information (CSI) is reported (corresponding to downlink channel information estimation) at a sufficiently close time to the reference signal used for estimating uplink channel measurement (such as the Sounding Reference Signal (SRS)), or that the two correspond to the same transmission parameters, resulting in inaccurate calibration coefficients calculated by the network side.

[0207] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.
[0208] The terms "first," "second," and the like in the specification and claims of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein may be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products, or apparatus.
[0209] In the embodiments of the present disclosure, the term "and / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship. In the embodiments of the present disclosure, the term "plurality" refers to two or more, and other quantifiers are similar.
[0210] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.
[0211] The relevant concepts mentioned in this disclosure are briefly described below.
[0212] 1. CJT transmission
[0213] Rel-18 standardizes CJT technology and supports coherent transmission of up to 4 transmission points (Transmission and Reception Point, TRP). Assume that the channels of the 4 TRPs and UEs are H i , the signal y received by the UE can be expressed as: y=[H1 H2 H3 H4]Wx+n
[0214] Where W is the precoding codeword for the joint transmission of the four TRPs, x is the signal sent by each TRP, and n is the receiver noise. As can be seen from the above formula, in CJT transmission, the precoding codewords of all TRPs can be expressed as a joint matrix, that is, the precoding codeword is jointly determined based on the channel conditions of all TRPs.
[0215] 2. CSI-RS Resource Configuration
[0216] The current system supports both CSI-RS and beamformed CSI-RS for CSI measurement. During CSI measurement, the network can configure a CSI-RS resource setting for the UE, which includes one or more CSI-RS resource sets, each of which contains one or more CSI-RS resources.
[0217] 3. CSI reporting
[0218] The current system supports both beam measurement reporting and CSI measurement reporting. In CSI reporting, the network can configure a CSI reporting setting for the UE. Each CSI reporting setting is associated with one or more CSI resource sets. Each CSI resource set contains one or more CSI-RS resources. The UE reports based on the reporting amount configured by the network.
[0219] 4. SRS trigger
[0220] The current system supports CSI measurement SRS and beam management SRS. In uplink CSI measurement, the network can configure one or more SRS resource sets for the UE. Each SRS resource set contains one or more SRS resources. The UE triggers SRS transmission based on the signaling configured by the network.
[0221] The CSI-RS resource configuration and CSI reporting supported by the current system are not associated with SRS, and therefore SRS cannot be triggered for uplink CSI measurement through CSI-RS resource configuration and CSI reporting.
[0222] The following describes embodiments of the present disclosure in conjunction with the accompanying drawings. The information transmission method, apparatus, terminal, and network equipment provided by the embodiments of the present disclosure can be applied to a wireless communication system. The wireless communication system can be a system using fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will appreciate that the 5G NR system is merely an example and not a limitation.
[0223] Referring to FIG1 , FIG1 is a structural diagram of a network system applicable to an embodiment of the present disclosure. As shown in FIG1 , the network system includes a user terminal 11 and a base station 12. The user terminal 11 may be a user equipment (UE), such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile internet device (MID), or a wearable device. It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present disclosure. The base station 12 may be a base station of 5G or later versions (e.g., gNB, 5G NR NB), or a base station in other communication systems, or referred to as a node B. It should be noted that in the embodiment of the present disclosure, only a 5G base station is used as an example, but the specific type of the base station 12 is not limited.
[0224] The embodiments of the present disclosure provide an information transmission method, apparatus, terminal, and network device to improve the accuracy of calibration coefficients calculated on the network side.
[0225] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.
[0226] As shown in FIG2 , an embodiment of the present disclosure provides an information transmission method, which is executed by a terminal and includes:
[0227] Step S201: determining a target second signal and parameter information of the target second signal according to an association relationship between target information and at least one second signal;
[0228] The target information includes at least one of the following: at least one first signal and at least one CSI reporting configuration information.
[0229] It should be noted that the association relationship mentioned in the embodiments of the present disclosure can be understood as an association between the target information and the second signal, that is, the target information can be used to determine parameter information of the second signal. In some embodiments, the parameter information includes the time domain position and transmission parameters of the target second signal. The transmission parameters can be understood as the method used by the terminal to transmit the target second signal.
[0230] For the target second signal, it is necessary to obtain the first signal or CSI reporting configuration information associated with it based on the association relationship. The first signal or CSI reporting configuration information usually corresponds to a specific sending time and transmission parameters, so that the parameter information of the target second signal can be determined based on the associated first signal or CSI reporting configuration information.
[0231] Step S202: sending the target second signal to the network device according to the parameter information;
[0232] It should be noted that the first signal mentioned in the embodiment of the present disclosure is a reference signal sent by a network device to a terminal for downlink channel measurement. For example, the first signal may be a channel state information reference signal (CSI-RS) (also referred to as a CSI-RS resource), a tracking reference signal (TRS) (also referred to as a TRS resource), etc.; the second signal is a reference signal sent by the terminal to a network device for uplink channel measurement. For example, the second signal may be a sounding reference signal (SRS) (also referred to as an SRS resource), etc.
[0233] It should be noted that the CSI reporting configuration information refers to the relevant configuration for reporting the measurement results of the first signal for the terminal. The CSI reporting configuration information may include the first signal for which the measurement results need to be reported, the resources used for the reporting results, etc. It can be understood that the CSI reporting configuration information is associated with the first signal, that is, through a CSI reporting configuration information, it is possible to determine which first signals are associated with it.
[0234] It should be noted that the embodiment of the present disclosure determines the target second signal and the parameter information of the target second signal 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 to realize the sending of the target second signal, so as to enable the terminal to send the target second signal in a timely manner, and avoid the sending time of the target second signal and the sending time of the first signal and / or the reporting time of the CSI not meeting the calibration coefficient estimation requirements. The implementation method of the present disclosure can ensure the accuracy of the calibration coefficient calculated on the network side.
[0235] In some embodiments, the association relationship is sent by the network device to the terminal. In some embodiments, the method further includes:
[0236] Acquiring the association relationship according to the association relationship indication signaling;
[0237] The association relationship indication signaling includes at least one of the following:
[0238] A11, Radio Resource Control (RRC) signaling;
[0239] A12, Media Access Control Control Element (MAC CE);
[0240] A13. Downlink Control Information (DCI).
[0241] In some embodiments, obtaining the association relationship according to the association relationship indication signaling includes one of the following:
[0242] A21. Acquire an association relationship between target information and at least one second signal according to identification information of the second signal associated with the first signal carried in the association relationship indication signaling;
[0243] It should be noted that the identification information of the second signal may include an index of the second signal, a number of the second signal, etc.
[0244] It should be noted that, in this case, the association relationship indication signaling may be RRC signaling or MAC CE.
[0245] For example, when the association relationship indication signaling is RRC signaling, the RRC signaling may be RRC signaling for configuring the CSI triggering state and the aperiodic first signal, and the RRC signaling includes identification information of the second signal associated with the first signal.
[0246] For example, when the association relationship indication signaling is a MAC CE, in some embodiments, the MAC CE is used to activate CSI reporting or activate first signal transmission, and the MAC CE includes identification information of the second signal associated with the first signal.
[0247] A22. Acquire an association relationship between the target information and the 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;
[0248] It should be noted that, in this case, the association relationship indication signaling may be RRC signaling or MAC CE.
[0249] For example, when the association relationship indication signaling is RRC signaling, the RRC signaling may be RRC signaling of CSI reporting configuration and aperiodic first signal configuration, and the RRC signaling includes identification information of the second signal associated with the CSI reporting configuration information.
[0250] For example, when the association relationship indication signaling is a MAC CE, in some embodiments, the MAC CE is used to activate CSI reporting or activate first signal transmission, and the MAC CE includes identification information of the second signal associated with the CSI reporting configuration information.
[0251] A23. Acquire an association relationship between the target information and at least one second signal according to the identification information of the target information and the second signal indicated in the association relationship indication signaling;
[0252] It should be noted that, in this case, the association relationship indication signaling may be DCI.
[0253] For example, when the association relationship indication signaling is DCI, in some embodiments, the DCI is used to trigger non-periodic CSI reporting or semi-continuous CSI reporting, and the DCI includes identification information of the target information and 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.
[0254] It should be noted that the network device can improve the flexible configuration of the association relationship by indicating the association relationship through one of the above-mentioned A21-A23.
[0255] In some embodiments, the association relationship indication signaling is used to implicitly or explicitly indicate whether the association relationship is effective; in some embodiments, determining the target second signal and parameter information of the target second signal based on the association relationship between the target information and at least one second signal includes:
[0256] When the association relationship between the target information and the at least one second signal is effective, the target second signal and parameter information of the target second signal are determined according to the association relationship between the target information and the at least one second signal.
[0257] This situation can be understood as the network device can indicate the association relationship through association relationship indication signaling, but whether to use (activate) the association relationship still requires the network device to inform the terminal. Only when the network device indicates that the association relationship is effective, 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 network requirements, thereby ensuring the timeliness and reliability of the sending of the target second signal.
[0258] 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 to indicate whether the association relationship is effective. For the implicit indication method, it can be understood that there will not be a separate indication field in the association relationship indication signaling to indicate whether the association relationship is effective. It can be indicated by whether the association relationship exists, that is, by whether the association relationship indication signaling includes the identification information of the second signal. 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 for indication.
[0259] It should be noted that when the association relationship indication signaling is RRC signaling, MAC CE, or DCI, it can be indicated implicitly or explicitly whether the association relationship is effective. In some embodiments, for the association relationship indication signaling, it is also possible not to directly indicate whether the association relationship is effective through the association relationship indication signaling, but the network device may indicate it through additional indication information. In some embodiments, the method further includes:
[0260] Indication information sent by a network device is received, where the indication information is used to indicate whether to activate the association relationship.
[0261] In some embodiments, for the above-mentioned situation A23, when the identification information of the target information and the second signal is indicated in the association relationship indication signaling, the terminal can only obtain the association relationship between the target information and at least one second signal based on the identification information of the target information and the second signal if it determines that the association relationship needs to be activated; in some embodiments, when additional indication information is used to indicate whether to activate the association relationship, the terminal needs to associate the two based on the identification information of the target information and 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 only if the indication information is used to indicate the activation of the association relationship.
[0262] It should be noted that, in order to ensure smooth transmission of the target second signal, in some embodiments, determining the parameter information of the target second signal includes at least one of the following:
[0263] B11. Determine the time domain position of the target second signal;
[0264] It should be noted that after determining the time domain position, the terminal knows at which positions the target second signal needs to be sent.
[0265] In some embodiments, under the first implementation, the specific implementation of determining the time domain position of the target second signal includes:
[0266] Determining a time domain position of the target second signal according to a time starting point and a time slot offset of the target second signal;
[0267] In some embodiments, 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.
[0268] In some embodiments, the time starting point includes at least one of the following:
[0269] B111, the sending time of the first signal associated with the target second signal;
[0270] B112, CSI reporting time corresponding to the first signal associated with the target second signal;
[0271] It should be noted that the above B111 and B112 are mainly applicable to the association relationship between at least one first signal and at least one second signal.
[0272] B113, a reporting time corresponding to the CSI reporting configuration information associated with the target second signal;
[0273] B114. a sending time of the first signal corresponding to the CSI reporting configuration information associated with the target second signal;
[0274] It should be noted that the above B113 and B114 are mainly applicable to the association relationship between at least one CSI reporting configuration information and at least one second signal.
[0275] B115: the time of receiving the signaling for activating the association relationship;
[0276] It should be noted that the above-mentioned B115 is applicable to both the association relationship between at least one CSI reporting configuration information and at least one second signal and the association relationship between at least one first signal and at least one second signal.
[0277] It should be noted that the signaling for activating the association relationship may be the RRC signaling, MAC CE, DCI mentioned above, or may be the signaling that carries the indication information mentioned above.

[0289] In some embodiments, n is a protocol agreement (or predefined) or a network device indication.
[0290] It should be noted that each of the above items determines only one sending opportunity.
[0291] B22. Determine a second sending opportunity among the first sending opportunities as a time domain position of the target second signal, where the second sending opportunity is an available time unit with the shortest interval from the first signal sending time or the CSI reporting time among the first sending opportunities;

[0300] In some embodiments, X is a protocol agreement (or predefined) or a network device indication.
[0301] It should be noted that in this case, there will be multiple sending opportunities determined by each of the above-mentioned B231 and B232. When the terminal is actually used, it will try to send the target second signal at each sending opportunity based on the order of the sending opportunities. As long as the target second signal is successfully sent at a certain sending opportunity, the target second signal will no longer be sent at other subsequent sending opportunities.
[0302] In some embodiments, when the third sending opportunity includes B231, Y available time units before or after the sending 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 sending opportunity includes B232, X available time units before or after the moment of reporting the CSI 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 sending opportunity includes B231 and B232, Y available time units before or after the sending moment of the first signal associated with the target second signal and X available time units before or after the moment of reporting the CSI corresponding to the first signal associated with the target second signal are determined as the time domain position of the target second signal.
[0303] B12. Determine the transmission parameter of the first signal associated with the target second signal as the transmission parameter of the target second signal.
[0304] 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 can be the first signal corresponding to the CSI reporting configuration information indicated in the association relationship.
[0305] In some embodiments, in one implementation, determining the transmission parameter of the first signal associated with the target second signal as the transmission parameter of the target second signal includes at least one of the following:
[0306] B121. Determine the TCI state of the first signal associated with the target second signal as the TCI state of the target second signal;
[0307] 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.
[0308] B122. Determine the QCL parameters of the first signal associated with the target second signal as the QCL parameters of the target second signal;
[0309] It should be noted that by setting the QCL parameters of the target second signal to be the same as the QCL parameters of the associated first signal, the target second signal can be made QCL with the associated first signal.
[0310] B123. Determine the port that receives the first signal associated with the target second signal as the port that sends the target second signal;
[0311] This situation can be understood as using the receiving port of the first signal associated with the target second signal as the sending port of the target second signal.
[0312] B124. Determine the frequency of receiving the first signal associated with the target second signal as the frequency of sending the target second signal;
[0313] This situation can be understood as using the receiving frequency of the first signal associated with the target second signal as the sending frequency of the target second signal.
[0314] B125. Determine the spatial filter that receives the first signal associated with the target second signal as the spatial filter that sends the target second signal;
[0315] This situation can be understood as using the receiving spatial filter of the first signal associated with the target second signal as the sending spatial filter of the target second signal.
[0316] It should be noted that, from the above description, the transmission parameters determined in the embodiment of the present disclosure need to include at least one of: TCI state, QCL parameters, port, frequency and spatial filter; which transmission parameters the terminal needs to use can be determined based on the corresponding methods in the above B121-B125.
[0317] It should be noted that by sending the target second signal based on at least one of the above B121-B125, the target second signal and the first signal can be QCL, so that the sending time of the target second signal meets the processing requirements of the network side, and ensures that the two correspond to the same transceiver antenna or antenna port.
[0318] The following uses the case where the first signal corresponds to a CSI-RS resource, the second signal corresponds to an SRS resource, and the base station communicates with the terminal as an example to illustrate the specific application of the embodiment of the present disclosure.
[0319] Application scenario 1: The terminal receives signaling from the base station that configures the association relationship between CSI-RS resources and SRS resources. The signaling also indicates the time slot offset of the SRS resources. The terminal determines the target SRS and the corresponding parameter information.
[0320] In this case, the above-mentioned target information corresponds to at least one CSI-RS resource, and the association relationship between the target information and at least one second signal corresponds to the association relationship between at least one CSI-RS resource and at least one SRS resource, which can be simply referred to as the association relationship between CSI-RS resources and SRS resources in this application scenario; the time slot offset of the second signal corresponds to the time slot offset of the SRS resource.
[0321] It should be noted that CSI-RS resources are classified as periodic, semi-persistent, and aperiodic. SRS resources are classified as periodic, semi-persistent, and aperiodic. In this application scenario, when the base station indicates the association between CSI-RS and SRS resources via signaling, the CSI-RS resource must be at least one of the following: periodic, semi-persistent, or aperiodic; and the SRS resource must be at least one of the following: periodic, semi-persistent, or aperiodic.
[0322] The terminal obtains the association relationship between the CSI-RS resources and the SRS resources indicated by the base station in at least one of the following ways:
[0323] Method 1:
[0324] The terminal receives RRC signaling sent by the base station for configuring the CSI trigger state and aperiodic CSI-RS resources, and determines the association between CSI-RS resources and SRS resources. This association can also be expressed as an association between a CSI-RS resource set and an SRS resource set. A CSI-RS resource set includes one or more CSI-RS resources, and an SRS resource set includes one or more SRS resources. When configuring aperiodic CSI-RS, this RRC signaling also indicates the SRS resources associated with each aperiodic CSI-RS resource.
[0325] For example, the associated SRS resource set identifier (associatedSRS-ResourceSetId) and slot offset (slotOffset) are added to CSI-AperiodicTriggerStateList or CSI-ResourceConfig to indicate the associated SRS resource set ID and the slot offset of the SRS resource. The slot offset can also be named not slotOffset, which is the same as the parameter name in the SRSConfig signaling, but slotOffset-r19, etc. to distinguish it.
[0326] For example, one way to add an association relationship in CSI-AperiodicTriggerStateList is as follows:
[0327] The range of associatedSRS-ResourceSetId includes all SRS resource set IDs allocated to the terminal, and the range of slotOffset is 0 to the upper limit k that meets the base station channel calculation requirement, where k is a positive integer.
[0328] The base station can use explicit or implicit methods to indicate whether the association relationship is effective. For example, the terminal determines that the association relationship is effective only when the CSI-AperiodicTriggerStateList or CSI-ResourceConfig contains associatedSRS-ResourceSetId and slotOffset. The terminal can also determine whether the association relationship is effective (or whether to activate the association relationship) through a parameter configured by the base station in RRC signaling, MAC CE or DCI. For example, an unused 1-bit parameter is added or reused. When the parameter value is 1, the terminal determines that the association relationship is effective. When the parameter value is 0, the terminal determines that the association relationship is not effective.
[0329] Method 2:
[0330] In RRC signaling, the base station configures not only the SRS resource set and slot offset associated with the aperiodic CSI-RS resource configuration, but also the SRS resource set and slot offset associated with the semi-persistent CSI-RS resource configuration and periodic CSI-RS resource configuration. Upon receiving this RRC signaling, the terminal determines the association between the CSI-RS and SRS resources based on the signaling content (i.e., the identification information of the SRS resources associated with the CSI-RS resources carried in the RRC signaling).
[0331] For example, the associated SRS resource set (associatedSRS-ResourceSetId) and the time slot offset (slotOffset) are added to the CSI-ResourceConfig to indicate the associated SRS resource set ID and the time slot offset of the SRS resource.
[0332] For example, one way to add an association in CSI-ResourceConfig is as follows:
[0333] The range of associatedSRS-ResourceSetId includes all SRS resource set IDs allocated to the terminal, and the range of slotOffset is 0 to the upper limit k that meets the base station channel calculation requirement, where k is a positive integer.
[0334] The base station can use explicit or implicit methods to indicate whether the association is valid. For example, the terminal only determines that the association is valid when the CSI-ResourceConfig contains associatedSRS-ResourceSetId and slotOffset. The terminal can also determine whether the association is valid (or whether to activate the association) through a parameter configured by the base station in RRC signaling, MAC CE signaling, or DCI signaling.
[0335] Method 3:
[0336] The association relationship between semi-persistent CSI-RS resources and SRS resources is not indicated through RRC signaling. The terminal receives a MAC-CE for activating CSI reporting or activating CSI-RS transmission, and determines the association relationship between CSI-RS resources and SRS resources based on the signaling content (i.e., the identification information of the SRS resources associated with the CSI-RS resources carried in the MAC-CE).
[0337] For example, in the Aperiodic CSI Trigger State Subselection MAC CE signaling, an SRS resource set ID is configured for each of the activated trigger states, or for some of the activated trigger states. The terminal can use a 1-bit indication configured by the network in the MAC CE signaling to determine whether the association is valid, or it can make an implicit determination by indicating that the association is valid only when an SRS resource set ID is configured for the trigger state.
[0338] For example, a method of adding an association relationship in the Aperiodic CSI Trigger State Subselection MAC CE signaling is shown in FIG3 . i Indicates different non-periodic CSI trigger states. When selecting all or part of the trigger states to be activated, the corresponding T i The associated SRS resource set ID and time slot offset are added.
[0339] Method 4:
[0340] The association relationship between CSI-RS resources and SRS resources is not indicated through RRC signaling and MAC CE. The UE receives DCI signaling that triggers non-periodic CSI reporting or semi-continuous CSI reporting, and determines the association relationship between CSI-RS resources and SRS resources based on 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 to the 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) based on an additional indication information configured by the base station (such as an RRC parameter). If the association relationship is effective, the terminal determines that the CSI-RS resource indicated by the CSI request field in this DCI is associated with the SRS resource set indicated by the SRS request field.
[0341] For example, in the DCI signaling that triggers aperiodic CSI reporting or semi-persistent CSI reporting, a new 1-bit field is added. The bit value in this field is 0, indicating 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. The bit value in the new field is 1, indicating 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.
[0342] 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 resource and the corresponding parameter information.
[0343] The terminal determines the transmission parameters of the target SRS resource in the following manner:
[0344] When transmitting a target SRS resource, the terminal uses the receive port of the CSI-RS resource associated with the target SRS resource as the transmit port. When transmitting a target SRS resource, the terminal uses the receive frequency of the CSI-RS resource associated with the target SRS resource as the transmit frequency of the target SRS resource. When transmitting a target SRS resource, the terminal 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 transmitting a target SRS resource, the terminal uses the receive spatial filter of the CSI-RS resource associated with the target SRS resource as the transmit spatial filter of the target SRS resource, ensuring that both are in QCL.
[0345] It should be noted that when the receive spatial filters of the CSI-RS resources of multiple TRPs are different, the terminal can use a different transmit spatial filter for each SRS resource in the associated SRS resource set, and each transmit spatial filter corresponds to a receive spatial filter of the CSI-RS resource associated with the SRS resource. In this way, the CSI-RS resource transmitted by each TRP is QCLed with the SRS resource received by the TRP.
[0346] For example, the terminal is configured with 4 SRS resource sets, which are associated with the CSI-RS resource sets of 4 TRPs respectively. The terminal uses the receive spatial filter of the CSI-RS resource set of each TRP as the transmit spatial filter of the associated SRS resource set. For another example, the terminal is configured with an SRS resource set, which has 4 SRS resources, which are associated with the CSI-RS resource sets of 4 TRPs respectively. The terminal uses the receive spatial filter of the CSI-RS resource set of each TRP as the transmit spatial filter of the associated SRS resource.
[0347] The terminal determines the time domain location of the transmission target SRS resource in the following manner:
[0348] The time domain position of the target SRS resource is determined according to the time starting point and the time slot offset of the target SRS resource.
[0349] It can be understood that the terminal transmits the SRS 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.
[0350] The starting point for calculating the time slot offset of the SRS resource (that is, the time starting point of the target SRS resource) can be at least one of the following: the sending time of the associated CSI-RS resource, the CSI reporting time corresponding to the associated CSI-RS resource, and the receiving time of the signaling for activating the association relationship.
[0351] It should be noted that the reason the starting point for calculating the SRS resource slot offset is at least one of the above is that, in the current protocol, there is no correlation between SRS transmission and CSI-RS transmission or CSI reporting times. To ensure that the CSI-RS transmission or CSI reporting times and the SRS transmission times used to estimate uplink channel information meet network-side processing requirements, the SRS transmission time needs to be correlated with its associated CSI-RS transmission or CSI reporting times. Therefore, the above starting point for calculating the SRS resource slot offset is selected.
[0352] Specifically, the specific timing of SRS transmission in this application case is:
[0353] 1. The terminal receives signaling from the base station that configures the association relationship between CSI-RS resources and SRS resources. The terminal establishes the association relationship between CSI-RS resources and SRS resources according to the signaling and obtains the SRS time slot offset.
[0354] 2. The terminal determines the starting point for calculating the time slot offset of the SRS resource according to the signaling for configuring the association 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.
[0355] 3. At a time that is a time slot offset from the starting point by the SRS resource indicated by the base station, the terminal sends the SRS to be sent determined according to the association relationship between the CSI-RS resource and the SRS resource.
[0356] Application scenario 2: The terminal receives the signaling from the base station that configures the CSI reporting configuration information and the SRS resource association relationship. The signaling also indicates the time slot offset of the SRS resource. The terminal determines the target SRS and the corresponding parameter information.
[0357] In this case, the above-mentioned target information corresponds to at least one CSI reporting configuration information, and the association relationship between the target information and at least one second signal corresponds 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 CSI reporting configuration information and SRS resources; the time slot offset of the second signal corresponds to the time slot offset of the SRS resource.
[0358] The terminal obtains the association relationship between the CSI-RS resources and the SRS resources indicated by the base station in at least one of the following ways:
[0359] Method 1:
[0360] The terminal receives RRC signaling sent by the base station for CSI reporting configuration information and aperiodic CSI-RS resource configuration, and determines the association between the CSI reporting configuration information and the SRS resources. This association can also be expressed as an association between the CSI-RS reporting configuration information and an SRS resource set, where 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.
[0361] For example, an associated SRS resource set (associated SRS resource set) and a slot offset (slotOffset) are added to CSI-AperiodicTriggerStateList or CSI-ReportConfig.
[0362] For example, one way to add an association in CSI-ReportConfig is as follows:
[0363] The range of associatedSRS-ResourceSetId includes all SRS resource set IDs allocated to the terminal, and the range of slotOffset is 0 to the upper limit k that meets the base station channel calculation requirement, where k is a positive integer.
[0364] The base station uses explicit or implicit methods to indicate whether the association relationship is effective. For example, the terminal determines that the association relationship is effective only when the CSI-AperiodicTriggerStateList or CSI-ReportConfig contains associatedSRS-ResourceSetId and slotOffset. The terminal can also determine whether the association relationship is effective (or whether to activate the association relationship) through a parameter configured by the base station in RRC signaling, MAC CE or DCI. For example, an unused 1-bit parameter is added or reused. When the parameter value is 1, the terminal determines that the association relationship is effective. When the parameter value is 0, the terminal determines that the association relationship is not effective.
[0365] Method 2:
[0366] The base station does not indicate the association between the CSI reporting configuration information and the SRS resources through RRC signaling. The terminal receives the MAC-CE that activates CSI reporting and determines the association between the CSI reporting configuration information and the SRS resources based on 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).
[0367] For example, in the SP CSI reporting on PUCCH Activation / Deactivation MAC CE signaling, an SRS resource set ID is configured for each of the activated CSI reporting configuration information, or for all or part of the activated CSI reporting configuration information. The base station may use a 1-bit in the MAC CE signaling to indicate whether the association relationship is valid, or may implicitly indicate whether the association relationship is valid only when an SRS resource set ID is configured for whether the CSI association relationship is valid.
[0368] For example, a method of adding an association relationship in SP CSI reporting on PUCCH Activation / Deactivation MAC CE signaling is shown in FIG4 . i Indicates different semi-persistent CSI reporting configuration activation states. When selecting the S corresponding to the activated full or partial trigger state i The associated SRS resource set (associated SRS resource set) and slot offset (slotOffset) are added.
[0369] Method 3:
[0370] The base station does not indicate the association between the CSI-RS reporting configuration information and the SRS resources through RRC signaling and MAC CE. The terminal receives DCI signaling that triggers aperiodic CSI reporting or semi-continuous CSI reporting, and determines the association between the CSI reporting configuration information and the SRS resources based on 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 to the DCI to indicate whether the association is effective (whether the association is activated). The terminal can also determine whether the association is effective (whether the association is activated) based on an additional indication information configured by the base station (such as an RRC parameter). If the association 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.
[0371] After receiving the association relationship between the CSI-RS reporting configuration information and the SRS resource sent by the base station, the terminal needs to determine the target SRS resource and the corresponding parameter information.
[0372] The terminal determines the transmission parameters of the target SRS resource in the following manner:
[0373] When the terminal sends the target SRS resource, the receiving port of the CSI-RS resource corresponding to the CSI-RS reporting configuration information associated with the target SRS resource is used as the transmitting port. When the terminal sends the target SRS resource, the receiving frequency of the CSI-RS resource corresponding to the CSI-RS reporting configuration information associated with the target SRS resource is used as the transmitting frequency of the target SRS resource. When the terminal sends the target SRS resource, the TCI state of the CSI-RS resource corresponding to the CSI-RS reporting configuration information associated with the target SRS resource is used as the TCI state of the target SRS resource. When the terminal sends the target SRS resource, the receiving spatial filter of the CSI-RS resource corresponding to the CSI-RS reporting configuration information associated with the target SRS resource is used as the transmitting spatial filter of the target SRS resource, so that the two are QCL.
[0374] It should be noted that when the receive spatial filters of the CSI-RS resources of multiple TRPs are different, the terminal can use a different transmit spatial filter for each SRS resource in the associated SRS resource set, and each transmit spatial filter corresponds to a receive spatial filter of the CSI-RS resource associated with the SRS resource. In this way, the CSI-RS resource sent by each TRP is QCL with the SRS resource received by the TRP.
[0375] For example, the terminal is configured with 4 SRS resource sets, which are associated with the CSI reporting settings of 4 TRPs respectively. The terminal uses the receiving spatial filter of the CSI-RS resource corresponding to the CSI reporting setting of each TRP as the transmitting spatial filter of the associated SRS resource set. For another example, the terminal is configured with an SRS resource set, which has 4 SRS resources, which are associated with the CSI reporting settings of 4 TRPs respectively. The terminal uses the receiving spatial filter of the CSI-RS resource corresponding to the CSI reporting setting of each TRP as the transmitting spatial filter of the associated SRS resource.
[0376] The terminal determines the time domain location of the transmission target SRS resource in the following manner:
[0377] The time domain position of the target SRS resource is determined according to the time starting point and the time slot offset of the target SRS resource.
[0378] It can be understood that the terminal transmits the SRS 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.
[0379] The starting point of the SRS resource time slot offset calculation (that is, the time starting point of the target SRS resource) can be at least one of the following: the reporting time corresponding to the associated CSI reporting configuration information, the CSI-RS sending time corresponding to the associated CSI reporting configuration information, and the signaling reception time for activating the association relationship.
[0380] Specifically, the specific timing of SRS transmission in this application case is:
[0381] 1. The terminal receives signaling from the network side that configures the association relationship between CSI reporting configuration information and SRS resources. The UE establishes the association relationship between the CSI reporting configuration information and SRS resources according to the signaling and obtains the time slot offset of the SRS resources.
[0382] 2. The terminal determines the starting point for calculating the time slot offset of the SRS resource according to the signaling of the association relationship between the CSI reporting configuration information and the SRS resource or according to other signaling of the base station. When the starting point for calculating the time slot offset of the SRS resource is reached, the terminal starts timing.
[0383] 3. At a time that is a time slot offset from the starting point by the SRS resource indicated by the base station, the terminal sends the SRS to be sent determined according to the association relationship between the CSI reporting configuration information and the SRS resource.
[0384] Application scenario 3: The terminal receives a signal from the base station that configures the association between CSI-RS resources and SRS resources. The signal does not indicate the time slot offset of the SRS resources. The terminal determines the target SRS and the corresponding parameter information.
[0385] In this case, the above-mentioned target information corresponds to at least one CSI-RS resource, and the association relationship between the target information and at least one second signal corresponds 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 CSI-RS resources and SRS resources.
[0386] The method for the terminal to determine the association between the CSI-RS resources and SRS resources indicated by the base station according to the signaling can be found in Application 1 and will not be repeated here; however, in this case, the base station no longer indicates the time slot offset of the SRS resources.
[0387] The manner in which the terminal determines the transmission parameters of the target SRS resource can be found in the first application scenario and will not be described in detail here.
[0388] The terminal determines the CSI-RS resource transmission time indicated by the base station in the establishment of the association relationship between the CSI-RS resource and the SRS resource, and the reporting time corresponding to the CSI measured by the CSI-RS resource, based on the signaling. On this basis, the terminal can determine the time domain location for transmitting the SRS resource and send the SRS according to at least one of the following methods, and the corresponding base station monitors at the corresponding time domain location:
[0389] E11. If the terminal receives DCI signaling that triggers aperiodic or semi-persistent CSI reporting, it sends the SRS using the target SRS resource in the next available time unit;
[0390] E12. The terminal transmits the SRS using 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 slot;
[0391] E13. The terminal sends an SRS using 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 slot / symbol;
[0392] E14. The terminal calculates all available time units for the three cases in E11-E13 above, and uses the available time unit closest to the CSI-RS transmission time or the CSI reporting time to send the SRS through the target SRS resource;
[0393] E15. The terminal attempts to send an SRS through the target SRS resource within Y available time units after or before the CSI-RS transmission time slot / symbol, and does not send the SRS again after successful transmission;
[0394] E16. The terminal attempts to send an SRS through the target SRS resource within X available time units before or after the CSI reporting time slot / symbol, and does not send the SRS again after successful transmission.
[0395] Specifically, the specific timing of SRS transmission in this application case is:
[0396] 1. The terminal receives a signaling from the base station that configures an association relationship between CSI-RS resources and SRS resources, and the terminal establishes an association relationship between the CSI-RS resources and SRS resources according to the signaling.
[0397] 2. The terminal determines, based on the signaling for configuring the association between the CSI-RS resource and the SRS resource or other signaling from the base station, the sending time of the CSI-RS resource in establishing the association between the CSI-RS resource and the SRS resource, and the reporting time corresponding to the CSI measured by the CSI-RS resource.
[0398] 3. According to different ways in which the terminal determines the time domain location of the SRS resource to be transmitted, there are the following possible timing relationships:
[0399] Case 1: If the terminal receives DCI signaling that triggers aperiodic or semi-persistent CSI reporting, it sends SRS in the next available time unit;
[0400] The timing relationship at this time is: the terminal first receives the DCI signaling that triggers aperiodic or semi-persistent CSI reporting, and the terminal calculates the next available time unit and sends the SRS in the time unit.
[0401] Case 2: The terminal transmits the SRS in the mth available time unit after or before the CSI-RS transmission time slot / symbol according to the obtained CSI-RS transmission time slot;
[0402] If the associated SRS is transmitted in the mth available time unit before the obtained CSI-RS transmission time slot / symbol, the timing relationship is as follows: the terminal first receives the signaling from the base station instructing CSI-RS transmission and obtains the CSI-RS transmission time based on the signaling. The terminal then transmits the SRS in the mth available time unit before the obtained CSI-RS transmission time slot / symbol. The terminal then receives the CSI-RS transmitted by the base station.
[0403] If the SRS is transmitted in the mth available time unit after the obtained CSI-RS transmission time slot / symbol, the timing relationship is as follows: the terminal first receives the signaling from the base station instructing CSI-RS transmission and obtains the CSI-RS transmission time based on the signaling. The terminal then receives the CSI-RS transmitted by the base station. The terminal then transmits the associated SRS in the mth available time unit after the obtained CSI-RS transmission time slot / symbol.
[0404] Case 3: The terminal sends the SRS in the nth available time unit after or before the CSI reporting time slot / symbol according to the CSI reporting time;
[0405] If the associated SRS is transmitted in the mth available time unit before the obtained CSI reporting time slot / symbol, the timing relationship is as follows: the terminal first receives the signaling from the base station instructing CSI reporting and obtains the CSI reporting time based on the signaling. Then, the terminal transmits the associated SRS in the mth available time unit before the obtained CSI reporting time slot / symbol. The terminal then reports CSI.
[0406] If the associated SRS is transmitted in the mth available time unit after the obtained CSI reporting time slot / symbol, the timing relationship is as follows: the terminal first receives the signaling from the base station instructing CSI reporting and obtains the CSI reporting time based on the signaling. Then, the terminal reports the CSI. Then, the terminal transmits the associated SRS in the mth available time unit after the CSI reporting time slot / symbol.
[0407] Case 4: The terminal calculates all available time units for the above three cases and selects the available time unit closest to the CSI-RS transmission time or CSI reporting time to send the SRS;
[0408] If the selected SRS transmission timing is closest to the CSI-RS transmission time and precedes the CSI-RS transmission time, the timing relationship is as follows: the terminal first receives the signaling from the base station indicating CSI-RS transmission and obtains the CSI-RS transmission time based on the signaling. The terminal then transmits the associated SRS in the first available time unit before the obtained CSI-RS transmission time slot / symbol. The terminal then receives the CSI-RS transmitted by the base station.
[0409] If the selected SRS transmission timing is closest to the CSI-RS transmission time and occurs after the CSI-RS transmission time, the timing relationship is as follows: the terminal first receives the signaling from the base station instructing CSI-RS transmission and obtains the CSI-RS transmission time based on the signaling. The terminal then receives the CSI-RS transmitted by the base station. The terminal then transmits the SRS in the first available time unit after the obtained CSI-RS transmission time slot / symbol.
[0410] If the selected SRS transmission timing is closest to the CSI reporting time and precedes the CSI reporting time, the timing relationship is as follows: the terminal first receives the base station's signaling instructing CSI reporting and obtains the CSI reporting time based on the signaling. The terminal then transmits the SRS in the first available time unit before the obtained CSI reporting time slot / symbol. The terminal then reports the CSI.
[0411] If the selected SRS transmission timing is closest to the CSI reporting time and occurs after the CSI reporting time, the timing relationship is as follows: the terminal first receives the base station's signaling instructing CSI reporting and obtains the CSI reporting time based on the signaling. The terminal then reports the CSI. The terminal then transmits the SRS in the first available time unit after the CSI reporting time slot / symbol.
[0412] Case 5: The terminal attempts to send SRS within m available time units after or before the CSI-RS transmission time slot / symbol, and does not send again after successful transmission;
[0413] If you choose to attempt to transmit the SRS within m available time units before the obtained CSI-RS transmission time slot / symbol, and then stop transmitting after a successful transmission, the timing relationship in this case is as follows: the terminal first receives the signaling from the base station instructing CSI-RS transmission and obtains the CSI-RS transmission time based on the signaling. The terminal then attempts to transmit the 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 have been exhausted. The terminal then receives the CSI-RS sent by the network.
[0414] If you choose to attempt to transmit the SRS within m available time units after the obtained CSI-RS transmission slot / symbol, and then stop transmitting after a successful transmission, the timing relationship in this case is as follows: the terminal first receives the signaling from the base station instructing CSI-RS transmission and obtains the CSI-RS transmission time based on the signaling. Then, the terminal receives the CSI-RS transmitted by the base station. Then, the terminal attempts to transmit the associated SRS within m available time units after the obtained CSI-RS transmission slot / symbol, until transmission is successful or all available time units have been exhausted.
[0415] Case 6: The terminal sends SRS within n available time units after or before the CSI reporting time slot / symbol, and does not send again after successful transmission.
[0416] If you choose to attempt to transmit the associated SRS within m available time units before the obtained CSI reporting time slot / symbol, and then stop transmitting after a successful transmission, the timing relationship in this case is as follows: the terminal first receives the signaling from the base station instructing CSI reporting and obtains the CSI reporting time based on the signaling. The terminal then 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 have been exhausted. The terminal then reports CSI.
[0417] If you choose to attempt to transmit the SRS within m available time units after the obtained CSI reporting time slot / symbol, and then stop transmitting after a successful transmission, the timing relationship in this case is as follows: the terminal first receives the signaling from the base station instructing CSI reporting and obtains the CSI report based on the signaling. The terminal then reports the CSI. Then, the terminal attempts to transmit the SRS within m available time units after the CSI reporting time slot / symbol until the transmission is successful or all available time units have been exhausted.
[0418] Application scenario 4: The terminal receives a signaling from the base station that configures the association between CSI reporting configuration information and SRS resources. The signaling does not indicate the time slot offset of the SRS resources. The terminal determines the target SRS and the corresponding parameter information.
[0419] In this case, the above-mentioned target information corresponds to at least one CSI reporting configuration information, and the association relationship between the target information and at least one second signal corresponds 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 CSI reporting configuration information and SRS resources.
[0420] The method for the terminal to determine the association relationship between the base station's CSI-RS reporting configuration information and the SRS resource according to the signaling can be found in Application Scenario 2 and will not be repeated here. However, in this case, the base station no longer indicates the time slot offset of the SRS resource.
[0421] The manner in which the terminal determines the transmission parameters of the target SRS resource can be found in the second application scenario and will not be described in detail here.
[0422] The terminal determines the CSI reporting time in the association relationship between CSI reporting configuration information and SRS resources indicated by the network side based on the signaling, as well as the CSI-RS resource transmission time corresponding to the CSI reporting configuration information. On this basis, the terminal can determine the time domain location for transmitting SRS resources and transmit SRS according to at least one of the following methods, and the corresponding base station monitors at the corresponding time domain location:
[0423] E21. If the terminal receives DCI signaling that triggers aperiodic or semi-persistent CSI reporting, it sends the SRS using the target SRS resource in the next available time unit;
[0424] E22. The terminal transmits an SRS using 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 slot;
[0425] E23. The terminal sends an SRS using 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;
[0426] E24. The terminal calculates all available time units for the three cases in E21-E23 above, and selects the available time unit closest to the CSI-RS transmission time or the CSI reporting time to send the SRS using the target SRS resource;
[0427] E25. The terminal attempts to send an SRS through the target SRS resource within Y available time units after or before the CSI-RS transmission time slot / symbol, and does not send the SRS again after successful transmission;
[0428] E26. The terminal attempts to send an SRS through the target SRS resource within X available time units before or after the CSI reporting time slot / symbol, and does not send the SRS again after successful transmission.
[0429] It should be noted here that the main difference between application scenario 4 and application scenario 3 is that application scenario 4 establishes an association relationship between CSI reporting configuration information and SRS resources, while application scenario 3 establishes an association relationship between CSI-RS resources and SRS resources.
[0430] Specifically, the specific timing of SRS transmission in this application case is:
[0431] 1. The terminal receives signaling from the base station that configures the association relationship between CSI reporting configuration information and SRS resources, and the terminal establishes the association relationship between the CSI reporting configuration information and the SRS resources according to the signaling.
[0432] 2. The terminal determines, according to the signaling for configuring the association between the CSI reporting configuration information and the SRS resources or other signaling from the base station, the CSI reporting time for establishing the association between the CSI reporting configuration information and the SRS resources, and the sending time corresponding to the CSI-RS corresponding to the CSI reporting setting.
[0433] 3. Different ways of determining the time domain position of the SRS resource to be transmitted according to the terminal can be referred to the specific timing relationship of application scenario 3, which will not be described in detail here.
[0434] It should be noted that, preferably, the embodiments of the present disclosure propose a triggering method for SRS based on the association between CSI-RS resources or CSI reporting configuration information and SRS resources. According to the embodiments of the present disclosure, the terminal can, based on the configuration of the network side, make the time of CSI-RS sending or CSI reporting and the SRS sending time for estimating uplink channel information meet the processing requirements of the network side, and ensure that the two correspond to the same transmission parameters, and then ensure that the two correspond to the same TCI state or QCL parameters; thereby ensuring the accuracy of the calibration coefficient calculated by the network side.
