[0038] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0039] The base station configures a measurement configuration (MeasConfig) for a terminal through RRC signaling. Each cell group corresponds to a Measconfig, and the cell group includes a master cell group (MCG) and a secondary cell group (SCG). The MeasConfig includes one or more measurements (Meas), and one Meas includes the following information: the measurement index (MeasId) of the Meas, a measurement target (MeasObject) and a reporting configuration (Reportconfig), that is, a Meas establishes an association between the MeasObject and the Reportconfig, and configures the triggering conditions for reporting inter-cell measurement information in the reportConfig. The configuration elements configured in each MeasObject are shown in Table 1.

[0040] Table 1

[0041]

[0042] The aforementioned physical-layer cell identity (PCI) range element (PCI-RangeElement) is configured with starting PCI information and PCI length. That is, a PCI-RangeElement includes one PCI or multiple consecutive PCIs. The aforementioned synchronization signal and physical broadcast channel (SSB) information includes information about the SSBs corresponding to all PCIs in the MeasObject. A frequency domain (such as an SSB frequency (ssbFrequency) in Table 1) corresponds to many PCIs. In the existing New Radio (NR) protocol, a frequency domain corresponds to a maximum of 1008 PCIs. A PCI corresponds to multiple SSBs in the time domain. Different SSBs in the time domain are represented by SSB indices (ssb-Index). For example, a PCI corresponds to 64 SSBs in the time domain. SSBs with different time domain indices represent different quasi-co-located reference signal resources. Different SSB indices can be simply considered to correspond to different transmit beams of the base station. The SSB sequences sent in the 64 time-domain SSBs corresponding to a PCI are the same. The SSB sequence includes the primary synchronization signal (PSS) and the second synchronization signal (SSS) included in the SSS, also known as the secondary synchronization signal (SSS). A (PSS, SSS) combination corresponds to a PCI, and the sequence generation parameters of PSS and SSS in the (PSS, SSS) combination include the PCI information. For example, the 64 time-domain SSBs corresponding to PCI1 are sent periodically. For example, the time domain resource span occupied by the 64 SSBs is 5ms, and the period is 20ms. Then, there is an SSB in one of every four 5ms. PCI 2 and PCI 1 in a MeasObject correspond to 64 time-domain SSBs respectively. The time domain resources occupied by the SSBs corresponding to the two PCIs are the same, but the SSB sequence information is different, that is, different PCIs on the same frequency domain ssbFrequency are code-divided. Of course, if the SSBs corresponding to different PCIs are sent by different nodes to the same UE, and the transmission delays between different nodes and the terminal are quite different (for example, exceeding the cyclic prefix (CP) range), even if the transmission time of the two nodes is synchronized, different PCIs cannot share the downlink timing. The terminal obtains the downlink timing corresponding to different PCIs based on the SSBs corresponding to each PCI, such as Figure 2 As shown, at this time, the SSBs corresponding to different PCIs can be considered to be both code-divided and time-divided.

[0043] The reference signal configuration (ReferenceSignalConfig) configuration element in Table 1 is used to configure the measurement reference signal included in the MeasObject. For simplicity, this measurement reference signal is hereinafter referred to as the Mobility Measurement Reference Signal (also known as the Mobility Measurement Reference Signal). Specifically, the ReferenceSignalConfig element includes the configuration elements shown in Table 2.

[0044] Table 2

[0045]

[0046] The SSB mobility configuration (SSB-ConfigMobility) in Table 2 configures the time domain selection information of the SSB. For example, when the maximum number of time domains of the SSB is 64, the base station configures the terminal with which SSBs among the 64 SSBs the terminal needs to measure. For example, it uses 64 bits to represent that the terminal only needs to detect 4 of the 64 time domain SSBs. All PCIs included in the MeasObject in Table 2 share one SSB-ConfigMobility configuration element. The CSI-RS mobility resource configuration (CSI-RS-ResourceConfigMobility) configuration element in Table 2 is used to configure the CSI-RS information included in the MeasObject. The CSI-RS-ResourceConfigMobility configuration element includes the configuration elements shown in Table 3.

[0047] Table 3

[0048]

[0049]

[0050] The CSI-RS-CellMobility configuration element in Table 3 includes the configuration elements shown in Table 4.

[0051] Table 4

[0052]

[0053] As can be seen from Tables 3 and 4, CSI-RS-ResourceConfigMobility will configure the Channel State Information Reference Signal (CSI-RS) information corresponding to multiple PCIs, but the subcarrier spacing of the CSI-RS corresponding to these multiple PCIs is the same, and each CSI-RS mobility cell (CSI-RS-CellMobility) corresponds to one PCI (i.e., PhysCellId). In the CSI-RS-Resource-Mobility configuration element in Table 4, the time domain symbol information, time slot information, period information, resource element (RE) information, and code domain information occupied by each Mobility CSI-RS resource are configured, as shown in Table 5.

[0055]

[0056] Figure 1 A flowchart of a method for receiving control signaling provided in an embodiment is shown in FIG. Figure 1 As shown, the method provided in this embodiment includes the following steps.

[0057] Step S1010: Receive first control signaling, where the first control signaling includes first-type parameters corresponding to a sounding reference signal, wherein the first-type parameters include a physical cell identifier or a physical cell identifier and second-type parameters.

[0058] The control signaling receiving method provided in this embodiment is executed by a first communication node in a wireless communication network, wherein the first communication node is a node that receives the control signaling of the second communication node to complete various services in the wireless communication network, and the first communication node is, for example, a terminal, and the second communication node is, for example, a base station. In a traditional wireless communication network, the terminal reports the cell measurement result in the RRC signaling, but the RRC signaling is a high-layer signaling with a high transmission delay, which affects the cell switching speed. The reference signal resource used by the terminal for cell measurement is determined based on the service cell identifier in the channel state information (CSI) reporting configuration (CSI-ReportConfig) issued by the base station. According to the service cell identifier, only the measurement reference signal of the service cell can be uniquely determined in the CSI reporting configuration information. Therefore, according to the CSI reporting configuration issued by the base station, only the measurement of the service cell can be completed, and the measurement result can be reported through RRC signaling.

[0059] In this embodiment, the first communication node, i.e., the terminal, receives first control signaling that includes first-type parameters corresponding to a measurement reference signal. The first communication node then determines the measurement reference signal based on the first-type parameters. The measurement reference signal determined based on the first-type parameters can be not only the measurement reference signal of the serving cell, but also other measurement reference signals corresponding to the first-type parameters. The first communication node can then perform mobility measurements based on the measurement reference signals of non-serving cells. The mobility measurement results can be sent to the second communication node, i.e., the base station, at the network layer via physical layer signaling, thereby reducing the reporting delay of the mobility measurement results.

[0060] The first type of parameters includes PCI or physical cell identifier and second type of parameters. That is, the identifier of the cell where mobility measurement is required and the related information of the required measurement can be determined based on the first type of parameters.

[0061] The measurement reference signal includes one of the following: a measurement reference signal in the CSI reporting configuration, a measurement reference signal whose measurement result is included in the uplink control information (UCI), a measurement reference signal in the measurement reference signal resource set configured in the serving cell, and a measurement reference signal in the beam failure candidate reference signal resource set.

[0062] In one embodiment, the measurement reference signal includes one of the following: a measurement reference signal in a measurement reference signal resource, a measurement reference signal in a measurement reference signal resource set, and a measurement reference signal in a measurement reference signal resource set list.

[0063] In one embodiment, the second type of parameters includes at least one of the following: a serving cell index (serving cellIndex), a measurement target index (MeasureobjectID), a measurement link index, a measurement configuration index (MeasconfigID), an absolute radio frequency channel number (NR Absolute Radio Frequency Channel Number, AFRCN), a parameter of a frequency domain reference point (PointA) for determining a frequency domain position occupied by a measurement reference signal, and a frequency domain bandwidth. In this embodiment, the frequency domain information includes one or more of PointA and the frequency domain bandwidth.

[0064] In one embodiment, a frequency domain bandwidth includes one of the following: a serving cell index, a component carrier (CC), a bandwidth part (BandWidth part, BWP), a physical resource block (PRB) set, a frequency band (Band), a PRB span, and a carrier frequency, wherein the PRB span includes a section of continuous PRBs, and the sounding reference signal occupies resources in every x PRBs in the PRB span, where x is a positive integer greater than or equal to 1.

[0065] In one embodiment, the second-category parameters are used to determine at least one of the following information about the measurement reference signal: the second-category parameters are used to determine a measurement target corresponding to the measurement reference signal; the second-category parameters are used to determine a reporting parameter corresponding to the measurement reference signal; and the second-category parameters are used to determine a measurement parameter corresponding to the measurement reference signal. In other words, at least one of the measurement target, reporting parameter, and measurement parameter corresponding to the measurement reference signal can be determined based on the second-category parameters.

[0066] In one embodiment, if the second type of parameters are used to determine the measurement target corresponding to the measurement reference signal, including at least one of the following: the measurement reference signal belongs to the mobility measurement reference signal configured in the measurement target corresponding to the measurement reference signal; the third type of parameters of the measurement reference signal are determined according to the measurement target corresponding to the measurement reference signal, wherein the third type of parameters include at least one of the following: the occupied PRB set, the subcarrier spacing, PointA, and the frequency domain bandwidth.

[0067] In one embodiment, if the second type of parameters is used to determine the measurement target corresponding to the measurement reference signal, and the measurement reference signal includes a synchronization signal, it also includes at least one of the following: the synchronization signal index belongs to the synchronization signal index set selected in the measurement target; the physical cell identifier included in the first type of parameters belongs to the white cell list, where the white cell is the white cell list in the measurement target; the physical cell identifier included in the first type of parameters does not belong to the black cell list, where the white cell is the black cell list in the measurement target, and the measurement target is the measurement target corresponding to the measurement reference signal.

[0068] In one embodiment, the reporting parameters include one of the following: reporting parameters of a triggering event, wherein a determination is made as to whether the triggering event is satisfied based on a measurement result obtained based on a measurement reference signal, and when satisfied, the measurement result is reported in the UCI; and reporting parameters configured in a measurement link index, wherein the measurement link index is determined based on the second type of parameters.

[0069] In one embodiment, the measurement target corresponding to the measurement reference signal includes one of the following: a measurement target corresponding to the serving cell in the second type of parameters, wherein the measurement target corresponding to the serving cell includes one of the following: a measurement target corresponding to the serving cell measurement target of the serving cell, a measurement target whose frequency domain information and the frequency domain information of the serving cell meet predetermined conditions; a measurement target corresponding to the measurement target index in the second type of parameters; a measurement target included in the measurement link corresponding to the measurement link index in the second type of parameters; and a measurement target corresponding to the measurement configuration index and the measurement target index in the second type of parameters.

[0070] Step S1020: Determine a measurement reference signal according to the first type of parameters to perform measurement and report the measurement result through the physical layer.

[0071] After receiving the first control signaling, the first communication node can determine the measurement reference signal to use for measurement. The first communication node can then perform inter-cell mobility measurements based on the determined measurement reference signal and report the measurement results through the physical layer, thereby reducing the reporting delay of the mobility measurement results and improving the cell switching speed.

[0072] In one embodiment, the first control signaling is taken as CSI-ReportConfig as an example. The measurement reference signal resources in the CSI-ReportConfig are determined according to the first type of parameters, that is, the PCI and frequency domain information are the PCI and frequency domain information corresponding to the measurement reference signal in the CSI-ReportConfig. Each (PCI, second type of parameters) combination corresponds to a measurement reference signal resource set list. Alternatively, the mobility measurement reference signal resources in the CSI-ReportConfig are determined by the first type of parameters, and the measurement reference signal of the non-mobility measurement reference signal resources in the CSI-ReportConfig is not determined by the first type of parameters. The measurement reference signal of the non-mobility measurement reference signal resources in the CSI-ReportConfig is determined according to the third information. At this time, the CSI-ReportConfig is configured for both the mobility measurement reference signal (PCI, second type of parameters) and the non-mobility measurement reference signal. The third information, for example, the third information is a serving cell index, indicating that the non-mobility measurement reference signal belongs to the measurement reference signal configured in the serving cell. The Mobility Measurement Reference Signal is included in one or more measurement targets (MeasObjects). Further, when the Mobility Measurement Reference Signal includes an SSB, the PCI corresponding to the SSB is included in the white cell list configured in the MeasObject, or the PCI corresponding to the SSB is not included in the black cell list configured in the MeasObject. Furthermore, the MeasObject to which the Mobility Measurement Reference Signal belongs includes one of the following: a measurement target MeasObject corresponding to a serving measurement (servingCellMO) configured in a serving cell, wherein the serving cell index is included in the second type of parameters; a MeasObject corresponding to a measurement target index (MeasureobjectID) in the second type of parameters; a MeasObject included in a MeaID in the second type of parameters; a MeasObject whose synchronization signal frequency domain information (ssbFrequency) is equal to (or the difference from the second type of parameters is less than a predetermined value) the AFRCN / PointA / frequency domain information in the second type of parameters.

[0073] When the second type of parameter is MeasureobjectID, if the measurement reference signal resource is SSB, the SSB frequency domain information is determined according to the ssbFrequency configured in the new radio measurement target index (MeasureobjectNR) corresponding to the MeasureobjectID. Furthermore, the time domain resource index corresponding to the SSB (also called the SSB index) belongs to the SSB index selected by the SSB measurement configuration (ssb-ToMeasure) configured in the MeasureobjectNR. If the measurement reference signal resource is CSI-RS, the PointA corresponding to the CSI-RS resource is configured according to the CSI-RS reference frequency (refFreqCSI-RS) in the MeasureobjectNR corresponding to the MeasureobjectID. Furthermore, the subcarrier spacing corresponding to the CSI-RS resource, the Band information can also be obtained through the subcarrier spacing configured in the CSI-RS mobility resource configuration (CSI-RS-ResourceConfigMobility) in the MeasureobjectNR corresponding to the MeasureobjectID. Or at this time, the measurement reference signal includes the measurement reference signal corresponding to the PCI configured in the MeasObject, including SSB or CSI-RS for Mobility measurement. Of course, this embodiment does not exclude the possibility that the measurement reference signal is not a mobility measurement reference signal, but the third type of parameters of the measurement reference signal resource are obtained through the information configured in the MeasureobjectNR corresponding to the MeasureobjectID, wherein the third type of parameters include at least one of the following information: occupied PRB span, subcarrier spacing, PointA, Band, and other information of the measurement reference signal is configured outside the MeasObject, wherein the other information of the measurement reference signal includes one or more of the following information: time domain parameters, occupied RE position, PRB position, number of ports, quasi-co-site measurement reference signal, etc., such as configured in the CSI resource configuration index (CSI-ResourceConfigId) associated with the CSI-ReportConfig, wherein the PRB span includes a continuous PRB, and the measurement reference signal occupies resources in every x PRBs in the PRB span, where x is a positive integer greater than or equal to 1.

[0074] When the second-category parameter is MeaID, the third-category parameter of the measurement reference signal resource is obtained based on the Measobject included in the MeasID, or the measurement reference signal resource belongs to the measurement reference signal configured in the Measobject included in the MeasID. Furthermore, the measurement parameters and / or reporting parameters of the CSI measurement report are determined based on the parameters configured in the mobility measurement report ReportConfig included in the MeasID.

[0075] When the second type of parameters includes AFRCN, PointA information for measuring reference signal resources is obtained according to AFRCN.

[0076] When the second type of parameters includes MeasConfig, the CSI reporting configuration obtains the measurement reference signal and reporting parameters based on the information configured in MeasConfig. For example, the reporting parameters include the parameters of the trigger event, and the measurement result obtained based on the measurement reference signal determines whether the trigger event is met. When the trigger event is met, the measurement result is reported in the UCI. Alternatively, the measurement index measID is determined based on the second type of parameters, and the reporting parameters are obtained based on the parameters configured in the reporting configuration (reportConfig) corresponding to the reporting configuration index (reportConfigId) included in the measID.

[0077] Furthermore, the measurement reference signal resources in the CSI-ReportConfig include at least one of the following: channel measurement reference signal resources, interference measurement reference signal resources, and the channel measurement reference signal and interference measurement reference signal resources in the CSI-ReportConfig can be configured separately (PCI, second type parameters), so that the channel measurement signal and the interference measurement signal can correspond to different (PCI, second type parameters), or the channel measurement reference signal and the interference measurement reference signal in the CSI-ReportConfig can share one (PCI, second type parameters). Further, the channel measurement reference signal of the CSI-ReportConfig includes one or more channel measurement reference signal resource sets, each set including one or more measurement reference signal resources. In this case, one or more channel measurement reference signal sets can share one (PCI, second type parameters), or each channel measurement reference signal resource set can be configured with a corresponding (PCI, second type parameters), or even each channel measurement reference signal resource in each set can be configured with a corresponding (PCI, second type parameters). Similarly, the first type of parameters can be configured separately for each interference measurement reference signal resource, and the first type of parameters can be configured separately for each interference measurement set. Of course, one or more interference measurement reference signal resource sets in the CSI-ReportConfig can also share a second type of parameter. Or the configuration level of the second type of parameter is different from the configuration level of the second type of parameter. For example, only one second type of parameter is configured in a CSI-ReportConfig, and the interference measurement signal and the channel measurement signal are shared, while the PCI is configured separately for the interference measurement signal and the channel measurement signal, or the PCI is configured separately for each interference signal resource set and / or each channel measurement signal resource set, or the PCI is configured separately for each interference signal measurement resource and / or each channel measurement resource.

[0078] In summary, the third type of parameters for the measurement reference signal resource are obtained using the second type of parameters, or the measurement reference signal is the mobility measurement reference signal corresponding to the first type of parameters. The measurement results obtained based on the measurement reference signal can be reported to the base station in the Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH). This allows the neighboring cell measurement results to be sent to the base station earlier.

[0079] In one embodiment, when the channel state information based on the mobility measurement reference signal is reported on the PUCCH or PUSCH using the method provided by this embodiment, the channel state information does not undergo the filtering process during the mobility measurement, that is, the channel state measurement result is an instantaneous measurement result, and a weighted average of multiple measurement results is not performed, especially a non-average weighted average of multiple measurement results is not performed.

[0080] The control signaling receiving method provided in this embodiment receives first control signaling including first-type parameters corresponding to a measurement reference signal, wherein the first-type parameters include a physical cell identifier or a physical cell identifier and second-type parameters. Thus, the measurement reference signal can be determined based on the first-type parameters to perform mobility measurement and report the measurement result through the physical layer. Since the measurement result reported through the physical layer has a low latency, the reporting latency of the mobility measurement result is reduced, thereby improving the cell switching speed.

[0081] Figure 2 A flowchart of another method for receiving control signaling provided in an embodiment is shown in FIG. Figure 2 As shown, the method provided in this embodiment includes the following steps.

[0082] Step S2010: Receive first control signaling, where the first control signaling includes first-type parameters corresponding to a sounding reference signal, wherein the first-type parameters include a physical cell identifier or a physical cell identifier and second-type parameters.

[0083] Step S2020: Receive second control signaling, where the second control signaling includes indication information, where the indication information is used to indicate that the first control signaling includes the first type of parameters corresponding to the measurement reference signal or includes the serving cell index corresponding to the measurement reference signal.

[0084] In this embodiment, after receiving the first control signaling, the first communication node may also receive a second control signaling, where the second control signaling is used to indicate that the first control signaling includes the first type of parameters corresponding to the measurement reference signal or includes the serving cell index corresponding to the measurement reference signal. In other words, in order for the first communication node to know that the first control signaling includes the first type of information or that the first control signaling includes the serving cell index corresponding to the measurement reference signal, in order not to increase the number of control signalings, the first control signaling may use existing signaling, but only add the first type of parameters thereto. In order for the first communication node to obtain the first type of parameters from the first control signaling, the second control signaling may be used to notify the first communication node.

[0085] In one embodiment, when the first control signaling includes the first type of parameters, the measurement reference signal resource index in the first control signaling is the index of the mobility measurement reference signal resource; when the first control signaling includes the serving cell index, the measurement reference signal resource index in the first control signaling is the index of the measurement reference signal resource in the serving cell; wherein the first control signaling includes CSI report configuration signaling.

[0086] Whether to configure the serving cell index in CSI-ReportConfig or to configure the above-mentioned first type of parameters is selected through signaling information. When configuring the serving cell index, the measurement reference signal included in CSI-ReportConfig belongs to the measurement reference signal configured in the serving cell, and / or the PointA information of the measurement reference signal resource is determined based on the PointA information configured in the serving cell, and / or the frequency domain resource where the measurement reference signal is located is within the BWP (BandWidth part) activated by the serving cell. When configuring the first type of parameters, the measurement reference signal in CSI-ReportConfig includes a mobility measurement reference signal, and the mobility measurement reference signal is determined based on the first type of parameters.

[0087] Step S2030: Determine a measurement reference signal according to the first type of parameters to perform measurement and report the measurement result through the physical layer.

[0088] In one embodiment, the measurement reference signal resource set includes at least one of the following sets: a measurement reference signal resource set configured in a serving cell; and a measurement reference signal resource set including mobility measurement reference signal resources.

[0089] In one embodiment, a measurement reference signal resource set includes measurement reference signals corresponding to different first-category parameters. A measurement reference signal resource is selected from the measurement reference signal resource set according to one of the following methods, and an index of the selected measurement reference signal resource is included in a UCI or a media access control element (MAC-CE) and reported: selecting a measurement reference signal resource from the measurement reference signal resource set based on a power difference between measurement reference signals corresponding to different first-category parameters; selecting a measurement reference signal resource from the measurement reference signal resource set based on a priority of the first-category parameters; selecting a measurement reference signal resource from the measurement reference signal resource set when the transmit powers of synchronization signals corresponding to all first-category parameters in the measurement reference signal resource set are the same; selecting a measurement reference signal resource from the measurement reference signal resource set while ignoring the transmit power of the measurement reference signal resource; obtaining the transmit power of the measurement reference signal resource corresponding to each first-category parameter, and selecting a measurement reference signal resource from the measurement reference signal resource set based on the transmit power of the measurement reference signal resource and the reception performance of the measurement reference signal at the receiving end.

[0090] In one embodiment, the uplink control signaling further includes at least one of the following information: a measurement configuration index, a measurement link index, a measurement target index, a serving cell measurement result list, a neighboring cell measurement result list, and a fifth-category parameter measurement result list. The serving cell measurement result list includes one or more serving cell measurement results, each serving cell measurement result including at least one of the following information: a serving cell index, cell measurement information corresponding to the serving cell, and cell measurement information corresponding to the best neighboring cell. The neighboring cell measurement result list includes one or more neighboring cell measurement results, each neighboring cell measurement result including at least one of the following information: a physical cell identifier and cell measurement information corresponding to the neighboring cell. The fifth-category parameter measurement result list includes one or more fifth-category parameter measurement results, each fifth-category parameter measurement result including at least one of the following information: a fifth-category parameter and cell measurement information corresponding to the fifth-category parameter.

[0104] In one embodiment, the UCI includes index information of the measurement reference signal resources in the measurement reference signal resource set. That is, the UCI includes selection information of the measurement reference signal in the measurement reference signal resource set.

[0105] In one embodiment, the method further includes: when the measurement result of the measurement reference signal is included in uplink control signaling, determining whether the measurement time of the measurement reference signal is restricted based on whether the first-category parameter corresponding to the measurement reference signal belongs to a predetermined first-category parameter set; wherein the uplink control signaling includes one of the following: UCI, uplink MAC-CE.

[0106] In one embodiment, it includes at least one of the following: when the first-category parameter belongs to a predetermined first-category parameter set, the measurement time of the measurement reference signal is not restricted; when the first-category parameter does not belong to the predetermined first-category parameter set, the measurement time of the measurement reference signal is restricted; wherein each first-category parameter set in the predetermined first-category parameter set is associated with a serving cell, and the measurement time is restricted including one of the following: the measurement time of the measurement reference signal falls within a measurement interval (MeasGap), and the synchronization signal in the measurement reference signal falls within a synchronization and physical broadcast channel measurement time configuration SSB measurement time configuration (SS / PBCH block measurement timing configuration, SMTC) time window.

[0107] In combination with various situations in the above embodiments, the signaling receiving method provided in this embodiment can ensure that the measurement reference signal resource of the CSI-ReportConfig includes the Mobility Measurement Reference Signal in one of the following ways.

[0108] Method 1: The measurement reference signal resources in the CSI-ReportConfig are selected from the serving cell measurement reference signal set list CSI-ResourceConfigId and the mobility measurement reference signal set list. The reference signals included in the serving cell measurement reference signal resource list belong to the reference signals configured in the serving cell, and the mobility measurement reference signal set list includes mobility measurement reference signals. One mobility measurement reference signal set list includes one or more mobility measurement reference signal sets, wherein the mobility measurement reference signal set includes one or more mobility measurement reference signals. In this method, whether the measurement reference signal resources in the CSI-ReportConfig are the serving cell measurement reference signal set list CSI-ResourceConfigId or the mobility measurement reference signal set list is further determined based on whether PCI information is configured. When the first type of parameters are configured in the CSI-ReportConfig, the measurement reference signal resources in the CSI-ReportConfig belong to the mobility measurement reference signal set list. When the CSI-ReportConfig only configures the serving cell index, the measurement reference signal in the CSI-ReportConfig belongs to the serving cell measurement reference signal set list.

[0109] Method 2: The measurement reference signal of CSI-ReportConfig includes a mobility measurement reference signal with a predetermined index CSI-RS index (CSI-RS-Index), and CSI-RS-Index is obtained according to the non-zero power CSI-RS resource index (NZP-CSI-RS-ResourceId), that is, NZP-CSI-RS-ResourceId is the same as the index of the mobility measurement reference signal, wherein NZP-CSI-RS-ResourceId is obtained according to the resource index configured in CSI-ResourceConfigId configured in CSI-ReportConfig. Furthermore, when PCI is not configured in CSI-ReportConfig, the measurement reference signal index configured in CSI-ReportConfig is the serving cell measurement reference signal index. When PCI is configured in CSI-ReportConfig, the measurement reference signal index configured in CSI-ReportConfig is the measurement reference signal index configured in Measobject (i.e., the mobility measurement reference signal index). Or when the PCI configured in CSI-ReportConfig belongs to a predetermined PCI set, the measurement reference signal index configured in CSI-ReportConfig is the serving cell measurement reference signal index; when the PCI configured in CSI-ReportConfig does not belong to the predetermined PCI set, the measurement reference signal index configured in CSI-ReportConfig is the mobility measurement reference signal index. Further, the predetermined PCI set includes one of the following: a set consisting of PCIs configured for the serving cell through RRC; a set consisting of PCIs activated for the serving cell; a PCI included in the transmission configuration indicator state (TCI state) information configured by RRC signaling; included in the TCI state information activated by MAC-CE; included in the TCI state information configured for a frequency domain bandwidth by RRC signaling; included in the TCI state information activated for a frequency domain bandwidth by MAC-CE. That is, according to whether the first type of parameters corresponding to the measurement reference signal or the serving cell index corresponding to the measurement reference signal is configured in CSI-ReportConfig, it is determined whether the measurement reference signal index included in the measurement reference set corresponds to the index of the serving cell measurement reference signal resource or the index of the mobility measurement reference signal resource.

[0110] Method 3: The reference signal in a measurement reference signal set list can be either a serving cell reference signal or a mobility measurement reference signal. The measurement reference signal set list and the mobility measurement reference signal set list containing the serving cell reference signal are numbered uniformly.

[0111] Furthermore, when the CSI-reported measurement reference signal includes a mobility measurement reference signal, it is necessary to determine a measurement reference signal set index and / or a measurement reference signal set list index to which the mobility measurement reference signal belongs. A measurement reference signal set list includes one or more measurement reference signal sets, and a measurement reference signal set includes one or more measurement reference signal resources. Specifically, the measurement reference signal set and / or measurement reference signal set list to which the mobility measurement reference belongs is determined in at least one of the following manners.

[0112] Method 1: When configuring a measurement reference signal resource (i.e., a mobility measurement reference signal resource) in a MeasObject, configure the measurement reference signal set identification information. Specifically, when configuring a CSI-RS-Resource-Mobility resource (as shown in Table 5) in a MeasObject, configure the resource with the measurement reference signal set list index CSI-ResourceConfigId or the measurement reference signal set index. This allows different mobility measurement reference signal resources corresponding to one PCI in a MeasObject to belong to different measurement reference signal sets.

[0113] Method 2: A PCI-configured measurement reference signal resource in MeasObject corresponds to a measurement reference signal set index or a measurement reference signal set list index. Specifically, when configuring a CSI-RS-CellMobility resource list (as shown in Table 4) for a PCI in MeasObject, configure the corresponding measurement reference signal set index and / or measurement reference signal set list index. The measurement reference signals in the csi-rs-ResourceList-Mobility corresponding to the cellId (i.e., PCI, Physical cellIndex) in Table 4 in the MeasObject belong to the same measurement reference signal set and / or the same measurement reference signal set list.

[0114] In the above-mentioned method 1 and method 2, it is further stipulated that mobility measurement reference signals associated with the same measurement reference signal set index in a MeasObject / MeasConfig belong to the same measurement reference signal set, so that a measurement reference signal set is allowed to include mobility measurement reference signals corresponding to different PCIs.

[0115] Mode 3: All mobility measurement reference signals corresponding to (PCI, Measobject) are used as measurement reference signal resources for the CSI-ReportConfig, for example, as channel measurement reference signal resources for the CSI-ReportConfig. In Table 4, no set index or set list index is configured. The first type of parameter is equivalent to the set index. That is, when determining the mobility measurement reference signal set, only the first type of parameter corresponding to the mobility measurement reference signal needs to be determined.

[0116] Method 4: Configure the measurement reference signal set list information in the Measobject. A Measobject may include one or more measurement reference signal set lists CSI-ResourceConfig, one or more measurement reference signal sets in a measurement reference signal set list, and a measurement reference signal set includes the mobility measurement reference signals configured in the Measobject, wherein the mobility measurement reference signals include one or more of CSI-RS and SSB. The measurement reference signals included in a measurement reference signal set set meet one of the following conditions: the PCIs corresponding to the measurement reference signals included in a set are the same; the PCIs corresponding to the measurement reference signals included in a set may be different, that is, the measurement reference signals included in a set include mobility measurement reference signals corresponding to multiple PCIs. In this case, the measurement reference signals included in a measurement reference signal set are represented by (PCI, measurement reference signal index).

[0117] Method 5: Configure the measurement reference signal set list in MeasConfig. A MeasConfig can include one or more measurement reference signal set lists. The measurement reference signals included in a measurement reference signal set meet one of the following conditions: the PCIs corresponding to the measurement reference signals included in a set are the same; the number of PCIs corresponding to the measurement reference signals included in a set can be greater than 1; the measurement reference signals included in a set have one MeasobjectID; the measurement reference signals included in a set include reference signals in one or more MeasobjectIDs. In this case, the measurement reference signals included in a measurement reference signal set are represented by (MeasObjectID, PCI, measurement reference signal index).

[0118] In methods 4 and 5, the measurement reference signal set list configuration information includes at least one of the following: a measurement reference signal set list index, a measurement reference signal resource set included in the measurement reference signal set list, and a mobility measurement reference signal included in the measurement reference signal set.

[0119] Method 6: In the measurement reference signal set list CSI-ResourceConfig included in the serving cell's CSI-MeasConfig, configure the corresponding PCI information or PCI and the second type of parameters for the CSI-RS / SSB resource. Specifically, the PCI information can be configured for the CSI-RS in one of the following ways.

[0120] A) Configure PCI information in the non-zero power CSI-RS measurement reference signal resource NZP-CSI-RS-Resource, that is, configure the corresponding PCI (or PCI and second-type parameters) for each CSI-RS resource. A set can include NZP-CSI-RS corresponding to multiple PCIs.

[0121] B) Configure the PCI in the non-zero-power CSI-RS measurement reference signal resource set NZP-CSI-RS-ResourceSet, i.e., all measurement reference signals in a set correspond to one PCI (or one PCI and second-type parameters). Configure the PCI in the CSI-ResourceConfig, i.e., all CSI-RSs in all sets in a CSI-ResourceConfig correspond to one PCI (or one PCI and second-type parameters), where a CSI-ResourceConfig includes one or more sets.

[0122] Specifically, one of the following methods may be used to configure PCI information for SSB.

[0123] 1) Configure the corresponding PCI (or a PCI and the second type of parameters) for each SSBIndex. A set can include SSBs corresponding to multiple PCIs.

[0124] 2) The corresponding PCI (or one PCI and second-type parameters) is configured in the CSI-SSB-ResourceSet. All SSBs in a set correspond to one PCI (or one PCI and second-type parameters).

[0125] 3) Configure PCI (or one PCI and second-type parameters) in CSI-ResourceConfig, that is, all SSBs in all sets in a CSI-ResourceConfig correspond to one PCI (or one PCI and second-type parameters), where one CSI-ResourceConfig includes one or more sets.

[0126] In one embodiment of the present application, when the channel state information obtained based on the SSB is used to report the channel state information of the physical layer (L1 layer) to the base station, it is determined whether the measurement time of the SSB is restricted by the SMTC based on the PCI corresponding to the SSB. For example, when the PCI corresponding to the SSB belongs to a predetermined PCI set, the measurement time of the SSB is not restricted by the SMTC, otherwise the measurement time of the SSB is restricted by the SMTC, wherein the predetermined PCI set includes one of the following: a set consisting of PCIs configured for the serving cell by RRC; a set consisting of PCIs activated for the serving cell; included in the TCI state information configured by RRC signaling; included in the TCI state information activated by MAC-CE; included in the TCI state information configured by RRC signaling for a frequency domain bandwidth; included in the TCI state information activated by MAC-CE for a frequency domain bandwidth. The measurement of the SSB is restricted by the SMTC, including that the SSB can only be measured in the SMTC window. In this embodiment of the present application, a frequency domain bandwidth includes one of the following: serving cell, CC (component carrier), BWP, PRB set. Furthermore, the channel state information obtained based on the SSB includes at least one of the following: RSRP, SINR, and RSRQ.

[0127] In one embodiment of the present application, when a measurement reference signal set includes multiple SSBs corresponding to the first type of parameters, the index information of the SSB is calculated based on the SSBs corresponding to the multiple first type of parameters. For example, the SSB resource indicator (SSBRI) reported by the terminal indicates the position of the combination (SSBIndex, first type of parameter) in an SSB set in this SSB set. Furthermore, the maximum number of SSBs included in an SSB set is greater than the maximum number of SSBs corresponding to a first type of parameter. For example, the maximum number of SSBs included in an SSB set is greater than 64. Therefore, when feeding back the SSBRI, the maximum number of feedback bits can be greater than 6. The first type of parameters includes one of the following: PCI, and combination information of PCI and second type of parameters.

[0128] In one embodiment of the present application, when a first-category parameter includes more than one SSB corresponding to a PCI, when selecting an SSBRI to report to the base station, one of the following methods is used to select the SSBR to be reported:

[0129] A) Assume that the transmit power (ss-PBCH-BlockPower) of the first type of parameters corresponding to all PCIs is the same;

[0130] B) The influence of ss-PBCH-BlockPower is not considered, for example, only the SSBRI is reported based on the RSRP / RSRQ / SINR corresponding to the SSB. In one embodiment, the SSBRI with the best RSRP / RSRQ / SINR is selected for reporting.

[0131] C) Obtain the ss-PBCH-BlockPower corresponding to each first-category parameter, and report the SSBRI based on the ss-PBCH-BlockPower and the RSRP / RSRQ / SINR corresponding to the SSB. In one embodiment, the SSBRI with the largest difference between the ss-PBCH-BlockPower and the RSRP / RSRQ / SINR is selected for reporting.

[0132] In one embodiment, if the mobility measurement reference signal result is included in the UCI information and reported, the PUCCH resource or PUSCH resource containing the UCI information is configured. Specifically, for example, the PUCCH resource index or PUSCH resource containing the mobility measurement result corresponding to the MeasID is configured in MeasID (or MeasConfig), such as the PUCCH resource index, the time domain characteristics of the PUCCH resource, and the serving cell index of the PUCCH resource. The time domain characteristics include at least one of periodic, aperiodic, and semi-persistent.

[0133] In one embodiment, the UCI includes at least one of the following information: MeasID, MeasObjectID, a serving cell measurement result list, and a neighboring cell measurement result list. The serving cell measurement result list includes one or more serving cell measurement results, and each serving cell measurement result includes at least one of the following information: a serving cell index, serving cell measurement information, and best neighboring cell measurement information. The neighboring cell measurement result list includes one or more neighboring cell measurement results, and each neighboring cell measurement result includes at least one of the following information: PCI, and cell measurement information. One or more of the serving cell measurement information, neighboring cell measurement information, and cell PCI measurement information includes at least one of the following information: the RSRP / RSRQ / SINR corresponding to the PCI, a measurement reference signal resource index list, and the RSRP / RSRQ / SINR corresponding to the measurement reference signal resources in the measurement reference signal resource index list. The RSRP / RSRQ / SINR corresponding to a cell is obtained based on the average measurement results of one or more measurement reference signal resources in the cell, and the measurement reference signal resources in the measurement reference signal resource index list belong to the measurement reference signal set corresponding to the PCI. Alternatively, the UCI includes at least one of the following information: MeasID, MeasObjectID, PCI list, measurement results corresponding to each PCI, where the measurement results corresponding to one PCI include at least one of the following: RSRP / RSRQ / SINR corresponding to the PCI, a measurement reference signal resource index list, and RSRP / RSRQ / SINR corresponding to the measurement reference signal resources in the measurement reference signal resource list. The RSRP / RSRQ / SINR corresponding to the cell is obtained based on the average measurement results of one or more measurement reference signal resources in the cell, and the measurement reference signal resources in the measurement reference signal resource index list belong to the measurement reference signal set corresponding to the PCI. Furthermore, the UCI is reported in the PUCCH or PUSCH.

[0134] In one embodiment, the terminal reports mobility measurement results via MAC-CE signaling. Furthermore, the MAC-CE includes L1-RSRP / L1-SINR / L1-RSRQ results obtained based on a mobility measurement reference signal, where L1-RSRP / L1-SINR / L1-RSRQ are not filtered at the RRC layer. L1-RSRP, L1-SINR, and L1-RSRQ represent RSRP, SINR, and RSRQ at the physical layer, respectively. Alternatively, the MAC-CE includes RSRP / SINR / RSRQ results obtained based on a mobility measurement reference signal, where RSRP / SINR / RSRQ results are filtered at the RRC layer. That is, the mobility measurement results stored by the terminal are reported via MAC-CE signaling. Alternatively, the MAC-CE includes at least one of the following information: MeasID, a serving cell measurement result list, and a neighboring cell measurement result list. The serving cell measurement result list includes one or more serving cell measurement results, and a serving cell measurement result includes at least one of the following information: a serving cell index, serving cell measurement information, and best neighboring cell measurement information. The neighboring cell measurement result list includes one or more neighboring cell measurement results, and a neighboring cell measurement result includes at least one of the following information: PCI, cell measurement information. The one or more of the serving cell measurement information, neighboring cell measurement information, and cell PCI measurement information include at least one of the following information: RSRP / RSRQ / SINR corresponding to the PCI, a measurement reference signal resource index list, and RSRP / RSRQ / SINR corresponding to the measurement reference signal resources in the measurement reference signal resource list. The RSRP / RSRQ / SINR corresponding to the cell is obtained based on the average measurement results of one or more measurement reference signal resources in the cell, and the measurement reference signal resources in the measurement reference signal resource index list belong to the measurement reference signal set corresponding to the PCI. Alternatively, the MAC-CE includes at least one of the following information: MeasID, PCI list, and measurement results corresponding to each PCI, wherein a measurement result corresponding to a PCI includes at least one of the following information: RSRP / RSRQ / SINR corresponding to the PCI, a measurement reference signal resource index list, and RSRP / RSRQ / SINR corresponding to the measurement reference signal resources in the measurement reference signal resource list. The RSRP / RSRQ / SINR corresponding to the cell is obtained based on the average of the measurement results of one measurement reference signal resource or multiple measurement reference signal resources in the cell, wherein the measurement reference signal resources in the measurement reference signal resource index list belong to the measurement reference signal set corresponding to the PCI.

[0135] In one embodiment, when a serving cell corresponds to multiple first-category parameters, it is necessary to determine the mobility measurement reference signal corresponding to which first-category parameter a serving cell mobility measurement result is obtained. For example, during mobility measurement, it is necessary to report the mobility measurement result of the serving cell, or it is necessary to determine whether an event is met to determine whether to report the mobility measurement result. If reported, the mobility measurement result of the serving cell needs to be reported. Each of the multiple first-category parameters corresponds to a measurement reference signal set. For example, they correspond to the CSI-RS corresponding to the PCI configured in Table 4, and the measurement reference signal corresponding to each PCI includes the CSI-RS configured in Table 4 and may also include the SSB configured in Table 2. The first-category parameters include one of the following: PCI, PCI and second-category parameters. The following description takes the first-category parameters including PCI as an example, and the following method is also applicable to the case where the first-category parameters include PCI and second-category parameters.

[0136] Furthermore, when it is necessary to report the serving cell's measurement results in the Mobility measurement results (MeasResults), one of the following methods can be used:

[0137] Method 1: Report the corresponding mobility measurement result for each of the multiple PCIs of the serving cell. Specifically, the service measurement result (MeasResultServMO) in MeasResults includes multiple serving cell measurement results (measResultServingCell), where different measResultServingCells correspond to different PCIs, and the PCI is included in the reporting information of each measResultServingCell.

[0138] Method 2: Select one of the multiple PCIs corresponding to the serving cell and report the mobility measurement result corresponding to the selected PCI. Specifically, the selection of one of the multiple PCIs can be done in one of the following ways: terminal implementation issue; select the PCI with the best performance.

[0139] Method 3: Report the mobility measurement result corresponding to the primary PCI of the serving cell, where the primary PCI of a serving cell is obtained through one of the following methods: PCI configured in the serving cell common configuration (ServingCellConfigCommon); PCI configured in the serving cell common configuration system information block (ServingCellConfigCommonSIB); PCI selected by the physical random access channel (PRACH); PCI corresponding to the first TCI state in the activated TCI state, where the activated TCI state includes the TCI state activated for the physical downlink shared channel (PDSCH) in a BWP; PCI corresponding to the first CORESET group, preferably, the first CORESET group includes the CORESET group with the lowest CORESET group index; lowest PCI.

[0140] The measurement result corresponding to the above-mentioned PCI includes at least one of the following: RSRP / RSRQ / SINR corresponding to the PCI, a measurement reference signal resource index list, and RSRP / RSRQ / SINR corresponding to the measurement reference signal resource in the measurement reference signal resource list. The RSRP / RSRQ / SINR corresponding to the cell is obtained by averaging the measurement results of one or more measurement reference signal resources in the cell, wherein the measurement reference signal resources in the measurement reference signal resource index list belong to the measurement reference signal set corresponding to the PCI, such as the CSI-RS corresponding to the PCI described in Table 4. Of course, the measurement reference signal set corresponding to the PCI may also include the SSB configured in Table 2.

[0141] Event-based mobility measurement includes the following events: {EventA1, EventA2, EventA3, EventA4, EventA5, EventA6}. These events all include the performance of serving cells, where serving cells include one or more of primary cells and secondary cells. When determining the performance of a serving cell, if a serving cell corresponds to multiple PCIs, one or more of the following methods can be used:

[0142] Method 1: The performance of the serving cell is obtained based on the mobility reference signals corresponding to multiple PCIs of the serving cell. For example, the measurement results of up to N mobility reference signals in a mobility reference signal set consisting of mobility reference signals corresponding to multiple PCIs are averaged to obtain the measurement result of the serving cell.

[0143] Method 2: Select one of the multiple PCIs corresponding to the serving cell, and the performance of the serving cell is the performance corresponding to the selected PCI. For example, the performance of the PCI with the best (or worst) performance among the multiple PCIs is selected as the performance of the serving cell, and the performance of the one PCI is the performance obtained based on the mobility measurement reference signal of the PCI.

[0144] Method 3: The performance corresponding to the primary PCI of the serving cell is used as the performance of the serving cell, and the primary PCI of one serving cell is obtained through one of the following methods: PCI configured in ServingCellConfigCommon; PCI configured in ServingCellConfigCommonSIB; PCI selected by PRACH; PCI corresponding to the first TCI state in the activated TCI state, where the activated TCI state includes the TCIstate activated for the PDSCH in a BWP; PCI corresponding to the first CORESET group, preferably, the first CORESET group includes the CORESET group with the lowest CORESET group index, PCI.

[0145] Method 4: Based on the serving cell.

[0146] Furthermore, the multiple PCIs corresponding to a service cell include one of the following: multiple PCIs configured for a service cell through RRC signaling; multiple PCIs activated for a service cell through MAC-CE signaling; multiple PCIs included in the TCI state configured for a service cell through RRC signaling; multiple PCIs included in the TCI state activated for a service cell through MAC-CE signaling; multiple PCIs included in the TCI state configured for a BWP of a service cell through RRC signaling; multiple PCIs included in the TCI state activated for a BWP of a service cell through MAC-CE signaling, wherein the multiple PCIs are included in the TCI state, the multiple PCIs included in the above-mentioned configured or activated TCI state include multiple PCIs included in the TCI state with the same TCI state index, or multiple PCIs included in the TCI state with different TCI state indexes. The above-mentioned mobile measurement result may be included in one of the following: RRC signaling, MAC-CE signaling, and UCI.

[0147] In one embodiment, when configuring the beam failure candidate reference signal of the serving cell, the mobility measurement reference signal is included. Furthermore, when the serving cell is the primary cell (primary cell), and the beam failure candidate reference signal of the primary cell includes the mobility measurement reference signal, a correspondence between the mobility measurement reference signal and the PRACH resource is established. The beam failure candidate reference signal of the serving cell indicates that when a beam failure is detected based on the beam failure detection reference signal of the serving cell, a candidate reference signal is selected from the beam failure candidate reference signal set, and the selected candidate reference signal information is reported to the base station. Preferably, different candidate reference signals represent different transmit beams, and the base station knows the preferred beam selected by the terminal based on the candidate reference signal information reported by the terminal. When the serving cell is the primary cell, since the correspondence between the candidate reference signal and the PRACH resource is established, the terminal does not directly report the selected candidate reference signal index information, but based on which PRACH resource the terminal sends the PRACH signal on, the base station can know which candidate reference signal the terminal has selected.

[0148] When the serving cell is the primary cell, starting at a predetermined time after reporting the candidate reference signal information (i.e., sending the PRACH signal), the quasi-co-located reference signal of the beam failure detection CORESET in the primary cell is determined as the selected candidate reference signal. When the selected candidate reference signal is the mobility measurement reference signal, the quasi-co-located reference signal of the beam failure detection CORESET of the primary cell is determined as the selected mobility measurement reference signal. The beam failure detection CORESET includes the CORESET associated with the beam failure detection search space.

[0149] When the serving cell is a secondary cell, the terminal reports the information in the PUCCH Beam Failure Recovery (PUCCH-BFR) when it detects a beam failure in the secondary cell. After receiving the PUCCH-BFR, the base station knows that a beam failure has occurred in the secondary cell, but does not know which secondary cell has experienced the beam failure. The base station allocates a PUSCH channel to the terminal. The terminal includes the secondary cell index and the candidate reference signal index information selected for the secondary cell in the PUSCH allocated by the base station. When the terminal receives a Hybrid Automatic Repeat reQuest (HARQ) process number that is the same as that of the PUSCH, but the data indication is downlink control information (DCI) for new data transmission (hereinafter referred to as the response information to the new reference signal indication information), the terminal considers that the PUSCH transmission is successful. Starting at a predetermined time after receiving the DCI, the terminal determines the secondary The quasi-co-located reference signals of all CORESETs in the cell are selected as candidate reference signals. When the selected candidate reference signal is a mobility reference signal, the terminal determines the quasi-co-located reference signals of all CORESETs in the secondary cell as the selected mobility measurement reference signals.

[0150] Specifically, the beam failure candidate reference signal of the serving cell, including the mobility measurement reference signal, is reflected in one of the following ways:

[0151] 1) Beam failure candidate reference signals include the reference signals configured in MeasObject;

[0152] 2) When configuring candidate reference signals, not only the SSB / CSI-RS index but also PCI information is included. For example, when the serving cell is the primary cell, the BFR-SSB resource (BFR-SSB-Resource) includes not only the SSB index (SSBIndex) but also PCI information. The BFR-CSI-RS resource (BFR-CSIRS-Resource) includes not only the CSI-RS index but also PCI information.

[0153] 3) When configuring candidate reference signals, not only the SSB / CSI-RS index but also PCI information and the second type of parameters are included.

[0154] Through the above method, the beam failure candidate reference signal of the serving cell includes the Mobility Measurement Reference Signal. Therefore, when a beam failure occurs in the serving cell, the Mobility Measurement Reference Signal of a non-serving cell can be selected, allowing the terminal to switch to the non-serving cell and quickly recover the link between the base station and the terminal. Alternatively, the terminal can switch to the Mobility Measurement Reference Signal of the serving cell, which generally has a relatively wide beam.

[0155] Furthermore, the PCI corresponding to the candidate reference signal does not belong to a predetermined PCI set, wherein the predetermined PCI set includes one of the following: a set consisting of PCIs configured for the serving cell through RRC; a set consisting of PCIs activated for the serving cell; included in the TCI state information configured by RRC signaling; included in the TCI state information activated by MAC-CE; included in the TCI state information configured for a frequency domain bandwidth by RRC signaling; included in the TCIstate information activated for a frequency domain bandwidth by MAC-CE. The measurement of SSB is subject to the restrictions of SMTC, including that SSB can only be measured within the SMTC window. This means that when a mobile measurement reference signal is configured as a beam failure candidate reference signal, the PCI corresponding to the mobile measurement reference signal does not belong to the serving cell PCI, or when the PCI corresponding to the beam failure candidate reference signal is not configured, the PCI corresponding to the beam failure candidate reference signal is obtained based on the PCI corresponding to the serving cell corresponding to the beam failure candidate reference signal.

[0156] Furthermore, when the candidate reference signal set includes both a serving cell measurement reference signal and a non-serving cell measurement reference signal, the terminal prioritizes the serving cell measurement reference signal. When the terminal cannot select a serving cell measurement reference signal from the serving cell measurement reference signal, the terminal selects a non-serving cell measurement reference signal. The non-serving cell measurement reference signal includes one of the following: a mobile measurement reference signal configured in the MeasObject, and a mobile measurement reference signal corresponding to a PCI configured in the MeasObject that does not belong to a predetermined PCI set.

[0157] Furthermore, when the new reference signal resource selected in the candidate reference signal resource set belongs to the reference signal in the serving cell, a first quasi-co-location relationship is established starting from the first predetermined time after the first moment; when the new reference signal resource selected in the candidate reference signal resource set belongs to the mobile measurement reference signal resource, a first quasi-co-location relationship is established starting from the second predetermined time after the first moment, wherein the first quasi-co-location relationship includes that the demodulation reference signal of the CORESET associated with the beam failure search space and the new reference signal resource satisfy a quasi-co-location relationship, and that the demodulation reference signal of the PDSCH scheduled in the CORESET associated with the beam failure search space and the new reference signal resource satisfy a quasi-co-location relationship. For the beam failure process of the primary serving cell, the first moment includes the terminal sending new reference signal resource indication information to the base station (i.e., sending PRACH); for the beam failure process of the secondary serving cell, the first moment includes the start of the above-mentioned response information to the new reference signal indication information.

The first communication node is, for example, a terminal, and the second communication node is, for example, a base station. The inter-cell measurement method provided in this embodiment is Figure 1The processing on the base station side corresponding to the receiving method of the control signaling shown.

The measurement reference signal determined according to the first type of parameter is not only the measurement reference signal of the service cell, but can be other measurement reference signals corresponding to the first type of parameter. Then the first communication node can perform mobility measurement based on the measurement reference signal of the non-service cell, and the mobility measurement result can be sent to the second communication node of the network layer, that is, the base station, through physical layer signaling, thereby reducing the reporting delay of the mobility measurement result.

This enables a node that receives the first control signaling to determine a measurement reference signal based on the first-type parameters to perform mobility measurement and report the measurement results through the physical layer. Since the measurement results reported through the physical layer have a low latency, the reporting latency of the mobility measurement results is reduced, thereby improving the cell switching speed.
