Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a method for measuring and reporting channel state information, a terminal, and network-side equipment. Background Technology

[0002] In existing cell handover scenarios, after receiving higher-layer handover signaling carrying common configurations, the terminal performs coarse synchronization and Automatic Gain Control (AGC) adjustments by detecting the target cell's Synchronization Signal Block (SSB). Then, it performs uplink synchronization and accesses the target cell by sending Random Access Channel (RACH) information. After successfully accessing the target cell, the terminal receives dedicated configuration information from the network side, such as Channel State Information Reference Signal (CSI-RS), Tracking Reference Signal (TRS), and physical resources like channels. It performs fine time-frequency synchronization and AGC adjustments by detecting the TRS, and then measures the CSI-RS and reports the Channel State Information (CSI) to the network side. The network side schedules downlink transmission based on the CSI information reported by the terminal, at which point the downlink of the target cell becomes effective.

[0003] Because downlink scheduling transmission in the target cell can only occur after CSI measurement and reporting, the terminal can only obtain the target cell's CSI-RS resource configuration information after successfully handing over to the target cell. Before completing CSI measurement and reporting, the terminal cannot perform downlink scheduling transmission, thus significantly increasing downlink interruption time. Summary of the Invention

[0038] First, let's introduce the principle of Rel-16 CSI:

[0039] CSI reports can be configured as follows:

[0040] 1. Periodic CSI Report (P-CSI): Transmitted only on the Physical Uplink Control Channel (PUCCH);

[0041] 2. Semi-Continuous CSI Reporting (SP-CSI): Transmitted on PUCCH or the Physical Downlink Shared Channel (PUSCH). SP-CSI reporting based on PUSCH is activated and deactivated by the CSI Request field in the Downlink Control Information (DCI) signaling. Radio Resource Control (RRC) can configure up to 64 trigger states, each corresponding to a CSI Report Setting. During CSI acquisition, each CSI Report Setting is associated with a resource setting containing only one CSI-RS resource set.

[0042] 3. Aperiodic CSI Reporting (A-CSI): Transmitted only on the PUSCH. PUSCH-based A-CSI reporting is activated by DCI signaling. RRC configures multiple trigger states, each corresponding to one or more CSI report settings. The CSI request field in DCI triggers a trigger state. The maximum configuration of the CSI request field in DCI format 0_1 ​​is 6 bits, thus supporting a maximum of 64 CSI trigger states. When the number of CSI trigger states configured by RRC exceeds 64, MAC CE signaling maps 64 of these trigger states to the CSI request field. Each CSI trigger state can be associated with 1 to 3 resource settings. If a resource setting contains multiple resource sets, only one resource set is selected. The quasi-co-location (QCL) information of the CSI-RS resources in this resource set is configured for each resource by the Transmission Configuration Indicator (TCI) status.

[0043] The CSI resource settings are as follows:

[0044] 1. M ≥ 1 resource setting;

[0045] 2. A resource configuration contains S ≥ 1 CSI-RS resource sets;

[0046] 3. A resource set contains Ks≥1 RS resources, such as CSI-RS / CSI Interference Measurement (CSI-IM) resources;

[0047] 4. One CSI-RS resource is used to configure the number of CSI-RS ports and time-frequency location information, etc.; one CSI-IM resource is used to configure the time-frequency location information of CSI-IM, etc.

[0048] Next, the Rel-16 CSI measurement resources will be introduced:

[0049] The measurement resources are as follows:

[0050] 1. Interference measurement based on CSI-IM;

[0051] 2. Interference and channel measurements based on non-zero power CSI-RS (NZP CSI-RS).

[0052] Period and slot offset:

[0053] 1. Periodic and semi-persistent CSI-RS, where the period and slot offset are configured by RRC signaling;

[0054] 2. Semi-persistent NZP CSI-RS / CSI-IM uses MAC CE for activation and deactivation;

[0055] 3. Aperiodic CSI-RS, triggered by DCI, and the candidate value of the slot offset of CSI-RS is configured independently by RRC signaling in each resource set in the measurement resource setting, and one of the candidate values ​​is indicated by DCI signaling as the CSI-RS transmission time.

[0056] SP-CSI reported:

[0057] Channel measurements can be performed using periodic or semi-persistent CSI-RS, and interference measurements can be performed using periodic or semi-persistent CSI-IM accordingly. Interference measurements using NZP CSI-RS are not supported.

[0058] A-CSI reporting:

[0059] Channel measurements can be performed using periodic, semi-persistent, or aperiodic CSI-RS, and interference measurements can be performed using periodic, semi-persistent, or aperiodic CSI-IM accordingly. Interference measurements using NZP CSI-RS are also supported.

[0060] Next, the contents of the CSI report will be introduced:

[0061] Terminals can use CSI-ReportConfig to configure the higher-level parameter reportQuantity to be set to 'none', 'cri-ri-pmi-cqi', 'cri-RI-i1', 'cri-RI-CQI', 'cri-RSRP', 'cri-SINR', 'ssb-Index-RSRP', 'ssb-Index-SINR', or 'cri-RI-LI-PMI-CQI'.

[0062] If the terminal is configured with CSI-ReportConfig and the upper-level parameter reportQuantity is set to "none", then the terminal will not report anything for CSI-ReportConfig.

[0063] If the terminal is configured with CSI-ReportConfig and the upper-layer parameter reportQuantity is set to 'cri-RI-PMI-CQI' or 'cri-RI-LI-PMI-CQI', the terminal should report a precoding matrix for the entire reporting band, or a precoding matrix for each sub-band.

[0064] If the terminal is configured with CSI-ReportConfig and the upper-layer parameter reportQuantity is set to 'cri-RI-i1-CQI', the UE should report a PMI, which includes a single broadband indication of the entire CSI reporting band.

[0065] Next, the CSI handling guidelines will be introduced:

[0066] The terminal's ability to process CSI reports, i.e., the number N CSIs it can simultaneously calculate. CPU This needs to be reported to the network. If a terminal supports N... CPU The simultaneous calculation of CSI means that the terminal has N CPU One CSI processing unit is used to process CSI reports for all configured cells.

[0067] Number of available CPUs: In a given Orthogonal Frequency Division Multiplexing (OFDM) symbol, if L CPUs are already occupied processing CSI reports, then the UE has N CPUs available. CPU -L available CPUs. If there are N CSI reports to start occupying CPUs on this OFDM symbol, the nth CSI report (n=0,…,N-1) requires CPU time. If the number of available CPUs is less than the number of CPUs required for N CSI reports, then the UE does not need to update NM low-priority CSI reports, where 0 ≤ M ≤ N is a condition that satisfies... The maximum value.

[0068] The CPU usage of CSI reports is shown in Table 1:

[0069] Table 1

[0070]

[0071] In Table 1 above, K s The number of CSI-RS resources included in the CSI-RS resource set for channel measurements.

[0072] CPU usage time: The start and end OFDM symbols of CPU usage reported by CSI are summarized in Table 2 below:

[0073] Table 2

[0074]

[0075]

[0076] In Table 2 above, Case 1 refers to the first transmission of a PUSCH-based SP-CSI report activated by PDCCH.

[0077] Next, the CSI calculation time will be discussed:

[0078] When the CSI request field in the DCI triggers one or more CSI reports transmitted via PUSCH, the terminal can provide a valid CSI report if the following two conditions are met:

[0079] If, after taking timing lead, the first uplink OFDM symbol (hereinafter referred to as "symbol") of the CSI report is transmitted at a time no earlier than symbol Z... ref And no earlier than Z' ref ,in:

[0080] Z ref Defined as the last symbol of the PDCCH that triggers the CSI report, followed by ((Z+d)(2048+144)·κ2. -μ )·T C The next up sign after the time (seconds) includes the control plane (CP);

[0081] Z' ref Defined as follows when the triggered CSI report n is based on aperiodic CSI-RS: (1) the last symbol of the aperiodic CSI-RS for channel measurement; (2) the last symbol of the aperiodic CSI-IM for interference measurement; (3) the last symbol of the aperiodic NZP CSI-RS for interference measurement, and the last symbol of the three is followed by ((Z'+d)·(2048+144)·κ2. -μ )·T C The next up sign after the time (seconds) includes the CP;

[0082] The value of d is related to whether the CSI report contains PUSCH multiplexing that includes transport data blocks or HARQ-ACK or both, as well as the numerical configuration (numerology) μ.

[0083] like Figure 2 The figure shows a schematic diagram of the non-periodic CSI report triggering timing when d=0.

[0084] If the first uplink symbol of the PUSCH used by one or more CSI reports that trigger PUSCH transmission in the CSI request field of the DCI does not meet the above conditions, the terminal may ignore the DCI, not update the CSI, or discard the CSI report, depending on the specific circumstances.

[0085] When the number of currently idle CSI processing units (CPUs) on the terminal is sufficient to compute M CSI reports, Z = max m＝0,…,M-1 (Z m Z′=max m＝0,…,M-1 (Z′ m (Z) m ,Z′ m The value corresponds to the m-th CSI report. Based on the complexity of CSI calculation and the number of unused CPUs, the protocol provides (Z, Z′) corresponding to the calculation times of two types of CSI, namely low-latency CSI (latency requirement 1) and high-latency CSI (latency requirement 2), which are listed in Tables 3 and 4 respectively.

[0086] Table 3 Low Latency CSI (Latency Requirement 1)

[0087]

[0088] Table 4 High Latency CSI (Latency Requirement 2)

[0089]

[0090] If the first uplink symbol of the PUSCH used by one or more CSI reports that trigger PUSCH transmission in the CSI request field of the DCI does not meet the above conditions, the UE may ignore the DCI, not update the CSI, or discard the CSI report, depending on the specific circumstances.

[0091] μ = min(μ) in Table 3 or Table 4 PDCCH ,μ CSI-RS ,μ UL ), where: μ PDCCH The subcarrier spacing of the PDCCH corresponding to the DCI that triggers the CSI report, μ UL The subcarrier spacing corresponding to the PUSCH used for transmitting CSI reports, μ CSI-RS The minimum subcarrier spacing corresponding to the aperiodic CSI-RS triggered by DCI.

[0092] Table 5 Supported transmission value configurations

[0093]

[0094] The terminal does not expect to receive more than one non-periodic CSI report request in a single time slot, meaning that regardless of whether it is a CA or non-CA scenario, the terminal will not transmit a non-periodic CSI report triggered by multiple DCI CSI report requests in a single time slot.

[0095] In the above formula, the time unit is T. c =1 / (Δf) max ·N f ) seconds (s), Δf max =480·10 3 Hertz (Hz), N f =4096. Constant κ = 64.

[0096] Next, the CSI reference resources will be introduced:

[0097] The CSI reference resource definition for a serving cell is as follows:

[0098] 1. In the frequency domain, CSI reference resources are defined as a set of downlink physical resource blocks over the bandwidth used to acquire CSI;

[0099] 2. In the time domain, for an uplink CSI reporting slot n', the CSI reference resource is a downlink slot nn. CSI_ref ,in And μ DL and μ UL These represent the uplink and downlink subcarrier spacing configurations, respectively.

[0100] Among them, for periodic and semi-persistent CSI reporting,

[0101] 1. If there is only one CMR or SSB resource, n CSI_ref For a greater than or equal to The minimum value, and corresponding to a valid downlink time slot;

[0102] 2. If there are multiple CMR or SSB resources, n CSI_ref For a greater than or equal to The minimum value, and corresponding to a valid downlink time slot;

[0103] For non-periodic CSI reporting, if the DCI instructs the user to report CSI in the same time slot as the CSI request, n CSI_ref Ensure that the reference resource defined in a valid downlink slot is the same as the corresponding CSI request; otherwise, n CSI_ref For a greater than or equal to The minimum value of Z' corresponds to a valid downlink time slot, where Z' corresponds to a latency requirement.

[0104] When periodic or semi-persistent CSI-RS / CSI-IM or SSB resources are used for channel or interference measurements, the UE does not expect the last OFDM symbol of the received measurement channel or interference resource to be less than Z' symbols away from the first OFDM symbol reported by the aperiodic CSI.

[0105] Finally, the priority of CSI reports will be introduced:

[0106] A CSI report has the following priority parameters:

[0107] Pri iCSI (y,k,c,s)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s

[0108] Where y=0 indicates that an aperiodic CSI report will be performed on PUSCH, y=1 indicates that a semi-persistent CSI report will be performed on PUSCH, y=2 indicates that a semi-persistent CSI report will be performed on PUCCH, and y=3 indicates that a periodic CSI report will be performed on PUCCH.

[0109] k=0 indicates a CSI report carrying L1 reference signal received power or L1 signal-to-noise ratio, and k=1 indicates a CSI report not carrying L1 reference signal received power or L1 signal-to-noise ratio.

[0110] c represents the serving cell index, N cells This represents the value of the higher-level parameter maxNrofServingCells;

[0111] s represents the report configuration identifier reportConfigID, M s The value of the high-level parameter maxNrofCSI-ReportConfigurations is identified.

[0112] Priority parameter value Pri icsI The smaller (y,k,c,s) is, the higher the priority of the corresponding CSI report.

[0113] The channel state information measurement and reporting method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0114] Figure 3 This is one of the flowcharts illustrating the channel state information measurement and reporting method provided in this application embodiment. For example... Figure 3 , Figure 4 As shown, the method provided in this embodiment includes:

[0115] Step 301: The terminal receives the target signaling sent by the network-side device and determines the reference signal RS resource of the first object based on the target signaling; wherein, the target signaling is the signaling obtained before the terminal accesses the first object.

[0116] Specifically, the first object can be a target transmission reception point (TRP), a target cell, or a target cell group. The target signaling is the signaling acquired before the terminal accesses the first object. That is, by advancing the acquisition time of the target signaling from "after the terminal accesses the first object" to "before the terminal accesses the first object", the target signaling can be acquired quickly, and further, the RS resources of the first object can be acquired quickly.

[0117] Step 302: The terminal performs CSI measurement and reporting based on the RS resources of the first object.

[0118] Specifically, after acquiring the RS resources of the first object, the terminal performs CSI measurement and reporting based on the RS resources of the first object, and obtains a CSI report.

[0119] In this embodiment, the terminal can acquire target signaling before accessing the first object, determine the reference signal (RS) resources of the first object based on the target signaling, and perform CSI measurement and reporting based on the RS resources of the first object. Since the acquisition time of the target signaling is advanced from "after the terminal accesses the first object" to "before the terminal accesses the first object", the CSI report of the first object can be reported quickly, enabling the terminal to perform downlink transmission and reception as soon as possible after completing cell handover, reducing downlink interruption time.

[0120] In step 301 above, the terminal can determine the reference signal RS resources of the first object based on the target signaling in several ways, including the following:

[0121] Method 1:

[0122] The target signaling includes a first signaling, which is used to indicate the configuration information of multiple objects, including the first object, or the first object and the current service object, wherein the first object is different from the current service object.

[0123] Specifically, the multiple objects included in the first signaling include a first object, or a first object and a current serving object. The current serving object is the current serving TRP, the current serving cell, or the current serving cell group. The first object is a target TRP, target cell, or target cell group that is different from the current serving object among the multiple objects included in the first signaling.

[0124] Optionally, the configuration information for multiple objects includes higher-layer configuration information and / or physical-layer configuration information. The higher-layer configuration information includes at least one of the following: cell group configuration information, special cell configuration information, synchronization reconfiguration information, serving cell common configuration information, and serving cell configuration information. The physical-layer configuration information includes at least one of the following: RS resource configuration information, CSI-reported configuration information, frequency domain information, subcarrier spacing (SCS) information, Cell Radio Network Temporary Identifier (C-RNTI) information, Physical Uplink Control Channel (PUCCH) information, configuration grant information, Path Loss Reference Signal (PL-RS) information, Random Access Channel (RACH) resource information, Quasi-co-location (QCL) information, and spatial relationship information. The CSI-reported configuration information in the current serving object's configuration information is associated with the RS resources of the first object, and the frequency domain information includes at least one of the following: Synchronization Signal Block (SSB) frequency information, CSI-RS frequency information, and frequency band indication information.

[0125] Optionally, in step 301 above, the terminal determines the reference signal RS resource of the first object based on the target signaling, including:

[0126] The terminal determines the first object based on the multiple objects included in the first signaling;

[0127] The terminal determines the RS resource of the first object based on the configuration information of multiple objects included in the first signaling.

[0128] Specifically, the terminal takes all or part of the objects that are different from the current service object among the multiple objects included in the first signaling as the first object, and for each first object, the terminal determines the RS resource of the first object based on the configuration information of the RS resource of the first object included in the first signaling. That is, the terminal can determine the RS resource of at least one first object based on the first signaling.

[0129] In one specific embodiment, after the terminal receives the RRC pre-configuration information carrying N (N≥1) candidate objects, each candidate object is a first object, and the CSI-RS for CSI and TRS of all first objects take effect immediately. The terminal can obtain the accurate time-frequency synchronization information of the first object through the TRS of each first object, obtain the CSI report through the CSI-RS of each first object, and report to the current service object or the first object.

[0130] Optionally, the method in this embodiment further includes: the terminal determining the start and end time of the RS resource of the first object taking effect according to a first preset rule; the first preset rule includes: the RS resource of the first object takes effect after the terminal receives the first signaling and becomes invalid after the terminal receives the signaling to release the RS resource configuration of the first object.

[0131] Specifically, when the RS resource is a periodic RS resource, the start time of the RS resource activation of the first object is no earlier than the time when the terminal receives the radio resource control signaling containing the configuration information of the RS resource (i.e., the first signaling), and the end time of the RS resource activation of the first object is no later than the time when the terminal receives the radio resource control signaling containing the configuration information of the RS resource release.

[0132] When the RS resource is a semi-persistent RS resource, the start time for the RS resource of the first object to take effect is the first symbol when the MAC CE for activating the semi-persistent RS resource takes effect, and the MAC CE for activating the semi-persistent RS resource takes effect after the first signaling. The end time for the RS resource of the first object to take effect is the first symbol when the MAC CE for deactivating the semi-persistent RS resource takes effect, and the MAC CE for deactivating the semi-persistent RS resource takes effect after the first signaling.

[0133] When the RS resource is an aperiodic RS resource, the start time for the RS resource of the first object to take effect is the last symbol of the physical downlink control channel (PDCCH) that activates the aperiodic RS resource, which is after the first signaling. The end time for the RS resource of the first object to take effect is the last symbol of the physical uplink shared channel (PUSCH) carrying the CSI report triggered by the PDCCH.

[0134] Method 2:

[0135] The target signaling also includes a second signaling, which carries indication information of the first object, and the indication information of the first object is used to indicate the index of the first object.

[0136] Specifically, the target signaling includes first signaling and second signaling. The index of the first object can be the index of the first object among multiple objects, or it can be an absolute object identifier.

[0137] Optionally, in step 301 above, the terminal determines the reference signal RS resource of the first object based on the target signaling, including:

[0138] The terminal determines the first object from multiple objects based on the first signaling and the second signaling;

[0139] The terminal determines the RS resource of the first object based on the configuration information of the RS resources of multiple objects.

[0140] Specifically, the terminal obtains the index of the first object based on the second signaling, and uses the index to search for the first object from the multiple objects included in the first signaling, thereby determining the first object. The terminal determines the RS resource of the first object based on the configuration information of the RS resource of the first object included in the first signaling. That is, the terminal can determine the RS resource of the first object based on the first signaling and the second signaling.

[0141] In practice, the MAC CE or DCI in the second signaling indicates the index of the first object to the terminal in advance. After the terminal successfully receives the MAC CE or DCI, the CSI-RS for CSI and TRS of the first object immediately take effect. The terminal can obtain the accurate time and frequency synchronization information of the first object through the TRS of the first object, and can obtain the CSI report through the CSI-RS of the first object and report it to the current service object or the first object.

[0142] Optionally, the method of this embodiment further includes: the terminal determining the start and end time of the RS resource of the first object taking effect according to a second preset rule; the second preset rule includes: the RS resource of the first object takes effect after the second signaling takes effect and becomes invalid after the fourth signaling takes effect; wherein, the fourth signaling is a signaling to release the RS resource configuration in the first object or a fifth signaling, and the fifth signaling is a second signaling whose start symbol is later than the start symbol of the currently effective second signaling.

[0143] The fifth signaling is a signaling whose start symbol is later than the currently active second signaling, for example, the fifth signaling is the next second signaling.

[0144] Specifically, when the RS resource is a periodic RS resource, the start time of the RS resource activation of the first object is the first symbol after the second signaling takes effect, and the end time of the RS resource activation of the first object is the time when the terminal receives the radio resource control signaling containing the configuration information of releasing the RS resource or the first symbol of the next second signaling takes effect.

[0145] When the RS resource is a semi-persistent RS resource, the start time of the RS resource activation of the first object is the first symbol of the MAC CE that activates the semi-persistent RS resource, and the MAC CE that activates the semi-persistent RS resource is after the second signaling. The end time of the RS resource activation of the first object is the first symbol of the MAC CE that deactivates the semi-persistent RS resource, and the MAC CE that deactivates the semi-persistent RS resource is after the second signaling.

[0146] When the RS resource is an aperiodic RS resource, the start time for the RS resource of the first object to take effect is the last symbol of the PDCCH that activates the aperiodic RS resource, which is after the second signaling. The end time for the RS resource of the first object to take effect is the last symbol of the Physical Uplink Shared Channel (PUSCH) carrying the CSI report triggered by the PDCCH.

[0147] Method 3:

[0148] The target signaling also includes a second signaling for activating at least one aperiodic RS resource, the at least one aperiodic RS resource including at least one target aperiodic RS resource, and the at least one target aperiodic RS resource associated with at least one of a plurality of objects.

[0149] Specifically, the target signaling includes a first signaling and a second signaling. In this embodiment, the second signaling is used to activate at least one aperiodic RS resource. The at least one aperiodic RS resource includes the target aperiodic RS resource of at least one of the multiple objects.

[0150] Optionally, in step 301 above, the terminal determines the reference signal RS resource of the first object based on the target signaling, including:

[0151] The terminal identifies at least one object associated with the non-periodic RS resource activated by the second signaling as the first object;

[0152] The terminal identifies the target aperiodic RS resource associated with at least one object activated by the second signaling as the RS resource of the first object.

[0153] Specifically, since the second signaling is used to activate at least one aperiodic RS resource, the at least one aperiodic RS resource includes at least one target aperiodic RS resource, and the at least one target aperiodic RS resource is associated with at least one of multiple objects, the terminal determines the at least one object associated with the aperiodic RS resource activated by the second signaling as the first object, and determines the target aperiodic RS resource associated with the at least one object activated by the second signaling as the RS resource of the first object, that is, the terminal can determine the RS resource of the first object based on the second signaling.

[0154] In the above implementation, before cell handover, the network-side device triggers the measurement of the aperiodic RS of the first object through MAC CE or DCI in the second signaling. When the terminal successfully receives MAC CE or DCI, the aperiodic RS resource of the first object indicated in MAC CE or DCI becomes effective, and the terminal can perform time-frequency fine synchronization and CSI measurement according to the effective RS.

[0155] Optionally, the method of this embodiment further includes: the terminal determining the start and end times of the RS resource activation of the first object according to a third preset rule; the third preset rule includes: the start time of the RS resource activation of the first object is the last symbol of the second signaling, and the end time of the RS resource activation of the first object is the last symbol of the non-periodic RS resource activated by the second signaling.

[0156] Method 4:

[0157] The target signaling also includes a second signaling, which is used to activate at least one aperiodic CSI report, the at least one aperiodic CSI report being associated with at least one RS resource, and the at least one RS resource being associated with at least one of a plurality of objects.

[0158] Specifically, the target signaling includes a first signaling and a second signaling. In this embodiment, the second signaling is used to activate at least one aperiodic CSI report. The at least one aperiodic CSI report is associated with the RS resource of at least one of the multiple objects.

[0159] Optionally, in step 301 above, the terminal determines the reference signal RS resource of the first object based on the target signaling, including:

[0160] The terminal identifies at least one object associated with an RS resource that is associated with at least one non-periodic CSI report activated by the second signaling as the first object;

[0161] The terminal identifies the RS resource associated with at least one object activated by the second signaling as the RS resource of the first object.

[0162] Specifically, since the second signaling is used to activate at least one non-periodic CSI report, at least one non-periodic CSI report is associated with at least one RS resource, and at least one RS resource is associated with at least one of multiple objects, the terminal determines at least one object associated with the RS resource associated with the at least one non-periodic CSI report activated by the second signaling as the first object, and determines the RS resource associated with at least one object activated by the second signaling as the RS resource of the first object. That is, the terminal can determine the RS resource of the first object based on the second signaling.

[0163] In practice, before cell handover, the network-side equipment triggers CSI reporting via DCI in the second signaling. The CSI reporting is associated with at least one RS resource of the first object. When the terminal successfully receives MAC CE or DCI, MAC CE or DCI indicates that the RS associated with the first object in the CSI reporting is effective. The terminal can perform time-frequency fine synchronization and CSI measurement based on the effective RS.

[0164] Optionally, the method of this embodiment further includes: the terminal determining the start and end times of the RS resource activation of the first object according to a fourth preset rule; the fourth preset rule includes: the start time of the RS resource activation of the first object is the last symbol of the second signaling, and the end time of the RS resource activation of the first object is the last symbol of the uplink channel resource carrying at least one non-periodic CSI report activated by the second signaling.

[0165] Method 5:

[0166] The target signaling also includes third signaling, which carries at least one of the following: indication information for the first object, indication information for RS resources, and indication information for CSI report configuration. The indication information for the first object is used to indicate the index of the first object, the indication information for RS resources is used to indicate at least one RS resource of the first object, and the indication information for CSI report configuration is used to indicate at least one CSI report associated with the RS resource of the first object.

[0167] Specifically, the target signaling includes first signaling and third signaling. The index of the first object can be an index of the first object among multiple objects, or it can be an absolute object identifier. At least one CSI report is associated with the RS resource of at least one of the multiple objects.

[0168] Optionally, in step 301 above, the terminal determines the reference signal RS resource of the first object based on the target signaling, including:

[0169] The terminal determines the first object from among multiple objects based on the indication information of the first object;

[0170] The terminal determines the RS resource of the first object based on the RS resource indication information and / or the indication information configured in the CSI report.

[0171] Specifically, the terminal obtains the index of the first object based on the third signaling, and uses the index to search for the first object from among the multiple objects included in the first signaling, thereby determining the first object. The terminal determines at least one RS resource of the first object indicated by the RS resource indication information as the RS resource of the first object, and / or, the terminal determines the RS resource of at least one of the multiple objects associated with at least one CSI report as the RS resource of the first object. That is, the terminal can determine the RS resource of the first object based on the first signaling and the third signaling.

[0172] In practice, while instructing cell handover, the network-side equipment simultaneously triggers the measurement of the aperiodic RS of the first object via a third instruction, or triggers the aperiodic CSI reporting of the first object via DCI. When the handover instruction takes effect, the aperiodic RS resources of the first object indicated in the handover signaling become effective, or the RS associated with the first object in the CSI reporting indicated in the handover signaling becomes effective. The terminal can then perform time-frequency fine synchronization and CSI measurement based on the effective RS.

[0173] Optionally, the method of this embodiment further includes: the terminal determining the start and end times of the RS resource activation of the first object according to a fifth preset rule; the fifth preset rule includes: the start time of the RS resource activation of the first object is the last symbol of the third signaling or the first symbol after the third signaling takes effect, and the end time of the RS resource activation of the first object is the last symbol of the RS resource indicated by the third signaling or the last symbol of the uplink channel resource carrying the CSI report indicated by the third signaling.

Similarly, the terminal performs CSI measurement and reporting of the RS resources of the first object according to the CPU occupancy criteria, which can reasonably configure the amount and / or time of CPU occupancy, further improving the efficiency of CSI measurement and reporting.

The SSB resources are the SSB resources associated with the first object or the currently serving object.

[0180] The terminal does not receive and / or measure the RS resources of the first object that overlap with the RS resources of the currently served object in the time domain;

[0181] In the time domain of the first target resource, the terminal does not listen to the downlink transmission of the currently serving object. The downlink transmission includes the Physical Downlink Control Channel (PDCCH), the Physical Downlink Shared Channel (PDSCH), and the reference signal. The first symbol of the first target resource differs from the first symbol of the RS resource of the first object by X1 symbols, and the last symbol of the first target resource differs from the last symbol of the RS resource of the first object by Y1 symbols, where X1 and Y1 are both positive integers. Optionally, the values ​​of X1 and Y1 are determined based on factors such as the downlink timing difference and SCS between the first object and the currently serving object. The time domain resource unit can be any of the following: symbol, time slot, frame, nanosecond (ns), microsecond (us), millisecond (ms), or second (s).

[0182] In the time domain of the second target resource, the terminal does not perform uplink transmission of the current serving object.

The unit of time domain resource can be any of the following: symbol, time slot, frame, nanosecond (ns), microsecond (us), millisecond (ms), or second (s).

[0183] In this embodiment, for the pre-activated CSI measurement and reporting of RS resources for the first object, the terminal executes according to measurement and scheduling constraint criteria to avoid conflicts with the measurement and transmission of the current service object, thereby improving the effectiveness of measurement and scheduling.
