Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission methods and apparatus for mobility. Background Technology

[0002] Traditional network-controlled mobility includes cell-level mobility and beam-level mobility. Cell-level mobility relies on RRC (Radio Resource Control) signaling, while beam-level mobility does not involve RRC signaling. Prior to 3GPP (3rd Generation Partnership Project) Release 16, beam-level mobility only addressed beam management within a single cell. The 3GPP RAN#80 meeting decided to launch the "Furtherrenhancements on MIMO for NR" work project (WorkIterm, WI), supporting multi-beam operation and enhancing L1 / L2-centric inter-cell mobility and multiple Transmit / Receive Point (mTRP) inter-cell mobility. Summary of the Invention

[0003] To achieve inter-cell L1 / L2 mobility or inter-cell mTRP, when a UE (User Equipment) is in the serving cell, the network configures the radio parameters of another cell for the UE via RRC messages. Within the coverage area of ​​the serving cell, the UE can use the TRP of the other cell for data transmission. This other cell and the serving cell have different PCIs (Physical Cell Identifiers). The inventors discovered that the existing configuration of reference signal resources for Radio Link Failure (RLF) measurement may need to be redesigned. This application provides a solution to address this problem. While the initial focus was on L1 / L2 mobility or mTRP, this application is also applicable to scenarios such as Layer 3 handover or sidelinks, achieving similar technical effects. Furthermore, using a unified solution across different scenarios helps reduce hardware complexity and cost.

[0004] It should be noted that, unless otherwise specified, the embodiments and features in any node of this application can be applied to any other node. Furthermore, unless otherwise specified, the embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

[0005] As an example, the interpretation of the terminology in this application is based on the definitions in the 3GPP specification protocol TS38 series.

[0006] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS36 series.

[0007] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS37 series.

[0008] As an example, the interpretation of terms in this application is based on the definitions in the IEEE (Institute of Electrical and Electronics Engineers) specification protocols.

[0009] This application discloses a first node used for wireless communication, characterized in that it includes:

[0010] A first receiver receives a first signaling set, the first signaling set including at least one first signaling, the first signaling being used to indicate a candidate TCI (Transmission Configuration Indicator) state set of a first control resource set (CORESET), the candidate TCI state set of the first control resource set including at least one TCI state; and evaluates whether a radio link failure has occurred according to a first RS resource group, the first RS resource group including at least one RS resource.

[0011] Wherein, the active TCI state of the first control resource set is the first TCI state, and the first TCI state is one of the TCI states in the candidate TCI state set of the first control resource set; the first TCI state indicates at least the first RS resource; at least the first signaling is used to determine whether the first RS (Reference Signal) resource belongs to the first RS resource group, and the first node is not configured with RadioLinkMonitoringRS.

[0012] As an example, the first node did not receive signaling specifically for configuring RS resources for RLF measurements.

[0013] As an example, the maximum number of SSB (Synchronization Signal / Physical Broadcast Channel block) indexes on the serving cell of the first node is not less than 8.

[0014] As an example, in a traditional NR (New Radio) system, if the UE is not configured with RadioLinkMonitoringRS and is configured with a TCI state for PDCCH (Physical Downlink Control Channel) reception, whether the RS resources included in the active TCI state of the CORESET are used for RLF measurement depends only on the period of the search space associated with the CORESET in the time domain or the index of the CORESET. In the above method, whether the RS resources included in the active TCI state of the CORESET are used for RLF measurement is related to the signaling of configuring the candidate TCI state set, providing a more flexible possibility of selecting RS resources for RLF measurement and better adapting to the needs in different mobile scenarios.

[0015] This application discloses a method used in a first node for wireless communication, characterized by comprising:

[0016] Receive a first signaling set, the first signaling set including at least a first signaling, the first signaling being used to indicate a candidate TCI state set of a first control resource set, the candidate TCI state set of the first control resource set including at least one TCI state;

[0017] Whether a radio link failure has occurred is assessed based on a first RS resource group, wherein the first RS resource group includes at least one RS resource;

[0018] Wherein, the active TCI state of the first control resource set is the first TCI state, and the first TCI state is one of the TCI states in the candidate TCI state set of the first control resource set; the first TCI state indicates at least the first RS resource; at least the first signaling is used to determine whether the first RS resource belongs to the first RS resource group, and the first node is not configured with RadioLinkMonitoringRS.

[0019] Specifically, according to one aspect of this application, the method used in the first node for wireless communication is characterized in that, the determination of whether the first RS resource belongs to the first RS resource group by at least the first signaling includes: whether the candidate TCI state set of the first control resource set includes RS resources associated with the first PCI is used to determine whether the first RS resource belongs to the first RS resource group.

[0020] As an example, the above method can flexibly determine the RS resources used for RLF measurement based on whether they are associated with the first PCI, thus improving configuration flexibility.

[0021] Specifically, according to one aspect of this application, the method used in the first node for wireless communication is characterized in that if the RS resources included in each TCI state in the candidate TCI state set of the first control resource set are not associated with the first PCI, the first RS resource belongs to the first RS resource group; if the RS resources included in each TCI state in the candidate TCI state set of the first control resource set are associated with the first PCI, the first RS resource does not belong to the first RS resource group.

[0022] As an example, the above method excludes RS resources included only by the active TCI state of the CORESET associated with the first PCI, thus maintaining better compatibility with existing NR systems.

[0023] Specifically, according to one aspect of this application, the method used in the first node of wireless communication is characterized by comprising:

[0024] Receive a second signaling message, the second signaling message including an identifier of the first control resource set and an identifier of a TCI status;

[0026] As an example, the above method associates whether the first RS resource belongs to the first RS resource group with the active TCI status of CORESET, which enables more timely configuration of RS resources for RLF measurement.

[0027] As an example, if the first RS resource is determined to belong to the first RS resource group, the measurement of the first RS resource by the first node device before receiving the second signaling is not included in the behavior of evaluating whether a radio link failure has occurred based on the first RS resource group.

[0028] Specifically, according to one aspect of this application, the method used in the first node for wireless communication is characterized in that whether the first TCI state includes RS resources associated with the first PCI is used to determine whether the first RS resource belongs to the first RS resource group, including: if the first TCI state does not include RS resources associated with the first PCI, the first RS resource belongs to the first RS resource group; if the first TCI state includes RS resources associated with the first PCI, the first RS resource does not belong to the first RS resource group.

[0050] This application discloses a second node used for wireless communication, characterized by comprising:

[0051] A second transmitter transmits a first signaling set, the first signaling set including at least a first signaling, the first signaling being used to indicate a candidate TCI state set of a first control resource set, the candidate TCI state set of the first control resource set including at least one TCI state; a first RS resource group evaluation is used to evaluate whether a radio link failure has occurred, the first RS resource group including at least one RS resource;

[0052] The second receiver receives the third signaling, which is a higher-level signaling.

[0054] As an example, compared with conventional solutions, this application has the following advantages:

[0055] - More flexible configuration of RS resources for RLF measurements;

[0056] - To maintain better compatibility with existing systems.

[0057] This application discloses a first node used for wireless communication, characterized in that it includes:

[0058] The first node used for wireless communication includes:

[0059] A first receiver receives a first signaling instruction, which is used to indicate a first RS (Reference Signal) resource group, the first RS resource group including a first RS resource subgroup and a second RS resource subgroup; each RS resource in the first RS resource subgroup is associated with a first PCI, and each RS resource in the second RS resource subgroup is associated with a second PCI.

[0060] The first receiver evaluates whether a radio link failure (RLF) has occurred based on no more than L1 RS resources and no more than L2 RS resources, wherein the no more than L1 RS resources are a subset of the first RS resource subgroup and the no more than L2 RS resources are a subset of the second RS resource subgroup.

[0061] Wherein, L1 depends on at least the former of the maximum number of SSB indexes of the first cell and the maximum number of SSB (Synchronization Signal / Physical Broadcast CHannel block) indexes of the second cell, and the first cell is identified by the first PCI; L2 depends on at least the latter of the maximum number of SSB indexes of the first cell and the maximum number of SSB indexes of the second cell, and the second cell is identified by the second PCI.

[0062] This application discloses a method used in a first node for wireless communication, characterized by comprising:

[0063] Receive a first signaling, the first signaling being used to indicate a first RS (Reference Signal) resource group, the first RS resource group including a first RS resource subgroup and a second RS resource subgroup; each RS resource in the first RS resource subgroup is associated with a first PCI, and each RS resource in the second RS resource subgroup is associated with a second PCI;

[0064] Whether a radio link failure has occurred is evaluated based on no more than L1 RS resources and no more than L2 RS resources, wherein the no more than L1 RS resources are a subset of the first RS resource subgroup and the no more than L2 RS resources are a subset of the second RS resource subgroup;

[0065] Wherein, L1 depends on at least the former of the maximum number of SSB indexes of the first cell and the maximum number of SSB (Synchronization Signal / Physical Broadcast CHannel block) indexes of the second cell, and the first cell is identified by the first PCI; L2 depends on at least the latter of the maximum number of SSB indexes of the first cell and the maximum number of SSB indexes of the second cell, and the second cell is identified by the second PCI.

[0066] As an example, one advantage of the above method is that it uses RS resources associated with two PCIs to test an RLF.

[0067] As an example, one advantage of the above method is that it avoids sending downlink signaling to explicitly instruct the first node on how to select RS resources associated with each PCI, thus reducing signaling overhead.

[0068] As an example, the second cell is the Spcell (Special Cell) of the first node.

[0076] As an example, determining L3 based on the indication of the first node provides an opportunity to maintain good compatibility with existing systems, such as L1 and L2, which are both compatible with existing systems.

[0078] As an example, the above method ensures that the number of RS resources associated with each PCI is not less than a specific reservation value, thus ensuring the monitoring quality for each cell.

[0079] As an example, both the first reserved value and the second reserved value are positive integers.

[0080] As an example, both the first reserved value and the second reserved value are constants of 1.

[0081] As one embodiment, the first reservation value depends on at least the former of the maximum number of SSB indexes of the first cell and the number of RS resources in the first RS resource group associated with the first PCI; the second reservation value depends on at least the former of the maximum number of SSB indexes of the second cell and the number of RS resources in the first RS resource group associated with the second PCI.

[0084] Wherein, the number of RS resources associated with the first PCI in the first RS resource subgroup is greater than L1, and the number of RS resources associated with the second PCI in the second RS resource subgroup is greater than L2.

[0085] As an example, RS resources are selected in the following order: first, monitoring period from short to long; second, control resource set identifier from high to low.

[0086] As an example, RS resources are selected in the following order: first, monitoring period from short to long; second, RS resource type; and third, RS resource identifier.

[0087] Specifically, according to one aspect of this application, the method used in the first node of wireless communication is characterized by comprising:

[0088] Receive a second signaling message, the second signaling message being used to indicate that at least one RS resource in the first RS resource group is associated with a PCI;

The no more than L1 RS resources are a subset of the first RS resource subgroup, and the no more than L2 RS resources are a subset of the second RS resource subgroup. The L1 depends on at least the former of the maximum number of SSB indexes of the first cell and the maximum number of SSB indexes of the second cell, where the first cell is identified by the first PCI.

[0140] In Example 1A, the active TCI state of the first control resource set is the first TCI state, which is a TCI state in the candidate TCI state set of the first control resource set; the first TCI state indicates at least the first RS resource; at least the first signaling is used to determine whether the first RS resource belongs to the first RS resource group, and the first node is not configured with RadioLinkMonitoringRS.

[0145] As an example, the first signaling includes at least one RRC message.

[0146] As an example, the first signaling includes at least one IE (Information element) in the RRC message.

[0147] As an example, the first signaling includes at least one field from an RRC message.

[0148] As an example, the first signaling set is RRC (Radio Resource Control) layer signaling.

[0149] As an example, the identifier of the first control resource set is 0, the first signaling includes a PDSCH-Config IE (Information Element), and the candidate TCI state set of the first control resource set includes tci-States-ToAddModList in the PDSCH-Config IE.

[0150] As a sub-implementation of the above embodiments, the candidate TCI state set of the first control resource set includes tci-states-ToReleaseList in the PDSCH-Config IE.

[0151] As an example, the identifier of the first control resource set is not 0, and the first signaling includes tci-StatesPDCCH-ToAddList.

[0152] As a sub-implementation of the above embodiments, the first signaling includes tci-StatesPDCCH-ToReleaseList.

[0153] As a sub-implementation of the above embodiments, the first signaling belongs to the controlResourceSet IE used to configure the first control resource set.

[0154] As a sub-implementation of the above embodiments, the first signaling belongs to the controlResourceSet IE used to configure the first control resource set and does not include controlResourceSetId.

[0155] As a sub-implementation of the above embodiments, the identifier of the first control resource set is not 0, and the first signaling only includes tci-StatesPDCCH-ToAddList and tci-StatesPDCCH-ToReleaseList.

[0156] As an example, the candidate TCI state set of the first control resource set includes only one TCI state, and the active TCI state of the first control resource set is the TCI state included in the candidate TCI state set of the first control resource set.

[0157] As an example, the candidate TCI state set of the first control resource set includes only a plurality of TCI states, and the active TCI state of the first control resource set is indicated by a second signaling.

[0158] As an example, the first signaling set includes only at least the first signaling, that is, the first signaling set is the first signaling.

[0159] As an example, the first node is configured to receive at least one TCI state including CSI-RS (Channel Status Information Reference Signal) resources in the TCI state of the PDCCH.

[0160] As an example, the behavior is performed only when the first node is configured to receive PDCCH and at least one TCI state includes CSI-RS resources, the behavior is performed only if a radio link failure is assessed based on the first RS resource group.

[0161] As an example, the aforementioned CSI-RS resources are configured to the BWP (BandWidth Part) to which the first control resource set belongs.

[0162] As an example, the aforementioned CSI-RS resources are configured to the carrier component to which the first control resource set belongs.

[0163] As an example, the action is performed only when the first node is configured to receive PDCCH and at least one TCI state in the TCI state includes a CSI-RS resource associated with a second PCI, which is the PCI of the serving cell of the first node.

[0164] As an example, the aforementioned CSI-RS resources are configured to the BWP (BandWidth Part) to which the first control resource set belongs.

[0165] As an example, the aforementioned CSI-RS resources are configured to the carrier component to which the first control resource set belongs.

[0166] As an example, the first RS resource is a CSI-RS resource.

[0167] As an example, if the first RS resource belongs to the first RS resource group, the first RS resource is used to assess whether a radio link failure has occurred; if the first RS resource does not belong to the first RS resource group, the first RS resource is not used to assess whether a radio link failure has occurred.

[0168] As an example, the first node not being configured with RadioLinkMonitoringRS means that the first node is not configured with RadioLinkMonitoringRS on the BWP (BandWidth Part) to which the first control resource set belongs.

[0169] As an example, the first node not being configured with RadioLinkMonitoringRS means that the first node is not configured with RadioLinkMonitoringRS on the carrier component to which the first control resource set belongs.

[0170] As an example, "the first node is not configured with RadioLinkMonitoringRS" means that the first node is not configured with RadioLinkMonitoringRS on the serving cell to which the first control resource set belongs.

[0171] As an example, the first control resource set and the first RS resource are on the same BWP.

[0172] As an example, the first control resource set and any RS resource in the first RS resource group are on the same BWP.

[0173] As an example, the first TCI state only includes the first RS resource.

[0174] As an example, the first RS resource is the RS resource whose qcl-type is configured as typeD among the RS resources included in the first TCI state.

[0175] As one embodiment, the first TCI state includes only the first RS resource; or, the first TCI state includes two RS resources, wherein the first RS resource is the RS resource whose qcl-type is configured as typeD.

[0176] As an example, the active TCI state of the first control resource set refers to the TCI state currently applied to the first control resource set.

[0177] As an example, any RS resource in the first RS resource group is a CSI-RS resource or an SSB indicated by an ssb-Index.

[0178] As an example, any RS resource in the first RS resource group is a CSI-RS resource.

[0179] As one embodiment, the first signaling set is transmitted via the UU interface.

[0180] As an example, the first signaling set is transmitted via PC5 port.

[0181] As an example, the step of assessing whether a wireless link failure has occurred based on a first RS resource group includes: assessing whether out-of-sync has occurred based on at least a portion of the RS resources in the first RS resource group; if out-of-sync has occurred, the physical layer of the first node 100 indicates out-of-sync to a higher layer of the first node 100.

[0182] As an example, the step of assessing whether a wireless link failure has occurred based on a first RS resource group includes: assessing whether synchronization is maintained based on at least a portion of the RS resources in the first RS resource group; if synchronization is maintained, the physical layer of the first node 100 indicates in-sync to a higher layer of the first node 100.

[0183] As an example, if the radio link quality of each RS resource in at least a portion of the RS resources in the first RS resource group is worse than a first threshold, the evaluation is out of sync; if the radio link quality of any RS resource in at least a portion of the RS resources in the first RS resource group is better than a second threshold, the evaluation remains synchronized; the first threshold and the second threshold are both configurable.

[0184] As an example, the first threshold and the second threshold are Qout and Qin, respectively.

[0185] As an example, the at least some RS resources in the first RS resource group are all RS resources in the first RS resource group.

[0186] As an example, the higher layer of the first node 100 receiving Q1 consecutive out-of-sync indications is used to trigger the start of a first timer, the expiration of which is used to determine that the wireless link failure has occurred, and the Q1 is configurable.

[0187] As an example, Q1 is N310, and the first timer is T310.

[0188] As one embodiment, the higher layer of the first node 100 receiving Q2 consecutive in-sync indications is used to trigger the stopping of a first timer, the expiration of which is used to determine that the wireless link failure has occurred, and the Q2 is configurable.

[0189] As an example, Q2 is N311, and the first timer is T310.

[0190] As an example, the wireless link quality includes: RSRP (Reference Signal Received Power) measurement results.

[0191] As an example, the wireless link quality includes: RSRQ (Reference Signal Received Quality) measurement results.

[0192] As an example, the wireless link quality includes: BLER (Block Error Ratio).

[0193] As an example, each indication period is used to evaluate whether a loss of synchronization has occurred and whether synchronization has been maintained, based on at least some of the RS resources in the first RS resource group.

[0194] As an example, the reporting period does not exceed 10 milliseconds.

[0195] As an example, the reporting period is the maximum value between the shortest period of the first RS resource group and 10 milliseconds.

[0196] Example 1B

[0197] Example 1B illustrates an embodiment of the present application for evaluating whether an RLF has occurred, as shown in the appendix. Figure 1B As shown. (Attached) Figure 1B In the diagram, each box represents a step.

[0198] In Embodiment 1B, in step 101a, the first node 100a receives a first signaling, which is used to indicate a first RS resource group, the first RS resource group including a first RS resource subgroup and a second RS resource subgroup; each RS resource in the first RS resource subgroup is associated with a first PCI, and each RS resource in the second RS resource subgroup is associated with a second PCI; in step 102a, a radio link failure is evaluated based on no more than L1 RS resources and no more than L2 RS resources, wherein the no more than L1 RS resources are a subset of the first RS resource subgroup, and the no more than L2 RS resources are a subset of the second RS resource subgroup;

[0199] In Example 1B, L1 depends on at least the former of the maximum number of SSB indexes of the first cell and the maximum number of SSB indexes of the second cell, and the first cell is identified by the first PCI; L2 depends on at least the latter of the maximum number of SSB indexes of the first cell and the maximum number of SSB indexes of the second cell, and the second cell is identified by the second PCI.

[0200] As an example, the first RS resource subgroup and the second RS resource subgroup each include at least one RS resource.

[0201] As an example, the first signaling is higher-layer signaling.

[0202] As an example, the first signaling includes a downlink (DL) signaling.

[0203] As an example, the first signaling includes a sidelink (SL) signaling.

[0204] As an example, the first signaling includes at least one RRC message.

[0205] As an example, the first signaling includes at least one IE (Information Element) at the RRC layer.

[0206] As an example, the first signaling set is RRC (Radio Resource Control) layer signaling.

[0207] As one embodiment, the first signaling includes a RadioLinkMonitoringConfig IE (Information Element).

[0208] As a sub-example of the above embodiments, each RS resource in the first RS resource group is configured by a RadioLinkMonitoringRS IE.

[0209] As an example, the first node 100 is not configured with RadioLinkMonitoringRS, and the first signaling includes at least one TCI (Transmission Configuration Indicator) state used to configure PDCCH reception.

[0210] As a sub-example of the above embodiment, if the active TCI state for PDCCH reception includes only one RS resource, the RS resource belongs to the first RS resource group.

[0211] As a sub-example of the above embodiment, if the active TCI state for PDCCH reception includes only two RS resources, the RS resource in which qcl-type is set to typeD belongs to the first RS resource group.

[0212] As an example, the first signaling includes a PDSCH-Config IE (Information Element), and among the active TCI states for PDCCH reception, there is an active TCI state that belongs to a TCI-state in the tci-States-ToAddModList or tci-States-ToReleaseList of the PDSCH-Config IE.

[0213] As an example, the first signaling includes at least one tci-StatesPDCCH-ToAddList, each of the at least one tci-StatesPDCCH-ToAddList including one of the active TCI states.

[0214] As an example, the first signaling includes at least one tci-StatesPDCCH-ToReleaseList, each of the at least one tci-StatesPDCCH-ToReleaseList including one of the active TCI states.

[0215] As an example, for at least one CORESET (Control Resource Set), the second signaling is used to indicate the active TCI state for PDCCH reception from the tci-StatesPDCCH-ToAddList and / or tci-StatesPDCCH-ToReleaseList of the corresponding CORESET.

[0216] As an example, the second signaling is a MAC CE (TCI State Indication for UE-specific PDCCH MAC CE) that indicates the TCI state of the UE-specific PDCCH.

[0217] As an example, the second signaling is a DCI (Downlink Control Information).

[0218] As an example, each RS resource in the first RS resource group is a CSI-RS (Channel Status Information Reference Signal) resource or an SSB indicated by an ssb-index.

[0219] As an example, each RS resource in the first RS resource group is included by a TCI state.

[0220] As an example, the behavior is performed only when the first node is configured to receive PDCCH and at least one TCI state includes CSI-RS resources, the behavior is performed only after evaluating whether a radio link failure has occurred based on no more than L1 RS resources and no more than L2 RS resources.

[0221] As an example, the behavior is performed on the active downlink BWP (BandWidth Part) based on an assessment of whether a radio link failure has occurred, based on no more than L1 RS resources and no more than L2 RS resources.

[0222] As an example, each RS resource in the first RS resource group is configured to the active downlink BWP (BandWidth Part).

[0223] As an example, each RS resource in the first RS resource group is configured to the same carrier component.

[0224] As an example, any RS resource in the first RS resource group is a CSI-RS resource or an SSB indicated by an ssb-Index.

[0225] As an example, any RS resource in the first RS resource group is a CSI-RS resource.

[0226] As one embodiment, the first signaling set is transmitted via the UU interface.

[0227] As an example, the first signaling set is transmitted via PC5 port.

[0228] As an example, neither L1 nor L2 is greater than 8.

[0229] As an example, the sum of L1 and L2 is not greater than 12.

[0230] As an example, the number of RS resources in the first RS resource subgroup is greater than that of L1.

[0231] As an example, the number of RS resources in the second RS resource subgroup is greater than that in L2.

[0232] As an example, the maximum number of SSB indices of the first cell is related to the subcarrier spacing of the SSBs of the first cell, and the maximum number of SSB indices of the second cell is related to the subcarrier spacing of the SSBs of the second cell.

[0233] As an example, the maximum number of SSB indexes in the first cell is one of 4, 8, or 64, and the maximum number of SSB indexes in the second cell is one of 4, 8, or 64.

[0234] As an example, the maximum number of SSB indexes of the first cell is Lmax of the first cell, and the maximum number of SSB indexes of the second cell is Lmax of the second cell.

[0235] As an example, L1 depends only on the maximum number of SSB indexes of the first cell, and L2 depends only on the maximum number of SSB indexes of the second cell.

[0236] As a sub-example of the above embodiment, L1 and L2 are determined by looking up tables.

[0237] As a sub-implementation of the above embodiments, the maximum number of SSB indexes of the first cell is 4, 8 or 64, and the corresponding L1 is 2, 4 or 8 respectively; the maximum number of SSB indexes of the second cell is 4, 8 or 64, and the corresponding L2 is 2, 4 or 8 respectively.

[0238] As a sub-implementation of the above embodiments, based on the assumption that the first RS resource group only includes RS resources associated with the first PCI, L1 is the maximum number of RS resources used to assess whether a radio link failure has occurred; based on the assumption that the first RS resource group only includes RS resources associated with the second PCI, L2 is the maximum number of RS resources used to assess whether a radio link failure has occurred.

[0239] As an example, the L1 depends on the maximum number of SSB indexes of the first cell and the maximum number of SSB indexes of the second cell.

[0240] As an example, the L2 depends on the maximum number of SSB indexes of the first cell and the maximum number of SSB indexes of the second cell.

[0241] As an example, L1 and L2 are:

[0242] Table 1

[0243]

[0244] In Table 1, I1, I2, I3, ..., I9 and J1, J2, J3, ..., J9 are all fixed constants.

[0245] As an example, the maximum value among I1, I2, I3, ..., I9 and J1, J2, J3, ..., J9 is 8, and the minimum value among I1, I2, I3, ..., I9 and J1, J2, J3, ..., J9 is 2.

[0246] As an example of Table 1, L1 and L2 are:

[0247] Table 2

[0248]

[0249] As an example, the number of RS resources used to assess whether a wireless link failure has occurred does not exceed L3; L3 is not greater than the sum of L1 and L2.

[0250] As an example, the total number of RS resources included in the no more than L1 RS resources and the no more than L2 RS resources does not exceed L3; L3 is not greater than the sum of L1 and L2.

[0251] As an example, L3 is less than the sum of L1 and L2.

[0252] As an example, L3 is the larger of L1 and L2.

[0253] As an example, L3 is the sum of L1 and L2.

[0254] As an example, the L3 depends on the maximum number of SSB indexes of the first cell and the maximum number of SSB indexes of the second cell.

[0255] As an example, L3 is:

[0256] Table 3

[0257]

[0258] As an example, K1 is 4 and K6 is 8.

[0259] As an example of Table 3, L3 is:

[0260] Table 3

[0261]

[0262] As an example of Table 3, L3 is:

[0263] Table 3

[0264]

[0265] As an example, when the difference between L3 and L4 is less than L1, the number of RS resources included in the no more than L1 RS resources does not exceed the difference between L3 and L4; L4 is the number of RS resources included in the no more than L2 RS resources; L4 does not exceed L2.

[0266] The above embodiments can preferentially meet the requirements for RLF measurement of the second cell.

[0267] As one embodiment of the above embodiments, only the second cell is the Spcell of the first node.

[0268] As one embodiment of the above embodiments, the maximum number of SSB indexes of the first cell is less than the maximum number of SSB indexes of the second cell.

[0269] As one embodiment of the above embodiments, only the second cell can be indicated by the CI (Carrier Indicator) field in the DCI (Downlink Control Information) received by the first node 100.

[0270] As one embodiment of the above embodiments, only the second cell is configured as a serving cell of the first node 100.

[0271] As an example, the step of evaluating whether a radio link failure has occurred based on no more than L1 RS resources and no more than L2 RS resources includes: evaluating whether out-of-sync has occurred based on the no more than L1 RS resources and no more than L2 RS resources; if out-of-sync has occurred, the physical layer of the first node 100 indicates out-of-sync to the higher layer of the first node 100.

[0272] As an example, the step of evaluating whether a radio link failure has occurred based on the no more than L1 RS resources and the no more than L2 RS resources includes: evaluating whether synchronization is maintained based on the no more than L1 RS resources and the no more than L2 RS resources; if synchronization is maintained, the physical layer of the first node 100 indicates in-sync to the higher layer of the first node 100.

[0273] As an example, if the radio link quality of each of the no more than L1 RS resources and the no more than L2 RS resources is worse than a first threshold, the evaluation is out of sync; if the radio link quality of one of the no more than L1 RS resources and the no more than L2 RS resources is better than a second threshold, the evaluation remains synchronized; the first threshold and the second threshold are both configurable.

[0274] As an example, the first threshold and the second threshold are Qout and Qin, respectively.

[0275] As an example, the no more than L1 RS resources and the no more than L2 RS resources include all RS resources in the first RS resource group.

[0276] As an example, the no more than L1 RS resources and the no more than L2 RS resources are proper subsets of the first RS resource group.

[0277] As an example, the higher layer of the first node 100 receiving Q1 consecutive out-of-sync indications is used to trigger the start of a first timer, the expiration of which is used to determine that the wireless link failure has occurred, and the Q1 is configurable.

[0278] As an example, Q1 is N310, and the first timer is T310.

[0279] As one embodiment, the higher layer of the first node 100 receiving Q2 consecutive in-sync indications is used to trigger the stopping of a first timer, the expiration of which is used to determine that the wireless link failure has occurred, and the Q2 is configurable.

[0280] As an example, Q2 is N311, and the first timer is T310.

[0281] As an example, the wireless link quality includes: RSRP (Reference Signal Received Power) measurement results.

[0282] As an example, the wireless link quality includes: RSRQ (Reference Signal Received Quality) measurement results.

[0283] As an example, the wireless link quality includes: BLER (Block Error Ratio).

[0284] As an example, each indication period is used to evaluate whether a loss of synchronization has occurred and whether synchronization has been maintained, based on no more than L1 RS resources and no more than L2 RS resources.

[0285] As an example, the number of RS resources not exceeding L1 and the number of RS resources not exceeding L2 are variable for different reporting periods.

[0286] As an example, the reporting period does not exceed 10 milliseconds.

[0287] As an example, the reporting period is the maximum value between the shortest period of the first RS resource group and 10 milliseconds.

The MME / AMF / SMF211 is the control node that handles signaling between UE201 and 5GC / EPC210. ​​Essentially, the MME / AMF / SMF211 provides bearer and connection management. All user IP (Internet Protocol) packets are transmitted through the S-GW / UPF212, which is itself connected to the P-GW / UPF213. The P-GW provides UE IP address allocation and other functions.

[0341] Example 3

[0342] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3 The radio protocol architecture for control plane 300 is illustrated using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and cross-area mobility support. The RLC sublayer 303 provides segmentation and reassembly of upper-layer packets, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and using RRC signaling to configure the lower layers. The radio protocol architecture of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture in the user plane 350 is largely the same as the corresponding layers and sublayers in the control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2 Layer 355, RLC sublayer 353 in L2 Layer 355, and MAC sublayer 352 in L2 Layer 355. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also includes the SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for mapping between QoS streams and data radio bearers (DRBs) to support service diversity. Generally speaking, a layer above L1 is referred to as a higher layer.

[0351] Example 4

[0352] Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in the access network.

[0353] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0354] The second communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0355] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0356] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the first communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover upper-layer data and control signals transmitted by the second communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements L2 layer functions. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In transmissions from the second communication device 410 to the first communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above L2. Various control signals may also be provided to L3 for L3 processing.

[0357] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0358] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer data packets from the controller / processor 475 can be provided to the core network.

[0388] As one embodiment, the use of at least the first signaling to determine whether the first RS resource belongs to the first RS resource group includes: a first field in the first signaling explicitly indicating whether the first RS resource belongs to the first RS resource group.

[0398] As an example, the identifier of a TCI state is TCI-StateId.

[0399] As an example, the PCI of the Spcell (Special Cell) of the first node U01 is the second PCI, which is different from the first PCI.

[0400] As an example, the cell with the second PCI identifier is configured as the serving cell of the first node U01, while the cell with the first PCI identifier is not configured as the serving cell of the first node U01.

[0401] As one embodiment, the cell identified by the second PCI is configured to the first node U01 by SpCellConfig signaling or SCellConfig signaling, and the cell identified by the first PCI is configured to the first node U01 by RRC signaling other than SpCellConfig signaling and SCellConfig signaling.

[0402] As one example, the second node N02 maintains the serving cell of the second PCI identifier.

[0403] As an example, the second node N02 maintains the cell with the first PCI identifier and the serving cell with the second PCI identifier.

[0404] As an example, when an RS resource is allocated to a cell indicated by a PCI, the RS resource is associated with the PCI.

[0405] As an example, when a PCI is used to generate an RS sequence of an RS resource, the RS resource is associated with the PCI.

[0406] As an example, when an RS resource is associated with an SSB QCL (Quasi co-location) indicated by an ssb-Index of a cell indicated by a PCI, the RS resource is associated with the PCI.

[0407] As an example, when an RS resource is synchronized with the cell downlink indicated by a PCI, the RS resource is associated with the PCI.

[0408] As an example, when an RS resource is transmitted on a cell indicated by a PCI, the RS resource is associated with the PCI.

[0409] As an example, when an RS resource is an SSB indicated by an ssb-Index of a cell indicated by a PCI, the RS resource is associated with the PCI.

[0410] As an example, the type of an RS resource is either an SSB indicated by ssb-Index or a CSI-RS resource.

[0411] As an example, the CSI-RS resource is a periodic CSI-RS resource.

[0412] As an example, an RS resource can be one of the following: SSB indicated by ssb-Index, CSI-RS resource, CSI-IM (Interference Measurement) resource, DMRS (Demodulation Reference Signal) resource, or CRS (Cell Reference Signal) resource.

[0413] As an example, any two RS resources in the first RS resource group are of the same type.

[0414] As an example, at least two RS resources in the first RS resource group are of different types.

[0415] As an example, the first PCI and the second PCI are two different TRPs.

[0418] for First node U01In step S5101a, a first signaling is received, which is used to indicate a first RS resource group, the first RS resource group including a first RS resource subgroup and a second RS resource subgroup; each RS resource in the first RS resource subgroup is associated with a first PCI, and each RS resource in the second RS resource subgroup is associated with a second PCI; in step S5102a, a second signaling is received, which is used to indicate the PCI to which at least one RS resource in the first RS resource group is associated; in step S5103a, whether a radio link failure has occurred is evaluated based on no more than L1 RS resources and no more than L2 RS resources, wherein the no more than L1 RS resources are a subset of the first RS resource subgroup, and the no more than L2 RS resources are a subset of the second RS resource subgroup;

[0419] for Second node N02 In step S5201a, the first signaling is sent; in step S5202a, the second signaling is sent.

[0420] In Example 5B, L1 depends on at least the former of the maximum number of SSB indices of the first cell and the maximum number of SSB indices of the second cell, the first cell being identified by the first PCI; L2 depends on at least the latter of the maximum number of SSB indices of the first cell and the maximum number of SSB indices of the second cell, the second cell being identified by the second PCI; the action receives the second signaling before the action evaluates whether a radio link failure has occurred based on no more than L1 RS resources and no more than L2 RS resources; the PCI associated with at least one RS resource in the first RS resource group is one of the first PCI and the second PCI.

[0421] As an example, the first signaling is an RRC layer message, and the second signaling is a protocol layer message below the RRC layer.

[0422] As an example, the first node U01 sends a first message in step S5100a; the second node U02 receives the first message in step S5200a; wherein the number of RS resources used to assess whether a wireless link failure has occurred does not exceed L3; the first message indicates L3.

[0423] As an example, the second node U02 determines, based on the first message, the number of RS resources included in the first RS resource group, the number of RS resources in the first RS resource group that are associated with the first PCI, or the number of RS resources in the first RS resource group that are associated with the second PCI.

[0424] As an example, the first message is a higher-level message.

[0425] As an example, the first message is an RRC layer message.

[0426] As one example, the first message includes UE capability-related information.

[0427] As an example, the first message is the UECapabilityInformation IE.

[0428] As an example, the number of RS resources used to assess whether a radio link failure has occurred does not exceed L3; L3 is less than the sum of L1 and L2, and L3 depends on the maximum number of SSB indices of the first cell and the maximum number of SSB indices of the second cell.

[0429] As an example, the first signaling is RRC layer signaling, and the second signaling is MAC CE (Control Element).

[0430] In traditional schemes, the configuration of RLF measurements is achieved through RRC layer signaling. However, the above method, which combines MAC CE with RRC signaling, allows for more flexible configuration of RS resources.

[0431] As an example, the PCI indicated by the second signaling is the PCI to which the RS resource included in the TCI state indicated by the second signaling is associated.

[0432] As an example, the second signaling is a MAC CE (TCIState Indication for UE-specific PDCCH MAC CE) that indicates the TCI state of the UE-specific PDCCH.

[0433] As an example, L3 is equal to the sum of L1 and L2; L1 depends on the maximum number of SSB indexes of the first cell and the maximum number of SSB indexes of the second cell; L2 depends on the maximum number of SSB indexes of the first cell and the maximum number of SSB indexes of the second cell.

[0434] As an example, L3 is less than the sum of L1 and L2; L1 depends only on the maximum number of SSB indexes of the first cell; and L2 depends only on the maximum number of SSB indexes of the second cell.

[0435] As an example, the number of RS resources included in the no more than L1 RS resources is not less than the first reserved value.

[0436] As a sub-implementation of the above embodiments, the first reserved value is configurable.

[0437] As a sub-example of the above embodiments, the candidate values ​​of the first reserved value include 0.

[0438] As a sub-example of the above embodiment, the number of RS resources included in the no more than L2 RS resources is not less than the second reserved value.

[0439] As an example, both the first reserved value and the second reserved value are positive integers.

[0440] As an example, both the first reserved value and the second reserved value are constants of 1.

[0441] As an example, the first reservation value depends on at least the former of the maximum number of SSB indexes of the first cell and the number of RS resources in the first RS resource group associated with the first PCI.

[0442] As an example, the first reserved value depends on the maximum number of SSB indices of the first cell.

[0443] As a sub-example of the above embodiment, the first reserved value increases as the maximum number of SSB indexes of the first cell increases.

[0444] As a sub-example of the above embodiment, when the maximum number of SSB indexes of the first cell is 4, 8 or 64, the first reserved values ​​are 1, 1 and 2 respectively.

[0445] As a sub-example of the above embodiment, when the maximum number of SSB indexes of the first cell is 4, 8 or 64, the first reserved values ​​are 0, 0 and 1 respectively.

[0446] As a sub-example of the above embodiment, when the maximum number of SSB indexes of the first cell is 4, 8 or 64, the first reserved values ​​are 0, 1 and 2 respectively.

[0447] As an example, the first reservation value depends on the maximum number of SSB indexes of the first cell and the number of RS resources in the first RS resource group that are associated with the first PCI.

[0448] As a sub-implementation of the above embodiments, the second reserved value is the smaller of the first reference value and the number of RS resources in the first RS resource group associated with the second PCI, wherein the first reference value depends on the maximum number of SSB indexes of the first cell.

[0449] As a sub-example of the above embodiment, when the maximum number of SSB indexes of the first cell is 4, 8 or 64, the first reference values ​​are 1, 1 and 2 respectively.

[0450] As a sub-example of the above embodiment, when the maximum number of SSB indexes of the first cell is 4, 8 or 64, the first reference value is 0, 0 and 1 respectively.

[0451] As a sub-example of the above embodiment, when the maximum number of SSB indexes of the first cell is 4, 8 or 64, the first reference values ​​are 0, 1 and 2 respectively.

[0452] As an example, similar to the method described above, the second reservation value increases as the maximum number of SSB indexes of the second cell increases, or the second reservation value depends on the maximum number of SSB indexes of the second cell and the number of RS resources in the first RS resource group associated with the second PCI.

[0453] As an example, the first reserved value can avoid scenarios where the RS resources used to assess whether an RLF has occurred do not include those associated with the first cell. This ensures that even if the assessment of the RLF for the second cell is prioritized, the assessment of the RLF for the first cell still meets the most basic performance requirements.

[0454] As one example, the second node N02 maintains the serving cell of the second PCI identifier.

[0455] As an example, the second node N02 maintains the cell with the first PCI identifier and the serving cell with the second PCI identifier.

[0456] As an example, when an RS resource is allocated to a cell indicated by a PCI, the RS resource is associated with the PCI.

[0457] As an example, when a PCI is used to generate an RS sequence of an RS resource, the RS resource is associated with the PCI.

[0458] As an example, when an RS resource is associated with an SSB QCL (Quasi co-location) indicated by an ssb-Index of a cell indicated by a PCI, the RS resource is associated with the PCI.

[0459] As an example, when an RS resource is synchronized with the cell downlink indicated by a PCI, the RS resource is associated with the PCI.

[0460] As an example, when an RS resource is transmitted on a cell indicated by a PCI, the RS resource is associated with the PCI.

[0461] As an example, when an RS resource is an SSB indicated by an ssb-Index of a cell indicated by a PCI, the RS resource is associated with the PCI.

[0462] As an example, the type of an RS resource is either an SSB indicated by ssb-Index or a CSI-RS resource.

[0463] As an example, the CSI-RS resource is a periodic CSI-RS resource.

[0464] As an example, an RS resource can be one of the following: SSB indicated by ssb-Index, CSI-RS resource, CSI-IM (Interference Measurement) resource, DMRS (Demodulation Reference Signal) resource, or CRS (Cell Reference Signal) resource.

[0465] As an example, any two RS resources in the first RS resource group are of the same type.

[0466] As an example, at least two RS resources in the first RS resource group are of different types.

[0467] As an example, the first PCI and the second PCI are two different TRPs.

[0468] As an example, the identifier of a TCI state is TCI-StateId.

[0469] As an example, the PCI of the Spcell (Special Cell) of the first node U01 is the second PCI, which is different from the first PCI.

[0470] As an example, the cell with the second PCI identifier is configured as the serving cell of the first node U01, while the cell with the first PCI identifier is not configured as the serving cell of the first node U01.

[0471] As one embodiment, the cell identified by the second PCI is configured to the first node U01 by SpCellConfig signaling or SCellConfig signaling, and the cell identified by the first PCI is configured to the first node U01 by RRC signaling other than SpCellConfig signaling and SCellConfig signaling.

[0472] Example 6A

[0473] Example 6A illustrates a flowchart of the transmission of RS resources according to this application, as shown in the attached diagram. Figure 6A As shown. (Attached) Figure 6A In the diagram, N04 and N05 are TRPs identified by the second PCI and the first PCI, respectively.

[0474] In step S6401, TRP N04 sends Q1 RS resources (i.e., sends RS on Q1 RS resources); TRP N05 sends Q2 RS resources (i.e., sends RS on Q2 RS resources); where Q1 and Q2 are positive integers.

[0475] In step S6101, UE U01 receives the Q1 RS resources and the Q2 RS resources.

[0476] In Example 6A, TRP N04 is identified by the second PCI or the SSB sent by TRP N04 indicates the second PCI, and TRP N05 is identified by the first PCI or the SSB sent by TRP N05 indicates the first PCI; each of the Q1 RS resources is associated with the second PCI, and each of the Q2 RS resources is associated with the first PCI.

[0477] As an example, any RS resource in the first RS resource group is one of the Q1 RS resources.

[0478] As an example, when the first RS resource is one of the Q1 RS resources, the first RS resource belongs to the first RS resource group; when the first RS resource is one of the Q2 RS resources, the first RS resource does not belong to the first RS resource group.

[0479] As an example, the second signaling switches the PCI associated with an RS resource between the second PCI and the first PCI.

[0480] Example 6B

[0481] Example 6B illustrates a flowchart of the transmission of RS resources according to this application, as shown in the attached diagram. Figure 6B As shown. (Attached) Figure 6BIn the diagram, N04 and N05 are TRPs identified by the second PCI and the first PCI, respectively.

[0482] In step S6401a, TRP N04 sends Q1 RS resources (i.e., sends RS on Q1 RS resources); TRP N05 sends Q2 RS resources (i.e., sends RS on Q2 RS resources); Q1 and Q2 are positive integers.

[0483] In step S6101a, UE U01 receives the Q1 RS resources and the Q2 RS resources.

[0484] In Example 6B, TRP N04 is identified by the first PCI or the SSB sent by TRP N04 indicates the first PCI, and TRP N05 is identified by the second PCI or the SSB sent by TRP N05 indicates the second PCI; each of the Q1 RS resources is associated with the first PCI, and each of the Q2 RS resources is associated with the second PCI.

[0485] As an example, any RS resource in the first RS resource group is one of the Q1 RS resources.

[0486] As an example, the first RS resource subgroup and the second RS resource subgroup are respectively composed of the Q1 RS resources and the Q2 RS resources.

[0487] As an example, the second signaling switches the PCI associated with an RS resource between the second PCI and the first PCI.

[0488] Example 7A

[0489] Example 7A illustrates a schematic diagram of the time-domain resources occupied by the PDCCH according to an embodiment of this application, as shown in the attached diagram. Figure 7A As shown. (Attached) Figure 7A In the search space, the squares filled by S1, S2, and S3 belong to search space #1, search space #2, and search space #3, respectively.

[0490] In Example 7A, the first signaling set includes Q1 signaling, where Q1 is a positive integer greater than 1 and not greater than 64; the Q1 signaling corresponds to Q1 control resource sets, and any one of the Q1 signaling indicates the candidate TCI state set of the corresponding control resource set; the first signaling is one of the Q1 signaling, and the first control resource set is the control resource set in the Q1 control resource sets that corresponds to the first signaling; following the order of first monitoring period from shortest to longest, and second control resource set identifier from highest to lowest, the first signaling is used to determine whether the first RS resource belongs to the first RS resource group only when the number of control resource sets ranked before the first control resource set in the Q2 control resource sets does not exceed the difference obtained by subtracting 1 from a first value; the Q2 control resource sets are composed of all control resource sets in the Q1 control resource sets that are not associated with the first PCI, and the first value is a positive integer not less than 2 and not greater than 64.

[0491] As an example, Q1 is a positive integer not greater than 4.

[0492] As an example, the first value is configurable.

[0493] As an example, the first value is no greater than 8.

[0494] As an example, the first value is no greater than 16.

[0495] As an example, the first value depends on the maximum number of SSB indexes.

[0496] As a sub-example of the above embodiment, when the maximum number of SSB indexes is 4, 8 or 64, the first value is 2, 6 and 8 respectively.

[0497] As a sub-example of the above embodiments, when the maximum number of SSB indexes is 4, 8 or 64, the first value is 2, 4 and 8 respectively.

[0498] As an example, the maximum number of SSB indexes is L. max .

[0499] As an example, the maximum number of SSB indexes is the maximum number of SSB indexes of the cell identified by the second PCI.

[0500] As an example, the maximum number of SSB indexes is the maximum number of SSB indexes of the cell identified by the first PCI.

[0501] As an example, the maximum number of SSB indexes is the larger of the maximum number of SSB indexes of the cell identified by the second PCI and the maximum number of SSB indexes of the cell identified by the first PCI.

[0502] As an example, search space #1, search space #2, and search space #3 correspond one-to-one with three control resource sets in the Q2 control resource sets; according to the appendix Figure 7A It is known that search space #1 has the longest monitoring period, therefore it should be ranked after search spaces #2 and #3. Furthermore, search spaces #2 and #3 have the same monitoring period, so we need to further compare the control resource set identifiers of their corresponding control resource sets. The search space with the higher control resource set identifier (without loss of generality, it is assumed that the control resource set identifier corresponding to search space #2 is higher than that corresponding to search space #3) should be ranked first. Based on the above analysis, the execution result of the phrase firstly, from shortest to longest monitoring period, and secondly, from highest to lowest control resource set identifier, is: search space #2, search space #3, and search space #1 are ranked in that order.

[0503] Although only three search spaces are used as an example, the above embodiment can be naturally extended to scenarios where Q2 is greater than 3.

[0504] As an example, a control resource set is not associated with the first PCI when none of the TCI states in the candidate TCI state set of a control resource set include an RS resource associated with the first PCI; and a control resource set is associated with the first PCI when each TCI state in the candidate TCI state set of a control resource set includes an RS resource associated with the first PCI.

[0505] As an example, when the active TCI state of a control resource set does not include RS resources associated with the first PCI, the control resource set is not associated with the first PCI; when the active TCI state of a control resource set includes RS resources associated with the first PCI, the control resource set is associated with the first PCI.

[0506] As an example, the candidate TCI state set of each control resource set in the Q1 control resource set is configured by RRC signaling.

[0507] As an example, the active TCI state of each control resource set in the Q1 control resource set is configured by a MAC CE.

[0508] As an example, for each control resource set in the Q1 control resource set, if the corresponding candidate TCI state set includes multiple TCI states, the active TCI state is configured by MAC CE; if the corresponding candidate TCI state set includes only one TCI state, the corresponding candidate TCI state set is the active TCI state.

[0509] As an example, for each control resource set in the Q1 control resource set, if the corresponding candidate TCI state set includes multiple TCI states, the active TCI state is configured by DCI (Dynamic Control Information).

[0510] As an example, a set of control resources is associated with the first PCI when there is a TCI state in the candidate TCI state set of a control resource set that includes an RS resource associated with the first PCI.

[0511] As an example, when a portion of the TCI states in the candidate TCI state set of a control resource set does not include RS resources associated with the first PCI, and a portion of the TCI states in the candidate TCI state set of the control resource set includes RS resources associated with the first PCI, a MAC CE is used to indicate whether the control resource set is associated with the first PCI.

[0512] Example 7B

[0513] Example 7B illustrates a flowchart for determining L RS resources according to an embodiment of this application, as shown in the attached diagram. Figure 7B As shown. (Attached) Figure 7B Step S7101 is optional.

[0514] In step S7101, the first node U01 determines L; in step S7102, L RS resources are selected from the target RS resource subgroup.

[0515] As an example, the target RS resource subgroup is a first RS resource subgroup, L is not greater than L1, and the L RS resources are no more than L1 RS resources.

[0516] As an example, the target RS resource subgroup is a second RS resource subgroup, L is not greater than L2, and the L RS resources are no more than L2 RS resources.

[0517] As an example, the UE decides how to select L RS resources from the target RS resource subgroup.

[0518] As an example, each RS resource in the target RS resource subgroup is an RS resource included in the active TCI state of a CORESET (control resource set); the first node U01 selects RS resources in the order of first monitoring period from short to long, and second control resource set identifier from high to low.

[0519] The following Example 8B provides a more specific implementation.

[0520] Example 8A

[0521] Example 8A illustrates a schematic diagram of an RS resource in the time domain according to an embodiment of this application, as shown in the attached diagram. Figure 8A As shown. The aforementioned RS resource is periodic, attached... Figure 8A In the diagram, the squares filled with W1, W2, W3, W4, and W5 represent the positions where an RS resource appears periodically in the time domain.

[0522] As an example, the first node receives a first MAC CE, which indicates that the PCI associated with the RS resource is changed from a first PCI to a second PCI.

[0523] As an example, Appendix Figure 8A The first moment in the sequence is the reception moment of the first MAC CE.

[0524] As an example, Appendix Figure 8A The first moment in the process is the moment when the RS resource indicated by the first MAC CE is associated with the second PCI.

[0525] As an example, in response to receiving the first MAC CE, the RS resource is determined to belong to the first RS resource group.

[0526] As an example, the first node receives a first DCI, which indicates that the PCI associated with the RS resource is changed from a first PCI to a second PCI.

[0527] As an example, the first DCI is a DCI used for downlink grant.

[0528] As an example, the first DCI is a Group Common DCI.

[0529] As an example, Appendix Figure 8A The first moment in the sequence is the moment the first DCI is received.

[0530] As an example, Appendix Figure 8A The first moment in the process is the moment when the RS resource indicated by the first DCI is associated with the second PCI.

[0531] As an example, in response to receiving the first MAC CE, the RS resource is determined to belong to the first RS resource group.

[0532] As an example, in the periodic occurrence of an RS resource, the occurrence associated with the first PCI cannot be used to assess whether a radio link failure has occurred. For example, see attached... Figure 8A The W1 value prior to the first moment in the timeline cannot be used to assess whether a wireless link failure has occurred.

[0533] As one embodiment, the first node receives a second MAC CE, the second MAC CE indicating from the effective time (e.g., attached). Figure 8A At the second moment, the PCI associated with the RS resource changes from the second PCI to the first PCI.

[0534] As an example, W5 after the second moment cannot be used to assess whether a wireless link failure has occurred.

[0535] As one embodiment, the first node receives a second DCI, the second DCI indicating the effective time (e.g., attached). Figure 8A At the second moment, the PCI associated with the RS resource changes from the second PCI to the first PCI.

[0536] As an example, W5 after the second moment cannot be used to assess whether a wireless link failure has occurred.

[0537] Example 8B

[0538] Example 8B illustrates a schematic diagram of the time-domain resources occupied by the PDCCH according to an embodiment of this application, as shown in the attached diagram. Figure 8B As shown. (Attached) Figure 8B In the search space, the squares filled by S1, S2, and S3 belong to search space #1, search space #2, and search space #3, respectively.

[0539] In Example 8B, the first signaling includes Q1 sub-signalings, where Q1 is a positive integer greater than 1 and not greater than 64; each of the Q1 sub-signalings corresponds to a Q1 control resource set, and any one of the Q1 sub-signalings indicates a candidate TCI state set of the corresponding control resource set; the RS resources included in the active TCI states (belonging to one of the candidate TCI state sets) of the Q1 control resource sets form a target RS resource subgroup; L RS resources are selected from the target RS resource subgroup in the order of first monitoring period from short to long, and second control resource set identifier from high to low.

[0540] As an example, Q1 is a positive integer not greater than 4.

[0541] As an example, the target RS resource subgroup is the first RS resource subgroup, and the maximum value of L is the smaller of L3 minus the difference between the number of RS resources included in the no more than L2 RS resources and L1.

[0542] As an example, search space #1, search space #2, and search space #3 correspond one-to-one with three control resource sets in the Q1 control resource sets; according to the appendix Figure 8B It is known that search space #1 has the longest monitoring period, therefore it should be ranked after search spaces #2 and #3. Furthermore, search spaces #2 and #3 have the same monitoring period, so we need to further compare the control resource set identifiers of their corresponding control resource sets. The search space with the higher control resource set identifier (without loss of generality, it is assumed that the control resource set identifier corresponding to search space #2 is higher than that corresponding to search space #3) should be ranked first. Based on the above analysis, the execution result of the phrase firstly, from shortest to longest monitoring period, and secondly, from highest to lowest control resource set identifier, is: search space #2, search space #3, and search space #1 are ranked in that order.

[0543] Although only three search spaces are used as an example, the above embodiment can be naturally extended to scenarios where Q1 is greater than 3.

[0544] As an example, a control resource set is not associated with the first PCI when none of the TCI states in the candidate TCI state set of a control resource set include an RS resource associated with the first PCI; and a control resource set is associated with the first PCI when each TCI state in the candidate TCI state set of a control resource set includes an RS resource associated with the first PCI.

[0545] As an example, when the active TCI state of a control resource set does not include RS resources associated with the first PCI, the control resource set is not associated with the first PCI; when the active TCI state of a control resource set includes RS resources associated with the first PCI, the control resource set is associated with the first PCI.

[0546] As an example, the candidate TCI state set of each control resource set in the Q1 control resource set is configured by RRC signaling.

[0547] As an example, the active TCI state of each control resource set in the Q1 control resource set is configured by a MAC CE.

[0548] As an example, for each control resource set in the Q1 control resource set, if the corresponding candidate TCI state set includes multiple TCI states, the active TCI state is configured by MAC CE; if the corresponding candidate TCI state set includes only one TCI state, the corresponding candidate TCI state set is the active TCI state.

[0549] As an example, for each control resource set in the Q1 control resource set, if the corresponding candidate TCI state set includes multiple TCI states, the active TCI state is configured by DCI (Dynamic Control Information).

[0550] As an example, a set of control resources is associated with the first PCI when there is a TCI state in the candidate TCI state set of a control resource set that includes an RS resource associated with the first PCI.

[0551] As an example, when a portion of the TCI states in the candidate TCI state set of a control resource set does not include RS resources associated with the first PCI, and a portion of the TCI states in the candidate TCI state set of the control resource set includes RS resources associated with the first PCI, a MAC CE is used to indicate whether the control resource set is associated with the first PCI.

[0554] In step S9101, the first node U01 assesses whether a radio link failure has occurred based on the first RS resource group; if yes, in response to the assessment of a radio link failure, it sends a third signaling in step S9102; if no, it terminates.

[0555] The second node N02 receives the third signaling in step S9201;

[0556] In Example 9A, the third signaling is a higher-layer signaling.

[0557] As an example, the third signaling is RRC layer signaling.

[0559] As an example, the third signaling includes an RRCReestablishmentRequest message.

[0560] As an example, the third signaling includes the RRCConnectionReestablishmentRequest message.

[0562] As an example, in response to assessing the occurrence of a wireless link failure, the first node U01 performs a PRACH (Physical Random Access Channel) preamble transmission before step S9102.

[0567] The second node N02 receives the third signaling in step S9201a;

[0568] In Example 9B, the third signaling is a higher-level signaling.

[0626] Example 11A

[0627] Example 11A illustrates a schematic diagram of the reporting cycle and evaluation cycle according to an embodiment of this application, as shown in the attached diagram. Figure 11 As shown. In the appendix Figure 11 In the diagram, the horizontal axis represents time. T1, T4, and T5 are three time points that increase sequentially. Time points T1, T4, and T5 are the times when the first type of indication is reported (if the generation conditions of the first type of indication are met). The time interval between any two adjacent times of T1, T4, and T5 is equal, and the time interval between two adjacent times of T1, T4, and T5 is equal to the reporting period. T2 and T3 are two time points that increase sequentially. The time interval between T2 and T3 is equal to the evaluation period.

[0628] As an example, the first type of indication is either out-of-sync or in-sync.

[0629] As an example, the behavior of assessing whether a wireless link failure has occurred based on a first RS resource group includes performing an assessment in each assessment cycle to determine whether a loss of synchronization has occurred and whether synchronization has been maintained based on the first RS resource group.

[0630] As an example, the behavior of assessing whether a radio link failure has occurred based on a first RS resource group includes: in each reporting cycle, if out-of-sync occurs, reporting out-of-sync to a higher layer; if synchronization is maintained, reporting in-sync to a higher layer.

[0631] As an example, time T2 is not less than time T1; time T3 is not greater than time T4.

[0632] As an example, there is an evaluation period within each reporting period.

[0635] As an example, the time when the first type of indication was last reported and the reporting period are used to determine the time when the first type of indication is reported this time.

[0636] As an example, in each reporting period, if the wireless link quality assessed by the first RS resource group is worse than a first threshold, the physical layer of the first node reports an out-of-sync to a higher layer of the first node.

[0637] As an example, in each reporting period, if the radio link quality assessed according to the first RS resource group is better than a second threshold, the physical layer of the first node reports an in-sync to the higher layer of the first node.

The time interval between any two adjacent times of T1, T4, and T5 is equal, and the time interval between two adjacent times of T1, T4, and T5 is equal to the reporting period. T2 and T3 are two time points that increase sequentially. The time interval between T2 and T3 is equal to the evaluation period.

[0645] As an example, the first type of indication is either out-of-sync or in-sync.

[0646] As one embodiment, the behavior of evaluating whether a radio link failure has occurred based on no more than L1 RS resources and no more than L2 RS resources includes performing an evaluation in each evaluation cycle to determine whether a loss of synchronization has occurred and whether synchronization has been maintained based on no more than L1 RS resources and no more than L2 RS resources.

[0647] As an example, the behavior of evaluating whether a radio link failure has occurred based on no more than L1 RS resources and no more than L2 RS resources includes determining the no more than L1 RS resources and the no more than L2 RS resources in each evaluation period.

[0648] As an example, the number of RS resources not exceeding L1 and the number of RS resources not exceeding L2 are variable in each evaluation period.

[0649] As an example, the behavior of evaluating whether a radio link failure has occurred based on no more than L1 RS resources and no more than L2 RS resources includes: in each reporting cycle, if out-of-sync occurs, reporting out-of-sync to a higher layer; if synchronization is maintained, reporting in-sync to a higher layer.

[0650] As an example, time T2 is not less than time T1; time T3 is not greater than time T4.

[0651] As an example, there is an evaluation period within each reporting period.

[0652] As an example, during the time interval between time T2 and time T3, the wireless link quality is evaluated based on the first RS resource group.

[0653] As an example, time T1 and time T4 are any two adjacent reporting times.

[0654] As an example, the time when the first type of indication was last reported and the reporting period are used to determine the time when the first type of indication is reported this time.

[0655] As an example, in each reporting period, if the wireless link quality assessed by the first RS resource group is worse than a first threshold, the physical layer of the first node reports an out-of-sync to a higher layer of the first node.

[0656] As an example, in each reporting period, if the radio link quality assessed according to the first RS resource group is better than a second threshold, the physical layer of the first node reports an in-sync to the higher layer of the first node.

[0657] As an example, the evaluation period is no longer than the reporting period.

[0658] As an example, the evaluation period is equal to the reporting period.

[0659] As an example, the evaluation period is shorter than the reporting period.

[0660] As an example, time T3 is the same as time T4.

[0661] As an example, the time T3 is different from the time T4.

[0731] In Example 13B, no more than L1 RS resources and no more than L2 RS resources are used to assess whether a radio link failure has occurred. The no more than L1 RS resources are a subset of the first RS resource subgroup, and the no more than L2 RS resources are a subset of the second RS resource subgroup. The L1 depends on at least the former of the maximum number of SSB indexes of the first cell and the maximum number of SSB indexes of the second cell, where the first cell is identified by the first PCI.

[0736] As one embodiment, the second transmitter 1301 sends a second signaling message, the second signaling message being used to indicate the PCI to which at least one RS resource in the first RS resource group is associated; wherein, the first signaling message is an RRC layer message, the second signaling message is a protocol layer message below the RRC layer, and the action receives the second signaling message before the action evaluates whether a radio link failure has occurred based on no more than L1 RS resources and no more than L2 RS resources; the PCI to which the at least one RS resource in the first RS resource group is associated is one of the first PCI and the second PCI.

[0747] Example 14

[0748] Example 14 illustrates a schematic diagram of the transmission of a first notification according to an embodiment of this application, as shown in the attached diagram. Figure 14 As shown.

[0749] In embodiment 14, the first node 1400 sends a first notification from the first protocol layer 1401 to the second protocol layer 1402 where the first node 1400 is located; the first node 1400 receives the first notification at the second protocol layer 1402; wherein the second signaling is used to trigger the first notification.

[0750] As an example, the first notification is used to determine that the second signaling has been received.

[0751] As an example, the first notification is used to indicate whether the first RS resource is associated with the first PCI.

[0752] As an example, the first notification is used to indicate whether the first RS resource is associated with the second PCI.

[0753] As an example, the first notification is used to indicate whether the first RS resource belongs to the first RS resource group.

[0754] As a sub-example of the above embodiment, the maximum number of SSB indexes of the serving cell of the first node 1400 is greater than 4.

[0755] As an example, the second protocol layer 1402 determines, based on the first notification, whether the first control resource set is associated with the first PCI.

[0756] As a sub-example of the above embodiment, the maximum number of SSB indexes of the serving cell of the first node 1400 is 4. If the second protocol layer 1402 determines whether the first control resource set is not associated with the first PCI according to the first notification, the second protocol layer 1402 determines whether the first RS resource belongs to the first RS resource set in the order of first monitoring period from short to long, and second control resource set identifier from high to low.

[0757] As an example, the first protocol layer 1401 includes a MAC layer.

[0758] As one embodiment, the first protocol layer 1401 includes a physical layer.

[0759] As one embodiment, the second protocol layer 1402 includes an RLC layer.

[0760] As one embodiment, the second protocol layer 1402 includes an RRC layer.

[0761] As an example, the first protocol layer 1401 is below the second protocol layer 1402.

[0762] As one embodiment, the first protocol layer 1401 is a lower layer of the second protocol layer 1402.

[0763] As one embodiment, the second protocol layer 1402 is an upper layer of the first protocol layer 1401.

[0764] As an example, the first protocol layer 1401 is a physical layer, and the second protocol layer 1402 is an RRC layer.

[0765] As an example, the first protocol layer 1401 is a MAC layer, and the second protocol layer 1402 is an RRC layer.

[0766] As one example, the first notification is a message between protocol layers.

[0767] As an example, the first notification is not an over-the-air message.

[0768] As an example, the first notification is transmitted within the first node 1400.

[0769] As an example, the appendix Figure 14 This is only to illustrate that the first protocol layer 1401 and the second protocol layer 1402 belong to the first node 1400; the first node 1400 also includes protocol layers or components other than the first protocol layer 1401 and the second protocol layer 1402.

[0770] As an example, the first notification is used to instruct at least one RS resource to switch its associated PCI from a first PCI to a second PCI.

[0771] As an example, the first notification is used to instruct at least one RS resource to switch its associated PCI from the second PCI to the first PCI.

[0772] As an example, the second protocol layer 1402 determines, based on the first notification, whether to reselect the no more than L1 RS resources or whether to reselect the no more than L2 RS resources.

[0773] As a sub-example of the above embodiment, if a new selection is made, if the second protocol layer 1402 determines, based on the first notification, whether the first control resource set is not associated with the first PCI, the second protocol layer 1402 determines whether the first RS resource belongs to the first RS resource set in the order of first monitoring period from short to long, and second control resource set identifier from high to low.

[0777] Example 15

[0778] Example 15 illustrates a schematic diagram of an RS resource in the time domain according to an embodiment of this application, as shown in the attached diagram. Figure 15 As shown. The aforementioned RS resource is periodic, attached... Figure 15 In the diagram, the squares filled with W1, W2, W3, W4, and W5 represent the positions where an RS resource appears periodically in the time domain.

[0779] As an example, the first node receives a first MAC CE, which indicates that the PCI associated with the RS resource is changed from a first PCI to a second PCI.

[0780] As an example, Appendix Figure 15 The first moment in the sequence is the reception moment of the first MAC CE.

[0781] As an example, Appendix Figure 15 The first moment in the process is the moment when the RS resource indicated by the first MAC CE is associated with the second PCI.

[0782] As an example, in response to receiving the first MAC CE, the RS resource is determined to belong to the first RS resource group.

[0783] As an example, the first node receives a first DCI, which indicates that the PCI associated with the RS resource is changed from a first PCI to a second PCI.

[0784] As an example, the first DCI is a DCI used for downlink grant.

[0785] As an example, the first DCI is a Group Common DCI.

[0786] As an example, Appendix Figure 15 The first moment in the sequence is the moment the first DCI is received.

[0787] As an example, Appendix Figure 15 The first moment in the process is the moment when the RS resource indicated by the first DCI is associated with the second PCI.

[0788] As an example, in response to receiving the first MAC CE, the RS resource is determined to belong to the first RS resource group.

[0789] As an example, in the occurrence of a single RS resource period, occurrences associated with different PCIs cannot be simultaneously used for radio link failure assessment within the same assessment period. For example, see attached... Figure 15 The W1 value prior to the first moment in the evaluation cannot be used to assess whether a wireless link failure occurred within the evaluation period to which W2 / W3 / W4 belong.

[0790] As one embodiment, the first node receives a second MAC CE, the second MAC CE indicating from the effective time (e.g., attached). Figure 15 At the second moment, the PCI associated with the RS resource changes from the second PCI to the first PCI.

[0791] As an example, W5 after the second moment cannot be used to evaluate whether a wireless link failure has occurred within the evaluation period to which W2 / W3 / W4 belong.

[0792] As one embodiment, the first node receives a second DCI, the second DCI indicating the effective time (e.g., attached). Figure 15 At the second moment, the PCI associated with the RS resource changes from the second PCI to the first PCI.

The method according to claim 23 or 24, characterized in that, include: In response to the transmission of the third signaling, a first notification is triggered and transmitted from the first protocol layer to the second protocol layer. Wherein, the second protocol layer is above the first protocol layer, the second signaling is the signaling of the first protocol layer, and the first notification includes information from the second protocol layer determining whether the first RS resource belongs to the first RS resource group.

26. The method according to any one of claims 21 to 25, characterized in that, The first signaling set includes Q1 signaling sequences, where Q1 is a positive integer greater than 1 and not greater than 64. The Q1 signaling messages correspond to Q1 sets of control resources. Each of the Q1 signaling signals indicates the candidate TCI state set of the corresponding control resource set. The first signaling is one of the Q1 signaling signals. The first control resource set is the control resource set among the Q1 control resource sets that corresponds to the first signaling. The method includes sending the first signaling set, in order of first monitoring period from shortest to longest, and second control resource set identifier from highest to lowest. The user equipment is configured to determine whether the first RS resource belongs to the first RS resource group based on the first signaling only if the number of control resource sets ranked before the first control resource set in the Q2 control resource sets does not exceed the difference obtained by subtracting 1 from a first value. The Q2 sets of control resources are composed of all control resource sets in the Q1 sets that are not associated with the first PCI. The first value is a positive integer that is not less than 2 and not greater than 64.
