Description

Autonomous action method and device based on terminal evaluation Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] Network-controlled mobility applies to connected terminals and can be categorized into two types: cell-level mobility and beam-level mobility. Figure 1 illustrates an inter-cell mobility scenario. As shown in Figure 1, when a terminal moves from one cell's coverage area to another, a serving cell change is required at some point.

[0003] Currently, cell-level mobility is triggered by explicit RRC (Radio Resource Control) signaling, i.e., handover. Serving cell changes are triggered by L3 (Layer 3) measurements and completed by RRC signaling. Reconfiguration with synchronization is also triggered for PCell (Primary Cell) and PSCell (Special Cell) changes, and the release of SCells (Secondary Cells) is added when applicable. The RRC-triggered handover mechanism requires the UE (also known as user equipment, terminal device, terminal, user, etc.) to at least reset the MAC (Media Access Control) entity and re-establish the RLC (Radio Link Control). RRC-managed handovers are supported with and without re-establishment of the PDCP (Packet Data Convergence Protocol) entity. For example, for DRBs (Data Radio Bearers) using RLC AM (RLC Acknowledged Mode), PDCP can be re-established with security key update or initiate data recovery without key update. For DRBs using RLC UM (RLC Unacknowledged Mode), PDCP can be re-established with security key update or remain unchanged without key update. For SRBs (Signaling Radio Bearers), PDCP can remain unchanged without key update, discard stored PDCP PDUs / SDUs, or re-establish with security key update.

[0004] As mentioned above, for the RRC-triggered handover mechanism, all cases involve a complete L2 (and L1) reset, resulting in longer latency, greater overhead, and longer disruption than beam switching mobility. The goal of L1 / L2 Triggered Mobility (LTM) enhancements is to ensure that serving cell changes via L1 / L2 signaling reduce latency, overhead, and disruption.

[0005] The aforementioned is a network-triggered cell change. Additionally, for UEs in the RRC_CONNECTED state, a cell change can be terminal-initiated. Terminal-initiated cell changes, or terminal-triggered mobility, include at least conditional reconfiguration and recovery from an RLF (Radio Link Failure) or handover failure on the MCG (Master Cell Group). Conditional reconfiguration includes conditional handover (CHO) and conditional PSCell addition / change (CPAC).

[0006] Among them, for conditional reconfiguration:

[0007] The network configures one or more candidate target special cells for the terminal in a conditional reconfiguration. The terminal evaluates the conditions of each configured candidate target special cell and applies the associated conditional reconfiguration to the target cell that meets the associated execution conditions.

[0008] FIG2 is a schematic diagram of UE behavior for conditional reconfiguration.

[0009] As shown in Figure 2, based on a received ConditionalReconfiguration IE, the UE performs the following actions:

[0010] If ConditionalReconfiguration includes condReconfigToRemoveList: execute the conditional reconfiguration removal process;

[0011] If ConditionalReconfiguration includes condReconfigToAddModList: Perform conditional reconfiguration addition / modification.

[0012] Among them, conditional reconfiguration additions / modifications include:

[0013] For each condReconfigId received in condReconfigToAddModList, the UE shall:

[0014] If an entry matching condReconfigId exists in condReconfigToAddModList in VarConditionalReconfig:

[0015] If the entry in condReconfigToAddModList includes a condExecutionCond, condExecutionCondSCG, or condExecutionCondPSCell: replace the entry with the received value of condReconfigId;

[0016] If the entry in condReconfigToAddModList includes a condRRCReconfig: replace the entry with the received value of condReconfigId;

[0017] Otherwise, add a new entry in VarConditionalReconfig for this condReconfigId; perform conditional reconfiguration evaluation.

[0018] Among them, conditional reconfiguration evaluation includes:

[0019] UE will:

[0020] For each condReconfigId in VarConditionalReconfig:

[0021] A cell having a Physical Cell Identity (PCI) matching the value indicated in ServingCellConfigCommon in reconfigurationWithSync in the received condRRCReconfig is considered an applicable cell;

[0022] For each measId included in the measIdList in the VarMeasConfig indicated in the condExecutionCond associated with the condReconfigId:

[0023] If the entry conditions applicable to this event associated with condReconfigId, i.e. the events corresponding to the condEventId(s) of the corresponding condTriggerConfig in VarConditionalReconfig, are met for all measurements after layer 3 filtering for the applicable cell, during the corresponding timeToTrigger defined for this event in VarConditionalReconfig: the event associated with measId is considered met;

[0024] If the leaving condition applicable to the event associated with condReconfigId, i.e. the event corresponding to the condEventId(s) of the corresponding condTriggerConfig in VarConditionalReconfig, is satisfied for all measurements after layer 3 filtering for the applicable cell, the corresponding timeToTrigger period defined for this event in VarConditionalReconfig: the event associated with measId is considered not satisfied;

[0025] If for a target candidate cell in the stored condRRCReconfig, all events associated with measId(s) in condTriggerConfig are satisfied:

[0026] The target candidate cell associated with condReconfigId in the stored condRRCReconfig is considered to be a triggered cell;

[0027] Initiates conditional reconfiguration execution.

[0028] Among them, the conditional reconfiguration execution includes:

[0029] UE will:

[0030] If there is a triggered cell: selecting a triggered cell as a selected cell for conditional reconfiguration execution;

[0031] For the selected cell for conditional reconfiguration execution, the stored condRRCReconfig of this selected cell is applied.

[0032] Among them, the network provides the configuration parameters of the target special cell in the ConditionalReconfiguration IE. In NR-DC (dual connection), the UE may receive two independent conditionalReconfigurations: a conditionalReconfiguration associated with the MCG (primary cell group), that is, included in the RRCReconfiguration message received via SRB1; a conditionalReconfiguration associated with the SCG (secondary cell group), that is, included in the RRCReconfiguration message received via SRB3, or included in an RRCReconfiguration message encapsulated in an RRCReconfiguration message received via SRB1. In this case, the UE maintains two independent VarConditionalReconfigs, one associated with each conditionalReconfiguration; unless otherwise explicitly stated, the UE performs all the above processes independently for each conditionalReconfiguration and the associated VarConditionalReconfig; for VarConditionalReconfigs associated with the same cell group, the UE performs the measurement process.

[0033] As previously mentioned, conditional reconfiguration includes two scenarios: conditional handover (CHO) and conditional PSCell change. Conditional handover is defined as a handover executed by the UE when one or more handover execution conditions are met. The UE begins evaluating these execution conditions upon receiving the CHO configuration and ceases evaluating them once the handover is executed.

[0034] The following principles apply to CHO:

[0035] The CHO configuration includes the configuration of the CHO candidate cells generated by the candidate gNB(s) and the execution conditions generated by the source gNB;

[0036] An execution condition can include one or two trigger conditions (CHO events A3 / A5). The CHO execution condition only supports a single RS (Reference Signal) type and a single candidate cell, and can be configured with up to two different trigger quantities (such as Reference Signal Received Power RSRP and Reference Signal Received Quality RSRQ, RSRP and Signal to Interference and Noise Ratio SINR, etc.).

[0037] When a HO (handover) command is received (without CHO configuration) before any CHO execution conditions are met, the UE performs the HO procedure regardless of any CHO configuration received previously;

[0038] When performing CHO, that is, from the time the UE starts synchronizing with the target cell, the UE does not monitor the source cell.

[0039] The process of CHO in AMF (Access and Mobility Management Function) is shown in Figure 3. The specific process can be referred to related technologies and will not be repeated here.

[0040] On the other hand, Layer 3-based mobility has evolved over several releases, including conditional handover (CHO) and other conditional mobility procedures (CPAC and SCPAC). These procedures achieve high robustness by ensuring that no prior signaling interaction with the source cell is required. LTM, introduced in Release 18, provides short outage times, but its robustness is not as good as that of Layer 3-based mobility procedures. In Release 19, enhancements will be defined to enable the system to benefit from both high robustness and short outages.

[0041] In Rel-19, the objectives of the work item include: defining support for inter-CU Layer 2 Mobility (LTM), measurement-related enhancements to support LTM, defining support conditions for LTM, and, if necessary, defining RRM (Radio Resource Management) requirements related to the above objectives.

[0042] In the above objectives, support for inter-CU Layer 2 Mobility (LTM) is defined including:

[0043] Prioritize the case where the CU (Central Unit) acts as the MN (Master Node) when DC (Dual Connectivity) is not configured;

[0044] As a secondary priority, it supports the configuration of NR-DC, CU as SN (Secondary Node) and the MN remains unchanged;

[0045] As a secondary priority, it supports the configuration of NR-DC and CU as MN and the SCG (Secondary Cell Group) remains unchanged or is released. Note: This excludes the case where both MCG (Master Cell Group) and SCG are configured with LTM.

[0046] According to Rel-18 LTM, support for subsequent LTM mobility procedures is defined, with the goal of avoiding inter-cell handover RRC (Radio Resource Control) configuration; and security key handling is negotiated using SA3.

[0047] Among the above objectives, it is worth noting that the Rel-18 intra-CU LTM process is considered as a baseline for increasing inter-CU support.

[0048] Among the above goals, measurement-related enhancements to support LTM include:

[0049] Measurement-related enhancements are applicable to intra-CU MCG / SCG LTM and inter-CU MCG / SCG LTM;

[0050] Define the necessary components to support event-triggered L1 measurement reporting; where RAN1 and RAN2 independently advance event-triggered measurement targets within their respective MIMO and mobility enhancement WIs; review progress at RAN#105 to see if targets need to be modified to avoid / manage any duplication of work;

[0051] Define CSI-RS measurements to support the LTM process and ensure necessary physical layer operations on CSI-RS based beam management and / or other pre-LTM candidate cells.

[0052] In the above objectives, the definition of supporting conditions LTM includes:

[0053] Define the conditions for triggering LTM evaluated by the UE;

[0054] The goal is to support conditional LTM that includes subsequent LTM;

[0055] Prioritize intra-CU LTM;

[0056] RAN#105 is the checkpoint for the review. RAN WG work will not begin before this checkpoint.

[0057] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0058] Summary of the Invention

[0059] LTM is a process in which the gNB (also known as base station, network equipment, network, etc.) receives Layer 1 (L1) measurement reports from the UE. Based on these reports, the gNB changes the UE's serving cell via a cell change command sent via a MAC Control Element (MAC CE). The MAC-triggered cell change mechanism (i.e., LTM cell handover) requires the UE to at least reset the MAC entity. The RLC handling depends on the network configuration.

[0060] Figure 4 is a schematic diagram of the overall LTM process. The basic process on the air interface is applicable to MCG LTM or SCG LTM. As shown in Figure 4, the process includes the following steps:

[0061] 1. The UE sends a MeasurementReport message to the gNB, in which the gNB-CU decides to configure LTM and initiates LTM preparation.

[0062] 2. The gNB sends an RRCReconfiguration message to the UE including the LTM candidate configuration.

[0063] 3. The UE stores the LTM candidate configuration and sends an RRCReconfigurationComplete message to the gNB.

[0064] 4a. Before receiving the cell change command, the UE performs DL (Downlink, downlink, referred to as downlink) synchronization with the candidate cell;

[0065] 4b. When UE-based TA (Timing Advance) measurement is configured, the UE obtains the TA value of the candidate cell through measurement;

[0066] It is worth noting that before receiving the cell change command, the UE performs an early TA acquisition with the candidate cell at the request of the network. This is done through CFRA (Contention Free Random Access), which is triggered by the PDCCH (Physical Downlink Control Channel) command of the source cell, and then the UE sends a preamble to the indicated candidate cell, as shown in Figure 5, which is a schematic diagram of the random access process. In order to minimize the data interruption of the source cell caused by the CFRA to the candidate cell, the UE does not receive a random access response from the network for the purpose of obtaining the TA value of the candidate cell indicated in the cell change command. The UE does not maintain the TA timer of the candidate cell, but relies on the network implementation to ensure the validity of the TA.

[0067] 5. The UE performs L1 measurements on the configured candidate cells and sends an L1 measurement report to the gNB. L1 measurements should be performed whenever RRC reconfiguration (step 2) is applicable.

[0068] 6. The gNB decides to perform a cell handover to a target cell and sends a MAC CE triggering a cell handover including the candidate configuration index of the target cell. The UE switches to the target cell and applies the configuration indicated by the candidate configuration index.

[0069] 7. If the UE does not have a valid TA for the target cell, the UE performs a random access procedure to the target cell;

[0070] 8. The UE completes the LTM cell handover process by sending an RRCReconfigurationComplete message to the target cell.

[0071] It is worth noting that if the UE performs a random access procedure in step 7, the UE considers the LTM cell handover to have been successfully completed when the random access procedure is successfully completed. For RACH-less LTM, that is, when step 7 is not performed, the UE considers the LTM cell handover to have been successfully completed when it determines that the network has successfully received its first UL data.

[0072] In addition, for the random access procedure on LTM candidate cells used for early UL TA acquisition, a CFRA triggered by a PDCCH order is used. The UE sends MSG1 (Message 1) to the cell and does not listen for responses from the cell. To support UE power ramping, the UE can retransmit MSG1 as instructed by the network.

[0073] In addition, for subsequent LTM, the LTM candidate configuration provided in step 2 can be used to perform steps 4 to 8 multiple times, that is, the subsequent LTM is achieved by repeating the early synchronization, LTM cell switching execution and LTM cell switching completion steps and not releasing other LTM candidate configurations after each LTM cell switching is completed.

[0074] The inventors have discovered that layer 1 measurements for LTM mobility only support periodic reporting and network-triggered semi-continuous reporting, which increases signaling overhead.

[0075] In response to at least one of the above problems or other similar problems, embodiments of the present application provide a method and apparatus for autonomous action based on terminal evaluation.

[0076] According to one aspect of an embodiment of the present application, a device for autonomous action based on terminal evaluation is configured on a terminal device, wherein the device includes:

[0077] a receiving unit configured to receive a first configuration sent by a network device, wherein the first configuration is associated with a first condition based on layer 1 or layer 3 measurement;

[0078] A processing unit, which performs at least one of the following processing when the first condition is met: layer 1 measurement reporting, early uplink synchronization on the candidate cell, and LTM execution to the target cell.

[0079] One of the beneficial effects of the embodiments of the present application is that: according to the embodiments of the present application, when the conditions (first conditions) based on layer 1 measurement or layer 3 measurement are met, the terminal device performs at least one of layer 1 measurement reporting, early uplink synchronization on the candidate cell, and LTM execution to the target cell, thereby realizing autonomous action and saving signaling overhead.

[0109] Embodiments of the first aspect

[0110] The embodiment of the present application provides a method for autonomous action based on terminal evaluation, which is described from the perspective of a terminal device.

[0111] FIG6 is a schematic diagram of a method for autonomous action based on terminal evaluation according to an embodiment of the present application. As shown in FIG6 , the method includes:

[0112] 610: The terminal device receives a first configuration sent by the network device, where the first configuration is related to a first condition based on layer 1 or layer 3 measurement.

[0113] 620: When the first condition is met, the terminal device performs at least one of the following processes: layer 1 measurement reporting, early uplink synchronization on the candidate cell, and LTM execution to the target cell.

[0114] It is worth noting that FIG6 above only schematically illustrates an embodiment of the present application, and the present application is not limited thereto. For example, other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above content, and are not limited to the description of FIG6 above.

[0115] For example, as shown in FIG6 , the method may further include:

[0116] 615: The terminal device evaluates whether the first condition is satisfied. The first condition will be described later.

[0117] In the above embodiment, evaluating whether the first condition is satisfied may also be determining whether to execute at least one of the above processes. For example, if the first condition is satisfied, it means that at least one of the above processes may be executed.

[0118] Figure 7 is a schematic diagram of a processing flow of a terminal device according to the above embodiment. As shown in Figure 7, after receiving the measurement configuration, the terminal device first performs an evaluation, namely, evaluating whether the first condition is satisfied or whether to perform at least one of the above processes. If the first condition is satisfied or at least one of the above processes can be performed, the terminal device performs at least one of L1 measurement reporting, UL synchronization, and LTM execution, and then terminates the evaluation.

[0119] According to the above embodiment, when the conditions based on layer 1 measurement or layer 3 measurement (first condition) are met, the terminal device performs at least one of layer 1 measurement reporting, early uplink synchronization on the candidate cell, and LTM execution to the target cell, thereby realizing autonomous action and saving signaling overhead.

[0120] Regarding the configuration related to the first condition based on layer 1 measurement, in some embodiments, the network device uses RRC signaling to configure the first condition based on layer 1 measurement. For example, the first configuration is sent via RRC signaling, and the first condition based on layer 1 measurement is included in the first configuration.

[0121] In the above embodiment, in some possible implementations, the physical layer of the terminal device may evaluate whether the above first condition is satisfied, and provide an indication of whether the first condition is satisfied and / or information related to the first condition to the MAC layer of the terminal device. The information related to the first condition may be, for example, cell information that satisfies the first condition, cell information that does not satisfy the first condition, measurement results related to the first condition, etc. Thus, the MAC layer of the terminal device may determine whether (one or more candidate cells) satisfy the above first condition based on the evaluation of the physical layer, and if so, perform operation 620.

[0122] In the above embodiment, in other possible implementations, the MAC layer of the terminal device may evaluate whether the first condition is met based on an indication or information related to L1 measurement provided by the physical layer. The indication or information related to L1 measurement may be, for example, an L1 measurement result. Thus, the MAC layer of the terminal device may determine whether the first condition is met based on its own evaluation, and if so, perform operation 620.

[0123] Regarding the configuration related to the first condition based on layer 3 measurement, in some embodiments, the network device uses RRC signaling to configure the first condition based on layer 3 measurement. For example, the first configuration is sent via RRC signaling, and the first condition based on layer 3 measurement is included in the first configuration.

[0124] In the above embodiment, in some possible implementations, the RRC layer of the terminal device evaluates whether the above first condition is satisfied, and provides an indication of whether the first condition is satisfied and / or information related to the first condition to the MAC layer of the terminal device. The information related to the first condition may be, for example, cell information that satisfies the first condition, cell information that does not satisfy the first condition, measurement results related to the first condition, etc. Thus, the MAC layer of the terminal device can determine whether the above first condition is satisfied based on the evaluation of the RRC layer, and if so, perform operation 620.

[0125] In the above embodiment, in other possible implementations, the MAC layer of the terminal device may evaluate whether the first condition is met based on an indication or information related to L3 measurement provided by the RRC layer. The indication or information related to L3 measurement may be, for example, an L3 measurement result. Thus, the MAC layer of the terminal device may determine whether the first condition is met based on its own evaluation, and if so, perform operation 620.

[0126] Regarding the configuration related to the first condition based on layer 1 measurement or layer 3 measurement, in some further embodiments, the network device configures a count value and / or timer value for the first condition via RRC signaling. For example, the first configuration is sent via RRC signaling, and the count value and / or timer value for the first condition is included in the first configuration.

[0127] In the above embodiment, the count value may be a counter value, or a maximum value for counting, etc.; the timer value may also be a window value, a duration, etc.

[0128] In the above embodiment, the MAC layer of the terminal device may evaluate whether the first condition is satisfied based on the above first configuration. Optionally, the physical layer of the terminal device may further provide the MAC layer with an indication or information related to L1 measurement, such as an L1 measurement result, and the MAC layer of the terminal device may evaluate whether the first condition is satisfied based on the above first configuration and / or the indication or information related to the L1 measurement.

[0129] In the above embodiment, the first condition is predefined, for example, it can be defined in the standard, and this application does not limit its implementation method.

[0130] In the above embodiment, a configuration for enabling or indicating the above count value and / or timer value may be added. For example, in the above first configuration, indication information may also be included, and the indication information is used to indicate whether the above count value and / or timer value is allowed or enabled.

[0131] Regarding the first condition above, in some embodiments, the first condition includes at least one of the following:

[0132] The serving cell becomes better than the first value;

[0133] The serving cell becomes worse than a second value;

[0134] The candidate cell becomes better than the third value;

[0135] The serving cell or the special cell becomes worse than a fourth value, and the candidate cell becomes better than a fifth value;

[0136] The candidate cell becomes better than the serving cell or special cell;

[0137] The first time has passed since the last early uplink synchronization or layer 1 measurement report was performed on the candidate cell;

[0138] The service area has deteriorated.

[0139] In the above embodiment, the serving cell becomes better than the first value, for example, refers to at least one of the following:

[0140] The number of first indications of serving cells received from lower layers (e.g., physical layer) reaches a value n1;

[0141] During t1, the number of first indications of serving cells received from lower layers (e.g., physical layer) reaches a value n1;

[0142] The number of consecutive first indications of the serving cell received from lower layers (eg, physical layer) reaches a value n1.

[0143] In the above embodiment, the first indication is used to indicate that the L1 measurement result (e.g., RSRP and / or SINR) of the serving cell is better than a first value. For example, when the L1 measurement result of at least one reference signal (e.g., all reference signals or all configured reference signals) of the serving cell is better than the first value, the lower layer (e.g., the physical layer) provides the first indication to the upper layer (e.g., the MAC layer); when the number of the first indications reaches a value n1, or the number of the first indications reaches a value n1 during a period t, or the number of consecutive first indications reaches a value n1, it is considered that the serving cell has become better than the first value, or the first condition is satisfied, or one of the above processes can be performed.

[0144] In the above example, the MAC layer may define at least one of the first counter, the first variable, the first timer, and the second timer to determine whether the serving cell becomes better than the first value in combination with their values ​​or states.

[0145] For example, when the MAC layer receives the first indication from the lower layer, the first counter or the first variable is increased by 1; when the first counter or the first variable is equal to (or greater than) n1, it is considered that the serving cell becomes better than the first value or the first condition is met or one of the above processes can be performed.

[0146] For another example, when the MAC layer receives a first indication from a lower layer, the first counter or first variable is incremented by 1. If the first indication has not been received before and the first timer is not running, the first timer is started. When the first counter or first variable is equal to (or greater than) n1, if the first timer is running, it is considered that the serving cell has become better than the first value, or the first condition is satisfied, or one of the above processes can be performed. When the first timer times out, the first counter or first variable is set to 0. For example, the duration of the first timer is the above-mentioned t.

[0147] For another example, when the MAC layer receives the first indication from the lower layer, if the second timer is running, the first counter or the first variable is incremented by 1, and the second timer is restarted. When the first counter or the first variable is equal to (or greater than) n1, it is considered that the serving cell has become better than the first value, or the first condition is satisfied, or one of the above processes can be performed. When the first timer times out, the first counter or the first variable is set to 0. For example, the duration of the second timer is the above-mentioned t2.

[0148] In the above example, the name of the first counter and / or the first variable may be GoodInstance_Counter, but the present application is not limited thereto.

[0149] In the above embodiment, consecutive first indications refer to two first indications without any other indication between them, or the two first indications are received within a period t2. For example, when a first indication is received, timer T2 is started. If timer T2 is still running (not timed out) when the next first indication is received, the two first indications are considered to be consecutive first indications.

[0150] In the above embodiment, the first value is a threshold value used for comparison with the above serving cell, which may be RSRP, SINR, or a combination of the two.

[0151] The above embodiment is applicable to layer 1 measurement reporting, that is, according to the above embodiment, when the serving cell becomes better than the first value, the terminal device can perform layer 1 measurement reporting.

[0152] In the above embodiment, the serving cell becomes worse than the second value, for example, refers to at least one of the following:

[0153] the number of second indications of serving cells received from a lower layer (e.g., a physical layer) reaches a value n2;

[0154] During t1, the number of second indications of serving cells received from a lower layer (e.g., a physical layer) reaches a value n2;

[0155] The number of consecutive second indications of the serving cell received from lower layers (eg, physical layer) reaches a value n2.

[0156] In the above embodiment, the second indication is used to indicate that the L1 measurement result (e.g., RSRP and / or SINR) of the serving cell is worse than a second value. For example, when the L1 measurement result of at least one reference signal (e.g., all reference signals or all configured reference signals) of the serving cell is worse than the second value, the lower layer (e.g., the physical layer) provides the second indication to the upper layer (e.g., the MAC layer); when the number of the second indications reaches a value n2, or the number of the second indications reaches a value n2 during a period t, or the number of consecutive second indications reaches a value n2, it is considered that the serving cell has become worse than the second value, or the first condition is satisfied, or one of the above processes can be performed.

[0157] In the above example, the MAC layer may define a counter and / or a variable and / or a timer to determine whether the serving cell has become worse than the second value in combination with the value of the counter and / or the variable and / or the state of the timer. The specific example is similar to the above and will not be repeated here.

[0158] In the above embodiment, consecutive second indications mean that there is no other indication between two second indications, or that the two second indications are received within a period t2. For example, when a second indication is received, timer T2 is started. If timer T2 is still running (not timed out) when the next second indication is received, the two second indications are considered to be consecutive second indications.

[0159] In the above embodiment, the second value is a threshold value used for comparison with the above serving cell, which may be RSRP, SINR, or a combination of the two.

[0160] The above embodiment is applicable to layer 1 measurement reporting, early uplink synchronization on the candidate cell, and LTM execution to the target cell. That is, according to the above embodiment, when the serving cell becomes worse than the second value, the terminal device can perform layer 1 measurement reporting, early uplink synchronization on the candidate cell, and / or LTM execution to the target cell.

[0161] In the above embodiment, the candidate cell becomes better than the third value, for example, refers to at least one of the following:

[0162] the number of third indications of candidate cells received from a lower layer (e.g., a physical layer) reaches a value n3;

[0163] During t1, the number of third indications of candidate cells received from a lower layer (e.g., a physical layer) reaches a value n3;

[0164] The number of consecutive third indications of candidate cells received from lower layers (eg physical layer) reaches a value n3.

[0165] In the above embodiment, the third indication is used to indicate that the L1 measurement result (e.g., RSRP and / or SINR) of the candidate cell is better than a third value. For example, when the L1 measurement result of at least one reference signal (e.g., all reference signals or all configured reference signals) of the candidate cell is better than the third value, the physical layer provides the third indication to the upper layer (e.g., the MAC layer); when the number of the third indications reaches a value n3, or the number of the third indications reaches a value n3 during a period t, or the number of consecutive third indications reaches a value n3, the candidate cell is considered to be better than the third value, or the first condition is satisfied, or one of the above processes can be performed.

[0166] In the above example, the MAC layer may define a counter and / or variable and / or timer to determine whether the candidate cell has become better than the third value in combination with the value of the counter and / or variable and / or the state of the timer. The specific example is similar to the above and will not be repeated here.

[0167] In the above embodiment, consecutive third indications refer to two third indications without any other indication between them, or the two third indications are received within a period t2. For example, when a third indication is received, timer T2 is started. If timer T2 is still running (not timed out) when the next third indication is received, the two third indications are considered consecutive third indications.

[0168] In the above embodiment, the third value is a threshold value used for comparison with the above serving cell, which may be RSRP, SINR, or a combination of the two.

[0169] The above embodiment is applicable to layer 1 measurement reporting, early uplink synchronization on the candidate cell, and LTM execution to the target cell. That is, according to the above embodiment, when the candidate cell becomes better than the third value, the terminal device can perform layer 1 measurement reporting, early uplink synchronization on the candidate cell, and / or LTM execution to the target cell.

[0170] In the above embodiment, the serving cell or the special cell becomes worse than the fourth value, and the candidate cell becomes better than the fifth value, for example, refers to at least one of the following:

[0171] the number of fifth indications of candidate cells received from a lower layer (e.g., a physical layer) reaches a value n1, and the number of fourth indications of serving cells or special cells received from the physical layer reaches a value n2;

[0172] During t1, the number of fifth indications of candidate cells received from a lower layer (e.g., a physical layer) reaches a value n1, and the number of fourth indications of serving cells or special cells received from the physical layer reaches a value n2;

[0173] The number of consecutive fifth indications of candidate cells received from lower layers (eg, physical layer) reaches a value n1, and the number of consecutive fourth indications of serving cells or special cells received from the physical layer reaches a value n2.

[0174] In the above embodiment, the fifth indication is used to indicate that the L1 measurement (e.g., RSRP and / or SINR) result of the candidate cell is better than the fifth value, and the fourth indication is used to indicate that the L1 measurement (e.g., RSRP and / or SINR) result of the serving cell or special cell is worse than the fourth value. For example, when the L1 measurement result of at least one reference signal (e.g., all reference signals or all configured reference signals) of the candidate cell is better than the fifth value, the lower layer (e.g., the physical layer) provides the fifth indication to the upper layer (e.g., the MAC layer); when the L1 measurement result of at least one reference signal (e.g., all reference signals or all configured reference signals) of the serving cell or the special cell is worse than the fourth value, the lower layer (e.g., the physical layer) provides the fourth indication to the upper layer (e.g., the MAC layer); when the number of the fifth indications reaches the value n1 and the number of the fourth indications reaches the value n2, or, during period t, the number of the fifth indications reaches the value n1 and the number of the fourth indications reaches the value n2, or, the number of consecutive fifth indications reaches the value n1 and the number of consecutive fourth indications reaches the value n2, it is considered that the serving cell or the special cell becomes worse than the fourth value and the candidate cell becomes better than the fifth value, or it is considered that the first condition is satisfied or one of the above processes can be performed.

[0175] In the above example, the MAC layer may define a counter and / or variable and / or timer to determine whether the serving cell or special cell has become worse than the fourth value and whether the candidate cell has become better than the fifth value in combination with the value of the counter and / or variable and / or the state of the timer. The specific example is similar to the above and will not be repeated here.

[0176] In the above embodiment, consecutive fourth indications refer to two fourth indications without another indication between them, or the two fourth indications are received within a period t2. For example, when a fourth indication is received, timer T2 is started. If timer T2 is still running (not timed out) when the next fourth indication is received, the two fourth indications are considered consecutive. The meaning of consecutive fifth indications is similar and will not be further described here.

[0177] In the above embodiment, the fourth value is a threshold value for comparison with the above serving cell or special cell, and the fifth value is a threshold value for comparison with the above candidate cell. The threshold value may be RSRP, SINR, or a combination of the two.

[0178] The above embodiment is applicable to layer 1 measurement reporting, early uplink synchronization on the candidate cell, and LTM execution to the target cell. That is, according to the above embodiment, when the serving cell or the special cell becomes worse than the fourth value and the candidate cell becomes better than the fifth value, the terminal device can perform layer 1 measurement reporting, early uplink synchronization on the candidate cell, and / or LTM execution to the target cell.

[0179] In the above embodiment, the candidate cell becomes better than the serving cell or the special cell, for example, refers to at least one of the following:

[0180] the number of sixth indications of candidate cells received from a lower layer (e.g., a physical layer) reaches a value n3;

[0181] During t1, the number of sixth indications of candidate cells received from a lower layer (e.g., a physical layer) reaches a value n3;

[0182] The number of consecutive sixth indications of candidate cells received from lower layers (eg, physical layer) reaches a value n3.

[0183] In the above embodiment, the sixth indication is used to indicate that the L1 measurement result (e.g., RSRP and / or SINR) of the candidate cell is better than the L1 measurement result (e.g., RSRP and / or SINR) of the serving cell or the special cell. For example, when the L1 measurement result of at least one reference signal (e.g., all reference signals or all configured reference signals) of the candidate cell is better than the L1 measurement result of at least one reference signal (e.g., all or any reference signals) of the serving cell or the special cell by a certain offset, the lower layer (e.g., the physical layer) provides the sixth indication to the upper layer (e.g., the MAC layer); when the number of the sixth indications reaches a value n3, or the number of the sixth indications reaches a value n3 during a period t, or the number of consecutive sixth indications reaches a value n3, it is considered that the candidate cell becomes better than the serving cell or the special cell, or the first condition is satisfied, or one of the above processes can be performed.

[0184] In the above example, the MAC layer may define a counter and / or variable and / or timer to determine whether the candidate cell has become better than the serving cell or the special cell in combination with the value of the counter and / or variable and / or the state of the timer. The specific example is similar to the above and will not be repeated here.

[0185] In the above embodiment, consecutive sixth indications refer to two sixth indications without any other indication between them, or the two sixth indications are received within a period t2. For example, when a sixth indication is received, timer T2 is started. If timer T2 is still running (not timed out) when the next sixth indication is received, the two sixth indications are considered consecutive sixth indications.

[0186] The above embodiment is applicable to layer 1 measurement reporting, early uplink synchronization on the candidate cell, and LTM execution to the target cell. That is, according to the above embodiment, when the candidate cell becomes better than the serving cell or the special cell, the terminal device can perform layer 1 measurement reporting, early uplink synchronization on the candidate cell, and / or LTM execution to the target cell.

[0187] In the above embodiment, the first time has passed since the last execution of layer 1 measurement reporting or early uplink synchronization on the candidate cell, which is applicable to layer 1 measurement reporting and early uplink synchronization on the candidate cell.

[0188] For example, the first condition is that a first time has passed since the last execution of early uplink synchronization on the candidate cell. If the first time has passed since the last execution of early uplink synchronization on the candidate cell, the terminal device performs early uplink synchronization on the candidate cell.

[0189] Similarly, the first condition is that a first time has passed since the last layer 1 measurement report was performed. If the first time has passed since the last layer 1 measurement report was performed, the terminal device performs early uplink synchronization on the candidate cell; or if the first time has passed since the last layer 1 measurement report was performed, the terminal device performs layer 1 measurement reporting.

[0190] In the above embodiment, if the first condition is that a first time has passed since the last early uplink synchronization on the candidate cell was performed, the first time may be determined according to the TA timer.

[0191] In the above embodiment, the serving cell deterioration, for example, refers to at least one of the following:

[0192] During t1, the number of (continuous) uplink NACKs (Negative Acknowledgement) reaches n4.

[0193] (During t1,) the number of (consecutive) unsuccessful transmissions reaches value n4;

[0194] (During t1,) the number of (consecutive) CG (configured grant) transmission timeouts reaches the value n4.

[0195] For example, when the number of uplink NACKs reaches n4, or the number of consecutive uplink NACKs reaches n4, or the number of consecutive uplink NACKs during t1 reaches n4, it is considered that the serving cell is deteriorated or the first condition is met or one of the above processes can be performed.

[0196] For another example, when the number of unsuccessful transmissions reaches n4, or the number of consecutive unsuccessful transmissions reaches n4, or the number of consecutive unsuccessful transmissions during t1 reaches n4, it is considered that the serving cell has deteriorated or the first condition is met or one of the above processes can be performed.

[0197] For another example, when the number of CG transmission timeouts reaches the value n4, or the number of consecutive CG transmission timeouts reaches the value n4, or the number of consecutive CG transmission timeouts during period t1 reaches the value n4, it is considered that the service cell has deteriorated or the first condition is met or one of the above processes can be performed.

[0198] In the above example, the MAC layer may define a counter and / or variable and / or timer to determine whether the serving cell has deteriorated in combination with the value of the counter and / or variable and / or the state of the timer. The specific example is similar to the above and will not be repeated here.

[0199] In the above embodiment, consecutive uplink NACKs refer to two uplink NACKs with no other information between them, or two uplink NACKs received within a period of t2. For example, when an uplink NACK is received, timer T2 is started. If timer T2 is still running (not timed out) when the next uplink NACK is received, the two uplink NACKs are considered consecutive uplink NACKs. The "other information" is non-NACK information. Information other than NACKs can be ACK (acknowledgement, positive feedback), which is used to schedule new UL grants / DL allocations, etc.

[0200] In the above embodiment, the continuous uplink NACK may correspond to each terminal device, each MAC entity, or each HARQ (Hybrid Automatic Repeat-reQuest) process, and this application does not impose any restrictions on this.

[0201] In the above embodiment, consecutive unsuccessful transmissions refer to no successful transmission between two unsuccessful transmissions, or two unsuccessful transmissions are received within the period t2.

[0202] In the above embodiment, continuous unsuccessful transmission and CG transmission can correspond to each terminal device, each MAC entity, each HARQ process, or each CG configuration, and this application does not impose any restrictions on this.

[0203] The first condition is described above by way of example, but the present application is not limited thereto, and appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0204] In the above description, "reach" may mean equal to (=), or not smaller than (not smaller than), or greater than (>larger than), or greater than or equal to (>=). For example, when a counter and / or variable is defined, "reach" means that the counter value and / or variable is equal to or not smaller than or greater than or equal to the above value n1, the above value n2, the above value n3, or the above value n4.

[0205] Regarding the terminal device performing layer 1 measurement reporting, in some embodiments, the terminal device may generate a MAC CE and perform layer 1 measurement reporting through the MAC CE.

[0206] In the foregoing embodiment, the MAC CE may include at least one of the following:

[0207] Cell information;

[0208] Cell type information;

[0209] Reference signal information;

[0210] Measurement result information;

[0211] An indication of the event that was triggered.

[0212] The above-mentioned cell information may be cell information of the serving cell and / or cell information of the candidate cell, and may be indicated by a bitmap. For example, if the bit value corresponding to the serving cell or candidate configuration in the bitmap is set to 1, it indicates that the L1 measurement result of the above-mentioned cell is included in the MAC CE. That is, if the L1 measurement result of a certain cell is included, the value corresponding to the serving cell or candidate configuration in the bitmap is set to 1, otherwise it is set to 0. The above-mentioned serving cells can be up to 32, occupying 4 bytes, and the above-mentioned candidate configurations can be up to 8, occupying 1 byte.

[0213] The cell information may also be indicated by a cell index. For example, the MAC CE includes the serving cell index or candidate configuration ID or PCI information corresponding to the cell. That is, if the L1 measurement result of a cell is included, the serving cell index or candidate configuration identifier (ID) or physical cell identifier (PCI) information corresponding to the cell is included.

[0214] The cell information can also be indicated jointly by a bitmap and a cell index. For example, if the number of cells included in the L1 measurement results is less than x (e.g., x=2), the cell index is used; otherwise, the bitmap is used. For another example, if the number of cells included in the L1 measurement results is greater than x (e.g., x=2) and the highest index of the serving cell including the L1 measurement results is less than y (e.g., y=8), the bitmap is used; otherwise, the cell index is used.

[0215] The cell type information indicates whether the cell information is that of a serving cell or a candidate cell. For example, if the cell type information is set to 1, it indicates that the cell information is that of a candidate cell; otherwise, it indicates that the cell information is that of a serving cell. Alternatively, if the cell type information is set to 0, it indicates that the cell information is that of a candidate cell; otherwise, it indicates that the cell information is that of a serving cell.

[0216] The above-mentioned reference signal information may, for example, include at least one of an SSB index (index), a CSI-RS resource identifier (ID), and an RS index (index), but the present application is not limited thereto.

[0217] The above measurement result information may include, for example, at least one of L1 RSRP and L1 SINR, but the present application is not limited thereto.

[0218] The indication information of the above-mentioned triggered event may include, for example, at least one of an event identifier (ID) and an event index (index), but the present application is not limited thereto.

[0219] In the above embodiment, the MAC CE may be a normal MAC CE, i.e., one that does not support truncation, or a truncated MAC CE. If the MAC CE is a truncated MAC CE, the truncated MAC CE may include the L1 measurement result of the best candidate cell. This allows the terminal to promptly report available candidate cells and corresponding measurement results.

[0220] In the above embodiment, the logical channel priority (LCP) of the above MAC CE may be the same as the priority of the enhanced BFR (Beam Failure Recovery) MAC CE, or may be lower or higher than the priority of the enhanced BFR MAC CE, or may be higher or lower than the priority of the LBT (listen before talk) failure, or may be higher or lower than the priority of the sidelink authorization configuration confirmation MAC CE. This application does not impose any restrictions on this.

[0221] In the above embodiment, the terminal device may also trigger a Scheduling Request (SR). For example, if the result of the logical channel priority is that there is no uplink grant available for new transmission that can accommodate the MAC CE, the terminal device triggers a Scheduling Request.

[0222] In the above embodiment, the scheduling request may use a specific SR configuration for layer 1 measurement or use another SR configuration (for example, referred to as a first SR configuration). The first SR configuration may be at least one of an SR configuration reported by a BSR (Buffer Status Report), an SR configuration reported by a BFR, and an SR configuration reported by an LBT failure, and this application does not impose any restrictions on this.

[0223] In the above embodiment, the terminal device may also cancel the above layer 1 measurement reporting. For example, the terminal device cancels the layer 1 measurement reporting when at least one of the following conditions is met:

[0224] The count value and / or the timer value or the reference signal of the candidate cell or serving cell that meets the first condition is reconfigured (for example, by the RRC layer or a higher layer);

[0225] A MAC CE including the above-mentioned Layer 1 measurement report has been generated or successfully sent;

[0226] The MAC PDU containing the MAC CE for the layer 1 measurement report has been assembled or successfully sent.

[0227] Therefore, the terminal device cancels the layer 1 measurement report when at least one of the above conditions is met, which can achieve UE energy saving and reduce signaling overhead.

[0228] In an embodiment of the present application, as shown in FIG7 , the terminal device may optionally also start to evaluate whether the first condition is satisfied. In some embodiments, the terminal device may evaluate whether the first condition is satisfied when at least one of the following conditions is satisfied:

[0229] Receive RRC signaling;

[0230] When RRC signaling is received, and the RRC signaling configures or reconfigures the first condition, or when the RRC signaling enables or allows evaluation of the first condition;

[0231] When the switch is completed;

[0232] When the service area deteriorates;

[0233] When an instruction to start the evaluation is received from the network device;

[0234] After the downlink has been synchronized;

[0235] After the downlink and / or uplink have been synchronized.

[0236] For example, when the terminal device receives the above-mentioned RRC signaling, which is used to configure or reconfigure the above-mentioned first condition or enable or allow the evaluation of the above-mentioned first condition, the terminal device starts to evaluate whether the above-mentioned first condition is met.

[0237] For another example, when the handover is completed, if the RRC signaling provides the above-mentioned first condition or indication of the serving cell after the handover, the terminal device begins to evaluate whether the above-mentioned first condition is met.

[0238] For another example, when receiving a layer 1 or layer 2 indication from the network device for instructing the start of evaluation, the terminal device starts to evaluate whether the above-mentioned first condition is met.

[0239] For another example, when the downlink is synchronized, the terminal device starts to evaluate whether the first condition is met. This example applies to "early uplink synchronization on a candidate cell", for example, when the downlink is synchronized, the terminal device starts to evaluate whether the first condition for early uplink synchronization on a candidate cell is met.

[0240] For another example, after downlink and / or uplink synchronization, the terminal device begins to evaluate whether the above-mentioned first condition is met. This example is applicable to "LTM execution to the target cell", for example, after downlink and / or uplink synchronization, the terminal device begins to evaluate whether the above-mentioned first condition for LTM execution to the target cell is met.

[0241] In an embodiment of the present application, as shown in FIG7 , the terminal device may optionally stop evaluating whether the first condition is satisfied. In some embodiments, the terminal device may stop evaluating whether the first condition is satisfied when at least one of the following conditions is satisfied:

[0242] Receive RRC signaling;

[0243] When RRC signaling is received, and the RRC signaling releases or deactivates or does not allow or prohibit the first condition;

[0244] When the switch is completed;

[0245] When the service area becomes better;

[0246] When a failure is detected;

[0247] When failure recovery is initiated;

[0248] After the uplink has been synchronized.

[0249] For example, when the RRC signaling received by the terminal device is to release or deactivate or not allow or prohibit the first condition, the terminal device stops evaluating.

[0250] For another example, when the handover is completed, if the RRC signaling does not provide the conditions or indications of the serving cell after the handover, the terminal device stops the evaluation.

[0251] For another example, when the quality of the serving cell improves, the terminal device stops evaluating. The content related to the improvement of the quality of the serving cell has been explained above and will not be repeated here.

[0252] For another example, when the terminal device detects a failure, the terminal device notifies the evaluation. Here, the detected failure is, for example, RLF, HOF, consistency check failure, integrity check failure, etc., but the present application is not limited thereto.

[0253] For another example, when failure recovery is initiated, the terminal device stops evaluating. The failure recovery may be, for example, RRC link reestablishment, but the present application is not limited thereto.

[0254] For another example, when the uplink is synchronized, the terminal device stops evaluating. This example applies to "early uplink synchronization on a candidate cell." For example, when the uplink is synchronized, the terminal device stops evaluating whether the first condition is met. For example, the first condition is the first condition for the terminal device to perform early uplink synchronization on a candidate cell.

[0255] The above is an exemplary description of the method of the embodiment of the present application, but the present application is not limited thereto, and appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0256] According to the method of the above embodiment, when the conditions (first condition) based on layer 1 measurement or based on layer 3 measurement are met, the terminal device performs at least one of layer 1 measurement reporting, early uplink synchronization on the candidate cell, and LTM execution to the target cell, thereby realizing autonomous action and saving signaling overhead.

[0257] An embodiment of the present application also provides a configuration method, which is described from the side of the network device. This method is the network-side processing corresponding to the method of the aforementioned embodiment, and the same content will not be repeated.

[0258] FIG8 is a schematic diagram of a configuration method according to an embodiment of the present application. As shown in FIG8 , the method includes:

[0259] 810: The network device sends a first configuration to the terminal device, where the first configuration is related to a first condition based on layer 1 measurement or layer 3 measurement; the first condition is used to trigger the terminal device to perform at least one of the following processes: layer 1 measurement reporting, early uplink synchronization on the candidate cell, and LTM execution to the target cell.

[0260] In some embodiments, the first configuration is sent via RRC signaling, and the first condition based on layer 1 measurement is included in the first configuration.

[0261] In some embodiments, the first configuration is sent via RRC signaling, and the first condition based on layer 3 measurement is included in the first configuration.

[0262] In some embodiments, the first configuration is sent via RRC signaling, and the count value and / or timer value for the first condition is included in the first configuration.

[0263] In the above embodiment, the first configuration may further include indication information to indicate whether the above count value and / or timer value is allowed or enabled.

[0264] In some embodiments, the network device may further perform at least one of the following processes:

[0265] Receive L1 measurement report sent by terminal equipment (corresponding to layer 1 measurement report on the UE side);

[0266] Receive the preamble sent by the terminal device (corresponding to early uplink synchronization on the candidate cell);
