[0035] Embodiments of the present disclosure provide an information processing method and terminal, a communication device, a communication system, and a storage medium.

[0036] In a first aspect, an embodiment of the present disclosure provides an information processing method, wherein the method includes:

[0037] The terminal determines whether to perform layer L1 measurement related operations according to the cell measurement result of the terminal.

[0038] In the above embodiment, the terminal can determine whether to perform L1 measurement-related operations based on the cell measurement results. There is no need for the terminal to send the measurement results to the network device, nor is there a need to wait for the network device to send trigger signaling for controlling and changing the L1 measurement. Compared with the method in which the network device triggers the start of L1 measurement, the method shown in the embodiment of the present disclosure can effectively reduce the additional signaling overhead caused by the network device triggering the start of the L1 measurement method, reduce latency, and is more suitable for rapidly changing network environments.

[0039] In combination with some embodiments of the first aspect, in some embodiments, the measurement result of the L1 measurement is used to determine whether to perform a mobility operation LTM triggered by layer L1 or layer L2.

[0040] In the above embodiment, the measurement result of L1 measurement can assist the network device in determining the communication quality of the current serving cell of the terminal, thereby determining whether the terminal should perform LTM so that the terminal can adapt to the rapidly changing network environment.

[0041] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal determines whether to perform layer L1 measurement-related operations based on the cell measurement result of the terminal, including at least one of the following:

[0042] Determining whether to start L1 measurement according to the cell measurement result;

[0043] determining whether to stop L1 measurement according to the cell measurement result;

[0044] According to the cell measurement result, L1 measurement reporting is activated or deactivated.

[0045] In the above embodiment, the terminal can independently determine whether to initiate L1 measurement based on the cell measurement results. Alternatively, if the terminal is configured to periodically initiate L1 measurement, the terminal can independently determine whether to stop L1 measurement based on the cell measurement results. Alternatively, if transmission resources are limited, the terminal can independently determine whether to activate or deactivate L1 measurement reporting based on the cell measurement results. This eliminates the need for network device triggering, reduces the additional signaling overhead introduced by network device control, and reduces latency.

[0046] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal determines whether to perform layer L1 measurement-related operations based on the cell measurement result of the terminal, including one of the following:

[0047] The cell measurement result corresponding to the serving cell is less than or equal to the measurement threshold, and the terminal determines to start L1 measurement;

[0048] The cell measurement result corresponding to the serving cell is greater than the measurement threshold, and the terminal determines not to start L1 measurement;

[0049] The cell measurement result corresponding to the non-serving cell is less than or equal to the measurement threshold, and the terminal determines not to start L1 measurement;

[0050] The cell measurement result corresponding to the non-serving cell is greater than the measurement threshold, and the terminal determines to start L1 measurement.

[0051] In the above embodiment, the terminal may determine whether to start L1 measurement based on the comparison result of the cell measurement result of the serving cell and / or the cell measurement result of the non-serving cell with the measurement threshold value, so as to determine whether to start L1 measurement according to the signal quality of the current serving cell or the signal quality of the non-serving cell; in this way, when the signal quality of the current serving cell is good or the signal quality of the non-serving cell is poor, that is, when the terminal does not need to perform cell switching, L1 measurement is not started to reduce the measurement power consumption of the terminal.

[0052] In conjunction with some embodiments of the first aspect, in some embodiments, the non-serving cell includes at least one of the following:

[0053] One or more candidate primary cells (PCells) corresponding to the LTM configuration configured by the network device;

[0054] One or more candidate primary and secondary cells (PSCells) corresponding to the LTM configuration configured by the network device;

[0055] Neighboring cell corresponding to L1 measurement configured by the network device.

[0056] In the above embodiment, the terminal may determine the signal quality of the candidate cell based on the cell measurement results of one or more candidate cells (candidate primary cell PCell and / or candidate primary and secondary cell PSCell) configured by the LTM configured by the network device, and then determine whether to start L1 measurement. Alternatively, the terminal may determine the signal quality of the neighboring cell based on the cell measurement results of the neighboring cell corresponding to the L1 measurement configured by the network device, and then determine whether to start L1 measurement. In this way, when the signal quality of the candidate cell or the neighboring cell corresponding to the L1 measurement is poor, that is, when the terminal does not need to perform cell switching, L1 measurement is not started to reduce the measurement power consumption of the terminal.

[0057] In conjunction with some embodiments of the first aspect, in some embodiments, the measurement threshold value includes at least one of the following:

[0058] Measurement thresholds based on network device configuration;

[0059] The measurement threshold value agreed upon in the protocol;

[0060] A measurement threshold value is determined according to the measurement capability of the terminal.

[0061] In the above embodiment, the measurement threshold value can be configured by the network device, or can be a default value agreed upon by the protocol, or can be determined by the terminal according to its own measurement capability, thereby improving the flexibility of the measurement threshold value; and adjusting the triggering condition of the L1 measurement according to actual conditions.

[0062] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal determines whether to perform layer L1 measurement-related operations based on the cell measurement result of the terminal, including:

[0063] The terminal determines whether to start L1 measurement associated with the serving cell and / or non-serving cell according to the L3 measurement result of the serving cell.

[0064] In the above embodiment, the terminal can determine the communication quality of the serving cell based on the L3 measurement results of the serving cell, and determine whether it is necessary to start L1 measurement associated with the serving cell and / or non-serving cell based on the communication quality of the serving cell; there is no need for the network device to trigger the start of the L1 measurement, which reduces the additional signaling overhead introduced by the network device control and reduces the delay.

[0065] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal determines whether to perform layer L1 measurement-related operations based on the cell measurement result of the terminal, including:

[0066] The terminal determines whether to start L1 measurement associated with a non-serving cell according to the L1 measurement result and / or L3 measurement result of the serving cell.

[0067] In the above embodiment, when measuring the serving cell, L3 measurement can be performed on the serving cell, and L1 measurement can also be performed on the serving cell. Therefore, for scenarios with higher latency requirements, it can be determined more quickly whether it is necessary to start L1 measurement associated with non-serving cells based on the L1 measurement results of the serving cell, thereby reducing latency.

[0068] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal determines whether to perform layer L1 measurement-related operations based on the cell measurement result of the terminal, including:

[0069] The terminal determines whether to start L1 measurement associated with the non-serving cell according to the L3 measurement result of the non-serving cell.

[0070] In the above embodiment, the terminal can determine the communication quality of the non-service cell based on the L3 measurement result obtained by measuring the measurement reference signal of the non-service cell, and determine whether it is necessary to start the L1 measurement associated with the non-service cell based on the communication quality of the non-service cell; there is no need for the network device to trigger the start of the L1 measurement, which reduces the additional signaling overhead introduced by the network device control and reduces the delay.

[0071] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal determines whether to perform layer L1 measurement-related operations based on the cell measurement result of the terminal, including:

[0072] The terminal determines whether to start L1 measurement according to the L3 measurement results of the non-serving cell corresponding to one or more reference frequencies.

[0073] In the above embodiment, the terminal can determine the communication quality of the non-service cells corresponding to one or more reference frequencies based on the L3 measurement results obtained by measuring the measurement reference signals of the non-service cells corresponding to one or more reference frequencies, thereby determining whether it is necessary to start L1 measurement. On the one hand, the terminal does not need to send the measurement results to the network device, and the network device does not need to trigger the start of L1 measurement based on the measurement results, thereby reducing signaling overhead and latency; on the other hand, during the L3 measurement process, L3 measurement is only performed on the non-service cells corresponding to one or more reference frequencies, thereby reducing the number of non-service cells to be measured and reducing the power consumption of the terminal.

[0074] In combination with some embodiments of the first aspect, in some embodiments, the terminal determines whether to start L1 measurement associated with the serving cell and / or the non-serving cell based on the L3 measurement result of the serving cell, including at least one of the following:

[0075] Determine whether to start L1 measurement of the serving primary cell group MCG and / or the serving primary cell PCell according to the L3 measurement result of the serving primary cell PCell;

[0076] Determine whether to start L1 measurement of the terminal's candidate MCG and / or candidate PCell according to the L3 measurement result of the serving primary cell PCell;

[0077] Determine whether to start L1 measurement of non-serving cells based on the L3 measurement result of the serving primary cell (PCell), where the L1 measurement of the non-serving cells is associated with the configuration of the serving MCG and / or serving PCell;

[0078] Determine whether to start L1 measurement of the corresponding secondary cell group SCG and / or the serving primary and secondary cell PSCell according to the L3 measurement result of the serving primary and secondary cell PSCell;

[0079] Determine whether to start L1 measurement of the candidate SCG and / or candidate PSCell of the terminal according to the L3 measurement result of the serving primary and secondary cell PSCell;

[0080] According to the L3 measurement result of the serving primary and secondary cell PSCell, it is determined whether to start the L1 measurement of the non-serving cell, where the L1 measurement of the non-serving cell is associated with the configuration of the serving SCG and / or serving PSCell.

[0081] In the above embodiment, the terminal can determine whether there is a need for serving cell handover based on the L3 measurement results of the serving cell (i.e., PCell and / or PSCell) and the communication quality of the serving cell, thereby determining whether to initiate L1 measurement of the serving cell, candidate cells, and / or associated non-serving cells. In the process of determining whether to initiate L1 measurement, L3 measurement only needs to be performed on the serving cell. Based on the L3 measurement results of the serving cell, it is determined whether to initiate L1 measurement. There is no need to perform L3 measurement on all other non-serving cells, which effectively reduces the number of cells to be measured and reduces the power consumption of the terminal.

[0082] In combination with some embodiments of the first aspect, in some embodiments, the terminal determines whether to start the L1 measurement associated with the non-serving cell according to the L1 measurement result and / or L3 measurement result of the serving cell, including at least one of the following:

[0083] Determine whether to start L1 measurement of the candidate MCG and / or candidate PCell of the terminal according to the L1 measurement result and / or L3 measurement result of the serving primary cell PCell;

[0084] Determine whether to start L1 measurement of non-serving cells based on the L1 measurement result and / or L3 measurement result of the serving primary cell (PCell), where the L1 measurement of the non-serving cells is associated with the configuration of the serving MCG and / or serving PCell;

[0085] Determine whether to start L1 measurement of the candidate SCG and / or candidate PSCell of the terminal according to the L1 measurement result and / or L3 measurement result of the serving primary and secondary cell PSCell;

[0086] According to the L1 measurement result and / or L3 measurement result of the serving primary and secondary cell PSCell, it is determined whether to start the L1 measurement of the non-serving cell, where the L1 measurement of the non-serving cell is associated with the configuration of the serving SCG and / or serving PSCell.

[0087] In the above embodiment, the terminal can determine whether the terminal has a need to switch the service cell based on the L1 measurement results and / or L3 measurement results of the service cell (i.e., PCell and / or PSCell) and the communication quality of the service cell, thereby determining whether to start L1 measurement of the candidate cell and / or associated non-service cell. In the process of determining whether to start L1 measurement, on the one hand, only the service cell needs to be measured, and whether to start L1 measurement is determined based on the measurement results of the service cell. There is no need to measure other non-service cells, which effectively reduces the number of cells to be measured and reduces the power consumption of the terminal. On the other hand, when measuring the service cell, L3 measurement can be performed on the service cell, and L1 measurement can also be performed on the service cell. Therefore, for scenarios with higher latency requirements, it can be determined more quickly whether it is necessary to start L1 measurement of the candidate cell and / or associated non-service cell based on the L1 measurement results of the service cell, thereby reducing latency.

[0088] In conjunction with some embodiments of the first aspect, in some embodiments, the L1 measurement result and / or L3 measurement result of the serving cell includes at least one of the following:

[0089] an L3 measurement result of a measurement reference signal on the serving cell;

[0090] L3 measurement results of one or more beams of the serving cell;

[0091] an average of L3 measurement results of multiple beams of the serving cell;

[0092] an L1 measurement result of a measurement reference signal of the serving cell;

[0093] L1 measurement results of one or more beams of the serving cell;

[0094] The average of the L1 measurement results of multiple beams of the serving cell.

[0095] In the above embodiment, the terminal can monitor the measurement reference signal and / or one or more specific beams sent by the serving cell, and determine the communication quality of the serving cell based on the measurement results of the measurement reference signal and / or specific beams of the serving cell, thereby independently determining whether to initiate L1 measurement. This eliminates the need for the network device to trigger the initiation of L1 measurement, reducing the additional signaling overhead introduced by network device control and reducing latency. In addition, the terminal can monitor one or more specific beams of the serving cell to obtain measurement results of the one or more specific beams, eliminating the need to monitor all beams of the serving cell, thereby reducing the measurement power consumption of the terminal.

[0096] In conjunction with some embodiments of the first aspect, in some embodiments, the L3 measurement result of the non-serving cell includes at least one of the following:

[0097] L3 measurement results of measurement reference signals on non-serving cells;

[0098] L3 measurement results of one or more beams of the non-serving cell;

[0099] The average of the L3 measurement results of multiple beams of the non-serving cell.

[0100] In the above embodiment, the terminal can monitor the measurement reference signal and / or one or more specific beams sent by the non-serving cell, and determine the communication quality of the non-serving cell based on the measurement reference signal of the serving cell and / or the L3 measurement results of the specific beams, thereby independently determining whether to initiate L1 measurement. This eliminates the need for the network device to trigger the initiation of L1 measurement, reducing the additional signaling overhead introduced by network device control and reducing latency. Furthermore, the terminal can monitor one or more specific beams of the non-serving cell to obtain the L3 measurement results of the one or more specific beams, eliminating the need to monitor all beams of the non-serving cell.

[0101] In conjunction with some embodiments of the first aspect, in some embodiments, the one or more beams include at least one of the following:

[0102] One or more beams determined based on a network device configuration;

[0103] One or more beams agreed upon by the protocol.

[0104] In the above embodiment, the terminal can determine the specific beam for L3 measurement based on the configuration of the network device or the protocol agreement. On the one hand, it can improve the flexibility of the beam measurement. On the other hand, L3 measurement is performed only based on the specific beam. According to the L3 measurement result of the specific beam, it is determined whether to start L1 measurement, which can effectively reduce the measurement bandwidth of L3 measurement and reduce the power consumption of the terminal.

[0105] In conjunction with some embodiments of the first aspect, in some embodiments, the L1 measurement configuration of the non-serving cell includes at least one of the following:

[0106] a dedicated L1 measurement configuration configured by the network device for the non-serving cell;

[0107] L1 measurement configuration generated by the source MCG;

[0108] L1 measurement configuration generated by the source SCG.

[0109] In the above embodiment, when the terminal performs L1 measurement on the non-serving cell, the measurement can be performed based on the dedicated L1 measurement configuration configured by the network device for the non-serving cell, or the measurement can be performed by directly referring to the L1 measurement configuration generated by the source MCG or source SCG, thereby improving the flexibility of the L1 measurement of the non-serving cell.

[0110] With reference to some embodiments of the first aspect, in some embodiments, the measurement-related parameter of the L1 measurement is determined by the measurement-related parameter corresponding to the cell measurement result;

[0111] or,

[0112] The measurement-related parameters of the L1 measurement are determined by the L1 measurement configuration configured by the network device for the terminal;

[0113] or,

[0114] The measurement-related parameters of the L1 measurement are agreed upon by the protocol.

[0115] In the above embodiment, after determining to start L1 measurement, the terminal can determine the measurement-related parameters of the L1 measurement according to the measurement-related parameters corresponding to the cell measurement result that triggers the L1 measurement, the L1 measurement configuration configured by the network device for the terminal, and / or the protocol agreement, thereby improving the flexibility of the L1 measurement.

[0118] Based on measurements reported for triggering LTM;

[0119] Beam measurements based on one or more beams configured by the network device for performing LTM.

[0120] In the above embodiment, the terminal may perform L1 measurement based on one or more measurement configurations pre-configured for performing LTM, so as to use the L1 measurement results to assist the network device in performing LTM judgment; or, the terminal may perform other measurements that can trigger LTM measurement reporting, so as to use the measurement results to assist the network device in performing LTM judgment; or, the terminal may perform beam measurement based on one or more dedicated beams pre-configured, so as to use the beam measurement results to assist the network device in performing LTM judgment, thereby improving the flexibility of the initiated L1 measurement.

[0123] In the above embodiment, the terminal can perform RRM measurements on the serving cell and / or non-serving cell, and determine the communication quality of the serving cell and / or non-serving cell based on the measurement results of the RRM measurement used for mobility management, thereby determining whether to start L1 measurement based on the communication quality of the serving cell and / or non-serving cell. There is no need for the network device to trigger the start of L1 measurement, thereby reducing the additional signaling overhead introduced due to the control of the network device and reducing the delay.

[0156] As shown in FIG. 1 a , a communication system 100 includes a terminal 101 and a network device 102 .

[0157] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0173] In some embodiments, the information processing method shown in the embodiments of the present disclosure may be applied to a communication system using dual connectivity technology, which includes the following:

[0174] The first is Multi-Radio Dual Connectivity (MR-DC).

[0175] MR-DC is a generalized dual connectivity within the evolved universal terrestrial radio access (E-UTRA) of the UMTS. In this system, the UE can utilize radio resources provided by two different resource scheduling units located on two different next-generation radio access network (NG-RAN) nodes, connected via a non-ideal backhaul: one providing New Radio (NR) access and the other providing E-UTRA or NR access. The base station of the primary cell can be a master node (MN), and the base station of the secondary cell can be a secondary node (SN); the master node and the secondary node are connected via a network interface, with at least one of the master nodes connected to the core network.

[0176] The second type is MR-DC based on the Evolved Packet Core (EPC).

[0177] Refer to Figure 1b, which shows an architecture diagram of the Evolved Universal Terrestrial Radio Access Network (E-UTRA-NR) Dual Connectivity (EN-DC). E-UTRAN supports MR-DC through E-UTRA-NR Dual Connectivity (EN-DC), where the UE connects to an eNB (eNode B) acting as a master node (MN) and an en-gNB (en-gNB) acting as a secondary node (SN). The eNB connects to the EPC (Core Network) via the S1 interface and to the en-gNB via the X2 interface. The en-gNB can also connect to the EPC (Core Network) via the S1-U interface and to other en-gNBs via the X2-U interface.

[0178] The core network equipment of the EPC may include: a Mobility Management Entity (MME) and / or a Serving Gateway (S-GW).

[0179] The third type is the MR-DC of the fifth-generation mobile communication core network (5th Generation Core, 5GC).

[0180] 5GC supports the following dual connections:

[0181] 1) Evolved Universal Terrestrial Radio Access (E-UTRA) - New Radio (NR) and Next Generation RAN E-UTRA New Radio - Dual Connectivity (NGEN-DC) Dual Connectivity:

[0182] The 5G radio access network NG-RAN supports NG-RAN E-UTRA-NR dual connectivity (NGEN-DC), in which the UE is connected to the ng-eNB as the primary node (MN) and the gNB as the secondary node (SN). The base station ng-eNB is connected to the 5GC, and the base station gNB is connected to the base station ng-eNB through the Xn interface.

[0183] 2) Dual connectivity of the New Radio-Evolution Universal mobile telecommunications system Terrestrial Radio Access Network (NR-E-UTRA):

[0184] NG-RAN supports NR-E-UTRA Dual Connectivity (NE-DC), where the UE is connected to the gNB acting as the mobile node and the ng-eNB acting as the secondary node (SN). The gNB is connected to the 5GC, and the ng-eNB is connected to the gNB via the Xn interface.

[0185] 3) NR-NR dual connectivity:

[0186] Referring to Figure 1c, which is a schematic diagram of the NR-DC architecture, NG-RAN supports NR-NR Dual Connectivity (NR-DC), in which the UE is connected to a base station gNB acting as a mobile node and another base station gNB acting as a secondary node SN. The primary gNB is connected to the 5GC via the NG interface, and the two gNBs are connected via the Xn interface. The secondary gNB can also be connected to the 5GC via the NG-U interface. In addition, NR-DC can also be used for UEs to access a single base station gNB, which acts as both a mobile node and a secondary node SN, and is configured with a primary cell group (MCG) and a secondary cell group (SCG).

[0187] In some embodiments, under dual connectivity, a user equipment (UE) can access two cells or two cell groups at the same time. For example, accessing the primary cell (PCell) and the secondary cell (SCell) at the same time, or accessing the master cell group (MCG) and the secondary cell group (SCG) at the same time. The MCG includes multiple cells, one of which is used to initiate initial access, and this cell is called the PCell. As the name suggests, the PCell is the most important cell in the MCG. The other cells in the MCG except the PCell are SCells. The PCell in the MCG and the SCell in the MCG are combined through carrier aggregation (CA) to improve the transmission rate and meet the user's requirements for the rate.

[0188] In some embodiments, the primary cell in an MCG (Master Cell Group) can be abbreviated as PCell, and the secondary cell can be abbreviated as SCell. The primary and secondary cells in an SCG (Secondary Cell Group) can be abbreviated as PSCell. Typically, much of the UE's control signaling is sent only on the PCell or PSCell. In some embodiments, the concept of a special (Primary) cell (sPcell) is proposed; the sPcell may include: the PCell and / or the PSCell.

[0189] As shown in Figure 1d, Figure 1d is a schematic diagram of a primary cell group and a secondary cell group. When a UE supports dual connectivity, multi-connectivity, or carrier aggregation, the UE's serving cell may include a primary cell and a secondary cell; and the UE's serving cell group may include: a primary cell group and a secondary cell group.

[0190] L1 / L2-Triggered Mobility (LTM) was introduced in Release 18. In some embodiments, a network device may provide a terminal with multiple candidate cells or candidate cell groups. The network device may subsequently control the terminal to change between multiple candidate cells or cell groups through L1 signaling or L2 signaling, such as changing a candidate cell or candidate cell group from candidate cell or cell group-1 to candidate cell or cell group-2. L1 signaling may include downlink control information (DCI), and L2 signaling may include MAC control element (CE) signaling.

[0191] Among them, one serving cell or cell group may correspond to one or more candidate cells or cell groups.

[0192] In one embodiment, LTM is a process that may include: the gNB pre-transmitting an LTM configuration to the UE via RRC signaling; upon receiving a Layer 1 measurement report from the UE, the gNB, based on this, sends a handover command to change the UE's serving cell via MAC CE signaling. This cell handover command indicates LTM candidate configurations, which are one or more LTM candidate configurations pre-transmitted to the UE by the network via RRC signaling. When a cell handover is triggered, the UE switches to a candidate cell associated with the LTM candidate configuration as the target cell. LTM candidate configurations can be added, modified, and / or released by the network equipment via RRC signaling.

[0193] In some embodiments, LTM is a PCell (or PSCell) cell switch procedure that the network triggers via MAC CE based on L1 measurements.

[0194] In some embodiments, the LTM may include subsequent LTM (Subsequent LTM), wherein in the subsequent LTM cell switching procedure, the network device does not need to reconfigure candidate cells for the UE (Subsequent LTM cell switch procedures between candidate cells where the UE does not need to be reconfigured by the network in between).

[0195] In some embodiments, the LTM may be used to trigger a change of a PCell or MCG, and / or the LTM may be used to trigger a change of a PSCell or SCG, and / or the LTM may also be used to trigger a change of an SCell.

[0196] In some embodiments, LTM may also be triggered by the UE based on a condition, that is, the UE determines whether to execute LTM based on whether the condition is met.

[0197] As shown in Figure 1e, Figure 1e is a schematic diagram illustrating an LTM interaction process according to an exemplary embodiment. In LTM, the gNB pre-sends the candidate cell configuration for LTM to the UE via RRC signaling. When the gNB receives the L1 measurement report from the UE, it sends a cell handover command via MAC CE to change the UE's serving cell. The UE then triggers a cell handover by selecting the specified LTM candidate cell configuration as the gNB's target configuration. The LTM candidate cell configuration can only be added, modified, and released by the network via RRC signaling. The LTM process can be used to reduce mobility delay.

[0198] In one embodiment, the configuration of an LTM includes but is not limited to at least one of the following: a configuration identifier, and a configuration of a corresponding candidate target cell (or cell group).

[0199] The network side can configure multiple LTM configurations and reference configurations for the UE at the same time.

[0200] The configuration identifier is an ID indicating the relevant configuration.

[0201] The configuration of the corresponding candidate target cell (or cell group) is the candidate configuration corresponding to the target cell accessed when the UE triggers the mobility operation. This configuration can be represented by RRC reconfiguration (RRCReconfiguration).

[0202] The reference configuration is the reference configuration corresponding to the candidate target configuration. The candidate target configuration is an incremental configuration of the reference configuration. A complete configuration can be generated based on the candidate target configuration and the reference configuration. This configuration can be represented by an RRC reconfiguration. The UE applies the complete configuration when executing LTM. The reference configuration can be a specific configuration generated by the network or the UE's current configuration. Configurations specific to LTM require the reference configuration.

[0203] FIG1e is a schematic diagram of a LTM process according to an exemplary embodiment. As shown in FIG1e , the user needs to perform L1 measurement on each candidate cell and report the measurement result to the source cell to determine whether cell switching is required.

[0204] In Release 18 LTM, 3GPP has enhanced L1 measurement to support both intra-frequency and inter-frequency L1 measurements. In some embodiments, Release 18 only supports L1-RSRP measurement based on SSB.

[0205] In some embodiments, L1 measurements support semi-persistent and aperiodic reporting on the physical uplink shared channel (PUSCH) and semi-persistent and aperiodic reporting on the physical uplink control channel (PUCCH).

[0206] In some embodiments, the enhancement of L1 measurement may also have the following alternative options:

[0207] CSI-RS measurement;

[0208] L1-SINR measurement;

[0209] Event-triggered L1 measurement reporting;

[0210] Current L1 measurement enhancement.

[0211] FIG2a is an interactive diagram illustrating an information processing method according to an exemplary embodiment. As shown in FIG2a , the embodiment of the present disclosure relates to an information processing method for a communication system 100, the method comprising:

[0212] Step S2101: The network device sends first information to the terminal.

[0213] In some embodiments, the terminal receives first information sent by the network device.

[0214] In some embodiments, the terminal may be a terminal supporting dual connectivity, multiple connectivity or carrier aggregation.

[0215] In some embodiments, the terminal may be a terminal supporting L1 measurement.

[0216] In some embodiments, the terminal may be an LTM-capable terminal.

[0217] Exemplarily, supporting LTM may include supporting LTM for PCell or MCG, supporting LTM for PSCell or SCG, or supporting both.

[0218] In some embodiments, the network device may be an access network device corresponding to a serving cell or a source cell to which the terminal is currently accessing.

[0219] In some embodiments, the network device may be an access network device corresponding to a primary cell or a primary cell group of the terminal.

[0220] In some embodiments, the network device may be an access network device corresponding to a primary or secondary cell or a secondary cell group of the terminal.

[0221] In some embodiments, the first information may include: LTM configurations corresponding to one or more candidate cells.

[0222] In some embodiments, the LTM configuration may be an LTM configuration corresponding to a layer 1 (Layer 1, L1) or layer 2 (Layer 2, L2) triggered mobility LTM configured by the network device for the terminal.

[0223] In some embodiments, the L1 / L1-triggered mobility LTM may include at least one of the following:

[0224] L1 / L2 triggered mobility of primary cell group or primary cell;

[0225] L1 / L2 triggered mobility of the secondary cell group or primary and secondary cells.

[0226] In some embodiments, the mobility of the primary cell group or primary cell triggered by L1 / L2 is used to control the terminal to change its serving primary cell group or primary cell among multiple candidate primary cell groups or candidate primary cells corresponding to the terminal's serving primary cell group or primary cell.

[0227] In some embodiments, the mobility of the secondary cell group or primary and secondary cell triggered by L1 / L2 is used for the terminal to change its serving secondary cell group or primary and secondary cell among multiple candidate secondary cell groups or candidate primary and secondary cells corresponding to the terminal's serving secondary cell group or primary and secondary cell.

[0228] In some embodiments, the first information may include at least one of the following:

[0229] One or more configuration information identifiers;

[0230] One or more candidate cells or candidate cell group identifiers to be measured;

[0231] measurement configuration of one or more serving cells or serving cell groups;

[0232] measurement configuration of one or more candidate cells or candidate cell groups;

[0233] mobility configuration of one or more candidate cells;

[0234] One or more measurement thresholds.

[0235] In some embodiments, measuring the threshold value may include:

[0236] The threshold value corresponding to the L3 measurement result. It should be noted that whether to start L1 measurement is determined based on the comparison between the L3 measurement result of the serving cell and the threshold value. The L1 measurement includes but is not limited to: L1 measurement of the serving cell and / or non-serving cell.

[0237] In some embodiments, the measurement threshold value includes at least one of the following:

[0238] Measurement thresholds based on network device configuration;

[0239] The measurement threshold value agreed upon in the protocol;

[0240] The UE determines the measurement threshold based on its implementation.

[0241] It is understandable that the measurement threshold value may be configured by the network device, or the measurement threshold value may be a default value agreed upon by the protocol, or a threshold value determined by the UE based on implementation.

[0242] In some embodiments, different serving cells correspond to different measurement thresholds, for example, a serving PCell corresponds to one measurement threshold, and a serving PSCell corresponds to another measurement threshold.

[0243] Exemplarily, the threshold value corresponding to the serving PCell is used to determine whether to start L1 measurement of the serving cell and / or non-serving cell configured by the serving PCell (or serving MCG) for the UE.

[0244] Exemplarily, the threshold value corresponding to the serving PSCell is used to determine whether to start L1 measurement of the serving cell and / or non-serving cell configured by the serving PSCell (or serving SCG) for the UE.

[0245] In some embodiments, the measurement threshold value may be independently configured for different non-serving cells, or a universal measurement threshold value may be configured.

[0246] In some embodiments, the measurement threshold may be configured to initiate L1 measurement of the serving cell.

[0247] In some embodiments, the measurement quantities corresponding to the thresholds for starting L1 measurement of the serving cell and the non-serving cell may be the same or different. The measurement quantity may be at least one of RSRQ, RSRP, and SINR.

[0248] In some embodiments, the thresholds for initiating L1 measurement of the serving cell and the non-serving cell may be the same or different.

[0249] Exemplarily, for the independently configured threshold value, the network side configures threshold value #1 for non-serving cell 1, and the UE determines whether to start L1 measurement of non-serving cell 1 based on the comparison between the measurement result of the serving cell and threshold value #1.

[0250] Exemplarily, for the commonly configured threshold value, the network side configures a common threshold value #0 for all non-service cells configured with L1 measurement configuration. The UE determines whether to start L1 measurement of one or more non-service cells configured with L1 configuration by the network based on the comparison between the measurement result of the serving cell and the threshold value #0.

[0251] In some embodiments, the first information may be sent via signaling.

[0252] In some embodiments, the first information may be sent via L1 signaling.

[0253] In some embodiments, L1 signaling includes at least downlink control information (DCI).

[0254] In some embodiments, the first information may be sent via L2 signaling.

[0255] In some embodiments, L2 signaling includes at least: a Media Access Control (MAC) control element (CE), etc.

[0256] In some embodiments, the first information may be sent via L3 signaling.

[0257] In some embodiments, L3 signaling may include: Radio Resource Control (RRC) signaling.

[0258] Step S2102: The terminal performs mobility measurement on the serving cell.

[0259] In some embodiments, the terminal performs L3 measurements on the serving cell.

[0260] It is worth noting that the terminal can perform L3 measurement on the serving cell to determine the communication quality of the serving cell based on the measurement results of the L3 measurement of the serving cell. It is understandable that if the communication quality of the serving cell is good, the terminal does not need to perform cell handover, and on this basis, there is no need to perform L1 measurement for LTM.

[0261] In some embodiments, the terminal performs L3 measurement on the serving cell, which may include at least one of the following:

[0262] The terminal performs L3 measurement on the serving cell in the serving MCG;

[0263] The terminal performs L3 measurement on the serving cell in the serving SCG;

[0264] The terminal performs L3 measurements on the serving PCell;

[0265] The terminal performs L3 measurements on the serving PSCell.

[0266] In some embodiments, the terminal performs L3 measurement on the serving cell, which may include:

[0267] The terminal performs L3 measurement on the serving cell measurement object corresponding to the serving cell.

[0268] The serving cell may be one or more of a serving PCell, a serving PSCell, and a serving SCell.

[0269] It can be understood that the terminal in the embodiment of the present disclosure may be a terminal that supports dual connectivity, multi-connectivity or carrier aggregation, and the terminal can access two cells or two cell groups at the same time to improve the transmission rate. Therefore, the terminal performs L3 measurement on the serving cell, which may be performing L3 measurement on the MCG or PCell to which the terminal accesses to determine the communication quality of the MCG or PCell; or performing L3 measurement on the SCG or PSCell to which the terminal accesses to determine the communication quality of the SCG or PSCell. Based on the communication quality of the MCG or PCell, determine whether it is necessary to switch the MCG or PCell; based on the communication quality of the SCG or PSCell, determine whether it is necessary to switch the SCG or PSCell.

[0270] In some embodiments, L3 measurements may include Radio Resource Management (RRM) measurements.

[0271] In some embodiments, L3 measurements are used for mobility management of terminals.

[0272] It should be noted that mobility management refers to the process of managing terminal service continuity. It optimizes the connection between terminals and network devices, ensuring the availability of various network services and maintaining optimal network coverage or connectivity.

[0273] In some embodiments, the terminal may perform L3 measurement on the serving cell based on an L3 measurement configuration pre-configured by the network device.

[0274] In some embodiments, the L3 measurement configuration may include: measurement-related parameters of the L3 measurement.

[0275] In some embodiments, the measurement-related parameters of the L3 measurement may include at least one of the following:

[0276] Measuring reference signals;

[0277] measurement quantity;

[0278] Configuration information for measuring reference signals.

[0279] It should be noted that the measurement reference signal may be a reference signal periodically broadcast by a cell. A terminal may receive the measurement reference signal and determine the communication quality of the cell based on the signal strength of the measurement reference signal.

[0280] The measurement quantity may be a measurement value of a measurement reference signal determined by measurement; in some embodiments, the measurement quantity may be a parameter used to describe a performance indicator of the measurement reference signal. For example, the measurement quantity may be a channel quality indicator (CQI).

[0281] The configuration information of the measurement reference signal is used by the terminal to determine the signal resource of the measurement reference signal.

[0282] It can be understood that the terminal may receive the measurement reference signal according to the configuration information of the measurement reference signal, and perform measurement based on the received measurement reference signal to obtain a measurement value corresponding to the measurement reference signal.

[0283] In some embodiments, the configuration information for measuring reference signals may include at least one of the following:

[0284] identification of the measurement reference signal;

[0285] Resource configuration for measuring reference signals;

[0286] Period configuration of the measurement reference signal.

[0287] In some embodiments, the resource configuration of the sounding reference signal may be used to indicate the time-frequency resource location of the sounding reference signal.

[0288] It should be noted that the configuration information of the measurement reference signal is used by the terminal to monitor the measurement reference signal according to the configuration information of the measurement reference signal.

[0289] In some embodiments, measuring the reference signal may include at least one of the following:

[0290] Synchronization and system information block SSB;

[0291] Channel State Information-Reference Signal CSI-RS.

[0292] L3 measurement may be performed based on the SSB and / or CSI-RS of the serving cell to determine the L3 measurement result of the serving cell.

[0293] In some embodiments, the measurement quantity of the L3 measurement may include at least one of the following:

[0294] Reference Signal Receiving Power (RSRP);

[0295] Reference Signal Receiving Quality (RSRQ);

[0296] Reference signal to interference-plus-noise ratio (SINR).

[0297] It can be understood that the L3 measurement result of the serving cell may include: one or more of: L3-RSRP, L3-RSRQ, and L3-SINR.

[0298] Step S2103: The terminal determines whether to perform L1 measurement related operations.

[0299] In some embodiments, the terminal determines whether to perform L1 measurement-related operations based on the cell measurement result of the serving cell.

[0300] In some embodiments, the terminal determines whether to perform L1 measurement-related operations based on the cell measurement result of the serving cell, which may include at least one of the following:

[0301] Determine whether to start L1 measurement based on the cell measurement result of the serving cell;

[0302] Determine whether to stop L1 measurement based on the cell measurement result of the serving cell;

[0303] Activate or deactivate L1 measurement reporting based on the cell measurement results of the serving cell.

[0304] Because L1 measurement results are used by the network device to determine whether the terminal should perform LTM, if the serving cell's cell measurement results indicate good communication quality, even if the terminal performs and reports L1 measurements, the network device will not control the terminal to perform LTM. This allows the network device to determine whether to initiate L1 measurements based on the serving cell's cell measurement results, even if the terminal's own measurement capabilities are insufficient. This reduces unnecessary measurements and reduces the terminal's measurement power consumption.

[0305] Alternatively, when the terminal is configured to periodically start L1 measurement, the terminal may determine whether to stop L1 measurement according to the cell measurement result, so as to reduce the measurement power consumption of the terminal.

[0306] Alternatively, when transmission resources are limited, the terminal can determine whether to activate or deactivate L1 measurement reporting based on the cell measurement results, thereby effectively saving transmission resources. It should be noted that after completing the L1 measurement, the terminal can determine whether to report the L1 measurement results to the network device based on the cell measurement results. This can reduce unnecessary L1 measurement reporting when transmission resources are limited and the signal quality of the terminal's serving cell is good.

[0307] It is worth noting that the start and stop of L1 measurement and / or the activation and deactivation of L1 measurement reporting can be determined by the terminal without being triggered by the network device, thereby reducing the additional signaling overhead introduced by network device control and reducing latency.

[0308] In some embodiments, the L1 measurement may be a beam measurement.

[0309] It should be noted that in New Radio (NR), especially when the communication frequency band is in Frequency Range (FR) 2, due to the rapid attenuation of high-frequency channels, in order to ensure the coverage of the signal, terminals and network devices can send and receive information based on beams.

[0310] In some embodiments, a cell may include multiple beams.

[0311] In some embodiments, the measurement results of the L1 measurement may be used to determine the beam performance of one or more beams of the cell.

[0312] In some embodiments, the measurement result of the L1 measurement can be used to determine the serving beam for communication between the terminal and the network device from multiple beams in the cell.

[0313] In some embodiments, the measurement result of the L1 measurement is used to determine whether to perform a mobility operation LTM triggered by the layer L1 or the layer L2.

[0314] In some embodiments, the measurement result of L1 measurement is used to assist the network device in performing cell handover decision.

[0315] It should be noted that the terminal performs L1 measurement and reports the measurement results of the L1 measurement to the network device, so that the network device can determine the beam performance and / or cell performance of the cell based on the measurement results of the L1 measurement reported by the terminal, and then determine whether the terminal needs to perform cell switching; when it is determined that the terminal needs to perform cell switching, the service cell is changed through L1 or L2 signaling, and the corresponding service beam is selected to achieve rapid switching of the cell and achieve the purpose of low latency and low overhead.

[0316] In some embodiments, the L1 measurement includes at least one of the following:

[0317] L1 measurements based on one or more measurement configurations corresponding to the LTM configuration configured on the network device;

[0318] Based on measurements reported for triggering LTM;

[0319] Beam measurements based on one or more beams configured by the network device for performing LTM.

[0320] It is understandable that the network device may pre-configure the LTM configuration for the terminal; it should be noted that the LTM configuration is used by the terminal to perform mobility operations related to the LTM configuration.

[0321] In some embodiments, the LTM configuration may include at least one of the following:

[0322] One or more candidate cells configured by the network device for the terminal;

[0323] L1 measurement configuration, where the L1 measurement configuration may be a measurement configuration corresponding to one or more candidate cells.

[0324] In some embodiments, the L1 measurement configuration may not be included in the LTM configuration, but may be sent to the UE by the network side through other information, for example, together with the L3 measurement configuration, or separately. For example, the terminal may initiate L1 measurement based on one or more pre-configured measurement configurations for performing LTM, and report the L1 measurement results, so as to utilize the L1 measurement results to assist the network device in performing LTM decisions.

[0325] Exemplarily, the terminal may initiate L1 measurement based on one or more pre-configured measurement configurations for performing LTM, and trigger LTM-based cell change based on the L1 measurement result.

[0326] Alternatively, the terminal may perform other measurements that can trigger LTM measurement reporting, so as to use the measurement results to assist the network device in performing LTM decision.

[0327] Alternatively, the network device may be pre-configured with one or more dedicated beams, and the beam performance of the beam is used to assist the network device in determining whether the terminal needs to perform LTM.

[0328] The terminal can perform beam measurement based on one or more pre-configured dedicated beams, so as to use the beam measurement results to assist the network device in performing LTM decision.

[0329] Alternatively, this dedicated beam is determined by the UE based on implementation or protocol provisions, such as the best one or more beams in a cell, or one or more beams in a cell that are greater than a threshold configured by the network or a threshold agreed upon by the protocol.

[0330] It is worth noting that the terminal can determine whether to start any of the above measurements based on the cell measurement results, so as to assist the network device in performing LTM decision by reporting the measurement results to the network device, thereby improving the flexibility of the started L1 measurement.

[0331] In some embodiments, the terminal determines whether to perform L1 measurement-related operations based on the L3 measurement result of the serving cell.

[0332] The terminal can determine the communication quality of the serving cell based on the L3 measurement results obtained by measuring the measurement reference signal of the serving cell, and thus determine whether to start L1 measurement by itself. There is no need for the network device to trigger the start of L1 measurement, which reduces the additional signaling overhead introduced by network device control and reduces latency.

[0333] In some embodiments, the terminal determines whether to start L1 measurement based on the L3 measurement result of the serving cell, including at least one of the following:

[0334] Determine whether to start L1 measurement of the serving cell based on the L3 measurement result of the serving cell;

[0335] Determine whether to start L1 measurement associated with non-serving cells based on the L3 measurement result of the serving cell.

[0336] In some embodiments, determining whether to start L1 measurement of the serving cell is based on the L3 measurement result of the serving cell. This can be understood as determining whether to start beam measurement of multiple beams of the serving cell based on the L3 measurement result of the serving cell.

[0337] In some embodiments, whether to start L1 measurement of multiple beams of the serving cell may be determined based on the L3 measurement result of the serving beam of the serving cell.

[0338] In some embodiments, the measurement period of the L1 measurement of the serving cell is smaller than the measurement period of the L3 measurement of the serving cell.

[0339] It is worth noting that the measurement power consumption corresponding to the L3 measurement of the serving cell is less than the measurement power consumption corresponding to the L1 measurement of the serving cell. In this way, the terminal can determine whether to start the L1 measurement of the serving cell with greater measurement power consumption based on the L3 measurement result of the serving cell with lower measurement power consumption.

[0340] In some embodiments, determining whether to start L1 measurement associated with non-service cells is based on the L3 measurement results of the service cell. This can be understood as determining whether to start beam measurement associated with one or more non-service cells based on the L3 measurement results of the service cell.

[0341] It is worth noting that the terminal can determine the communication quality of the serving cell based on the L3 measurement result of the serving cell, and thus determine whether to start L1 measurement associated with the non-serving cell based on the communication quality of the serving cell.

[0342] In some embodiments, the serving cell may include: a PCell and / or a PSCell.

[0343] In some embodiments, the non-serving cell may include at least one of the following:

[0344] One or more candidate cells or candidate cell groups corresponding to the LTM configuration configured in the network device;

[0345] Neighboring cell corresponding to L1 measurement configured by the network device.

[0346] In yet other embodiments, the non-serving cell may include:

[0347] The network device corresponding to the serving cell is a candidate cell configured for the terminal;

[0348] The cell is configured with L1 measurement and / or measurement reporting configuration by the network device corresponding to the non-serving cell.

[0349] In some embodiments, the candidate cell may be at least one candidate cell or a candidate cell group configured by the network device for the terminal to perform LTM.

[0350] In some embodiments, the candidate cells may include at least one of the following:

[0351] Cells in the candidate MCG for performing LTM;

[0352] Candidate PCells for performing LTM;

[0353] cells in the candidate SCG for performing LTM;

[0354] Candidate PSCells for performing LTM.

[0355] In some embodiments, the candidate cell group may include at least one of the following:

[0356] Candidate MCGs for performing LTM;

[0357] Candidate SCGs for performing LTM.

[0358] In some embodiments, determining whether to initiate L1 measurement of the serving cell according to the L3 measurement result of the serving cell includes:

[0359] Determine whether to start L1 measurement of the serving primary cell group MCG and / or the serving primary cell PCell according to the L3 measurement result of the serving primary cell PCell;

[0360] According to the L3 measurement result of the serving primary and secondary cells PSCell, it is determined whether to start the L1 measurement of the corresponding secondary cell group SCG and / or the serving primary and secondary cells PSCell.

[0361] In some embodiments, determining whether to initiate L1 measurement associated with a non-serving cell based on an L3 measurement result of a serving cell includes:

[0362] Determine whether to start L1 measurement of the terminal's candidate MCG and / or candidate PCell based on the L3 measurement result of the serving primary cell PCell;

[0363] Determine whether to start L1 measurement of non-serving cells based on the L3 measurement result of the serving primary cell (PCell), where the L1 measurement of the non-serving cells is associated with the configuration of the serving MCG and / or serving PCell;

[0364] Determine whether to start L1 measurement of the terminal's candidate SCG and / or candidate PSCell based on the L3 measurement result of the serving primary and secondary cell (PSCell);

[0365] According to the L3 measurement result of the serving primary and secondary cell PSCell, it is determined whether to start the L1 measurement of the non-serving cell, where the L1 measurement of the non-serving cell is associated with the configuration of the serving SCG and / or serving PSCell.

[0366] It should be noted that the L1 measurement of the non-service cell is associated with the configuration of the service MCG and / or service PCell. It can be understood that the L1 measurement configuration of the L1 measurement of the non-service cell can refer to the L1 measurement configuration of the service MCG and / or service PCell.

[0367] The L1 measurement of the non-serving cell is associated with the configuration of the serving SCG and / or serving PSCell. It can be understood that the L1 measurement configuration of the L1 measurement of the non-serving cell can refer to the L1 measurement configuration of the serving SCG and / or serving PSCell.

[0368] In some embodiments, the L3 measurement result of the serving cell includes at least one of the following:

[0369] L3 measurement results of the measurement reference signal on the serving cell;

[0370] L3 measurement results of one or more beams of the serving cell;

[0371] The average of the L3 measurement results of multiple beams of the serving cell.

[0372] In some embodiments, the serving cell may include multiple different beams, and the measurement reference signals may be transmitted using the multiple different beams.

[0373] The terminal can receive measurement reference signals transmitted using multiple different beams, and determine the communication quality of the serving cell and the beam performance of multiple beams of the serving cell based on the L3 measurement results of the measurement reference signals transmitted using multiple different beams.

[0374] The L3 measurement results of one or more beams of the serving cell can be understood as, when the terminal performs L3 measurement of the serving cell, it can monitor one or more specific beams of the serving cell to obtain the L3 measurement results of one or more specific beams, thereby eliminating the need to monitor all beams of the serving cell and reducing the power consumption of the terminal.

[0375] In some embodiments, the one or more beams include at least one of the following:

[0376] One or more beams determined based on a network device configuration;

[0377] One or more beams agreed upon by the protocol.

[0378] It can be understood that one or more beams may be beams specified by the network device, or beams determined by the terminal according to criteria agreed upon in the protocol.

[0379] For example, the beam may be one or more beams with the best current performance, or one or more beams whose measurement results are greater than a specific value.

[0380] It is worth noting that when the terminal performs L3 measurement of the service cell, it can directly monitor the beams pre-configured by the network device and / or the beams agreed upon by the protocol to obtain the L3 measurement results of one or more specific beams of the service cell; thereby eliminating the need to monitor all beams of the service cell and reducing the power consumption of the terminal.

[0381] In some embodiments, the terminal may determine the target beam based on the first information sent by the network device.

[0382] In some embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the serving cell, including at least one of the following:

[0383] If the cell measurement result of the serving cell is less than or equal to the measurement threshold, the terminal determines to start L1 measurement;

[0384] The cell measurement result of the serving cell is greater than the measurement threshold, and the terminal determines not to start L1 measurement.

[0385] It should be noted that the measurement threshold value may be the minimum threshold value of the cell signal that meets the communication requirements of the terminal.

[0386] It can be understood that if the cell measurement result of the service cell is less than or equal to the measurement threshold value, it means that the communication quality of the service cell is poor and the terminal has a cell switching requirement; based on this, the terminal can start L1 measurement to report the L1 measurement result to the network device, assisting the network device to determine whether the terminal executes LTM and determine the target cell to be switched.

[0387] If the cell measurement result of the serving cell is greater than the measurement threshold, it indicates that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal may not start L1 measurement to reduce the measurement power consumption of the terminal.

[0388] In some other embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the serving cell, including at least one of the following:

[0389] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines to start L1 measurement;

[0390] The cell measurement result of the serving cell is greater than or equal to the measurement threshold, and the terminal determines not to start L1 measurement.

[0391] In some other embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the serving cell, including at least one of the following:

[0392] If the cell measurement result of the serving cell is greater than or equal to the measurement threshold, the terminal determines to start L1 measurement;

[0393] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines not to start L1 measurement.

[0394] It should be noted that the measurement threshold value may be the highest threshold value of the cell signal that meets the communication requirements of the terminal.

[0395] It can be understood that if the cell measurement result of the service cell is greater than or equal to the measurement threshold value, it means that the communication quality of the service cell is poor and the terminal has a cell switching requirement; based on this, the terminal can start L1 measurement to report the L1 measurement result to the network device, assisting the network device to determine whether the terminal executes LTM and determine the target cell to be switched.

[0396] The cell measurement result of the serving cell is less than the measurement threshold, indicating that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal may not start L1 measurement to reduce the measurement power consumption of the terminal.

[0397] In some other embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the serving cell, including at least one of the following:

[0398] If the cell measurement result of the serving cell is greater than the measurement threshold, the terminal determines to start L1 measurement;

[0399] The cell measurement result of the serving cell is less than or equal to the measurement threshold, and the terminal determines not to start L1 measurement.

[0400] In some embodiments, determining whether to stop L1 measurement according to the cell measurement result includes at least one of the following:

[0401] If the cell measurement result of the serving cell is less than or equal to the measurement threshold, the terminal determines not to stop L1 measurement;

[0402] The cell measurement result of the serving cell is greater than the measurement threshold, and the terminal determines to stop L1 measurement.

[0403] It should be noted that the measurement threshold value may be the minimum threshold value of the cell signal that meets the communication requirements.

[0404] It is understandable that if the cell measurement result of the serving cell is less than or equal to the measurement threshold, it means that the communication quality of the serving cell is poor and the terminal needs to switch cells. Based on this, the terminal needs to continue to maintain (periodic) L1 measurement in order to report the L1 measurement result to the network device.

[0405] The cell measurement result of the serving cell is greater than the measurement threshold, indicating that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal can stop L1 measurement to reduce the measurement power consumption of the terminal.

[0406] In some other embodiments, determining whether to stop L1 measurement according to the cell measurement result includes at least one of the following:

[0407] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines not to stop L1 measurement;

[0409] In some other embodiments, determining whether to stop L1 measurement according to the cell measurement result includes at least one of the following:

[0410] If the cell measurement result of the serving cell is greater than or equal to the measurement threshold, the terminal determines not to stop L1 measurement;

[0411] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines to stop L1 measurement.

[0412] It should be noted that the measurement threshold value may be the highest threshold value of the cell signal that meets the communication requirements.

[0413] It is understandable that if the cell measurement result of the serving cell is greater than or equal to the measurement threshold, it means that the communication quality of the serving cell is poor and the terminal needs to switch cells. Based on this, the terminal needs to continue to maintain (periodic) L1 measurement in order to report the L1 measurement result to the network device.

[0414] The cell measurement result of the serving cell is less than the measurement threshold, indicating that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal can stop L1 measurement to reduce the measurement power consumption of the terminal.

[0415] In some other embodiments, determining whether to stop L1 measurement according to the cell measurement result includes at least one of the following:

[0416] The cell measurement result of the serving cell is greater than the measurement threshold, and the terminal determines not to stop L1 measurement;

[0417] If the cell measurement result of the serving cell is less than or equal to the measurement threshold, the terminal determines to stop L1 measurement.

[0418] In some embodiments, determining to activate or deactivate L1 measurement reporting based on the cell measurement result includes at least one of the following:

[0419] If the cell measurement result of the serving cell is less than or equal to the measurement threshold, the terminal determines to activate L1 measurement reporting;

[0420] The cell measurement result of the serving cell is greater than the measurement threshold, and the terminal determines to deactivate L1 measurement reporting.

[0421] It should be noted that the measurement threshold value may be the minimum threshold value of the cell signal that meets the communication requirements.

[0422] It can be understood that the cell measurement result of the serving cell is less than or equal to the measurement threshold value, indicating that the communication quality of the serving cell is poor and the terminal has a cell switching requirement; based on this, the terminal activates L1 measurement reporting so that the network device determines whether the terminal executes LTM and determines the target cell to be switched based on the L1 measurement result reported by the terminal.

[0423] The cell measurement result of the serving cell is greater than the measurement threshold, indicating that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal can deactivate L1 measurement reporting to reduce the occupation of transmission resources.

[0424] In some other embodiments, determining to activate or deactivate L1 measurement reporting according to the cell measurement result includes at least one of the following:

[0425] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines to activate L1 measurement reporting;

[0426] If the cell measurement result of the serving cell is greater than or equal to the measurement threshold, the terminal determines to deactivate L1 measurement reporting.

[0427] In some other embodiments, determining to activate or deactivate L1 measurement reporting according to the cell measurement result includes at least one of the following:

[0428] If the cell measurement result of the serving cell is greater than or equal to the measurement threshold, the terminal determines to activate L1 measurement reporting;

[0429] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines to deactivate L1 measurement reporting.

[0430] It should be noted that the measurement threshold value may be the highest threshold value of the cell signal that meets the communication requirements.

[0431] It can be understood that if the cell measurement result of the service cell is greater than or equal to the measurement threshold value, it means that the communication quality of the service cell is poor and the terminal has a cell switching requirement; based on this, the terminal activates L1 measurement reporting so that the network device determines whether the terminal executes LTM and determines the target cell to be switched based on the L1 measurement result reported by the terminal.

[0432] The cell measurement result of the serving cell is less than the measurement threshold, indicating that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal can deactivate L1 measurement reporting to reduce the occupation of transmission resources.

[0433] In some other embodiments, determining to activate or deactivate L1 measurement reporting according to the cell measurement result includes at least one of the following:

[0434] The cell measurement result of the serving cell is greater than the measurement threshold, and the terminal determines to activate L1 measurement reporting;

[0435] The cell measurement result of the serving cell is less than or equal to the measurement threshold, and the terminal determines to deactivate L1 measurement reporting.

[0436] In some embodiments, the measurement threshold value includes at least one of the following:

[0437] Measurement thresholds based on network device configuration;

[0438] The measurement threshold value agreed upon in the protocol;

[0439] The measurement threshold is determined based on the measurement capability of the terminal.

[0440] It is understandable that the measurement threshold value may be configured by the network device, or may be a default value agreed upon by the protocol.

[0441] In some embodiments, the measurement capabilities of the terminal may include at least one of the following:

[0442] The maximum number of measurement frequencies supported by the terminal;

[0443] The number of frequencies that the terminal can currently measure.

[0444] It is understandable that the terminal can determine the measurement threshold value on its own according to its own measurement capability, thereby performing L1 measurement within the scope of its own measurement capability.

[0445] In some embodiments, after determining to start the L1 measurement, the L1 measurement is performed according to measurement-related parameters of the L1 measurement.

[0446] In some embodiments, the measurement-related parameters of the L1 measurement may include at least one of the following:

[0447] Measuring reference signals;

[0448] measurement quantity;

[0449] Configuration information for measuring reference signals.

[0450] It should be noted that the measurement reference signal may be a reference signal periodically broadcast by a cell. A terminal may receive the measurement reference signal and determine the communication quality of the cell based on the signal strength of the measurement reference signal.

[0451] The measurement quantity may be a measurement value of a measurement reference signal determined by measurement; in some embodiments, the measurement quantity may be a parameter used to describe a performance indicator of the measurement reference signal. For example, the measurement quantity may be a channel quality indicator (CQI).

[0452] The configuration information of the measurement reference signal is used by the terminal to determine the signal resource of the measurement reference signal.

[0453] It can be understood that the terminal may receive the measurement reference signal according to the configuration information of the measurement reference signal, and perform measurement based on the received measurement reference signal to obtain a measurement value corresponding to the measurement reference signal.

[0454] In some embodiments, the configuration information for measuring reference signals may include at least one of the following:

[0455] identification of the measurement reference signal;

[0456] Resource configuration for measuring reference signals;

[0457] Period configuration of the measurement reference signal.

[0458] In some embodiments, the resource configuration of the sounding reference signal may be used to indicate the time-frequency resource location of the sounding reference signal.

[0459] It should be noted that the configuration information of the measurement reference signal is used by the terminal to monitor the measurement reference signal according to the configuration information of the measurement reference signal.

[0460] In some embodiments, measuring the reference signal may include at least one of the following:

[0461] Synchronization and system information block SSB;

[0462] Channel State Information-Reference Signal CSI-RS.

[0463] In some embodiments, the measurement quantity of L1 measurement may include at least one of the following:

[0464] Reference Signal Receiving Power (RSRP);

[0465] Reference Signal Receiving Quality (RSRQ);

[0466] Reference signal to interference-plus-noise ratio (SINR).

[0467] In some embodiments, the measurement-related parameters of the L1 measurement are determined by the measurement-related parameters corresponding to the cell measurement result;

[0468] or,

[0469] The measurement-related parameters of L1 measurement are determined by the L1 measurement configuration configured by the network device for the terminal;

[0470] or,

[0471] The measurement-related parameters of L1 measurement are agreed upon by the protocol.

[0472] It should be noted that the measurement-related parameters for the L1 measurement are determined by the measurement-related parameters corresponding to the cell measurement result. It can be understood that the measurement-related parameters for the L1 measurement initiated by the terminal are the same as the measurement-related parameters for the L3 measurement performed by the terminal on the serving cell. For example, the terminal may perform L3 measurement on the SSB for the serving cell and determine whether to initiate L1 measurement based on the L3-RSRP of the SSB. If the decision to initiate L1 measurement is made, L1 measurement may be performed on the SSBs of the serving cell and / or non-serving cells to obtain the L1-RSRP of the serving cell and / or non-serving cells.

[0473] In some embodiments, the measurement-related parameters of the L1 measurement initiated by the terminal may be different from the measurement-related parameters of the L3 measurement performed by the terminal on the serving cell.

[0474] For example, the terminal may perform L3 measurement on the SSB for the serving cell, and determine whether to start L1 measurement based on the L3-RSRP of the SSB; if it is determined to start L1 measurement, L1 measurement may be performed on the CSI-RS of the serving cell and / or non-serving cell to obtain the L1-SINR of the serving cell and / or non-serving cell.

[0475] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0476] In some embodiments, the term "send" can be interchanged with terms such as "transmit", "report", and "transmit".

[0477] The information processing method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2103. For example, step S2101 can be implemented as an independent embodiment, and step S2101 combined with step S2103 can be implemented as an independent embodiment, but is not limited thereto.

[0478] In some embodiments, steps S2102 and S2103 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that the terminal may perform L1 measurement on all candidate cells preconfigured by the network device for performing LTM, and the terminal does not need to determine whether to initiate L1 measurement based on the cell measurement results.

[0479] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that the initiation or change of L1 measurement may be controlled by the network device, that is, the network device triggers the terminal to initiate L1 measurement by sending trigger signaling, without the terminal performing cell measurement, and determines whether to initiate L1 measurement based on the cell measurement results.

[0480] FIG2b is an interactive diagram illustrating an information processing method according to an exemplary embodiment. As shown in FIG2b , the embodiment of the present disclosure relates to an information processing method for a communication system 100, the method comprising:

[0481] Step S2201: The network device sends first information to the terminal.

[0482] In some embodiments, the terminal receives first information sent by the network device.

[0483] In some embodiments, the terminal may be a terminal supporting dual connectivity, multiple connectivity or carrier aggregation.

[0484] In some embodiments, the terminal may be a terminal supporting L1 measurement.

[0485] In some embodiments, the terminal may be an LTM-capable terminal.

[0486] Exemplarily, supporting LTM may include supporting LTM for PCell or MCG, supporting LTM for PSCell or SCG, or supporting both.

[0487] In some embodiments, the network device may be an access network device corresponding to a serving cell or a source cell to which the terminal is currently accessing.

[0488] In some embodiments, the network device may be an access network device corresponding to a primary cell or a primary cell group of the terminal.

[0489] In some embodiments, the network device may be an access network device corresponding to a primary or secondary cell or a secondary cell group of the terminal.

[0490] In some embodiments, the first information may include: LTM configurations corresponding to one or more candidate cells.

[0491] In some embodiments, the LTM configuration may be an LTM configuration corresponding to a layer 1 (Layer 1, L1) or layer 2 (Layer 2, L2) triggered mobility LTM configured by the network device for the terminal.

[0492] In some embodiments, the L1 / L1-triggered mobility LTM may include at least one of the following:

[0493] L1 / L2 triggered mobility of primary cell group or primary cell;

[0494] L1 / L2 triggered mobility of the secondary cell group or primary and secondary cells.

[0495] In some embodiments, the mobility of the primary cell group or primary cell triggered by L1 / L2 is used to control the terminal to change its serving primary cell group or primary cell among multiple candidate primary cell groups or candidate primary cells corresponding to the terminal's serving primary cell group or primary cell.

[0496] In some embodiments, the mobility of the secondary cell group or primary and secondary cell triggered by L1 / L2 is used for the terminal to change its serving secondary cell group or primary and secondary cell among multiple candidate secondary cell groups or candidate primary and secondary cells corresponding to the terminal's serving secondary cell group or primary and secondary cell.

[0497] In some embodiments, the first information may include at least one of the following:

[0498] One or more configuration information identifiers;

[0499] One or more candidate cells or candidate cell group identifiers to be measured;

[0500] measurement configuration of one or more serving cells or serving cell groups;

[0501] measurement configuration of one or more candidate cells or candidate cell groups;

[0502] mobility configuration of one or more candidate cells;

[0503] One or more measurement thresholds.

[0504] In some embodiments, the measurement threshold value may include at least one of the following:

[0505] a first threshold value corresponding to the L1 measurement result;

[0506] The second threshold corresponding to the L3 measurement result.

[0507] It should be noted that whether to initiate L1 measurement is determined based on a comparison result between the L1 measurement result of the serving cell and the first threshold; and / or whether to initiate L1 measurement is determined based on a comparison result between the L3 measurement result of the serving cell and the second threshold. The L1 measurement includes but is not limited to: L1 measurement of non-serving cells.

[0508] Exemplarily, if the terminal determines whether to start L1 measurement of a non-serving cell based on the L1 measurement result of the serving cell, the network device may configure a first threshold value for the terminal.

[0509] If the terminal determines whether to start L1 measurement of a non-serving cell based on the L3 measurement result of the serving cell, the network device may configure a second threshold value for the terminal.

[0510] In some embodiments, the measurement threshold value includes at least one of the following:

[0511] Measurement thresholds based on network device configuration;

[0512] The measurement threshold value agreed upon in the protocol;

[0513] The threshold value is determined by the UE based on implementation.

[0514] It is understandable that the measurement threshold value may be configured by the network device, or the measurement threshold value may be a default value agreed upon by the protocol, or a threshold value determined by the UE based on implementation.

[0515] In some embodiments, the first threshold corresponding to the L1 measurement result and the second threshold corresponding to the L3 measurement result may be the same or different.

[0516] In some embodiments, the measurement quantity corresponding to the first threshold value and the measurement quantity corresponding to the second threshold value may be the same or different. The measurement quantity may be at least one of RSRQ, RSRP, and SINR.

[0517] In some embodiments, the measurement threshold may be configured to initiate L1 measurement for non-serving cells.

[0518] In some embodiments, different serving cells correspond to different measurement thresholds, for example, a serving PCell corresponds to one measurement threshold, and a serving PSCell corresponds to another measurement threshold.

[0519] Exemplarily, the threshold value corresponding to the serving PCell is used to determine whether to start L1 measurement of the non-serving cell configured by the serving PCell (or serving MCG) for the UE.

[0520] Exemplarily, the threshold value corresponding to the serving PSCell is used to determine whether to start the serving PSCell (or serving SCG) to configure L1 measurement of non-serving cells for the UE.

[0521] In some embodiments, the measurement threshold value may be independently configured for different non-serving cells, or a universal measurement threshold value may be configured.

[0522] In some embodiments, the thresholds for initiating L1 measurements of different non-serving cells may be the same or different.

[0523] In some embodiments, the measurement quantities corresponding to the thresholds for initiating L1 measurements of different non-serving cells may be the same or different, wherein the measurement quantity may be at least one of RSRQ, RSRP, and SINR.

[0524] For example, for independently configured thresholds, the network side configures threshold #1 for non-serving cell 1, and the UE determines whether to start L1 measurement of non-serving cell 1 based on a comparison between the measurement result of the serving cell and threshold #1.

[0525] Exemplarily, for the commonly configured threshold value, the network side configures a common threshold value #0 for all non-service cells #1 configured with L1 measurement configuration. The UE determines whether to start L1 measurement of one or more non-service cells configured with L1 configuration by the network based on the comparison between the measurement result of the serving cell and the threshold value #0.

[0526] Step S2202: The terminal performs mobility measurement on the serving cell.

[0527] In some embodiments, the terminal performs mobility measurement on the serving cell, which may include at least one of the following:

[0528] The terminal performs L1 measurement on the serving cell;

[0529] The terminal performs L3 measurement on the serving cell.

[0530] It should be noted that L1 measurement is based on Layer 1 (physical layer) measurement and does not require filtering at Layer 3 (network layer). Compared to L3 measurement, L1 measurement and reporting time is shorter.

[0531] It is worth noting that the terminal may perform L3 measurement and / or L1 measurement on the serving cell to determine the communication quality of the serving cell based on the L3 measurement and / or the measurement results of the L3 measurement of the serving cell. It is understandable that if the communication quality of the serving cell is good, the terminal does not need to perform cell handover, and on this basis, there is no need to perform L1 measurement for LTM.

[0532] In some embodiments, the terminal performs L1 measurement on the serving cell, which may include at least one of the following:

[0533] The terminal performs L1 measurement on the serving cell in the serving MCG;

[0534] The terminal performs L1 measurement on the serving cell in the serving SCG;

[0535] The terminal performs L1 measurements on the serving PCell;

[0536] The terminal performs L1 measurements on the serving PSCell.

[0537] In some embodiments, the terminal performs L1 measurement on the serving cell, which may include:

[0538] The terminal performs L1 measurement on the serving cell measurement object corresponding to the serving cell.

[0539] The serving cell may be one or more of a serving PCell, a serving PSCell, and a serving SCell.

[0540] It can be understood that the terminal in the embodiment of the present disclosure may be a terminal that supports dual connectivity, multi-connectivity or carrier aggregation, and the terminal can access two cells or two cell groups at the same time to improve the transmission rate. Therefore, the terminal performs L1 measurement on the serving cell, which may be performing L1 measurement on the MCG or PCell to which the terminal accesses to determine the communication quality of the MCG or PCell; or performing L1 measurement on the SCG or PSCell to which the terminal accesses to determine the communication quality of the SCG or PSCell. Based on the communication quality of the MCG or PCell, determine whether it is necessary to switch the MCG or PCell; based on the communication quality of the SCG or PSCell, determine whether it is necessary to switch the SCG or PSCell.

[0541] In some embodiments, the terminal performs L3 measurement on the serving cell, which may include at least one of the following:

[0542] The terminal performs L3 measurement on the serving cell in the serving MCG;

[0543] The terminal performs L3 measurement on the serving cell in the serving SCG;

[0544] The terminal performs L3 measurements on the serving PCell;

[0545] The terminal performs L3 measurements on the serving PSCell.

[0546] In some embodiments, the terminal performs L3 measurement on the serving cell, which may include:

[0547] The terminal performs L3 measurement on the serving cell measurement object corresponding to the serving cell.

[0548] The serving cell may be one or more of a serving PCell, a serving PSCell, and a serving SCell.

[0549] It can be understood that the terminal in the embodiment of the present disclosure may be a terminal that supports dual connectivity, multi-connectivity or carrier aggregation, and the terminal can access two cells or two cell groups at the same time to improve the transmission rate. Therefore, the terminal performs L3 measurement on the serving cell, which may be performing L3 measurement on the MCG or PCell to which the terminal accesses to determine the communication quality of the MCG or PCell; or performing L3 measurement on the SCG or PSCell to which the terminal accesses to determine the communication quality of the SCG or PSCell. Based on the communication quality of the MCG or PCell, determine whether it is necessary to switch the MCG or PCell; based on the communication quality of the SCG or PSCell, determine whether it is necessary to switch the SCG or PSCell.

[0550] In some embodiments, L3 measurements may include Radio Resource Management (RRM) measurements.

[0551] In some embodiments, L3 measurements are used for mobility management of terminals.

[0552] It should be noted that mobility management refers to the process of managing terminal service continuity. It optimizes the connection between terminals and network devices, ensuring the availability of various network services and maintaining optimal network coverage or connectivity.

[0553] In some embodiments, the terminal may perform L3 measurement on the serving cell based on an L3 measurement configuration pre-configured by the network device.

[0554] In some embodiments, the terminal may perform L1 measurement on the serving cell based on the L1 measurement configuration pre-configured by the network device.

[0555] In some embodiments, the L1 measurement configuration may include: measurement-related parameters of the L1 measurement.

[0556] In some embodiments, the L3 measurement configuration may include: measurement-related parameters of the L3 measurement.

[0557] In some embodiments, the measurement-related parameters of the L1 measurement or the L3 measurement may include at least one of the following:

[0558] Measuring reference signals;

[0559] measurement quantity;

[0560] Configuration information for measuring reference signals.

[0561] In some embodiments, the configuration information for measuring reference signals may include at least one of the following:

[0562] identification of the measurement reference signal;

[0563] Resource configuration for measuring reference signals;

[0564] Period configuration of the measurement reference signal.

[0565] In some embodiments, the resource configuration of the sounding reference signal may be used to indicate the time-frequency resource location of the sounding reference signal.

[0566] It should be noted that the configuration information of the measurement reference signal is used by the terminal to monitor the measurement reference signal according to the configuration information of the measurement reference signal.

[0567] In some embodiments, measuring the reference signal may include at least one of the following:

[0568] Synchronization and system information block SSB;

[0569] Channel State Information-Reference Signal CSI-RS.

[0570] L1 measurement and / or L3 measurement may be performed based on the SSB and / or CSI-RS of the serving cell to determine measurement results of the L1 measurement and / or L3 measurement of the serving cell.

[0571] In some embodiments, the measurement quantity may include at least one of the following:

[0572] Reference Signal Receiving Power (RSRP);

[0573] Reference Signal Receiving Quality (RSRQ);

[0574] Reference signal to interference-plus-noise ratio (SINR).

[0575] It is understood that the L1 measurement result of the serving cell may include: one or more of L1-RSRP, L1-RSRQ, and L1-SINR. The L3 measurement result of the serving cell may include: one or more of L3-RSRP, L3-RSRQ, and L3-SINR.

[0576] Step S2203: The terminal determines whether to perform L1 measurement related operations.

[0577] In some embodiments, the terminal determines whether to perform L1 measurement-related operations based on the cell measurement result of the serving cell.

[0578] In some embodiments, the terminal determines whether to perform L1 measurement-related operations associated with a non-serving cell based on the cell measurement result of the serving cell.

[0579] It is worth noting that the terminal can determine the communication quality of the serving cell based on the cell measurement result of the serving cell, and thus determine whether to perform L1 measurement-related operations associated with the non-serving cell based on the communication quality of the serving cell.

[0580] In some embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the serving cell, which may include at least one of the following:

[0581] Determine whether to start L1 measurement based on the cell measurement result of the serving cell;

[0582] Determine whether to stop L1 measurement based on the cell measurement result of the serving cell;

[0583] Activate or deactivate L1 measurement reporting based on the cell measurement results of the serving cell.

[0584] Because L1 measurement results are used by network equipment to determine whether a terminal should execute LTM, if the serving cell's cell measurement results indicate good communication quality, even if the terminal performs and reports L1 measurements, it may not execute LTM. This way, if a terminal's own measurement capabilities are insufficient, the decision to initiate L1 measurements can be made based on the serving cell's cell measurement results. This reduces unnecessary measurements and lowers the terminal's measurement power consumption.

[0585] Alternatively, when the terminal is configured to periodically start L1 measurement, the terminal may determine whether to stop L1 measurement according to the cell measurement result, so as to reduce the measurement power consumption of the terminal.

[0586] Alternatively, when transmission resources are limited, the terminal can determine whether to activate or deactivate L1 measurement reporting based on the cell measurement results, thereby effectively saving transmission resources. It should be noted that after completing the L1 measurement, the terminal can determine whether to report the L1 measurement results to the network device based on the cell measurement results. This can reduce unnecessary L1 measurement reporting when transmission resources are limited and the signal quality of the terminal's serving cell is good.

[0587] It is worth noting that the start and stop of L1 measurement and / or the activation and deactivation of L1 measurement reporting can be determined by the terminal without being triggered by the network device, thereby reducing the additional signaling overhead introduced by network device control and reducing latency.

[0588] In some embodiments, the L1 measurement may be a beam measurement.

[0589] It should be noted that in New Radio (NR), especially when the communication frequency band is in Frequency Range (FR) 2, due to the rapid attenuation of high-frequency channels, in order to ensure the coverage of the signal, terminals and network devices can send and receive information based on beams.

[0590] In some embodiments, a cell may include multiple beams.

[0591] In some embodiments, the measurement results of the L1 measurement may be used to determine the beam performance of one or more beams of the non-serving cell.

[0592] In some embodiments, the measurement result of the L1 measurement can be used to determine the serving beam for communication between the terminal and the network device from multiple beams of non-serving cells.

[0593] In some embodiments, the measurement result of the L1 measurement is used to determine whether to perform a mobility operation LTM triggered by the layer L1 or the layer L2.

[0594] In some embodiments, the measurement result of L1 measurement is used to assist the network device in performing cell handover decision.

[0595] It should be noted that the terminal performs L1 measurement and reports the measurement results of the L1 measurement to the network device, so that the network device can determine the beam performance and / or cell performance of the cell based on the measurement results of the L1 measurement reported by the terminal, and then determine whether the terminal needs to perform cell switching; when it is determined that the terminal needs to perform cell switching, the service cell is changed through L1 or L2 signaling, and the corresponding service beam is selected to achieve rapid switching of the cell and achieve the purpose of low latency and low overhead.

[0596] In some embodiments, the L1 measurement includes at least one of the following:

[0597] L1 measurements based on one or more measurement configurations corresponding to the LTM configuration configured on the network device;

[0598] Based on measurements reported for triggering LTM;

[0599] Beam measurements based on one or more beams configured by the network device for performing LTM.

[0600] It is understandable that the network device may pre-configure the LTM configuration for the terminal; it should be noted that the LTM configuration is used by the terminal to perform mobility operations related to the LTM configuration.

[0601] In some embodiments, the LTM configuration may include at least one of the following:

[0602] One or more candidate cells configured by the network device for the terminal;

[0603] L1 measurement configuration, where the L1 measurement configuration may be a measurement configuration corresponding to one or more candidate cells.

[0604] In some embodiments, the L1 measurement configuration may not be included in the LTM configuration, and may be sent to the UE by the network side through other information, for example, it may be sent to the UE together with the L3 measurement configuration, or it may be sent to the UE separately.

[0605] Exemplarily, the terminal may initiate L1 measurement based on one or more pre-configured measurement configurations for performing LTM, and report the measurement result of the L1 measurement, so as to assist the network device in performing LTM decision using the L1 measurement result.

[0606] Exemplarily, the terminal may initiate L1 measurement based on one or more pre-configured measurement configurations for performing LTM, and trigger LTM-based cell change based on the L1 measurement result.

[0607] Alternatively, the terminal may perform other measurements that can trigger LTM measurement reporting, so as to use the measurement results to assist the network device in performing LTM decision.

[0608] Alternatively, the network device may be pre-configured with one or more dedicated beams, and the beam performance of the beam is used to assist the network device in determining whether the terminal needs to perform LTM.

[0609] The terminal can perform beam measurement based on one or more pre-configured dedicated beams, so as to use the beam measurement results to assist the network device in performing LTM decision.

[0610] Alternatively, this dedicated beam is determined by the UE based on implementation or protocol provisions, such as the best one or more beams in a cell, or one or more beams in a cell that are greater than a threshold configured by the network or a threshold agreed upon by the protocol.

[0611] It is worth noting that the terminal can determine whether to start any of the above measurements based on the cell measurement results, so as to assist the network device in performing LTM decision by reporting the measurement results to the network device, thereby improving the flexibility of the started L1 measurement.

[0612] In some embodiments, the terminal determines whether to start L1 measurement according to the L1 measurement result and / or L3 measurement result of the serving cell.

[0613] Since the L3 measurement result is obtained after multiple filtering of multiple L1 measurement results, compared with the L1 measurement, the L3 measurement has a larger delay. Therefore, for application scenarios with different delay requirements, the terminal can determine the communication quality of the serving cell and whether it is necessary to initiate L1 measurement of non-serving cells based on the L1 measurement result and / or L3 measurement result obtained by measuring the measurement reference signal of the serving cell. In this way, for scenarios with higher delay requirements, it can be determined more quickly whether it is necessary to initiate L1 measurement of non-serving cells based on the L1 measurement result of the serving cell, thereby reducing delay.

[0614] In some embodiments, the serving cell may include: a PCell and / or a PSCell.

[0615] In some embodiments, the non-serving cell may include at least one of the following:

[0616] One or more candidate cells or candidate cell groups corresponding to the LTM configuration configured in the network device;

[0617] Neighboring cell corresponding to L1 measurement configured by the network device.

[0618] In yet other embodiments, the non-serving cell may include:

[0619] The network device corresponding to the serving cell is a candidate cell configured for the terminal;

[0620] The cell is configured with L1 measurement and / or measurement reporting configuration by the network device corresponding to the non-serving cell.

[0621] In some embodiments, the candidate cell may be at least one candidate cell or a candidate cell group configured by the network device for the terminal to perform LTM.

[0622] In some embodiments, the candidate cells may include at least one of the following:

[0623] Cells in the candidate MCG for performing LTM;

[0624] Candidate PCells for performing LTM;

[0625] cells in the candidate SCG for performing LTM;

[0626] Candidate PSCells for performing LTM.

[0627] In some embodiments, the candidate cell group may include at least one of the following:

[0628] Candidate MCGs for performing LTM;

[0629] Candidate SCGs for performing LTM.

[0630] In some embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the serving cell, including at least one of the following:

[0631] Determine whether to start L1 measurement of the terminal's candidate MCG and / or candidate PCell based on the cell measurement result of the serving primary cell PCell;

[0632] Determine whether to start L1 measurement of non-serving cells based on the cell measurement result of the serving primary cell (PCell), where the L1 measurement of the non-serving cells is associated with the configuration of the serving MCG and / or serving PCell;

[0633] Determine whether to start L1 measurement of the terminal's candidate SCG and / or candidate PSCell based on the cell measurement results of the primary and secondary cells (PSCells);

[0634] According to the cell measurement result of the serving primary and secondary cell PSCell, it is determined whether to start L1 measurement of non-serving cells, where the L1 measurement of the non-serving cells is associated with the configuration of the serving SCG and / or serving PSCell.

[0635] It should be noted that the L1 measurement of the non-service cell is associated with the configuration of the service MCG and / or service PCell. It can be understood that the L1 measurement configuration of the L1 measurement of the non-service cell can refer to the L1 measurement configuration of the service MCG and / or service PCell.

[0636] The L1 measurement of the non-serving cell is associated with the configuration of the serving SCG and / or serving PSCell. It can be understood that the L1 measurement configuration of the L1 measurement of the non-serving cell can refer to the L1 measurement configuration of the serving SCG and / or serving PSCell.

[0637] In some embodiments, the cell measurement result of the serving cell includes at least one of the following:

[0638] L3 measurement results of the measurement reference signal on the serving cell;

[0639] L3 measurement results of one or more beams of the serving cell;

[0640] The average of the L3 measurement results of multiple beams of the serving cell;

[0641] L1 measurement results of the measurement reference signal on the serving cell;

[0642] L1 measurement results of one or more beams of the serving cell;

[0643] The average of the L1 measurement results of multiple beams of the serving cell.

[0644] In some embodiments, the serving cell may include multiple different beams, and the measurement reference signals may be transmitted using the multiple different beams.

[0645] The terminal can receive measurement reference signals transmitted using multiple different beams, and determine the communication quality of the serving cell and the beam performance of multiple beams of the serving cell based on the L3 measurement results of the measurement reference signals transmitted using multiple different beams.

[0646] The L1 measurement results and / or L3 measurement results of one or more beams of the serving cell can be understood as, when the terminal performs L1 measurement and / or L3 measurement of the serving cell, it can monitor one or more specific beams of the serving cell to obtain the L1 measurement results and / or L3 measurement results of one or more specific beams, thereby eliminating the need to monitor all beams of the serving cell and reducing the power consumption of the terminal.

[0647] In some embodiments, the one or more beams include at least one of the following:

[0648] One or more beams determined based on a network device configuration;

[0649] One or more beams agreed upon by the protocol.

[0650] It can be understood that one or more beams may be beams specified by the network device, or beams determined by the terminal according to criteria agreed upon in the protocol.

[0651] For example, the beam may be one or more beams with the best current performance, or one or more beams whose measurement results are greater than a specific value.

[0652] It is worth noting that when the terminal performs L1 measurement and / or L3 measurement of the service cell, it can directly monitor the target beam pre-configured by the network device and / or the beam agreed upon by the protocol to obtain the L1 measurement results and / or L3 measurement results of one or more specific beams of the service cell; thereby eliminating the need to monitor all beams of the service cell and reducing the power consumption of the terminal.

[0653] In some embodiments, the terminal may determine the target beam based on the first information sent by the network device.

[0654] In some embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the serving cell, including at least one of the following:

[0655] If the cell measurement result of the serving cell is less than or equal to the measurement threshold, the terminal determines to start L1 measurement;

[0656] The cell measurement result of the serving cell is greater than the measurement threshold, and the terminal determines not to start L1 measurement.

[0657] It should be noted that the measurement threshold value may be the minimum threshold value of the cell signal that meets the communication requirements of the terminal.

[0658] It can be understood that if the cell measurement result of the service cell is less than or equal to the measurement threshold value, it means that the communication quality of the service cell is poor and the terminal has a cell switching requirement; based on this, the terminal can start L1 measurement to report the L1 measurement result to the network device, assisting the network device to determine whether the terminal executes LTM and determine the target cell to be switched.

[0659] If the cell measurement result of the serving cell is greater than the measurement threshold, it indicates that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal may not start L1 measurement to reduce unnecessary L1 measurements and lower the power consumption and signaling overhead of the terminal.

[0660] In some other embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the serving cell, including at least one of the following:

[0661] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines to start L1 measurement;

[0662] The cell measurement result of the serving cell is greater than or equal to the measurement threshold, and the terminal determines not to start L1 measurement.

[0663] In some other embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the serving cell, including at least one of the following:

[0664] If the cell measurement result of the serving cell is greater than or equal to the measurement threshold, the terminal determines to start L1 measurement;

[0665] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines not to start L1 measurement.

[0666] It should be noted that the measurement threshold value may be the highest threshold value of the cell signal that meets the communication requirements of the terminal.

[0667] It can be understood that if the cell measurement result of the service cell is greater than or equal to the measurement threshold value, it means that the communication quality of the service cell is poor and the terminal has a cell switching requirement; based on this, the terminal can start L1 measurement to report the L1 measurement result to the network device, assisting the network device to determine whether the terminal executes LTM and determine the target cell to be switched.

[0668] The cell measurement result of the serving cell is less than the measurement threshold, indicating that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal may not start L1 measurement to reduce the measurement power consumption of the terminal.

[0669] In some other embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the serving cell, including at least one of the following:

[0670] If the cell measurement result of the serving cell is greater than the measurement threshold, the terminal determines to start L1 measurement;

[0671] The cell measurement result of the serving cell is less than or equal to the measurement threshold, and the terminal determines not to start L1 measurement.

[0672] In some embodiments, determining whether to stop L1 measurement according to the cell measurement result includes at least one of the following:

[0673] If the cell measurement result of the serving cell is less than or equal to the measurement threshold, the terminal determines not to stop L1 measurement;

[0674] The cell measurement result of the serving cell is greater than the measurement threshold, and the terminal determines to stop L1 measurement.

[0675] It should be noted that the measurement threshold value may be the minimum threshold value of the cell signal that meets the communication requirements.

[0676] It is understandable that if the cell measurement result of the serving cell is less than or equal to the measurement threshold, it means that the communication quality of the serving cell is poor and the terminal needs to switch cells. Based on this, the terminal needs to continue to maintain (periodic) L1 measurement in order to report the L1 measurement result to the network device.

[0677] The cell measurement result of the serving cell is greater than the measurement threshold, indicating that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal can stop L1 measurement to reduce the measurement power consumption of the terminal.

[0678] In some other embodiments, determining whether to stop L1 measurement according to the cell measurement result includes at least one of the following:

[0679] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines not to stop L1 measurement;

[0680] If the cell measurement result of the serving cell is greater than or equal to the measurement threshold, the terminal determines to stop L1 measurement.

[0681] In some other embodiments, determining whether to stop L1 measurement according to the cell measurement result includes at least one of the following:

[0682] If the cell measurement result of the serving cell is greater than or equal to the measurement threshold, the terminal determines not to stop L1 measurement;

[0683] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines to stop L1 measurement.

[0684] It should be noted that the measurement threshold value may be the highest threshold value of the cell signal that meets the communication requirements.

[0685] It is understandable that if the cell measurement result of the serving cell is greater than or equal to the measurement threshold, it means that the communication quality of the serving cell is poor and the terminal needs to switch cells. Based on this, the terminal needs to continue to maintain (periodic) L1 measurement in order to report the L1 measurement result to the network device.

[0686] The cell measurement result of the serving cell is less than the measurement threshold, indicating that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal can stop L1 measurement to reduce the measurement power consumption of the terminal.

[0687] In some other embodiments, determining whether to stop L1 measurement according to the cell measurement result includes at least one of the following:

[0688] The cell measurement result of the serving cell is greater than the measurement threshold, and the terminal determines not to stop L1 measurement;

[0689] If the cell measurement result of the serving cell is less than or equal to the measurement threshold, the terminal determines to stop L1 measurement.

[0690] In some embodiments, determining to activate or deactivate L1 measurement reporting based on the cell measurement result includes at least one of the following:

[0691] If the cell measurement result of the serving cell is less than or equal to the measurement threshold, the terminal determines to activate L1 measurement reporting;

[0692] The cell measurement result of the serving cell is greater than the measurement threshold, and the terminal determines to deactivate L1 measurement reporting.

[0693] It should be noted that the measurement threshold value may be the minimum threshold value of the cell signal that meets the communication requirements.

[0694] It can be understood that the cell measurement result of the serving cell is less than or equal to the measurement threshold value, indicating that the communication quality of the serving cell is poor and the terminal has a cell switching requirement; based on this, the terminal activates L1 measurement reporting so that the network device determines whether the terminal executes LTM and determines the target cell to be switched based on the L1 measurement result reported by the terminal.

[0695] The cell measurement result of the serving cell is greater than the measurement threshold, indicating that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal can deactivate L1 measurement reporting to reduce the occupation of transmission resources.

[0696] In some other embodiments, determining to activate or deactivate L1 measurement reporting according to the cell measurement result includes at least one of the following:

[0697] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines to activate L1 measurement reporting;

[0698] If the cell measurement result of the serving cell is greater than or equal to the measurement threshold, the terminal determines to deactivate L1 measurement reporting.

[0699] In some other embodiments, determining to activate or deactivate L1 measurement reporting according to the cell measurement result includes at least one of the following:

[0700] If the cell measurement result of the serving cell is greater than or equal to the measurement threshold, the terminal determines to activate L1 measurement reporting;

[0701] The cell measurement result of the serving cell is less than the measurement threshold, and the terminal determines to deactivate L1 measurement reporting.

[0702] It should be noted that the measurement threshold value may be the highest threshold value of the cell signal that meets the communication requirements.

[0703] It can be understood that if the cell measurement result of the service cell is greater than or equal to the measurement threshold value, it means that the communication quality of the service cell is poor and the terminal has a cell switching requirement; based on this, the terminal activates L1 measurement reporting so that the network device determines whether the terminal executes LTM and determines the target cell to be switched based on the L1 measurement result reported by the terminal.

[0704] The cell measurement result of the serving cell is less than the measurement threshold, indicating that the communication quality of the serving cell is good and the terminal does not need to switch cells. Based on this, the terminal can deactivate L1 measurement reporting to reduce the occupation of transmission resources.

[0705] In some other embodiments, determining to activate or deactivate L1 measurement reporting according to the cell measurement result includes at least one of the following:

[0706] The cell measurement result of the serving cell is greater than the measurement threshold, and the terminal determines to activate L1 measurement reporting;

[0707] The cell measurement result of the serving cell is less than or equal to the measurement threshold, and the terminal determines to deactivate L1 measurement reporting.

[0708] In some embodiments, the measurement threshold value includes at least one of the following:

[0709] Measurement thresholds based on network device configuration;

[0710] The measurement threshold value agreed upon in the protocol;

[0711] The measurement threshold is determined based on the measurement capability of the terminal.

[0712] It is understandable that the measurement threshold value may be configured by the network device, or may be a default value agreed upon by the protocol.

[0713] In some embodiments, the measurement capabilities of the terminal may include at least one of the following:

[0714] The maximum number of measurement frequencies supported by the terminal;

[0715] The number of frequencies that the terminal can currently measure.

[0716] It is understandable that the terminal can determine the measurement threshold value on its own according to its own measurement capability, thereby performing L1 measurement within the scope of its own measurement capability.

[0717] In some embodiments, after determining to start the L1 measurement, the L1 measurement is performed according to measurement-related parameters of the L1 measurement.

[0718] In some embodiments, the measurement-related parameters of the L1 measurement are determined by the measurement-related parameters corresponding to the cell measurement result;

[0719] or,

[0720] The measurement-related parameters of L1 measurement are determined by the L1 measurement configuration configured by the network device for the terminal;

[0721] or,

[0722] The measurement-related parameters of L1 measurement are agreed upon by the protocol.

[0723] It should be noted that the measurement-related parameters for the L1 measurement are determined by the measurement-related parameters corresponding to the cell measurement result. It can be understood that the measurement-related parameters for the L1 measurement of the non-serving cell initiated by the terminal are the same as the measurement-related parameters for the L1 measurement and / or L3 measurement performed by the terminal on the serving cell. For example, the terminal may perform L3 measurement on the SSB for the serving cell and determine whether to initiate L1 measurement of the non-serving cell based on the L3-RSRP of the SSB. If it is determined to initiate L1 measurement of the candidate cell, L1 measurement may be performed on the SSB of the non-serving cell to obtain the L1-RSRP of the non-serving cell.

[0724] In some embodiments, measurement-related parameters of L1 measurement of a non-serving cell initiated by the terminal may be different from measurement-related parameters of L1 measurement and / or L3 measurement performed by the terminal on a serving cell.

[0725] For example, the terminal may perform L3 measurement on the SSB for the serving cell, and determine whether to start L1 measurement of the non-serving cell based on the L3-RSRP of the SSB; if it is determined to start L1 measurement of the non-serving cell, L1 measurement may be performed on the CSI-RS of the non-serving cell to obtain the L1-SINR of the serving cell and / or the non-serving cell.

[0726] The information processing method involved in the embodiment of the present disclosure may include at least one of steps S2201 to S2203. For example, step S2201 may be implemented as an independent embodiment, and step S2201 combined with step S2203 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0727] In some embodiments, steps S2202 and S2203 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that the terminal may perform L1 measurement on all candidate cells preconfigured by the network device for performing LTM, and the terminal does not need to determine whether to initiate L1 measurement based on the cell measurement results.

[0728] In some embodiments, step S2202 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that the initiation or change of L1 measurement may be controlled by the network device, that is, the network device triggers the terminal to initiate L1 measurement by sending trigger signaling, without the terminal performing cell measurement, and determines whether to initiate L1 measurement based on the cell measurement results.

[0729] FIG2c is an interactive diagram illustrating an information processing method according to an exemplary embodiment. As shown in FIG2c, the embodiment of the present disclosure relates to an information processing method for use in a communication system 100, the method comprising:

[0730] Step S2301: The network device sends first information to the terminal.

[0731] In some embodiments, the terminal receives first information sent by the network device.

[0732] In some embodiments, the terminal may be a terminal supporting dual connectivity, multiple connectivity or carrier aggregation.

[0733] In some embodiments, the terminal may be a terminal supporting L1 measurement.

[0734] In some embodiments, the terminal may be an LTM-capable terminal.

[0735] Exemplarily, supporting LTM may include supporting LTM for PCell or MCG, supporting LTM for PSCell or SCG, or supporting both.

[0736] In some embodiments, the network device may be an access network device corresponding to a serving cell or a source cell to which the terminal is currently accessing.

[0737] In some embodiments, the network device may be an access network device corresponding to a primary cell or a primary cell group of the terminal.

[0738] In some embodiments, the network device may be an access network device corresponding to a primary or secondary cell or a secondary cell group of the terminal.

[0739] In some embodiments, the first information may include: LTM configurations corresponding to one or more candidate cells.

[0740] In some embodiments, the LTM configuration may be an LTM configuration corresponding to a layer 1 (Layer 1, L1) or layer 2 (Layer 2, L2) triggered mobility LTM configured by the network device for the terminal.

[0741] In some embodiments, the L1 / L1-triggered mobility LTM may include at least one of the following:

[0742] L1 / L2 triggered mobility of primary cell group or primary cell;

[0743] L1 / L2 triggered mobility of the secondary cell group or primary and secondary cells.

[0744] In some embodiments, the mobility of the primary cell group or primary cell triggered by L1 / L2 is used to control the terminal to change its serving primary cell group or primary cell among multiple candidate primary cell groups or candidate primary cells corresponding to the terminal's serving primary cell group or primary cell.

[0745] In some embodiments, the mobility of the secondary cell group or primary and secondary cell triggered by L1 / L2 is used for the terminal to change its serving secondary cell group or primary and secondary cell among multiple candidate secondary cell groups or candidate primary and secondary cells corresponding to the terminal's serving secondary cell group or primary and secondary cell.

[0746] In some embodiments, the first information may include at least one of the following:

[0747] One or more configuration information identifiers;

[0748] One or more non-serving cells or non-serving cell group identifiers to be measured;

[0749] One or more candidate cells or candidate cell group identifiers to be measured;

[0750] measurement configuration of one or more non-serving cells or groups of non-serving cells;

[0751] measurement configuration of one or more candidate cells or candidate cell groups;

[0752] mobility configuration of one or more candidate cells;

[0753] One or more measurement thresholds.

[0754] In some embodiments, measuring the threshold value may include:

[0755] Threshold corresponding to the L3 measurement result.

[0756] It should be noted that whether to start L1 measurement is determined based on the comparison result between the L3 measurement result of the non-serving cell and the threshold value. The L1 measurement includes but is not limited to: L1 measurement of the non-serving cell.

[0757] In some embodiments, the measurement threshold value includes at least one of the following:

[0758] Measurement thresholds based on network device configuration;

[0759] The measurement threshold value agreed upon in the protocol;

[0760] The threshold value is determined by the UE based on implementation.

[0761] It is understandable that the measurement threshold value may be configured by the network device, or the measurement threshold value may be a default value agreed upon by the protocol, or a threshold value determined by the UE based on implementation.

[0762] In some embodiments, the measurement threshold may be configured to initiate L1 measurement for non-serving cells.

[0763] In some embodiments, the measurement threshold value may be independently configured for different non-serving cells, or a universal measurement threshold value may be configured.

[0764] In some embodiments, the thresholds for initiating L1 measurements of different non-serving cells may be the same or different.

[0765] In some embodiments, the measurement quantities corresponding to the thresholds for initiating L1 measurements of different non-serving cells may be the same or different, wherein the measurement quantity may be at least one of RSRQ, RSRP, and SINR.

[0766] Exemplarily, for the independently configured threshold value, the network side configures threshold value #1 for non-serving cell 1, and the UE determines whether to start L1 measurement of non-serving cell 1 based on the comparison between the L3 measurement result of non-serving cell 1 and threshold value #1.

[0767] Exemplarily, for the commonly configured threshold value, the network side configures a common threshold value #0 for all non-service cells configured with L1 measurement configuration. The UE determines whether to start L1 measurement of one or more non-service cells configured with L1 configuration by the network based on the comparison of the L3 measurement results of the non-service cells with the threshold value #0.

[0768] In some embodiments, the first information may be sent via signaling.

[0769] In some embodiments, the first information may be sent via L1 signaling.

[0770] In some embodiments, L1 signaling includes at least downlink control information (DCI).

[0771] In some embodiments, the first information may be sent via L2 signaling.

[0772] In some embodiments, L2 signaling includes at least: a Media Access Control (MAC) control element (CE), etc.

[0773] In some embodiments, the first information may be sent via L3 signaling.

[0774] In some embodiments, L3 signaling may include: Radio Resource Control (RRC) signaling.

[0775] Step S2302: The terminal performs mobility measurement on a non-serving cell.

[0776] In some embodiments, the terminal performs L3 measurements on non-serving cells.

[0777] It is worth noting that the terminal can perform L3 measurements on non-serving cells to determine whether the communication quality of the non-serving cell is better than that of the serving cell based on the measurement results of the L3 measurements of the non-serving cell. It is understandable that if the communication quality of the non-serving cell is worse than that of the serving cell, the terminal does not need to perform cell handover, and on this basis, there is no need to perform L1 measurements for LTM.

[0778] In some embodiments, the non-serving cell may include at least one of the following:

[0779] One or more candidate cells or candidate cell groups corresponding to the LTM configuration configured in the network device;

[0780] Neighboring cell corresponding to L1 measurement configured by the network device.

[0781] In yet other embodiments, the non-serving cell may include:

[0782] The network device corresponding to the serving cell is a candidate cell configured for the terminal;

[0783] The cell is configured with L1 measurement and / or measurement reporting configuration by the network device corresponding to the non-serving cell.

[0784] In some embodiments, the candidate cell may be at least one candidate cell or a candidate cell group configured by the network device for the terminal to perform LTM.

[0785] In some embodiments, the candidate cells may include at least one of the following:

[0786] Cells in the candidate MCG for performing LTM;

[0787] Candidate PCells for performing LTM;

[0788] cells in the candidate SCG for performing LTM;

[0789] Candidate PSCells for performing LTM.

[0790] In some embodiments, the candidate cell group may include at least one of the following:

[0791] Candidate MCGs for performing LTM;

[0792] Candidate SCGs for performing LTM.

[0793] In some embodiments, the terminal performs L3 measurement on a non-serving cell, which may include:

[0794] The terminal performs L3 measurement on the candidate cell.

[0795] In some embodiments, the terminal performs L3 measurement on the candidate cell, which may include at least one of the following:

[0796] The terminal performs L3 measurement on the candidate cells in the candidate MCG;

[0797] The terminal performs L3 measurement on the candidate cells in the candidate SCG;

[0798] The terminal performs L3 measurement on the candidate PCell;

[0799] The terminal performs L3 measurement on the candidate PSCell.

[0800] In some embodiments, the terminal performs L3 measurement on a non-serving cell, which may include:

[0801] The terminal performs L3 measurement on the non-serving cell measurement object corresponding to the non-serving cell.

[0802] The non-serving cell may be one or more of a non-serving PCell, a non-serving PSCell, and a non-serving SCell.

[0803] It can be understood that the terminal in the embodiment of the present disclosure may be a terminal that supports dual connectivity, multi-connectivity or carrier aggregation, and the terminal can access two cells or two cell groups at the same time to improve the transmission rate. Therefore, the terminal performs L3 measurement on the candidate cell, which may be to perform L3 measurement on the candidate MCG or candidate PCell configured by the terminal to determine the communication quality of the candidate MCG or candidate PCell; or to perform L3 measurement on the candidate SCG or candidate PSCell configured by the terminal to determine the communication quality of the candidate SCG or candidate PSCell. According to the communication quality of the candidate MCG or candidate PCell, determine whether it is necessary to switch the MCG or PCell; according to the communication quality of the candidate SCG or candidate PSCell, determine whether it is necessary to switch the SCG or PSCell.

[0804] In some embodiments, L3 measurements may include Radio Resource Management (RRM) measurements.

[0805] In some embodiments, L3 measurements are used for mobility management of terminals.

[0806] It should be noted that mobility management refers to the process of managing terminal service continuity. It optimizes the connection between terminals and network devices, ensuring the availability of various network services and maintaining optimal network coverage or connectivity.

[0807] In some embodiments, the terminal may perform L3 measurement on the candidate cell based on the L3 measurement configuration corresponding to the candidate cell of the LTM pre-configured by the network device.

[0808] In some embodiments, the L3 measurement configuration may include: measurement-related parameters of the L3 measurement.

[0809] In some embodiments, the measurement-related parameters of the L3 measurement may include at least one of the following:

[0810] Measuring reference signals;

[0811] measurement quantity;

[0812] Configuration information for measuring reference signals.

[0813] It should be noted that the measurement reference signal may be a reference signal periodically broadcast by a cell. A terminal may receive the measurement reference signal and determine the communication quality of the cell based on the signal strength of the measurement reference signal.

[0814] The measurement quantity may be a measurement value of a measurement reference signal determined by measurement; in some embodiments, the measurement quantity may be a parameter used to describe a performance indicator of the measurement reference signal. For example, the measurement quantity may be a channel quality indicator (CQI).

[0815] The configuration information of the measurement reference signal is used by the terminal to determine the signal resource of the measurement reference signal.

[0816] It can be understood that the terminal may receive the measurement reference signal according to the configuration information of the measurement reference signal, and perform measurement based on the received measurement reference signal to obtain a measurement value corresponding to the measurement reference signal.

[0817] In some embodiments, the configuration information for measuring reference signals may include at least one of the following:

[0818] identification of the measurement reference signal;

[0819] Resource configuration for measuring reference signals;

[0820] Period configuration of the measurement reference signal.

[0821] In some embodiments, the resource configuration of the sounding reference signal may be used to indicate the time-frequency resource location of the sounding reference signal.

[0822] It should be noted that the configuration information of the measurement reference signal is used by the terminal to monitor the measurement reference signal according to the configuration information of the measurement reference signal.

[0823] In some embodiments, measuring the reference signal may include at least one of the following:

[0824] Synchronization and system information block SSB;

[0825] Channel State Information-Reference Signal CSI-RS.

[0826] L3 measurement may be performed based on the SSB and / or CSI-RS of the candidate cell to determine an L3 measurement result of the candidate cell.

[0827] In some embodiments, the measurement quantity of the L3 measurement may include at least one of the following:

[0828] Reference Signal Receiving Power (RSRP);

[0829] Reference Signal Receiving Quality (RSRQ);

[0830] Reference signal to interference-plus-noise ratio (SINR).

[0831] It can be understood that the L3 measurement result of the candidate cell may include: one or more of L3-RSRP, L3-RSRQ, and L3-SINR.

[0832] Step S2303: The terminal determines whether to perform L1 measurement related operations.

[0833] In some embodiments, the terminal determines whether to perform L1 measurement-related operations based on cell measurement results of non-serving cells.

[0834] In some embodiments, the terminal determines whether to perform L1 measurement-related operations based on the cell measurement results of the candidate cells.

[0835] In some embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the candidate cell, which may include at least one of the following:

[0836] Determine whether to start L1 measurement based on the cell measurement results of the candidate cell;

[0837] Determine whether to stop L1 measurement based on the cell measurement results of the candidate cell;

[0838] Activate or deactivate L1 measurement reporting based on the cell measurement results of the candidate cells.

[0839] Because L1 measurement results are used by the network device to determine whether a terminal should perform LTM, if the candidate cell's measurement results indicate that the candidate cell's communication quality is inferior to that of the serving cell, the network device will not control the terminal to perform LTM, even if the terminal performs and reports L1 measurements. This allows the network device to determine whether to initiate L1 measurements based on the serving cell's measurement results, even if the terminal's own measurement capabilities are insufficient. This reduces unnecessary measurements and lowers the terminal's measurement power consumption.

[0840] Alternatively, when the terminal is configured to periodically start L1 measurement, the terminal may determine whether to stop L1 measurement according to the cell measurement result, so as to reduce the measurement power consumption of the terminal.

[0841] Alternatively, when transmission resources are limited, the terminal can determine whether to activate or deactivate L1 measurement reporting based on the cell measurement results, thereby effectively saving transmission resources. It should be noted that after completing the L1 measurement, the terminal can determine whether to report the L1 measurement results to the network device based on the cell measurement results. This can reduce unnecessary L1 measurement reporting when transmission resources are limited and the signal quality of the terminal's serving cell is good.

[0842] It is worth noting that the start and stop of L1 measurement and / or the activation and deactivation of L1 measurement reporting can be determined by the terminal without being triggered by the network device, thereby reducing the additional signaling overhead introduced by network device control and reducing latency.

[0843] In some embodiments, the L1 measurement may be a beam measurement.

[0844] It should be noted that in New Radio (NR), especially when the communication frequency band is in Frequency Range (FR) 2, due to the rapid attenuation of high-frequency channels, in order to ensure the coverage of the signal, terminals and network devices can send and receive information based on beams.

[0845] In some embodiments, a cell may include multiple beams.

[0846] In some embodiments, the measurement results of the L1 measurement may be used to determine the beam performance of one or more beams of the cell.

[0847] In some embodiments, the measurement result of the L1 measurement can be used to determine the serving beam for communication between the terminal and the network device from multiple beams in the cell.

[0848] In some embodiments, the measurement result of the L1 measurement is used to determine whether to perform a mobility operation LTM triggered by the layer L1 or the layer L2.

[0849] In some embodiments, the measurement result of L1 measurement is used to assist the network device in performing cell handover decision.

[0850] It should be noted that the terminal performs L1 measurement and reports the measurement results of the L1 measurement to the network device, so that the network device can determine the beam performance and / or cell performance of the cell based on the measurement results of the L1 measurement reported by the terminal, and then determine whether the terminal needs to perform cell switching; when it is determined that the terminal needs to perform cell switching, the service cell is changed through L1 or L2 signaling, and the corresponding service beam is selected to achieve rapid switching of the cell and achieve the purpose of low latency and low overhead.

[0851] In some embodiments, the L1 measurement includes at least one of the following:

[0852] L1 measurements based on one or more measurement configurations corresponding to the LTM configuration configured on the network device;

[0853] Based on measurements reported for triggering LTM;

[0854] Beam measurements based on one or more beams configured by the network device for performing LTM.

[0855] It is understandable that the network device may pre-configure the LTM configuration for the terminal; it should be noted that the LTM configuration is used by the terminal to perform mobility operations related to the LTM configuration.

[0856] In some embodiments, the LTM configuration may include at least one of the following:

[0857] One or more candidate cells configured by the network device for the terminal;

[0858] L1 measurement configuration, where the L1 measurement configuration may be a measurement configuration corresponding to one or more candidate cells.

[0859] In some embodiments, the L1 measurement configuration may not be included in the LTM configuration, and may be sent to the UE by the network side through other information, for example, it may be sent to the UE together with the L3 measurement configuration, or it may be sent to the UE separately.

[0860] Exemplarily, the terminal may initiate L1 measurement based on one or more pre-configured measurement configurations for performing LTM, and report the measurement result of the L1 measurement, so as to assist the network device in performing LTM decision by using the L1 measurement result.

[0861] Exemplarily, the terminal may initiate L1 measurement based on one or more pre-configured measurement configurations for performing LTM, and trigger LTM-based cell change based on the L1 measurement result.

[0862] Alternatively, the terminal may perform other measurements that can trigger LTM measurement reporting, so as to use the measurement results to assist the network device in performing LTM decision.

[0863] Alternatively, the network device may be pre-configured with one or more dedicated beams, and the beam performance of the beam is used to assist the network device in determining whether the terminal needs to perform LTM.

[0864] The terminal can perform beam measurement based on one or more pre-configured dedicated beams, so as to use the beam measurement results to assist the network device in performing LTM decision.

[0865] Alternatively, this dedicated beam is determined by the UE based on implementation or protocol provisions, such as the best one or more beams in a cell, or one or more beams in a cell that are greater than a threshold configured by the network or a threshold agreed upon by the protocol.

[0866] It is worth noting that the terminal can determine whether to start any of the above measurements based on the cell measurement results, so as to assist the network device in performing LTM decision by reporting the measurement results to the network device, thereby improving the flexibility of the started L1 measurement.

[0867] In some embodiments, the terminal determines whether to start L1 measurement based on the L3 measurement result of the candidate cell.

[0868] The terminal can determine the communication quality of the candidate cell based on the L3 measurement result obtained by measuring the measurement reference signal of the candidate cell, thereby determining whether to start L1 measurement, reducing unnecessary L1 measurement and lowering the power consumption of the terminal.

[0869] In some embodiments, the terminal determines whether to start L1 measurement according to the L3 measurement result of the non-serving cell, including: determining whether to start L1 measurement associated with the non-serving cell according to the L3 measurement result of the candidate cell.

[0870] In some embodiments, determining whether to start L1 measurement of the non-service cell is based on the L3 measurement result of the non-service cell. This can be understood as determining whether to start beam measurement of multiple beams of the non-service cell based on the L3 measurement result of a specific beam of the non-service cell.

[0871] In some embodiments, the measurement period of the L1 measurement of the non-serving cell is smaller than the measurement period of the L3 measurement of the non-serving cell.

[0872] It is worth noting that the measurement power consumption corresponding to the L3 measurement of the non-serving cell is less than the measurement power consumption corresponding to the L1 measurement of the non-serving cell. In this way, the terminal can determine whether to initiate the L1 measurement of the non-serving cell with greater measurement power consumption based on the L3 measurement result of the non-serving cell with lower measurement power consumption.

[0873] In some embodiments, the L1 measurement configuration of the non-serving cell includes at least one of the following:

[0874] Dedicated L1 measurement configuration configured by the network device for non-serving cells;

[0875] L1 measurement configuration generated by the source MCG;

[0876] L1 measurement configuration generated by the source SCG.

[0877] It is understandable that the network device pre-configures a dedicated L1 measurement configuration for the non-serving cell. When the terminal determines to start L1 measurement of the non-serving cell, it can perform L1 measurement on the corresponding non-serving cell based on the L1 measurement configuration of the non-serving cell configured by the network device.

[0878] In some embodiments, the terminal may directly refer to the L1 measurement configuration generated by the source MCG or the source SCG to perform L1 measurement on the non-serving cell, thereby eliminating the need for the network device to separately configure a dedicated L1 measurement configuration for the non-serving cell.

[0879] In some embodiments, the cell measurement result of the non-serving cell includes at least one of the following:

[0880] L3 measurement results of measurement reference signals on non-serving cells;

[0881] L3 measurement results of one or more beams of the non-serving cell;

[0882] The average of the L3 measurement results of multiple beams of the non-serving cell.

[0883] In some embodiments, the non-serving cell may include multiple different beams, and the measurement reference signal may be transmitted using the multiple different beams.

[0884] The terminal can receive measurement reference signals transmitted using multiple different beams, and determine the communication quality of the non-service cell and the beam performance of multiple beams of the non-service cell based on the L3 measurement results of the measurement reference signals transmitted using multiple different beams.

[0885] The L3 measurement results of one or more beams of the non-service cell can be understood as that when the terminal performs L3 measurement of the non-service cell, it can monitor one or more specific beams of the non-service cell to obtain the L3 measurement results of one or more specific beams, thereby eliminating the need to monitor all beams of the non-service cell and reducing the power consumption of the terminal.

[0886] In some embodiments, the one or more beams include at least one of the following:

[0887] One or more beams determined based on a network device configuration;

[0888] One or more beams agreed upon by the protocol.

[0889] It can be understood that one or more beams may be beams specified by the network device, or beams determined by the terminal according to criteria agreed upon in the protocol.

[0890] For example, the beam may be one or more beams with the best current performance, or one or more beams whose measurement results are greater than a specific value.

[0891] It is worth noting that when the terminal performs L3 measurement of non-service cells, it can directly monitor the beams pre-configured by the network equipment and / or the beams agreed upon by the protocol to obtain the L3 measurement results of one or more specific beams of the service cell; thereby eliminating the need to monitor all beams of non-service cells and reducing the power consumption of the terminal.

[0892] In some embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the non-serving cell, including at least one of the following:

[0893] If the cell measurement result of the non-serving cell is less than or equal to the measurement threshold, the terminal determines not to initiate L1 measurement;

[0894] The cell measurement result of the non-serving cell is greater than the measurement threshold, and the terminal determines to start L1 measurement.

[0895] It should be noted that the measurement threshold value may be the minimum threshold value of the cell signal that meets the communication requirements of the terminal.

[0896] It can be understood that the cell measurement result of the non-service cell is less than or equal to the measurement threshold value, indicating that the communication quality of the non-service cell is poor and the terminal does not need to switch cells; based on this, the terminal may not start L1 measurement to reduce unnecessary L1 measurements and reduce the terminal's power consumption and signaling overhead.

[0897] If the cell measurement result of the non-serving cell is greater than the measurement threshold, it means that the communication quality of the non-serving cell is good and the terminal may have a cell handover requirement. Based on this, the terminal can start L1 measurement to report the L1 measurement result to the network device to assist the network device in determining whether the terminal performs LTM and determine the target cell to be handed over.

[0898] In some other embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the non-serving cell, including at least one of the following:

[0913] It should be noted that the measurement threshold value may be the minimum threshold value of the cell signal that meets the communication requirements of the terminal.

[0914] It is understandable that if the cell measurement result of the non-serving cell is less than or equal to the measurement threshold, it means that the communication quality of the non-serving cell is poor and the terminal does not need to switch cells. Based on this, the terminal can stop L1 measurement to reduce the measurement power consumption of the terminal.

[0946] In some embodiments, the measurement threshold value includes at least one of the following:

[0947] Measurement thresholds based on network device configuration;

[0948] The measurement threshold value agreed upon in the protocol;

[0949] The measurement threshold is determined based on the measurement capability of the terminal.

[0950] It is understandable that the measurement threshold value may be configured by the network device, or may be a default value agreed upon by the protocol.

[0951] In some embodiments, the measurement capabilities of the terminal may include at least one of the following:

[0952] The maximum number of measurement frequencies supported by the terminal;

[0953] The number of frequencies that the terminal can currently measure.

[0954] It is understandable that the terminal can determine the measurement threshold value on its own according to its own measurement capability, thereby performing L1 measurement within the scope of its own measurement capability.

[0955] In some embodiments, after determining to start the L1 measurement, the L1 measurement is performed according to measurement-related parameters of the L1 measurement.

[0956] In some embodiments, the measurement-related parameters of the L1 measurement may include at least one of the following:

[0957] Measuring reference signals;

[0958] measurement quantity;

[0959] Configuration information for measuring reference signals.

[0965] It should be noted that the configuration information of the measurement reference signal is used by the terminal to monitor the measurement reference signal according to the configuration information of the measurement reference signal.

[0966] In some embodiments, measuring the reference signal may include at least one of the following:

[0967] Synchronization and system information block SSB;

[0968] Channel State Information-Reference Signal CSI-RS.

[0969] In some embodiments, the measurement quantity of L1 measurement may include at least one of the following:

[0970] Reference Signal Receiving Power (RSRP);

[0971] Reference Signal Receiving Quality (RSRQ);

[0972] Reference signal to interference-plus-noise ratio (SINR).

[0973] In some embodiments, the measurement-related parameters of the L1 measurement are determined by the measurement-related parameters corresponding to the cell measurement result;

[0974] or,

[0975] The measurement-related parameters of L1 measurement are determined by the L1 measurement configuration configured by the network device for the terminal;

[0976] or,

[0977] The measurement-related parameters of L1 measurement are agreed upon by the protocol.

[0978] It should be noted that the measurement-related parameters for the L1 measurement are determined by the measurement-related parameters corresponding to the cell measurement result. It can be understood that the measurement-related parameters for the L1 measurement initiated by the terminal are the same as the measurement-related parameters for the L3 measurement performed by the terminal on the non-serving cell. For example, the terminal may perform L3 measurement on the SSB for the non-serving cell and determine whether to initiate L1 measurement of the non-serving cell based on the L3-RSRP of the SSB. If the L1 measurement is determined to be initiated, the L1 measurement may be performed on the SSB of the non-serving cell to obtain the L1-RSRP of the non-serving cell.

[0979] In some embodiments, the measurement-related parameters of the L1 measurement initiated by the terminal may be different from the measurement-related parameters of the L3 measurement performed by the terminal on the non-serving cell.

[0980] For example, the terminal can perform L3 measurement on the SSB for the non-serving cell, and determine whether to start L1 measurement of the non-serving cell based on the L3-RSRP of the SSB; if it is determined to start L1 measurement, L1 measurement can be performed on the CSI-RS of the non-serving cell to obtain the L1-SINR of the non-serving cell.

[0981] The information processing method involved in the embodiments of the present disclosure may include at least one of steps S2301 to S2303. For example, step S2301 may be implemented as an independent embodiment, and step S2301 combined with step S2303 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0982] In some embodiments, steps S2302 and S2303 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that the terminal may perform L1 measurement on all candidate cells preconfigured by the network device for performing LTM, and the terminal does not need to determine whether to initiate L1 measurement based on the cell measurement results.

[0983] In some embodiments, step S2302 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that the initiation or change of L1 measurement may be controlled by the network device, that is, the network device triggers the terminal to initiate L1 measurement by sending trigger signaling, without the terminal performing cell measurement, and determines whether to initiate L1 measurement based on the cell measurement results.

[0995] In some embodiments, the LTM configuration may be an LTM configuration corresponding to a layer 1 (Layer 1, L1) or layer 2 (Layer 2, L2) triggered mobility LTM configured by the network device for the terminal.

[0996] In some embodiments, the L1 / L1-triggered mobility LTM may include at least one of the following:

[0997] L1 / L2 triggered mobility of primary cell group or primary cell;

[0998] L1 / L2 triggered mobility of the secondary cell group or primary and secondary cells.

[0999] In some embodiments, the mobility of the primary cell group or primary cell triggered by L1 / L2 is used to control the terminal to change its serving primary cell group or primary cell among multiple candidate primary cell groups or candidate primary cells corresponding to the terminal's serving primary cell group or primary cell.

[1000] In some embodiments, the mobility of the secondary cell group or primary and secondary cell triggered by L1 / L2 is used for the terminal to change its serving secondary cell group or primary and secondary cell among multiple candidate secondary cell groups or candidate primary and secondary cells corresponding to the terminal's serving secondary cell group or primary and secondary cell.

[1001] In some embodiments, the first information may include at least one of the following:

[1007] measurement configuration of one or more candidate cells or candidate cell groups;

[1008] mobility configuration of one or more candidate cells;

[1009] One or more measurement thresholds.

[1010] In some embodiments, measuring the threshold value may include:

[1011] Threshold corresponding to the L3 measurement result.

[1012] It should be noted that whether to start L1 measurement is determined based on the comparison between the L3 measurement results of the non-serving cell at one or more reference frequencies and the threshold value. The L1 measurement includes but is not limited to: L1 measurement of the non-serving cell.

[1013] In some embodiments, the measurement threshold value includes at least one of the following:

[1014] Measurement thresholds based on network device configuration;

[1015] The measurement threshold value agreed upon in the protocol;

[1016] The threshold value is determined by the UE based on implementation.

[1017] It is understandable that the measurement threshold value may be configured by the network device, or the measurement threshold value may be a default value agreed upon by the protocol, or a threshold value determined by the UE based on implementation.

[1018] In some embodiments, the measurement threshold may be configured to initiate L1 measurement for non-serving cells.

[1019] In some embodiments, the measurement threshold value may be independently configured for different non-serving cells, or a universal measurement threshold value may be configured.

[1020] In some embodiments, the measurement threshold may be independently configured for non-serving cells at different reference frequencies.

[1021] In some embodiments, the thresholds for initiating L1 measurements of different non-serving cells may be different or may be different.

[1022] In some embodiments, the measurement quantities corresponding to the thresholds for initiating L1 measurements of different non-serving cells may be the same or different, wherein the measurement quantity may be at least one of RSRQ, RSRP, and SINR.

[1023] Exemplarily, for threshold values ​​independently configured for different non-serving cells, the network side configures threshold value #1 for non-serving cell 1. The UE determines whether to start L1 measurement based on the comparison between the L3 measurement result of non-serving cell 1 and threshold value #1.

[1024] Exemplarily, for the threshold values ​​independently configured for non-service cells with different reference frequencies, the network side configures threshold value #2 for one or more non-service cells under reference frequency 1, and the UE determines whether to start L1 measurement based on the comparison of the L3 measurement results of one or more non-service cells under reference frequency 1 with threshold value #2.

[1025] Exemplarily, for the commonly configured threshold value, the network side configures a common threshold value #0 for non-service cells at one or more reference frequencies, and the UE determines whether to start L1 measurement based on a comparison of the L3 measurement results of the non-service cells at one or more reference frequencies with the threshold value #0.

[1026] In some embodiments, the first information may be sent via signaling.

[1027] In some embodiments, the first information may be sent via L1 signaling.

[1028] In some embodiments, L1 signaling includes at least downlink control information (DCI).

[1029] In some embodiments, the first information may be sent via L2 signaling.

[1030] In some embodiments, L2 signaling includes at least: a Media Access Control (MAC) control element (CE), etc.

[1031] In some embodiments, the first information may be sent via L3 signaling.

[1032] In some embodiments, L3 signaling may include: Radio Resource Control (RRC) signaling.

[1033] Step S2402: The terminal performs mobility measurement on a non-serving cell.

[1034] In some embodiments, the terminal performs L3 measurement on non-serving cells corresponding to one or more reference frequencies.

[1035] It should be noted that in order to reduce interference between cells, frequencies can be allocated to different cells. Multiple cells corresponding to the same frequency can be called intra-frequency cells; multiple cells corresponding to different frequencies can be called inter-frequency cells.

[1036] In some embodiments, non-serving cells may include:

[1037] One or more candidate cells or candidate cell groups corresponding to the LTM configuration configured in the network device;

[1038] Neighboring cell corresponding to L1 measurement configured by the network device.

[1039] In yet other embodiments, the non-serving cell may include:

[1040] The network device corresponding to the serving cell is a candidate cell configured for the terminal;

[1041] The cell is configured with L1 measurement and / or measurement reporting configuration by the network device corresponding to the non-serving cell.

[1042] In some embodiments, the candidate cell may be at least one candidate cell or a candidate cell group configured by the network device for the terminal to perform LTM.

[1043] In some embodiments, the candidate cells may include at least one of the following:

[1044] Cells in the candidate MCG for performing LTM;

[1045] Candidate PCells for performing LTM;

[1046] cells in the candidate SCG for performing LTM;

[1047] Candidate PSCells for performing LTM.

[1048] In some embodiments, the candidate cell group may include at least one of the following:

[1049] Candidate MCGs for performing LTM;

[1050] Candidate SCGs for performing LTM.

[1051] In some embodiments, the terminal may perform L3 measurements on non-serving cells corresponding to one or more reference frequencies, which may include:

[1052] The terminal performs L3 measurement on candidate cells corresponding to one or more reference frequencies.

[1053] It can be understood that the network device can pre-configure multiple candidate cells for the terminal to perform LTM. In order to reduce measurement power consumption, the terminal can determine one or more candidate cells corresponding to the reference frequency from the multiple candidate cells pre-configured by the network device, and only perform L3 measurement on the candidate cell, which can effectively reduce the number of candidate cells that need to be measured.

[1054] It is worth noting that the terminal can perform L3 measurements on candidate cells corresponding to one or more reference frequencies to determine whether the communication quality of the candidate cells is better than the communication quality of the serving cell based on the measurement results of the L3 measurements of the candidate cells. It is understood that if the communication quality of the candidate cell is worse than the communication quality of the serving cell, the terminal does not need to perform cell handover, and on this basis, there is no need to perform L1 measurements for LTM.

[1055] In some embodiments, the terminal performs L3 measurement on candidate cells corresponding to one or more reference frequencies, which may include at least one of the following:

[1056] The terminal performs L3 measurement on the candidate cells in the candidate MCG corresponding to the reference frequency;

[1057] The terminal performs L3 measurement on the candidate cells in the candidate SCG corresponding to the reference frequency;

[1058] The terminal performs L3 measurement on the candidate PCell corresponding to the reference frequency;

[1059] The terminal performs L3 measurement on the candidate PSCell corresponding to the reference frequency;

[1060] In some embodiments, the terminal performs L3 measurement on a non-serving cell, which may include:

[1061] The terminal performs L3 measurement on the non-serving cell measurement object corresponding to the non-serving cell.

[1062] The non-serving cell may be one or more of a non-serving PCell, a non-serving PSCell, and a non-serving SCell.

[1063] It is understood that in the embodiments of the present disclosure, the terminal may be a terminal that supports dual connectivity, multi-connectivity, or carrier aggregation, and the terminal may access two cells or two cell groups simultaneously to improve the transmission rate. Therefore, the terminal performs L3 measurement on the candidate cell, which may be to perform L3 measurement on the candidate MCG and / or candidate PCell corresponding to the reference frequency among the multiple candidate MCGs or candidate PCells configured for the terminal to determine the communication quality of the candidate MCG and / or candidate PCell corresponding to the reference frequency; determine whether to switch the MCG or PCell based on the communication quality of the candidate MCG or candidate PCell corresponding to the reference frequency;

[1064] It is also possible to perform L3 measurement on the candidate SCG or candidate PSCell corresponding to the reference frequency among the multiple candidate SCGs or candidate PSCells configured by the terminal to determine the communication quality of the candidate SCG or candidate PSCell corresponding to the reference frequency; and determine whether it is necessary to switch the SCG or PSCell based on the communication quality of the candidate SCG or candidate PSCell corresponding to the reference frequency.

[1065] In some embodiments, L3 measurements may include Radio Resource Management (RRM) measurements.

[1066] In some embodiments, L3 measurements are used for mobility management of terminals.

[1067] It should be noted that mobility management refers to the process of managing terminal service continuity. It optimizes the connection between terminals and network devices, ensuring the availability of various network services and maintaining optimal network coverage or connectivity.

[1068] In some embodiments, the terminal may perform L3 measurement on the candidate cells corresponding to the reference frequency based on the L3 measurement configuration corresponding to one or more candidate cells corresponding to the reference frequency among the candidate cells of the LTM pre-configured by the network device.

[1069] In some embodiments, the L3 measurement configuration may include: measurement-related parameters of the L3 measurement.

[1070] In some embodiments, the measurement-related parameters of the L3 measurement may include at least one of the following:

[1071] Measuring reference signals;

[1072] measurement quantity;

[1073] Configuration information for measuring reference signals.

[1074] It should be noted that the measurement reference signal may be a reference signal periodically broadcast by a cell. A terminal may receive the measurement reference signal and determine the communication quality of the cell based on the signal strength of the measurement reference signal.

[1075] The measurement quantity may be a measurement value of a measurement reference signal determined by measurement; in some embodiments, the measurement quantity may be a parameter used to describe a performance indicator of the measurement reference signal. For example, the measurement quantity may be a channel quality indicator (CQI).

[1076] The configuration information of the measurement reference signal is used by the terminal to determine the signal resource of the measurement reference signal.

[1077] It can be understood that the terminal may receive the measurement reference signal according to the configuration information of the measurement reference signal, and perform measurement based on the received measurement reference signal to obtain a measurement value corresponding to the measurement reference signal.

[1078] In some embodiments, the configuration information for measuring reference signals may include at least one of the following:

[1079] identification of the measurement reference signal;

[1080] Resource configuration for measuring reference signals;

[1081] Period configuration of the measurement reference signal.

[1082] In some embodiments, the resource configuration of the sounding reference signal may be used to indicate the time-frequency resource location of the sounding reference signal.

[1083] It should be noted that the configuration information of the measurement reference signal is used by the terminal to monitor the measurement reference signal according to the configuration information of the measurement reference signal.

[1084] In some embodiments, measuring the reference signal may include at least one of the following:

[1085] Synchronization and system information block SSB;

[1086] Channel State Information-Reference Signal CSI-RS.

[1087] L3 measurement may be performed based on the SSB and / or CSI-RS of the candidate cell corresponding to one or more reference frequencies to determine the L3 measurement result of the candidate cell.

[1088] In some embodiments, the measurement quantity of the L3 measurement may include at least one of the following:

[1089] Reference Signal Receiving Power (RSRP);

[1090] Reference Signal Receiving Quality (RSRQ);

[1091] Reference signal to interference-plus-noise ratio (SINR).

[1092] It can be understood that the L3 measurement result of the candidate cell may include: one or more of L3-RSRP, L3-RSRQ, and L3-SINR.

[1093] Step S2403: The terminal determines whether to perform L1 measurement related operations.

[1094] In some embodiments, the terminal determines whether to perform L1 measurement-related operations based on cell measurement results of non-serving cells corresponding to one or more reference frequencies.

[1095] In some embodiments, the terminal determines whether to start L1 measurement based on the cell measurement results of the non-serving cell corresponding to one or more reference frequencies, which may include at least one of the following:

[1096] determining whether to initiate L1 measurement based on cell measurement results of non-serving cells corresponding to one or more reference frequencies;

[1097] determining whether to stop L1 measurement based on cell measurement results of non-serving cells corresponding to one or more reference frequencies;

[1098] L1 measurement reporting is activated or deactivated based on the cell measurement results of the non-serving cell corresponding to one or more reference frequencies.

[1099] Because L1 measurement results are used by the network device to determine whether a terminal should perform LTM, if the cell measurement results of a non-serving cell indicate that the communication quality of the non-serving cell is inferior to that of the serving cell, the network device will not control the terminal to perform LTM even if the terminal performs and reports L1 measurements. This allows the network device to determine whether to initiate L1 measurements based on the cell measurement results of the serving cell, even if the terminal's own measurement capabilities are insufficient. This reduces unnecessary measurements and reduces the terminal's measurement power consumption.

[1100] Alternatively, when the terminal is configured to periodically start L1 measurement, the terminal may determine whether to stop L1 measurement according to the cell measurement result, so as to reduce the measurement power consumption of the terminal.

[1101] Alternatively, when transmission resources are limited, the terminal can determine whether to activate or deactivate L1 measurement reporting based on the cell measurement results, thereby effectively saving transmission resources. It should be noted that after completing the L1 measurement, the terminal can determine whether to report the L1 measurement results to the network device based on the cell measurement results. This can reduce unnecessary L1 measurement reporting when transmission resources are limited and the signal quality of the terminal's serving cell is good.

[1102] It is worth noting that the start and stop of L1 measurement and / or the activation and deactivation of L1 measurement reporting can be determined by the terminal without being triggered by the network device, thereby reducing the additional signaling overhead introduced by network device control and reducing latency.

[1103] In some embodiments, the L1 measurement may be a beam measurement.

[1104] It should be noted that in New Radio (NR), especially when the communication frequency band is in Frequency Range (FR) 2, due to the rapid attenuation of high-frequency channels, in order to ensure the coverage of the signal, terminals and network devices can send and receive information based on beams.

[1105] In some embodiments, a cell may include multiple beams.

[1106] In some embodiments, the measurement results of the L1 measurement may be used to determine the beam performance of one or more beams of the cell.

[1107] In some embodiments, the measurement result of the L1 measurement can be used to determine the serving beam for communication between the terminal and the network device from multiple beams in the cell.

[1108] In some embodiments, the measurement result of the L1 measurement is used to determine whether to perform a mobility operation LTM triggered by the layer L1 or the layer L2.

[1109] In some embodiments, the measurement result of L1 measurement is used to assist the network device in performing cell handover decision.

[1110] It should be noted that the terminal performs L1 measurement and reports the measurement results of the L1 measurement to the network device, so that the network device can determine the beam performance and / or cell performance of the cell based on the measurement results of the L1 measurement reported by the terminal, and then determine whether the terminal needs to perform cell switching; when it is determined that the terminal needs to perform cell switching, the service cell is changed through L1 or L2 signaling, and the corresponding service beam is selected to achieve rapid switching of the cell and achieve the purpose of low latency and low overhead.

[1111] In some embodiments, the L1 measurement includes at least one of the following:

[1112] L1 measurements based on one or more measurement configurations corresponding to the LTM configuration configured on the network device;

[1113] Based on measurements reported for triggering LTM;

[1114] Beam measurements based on one or more beams configured by the network device for performing LTM.

[1115] It is understandable that the network device may pre-configure the LTM configuration for the terminal; it should be noted that the LTM configuration is used by the terminal to perform mobility operations related to the LTM configuration.

[1116] In some embodiments, the LTM configuration may include at least one of the following:

[1117] One or more candidate cells configured by the network device for the terminal;

[1118] L1 measurement configuration, where the L1 measurement configuration may be a measurement configuration corresponding to one or more candidate cells.

[1119] In some embodiments, the L1 measurement configuration may not be included in the LTM configuration, and may be sent to the UE by the network side through other information, for example, it may be sent to the UE together with the L3 measurement configuration, or it may be sent to the UE separately.

[1120] Exemplarily, the terminal may initiate L1 measurement based on one or more pre-configured measurement configurations for performing LTM, so as to utilize the measurement result of the L1 measurement, so as to utilize the L1 measurement result to assist the network device in performing LTM decision.

[1121] Exemplarily, the terminal may initiate L1 measurement based on one or more pre-configured measurement configurations for performing LTM, and trigger LTM-based cell change based on the L1 measurement result.

[1122] Alternatively, the terminal may perform other measurements that can trigger LTM measurement reporting, so as to use the measurement results to assist the network device in performing LTM decision.

[1123] Alternatively, the network device may be pre-configured with one or more dedicated beams, and the beam performance of the beam is used to assist the network device in determining whether the terminal needs to perform LTM.

[1124] The terminal can perform beam measurement based on one or more pre-configured dedicated beams, so as to use the beam measurement results to assist the network device in performing LTM decision.

[1125] Alternatively, this dedicated beam is determined by the UE based on implementation or protocol provisions, such as the best one or more beams in a cell, or one or more beams in a cell that are greater than a threshold configured by the network or a threshold agreed upon by the protocol.

[1126] It is worth noting that the terminal can determine whether to start any of the above measurements based on the cell measurement results, so as to assist the network device in performing LTM decision by reporting the measurement results to the network device, thereby improving the flexibility of the started L1 measurement.

[1127] In some embodiments, the terminal determines whether to start L1 measurement based on cell measurement results of non-serving cells corresponding to one or more reference frequencies, which may include:

[1128] The terminal determines whether to start L1 measurement according to the L3 measurement results of the candidate cells corresponding to one or more reference frequencies.

[1129] The terminal can determine the communication quality of the candidate cell based on the L3 measurement results obtained by measuring the measurement reference signals of the candidate cell corresponding to one or more reference frequencies, thereby determining whether it is necessary to start L1 measurement. On the one hand, the terminal does not need to send the measurement results to the network device, and the network device does not need to trigger the start of L1 measurement based on the measurement results, thereby reducing signaling overhead and latency. On the other hand, during the L3 measurement process, L3 measurement is only performed on the candidate cells corresponding to one or more reference frequencies, thereby reducing the number of candidate cells to be measured and reducing the power consumption of the terminal.

[1130] In some embodiments, the terminal may determine whether to start L1 measurement of candidate cells corresponding to all frequency bands supported by the terminal based on L3 measurement results of candidate cells corresponding to one or more reference frequencies.

[1131] In some embodiments, the terminal determines whether to start L1 measurement corresponding to the reference frequency based on L3 measurement results of candidate cells corresponding to one or more reference frequencies.

[1132] In some embodiments, the terminal determines whether to start L1 measurement corresponding to the reference frequency based on the L3 measurement results of the candidate cells corresponding to one or more reference frequencies. It can be understood that based on the L3 measurement results of specific beams of the candidate cells corresponding to one or more reference frequencies, it is determined whether to start beam measurement of multiple beams of the candidate cells corresponding to the reference frequency.

[1133] In some embodiments, a measurement period of L1 measurement of candidate cells corresponding to one or more reference frequencies is smaller than a measurement period of L3 measurement of candidate cells corresponding to the reference frequencies.

[1134] It is worth noting that the measured power consumption of the L3 measurement of the candidate cell corresponding to the reference frequency is less than the measured power consumption of the L1 measurement of the candidate cell corresponding to the reference frequency. In this way, the terminal can determine whether to initiate L1 measurement of the candidate cell with greater measurement power consumption based on the L3 measurement result of the candidate cell with lower measurement power consumption.

[1135] In some embodiments, the L1 measurement configuration of the non-serving cell includes at least one of the following:

[1136] Dedicated L1 measurement configuration configured by the network device for non-serving cells;

[1137] L1 measurement configuration generated by the source MCG;

[1138] L1 measurement configuration generated by the source SCG.

[1139] It is understandable that the network device pre-configures a dedicated L1 measurement configuration for the non-serving cell. When the terminal determines to start L1 measurement of the non-serving cell, it can perform L1 measurement on the corresponding non-serving cell based on the L1 measurement configuration of the non-serving cell configured by the network device.

[1140] In some embodiments, the terminal may directly refer to the L1 measurement configuration generated by the source MCG or the source SCG to perform L1 measurement on the non-serving cell, thereby eliminating the need for the network device to separately configure a dedicated L1 measurement configuration for the non-serving cell.

[1141] In some embodiments, the cell measurement result of the serving cell includes at least one of the following:

[1142] L3 measurement results of measurement reference signals on non-serving cells;

[1143] L3 measurement results of one or more beams of the non-serving cell;

[1144] The average of the L3 measurement results of multiple beams of the non-serving cell.

[1145] In some embodiments, the non-serving cell may include multiple different beams, and the measurement reference signal may be transmitted using the multiple different beams.

[1146] The terminal can receive measurement reference signals transmitted using multiple different beams, and determine the communication quality of the non-service cell and the beam performance of multiple beams of the non-service cell based on the L3 measurement results of the measurement reference signals transmitted using multiple different beams.

[1147] The L3 measurement results of one or more beams of the non-service cell can be understood as that when the terminal performs L3 measurement of the non-service cell, it can monitor one or more specific beams of the non-service cell to obtain the L3 measurement results of one or more specific beams, thereby eliminating the need to monitor all beams of the non-service cell and reducing the power consumption of the terminal.

[1148] In some embodiments, the one or more beams include at least one of the following:

[1149] One or more beams determined based on a network device configuration;

[1150] One or more beams agreed upon by the protocol.

[1151] It can be understood that one or more beams may be beams specified by the network device, or beams determined by the terminal according to criteria agreed upon in the protocol.

[1152] For example, the beam may be one or more beams with the best current performance, or one or more beams whose measurement results are greater than a specific value.

[1153] It is worth noting that when the terminal performs L3 measurement of non-service cells, it can directly monitor the beams pre-configured by the network equipment and / or the beams agreed upon by the protocol to obtain the L3 measurement results of one or more specific beams of the service cell; thereby eliminating the need to monitor all beams of non-service cells and reducing the power consumption of the terminal.

[1154] In some embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the non-serving cell, including at least one of the following:

[1155] If the maximum value of the L3 measurement results of the non-serving cell corresponding to one or more reference frequencies is less than or equal to the measurement threshold, the terminal determines not to initiate L1 measurement;

[1156] The maximum value of the L3 measurement results of the non-serving cell corresponding to one or more reference frequencies is greater than the measurement threshold, and the terminal determines to start the L1 measurement.

[1157] It should be noted that the measurement threshold value may be the minimum threshold value of the cell signal that meets the communication requirements of the terminal.

[1158] It can be understood that the maximum value of the L3 measurement results of the candidate cells corresponding to one or more reference frequencies is less than or equal to the measurement threshold value, indicating that the communication quality of the candidate cells corresponding to the reference frequencies is poor and the terminal does not have a cell switching requirement; based on this, the terminal may not start L1 measurement to reduce unnecessary L1 measurements and reduce the terminal's power consumption and signaling overhead.

[1159] If the L3 measurement results of the non-service cells corresponding to one or more reference frequencies are greater than the measurement threshold value, it means that the communication quality of the non-service cells corresponding to the reference frequencies is good, and the terminal may have a cell switching requirement. Based on this, the terminal can start L1 measurement to report the L1 measurement results to the network device, assisting the network device in determining whether the terminal executes LTM and determining the target cell to be switched.

[1160] In some other embodiments, the terminal determines whether to start L1 measurement based on the cell measurement result of the non-serving cell, including at least one of the following:

[1165] The maximum value of the L3 measurement results of the non-serving cell corresponding to one or more reference frequencies is less than the measurement threshold, and the terminal determines to start the L1 measurement.

[1166] It should be noted that the measurement threshold value may be the highest threshold value of the cell signal that meets the communication requirements of the terminal.

[1167] It can be understood that the maximum value of the L3 measurement results of the candidate cells corresponding to one or more reference frequencies is greater than or equal to the measurement threshold value, indicating that the communication quality of the candidate cells corresponding to the reference frequencies is poor and the terminal does not have a cell switching requirement; based on this, the terminal may not start L1 measurement to reduce unnecessary L1 measurements and reduce the terminal's power consumption and signaling overhead.

[1168] If the L3 measurement results of the non-service cells corresponding to one or more reference frequencies are less than the measurement threshold value, it means that the communication quality of the non-service cells corresponding to the reference frequencies is good, and the terminal may have a cell switching requirement. Based on this, the terminal can start L1 measurement to report the L1 measurement results to the network device, assisting the network device in determining whether the terminal executes LTM and determining the target cell to be switched.

[1171] If the maximum value of the L3 measurement results of the non-serving cell corresponding to one or more reference frequencies is less than or equal to the measurement threshold, the terminal determines to start the L1 measurement.

[1172] In some embodiments, determining whether to stop L1 measurement according to the cell measurement result includes at least one of the following:

[1173] If the maximum value of the L3 measurement results of the non-serving cell corresponding to one or more reference frequencies is less than or equal to the measurement threshold, the terminal determines to stop the L1 measurement;

[1174] The maximum value of the L3 measurement results of the non-serving cell corresponding to one or more reference frequencies is greater than the measurement threshold, and the terminal determines not to stop the L1 measurement.

[1175] It should be noted that the measurement threshold value may be the minimum threshold value of the cell signal that meets the communication requirements of the terminal.

[1176] It can be understood that the maximum value of the L3 measurement results of the candidate cells corresponding to one or more reference frequencies is less than or equal to the measurement threshold value, indicating that the communication quality of the candidate cells corresponding to the reference frequencies is poor and the terminal does not have a cell switching requirement; based on this, the terminal can stop L1 measurement to reduce the measurement power consumption of the terminal.

[1177] The L3 measurement results of the non-service cells corresponding to one or more reference frequencies are greater than the measurement threshold value, indicating that the communication quality of the non-service cells corresponding to the reference frequencies is good, and the terminal may have a cell switching requirement. Based on this, the terminal needs to continue to maintain (periodic) L1 measurement in order to report the L1 measurement results to the network device.

[1178] In some other embodiments, determining whether to stop L1 measurement according to the cell measurement result includes at least one of the following:

[1179] The maximum value of the L3 measurement results of the non-serving cell corresponding to one or more reference frequencies is less than the measurement threshold, and the terminal determines to stop the L1 measurement;

[1180] If the maximum value of the L3 measurement results of the non-serving cell corresponding to one or more reference frequencies is greater than or equal to the measurement threshold, the terminal determines not to stop the L1 measurement.

[1185] It can be understood that the maximum value of the L3 measurement results of the candidate cells corresponding to one or more reference frequencies is greater than or equal to the measurement threshold value, indicating that the communication quality of the candidate cells corresponding to the reference frequencies is poor and the terminal does not have a cell switching requirement; based on this, the terminal can stop L1 measurement to reduce the measurement power consumption of the terminal.

[1186] The L3 measurement results of the non-service cells corresponding to one or more reference frequencies are less than the measurement threshold value, indicating that the communication quality of the non-service cells corresponding to the reference frequencies is good, and the terminal may have a cell switching requirement.

[1187] In some other embodiments, determining whether to stop L1 measurement according to the cell measurement result includes at least one of the following:

[1188] The maximum value of the L3 measurement results of the non-serving cell corresponding to one or more reference frequencies is greater than the measurement threshold, and the terminal determines to stop the L1 measurement;

[1193] It should be noted that the measurement threshold value may be the minimum threshold value of the cell signal that meets the communication requirements of the terminal.

[1194] It can be understood that the maximum value of the L3 measurement results of the candidate cells corresponding to one or more reference frequencies is less than or equal to the measurement threshold value, indicating that the communication quality of the candidate cells corresponding to the reference frequencies is poor and the terminal does not have a cell switching requirement; based on this, the terminal can deactivate L1 measurement reporting to reduce the occupancy of transmission resources.

[1195] If the L3 measurement results of the non-service cells corresponding to one or more reference frequencies are greater than the measurement threshold value, it means that the communication quality of the non-service cells corresponding to the reference frequencies is good, and the terminal may have a cell switching requirement. Based on this, the terminal activates L1 measurement reporting so that the network device determines whether the terminal performs LTM and determines the target cell to be switched based on the L1 measurement results reported by the terminal.

[1196] In some other embodiments, determining to activate or deactivate L1 measurement reporting according to the cell measurement result includes at least one of the following:

[1204] If the L3 measurement results of the non-service cells corresponding to one or more reference frequencies are less than the measurement threshold value, it means that the communication quality of the non-service cells corresponding to the reference frequencies is good, and the terminal may have a cell switching requirement. Based on this, the terminal activates L1 measurement reporting so that the network device determines whether the terminal performs LTM and determines the target cell to be switched based on the L1 measurement results reported by the terminal.

[1205] In some embodiments, determining to activate or deactivate L1 measurement reporting based on the cell measurement result includes at least one of the following:

[1207] If the maximum value of the L3 measurement results of the non-serving cell corresponding to one or more reference frequencies is less than or equal to the measurement threshold, the terminal determines to activate L1 measurement reporting.

[1208] In some embodiments, the measurement threshold value includes at least one of the following:

[1209] Measurement thresholds based on network device configuration;

[1210] The measurement threshold value agreed upon in the protocol;

[1211] The measurement threshold is determined based on the measurement capability of the terminal.

[1212] It is understandable that the measurement threshold value may be configured by the network device, or may be a default value agreed upon by the protocol.

[1213] In some embodiments, the measurement capabilities of the terminal may include at least one of the following:

[1214] The maximum number of measurement frequencies supported by the terminal;

[1215] The number of frequencies that the terminal can currently measure.

[1216] It is understandable that the terminal can determine the measurement threshold value on its own according to its own measurement capability, thereby performing L1 measurement within the scope of its own measurement capability.

[1217] In some embodiments, after determining to start the L1 measurement, the L1 measurement is performed according to measurement-related parameters of the L1 measurement.

[1218] In some embodiments, the measurement-related parameters of the L1 measurement may include at least one of the following:

[1219] Measuring reference signals;

[1220] measurement quantity;

[1221] Configuration information for measuring reference signals.

[1222] In some embodiments, the configuration information for measuring reference signals may include at least one of the following:

[1223] identification of the measurement reference signal;

[1224] Resource configuration for measuring reference signals;

[1225] Period configuration of the measurement reference signal.

[1226] In some embodiments, the resource configuration of the sounding reference signal may be used to indicate the time-frequency resource location of the sounding reference signal.

[1227] It should be noted that the configuration information of the measurement reference signal is used by the terminal to monitor the measurement reference signal according to the configuration information of the measurement reference signal.

[1228] In some embodiments, measuring the reference signal may include at least one of the following:

[1229] Synchronization and system information block SSB;

[1230] Channel State Information-Reference Signal CSI-RS.

[1231] In some embodiments, the measurement quantity of L1 measurement may include at least one of the following:

[1238] or,

[1239] The measurement-related parameters of L1 measurement are agreed upon by the protocol.

[1240] It should be noted that the measurement-related parameters for the L1 measurement are determined by the measurement-related parameters corresponding to the cell measurement result. It can be understood that the measurement-related parameters for the L1 measurement initiated by the terminal are the same as the measurement-related parameters for the L3 measurement performed by the terminal on the non-serving cell. For example, the terminal may perform L3 measurement on the SSB of the non-serving cell and determine whether to initiate L1 measurement based on the L3-RSRP of the SSB. If the decision to initiate L1 measurement is made, L1 measurement may be performed on the SSB of the non-serving cell to obtain the L1-RSRP of the non-serving cell.

[1241] In some embodiments, the measurement-related parameters of the L1 measurement initiated by the terminal may be different from the measurement-related parameters of the L3 measurement performed by the terminal on the non-serving cell.

[1242] For example, the terminal can perform L3 measurement on the SSB for the non-serving cell, and determine whether to start L1 measurement based on the L3-RSRP of the SSB; if it is determined to start L1 measurement, L1 measurement can be performed on the CSI-RS of the non-serving cell to obtain the L1-SINR of the non-serving cell.

[1355] In some embodiments, the terminal receives first information sent by the network device.

[1359] In some embodiments, the optional implementation of step S4101 can refer to the optional implementation of step S2401 in Figure 2d and other related parts of the embodiment involved in Figure 2d, which will not be repeated here.

[1360] In some embodiments, the method further comprises:

[1361] The network device receives the measurement result of the L1 measurement sent by the terminal;

[1362] Based on the measurement result of the L1 measurement, it is determined whether the terminal performs LTM.

[1363] It can be understood that the terminal determines to start L1 measurement based on the cell measurement result and sends the L1 measurement result to the network device, so that the network device can determine the communication quality of the terminal's current service cell based on the L1 measurement result, thereby determining whether the terminal performs LTM.

[1364] In some embodiments, determining whether the terminal performs LTM based on the measurement result of the L1 measurement may include at least one of the following:

[1365] Determine whether the terminal performs LTM based on the measurement result of the L1 measurement of the serving cell;

[1366] The terminal determines whether to perform LTM based on the measurement result of the L1 measurement of the non-serving cell.

[1367] In some embodiments, when a UE receives a configuration that includes L1 measurements, it performs the L1 measurements and reports the corresponding measurements. Because the network preconfigures multiple LTM candidate cell configurations and does not delete these LTM candidate configurations after LTM execution, the UE needs to measure all LTMs configured by the network. Due to the limited measurement capabilities of the UE, measuring all L1 measurements configured by the network results in a large number of unnecessary measurements and reports, increasing the burden on the UE.

[1368] In Release 18, the idea of ​​controlling or changing L1 measurements through L1 / L2 signaling was proposed. Since L1 measurement configuration is based on L3 signaling, the network can control and change L1 measurements and reporting based on L3 signaling. With this network-controlled solution, the network needs to evaluate whether to initiate or change L1 measurements based on information reported by the UE (e.g., L1 or L3 measurement results). This solution introduces latency and incurs additional L1 / 2 / 3 signaling overhead.

[1369] In some embodiments, due to the aforementioned issues, network-side control solutions cannot quickly and effectively adapt to rapidly changing network environments. Therefore, the present invention proposes a method for UE-initiated L1 measurements. In this solution, the UE autonomously determines whether to initiate L1 measurements based on the measurement results and thresholds of the serving cell or LTM candidate cell.

[1370] The UE determines whether to start corresponding L1 measurements based on the measurement results:

[1371] Solution 1: Determine whether to start L1 measurement based on the measurement result (L3) of the serving cell. When the L3 measurement result of the serving cell is less than the threshold, the UE starts L1 measurement; when the L3 measurement result of the serving cell is greater than the threshold, the UE stops L1 measurement.

[1372] Solution 2: Determine whether to start L1 measurement of LTM candidate cells based on the measurement results (L1 / L3) of the serving cell. When the L1 / L3 measurement results of the serving cell are less than the threshold value, the UE starts L1 measurement of the LTM candidate cell; when the measurement results L1 / L3 of the serving cell are greater than the threshold value, the UE stops L1 measurement of the LTM candidate cell.

[1373] Solution 3: Determine whether to start L1 measurement of the corresponding LTM candidate cell based on the L3 measurement result of the LTM candidate cell. When the L3 measurement result of the LTM candidate cell is less than the threshold value, the UE does not start L1 measurement of the corresponding LTM candidate cell; when the L3 measurement result of the LTM candidate cell is greater than the threshold value, the UE starts L1 measurement of the corresponding LTM candidate cell.

[1374] Solution 4: Determine whether to start L1 measurement of a specific RS frequency based on the L3 measurement result of this RS frequency. If the maximum value of the L3 measurement result of the LTM candidate cell of this specific frequency is less than the threshold value, the UE does not start L1 measurement of the corresponding frequency; when the maximum value of the L3 measurement result of the LTM candidate cell of this specific frequency is greater than the threshold value, the UE starts L1 measurement of the corresponding frequency.

[1375] Exemplarily, starting may also be referred to as continuing; stopping may also be referred to as not starting.

[1376] Solution 1: Determine whether to start L1 measurement based on the measurement result of the serving cell.

[1377] 1. Determine whether to initiate an L1 measurement process based on the measurement result of the serving cell, where the process of initiating the L1 measurement may be a process of initiating an L1 measurement process and / or an L1 measurement reporting process, including one or more of the following solutions:

[1378] 1.1 When the L3 measurement result of the serving cell is less than the threshold, the UE starts the L1 measurement process.

[1379] 1.2 When the L3 measurement result of the serving cell is greater than the threshold, the UE stops the L1 measurement process.

[1380] 2. In 1, the UE initiates the L1 measurement process including the L1 measurement process of the serving cell and the L1 measurement process of the non-serving cell (eg, LTM candidate cell).

[1381] 3. In 1, the serving cell can be an SPCell, that is, a PCell or a PSCell.

[1382] 3.1 When the serving cell is PCell, based on the result of L3 measurement of PCell, the UE determines whether to start the L1 measurement procedure of PCell and MCG configuration or the L1 measurement procedure of candidate PCell of LTM.

[1383] 3.2 When the serving cell is a PSCell, based on the L3 measurement results of the PSCell, the UE determines whether to start the L1 measurement procedure of the PCell and SCG configuration or the L1 measurement procedure of the candidate PSCell of the LTM.

[1384] 4. In 1, the threshold value can be at least one of a threshold value configured by the network, a threshold value agreed upon by the protocol, a default threshold value, and a threshold value determined by the UE itself based on implementation (a threshold value determined by the UE itself).

[1385] 5. In 1, L1 measurements include but are not limited to measurements performed based on the measurement configuration included in the LTM configuration, measurements reported using L1 information, and measurements obtained based on the measurement results of the beam configured by the network; L3 measurements in 1 refer to RRM measurement results, which are generally used for mobility management, such as switching, PSCell changes, etc.

[1386] 6. The L3 measurement result of the serving cell in step 1 may be:

[1387] L3 measurement results of the serving cell;

[1388] L3 measurement results of a specific beam of the serving cell;

[1389] The average value of the measurement results of multiple specific beams of the serving cell, where these beams can be determined by the UE according to one or more of network configuration, protocol agreement and specific criteria.

[1390] 7. In 1, the measurement quantity corresponding to the measurement result may be one or more of RSRP, RSRQ, and SINR.

[1391] 8. In 1, the reference signal to be measured can be SSB or CSI-RS.

[1392] 9. Based on 1, 7, or 8, the reference signal corresponding to the condition for initiating measurement and the measurement quantity may correspond to the reference signal and measurement quantity corresponding to the L1 measurement process to be initiated; for example, if the L3-RSRP of the SSB of the serving cell is less than the threshold value, the SSB-based L1-RSRP measurement is initiated.

[1393] The reference signal corresponding to the conditions for initiating measurement may not correspond to the measurement quantity, i.e., it may be determined based on network configuration, protocol provisions, or default values. For example, if the reference signal corresponding to the conditions for initiating measurement is SSB and the measurement quantity is RSRP, then when the RSRP measurement result of the SSB of the serving cell's L3 is less than the threshold, L1 measurement is initiated. The L1 measurement is the L1 measurement configured by the network, and there is no need to distinguish between the measurement quantity and the measurement object.

[1394] Solution 2: Determine whether to start L1 measurement of non-serving cells based on the measurement result of the serving cell.

[1395] 1. Determine whether to initiate L1 measurement of a non-serving cell based on the measurement result of the serving cell, where the process of initiating L1 measurement may be a process of initiating L1 measurement and / or L1 measurement reporting, including one or more of the following solutions:

[1396] 1.1 When the L1 measurement result of the serving cell is less than the threshold, the UE starts the L1 measurement process of the non-serving cell.

[1397] 1.2 When the L3 measurement result of the serving cell is less than the threshold, the UE starts the L1 measurement process of the non-serving cell.

[1398] 1.3 When the L1 measurement result of the serving cell is greater than the threshold, the UE stops the L1 measurement process of the non-serving cell.

[1399] 1.4 When the L3 measurement result of the serving cell is greater than the threshold, the UE stops the L1 measurement process of the non-serving cell.

[1400] 2. In 1, the non-serving cell can be an LTM candidate cell configured by the network, or a cell configured with L1 measurement and reporting configuration by other networks.

[1401] 3. Similar to item 3 of solution 1, based on the type of the serving cell, the UE controls the start and stop of the measurement of the corresponding LTM candidate cells based on the measurement results of the serving cell.

[1402] 4. Similar to 4-9 of Scheme 1.

[1403] Solution 3: Determine whether to start the L1 measurement process of the corresponding non-serving cell based on the L3 measurement result of the non-serving cell.

[1404] 1. Determine whether to initiate an L1 measurement process for the non-serving cell based on the L3 measurement result of the non-serving cell, where the process of initiating the L1 measurement may be a process of initiating an L1 measurement process and / or an L1 measurement reporting process, including one or more of the following solutions:

[1405] 1.1 When the L3 measurement result of a non-serving cell is greater than the threshold, the UE starts the L1 measurement process of this non-serving cell.

[1406] 1.2 When the L3 measurement result of the non-serving cell is less than the threshold, the UE stops the L1 measurement process of this non-serving cell.

[1407] 2. In 1, the non-serving cell can be an LTM candidate cell configured by the network, or a cell configured with L1 measurement and reporting configuration by other networks.

[1408] Exemplarily, the network side configures an LTM candidate cell A for the UE. If the L3 measurement result of A is greater than a threshold value 1, the UE starts the L1 measurement of the candidate cell A.

[1409] 3. In 1, the non-serving cell (or LTM candidate cell) can be one or more of the candidate primary cell PCell of LTM and the candidate primary and secondary cell PSCell of LTM, which can be associated with the L1 measurement configuration generated by the source primary cell group MCG and / or the L1 measurement configuration generated corresponding to the source secondary cell SCG.

[1410] 4. Similar to 4-5, 7-9 of Scheme 1.

[1411] Solution 4: Determine whether to start L1 measurement of a specific RS frequency based on the L3 measurement result of this RS frequency.

[1412] 1. A process for determining whether to initiate L1 measurement of a specific RS frequency based on an L3 measurement result of the RS frequency, wherein the process for initiating L1 measurement may be a process for initiating L1 measurement and / or L1 measurement reporting, including one or more of the following solutions:

[1413] 1.1 If the maximum value of the L3 measurement result of the non-serving cell of this specific frequency is less than the threshold, the UE stops the L1 measurement process of the corresponding frequency;

[1414] 1.2 When the maximum value of the L3 measurement result of the non-serving cell of this specific frequency is greater than the threshold, the UE starts the L1 measurement of the corresponding frequency.

[1415] 2. In 1, the non-serving cell can be a network-configured LTM candidate cell or a cell configured with L1 measurement and reporting configuration on another network. If the L1 measurement configuration configured on the network side is not associated with a specific cell, the non-serving cell in 1 is the non-serving cell that the UE can detect in the time and frequency of the corresponding L1 measurement configuration.
