[0128] In recent years, global interest in services based on unmanned aerial vehicles (UAVs) and other aerial user equipment (UEs) has increased dramatically. These services encompass various aspects such as UAV operation, personal entertainment through flight experiences, and cargo delivery. Furthermore, with the deepening research into 6G technology's seamless, three-dimensional hyper-connectivity and ubiquitous coverage, the use of services based on UAVs and other aerial UEs will become even more widespread in the future. As the foundation of these services, remote control and data transmission capabilities are key aspects ensuring service performance.
[0129] In related technologies, the feasibility of airborne UEs connecting via terrestrial cellular systems has been verified. In implementation, some base stations may deploy dedicated resources (such as upward beams) to provide better coverage for airborne UEs.
[0130] In some embodiments, the spherical conformal phased array, as one of the array forms of conformal arrays, has the ability to scan beams in half-space or even full-space, and can provide upward beams in different directions, which can achieve good coverage of spatial areas, thereby providing better coverage for airborne UEs.
[0131] For example, an array of four spherical layers distributed in [3,6,8,12] can be seen in Figure 2A, which is a schematic diagram of a spherical array according to an embodiment of the present disclosure. Optionally, when the scanning angle of the four spherical layers distributed in [3,6,8,12] is (polar angle th = 0°, azimuth angle ph = 0°), the radiation pattern can be seen in Figure 2B, which is a radiation pattern of a spherical array according to an embodiment of the present disclosure.
[0132] In some embodiments, considering that Layer 1 / L2 Triggered Mobility (LTM) can achieve fast and low-latency handover and can be used to reduce mobility latency, applying LTM to UAV UEs can effectively improve the mobility performance of airborne UEs, reduce handover interruptions, reduce handover latency, reduce handover signaling overhead, and achieve fast and efficient handover.
[0133] In some embodiments, LTM refers to a process in which a primary cell (PCell) or primary secondary cell (PSCell) is switched based on the measurement results of a layer 1 (L1) network through a medium access control (MAC) control element (CE), which may be accompanied by a change in the master cell group (MCG) or secondary cell group (SCG).
[0134] In some embodiments of a 5G system, the network side can provide the terminal with one or more candidate configurations, where a candidate configuration may include one or more cells (or cell groups). The network side can subsequently control the terminal to change between multiple candidate configurations (e.g., changing the working cell (or cell group) from cell (or cell group)-1 to cell (or cell group)-2) via L1 signaling (such as Downlink Control Information (DCI)) or L2 signaling (such as MAC CE). This control signaling can be referred to as cell change control signaling. Furthermore, this process can also be called a network-triggered LTM process.
[0135] In some embodiments, the base station can receive L1 measurement reports from the terminal. Based on these reports, the terminal can change its serving cell via a cell switch command issued by the MAC CE. The cell switch command may indicate an LTM candidate cell configuration pre-provided to the terminal by a base station via Radio Resource Control (RRC) signaling. The terminal can then access the target cell indicated in the received cell switch command.
[0136] For example, the base station pre-sends multiple LTM candidate configurations to the terminal via RRC signaling. When LTM is triggered, the base station indicates the LTM candidate configuration corresponding to the target cell to be accessed by sending a Cell Switch Command MAC CE. The terminal can then apply the corresponding LTM target configuration to complete the serving cell change. The network side's sending of a MAC CE based on L1 measurement results to trigger the Cell Switch enables a rapid response to channel changes and timely handover.
[0137] Among them, the LTM candidate cell configuration can be added, modified, and released by the network side via RRC signaling.
[0138] In some embodiments, L1 measurement reporting may include network (NW) triggered L1 measurement reporting and event triggered L1 measurement reporting.
[0139] In some embodiments, for L1 measurement reporting triggered by NW, the Serving Distributed Unit (S-DU) can generate the LTM Cell Switch Command. In the LTM between CUs (Intra-CU), the Source gNodeB Distributed Unit (Source gNB-DU) can make the Cell switch decision. The S-gNB-DU makes the Cell Switch decision based on the L1 measurement results reported by the terminal to determine the candidate target cell for triggering LTM access. Then, the S-gNB-DU sends the Cell switch command to the terminal.
[0140] In some embodiments, to reduce measurement reporting and improve mobility robustness, event-triggered L1 measurement reporting can be considered. Event-triggered measurement reporting can assist the network side in selecting the target beam and / or cell to trigger advance synchronization, or assist the network side in selecting the target cell and / or the corresponding beam when triggering LTM Cell Switch.
[0141] Event LTM2: The serving cell’s beam performance is worse than the threshold (i.e., the absolute threshold).
[0142] Event LTM3: The candidate cell's beam offset is better than the serving cell's beam;
[0143] Event LTM4: The candidate cell's beam performance is better than the threshold;
[0144] Event LTM5: The serving cell’s beam performance is worse than the first threshold, and the candidate cell’s beam performance is better than the second threshold.
[0145] The serving cell's beam is the current beam, which is the beam indicated by the indicated TCI state. The candidate cell's beam is any one or more beams configured in the candidate reference signal configuration (or measurement resource configuration).
[0146] Among them, event-based L1 measurement reporting is sent to the network via MAC CE messages.
[0147] The configuration of measurement events is in the serving cell configuration, and the configuration of measurement events is associated with the configuration of measurement resources.
[0148] In some embodiments, subsequent LTM can be supported. Subsequent LTM refers to the Subsequent LTM cell handover procedure between candidate cells in the absence of RRC reconfiguration between networks. In other words, after performing mobility operations, the terminal does not delete the LTM configuration information on its own. The LTM configuration information can continue to be used to trigger subsequent LTM even if RRC reconfiguration and updates are not performed.
[0149] It should be noted that when LTM supports Subsequent LTM, the terminal does not need to release the LTM candidate configuration after each LTM Cell Switch. This allows the terminal to continue performing subsequent Cell Switches after mobility is achieved, without RRC reconfiguration or reset. Supporting Subsequent LTM can effectively reduce signaling overhead.
[0150] In some embodiments, LTM can support multiple scenarios. For example, LTM can support intra-gNB-DU and inter-gNB-DU mobility within gNB-DU and gNB-CU. Specifically, LTM supports intra-frequency and inter-frequency mobility, including mobility to inter-frequency cells that are not the current serving cell, and can support the following scenarios:
[0151] PCell variations in non-carrier aggregation (CA) and non-dual connectivity (DC) scenarios;
[0152] PCell changes in CA scenarios;
[0153] In dual-connectivity scenarios, changes to MCG PCell and SCGPSCell occur without the participation of a Mobile Node (MN) (i.e., changes to PSCell within the Serving Node (SN)). LTMs do not support simultaneous PCell and PSCell changes.
[0154] In some embodiments, LTM can be configured using LTM configuration information (LTM-Config). This LTM configuration information may include, but is not limited to, one or more of the following: LTM reference configuration, one or more candidate cell configurations (added, modified, or deleted via ltm-CandidateToReleaseList and ltm-CandidateToAddModList), and LTM Channel State Information (CSI) resource configuration.
[0155] The candidate cell configuration can be configured through LTM candidate cells (LTM-Candidate). The candidate cell configuration may include one or more of the following: configuration identifier, candidate cell identifier, and candidate configuration (represented by RRCReconfiguration), but is not limited to these.
[0156] The LTM candidate configuration is a configuration section in the RRC reconfiguration message, associated with a candidate cell, for example, for LTM or subsequent Cell Paging Channel Activation (CPAC). Optionally, the candidate configuration can be a complete candidate configuration or an incremental configuration relative to a reference configuration.
[0157] In some embodiments, during the LTM process, early uplink and downlink synchronization for candidate cells can be supported, thereby enabling RACH-less LTM Cell Switching during the LTM process. Currently, two schemes are supported for obtaining the TA values of LTM candidate cells in advance: early TA acquisition and UE-based TA measurement, to support RACH-less LTM Cell Switching. Performing early uplink and downlink synchronization for candidate cells to achieve RACH-less LTM Cell Switching can effectively reduce data interruptions during handover.
[0158] In some embodiments, when the network is configured, one or more uplink latency (UL TA) acquisition processes (referred to as early TA) different from those of the current serving cell can be initiated.
[0159] In some embodiments, if the cell has the same Network Timing Advance (NTA) value as the current serving cell or NTA = 0, then an early TA acquisition process is not required.
[0160] In some embodiments, prior to cell handover, the network may require the terminal to perform an early TA acquisition procedure for a candidate cell. The early TA acquisition procedure can be triggered by a Physical Downlink Control Channel (PDCCH) command, or implemented by the terminal performing TA measurements according to its RRC configuration.
[0161] In some embodiments, when the early TA acquisition process is triggered by a PDCCH command, the gNB where the candidate cell is located calculates the TA value and sends it to the gNB where the current serving cell is located. When the serving cell triggers an LTM cell handover, it sends the TA value out via the LTM cell handover command MAC CE.
[0162] In some embodiments, where the early TA acquisition process is implemented by the terminal performing TA measurements according to the RRC configuration, the terminal performs TA measurements on candidate cells according to the RRC configuration, but the specific time at which the terminal performs TA measurements is determined by the terminal implementation. The terminal uses its own measured TA value and performs LTM without a Random Access Channel (RACH) after receiving a cell handover command.
[0163] In some embodiments, the network may also send the TA value in the LTM cell handover command MAC CE without performing early TA acquisition.
[0164] In some embodiments, the RACH process for obtaining early uplink time synchronization (UL TA) for LTM candidate cells uses contention-free random access (CFRA) triggered by PDCCH commands. When the UE sends Message 1 (MSG1), it does not need to monitor the response from the cell. Referring to Figure 3A, which is a schematic diagram of an MSG1 retransmission process according to an embodiment of the present disclosure, as shown in Figure 3A, in order to support the gradual increase of terminal power, the terminal can perform MSG1 retransmission according to the network's instructions.
[0165] In some embodiments, if an arrow in the interaction diagram representing the sending of information, signaling, etc. from one subject to another passes through other subjects, it can be interpreted as the information being forwarded from one subject to another via other subjects, or it can be interpreted as the information being sent from one subject to another without passing through other subjects.
[0166] In some embodiments, for TA calculation based on terminal measurements, the terminal can calculate and obtain the uplink timing of the terminal in cell 2 based on the downlink reception timing deviation between cell 1 and cell 2, and the uplink timing of the terminal in cell 1. Referring to Figure 3B, which is a schematic diagram of TA calculation based on terminal measurements according to an embodiment of this disclosure, as shown in Figure 3B, the TA value can be calculated according to the following calculation method:
[0167] (TA_Cell_2) / 2=(TA_Cell_1) / 2+Rx_Diff
[0168] Where TA_Cell_1 is the TA value of cell 1, TA_Cell_2 is the TA value of cell 2, and Rx_Diff is the downlink reception timing deviation between cell 1 and cell 2.
[0169] In some embodiments, for TA calculation based on terminal measurements, the terminal can calculate and obtain the uplink timing in cell 2 based on the downlink receive timing deviation between cell 1 and cell 2, the uplink timing of the terminal in cell 1, and the downlink transmit time difference between cell 1 and cell 2. Referring to Figure 3C, which is a schematic diagram of another TA calculation based on terminal measurements according to an embodiment of this disclosure, as shown in Figure 3C, the TA value can be calculated according to the following calculation method:
[0170] (TA_Cell_2) / 2=(TA_Cell_1) / 2+Rx_Diff-Tx_Diff
[0171] Where TA_Cell_1 is the TA value of cell 1, TA_Cell_2 is the TA value of cell 2, Rx_Diff is the downlink reception timing deviation between cell 1 and cell 2, and Tx_Diff is the downlink transmission time difference between cell 1 and cell 2.
[0172] In some embodiments, after obtaining the TA value indicated by the network, the terminal may start a time alignment timer (TAT). During the operation of this timer, the terminal considers the TA value to be valid and uses the TA value for uplink transmission.
[0173] In some embodiments, during the LTM process, early downlink synchronization for candidate cells is supported.
[0174] In some embodiments, the terminal can activate the TCI state of one or more cells that are different from the current serving cell based on network configuration or other schemes. For example, the TCI state of these cells can be activated in advance before any LTM candidate cell becomes the serving cell. This allows the UE to perform downlink synchronization with these candidate cells in advance, thereby enabling a faster handover to one of the candidate cells when a Cell Switch is triggered.
[0175] In some embodiments, supporting early uplink synchronization can effectively reduce handover interruption time.
[0176] In 5G, altitude-based mobility management has been studied for airborne UEs, supporting altitude-triggered measurements and measurement reporting. However, for broader coverage, future technologies may support 360-degree spherical antenna arrays to achieve seamless deployment and full coverage in the air. In this deployment scenario, multiple beams cover the same altitude plane, and different locations may correspond to different beam coverage areas. In this case, relying solely on the altitude of the airborne UE to assist in mobility management is not accurate enough.
[0177] Figure 4 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4, the embodiments of the present disclosure relate to a communication method, which includes:
[0178] Step S4101: The network device sends the first information to the terminal.

Alternatively, the first configuration can be used to configure candidate cells, to indicate the candidate cells that the terminal can access in the spatial area. Alternatively, the first configuration can be used to configure beams, to indicate which beam's coverage area the terminal belongs to in the spatial area.
[0189] That is, in some embodiments, the first information can be used to indicate at least one of the following: the association between measurement resource configuration and spatial region, the association between measurement event configuration and spatial region, the association between measurement reporting configuration and spatial region, the association between TCI status and spatial region, the association between candidate cell and spatial region, and the association between beam and spatial region.
[0190] In some embodiments, the first information is used to indicate the association between measurement resource configurations and spatial regions; that is, the first information can be used to indicate measurement resource configurations corresponding to different spatial regions. Optionally, a spatial region can correspond to at least one measurement resource configuration, or multiple spatial regions can correspond to one measurement resource configuration. In other words, the measurement resource configurations corresponding to different spatial regions can be the same or different. For example, different spatial resources can correspond to different synchronization signal blocks (SSBs).
[0191] In some embodiments, the terms "synchronization signal block (SSB)," "synchronization signal (SS)," "reference signal (RS)," "pilot," and "pilot signal" can be used interchangeably.
[0192] In some embodiments, measurement resource configuration may include measurement object configuration, channel state information (CSI) measurement, etc., but is not limited thereto.
[0193] In some embodiments, the first information is used to indicate the association between measurement event configurations and spatial regions; that is, the first information can be used to indicate measurement event configurations corresponding to different spatial regions. Optionally, a spatial region can correspond to at least one measurement event configuration, or multiple spatial regions can correspond to a single measurement event configuration; that is, the measurement event configurations corresponding to different spatial regions can be the same or different.
[0194] In some embodiments, the measurement event configuration may be at least one of measurement events such as L1 measurement, LTM measurement, Layer 2 (L2) measurement, Layer 3 (L3) measurement, Radio Resource Management (RRM) measurement, beam measurement, cell measurement, etc., but is not limited thereto.

[0217] In addition, reporting events related to the airborne UE altitude can be labeled HN, where N equals 1 and 2. Reporting events simultaneously related to the airborne UE altitude and neighboring cell measurements are labeled AMHN, where M equals 3, 4, and 5, and N equals 1 and 2.

[0227] It should be noted that although the threshold values involved in different measurement events are referred to by the same name, the content measured by the threshold values with the same name in different measurement events may be the same or different. Furthermore, the values of the threshold values with the same name in different measurement events may be the same or different.
[0228] In some embodiments, the first information is used to indicate the association between measurement reporting configurations and spatial regions; that is, the first information can be used to indicate measurement reporting configurations corresponding to different spatial regions. Optionally, a spatial region can correspond to at least one measurement reporting configuration, or multiple spatial regions can correspond to a measurement reporting configuration; that is, the measurement reporting configurations corresponding to different spatial regions can be the same or different.
[0229] In some embodiments, the measurement reporting configuration may be a reporting configuration, a CSI reporting configuration, etc., but is not limited to these.
[0230] In some embodiments, the first information is used to indicate the association between TCI states and spatial regions; that is, the first information can be used to indicate the TCI states corresponding to different spatial regions. Optionally, a spatial region can correspond to at least one TCI state, or multiple spatial regions can correspond to one TCI state; that is, the TCI states corresponding to different spatial regions can be the same or different.
[0231] In some embodiments, the first information is used to indicate the association between candidate cells and spatial regions; that is, the first information can be used to indicate candidate cells corresponding to different spatial regions. Optionally, a spatial region can correspond to at least one candidate cell (i.e., a spatial region may include at least one candidate cell), or multiple spatial regions can correspond to one candidate cell (i.e., a candidate cell may span multiple spatial regions); that is, candidate cells corresponding to different spatial regions can be the same or different.
[0232] In some embodiments, the first information is used to indicate the association between a beam and a spatial region; that is, the first information can be used to indicate beams corresponding to different spatial regions. Optionally, a spatial region may correspond to at least one beam (i.e., a spatial region may include the coverage area corresponding to at least one beam), or multiple spatial regions may correspond to one beam (i.e., the coverage area of one beam may span multiple spatial regions). In other words, the beams corresponding to different spatial regions may be the same or different.
[0233] In some embodiments, for any of the measurement resource configuration, measurement event configuration, and measurement reporting configuration, the first information can be used to indicate the relationship between all parameters in the configuration and spatial regions, or the first information can be used to indicate the association between one or more specific parameters in the configuration and spatial regions. For example, for a configuration including parameter 1, parameter 2, and parameter 3, the first information can be used to indicate that all three parameters in the configuration correspond to a certain spatial region, or the first information can be used to indicate that a specific parameter 1 in the configuration corresponds to a certain spatial region.
[0234] For example, regarding the parameters in the measurement resource configuration, taking the measurement resource configuration of the SSB used for measurement as an example, multiple SSB configurations can be provided. Each SSB configuration can include a variety of parameters, and the parameter values included in different SSB configurations are different. For example, SSB configuration 1 can correspond to spatial region 1, SSB configuration 2 can correspond to spatial region 2, SSB configuration 3 can correspond to spatial region 3, and so on.
[0235] The SSB configuration can be either a configuration of the SSB index used to indicate the SSB under test, or a configuration of the SSB pattern used to indicate the SSB under test.
[0236] For example, regarding the parameters in the measurement resource configuration, taking the configuration of the Channel State Information Reference Signal (CSI-RS) used for measurement as an example, multiple CSI-RS configurations can be provided. Each CSI-RS configuration can include a variety of parameters, and the parameter values included in different CSI-RS configurations are different. For example, CSI-RS configuration 1 can correspond to spatial region 1, CSI-RS configuration 2 can correspond to spatial region 2, CSI-RS configuration 3 can correspond to spatial region 3, and so on.
[0237] For example, regarding the parameters in the measurement event configuration, taking the measurement event as event A5 mentioned above, the measurement event configuration can be used to configure the value of the second threshold value used in event A5. For example, the second threshold value 1 can correspond to spatial region 1, the second threshold value 2 can correspond to spatial region 2, the second threshold value 3 can correspond to spatial region 3, and so on.
[0238] In some embodiments, the spatial region can be determined by a first parameter. Optionally, when the network device indicates first information to the terminal, it can indicate the spatial region to the terminal by indicating the first parameter, and the terminal can then determine the corresponding spatial region based on the first parameter indicated by the network device.
[0239] In some embodiments, the first parameter may include at least one of a reference position and / or distance threshold, a reference direction and / or angle threshold, a reference height range and / or a reference distance range.
[0240] The reference position can be any location. The reference direction can be determined by two sequentially ordered reference points. The reference direction can be represented by a ray. Optionally, the reference direction can be determined by configuring the starting point of the ray and the corresponding direction reference point, or it can be determined by a spherical coordinate system with the reference point as the origin. For example, the reference position can be used as one reference point, and another reference point can be indicated. The reference direction can then be determined based on the reference position and the indicated reference point. In this case, the reference direction can be represented by a ray originating from the reference position and containing the indicated reference point. The distance threshold can be used to measure the distance between the terminal's position and the reference position; that is, the distance threshold can be the threshold value corresponding to the distance between the terminal's position and the reference position. The angle threshold can be used to measure the angle between the direction of the terminal relative to the reference position (or the ray direction where the UE's position is located) and the reference direction; that is, the angle threshold can be the threshold value corresponding to the angle difference between the direction of the terminal's position relative to the reference position and the reference direction.
[0241] Optionally, the spatial region can be a cone, sphere, cube, or irregular shape, etc., and the embodiments disclosed herein are not limited in this respect.
[0242] In some embodiments, the first parameter may include multiple reference positions, and the terminal can determine a closed spatial region based on these multiple reference positions. The closed spatial region determined based on these multiple reference positions is a spatial region configured by the network device for the terminal.
[0243] In some embodiments, the first parameter may include multiple distance thresholds. In this case, there may be a default reference position, which may be agreed upon by the protocol or indicated by the network device. The terminal can determine a closed spatial area based on this default reference position and multiple distance thresholds. The closed spatial area determined based on the default reference position and multiple distance thresholds is a spatial area configured by the network device for the terminal.
[0244] In some embodiments, the first parameter may include a reference position and a distance threshold. Both the reference position and the distance threshold can be one or more. The terminal can determine a closed spatial region based on one or more reference positions and one or more distance thresholds. The closed spatial region determined based on one or more reference positions and one or more distance thresholds is a spatial region configured by the network device for the terminal.
[0245] In some embodiments, the first parameter may include multiple reference directions. The terminal can determine a closed spatial region based on these multiple reference directions. The closed spatial region determined based on these multiple reference directions is a spatial region configured by the network device for the terminal.
[0246] In some embodiments, the first parameter may include multiple angle thresholds. In this case, there may be a default reference position, which may be agreed upon by the protocol or indicated by the network device. The terminal can determine a closed spatial region based on this default reference position and multiple angle thresholds. The closed spatial region determined based on the default reference position and multiple angle thresholds is a spatial region configured by the network device for the terminal.
[0247] In some embodiments, the first parameter may include a reference direction and an angle threshold. Both the reference direction and the angle threshold can be one or more. The terminal can determine a closed spatial region based on one or more reference directions and one or more angle thresholds. The closed spatial region determined based on one or more reference directions and one or more angle thresholds is a spatial region configured by the network device for the terminal.
[0248] In some embodiments, the first parameter may include a reference height range, which may consist of an upper height limit and a lower height limit. Both the upper and lower height limits can be infinitely large, so as to determine a closed spatial region through the reference height range. The closed spatial region determined according to the reference height range is a spatial region configured by the network device for the terminal. The height can be altitude or ground level, and this disclosure does not limit it.
[0249] In some embodiments, the first parameter may include a reference distance range, which may consist of an upper distance limit and a lower distance limit. Both the upper and lower distance limits may be infinite. In this case, there may be a default reference position, which may be agreed upon by the protocol or indicated by the network device, so as to determine a closed spatial area through the reference distance range and the default reference position. The closed spatial area determined according to the reference distance range and the default reference position is a spatial area configured by the network device for the terminal.
[0250] In some embodiments, the first parameter may include a reference height range and a reference distance range, so as to determine a closed spatial region through the reference height range and the reference distance range. The closed spatial region determined according to the reference height range and the reference distance range is a spatial region configured by the network device for the terminal.
[0251] In some embodiments, the first parameter may include a reference position, a distance threshold, a reference direction, and an angle threshold. Based on these four parameters, a conical-like spatial region can be determined as a spatial region configured by the network device for the terminal. Referring to Figure 5, which is a schematic diagram of a spatial region according to an embodiment of this disclosure, position 501 is the reference position. The direction of the ray determined by two sequentially linked reference points (i.e., reference position 501 and position 502) is the reference direction. The distance threshold is the threshold value corresponding to the distance between the terminal's position and reference position 501. The angle threshold is the threshold value corresponding to the angle difference between the ray direction (i.e., the direction of the terminal's position relative to reference position 501) and the reference direction. These four parameters can be used to determine a conical-like spatial region.
[0252] It should be noted that the above are only some exemplary introductions of parameter combinations for determining spatial regions, and do not constitute a limitation on the embodiments of this disclosure. In more possible implementations, the parameters for determining spatial regions can have more possible combinations, and the embodiments of this disclosure do not limit this.
[0253] In some embodiments, spatial regions can be configured via events. For example, a first parameter for determining the spatial region can be indicated in a first event configuration, so that the terminal can determine different spatial regions based on the first parameter indicated in the first event configuration. The first event can be a measurement event, or it can be a specific event, but is not limited thereto. Taking a specific event as an example, a dedicated event can be set to indicate the first parameter for determining the spatial region, so that the terminal can determine different spatial regions based on the first parameter indicated by the specific event.
[0254] For example, spatial region parameters can be configured through a first event corresponding to position and angle. The first event can correspond to parameters {reference position, distance threshold, reference direction, angle threshold}. Optionally, the first event can also include information such as distance hysteresis, distance offset, angle hysteresis, and angle offset, as well as information such as trigger time, but is not limited to these.
[0255] Taking the parameters {reference position, distance threshold, reference direction, angle threshold} corresponding to the first event as an example, if the first event is used to determine the location of the terminal within this spatial region, then the first event can be: the distance between the terminal's position and the reference position is less than or equal to the distance threshold value, and the angle between the direction of the terminal's position relative to the reference position and the reference direction is less than or equal to the angle threshold value.
[0256] In addition, the first event can be configured as an event used to determine that the terminal is not in this spatial area. The first event can be: the distance between the terminal's position and the reference position is greater than or equal to a distance threshold, or the angle between the direction of the terminal's position relative to the reference position and the reference direction is greater than or equal to an angle threshold.
[0257] In some embodiments, the terminal can determine the spatial region where it is located based on its spatial location information and a first parameter corresponding to one or more spatial regions. Alternatively, for a first spatial region that is any one of the one or more spatial regions, the terminal can determine whether it is within the first spatial region based on its spatial location information and the first parameter corresponding to the first spatial region.
[0258] Taking the first parameters corresponding to the first spatial region, including reference position, distance threshold, parameter direction, and angle threshold, as an example, the terminal can determine that it is within the first spatial region if the distance between its position and the reference position meets the distance threshold and the angle between the terminal's position and the reference direction meets the angle threshold. Conversely, the terminal can determine that it is not within the first spatial region if the distance between its position and the reference position does not meet the distance threshold or the angle between the terminal's position and the reference direction does not meet the angle threshold.
[0259] Optionally, satisfying the distance threshold can be less than or equal to (i.e., not greater than) the distance threshold, and correspondingly, not satisfying the distance threshold can be greater than the distance threshold; or, satisfying the distance threshold can be less than the distance threshold, and correspondingly, not satisfying the distance threshold can be greater than or equal to (i.e., not less than) the distance threshold. Similarly, satisfying the angle threshold can be less than or equal to (i.e., not greater than) the angle threshold, and correspondingly, not satisfying the angle threshold can be greater than the angle threshold; or, satisfying the angle threshold can be less than the angle threshold, and correspondingly, not satisfying the angle threshold can be greater than or equal to (i.e., not less than) the angle threshold. This disclosure does not limit the specifics of these embodiments.
[0260] In some embodiments, when determining whether a terminal is in a certain spatial region, the terminal may be allowed to relax the decision criteria. That is, a second parameter can be configured for the terminal, which may include at least one of hysteresis, offset, and trigger time (TTT). Hysteresis may include distance hysteresis and / or angle hysteresis, and offset may include distance offset and / or angle offset, but is not limited thereto.
[0261] In some embodiments, terms such as “time,” “moment,” “point in time,” and “time location” can be used interchangeably, as can terms such as “time,” “duration,” “segment,” “time window,” and “window.”
[0262] In some embodiments, the second parameter can be configured via an event. For example, it can be indicated in the measurement event configuration, or the configuration of the second parameter can be implemented through a specific event. For example, a dedicated event can be set to indicate the second parameter, which is not limited in this disclosure.
[0263] In some embodiments, for a first spatial region that is any one of one or more spatial regions, the terminal can determine whether the terminal is in the first spatial region based on the second parameter, the terminal's spatial location information, and the first parameter corresponding to the first spatial region.
[0264] In step S4102, when the terminal enters or leaves the first spatial area, it performs a corresponding operation based on the first information.
[0265] The first spatial region can be any one of one or more spatial regions. For example, the first spatial region can be a specific spatial region among one or more spatial regions. This disclosure does not limit this.
[0266] In some embodiments, the terminal can determine whether it has entered or left a certain spatial region based on whether its current spatial region has changed. For details regarding the terminal's spatial region determination based on its own spatial region and the parameters used to determine the spatial region (including the first parameter and the second parameter), please refer to the preceding text; these details will not be repeated here.
[0267] In some embodiments, when a terminal enters a first spatial region, the terminal can perform a first operation based on the first configuration corresponding to the first spatial region in the first information.
[0268] In some embodiments, the name of the first operation is not limited, and may be, for example, "first mobility operation", "first behavior", "first mobility behavior", "first process", "first mobility process", etc.
[0269] In some embodiments, the terminal may activate the candidate cell, beam, or TCI state corresponding to the first spatial region. For example, the terminal may perform early activation on the candidate cell, beam, or TCI state corresponding to the first spatial region.
[0270] In some embodiments, the terms "cell", "component carrier (CC)", "frequency carrier", and "carrier frequency" can be used interchangeably.
[0271] In some embodiments, the terms “beam”, “beam width”, “beam angular degree”, “precoding”, “precoder”, “weight”, “precoding weight”, “quasi-co-location (QCL)”, “transmission configuration indication (TCI) status”, “spatial relation”, “spatial domain filter”, “transmission power”, “phase rotation”, “antenna port”, “antenna port group”, “layer”, “the number of layers”, “rank”, “resource”, “resource set”, “resource group”, “antenna”, “antenna element”, and “panel” can be used interchangeably.
[0272] In some embodiments, the terminal may synchronize candidate cells corresponding to the first spatial region. For example, the terminal may perform early uplink synchronization on candidate cells corresponding to the first spatial region.
[0273] In some embodiments, the terminal can obtain the Timing Advance (TA) value of the candidate cell corresponding to the first spatial region. Furthermore, the terminal can also maintain the TA value of the candidate cell corresponding to the first spatial region. For example, the terminal can obtain and maintain the TA value when performing early uplink synchronization on the candidate cell corresponding to the first spatial region.
[0274] In some embodiments, the terminal can obtain the TCI status / beam TA value of the candidate cell corresponding to the first spatial region. Furthermore, the terminal can also maintain the TCI status / beam TA value of the candidate cell corresponding to the first spatial region. For example, the terminal can obtain and maintain the TA value when performing early uplink synchronization on the candidate cell corresponding to the first spatial region.
[0275] In some embodiments, the terminal can obtain the TA value of the candidate cell or the TCI status / beam TA value of the candidate cell through the advance random access channel (RACH). For example, the TA value of the candidate cell or the TCI status / beam TA value of the candidate cell can be obtained when sending a preamble to the candidate cell.
[0276] In some embodiments, the terminal can obtain the TA value of the candidate cell or the TA value of the candidate cell's TCI status / beam by calculating the TA based on the UE measurement or obtaining the TA based on the UE.
[0277] In some embodiments, the terminal may initiate measurements of candidate cells or beams corresponding to a first spatial region.
[0278] In some embodiments, the terminal may trigger and / or execute measurements based on the measurement resource configuration corresponding to the first spatial region.
[0279] Taking the configuration of measurement resources for SSB used for measurement as an example, the measurement resource configuration is an SSB configuration, and the SSB configuration is a configuration for indicating the SSB index or SSB pattern of the SSB to be measured. Then the terminal can trigger and / or execute the measurement based on the SSB index or SSB pattern indicated by the SSB configuration corresponding to the first spatial region.
[0280] Taking the configuration of measurement resources for CSI-RS as an example, if the measurement resources are configured as CSI-RS, the terminal can trigger and / or execute measurements based on the CSI-RS configuration corresponding to the first spatial region.
[0281] In some embodiments, the terminal may trigger and / or execute measurement reporting based on the measurement event configuration or measurement reporting configuration corresponding to the first spatial region.
[0282] In some embodiments, the terminal may configure to trigger and / or execute measurement reporting based on the measurement event corresponding to the first spatial region. For example, the terminal may evaluate event A5 based on the second threshold value corresponding to the first spatial region and trigger the corresponding measurement reporting.
[0283] In some embodiments, the measurement results reported by the terminal can be used to assist the network device in determining whether to perform cell handover, or the terminal can determine whether to perform cell handover based on the measurement results itself. This disclosure does not limit this aspect.
[0284] In some embodiments, the terminal may send its device status to the network device, wherein the device status may include at least one of location, altitude, and speed. That is, the terminal may trigger location reporting, altitude reporting, speed reporting, etc.
[0285] In some embodiments, the terminal can perform mobility management operations on candidate cells or beams corresponding to the first spatial region. Mobility management can include any one or more of the following: handover, conditional handover (CHO), conditional primary / secondary cell addition / change (CPAC, also known as CPA and CPC), condition-triggered mobility, L1 / L2-triggered mobility (LTM), and conditional LTM (C-LTM). For example, the terminal can implement spatial region-triggered mobility management operations based on first information configured in the network device. For instance, when the terminal's location meets the corresponding spatial region conditions, it can be considered that the terminal has entered the first spatial region. At this time, the terminal can perform cell handover (or cell switch) on candidate cells or beams corresponding to the first spatial region to access the corresponding candidate cell or beam.
[0286] In some embodiments, for any one or more of condition-triggered mobility, CHO, CPAC, and C-LTM, the terminal can implement a spatial region-based mobility management operation based on first information configured by the network device. The implementation of the spatial region-based mobility management operation based on the first information includes configuring a spatial region as a condition for mobility based on the first information.
[0287] For example, when the location of the terminal meets the conditions of the corresponding spatial area, the terminal can be considered to have entered the first spatial area. At this time, the terminal can perform corresponding mobility operations on the candidate cell or beam corresponding to the first spatial area, such as any one or more of CHO, CPAC, and C-LTM, to access the corresponding candidate cell or the corresponding beam.
[0288] For example, the network side can configure spatial area conditions to be used in conjunction with measurement result-based conditions. That is, when both spatial area conditions and measurement result-based conditions are met, the terminal will then perform the corresponding mobility operation, such as any one or more of CHO, CPAC, and C-LTM, to access the corresponding candidate cell or the corresponding beam.
[0289] For example, the conditions for determining whether a device is within a certain spatial region can be configured using a set of parameters: {reference position, distance threshold, reference direction, angle threshold}. The conditions for being within a spatial region are: the distance between the terminal's position and the reference position is less than or equal to the distance threshold, and the angle between the terminal's position's direction relative to the reference position and the reference direction is less than or equal to the angle threshold. Alternatively, the conditions for not being within a spatial region are: the distance between the terminal's position and the reference position is greater than or equal to the distance threshold, or the angle between the terminal's position's direction relative to the reference position and the reference direction is greater than or equal to the angle threshold.

[0303] Conditional event A3: The candidate offset for conditional reconfiguration is better than PCell or PSCell;
[0304] Conditional event A4: The performance of the candidate for conditional reconfiguration is better than the threshold value, wherein conditional event A4 can also be applied to the current PSCell of the conditional handover (CHO) with a candidate secondary cell group (SCG) (i.e., when it is configured as a candidate PSCell for evaluation by conditional event A4).

[0307] Conditional event D2: The distance between the terminal and the serving cell moving reference location determined by the movingReferenceLocation in SIB19 and its corresponding satellite ephemeris and epoch time broadcast is greater than the configured ThreshFromReference1, and the distance between the terminal and the reference location of the conditional reconfiguration candidate provided by MeasObjectNR and its corresponding moving reference location determined by its satellite ephemeris and epoch time becomes less than the configured ThreshFromReference2;
[0308] Conditional event T1: The measurement time at the terminal is greater than the configured threshold T1, but less than the sum of the threshold T1 and the duration.

[0311] Event I1: Interference exceeds the absolute threshold (For Event I1, the measurement report event is based on Channel Quality Indicator (CLI) measurements, which can be derived from Sounding Reference Signal-Reference Signal Received Power (SRS-RSRP) or Received Signal Strength Indicator (CLI-RSSI)).

[0320] In some embodiments, the name of cell-level beam management is not limited, and may include, for example, condition-triggered mobility management, condition-triggered L1 mobility management, condition-triggered beam-level mobility management, etc.
[0321] In some embodiments, the judgment condition for whether or not to switch spatial areas can be used in conjunction with the judgment condition based on measurement results. That is, when the terminal determines that it has entered the first spatial area, it can perform cell mobility management operation on the candidate cell or beam corresponding to the first spatial area based on the measurement results of the candidate cell or beam corresponding to the first spatial area. The corresponding cell mobility management operation will be triggered only when both the spatial area condition and the condition based on the measurement results meet the requirements.

[0345] According to the solution provided in the embodiments of this disclosure, the terminal can determine its spatial area based on its spatial location information, thereby performing mobility-related operations. Different spatial areas correspond to different mobility configurations / cells / beams. When the terminal is in a specific spatial area, the terminal performs a corresponding first mobility operation for the mobility configuration / cell / beam corresponding to this spatial area. When the terminal leaves the corresponding spatial area, the terminal performs a corresponding second mobility operation for the mobility configuration / cell / beam corresponding to this spatial area.
[0346] In some embodiments, the network side configures different spatial regions (3D spatial regions) for different mobility configurations / cells / beams. The specific spatial region can be determined by parameters such as one or more reference positions, reference distances, and reference directions in space. For example, this spatial region can be a defined spatial region such as a cone, sphere, cube, or irregular shape.
[0347] In some embodiments, the network side configures first information for the terminal, wherein the first information includes configuration information required for the terminal to perform mobility operations (or mobility behaviors or mobility processes), and configuration information of mobility candidate cells (the network side may simultaneously configure multiple candidate cells and their corresponding configurations required for the first mobility operation for the terminal).
[0348] In some embodiments, the network side configures different spatial regions (3D spatial regions) for different mobility configurations / cells / beams, wherein the spatial region can be configured by any one or more of the following parameters: reference position (3D spatial position) and / or distance threshold; reference direction and / or angle threshold; reference height range and / or reference distance range.
[0349] The reference direction can be represented by a ray, which can be determined by setting the starting point of the ray and the corresponding direction reference point, or by using a spherical coordinate system with the reference point as the origin.
[0350] For example, a spatial region can be determined based on {reference position, distance threshold, reference direction, angle threshold}. Based on these four parameters, a spatial region resembling a cone can be defined.
[0351] In some embodiments, in addition to being represented by specific parameters, spatial regions can also be configured through specific events.
[0352] In some embodiments, the spatial region parameter may correspond to a position- and angle-based event, which may correspond to any one or more of the above parameters. Optionally, the event may also include information such as distance hysteresis, distance offset, angle hysteresis, and angle offset, as well as trigger time.
[0353] Taking this event corresponding to the parameters {reference position, distance threshold, reference direction, angle threshold} as an example, this event can be used to determine that the terminal is within a certain spatial region. This event can be defined as follows: the distance between the terminal's position and the reference position is less than / or less than or equal to the distance threshold, and the direction of the terminal's position relative to the reference position is less than / or less than or equal to the angle threshold. Alternatively, this event can be used to determine that the terminal is not within a certain spatial region. This event can be defined as follows: the distance between the terminal's position and the reference position is greater than / or greater than or equal to the distance threshold, or the direction of the terminal's position relative to the reference position is greater than / or greater than or equal to the angle threshold.
[0354] In some embodiments, different mobility configurations / cells / beams correspond to different spatial regions (3D spatial regions), including any one or more of the following:
[0355] The network side configures the association between measurement resources and spatial regions. Different spatial regions correspond to different measurement resources. For example, different spatial regions correspond to different SSBs.
[0356] The network side configures the association between measurement events and spatial regions. Different spatial regions correspond to different measurement event configurations. The different measurement event configurations may include configuration information related to spatial region parameters, or spatial region parameters may also be used as one or more specific measurement events, which can be configured together with measurement-based events.
[0357] The network is configured to associate different cell / beam / TCI states with spatial regions. Different spatial regions correspond to different cell / beam / TCI states. For example, different spatial regions correspond to different candidate cell beams.
[0358] In the above configuration, the same spatial region can correspond to multiple measurement resources, multiple measurement events, and multiple cells / beams / TCI states simultaneously; or, one measurement resource, one measurement event, and one cell / beam / TCI state can also correspond to multiple spatial regions simultaneously.
[0359] In some embodiments, the terminal can determine its spatial region based on its spatial location information. When the UE enters a specific spatial region, it performs mobility-related operations including any one or more of the following:
[0360] The terminal pre-activates the execution of candidate cells / beams / TCI states corresponding to the spatial region;
[0361] The terminal performs advance uplink synchronization with candidate cells corresponding to the spatial region, obtains TA, and maintains TA values;
[0362] The terminal initiates measurement of the candidate cells / beams corresponding to the spatial region;
[0363] The terminal performs measurements on the measurement resources corresponding to the spatial region and obtains the measurement results;
[0364] The terminal performs corresponding measurement reporting based on the spatial region;
[0365] The terminal triggers location reporting, altitude reporting, speed reporting, etc.
[0366] The network side can configure mobility triggered by spatial area conditions (e.g., CHO, C-LTM, etc.) for the terminal. For example, when the terminal's location meets the corresponding spatial area conditions, the UE performs a cell switch on the candidate cell / beam corresponding to the spatial area conditions, switching to the corresponding candidate cell / accessing the corresponding beam. Optionally, the spatial area conditions can also be used in conjunction with measurement result-based conditions. That is, the terminal will only trigger CHO, C-LTM, etc., when both the spatial area conditions and the measurement result-based conditions are met.
[0367] In some embodiments, the terminal determines its spatial region based on its spatial location information. When the terminal leaves the specific spatial region, it performs mobility-related operations including any one or more of the following:
[0368] The terminal deactivates the candidate cell / beam / TCI state corresponding to the spatial region (if it was previously activated);
[0369] The terminal deletes the TA value maintained for the candidate cells corresponding to the spatial region (if it existed before);
[0370] The terminal stops measuring the candidate cells / beams corresponding to the spatial region;
[0371] The terminal stops measuring the measurement resources corresponding to the spatial region.
[0372] In some embodiments, the above measurements may include LTM measurements, RRM measurements, etc.
[0373] In some embodiments, an LTM measurement can be any one or more of the following: an L1 measurement, a CSI measurement, an LTM measurement, an L2 measurement, a measurement with results reported via UCI, or a measurement with results reported via MAC CE.
[0374] In some embodiments, RRM measurements may also be referred to as L3 measurements, which may include measurements that report results via RRC.
[0375] C-LTM can be referred to as any one or more of the following: condition-triggered mobility, condition-triggered L1 mobility, and condition-triggered beam-level mobility.
