Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an information transmission method, apparatus, device, non-transiently readable storage medium, and chip. Background Technology

[0002] Synchronization signals (blocks) can be used by the UE (User Equipment) for at least one of the following processes: cell search, cell timing synchronization, L1 / L3 (i.e., Layer 1 or Layer 3) measurement, beam management, etc. For example, the synchronization signal block for NR (New Radio) is the SSB (Synchronization Signal / PBCH block), which can include PSS (Primary Synchronization Signal), SSS (Secondary Synchronization Signal), and PBCH (Physical Broadcast Channel). The UE can use the SSB for downlink time and frequency synchronization to obtain the Physical Cell Identity (PCID) and complete the cell search process. The UE can also use the SSB to complete at least one of the following processes: L1 / L3 measurement, beam management, RLM (Radio Link Monitoring), BFD (Beam Failure Detection), etc. For all of the above, the cell needs to send the corresponding synchronization signal (block). However:

[0003] In existing technologies, the synchronization signals (blocks) of SpCell (Special Cell) need to be sent at relatively dense intervals (e.g., 20ms), which increases network-side power consumption, resulting in higher power consumption. SpCell includes PCell (Primary Cell) and PSCell (Primary Secondary Cell).

[0389] To address the aforementioned technical problems, considering that: to reduce network-side overhead, SpCell can send only sparse synchronization signals (blocks), or even none at all, and only send synchronization signals (blocks) on demand, thereby reducing latency in related processes, such as handover or PSCell addition / change (i.e., PSCell addition or change), the present application provides an information transmission method, specifically a method for obtaining synchronization signals (blocks), for the UE to obtain synchronization signals (blocks) in a timely manner, thereby reducing latency in handover, PSCell addition / change, and reconstruction (during RRC (Radio Resource Control) processes). This solution mainly involves:

[0390] The network side sends configuration and / or status information of the on-demand transmission of synchronization signals (blocks) for the target cell or candidate cell to the UE; this corresponds to the first information received by the terminal from the first network device for the first cell; the first information includes: at least one set of configuration information for the first signal, and at least one of the status information of the first signal. Based on the information, the UE determines the synchronization signal (block) in the first process, that is, determines the on-demand transmission SSB in the process for reception; the first process may include at least one of the following processes: handover; PCellchange; CHO (Conditional handover); LTM (L1 / L2 Triggered Mobility); PSCell addition; PSCell change; CPA (Conditional PSCellAddition); CPC (Conditional PSCell Change); reconstruction process, i.e., RRC reconstruction process. The UE determining the content of the synchronization signal (block) is equivalent to the terminal determining the transmission information of the first signal in the first process based on the first information.

[0411] 6) Indication information 1, which can be used to indicate that it is a synchronization signal (block) to be sent on demand; it can correspond to the first indication information above, and is used to indicate that the first signal is a first signal to be sent on demand;

[0412] 7) Indication information 2 can be used to indicate the process type of effective application of the synchronization signal (block); it can correspond to the second indication information mentioned above, and is used to indicate the communication process corresponding to the first signal;

[0413] The process type may include at least one of the following:

[0417] 8) Activation or deactivation status indicator, used to indicate whether the current synchronization signal (block) configuration information is activated, or to indicate whether the current synchronization signal (block) is being transmitted; can correspond to the above activation or deactivation status indicator, used to indicate whether the configuration information is activated or deactivated;

[0418] The phrase "Current synchronization signal (block) is being sent" corresponds to activating the current synchronization signal (block) configuration information, while "Current synchronization signal (block) is not being sent" corresponds to deactivating the current synchronization signal (block) configuration information.

[0419] In this scheme, the configuration of the synchronization signal (block) sent on demand can include at least one configuration, which is not limited here.

[0420] 3. Based on 2, regarding the time-domain information, if the target cell is a PCell, the timing (i.e., time) of the source PCell or one of the source serving cells (among all source serving cells) can be used as a reference; corresponding to the case where the target cell is the PCell, the time-domain information is determined based on the time of the source PCell or the source serving cell.

[0421] If the target cell is a PSCell, the timing (i.e., time) of the PCell, the source PSCell, or one of the source serving cells (among all source serving cells) can be used as a reference; corresponding to the case where the target cell is a PSCell, the time domain information is determined based on the time of the PCell, the source PSCell, or the source serving cell.

[0422] 4. Based on 1, the status information may include an activation or deactivation command sent by the network side; this command may indicate which set of configuration information (or multiple sets of configuration information) to activate or deactivate, such as sending a command to the UE to activate one or more CHO candidate cell synchronization signals (blocks) in Embodiment 3 below; optionally, the status information may be carried through RRC, MAC CE (Medium Access Control-Control Element), or L1. Specifically:

[0423] The status information (such as the information within the activation (or deactivation) command) may further indicate which or which first cells to activate (or deactivate), and may even further indicate which or which configuration information in the first cells to activate (or deactivate) (in the case of multiple sets of configuration information for the first signal); corresponding to the above status information may also include at least one of the following: the first identifier of the first cell corresponding to the third indication information, and the second identifier of the configuration information corresponding to the third indication information.

[0424] 5. Based on 1, the UE can send information to the network side to indicate that the synchronization signal (block) no longer needs to be sent on demand; this information is an indication that can be used to notify the network side to stop the transmission of the synchronization signal (block) sent on demand; it can correspond to sending the second information to the network device where the first cell is located, the second information being used to request the cessation of the transmission of the first signal.

[0425] Furthermore, the UE may carry the corresponding target cell identifier in this information; it may also carry the cell identifier of the second cell corresponding to the second information mentioned above, and the second cell may include the target cell.

[0426] 6. Based on 2, the UE can apply on-demand synchronization signals (blocks) during the CHO condition evaluation phase and / or the CHO handover execution phase; that is, the UE receives on-demand synchronization signals (blocks) according to the configuration.

[0427] 7. Based on 2, the UE can apply on-demand synchronization signals (blocks) during the LTM L1 / L3 measurement phase and / or the LTM cell switch phase; that is, the UE receives on-demand synchronization signals (blocks) according to the configuration.

[0428] 8. Based on 1, the UE determines whether to apply on-demand transmission of synchronization signals (blocks) in a relevant process based on network-side indication information (which may be information other than the aforementioned indication information 2); this may correspond to receiving the third information sent by the first network device; the third information is used to indicate whether the terminal receives the first signal in a target process included in the first process; the target process is at least one process included in the first process; if the third information indicates reception, the first signal is received in the target process according to the transmission information.

[0429] Optionally, during one or more stages of the above process, the UE may perform fast measurement based on the activated synchronization signal (block) (which may correspond to the signal measurement performed according to the configuration information mentioned above); Optionally, the UE may perform fast measurement for a certain period of time, for example, the duration of fast measurement is T (T may be based on network-side configuration or protocol predefined); This may correspond to the signal measurement performed according to the target time information and the configuration information (or, within the target duration or target time period, the signal measurement performed according to the configuration information), but is not limited thereto.

[0430] Network side:

[0431] 1. Send the configuration information and / or status information to the UE; this may correspond to the first network device sending the first information to the terminal. Based on the configuration information and / or status information, the target cell sends a synchronization signal (block); this may correspond to the first network device or the second network device sending the first signal according to the first information.

[0432] 2. Based on 1, the configuration information and / or status information can be provided by the target RAN (Radio Access Network) side node (i.e., the second network device mentioned above) where the target cell is located to the RAN side node (i.e., the first network device mentioned above) where the source PCell or source PSCell is located; the first network device can receive the first information sent by the second network device.

[0433] 3. Based on 2, the target RAN side node where the target cell is located can provide relevant feedback based on the request of the RAN side node where the source PCell or source PSCell is located; it can receive the first request sent by the first network device in response to the second network device mentioned above; and send the first information to the first network device according to the first request.

[0434] It should be noted that the relevant content on the terminal side and the network side can be referred to each other, and the repeated parts will not be repeated.

[0435] The following provides a specific example illustrating this solution. The embodiments described below are applicable to both 5G and subsequent evolution versions, and are not limited to any particular version.

[0436] Example 1: UE determines synchronization signal block transmission in a handover (also known as PCell change) scenario;

[0437] The RAN-side node (i.e., the network device) can perform the following operations:

[0438] During the handover preparation process, the source RAN-side node (corresponding to the first network device mentioned above) sends the configuration information of the on-demand synchronization signal (block) of the target PCell to the UE; of course, it can also send the configuration information of the on-demand synchronization signal (block) of other cells at the same time. Among them:

[0439] 1. Optionally, the configuration information may be provided by the target PCell (or the RAN-side node where the target PCell resides, corresponding to the second network device mentioned above). If the source RAN-side node and the target RAN-side node are different nodes, the target RAN-side node may send the configuration information to the source RAN-side node through a relevant interface. Alternatively, the target PCell or the target RAN-side node may send information to the source RAN-side node, which will then generate the configuration information based on its own timing information and send it to the UE. This is not limited here.

[0440] 2. The configuration information may be included in an RRC (Radio Resource Control) message, for example, in an RRC reconfiguration message. Specifically, the configuration information may be included in the configuration of the target PCell for the handover (or PCell change) process; this configuration may be sent from the target PCell to the source PCell.

[0441] 3. The synchronization signal (block) configuration information may include one or more of the following configurations:

[0442] 1) Frequency domain information;

[0443] 2) Time domain information, which may include one or more of the following: period, duration, offset, etc. This time domain information can be used to calculate the possible time domain location of the synchronization signal (block), wherein the time domain information can be referenced to the timing of the source PCell or one of the source serving cells;

[0444] 3) Spatial information, such as on which beams the synchronization signal (block) is transmitted;

[0445] 4) The number of repetitions can be used to inform the UE of the expiration time of the synchronization signal (block);

[0446] 5) Duration, which can be used to inform the UE of the expiration time of the synchronization signal (block);

[0447] 6) Indication information 1, which can be used to indicate that it is a synchronization signal (block) sent on demand;

[0448] 7) Indication information 2 can be used to indicate that the synchronization signal (block) is valid during the switching (or PCell change) process.

[0449] Correspondingly, the target PCell (or the RAN-side node where the target PCell resides) can send the synchronization signal (block) based on the configuration information in the above steps. Optionally, the target PCell can determine when to stop sending the synchronization signal (block) based on the configuration information in the above steps (such as the number of repetitions and the duration). The target PCell can also stop sending the synchronization signal (block) after receiving an RRC reconfiguration completion message or handover completion indication from the UE.

[0450] UE side:

[0451] The UE receives at least the on-demand synchronization signal (block) configuration information for the target PCell. The UE applies this synchronization signal (block) configuration information during handover (or PCell change). Specifically, the UE can obtain the synchronization signal (block) of the target PCell based on the synchronization signal (block) configuration information.

[0452] The network side can provide the UE with synchronization signals (blocks) to be sent on demand during the handover (or PCell change) process. The synchronization signals (blocks) can be denser in the time domain, frequency domain and / or spatial domain, or more targeted (e.g., sending synchronization signals (blocks) on certain beams based on the UE's current location), thereby helping the UE to quickly obtain synchronization signals (blocks) during the handover (or PCell change) process and reducing the latency of the handover (or PCell change) process.

[0453] The above process can also be applied to scenarios such as CHO (Conditional Handover) and LTM (L1 / L2 Triggered Mobility). In the CHO scenario, the RAN-side node provides the UE with the synchronization signal (block) configuration information corresponding to the CHO candidate cell. In the LTM scenario, the RAN-side node provides the UE with the synchronization signal (block) configuration information corresponding to the LTM candidate cell.

[0454] Example 2: Determining the configuration of synchronization signal blocks to be sent on demand in the PSCell addition or PSCell change scenario;

[0455] The RAN-side node (i.e., the network device) can perform the following operations:

[0456] During PSCell addition (also known as Secondary Node Addition) and / or PSCellchange, the RAN-side node sends the on-demand synchronization signal (block) configuration information of the target PSCell to the UE; it can also send the on-demand synchronization signal (block) configuration information of other cells at the same time. Among these:

[0457] 1. Optionally, the configuration information may be provided by the target PSCell (or the RAN-side node where the target PSCell is located, corresponding to the second network device mentioned above). If the RAN-side node (corresponding to the first network device mentioned above) that sends the configuration to the UE is a different node from the target RAN-side node, the target RAN-side node may send the configuration information to the RAN-side node that sends the configuration to the UE through a relevant interface.

[0458] 2. The configuration information may be included in the RRC message, for example, in the RRC reconfiguration message. Specifically, the configuration information may be included in the configuration of the target PSCell for PSCell addition (also known as Secondary Node Addition) and / or PSCell change scenarios; this configuration may be sent from the target PSCell and / or PCell to the source PSCell.

[0459] 3. The synchronization signal (block) configuration information may include one or more of the following configurations:

[0460] 1) Frequency domain information;

[0461] 2) Time domain information, which may include one or more of the following: period, duration, offset, etc. This time domain information can be used to calculate the possible time domain location of the synchronization signal (block). The time domain information can be referenced by the timing of the PCell or the source PSCell, or one of the source serving cells.

[0462] 3) Spatial information, such as on which beams the synchronization signal (block) is transmitted;

[0463] 4) The number of repetitions can be used to inform the UE of the expiration time of the synchronization signal (block);

[0464] 5) Duration, which can be used to inform the UE of the expiration time of the synchronization signal (block);

[0465] 6) Indication information 1 can be used to indicate that it is a synchronization signal (block) sent on demand.

[0466] 7) Indication information 2 can be used to indicate that the synchronization signal (block) is valid in PSCell addition (also known as Secondary Node Addition) and / or PSCell change scenarios.

[0467] Correspondingly, the target PSCell (or the RAN-side node where the target PSCell resides) can send the synchronization signal (block) based on the configuration information in the above steps. Optionally, the target PSCell can determine when to stop sending the synchronization signal (block) based on the configuration information in the above steps (such as the number of repetitions and the duration). The target PSCell can also stop sending the synchronization signal (block) after receiving an RRC reconfiguration completion message or a synchronization process completion message or other relevant indication information (such as information indicating that it no longer needs to send the synchronization signal (block) on demand) from the UE.

[0468] UE side:

[0469] The UE receives at least the on-demand synchronization signal (block) configuration information for the target PSCell. The UE applies this synchronization signal (block) configuration information during PSCell addition (also known as Secondary Node Addition) and / or PSCell change processes. Specifically, the UE can obtain the synchronization signal (block) for the target PSCell based on the synchronization signal (block) configuration information.

[0470] Optionally, after completing the PSCell addition (also known as Secondary Node Addition) and / or PSCell change, the UE may send information (corresponding to the second information mentioned above) to the target PSCell or the RAN-side node where the target PSCell resides, indicating that it no longer needs to send synchronization signals (blocks) on demand. Furthermore, the UE may further carry the corresponding target cell identifier.

[0471] The above process can also be applied to processes such as CPA (Conditional PSCell Addition) and CPC (Conditional PSCell Change).

[0472] The network side can provide the UE with on-demand synchronization signals (blocks) during PSCell addition, PSCell change, CPA, CPC and other processes, thereby assisting the UE to quickly obtain synchronization signals (blocks) during the process and reducing the latency of the corresponding process.

[0473] Example 3: In the CHO scenario, the network side activates synchronization signal block transmission on demand;

[0474] The RAN-side node (i.e., the network device) can perform the following operations:

[0475] The RAN-side node sends CHO-related configuration information to the UE. This information may include CHO candidate cell configuration information, CHO execution conditions, and on-demand synchronization signal (block) configuration information for CHO candidate cells.

[0476] The synchronization signal (block) configuration information may include one or more of the following configurations:

[0477] 1) Frequency domain information;

[0478] 2) Time domain information, which may include one or more of the following: period, duration, offset, etc. This time domain information can be used to calculate the possible time domain location of the synchronization signal (block), wherein the time domain information is referenced to the timing of the source PCell or one of the source serving cells;

[0479] 3) Spatial information, such as on which beams the synchronization signal (block) is transmitted;

[0480] 4) The number of repetitions can be used to inform the UE of the expiration time of the synchronization signal (block);

[0481] 5) Duration, which can be used to inform the UE of the expiration time of the synchronization signal (block);

[0482] 6) Indication information 1, which can be used to indicate that it is a synchronization signal (block) sent on demand;

[0483] 7) Indication information 2 can be used to indicate that the synchronization signal (block) is valid during the CHO process; further, it can further indicate whether the CHO process includes a CHO condition assessment and / or a CHO switch execution phase;

[0484] 8) Activation or deactivation status indicator, which can be used to indicate whether the current synchronization signal (block) configuration information is activated (or whether the current synchronization signal (block) is being sent).

[0485] There may be multiple CHO candidate cells; in addition, a CHO candidate cell may also include multiple synchronization signal (block) configuration information (i.e., multiple sets of configurations), corresponding to different synchronization signal (block) configurations. If the status indication information of the synchronization signal (block) configuration corresponding to a certain CHO candidate cell is active, the corresponding CHO candidate cell (which may correspond to the first cell mentioned above) sends the corresponding synchronization signal (block).

[0486] Optionally, the subsequent RAN-side node (where the source PCell is located) can send an activation command (block) for one or more CHO candidate cells to the UE based on an internal algorithm (e.g., based on measurement reports reported by the UE to determine the target range where the UE may move). (This can correspond to the activation command sent by the network side mentioned above.) Optionally, it can be carried through RRC, MAC CE (Medium Access Control-Control Element), or L1. Correspondingly, the corresponding CHO candidate cell sends an activation synchronization signal (block). Optionally, if the RAN-side node where the source PCell is located is different from the RAN-side node where the CHO candidate cell is located, the RAN-side node where the CHO candidate cell is located can send the activation indication to the RAN-side node where the source PCell is located through a relevant interface; alternatively, the RAN-side node where the CHO candidate cell is located can provide activation or deactivation indications to the peer (i.e., the RAN-side node where the source PCell is located) based on a request from the RAN-side node where the source PCell is located.

[0487] Optionally, the RAN-side node can subsequently determine that the UE may move out of the target range based on internal algorithms (such as the number of repetitions and duration in the configuration, or the measurement report reported by the UE), or stop sending synchronization signals (blocks) when it confirms that the UE has completed the CHO (e.g., received a handover completion indication sent by the UE to the target PCell). Optionally, the RAN-side node can send a deactivation synchronization signal (block) command to the UE (which may correspond to the deactivation command sent by the network side mentioned above).

[0488] UE side:

[0489] The UE receives CHO configuration information, which includes the configuration information of synchronization signals (blocks) to be sent on demand for CHO candidate cells.

[0490] The UE can combine the activation or deactivation status indication in the CHO configuration information and / or the activation / deactivation synchronization signal (block) command received subsequently (which may correspond to the above status information) to determine the active synchronization signal (block) in the CHO candidate cell.

[0491] Optionally, the UE may apply the activated synchronization signal (block) during the CHO condition evaluation phase and / or the CHO handover execution phase. Optionally, whether to apply it to the CHO condition evaluation phase and / or the CHO handover execution phase may be based on network-side indication; it may correspond to receiving the third information sent by the first network device as described above; the third information is used to indicate whether the terminal receives the first signal in a target process included in the first process; the target process is at least one process included in the first process; if the third information indicates reception, the first signal is received in the target process according to the transmission information.

[0492] Optionally, during one or more stages of the above process, the UE can perform fast measurement based on the activated synchronization signal (block) configuration (which corresponds to the signal measurement performed according to the configuration information mentioned above. Since the network side can send the activated synchronization signal (block) in a shorter time or send the synchronization signal (block) more frequently, the UE can detect the synchronization signal (block) faster and obtain the measurement result quickly when performing measurement based on this configuration); Optionally, the UE can perform fast measurement for a certain period of time, for example, the duration of fast measurement is T (T can be based on network side configuration or protocol predefined).

[0493] In this embodiment, the network side (which may correspond to the first network device or the second network device mentioned above) can send synchronization signals (blocks) as needed during the CHO process. This reduces the power consumption of the network side and also helps the UE to quickly obtain synchronization signals (blocks) during the CHO process, thereby reducing CHO latency.

[0494] Example 4: In the LTM scenario, the network side activates synchronization signal block transmission on demand;

[0495] The RAN-side node (i.e., the network device) can perform the following operations:

[0496] The RAN-side node sends LTM candidate information to the UE, which may include the on-demand synchronization signal (block) configuration information of the LTM candidate cell.

[0497] The synchronization signal (block) configuration information may include one or more of the following configurations:

[0498] 1) Frequency domain information;

[0499] 2) Time domain information, which may include one or more of the following: period, duration, offset, etc. This time domain information can be used to calculate the possible time domain location of the synchronization signal (block), wherein the time domain information is referenced to the timing of the source PCell or one of the source serving cells;

[0500] 3) Spatial information, such as on which beams the synchronization signal (block) is transmitted;

[0501] 4) The number of repetitions can be used to inform the UE of the expiration time of the synchronization signal (block);

[0502] 5) Indication information 1 can be used to indicate that it is a synchronization signal (block) sent on demand;

[0503] 6) Indication information 2 can be used to indicate that the synchronization signal (block) is valid during the LTM process; further, it can indicate whether it is applied to the LTM L1 / L3 measurement and / or the execution of the LTM cell switch phase.

[0504] 7) Activation or deactivation status indicator, which can be used to indicate whether the current synchronization signal (block) configuration information is activated (or whether the current synchronization signal (block) is being sent).

[0505] There may be multiple LTM candidate cells; furthermore, an LTM candidate cell may also include multiple synchronization signal (block) configuration information (i.e., multiple sets of configurations), corresponding to different synchronization signal (block) configurations. If the status indication information of the synchronization signal (block) configuration corresponding to a certain LTM candidate cell is active, the corresponding LTM candidate cell (which may correspond to the first cell mentioned above) sends the corresponding synchronization signal (block).

[0506] Optionally, assuming the RAN side node where the LTM source cell is located is the same as the RAN side node where the LTM candidate cell is located, the RAN side node can subsequently send an activation command (block) for one or more LTM candidate cell synchronization signals to the UE based on an internal algorithm (e.g., based on the measurement report reported by the UE to determine the target range where the UE may move). (This can correspond to the activation command sent by the network side mentioned above.) Optionally, this can be carried via MAC CE or L1. Correspondingly, the corresponding LTM candidate cell sends an activation synchronization signal (block).

[0507] Optionally, the RAN-side node can determine that the UE may move out of the target range based on internal algorithms (such as the number of repetitions in the configuration or the measurement report reported by the UE), or stop sending synchronization signals (blocks) when it confirms that the UE has completed LTM (such as receiving a handover completion indication sent by the UE to the target PCell). Optionally, the RAN-side node can send a deactivation synchronization signal (block) command to the UE (which can correspond to the deactivation command sent by the network side mentioned above).

[0508] It should be noted that the operations performed by the RAN side node in this embodiment can also be similarly applied to schemes where the RAN side node where the LTM source cell is located is different from the RAN side node where the LTM candidate cell is located. For example, the RAN side node where the LTM source cell is located sends a command to the UE to activate one or more LTM candidate cell synchronization signals (blocks), and the RAN side node where the LTM candidate cell is located stops sending synchronization signals (blocks) based on its internal algorithm, etc., without limitation.

[0509] UE side:

[0510] The UE receives LTM configuration information, which includes the configuration information of synchronization signals (blocks) to be sent on demand by LTM candidate cells.

[0511] The UE can combine the activation or deactivation status indication in the LTM configuration information and / or the activation / deactivation synchronization signal (block) command received subsequently (which may correspond to the above status information) to determine the active synchronization signal (block) in the LTM candidate cell.

[0512] Optionally, the UE may apply an activated synchronization signal (block) during the LTM L1 / L3 measurement phase and / or the LTM cell switch phase. Optionally, the UE determines whether to apply the on-demand synchronization signal (block) during the phase based on network-side indication; this may correspond to receiving the third information sent by the first network device as described above; the third information is used to indicate whether the terminal receives the first signal in a target process included in the first process; the target process is at least one process included in the first process; if the third information indicates reception, the first signal is received in the target process according to the transmission information.

[0513] Optionally, during one or more stages of the above process, the UE can perform fast measurement based on the activated synchronization signal (block) configuration (which corresponds to the signal measurement performed according to the configuration information mentioned above. Since the network side can send the activated synchronization signal (block) in a shorter time or send the synchronization signal (block) more frequently, the UE can detect the synchronization signal (block) faster and obtain the measurement result quickly when performing measurement based on this configuration); Optionally, the UE can perform fast measurement for a certain period of time, for example, the duration of fast measurement is T (T can be based on network side configuration or protocol predefined).

[0514] In this embodiment, the network side (which may correspond to the first network device or the second network device mentioned above) can send synchronization signals (blocks) as needed during the LTM process. This reduces the power consumption of the network side and also helps the UE to quickly obtain synchronization signals (blocks) during the LTM process, thereby reducing LTM latency.

[0515] Example 5: Acquiring synchronization signals (blocks) during the reconstruction process;

[0516] RRC-connected UEs may trigger a rebuild process due to abnormal conditions (such as detecting a radio link failure or handover failure). Afterwards:

[0517] The UE performs cell selection and selects the target cell for reconstruction. Then, the UE can determine the configuration information of the synchronization signal (block) to be transmitted on demand by the target cell based on any of the embodiments 1 to 4.

[0518] Optionally, the UE determines the on-demand synchronization signal (block) being transmitted by the target cell based on the configuration information of the synchronization signal (block) being transmitted on demand by the target cell, and / or the received activation or deactivation synchronization signal (block) command. For example, it determines whether the target cell is transmitting on-demand synchronization signal (block) based on configuration information (such as time domain information, repetition count, duration, activation or deactivation status indication, etc.) or based on the activation or deactivation synchronization signal (block) command.

[0519] During the reconstruction process, the UE can obtain the synchronization signal (block) of the target cell based on the configuration information of the synchronization signal (block) to be sent on demand by the target cell and / or the judgment result of whether it is being sent.

[0520] Through the above process, the UE can quickly obtain the synchronization signal (block) based on the synchronization signal (block) sent on demand by the target cell, thereby reducing the reconstruction delay.

[0521] It should be noted that the relevant content of the above embodiments can be referred to each other, and the repeated parts will not be repeated.

[0522] As described above, the network side can send synchronization signal blocks on demand through the method described above, reducing network side power consumption, while the UE side can also obtain the synchronization signals (blocks) required in the first process in a timely manner, reducing the latency of the first process.

[0659] In this application, the term "cell" can be understood as the coverage area that a node can provide using a carrier. Generally, a "cell" as a radio resource (e.g., time-frequency resource) is associated with bandwidth, which is the frequency range configured for the carrier. The "cell" associated with radio resources is defined by a combination of downlink and uplink resources, such as a combination of DL (Downlink) component carriers (CC) and UL (Uplink) CCs.
