[0026] Before describing the technical proposal of the embodiment of this application, we will first describe the related technology.

[0027] In related technologies, R17 studies inter-cell beam management and supports setting the SSB of a non-serving cell as the beam measurement reference signal, allowing the UE to report the L1-RSRP measurement results of the SSB of the non-serving cell. Figure 1 is a schematic diagram of how a serving cell selects the beam of a non-serving cell to serve the UE in related technologies. In the future R18, a layer 1 / layer 2 (L1 / L2) based cross-cell mobility mechanism will be deployed. That is, delays will be reduced by completing the switching based on L1 / L2 signaling, and synchronous and asynchronous scenarios, intra-frequency (same frequency) and inter-frequency (different frequency) scenarios will be considered.

[0028] Figure 2 is a schematic diagram of the switching process based on Layer 3 signaling in the related technology. As shown in Figure 2, in step 8, after the RAN switching is complete, i.e., the UE achieves synchronization with the target cell and the UE completes the RRC reconfiguration, RRCReconfigurationComplete information is sent to the network side, which indicates that the RRC reconfiguration is complete and the UE can communicate with the target base station.

[0029] In summary, the relevant technology states that the switchover is achieved based on Layer 3 signaling, and after RRC reconfiguration is complete, the UE needs to send an RRC signal (RRCReconfigurationComplete) to the target base station. It does not mention how the switchover is achieved based on Layer 1 or Layer 2 signaling.

[0030] Based on this, embodiments of the present application obtain first information carried by MAC CE or DCI, which is used to indicate at least one of the following: whether to switch to a first cell, whether to activate the RRC settings of the first cell, whether to enable the RRC settings of the first cell, and that the first cell is a candidate target cell.

[0031] Figure 3 is a schematic flowchart of the implementation of an information receiving method according to an embodiment of this application, which is applied to a terminal, and as shown in Figure 3, the information receiving method includes step 301. In step 301, obtain the first information carried by MAC CE or DCI, The first piece of information mentioned above is, Whether or not to switch to the first cell, Whether or not to activate the RRC setting for the first cell. Whether or not to enable the RRC setting for the first cell, and The first cell is used to indicate at least one of the candidate target cells.

[0032] Please understand that the aforementioned candidate target cells may also be called target cells. In other words, the first information is used to indicate to the terminal whether or not to switch to the first cell, or the first information is used to indicate to the terminal whether or not to activate the RRC settings of the first cell and switch to the first cell, or the first information is used to indicate to the terminal whether or not to enable the RRC settings of the first cell and switch to the first cell, or the first information is used to indicate to the terminal whether or not to activate the RRC settings of the first cell, or the first information is used to indicate to the terminal whether or not to enable the RRC settings of the first cell.

[0034] In other words, the cell index is used to indicate the first cell to which the switch should be made, or to indicate the first cell to which the RRC setting should be activated, or to indicate the first cell to which the RRC setting should be enabled.

[0035] Similarly, the setting index is used to indicate the first cell to which the setting should be switched, or the first cell to which the RRC setting should be activated, or the first cell to which the RRC setting should be enabled.

[0036] In one embodiment, when the first information is carried by DCI, the first information corresponds to at least one first field in DCI.

[0037] In other words, when the first information is carried by DCI, the first information may correspond to one first field in DCI, or the first information may correspond to multiple first fields in DCI.

[0038] Furthermore, the field value of the first field can be used to indicate the first cell to switch to, or the first cell where the RRC setting should be activated, or the first cell where the RRC setting should be enabled.

[0039] For example, if the first information corresponds to a first field in DCI, a threshold of 0 for the first field indicates that the identifier of the first cell to switch to or the first cell to activate or enable the RRC setting is cell 0. A threshold of 1 for the first field indicates that the identifier of the first cell to switch to or the first cell to activate or enable the RRC setting is cell 1.

[0047] If the first information indicates to the terminal that it will not switch to the first cell, the terminal responds with an ACK to indicate that it has received the first information and will not switch to the first cell, and responds with a NACK to indicate that it has not received the first information.

[0048] In two cases, if the first information is used to indicate whether or not to activate the RRC setting of the first cell, the second information is used to indicate whether or not the RRC setting of the first cell has been activated.

[0051] In the third case, if the first information is used to indicate whether or not to enable the RRC setting for the first cell, the second information is used to indicate whether or not the RRC setting for the first cell has been enabled.

[0052] If the first piece of information indicates to the terminal that the RRC setting of the first cell should be enabled, the terminal responds with an ACK to indicate that the RRC setting of the first cell has been enabled, and responds with a NACK to indicate that the RRC setting of the first cell has not been enabled or that the terminal has not received the first piece of information.

[0053] If the first information indicates to the terminal that the RRC setting for the first cell will not be enabled, a response from the terminal with an ACK indicates that the first information has been received and the RRC setting for the first cell will not be enabled, while a response with a NACK indicates that the first information has not been received.

[0054] In the four cases, if the first information is used to indicate whether or not to activate the RRC setting of the first cell and switch to the first cell, the second information is used to indicate whether or not to activate the RRC setting of the first cell and switch to the first cell.

[0055] If the first information indicates that the RRC settings of the first cell have been activated and the device has switched to the first cell, a response from the terminal with an ACK indicates that the device has switched to the first cell and activated the RRC settings of the first cell, while a response with a NACK indicates that the device has not switched to the first cell or has not activated the RRC settings of the first cell.

[0056] If the first information indicates that the RRC settings of the first cell will not be activated and the device will not switch to the first cell, a response from the terminal with an ACK indicates that the device has not switched to the first cell and has not activated the RRC settings of the first cell, and a response with a NACK indicates that the device has not received the first information.

[0087] Figure 5 is a schematic flowchart illustrating the specific implementation of the information receiving method and information transmitting method according to the embodiment of this application. Using the first cell as a candidate target cell, the network device as a base station, and the terminal as an UE as an example, the method includes steps 501 to 506, as shown in Figure 5.

[0088] In step 501, the base station where the serving cell (TRP1) is located transmits the RRC settings for the candidate target cell (TRP2) to the UE. In step 502, the base station where the candidate target cell (TRP2) is located transmits a measurement reference signal to the UE. Here, the base station where the serving cell (TRP1) is located and / or the base station where the candidate target cell (TRP2) is located can transmit a measurement reference signal to the UE.

[0089] In step 503, the UE receives the RRC settings and the measurement reference signal, measures the measurement reference signal, and reports the measurement result to the base station where the serving cell (TRP1) is located. In step 504, the base station where the serving cell (TRP1) is located receives the measurement result and transmits Transmission Configuration Indication (TCI) information and / or the first information to the UE. In steps 503-504 above, the measurement performed by the UE refers to the L1 measurement to obtain the L1 measurement result (e.g., the L1-RSRP measurement result).

[0090] The first piece of information mentioned above is, Whether or not to switch to the first cell, Whether or not to activate the RRC settings for the first cell, and This is used to indicate at least one of the following: whether or not to enable the RRC setting for the first cell.

[0091] Here, in order to reduce latency, the aforementioned first information is carried either by MAC CE or by DCI.

[0092] Here, if the first information is carried by MAC-CE, the first information is, Cell index, or Includes configuration index, The cell index or setting index is used to indicate the first cell to switch to, or the first cell to activate the RRC setting, or the first cell to enable the RRC setting.

[0093] Here, if the first information is carried by DCI, the first information corresponds to at least one first field in DCI.

[0094] Here, the threshold of at least one first field in the DCI is used to indicate a first candidate target cell to switch to, or to indicate a first candidate target cell to activate the RRC setting, or to indicate a candidate target cell to enable the RRC setting.

[0095] Here, the DCI further includes at least one second field, the at least one second field being Cell index, or Used to indicate the configuration index, The cell index or setting index is used to indicate the first cell to switch to, or the first cell to activate the RRC setting, or the first cell to enable the RRC setting.

[0096] In step 505, the UE transmits second information to the base station where the serving cell (TRP1) is located.

[0097] Here, TRP1 UE If TCI instruction information is sent only to the UE, the UE will receive the data according to the TCI instruction information.

[0098] Here, if the first information is carried by MAC CE, the second information is transmitted via MAC CE. or If the first information is carried by DCI, then the DCI indicates the resources for transmitting the second information, or The second piece of information is an ACK or NACK to the DCI or a PDSCH scheduled by the DCI.

[0099] In step 506, the base station where the candidate target cell (TRP2) is located transmits data with the UE.

[0100] If the second piece of information indicates that the RRC reconfiguration needs to be updated, the RRC configuration corresponding to the candidate target cell becomes active after X time units. In this way, the base station where the candidate target cell (TRP2) is located transmits data with the UE. The value of X is determined by the UE capability and the interaction time between the serving cell (TRP1) and the candidate target cell (TRP2). If the second piece of information indicates that there is no need to update the RRC configuration, then there is no need to activate the new RRC configuration.

[0101] This example has the following advantages: (1) Switching instructions are given based on Layer 1 (L1) or Layer 2 (L2) signaling, which reduces delays compared to methods that give switching instructions based on Layer 3 signaling in related technologies. Since Layer 3 switching is completed based on Layer 3 measurements and Layer 3 signaling, the measurement time and signaling transmission time are relatively long. On the other hand, since Layer 1 measurements are generally temporary or short-term measurements and the transmission time of Layer 1 or Layer 2 signaling is short, switching based on Layer 1 or Layer 2 can significantly reduce delays. (2) Based on L1 / L2 signaling, the terminal is instructed to switch to a candidate target cell, and if RRC reconfiguration is required or not, the terminal can confirm the first information through the second information.
