FIG. 1 is a schematic diagram of a serving cell in related technologies selecting a beam of a non-serving cell to provide services to a UE. In future R18, a layer 1 / layer 2 (L1 / L2)-based cross-cell mobility mechanism will be developed. That is, by completing the handover based on L1 / L2 signaling, the delay is reduced, and synchronous and asynchronous scenarios, intra-frequency (same frequency) and inter-frequency (different frequency) scenarios are considered.

[0028] FIG. 2 is a schematic diagram of performing handover based on layer 3 signaling in related technologies. As shown in FIG. 2, in step 8, the RAN handover is completed, that is, after the UE realizes synchronization with the target cell and the UE completes the RRC reconfiguration, the UE sends the RRCReconfigurationComplete information to the network side, which indicates that the RRC reconfiguration is completed and the UE can communicate with the target base station.

[0029] In summary, in related technologies, the handover is realized based on layer 3 signaling, and after the RRC reconfiguration is completed, the UE needs to send RRC signaling (RRCReconfigurationComplete) to the target base station. There is no mention of how to realize the handover based on layer 1 or layer 2 signaling.

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

If the threshold of the first field is 1, it indicates that the identifier of the first cell to be switched to or the first cell for which the RRC setting should be activated is cell 1.

[0086] The embodiments of the present application have the following advantages. (1) By performing a handover instruction based on layer 1 (L1) or layer 2 (L2) signaling, compared with the method of performing a handover instruction based on layer 3 signaling in the related art, the delay can be reduced. Since the layer 3 handover is completed based on the measurement quantity of layer 3 and layer 3 signaling, the measurement time and the signaling transmission time are relatively long. On the other hand, since the layer 1 measurement is generally a temporary or short-term measurement and the transmission time of layer 1 or layer 2 signaling is short, the handover based on layer 1 or layer 2 can significantly reduce the delay. (2) Based on L1 / L2 signaling, the terminal is instructed to hand over to a candidate target cell, and the terminal can confirm the first information through the second information, and the confirmation in two cases where it is necessary to reconfigure the RRC and where it is not necessary to reconfigure the RRC is considered.

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

[0088] In step 501, the base station where the serving cell (TRP1) is located transmits the RRC configuration of 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 configuration 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 information (TCI, Transmission Configuration Indication) indication information and / or first information to the UE.

[0090] The first information is Whether to switch to the first cell, Whether to activate the RRC configuration of the first cell, and Whether to enable the RRC configuration of the first cell, and is used to indicate at least one of them.

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

[0092] Here, when the first information is carried by a MAC-CE, the first information is Cell index, or, including a configuration index, wherein the cell index or configuration index is used to indicate a first cell to be switched to or a first cell for which an RRC configuration should be activated or a first cell for which an RRC configuration should be enabled.

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

[0094] Here, a threshold of at least one first field in the DCI is used to indicate a first cell candidate target cell to be switched to or a candidate target cell of a first cell for which an RRC configuration should be activated or a candidate target cell for which an RRC configuration should be enabled.

[0095] Here, the DCI further includes at least one second field, and the at least one second field is a cell index, or, is used to indicate a configuration index, wherein the cell index or configuration index is used to indicate a first cell to be switched to or a first cell for which an RRC configuration should be activated or a first cell for which an RRC configuration should be enabled.

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

[0097] Here, when TRP1 transmits TCI indication information only to the serving cell, the UE receives data according to the TCI indication information.

[0098] Here, when the first information is carried by MAC CE, the second information is transmitted via the MAC CE, or, When the first information is carried by DCI, indicate, via the DCI, a resource for transmitting the second information. Or The second information is an ACK or NACK for the DCI or the PDSCH scheduled by the DCI.

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

[0100] Here, when the second information indicates that it is necessary to update the RRC reconfiguration, after X time units, the RRC configuration corresponding to the candidate target cell becomes effective. By doing so, the base station where the candidate target cell (TRP2) is located performs data transmission 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). Here, when the second information indicates that it is not necessary to update the RRC reconfiguration, there is no need to activate a new RRC configuration.

[0101] This example has the following advantages. (1) By performing a handover instruction based on layer 1 (L1) or layer 2 (L2) signaling, compared with the method of performing a handover instruction based on layer 3 signaling in the related art, the delay can be reduced. Since the layer 3 handover is completed based on the layer 3 measurement quantity and layer 3 signaling, the measurement time and the signaling transmission time are relatively long. On the other hand, since the layer 1 measurement is generally a temporary or short-term measurement and the transmission time of the layer 1 or layer 2 signaling is short, the handover based on layer 1 or layer 2 can significantly reduce the delay.
