Retransmission activating/deactivating method, base station, user equipment and device

A duplication activating/deactivating method, applied to a user equipment (UE) in communication with multiple base stations, comprising:

• determining a correspondence relationship between a bearer which is allowed for duplication under a first base station and a bit of a preset field of media access control (MAC) control element (CE) of the first base station for activating/deactivating duplication;
• wherein the preset field is used to indicate activation/deactivation duplication of the bearer which is allowed for duplication;
• and
• when receiving the MAC CE for activating/deactivating duplication transmitted from the first base station, according to the correspondence relationship, parsing the bit, which is in the preset field of the MAC CE of the first base station for activating/deactivating duplication and corresponding to the bearer which is allowed for duplication under the first base station;
• according to indication of the bit, determining activation/deactivation duplication of the corresponding bearer;
• wherein the method further includes:
• (i) the preset field of the MAC CE from the first base station for activating/deactivating duplication, and a preset field of MAC CE from another base station in communication with the UE for activating/deactivating duplication, have mutually independent structures;
• bits in the preset field of the MAC CE from the first base station for activating/deactivating duplication, have correspondence relationship with bearers which are allowed for duplication under the first base station;
• bits in the preset field of the MAC CE from another base station for activating/deactivating duplication, have correspondence relationship with bearers which are allowed for duplication under the another base station;
• or,
• (ii) the preset field of the MAC CE from the first base station for activating/deactivating duplication, and a preset field of MAC CE from another base station in communication with the UE for activating/deactivating duplication, have mutually independent structures;
• bits in the preset field of the MAC CE from the first base station for activating/deactivating duplication, have correspondence relationship with bearers which are allowed for duplication only under the first base station;
• and bits in the preset field of the MAC CE from the first base station for activating/deactivating duplication, have correspondence relationship with special bearers which are allowed for duplication under the first base station;
• wherein the special bearers are retransmitted in a dual-connectivity manner or multi-connectivity mode, and a master base station for the special bearers is the first base station.

A user equipment (UE), comprising:

• a transceiver, a memory, a processor, and a computer program stored on the memory and executable on the processor;
• wherein the processor is used to read the program in the memory and perform the following procedures:
• determining a correspondence relationship between a bearer which is allowed for duplication under a first base station and a bit of a preset field of media access control (MAC) control element (CE) of the first base station for activating/deactivating duplication;
• wherein the preset field is used to indicate activation/deactivation duplication of the bearer which is allowed for duplication;
• the transceiver is used to receive the MAC CE for activating/deactivating duplication transmitted from the first base station;
• wherein the processor is further used to perform the following procedures:
• according to the correspondence relationship, parsing the bit, which is in the preset field of MAC CE of the first base station for activating/deactivating duplication and corresponding to the bearer which is allowed for duplication under the first base station;
• and,
• according to indication of the bit, determining activation/deactivation duplication of the corresponding bearer;
• wherein the user equipment further includes:
• (i) the preset field of the MAC CE from the first base station for activating/deactivating duplication, and a preset field of MAC CE from another base station in communication with the UE for activating/deactivating duplication, have mutually independent structures;
• bits in the preset field of the MAC CE from the first base station for activating/deactivating duplication, have correspondence relationship with bearers which are allowed for duplication under the first base station;
• bits in the preset field of the MAC CE from another base station for activating/deactivating duplication, have correspondence relationship with bearers which are allowed for duplication under the another base station;
• or,
• (ii) the preset field of the MAC CE from the first base station for activating/deactivating duplication, and a preset field of MAC CE from another base station in communication with the UE for activating/deactivating duplication, have mutually independent structures;
• bits in the preset field of the MAC CE from the first base station for activating/deactivating duplication, have correspondence relationship with bearers which are allowed for duplication only under the first base station;
• and bits in the preset field of the MAC CE from the first base station for activating/deactivating duplication, have correspondence relationship with special bearers which are allowed for duplication under the first base station;
• wherein the special bearers are retransmitted in a dual-connectivity manner or multi-connectivity mode, and a master base station for the special bearers is the first base station.
