1. A terminal device, having a first Packet Data Convergence Protocol (PDCP) entity and a plurality of Radio Link Control (RLC) entities corresponding to the first PDCP entity, and comprising: a processor and a transceiver, wherein
the transceiver is configured to receive first indication information, wherein the first indication information is used for indicating a data behavior between the first PDCP entity and the plurality of RLC entities, wherein the terminal device is capable of making explicit data actions between the PDCP entity and each RLC entity for both carrier aggregation (CA) and dual connectivity (DC) copies; wherein the transceiver is further configured to: receive an Media Access Control (MAC) Control Element (CE) format, wherein the MAC CE format comprises the first indication information;
receive second indication information, wherein the second indication information is used for indicating whether the first indication information is comprised in the MAC CE format,
wherein the transceiver is further configured to:
receive a reserved index in a Logical Channel Identifier (LCID) of a DownLink Shared Channel (DL-SCH) wherein the reserved index is used for indicating whether the first indication information is comprised in the MAC CE format;
wherein the transceiver is further configured to:
receive a second type of MAC CE, the second type of MAC CE is used for indicating a data behavior between an RLC entity and the first PDCP entity corresponding to a second data radio bearer (DRB), wherein the second type of MAC CE is used for indicating a data behavior between the first PDCP entity corresponding to the second DRB and at least three RLC entities.
