Title:
COMMUNICATION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/013127
Kind Code:
A1
Abstract:
Provided are a communication method and a communication apparatus. The method comprises: a first apparatus establishing a first radio link control (RLC) entity and a second RLC entity, wherein the first RLC entity and the second RLC entity are associated with a first packet data convergence protocol (PDCP) entity; and the first apparatus sending first data by means of the first RLC entity and/or the second RLC entity. The first RLC entity corresponds to a unicast transmission mode, and the second RLC entity corresponds to a multicast transmission mode. According to the communication method provided in the present application, one PDCP is configured such that an RLC entity corresponding to a unicast transmission mode is associated with an RLC entity corresponding to a multicast transmission mode. Date transmission is carried out by means of an RLC entity corresponding to a unicast transmission mode and/or an RLC entity corresponding to a multicast transmission mode, thereby realizing flexible switching between the unicast transmission mode and the multicast transmission mode, reducing the signaling overhead and time delay of switching transmission modes, and improving the reliability of data transmission.
