Abstract

The present invention provides a method and equipment for multiplexing the media access control layer, which realizes the information indication of PDCP data replication between the network and the terminal, and can ensure that the PDCP PDU and its PDCP data replication are not multiplexed in the same transmission block, thereby ensuring PDCP duplication reliability gain.

Description

technical field [0001] The present invention relates to the technical field of resource allocation, in particular to a method and equipment for multiplexing a Media Access Control (MAC, Media Access Control) layer. Background technique [0002] In order to achieve low latency and high reliability, 5G may introduce Packet Data Convergence Protocol duplication (PDCP, Packet Data Convergence Protocol duplication) function in the carrier aggregation architecture in the future. PDCPduplication, that is, after a certain PDCP protocol data unit (PDU, Protocol Data Unit) is copied, the original PDCP PDU and the copied PDCP PDU are sent through two radio link layer control protocol (RLC, Radio Link Control) entities, such as figure 1 shown. Considering that the reliability gain of two PDCP PDUs in the same transmission block is not obvious, and simultaneous transmission failures are prone to occur, the two PDCP PDUs may be required to be placed in different transmission blocks to en...
