Abstract

The invention provides a receiving method, a sending method and communication equipment, and the method comprises the steps: obtaining a repeatability detection parameter; and utilizing the repeatability detection parameters to carry out repeatability detection on the received auxiliary link packet data convergence protocol data unit. According to the scheme provided by the invention, when the receiving end receives the packet data convergence protocol data unit generated based on the replication of the sidelink data, the repeatability detection is carried out by utilizing the determined repeatability detection parameters, so that the repeatability detection of the packet data convergence protocol data unit based on the sidelink data is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of secondary link data replication, in particular, a receiving method, a sending method and a communication device capable of performing repeatability detection of secondary link data. Background technique [0002] Currently, R15V2X communication introduces sidelink packet duplication (Sidelink Packet Duplication) to improve the reliability of sidelink V2X message transmission. Among them, the secondary link terminal performs a data replication function at the PDCP (Packet Data Convergence Protocol) layer, and the copied secondary link PDCP PDU (Protocol Data Unit, protocol data unit) is respectively submitted to two different RLCs ( Radio Link Control, wireless link control) entity. Different RLC entities correspond to different logical channels, and different logical channels have different LCIDs (Logical Channel Identify, logical channel identification). In addition, since the ...
