一种配置PDCP实体的方法、接收装置和发送装置制造方法及图纸

本申请公开了一种配置分组数据汇聚协议(PDCP)实体的方法、接收装置和发送装置，该方法包括：接收端接收第一发送端发送的序列号(SN)指示信息，SN指示信息用于指示第一发送端使用第一SN长度向接收端发送的最后一个数据协议单元(PDU)的SN；接收端在接收到携带SN的PDU时，对接收端的PDCP实体进行重配置，以使得接收端能够通过重配置的PDCP实体，接收第一发送端使用第二SN长度发送的PDU或第二发送端使用第二SN长度发送的PDU。由于接收端在接收到发送端使用第一SN长度发送的最后一个PDU时，才对接收端的PDCP实体进行重配置，避免了PDCP实体重配置过程中的丢包。

A Method, Receiving Device and Transmitting Device for Configuring PDCP Entities

This application discloses a method, a receiving device and a transmitting device for configuring the entity of the packet data aggregation protocol (PDCP). The method includes: the receiving end receives the sequence number (SN) indication information sent by the first sender, and the SN indication information is used to indicate the SN of the last data protocol unit (PDU) sent by the first sender to the receiving end using the first SN length; and the receiving end receives the SN carried by the receiving end. In PDU, the PDCP entity of the receiving end is reconfigured so that the receiving end can receive the PDU sent by the first sender using the second SN length or the PDU sent by the second sender using the second SN length through the reconfigured PDCP entity. Since the receiving end reconfigures the PDCP entity of the receiving end only when it receives the last PDU sent by the sender using the first SN length, it avoids the packet loss during the reconfiguration of the PDCP entity.
