Abstract: An apparatus of a communication network detects that a modification of a radio resource control connection for a user equipment is required. The apparatus decides, based on the detected modification requirement, if a re-establishment of a packet data convergence protocol is required for a first radio bearer and/or a second radio bearer, and indicates, in a radio resource control reconfiguration message, the first radio bearer and/or the second radio bearer for which re-establishment of the packet data convergence protocol is required. The user equipment detects, from the radio resource control reconfiguration message, that a modification of a radio resource control connection between the user equipment and the communication network is required, and re-establishes the packet data convergence protocol for the first radio bearer and/or the second radio bearer in accordance with the indication set in the radio resource control reconfiguration message.

Abstract translation: 通信网络的装置检测到需要对用户设备的无线电资源控制连接的修改。 该装置基于检测到的修改要求，决定是否需要对第一无线承载和/或第二无线承载重新建立分组数据会聚协议，并且在无线资源控制重配置消息中指示第一无线承载 无线电承载和/或需要重新建立分组数据会聚协议的第二无线承载。 用户设备从无线资源控制重配置消息中检测出需要修改用户设备和通信网络之间的无线资源控制连接，并且重新建立第一无线承载的分组数据会聚协议和/或 根据在无线资源控制重配置消息中设定的指示的第二无线承载。

Abstract: Amethod includes determining that a full PDCP status report does not fit inot a single PDCP Control PDU, generating a parital PDCP status report that fits into the single PDCP Control PDU, and sending the single PDCP Control PDU containing the partial PDCP status report. Another method includes receiving a PDCP Control PDU where the maximum size thereof is limited, and determining that the received PDCP Control PDU contains a partial PDCP status report instead of a complete PDCP status report. Apparatus, program products, programs, UEs, base stations, and a communication system are also disclosed.
