Abstract
33When an RRC procedure is combined with an SRNS Relocation procedure, a PDCP synchronization procedure is performed only if a next expected UL/DL Receive PDCP sequence number invalidity event is detected during the SRNS Relocation procedure. If no such invalidity event is detected, then no PDCP sequence number synchronization procedure is performed. If the RRC procedure is not executed in combination with the SRNS Relocation procedure, then the PDCP sequence number synchronization procedure is performed only if: (1) The RRC procedure causes the RLC entity that is used by the PDCP entity to be re-established; or, (2) The RRC procedure causes the header compression protocol used by the PDCP entity to be changed.
