PROTOCOL DATA UNIT SEQUENCE NUMBER SYNCHRONIZATION IN WIRELESS COMMUNICATIONS

Abstract

Methods, systems, and devices for wireless communications are described in which one or more network entities may transmit protocol data units (PDUs) that may include a set of bits that indicate a packet data convergence protocol (PDCP) window at a receiving user equipment (UE) may be reset. The set of bits may have a first value that indicates the PDCP window is to be set with a lower bound, or left edge, that corresponds to a sequence number (SNs) indicated in the PDU. The UE may thus reset the PDCP window and buffer the received PDU for a radio bearer, without waiting for SNs to be within a prior PDCP window. The set of bits may have a second value that indicates the PDCP window is to be reset after a configured time period.
