Abstract: Systems and methodologies are described herein that facilitate efficient handling of packets (e.g., Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) or Service Data Units (SDUs)) in a wireless communication system. As described herein, a number of consecutive packets that are discarded due to a discard timer expiration event and/or other causes can be monitored and compared to a number of tolerated consecutive discarded packets. If the number of consecutive discarded packets does not exceed the number of tolerated consecutive packets, conventional processing operations such as header modification and compression, ciphering, or the like can be omitted for respective packets subsequent to a discarded packet, thereby significantly reducing processing overhead. As further described herein, the number of tolerated consecutive discarded packets can be chosen to maintain header compression (e.g., Robust Header Compression (RoHC)) synchronization, ciphering synchronization, and/or other suitable properties.

Abstract: This innovation relates to systems and methods for transmission of protocol data units, and more particularly to processing polling requests from a radio link control peer. A radio link control transmitter can poll a receiver to obtain a report re-garding the status of a set of data packets, and the polls can be sent in-band with a data packet. The receiver can determine to wait before sending the status report based on one or more characteristics of the received data packets.

Abstract: Se describen sistemas y metodologías que facilitan la formación y/o despacho de reportes de estado de protocolo de control de enlace de radio (RLC) a una estación base. El sistema puede incluir componentes que cuantifican una ausencia de unidades de datos de protocolo, aseguran si un número de unidades de datos de protocolo faltantes excede el tamaño de una concesión del lado de transmisión, insertar un número de secuencia asociado con una primera unidad de datos de protocolo faltante en un campo de números de secuencia de confirmación asociado con un reporte de estado parcial, incorpora el número de secuencia asociado con la primera unidad de datos de protocolo faltante en el reporte de estado parcial, incluye números de secuencia de unidades de datos de protocolo faltantes subsiguientes en el reporte de estado parcial sin exceder la concesión del lado de transmisión y envía el reporte de estado parcial a la estación base.

Abstract: Systems and methodologies are described that facilitate formation and/or dispatch of radio link control (RLC) protocol status reports to a base station. The system can include components that quantify an absence of protocol data units, ascertain whether a number of absent protocol data units exceeds the size of a transmission side grant, insert a sequence number associated with a first absent protocol data unit into an acknowledgement sequence number field associated with a partial status report, incorporates the sequence number associated with the first absent protocol data unit in the partial status report, includes sequence numbers of subsequent absent protocol data units into the partial status report without exceeding the transmission side grant, and sends the partial status report to the base station.
