摘要： A digital communications system for delivering data blocks includes at least one transmit/receive unit (TRU). The TRU includes a storage element for receiving transmit data packets and retransmit data packets from a sending unit and a processing element communicatively coupled to the storage element. The processing element is configured for recognizing a failure to receive at least one other transmit data packet (missing data packet) from the sending unit, and for configuring a status control packet for transmission to the sending unit, the control packet includes a header including a next packet identifier for a next data packet anticipated to be received and a status payload portion including a missing packet identifier including the transmit packet identifier for the missing data packet. In the system, the retransmit data packet includes at least a segment of the data payload in the missing data packet associated with the missing packet identifier.

摘要： Embodiments of the invention provide a method to efficiently enable Network MIMO for use in the downlink direction. An association is established between a primary NodeB in a first cell and a secondary NodeB in an adjacent second cell. A set of downlink transmission resources is reserved for use by both the primary NodeB and the secondary NodeB. A transport block is transmitted from the secondary NodeB simultaneously with the primary NodeB to a user equipment (UE) near the edge of the first cell in response to a schedule provided by the primary NodeB. A time instance of the reserved transmission resources is released by the secondary NodeB when no simultaneous transmission of a transport block is scheduled within a minimum time.

摘要： This invention employs an inherent tradeoff in a radio bearer dependent data handling method for intra-E-UTRA handoffs. For user equipment using real time data, the source node forwards to the target node not yet acknowledged real time service data units and disconnects. This makes the handoff latency short at the expense of data traffic between nodes. For user equipment not needing real time data, the source node continues to receive user equipment acknowledgements during a time out period and only forwards service data units acknowledged during the time out period. This reduces X2 interface traffic between the source and target nodes but extends the handoff latency.

摘要： A system for communicating protocol layer processing information is disclosed herein. A transmitter includes a protocol layer header generator that generators a header for a first protocol data unit. The header generator provides a first header comprising a first sequence number field that determines the order in which a receiving entity present the first data unit to higher protocol layer. The sequence number field varies in length. A receiver includes a protocol layer header parser that parses a header of a first protocol data unit. The header parser parses a first header comprising a first sequence number field that determines the order in which the first data unit is presented to a higher protocol layer. The sequence number field varies in length.
