    摘要： Techniques for monitoring grant channels in a wireless communication network are described. In one design, a user equipment (UE) determines whether a monitoring condition is satisfied, monitors at least one grant channel for grants of radio resources if the monitoring condition is satisfied, and stops monitoring the at least one grant channel if the monitoring condition is not satisfied. The UE may determine that the monitoring condition is satisfied after sending scheduling information indicating that there is data to send, if there is an outstanding grant of radio resources, if a grant of radio resources is expected, if there is at least one scheduled flow and a data buffer for the scheduled flow(s) is not empty, if there is an outstanding grant of radio resources and data transmission has been sent using this grant of radio resources, if there is at least one other control channel to monitor, etc.

    摘要： Methods and apparatuses for facilitating switching HSPA (high speed packet access) serving cells from each of an RNC (radio network controller), base station, and access terminal are provided. The RNC pre-configures an access terminal and each base station in an active set for HS-DSCH operation by providing identification codes identifying each of the base stations. The RNC transmits data packets tagged with sequence numbers to each base station where they are synchronously buffered. The access terminal initiates a handover by transmitting a PDU (protocol data unit) to each of the base stations. The PDU is encoded with the identification code of a target base station and a sequence number of a subsequent packet. The target receives the PDU and directly completes the handover with the access terminal.

    摘要： Systems and methods are provided for a signaling an ongoing communication of a data unit in a data packet is to be aborted. Upon a determination to abort an ongoing communication is made, a code-point in a data unit header is utilized to indicate the ongoing communication is to be aborted. A first class of code-point is a dedicated, predefined abort data unit field header. A second class of code-point is a combination of a set of existing, predefined data unit header fields, at least one data unit header field in the combination holds a value that is either invalid or legitimate yet unlikely to occur. Conveying code-point(s) to indicate termination of an ongoing communication of a data unit in a data packet in a regular communication mitigates transmission disruption and saves channel capacity.

    摘要： A method, an apparatus, and a computer program product for wireless communication are provided to enable a reduction in processing power while handling high data rates. An apparatus includes a processing system configured to service a MAC PDU. Here, the MAC PDU includes a MAC header and at least one MAC SDU. The MAC header includes a transmission sequence number (TSN) having a length greater than 6 bits. Further, the processing system is configured to read the MAC header and to transport the MAC PDU in accordance with the MAC header between a MAC and a PHY utilizing one or more transport blocks over one or more transport channels.

    摘要： A data packet communication system employs radio link control (RLC) transmission between a transmitter and a receiver with an Automatic Repeat Request (ARQ) arrangement whereby polling of the receiver is accomplished with reduced amount of redundantly transmitted data, such as between an access node and terminal. Upon a polling event, such as emptying of a transmission buffer of the transmitter, expiration of a polling timer, or reaching a radio link control (RLC) protocol data units (PDUs) count threshold, the transmitter sends a polling command to the receiver. This polling command is smaller than any of the RLC PDUs, which are conventionally resent with a polling bit set to evoke a STATUS PDU from the receiver. With evolving communication standards tending toward larger PDUs, such as in excess of a kilobyte for HSPA+ (High-Speed Packet Access Evolution) and 3GPP LTE (Long Term Evolution), this inefficiency can be of increasing impact.
