    摘要: Techniques for controlling transmission of packets on multiple links are described. In one design, a transmitter may generate packets of data for a receiver, assign the packets with sequence numbers from a single sequence number space, demultiplex the packets into multiple streams for multiple links, and send each stream of packets on the associated link to the receiver. The receiver may receive some packets in error, and the correctly received packets may be out of order. In one design, the receiver may maintain the largest sequence number of correctly received packets for each link. After detecting at least one missing packet, the receiver may send status information conveying the missing packet(s) and the largest sequence numbers for all links to the transmitter. The transmitter may use the largest sequence numbers for all links and its packet-to-link mapping to determine whether to quickly resend each missing packet or wait.

    摘要: Systems and methodologies are described that facilitate dynamic load balancing in a communications network. In particular, one or more mobile devices can send random access preambles on an uplink frequency paired to a downlink frequency employed to connect the one or more mobile devices to a base station. The base station can determine if an uplink frequency load imbalance exists based upon the random access preambles. The base station can transmit an indicator on an acquisition indicator channel to at least one mobile device wherein the indicator includes a command to transition to a new uplink frequency. The mobile device can switch uplink frequencies in response to the command.

    摘要: Systems and methods for dynamically adjusting the transmission time interval (TTI) for a communications system are presented. The described aspects provide for dynamically adjusting the TTI in a communication session between a base station or nodeB and a wireless device or user equipment between a shorter TTI, which can provide increased data throughput and lower power consumption, and a longer TTI, which can provide more rugged communication link connections. By dynamically adjusting the TTI, the communications link can be optimized for the given communication channel conditions. Determinations, based on indicia related to the communications system conditions, can be employed in dynamic TTI adjustment. These determinations can be formed centrally at the Radio Network Controller (RNC), at the RNC supplemented with user equipment (UE) available information, or formed in a distributed manner between the RNC and UE across a communications system.

    摘要: Providing for improved wireless communications for user equipment (UE) in a semi-active state is described herein. By way of example, a base station can employ particular wireless channel resources, monitored by a UE in a CELL_FACH state for instance, to trigger channel feedback information from the UE. The trigger can comprise an explicit order instructing the UE to provide data in response, or can include a portion of downlink traffic targeting the UE, where the UE is configured to respond in a suitable manner to receipt of traffic data. The UE can maintain the CELL_FACH state in receiving to and responding to the trigger, and can further receive subsequent traffic data in such state. Accordingly, the subject disclosure provides for improved efficiency and reliability in semi-active state wireless communications.

    摘要: Techniques for scheduling data transmission on multiple carriers in a wireless communication system are described. In one design, a scheduler may receive requested power headrooms for multiple carriers from a user equipment (UE), one requested power headroom for each carrier. Each requested power headroom may be indicative of transmit power usable by the UE for transmission on an associated carrier. The scheduler may also receive queue information indicative of data to transmit by the UE. The scheduler may redistribute the requested power headrooms across the multiple carriers (e.g., based on water filling or greedy filling) to obtain redistributed power headrooms for the multiple carriers. The scheduler may schedule the UE for data transmission on the uplink based on the redistributed power headrooms and the queue information. The scheduler may obtain and send at least one granted power headroom for at least one carrier to the UE.
