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： In a wireless communication system in which a user using a mobile equipment requests a serving cell handoff from a source cell to a target cell, the mobile equipment monitors authorization for the handoff from the target cell. At the same time, the mobile equipment can decode data from either the source cell or the target cell. Upon receipt of authorization for the handoff, the mobile equipment sends confirmation of the handoff to the target cell.

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： Techniques for reporting acknowledgement (ACK) information and channel quality indication (CQI) information in a wireless communication system are described. A user equipment (UE) may be able to receive data from up to two cells with dual-cell operation. The UE may determine CQI information for a first cell, determine CQI information for a second cell, and send the CQI information for both cells on a feedback channel with a single channelization code. The UE may process a control channel from each cell and, if control information is received from the cell, may further process a data channel from the cell to receive data sent to the UE. The UE may determine ACK information for each cell based on processing results for the data and control channels from that cell. The UE may send the ACK information for both cells on the feedback channel with the single channelization code.

摘要： Synchronization of uplink carriers for transmission is disclosed in accordance with different aspects. The uplink carriers that transmit information are configured such that at least one of the uplink carriers is an anchor carrier. When a plurality of carriers are thus configured for the uplink, they are synchronized such that they bear a predetermined phase relationship with each other. The predetermined phase relationship between the plurality of carriers depends on the transmit timing of the anchor carrier or a combination of transmit timings of the anchor carrier and one or more non-anchor carriers comprised within the uplink carriers.

摘要： Techniques for managing operation of a user equipment (UE) in a multi-carrier system are described. The system may support two or more carriers on the downlink and one or more carriers on the uplink. One carrier on each link may be designated as an anchor carrier. In an aspect, a lower layer order (e.g., an HS-SCCH order) may be used to transition the UE between single-carrier and multi-carrier operation. In another aspect, the UE may have the same discontinuous reception (DRX) configuration for all downlink carriers and/or the same discontinuous transmission (DTX) configuration for all uplink carriers. In yet another aspect, HS-SCCH-less operation may be restricted to the anchor carrier.

摘要翻译： 描述了用于管理多载波系统中的用户设备（UE）的操作的技术。 系统可以支持下行链路上的两个或更多个载波，以及上行链路上的一个或多个载波。 每个链路上的一个载波可以被指定为锚定载波。 在一个方面，可以使用较低层次（例如，HS-SCCH顺序）来在单载波和多载波操作之间转换UE。 在另一方面，对于所有上行链路载波，UE可以对于所有下行链路载波和/或相同的不连续传输（DTX）配置具有相同的不连续接收（DRX）配置。 在另一方面，可以将HS-SCCH-less操作限于锚定载体。
