    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.

    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.
