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： A base station receiver, a computer program product operable at a base station, and a method operable at a base station receiver, for receiving uplink transmit diversity transmissions utilizing a master/slave scheme at the receiver. One or more tracking loops, such as a searcher task, a time tracking loop, or a frequency tracking loop may be implemented at the base station receiver to determine compensation values, such as finger timings for a rake receiver or frequency compensation values, in accordance with characteristics of a first received pilot channel transmitted utilizing a first precoding weight vector. Here, corresponding compensation values may be derived for the reception of a secondary pilot channel transmitted utilizing an precoding weight vector orthogonal to the first precoding weight vector, simply based on those determined for the first pilot channel.
