摘要： Techniques for signaling power information to facilitate channel quality indicator (CQI) reporting are described. A Node B may send power information that may be used by a UE to determine a power per channelization code, POVSF. In one design, the power information includes a power offset between the power of a data channel, PHSPDSCH, and the power of a pilot channel. The Node B may determine PHSPDSCH based on the power available for the data channel, the number of available channelization codes, and a designated number of channelization codes. The UE may determine POVSF based on the power information from the Node B and the designated number of channelization codes. The UE may estimate at least one SINR of at least one transport block based on POVSF, determine CQI information for the transport block(s) based on the SINR, and send the CQI information to the Node B.

摘要： Techniques for determining and reporting channel quality indicator (CQI) information are described. A user equipment (UE) may determine a transmit power per channelization code, POVSF, based on the available transmit power and a designated number of channelization codes, e.g., by uniformly distributing the available transmit power across all transport blocks and all of the designated number of channelization codes. The UE may estimate SINRs of multiple transport blocks based on POVSF, determine CQI indices for the transport blocks based on the SINRs, and send the CQI indices to a Node B. The Node B may send multiple transport blocks to the UE based on the CQI indices. The Node B may send the transport blocks (i) with the designated number of channelization codes at POVSF or (ii) with a second number of channelization codes at POVSF, with the transport block sizes being scaled based on the designated and second numbers of channelization codes.

摘要： Techniques for sending feedback information in a wireless communication system are described. In one design, precoding control indication (PCI), rank, and channel quality indication (CQI) for data transmission from a transmitter to a receiver may be determined by evaluating different hypotheses. A report may be formed based on the PCI, rank and CQI. The PCI may include a precoding matrix or vector to use for the data transmission. The CQI may include at least one CQI value for at least one transport block to send for the data transmission. The rank and CQI may be combined based on a mapping. For example, the CQI may include one CQI value and fall within a first range of values if one transport block is preferred by the receiver. The CQI may include two CQI values and fall within a second range of values if two transport blocks are preferred.

摘要： Techniques for transmitting data in a manner to support multi-user scheduling, multiple-input multiple-output (MIMO) transmission, and interference cancellation are described. A base station assigns multiple time segments of a transmission time interval (TTI) to at least one terminal, maps data for each terminal to at least one time segment assigned to the terminal, and spreads the data in each time segment with at least one channelization code used in the TTI. A terminal receives an assignment of at least one time segment from among multiple time segments of the TTI, obtains input samples for the at least one time segment, and despreads the input samples with the at least one channelization code used in the TTI.

摘要： Techniques for receiving a MIMO transmission are described. A receiver processes received data for the MIMO transmission based on a front-end filter to obtain filtered data. The receiver further processes the filtered data based on at least one first combiner matrix to obtain detected data for a first frame. The receiver demodulates and decodes this detected data to obtain decoded data for the first frame. The receiver then processes the filtered data based on at least one second combiner matrix and the decoded data for the first frame to cancel interference due to the first frame and obtain detected data for a second frame. The receiver processes this detected data to obtain decoded data for the second frame. The front-end filter processes non on-time signal components in the received data. Each combiner matrix combines on-time signal components in the filtered data to obtain detected data for a channelization code.
