摘要： Techniques for transmitting synchronization signals to assist user equipments (UEs) perform cell searches are described. In one design, a base station for a cell may generate and transmit a primary synchronization signal and a secondary synchronization signal, which may be used by the UEs for initial cell search at power up. The base station may also generate and transmit one or more beacon signals, which may be used by the UEs for neighbor cell search to detect for neighbor cells. The number of beacon signals to transmit and the set of subcarriers usable for each beacon signal may be determined based on the system bandwidth. Each beacon signal may be mapped to one subcarrier in the set of subcarriers in each beacon symbol period. This one subcarrier may be determined based on a beacon hopping pattern or a beacon code and may be dependent on a cell identifier (ID).

摘要： Techniques for sending traffic data and control information in a wireless communication system are described. In one design, a transmitter (e.g., a Node B or a UE) may perform beamforming to send traffic data on M layers based on a precoding matrix, where M may be one or greater. The transmitter may also perform beamforming to send control information on up to M layers based on the same precoding matrix used for the traffic data. The transmitter may send the beamformed traffic data on a first physical channel and may send the beamformed control information on a second physical channel. The transmitter may multiplex the beamformed traffic data and the beamformed control information using time division multiplexing (TDM) or frequency division multiplexing (FDM).

摘要： Systems and methodologies are described that facilitate efficient cell acquisition in a wireless communication system. In one aspect, a reference signal for use in cell acquisition can be constructed in a bandwidth-agnostic manner such that it contains a common central portion in a predetermined frequency band that is independent of a bandwidth utilized by an associated wireless communication system. The central portion can be constructed as a two-dimensional block in time and frequency that spans a default cell search bandwidth, a predetermined bandwidth specified by synchronization codes or other signals, or another suitable bandwidth. A reference signal can then be constructed form the central portion by tiling or expanding the central portion such that it spans the entire system bandwidth.

摘要： Techniques for sending multiple-input multiple-output (MIMO) transmissions in wireless communication systems are described. In one design, a transmitter sends a first reference signal via a first link, e.g., a cell-specific reference signal via the downlink. The transmitter receives channel quality indicator (CQI) information determined by a receiver based on the first reference signal. The transmitter also receives a second reference signal from the receiver via a second link, e.g., a sounding reference signal via the uplink. The transmitter obtains at least one MIMO channel matrix for the first link based on the second reference signal. The transmitter determines at least one precoding matrix based on the at least one MIMO channel matrix, e.g., in accordance with ideal eigen-beamforming or pseudo eigen-beamforming. The transmitter then sends a data transmission to the receiver based on the at least one precoding matrix and the CQI information.

摘要： Systems and methodologies are described that provide techniques for efficient cell search in a wireless communication system. In one aspect, a frequency reuse pattern can be generated by applying frequency shifts to reference signals transmitted from cells that provide coverage for a NodeB based on cell IDs or cell group IDs for the cells. The frequency shifts applied to reference signals can then be utilized as a basis for multiplexing reference signals from different cells using frequency division multiplexing (FDM) or a combination of FDM and other multiplexing techniques. Other adjustments to reference signals transmitted from respective cells, such as transmit power adjustments, can further be made to improve detection performance.

摘要： Techniques for sending control information in a wireless communication system are described. In an aspect, a UE spreads control information across frequency with a DFT and across time with an orthogonal sequence to obtain output data for the control information. In one design, the UE receives codewords for N HARQ processes in N downlink subframes, determines an ACK value for each HARQ process, codes N ACK values for the N HARQ processes to obtain ACK information, generates output data for the ACK information, and sends the output data in one of M uplink subframes. In another aspect, first control information is processed based on a first coding and multiplexing scheme utilizing code division multiplexing in time and frequency domains. Second control information is processed based on a second coding and multiplexing scheme utilizing code division multiplexing in time domain and spreading in frequency domain.

摘要： Techniques for sending and receiving acknowledgement (ACK) information in a wireless communication system are described. A base station sends control information and data to a user equipment (UE) and receives ACK information from the UE. The base station performs detection for the ACK information based on (i) a first hypothesis for the control information being missed by the UE and (ii) a second hypothesis for the control information being received correctly by the UE. In one design, the ACK information may have a variable size, and the base station may perform detection for the ACK information based on different block codes for the first and second hypotheses. In another design, the ACK information may have a fixed size, and the base station may perform detection for the ACK information based on a single block code and obtain a fixed number of bits for the ACK information for both hypotheses.

摘要： Techniques for transmitting data using a combination of explicit cyclic delay and implicit cyclic delay are described. A transmitter may perform first processing for cyclic delay diversity (or explicit cyclic delay processing) based on a first set of cyclic delay values known to a receiver. The transmitter may perform precoding based on a precoding matrix either before or after the explicit cyclic delay processing. The transmitter may perform second processing for cyclic delay diversity (or implicit cyclic delay processing) based on a second set of cyclic delay values unknown to the receiver. The transmitter may perform both explicit and implicit cyclic delay processing for data and may perform only implicit cyclic delay processing for pilot. One entity may select the first set of cyclic delay values and inform the other entity. The transmitter may autonomously select the second set of cyclic delay values without informing the receiver.
