    摘要: The transmission and decoding of resource blocks (RBs) transmitted via a multiple-input multiple-output (MIMO) antenna having a plurality of transmit antennas is disclosed. Each RB includes a plurality of resource elements (REs). Each RE is reserved for one of a common reference signal (CRS) associated with one of the transmit antennas, a dedicated reference signal (DRS) including a single beamformed or precoded pilot, a DRS including a composite beamformed or precoded pilot, and a data symbol. Each RB may include a “control type” data symbol that indicates a DRS mode associated with the RB. In one DRS mode, each DRS includes a single beamformed or precoded pilot. In another DRS mode, each DRS includes a composite beamformed or precoded pilot. In yet another DRS mode, single beamformed or precoded pilots, and composite beamformed or precoded pilots, may coexist and be transmitted simultaneously within the same RBs or in different RBs.

    摘要: A method for transmitting feedback information for a wireless transmit receive unit (WTRU) includes multiplexing the feedback information with an uplink shared channel, mapping the multiplexed feedback information to orthogonal frequency division multiplex (OFDM) symbols and transmitting the feedback information to an e Node B. The method also includes multiplexing the feedback information with the uplink shared channel using distributed frequency division multiplexing (FDM), mapping the feedback information to a first OFDM symbol, and distributing the mapped feedback information equidistantly across the transmission bandwidth.

    摘要: A method and apparatus for channel coding and rate matching of the Physical Uplink Control Channel (PUCCH) and the Physical Downlink Control Channel (PDCCH) is disclosed that uses convolutional encoding to code the control channels. Rate matching is performed using a circular buffer based rate matching algorithm. A rate matching module may contain a single interleaver or may alternatively comprise a plurality of sub-block interleavers. Interleaved coded bits may be stored in the circular buffer in an interlaced format, or output streams from separate sub-block interleavers may be stored contiguously. When a plurality of sub-block interleavers are used, different interleaving patterns may be used. Rate matching may use bit puncturing or repetition to match the rate of the available physical channel resource. Rate matched output bits may be interleaved using a channel interleaver.

    摘要: A method of generating an index value associated with a primary synchronization code within a communication signal includes splitting a sampled communication signal into even and odd samples. The even and odd samples are correlated with a primary synchronization code of the communication signal and complex values of the even and odd samples are generated. Signal strength values for the even and odd samples are approximated and the approximate signal strength values within a frame of the communication signal are accumulated. A highest accumulated signal strength value is assigned as an index value.
