  • Publication number: 20200177312
    Abstract: A method and apparatus for implementing spatial processing with unequal modulation and coding schemes (MCSs) or stream-dependent MCSs are disclosed. Input data may be parsed into a plurality of data streams, and spatial processing is performed on the data streams to generate a plurality of spatial streams. An MCS for each data stream is selected independently. The spatial streams are transmitted via multiple transmit antennas. At least one of the techniques of space time block coding (STBC), space frequency block coding (SFBC), quasi-orthogonal Alamouti coding, time reversed space time block coding, linear spatial processing and cyclic delay diversity (CDD) may be performed on the data/spatial streams. An antennal mapping matrix may then be applied to the spatial streams. The spatial streams are transmitted via multiple transmit antennas. The MCS for each data stream may be determined based on a signal-to-noise ratio of each spatial stream associated with the data stream.

  • Patent number: 9571175
    Abstract: A method and apparatus for encoding channel quality indicator (CQI) and precoding control information (PCI) bits are disclosed. Each of the input bits, such as CQI bits and/or PCI bits, has a particular significance. The input bits are encoded with a linear block coding. The input bits are provided with an unequal error protection based on the significance of each input bit. The input bits may be duplicated based on the significance of each input bit and equal protection coding may be performed. A generator matrix for the encoding may be generated by elementary operation of conventional basis sequences to provide more protection to a most significant bit (MSB).

  • Publication number: 20150100863
    Abstract: A method and apparatus for encoding and decoding a data block are disclosed. The data block may be for a physical channel. Further, the data block may be for a shared channel. For data block encoding, a Node-B may calculate cyclic redundancy check (CRC) bits for the data block. The data block may be used to calculate the CRC bits. The Node-B may mask the CRC bits with a wireless transmit/receive unit (WTRU) identity (ID). Further, the Node-B may attached the masked CRC bits to the data block. Using a transmitter, the Node-B may transmit the data block over a physical channel. Further, the Node-B may transmit the data block over a shared channel. A WTRU may receive the data block, including the masked CRC bits. Using the WTRU ID, the WTRU may de-mask the CRC bits. The WTRU may perform a CRC check using the de-masked CRC bits.

  • Patent number: 8019036
    Abstract: In an orthogonal frequency division multiplexed (OFDM) multiple-in multiple-out (MIMO) wireless communication system, a method for correcting sampler clock frequency offset in a receiver comprises acquiring the frequency offset and symbol timing in a received signal by the receiver. The estimated value of a fractional offset is computed, and a correction in the frequency domain based upon the estimated value of the fractional offset is performed.
