Patent ID: 8625554

Claim:
For use in a wireless communication network, a mobile station configured to communicate via an uplink transmission to at least one base station in a Multiple Input Multiple Output wireless network, the mobile station comprising: a plurality of transmit antennas; and a transmitter coupled to the plurality of transmit antennas, the transmitter comprising: a layer mapper configured to map data and uplink control information to at least one layer and select a subset of the layers to simultaneously transmit the uplink control information, a plurality of Discrete Fourier Transform (DFT) units configured to perform DFT precoding, wherein the mapping is performed prior to the DFT precoding such that the data and uplink control information are multiplexed and interleaved, a transmit precoding unit configured to perform sub-carrier mapping to outputs of respective ones of the plurality of DFT units, and a plurality of Inverse Fast Fourier Transform (IFFT) units coupled to the transmit precoding unit and respective ones of the plurality of antennas, wherein the transmitter is configured to simultaneously transmit the data and uplink control information on the at least one layer, wherein the uplink transmission comprises at least two component carriers and wherein uplink control information for each of the at least two component carriers is mapped and transmitted separately within the subset of layers.
