Patent ID: 8755452

Claim:
A wireless communication station for communicating with mobile devices in a cellular network using multiple-access technique, the station comprising: a receiver to receive indicators from a mobile device including an indicator of channel state; an encoder to encode a data stream into an encoded data stream at least based in part on the indicator of channel state; one or more mappers to map the encoded stream onto an orthogonal frequency division multiplexing (OFDM) subcarrier symbol stream based at least in part on the indicator of channel state, the indicator of channel state comprising an indicator of channel state for each group of OFDM subcarriers; a coding mode selector to receive the OFDM subcarrier symbol stream and to configure a coding mode for transmission of non-control information on a shared channel in accordance with both a diversity mode and a non-diversity mode, the non-diversity mode including a spatial multiplexing mode; and a transmitter to transmit a control channel, separate from the shared channel, the control channel including control information to the mobile device that indicates at least the selected transmission mode of a plurality of transmission modes used for the transmission of the non-control information on the shared channel, wherein the coding mode selector is arranged to select both transmission modes for groups of OFDM subcarriers and is configurable to switch between the transmission modes to allow the transmitter to transmit some symbols of a group of OFDM subcarriers in accordance with the diversity mode and configurable to transmit some other symbols of the group of OFDM subcarriers in accordance with the non-diversity mode.
