    摘要： Methods and apparatuses for reducing an amount of bandwidth required for feedback to a transmitter station in a closed-loop multiple-input multiple-output (MIMO) system are described herein. The methods may include initially measuring at a receiver station channel qualities associated with receiving signals from a transmitter station for a first and a second spatial channel, the transmitter and receiver stations employing a closed-loop MIMO system. The receiver station may then determine a first and a second channel quality indicator (CQI) based on the measured channel qualities and may then transmit to the transmitter station the first and the second CQI to directly and indirectly identify a first and a second modulation coding scheme (MCS) entry among a plurality of ordered MCS entries, respectively. The second MCS entry being one of a selected subset of lower ordered MCS entries relative to the first MCS entry. The transmitter station may selectively use the first and the second identified MCS to transmit signals to the receiver station over the first and the second spatial channel, respectively.

    摘要： Embodiments of a base station and method for resource allocation using localized and distributed resource blocks are generally described herein. The base station comprises processing circuitry to allocate localized resources to user stations based on receipt of channel quality information received from the user stations and to allocate distributed resource to user stations based on non-receipt of channel quality information. The base station also comprises physical layer circuitry to transmit control information on a physical channel to indicate the resources that are allocated to each scheduled user station.

    摘要： Methods and apparatuses for providing CQI feedback to a transmitter station are described herein. In one implementation, an apparatus may include a transceiver to transmit and receive signals to and from a transmitter station, and a controller coupled to the transceiver to control the transceiver to transmit to the transmitter station a first channel quality indicator (CQI) that corresponds to a first modulation level to be used by the transmitter station to transmit first signals, and to control the transceiver to transmit to the transmitter station a differential indicator that comprises two bits or less to differentially indicate a second CQI relative to the first CQI, wherein the second CQI corresponds to a second modulation level to be used by the transmitter station to transmit second signals. Other embodiments may be described and/or claimed.
