摘要： Briefly, in accordance with one or more embodiments, a communication link is established between a base station and a mobile station. The base station transmits a feedback allocation to the mobile station for the allocation of the resources of a feedback channel. If the feedback allocation is to be terminated, the base station transmits a feedback deallocation to the mobile station. If the feedback deallocation is successful, the mobile station transmits a deallocation confirmation to the base station to confirm receipt of the feedback deallocation.

摘要： A method providing channel quality indicator (CQI) feedback from subscriber stations (SSs) to a base station (BS) may include a combination of a thresholding scheme and a best-M scheme. Another method providing CQI feedback may include providing multiple feedback channels, with SSs randomly allocating CQI values among the multiple feedback channels. The BS may choose a prevailing CQI message when channel contention occurs. Another method of providing CQI feedback may include SSs transmitting to the BS numbers of their CQI values that exceed a CQI threshold. Based on these numbers, the BS may determine how many CQI values each SS may send, and on which channels. The SSs may send these CQI values according to instructions from the BS.

摘要： A beam selection method in open loop MU-MIMO is disclosed, for an asymmetric antenna configuration. The proposed beam selection method employs limited feedback, as compared with single-user closed-loop MIMO and multiple-user closed-loop MIMO, in which the base station requires channel state information (CSI). The multi-user MIMO beam selection method selects the portion of beams from candidate beams for data transmission, meaning that the base station is training M beams. From this, the subscriber station selects N beams from the total M beams, with N≦M.

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.
