    摘要： Specifically, a method and system that performs MIMO and beamforming at a base station based on an uplink channel sounding (ULCS) from only one of the mobile station antennas and closed-loop multiple input, multiple output (MIMO) schemes based on the singular value decomposition (SVD) of the channel matrix. The ULCS is limited to sounding and the channel uses fewer than an optimal number of transmit antennas (e.g. one for WiMAX). The base station arrays may be configured for a full array transmitting mode or a sub-array transmitting mode.

    摘要： A wireless communications system base station (101), upon receiving (202) from a mobile station (102) a wireless transmission that comprises a suggested transmitter-receiver configuration, can respond (in appropriate instances) by automatically transmitting (203) to the mobile station a wireless transmission comprising an indication to use instead a default transmitter-receiver configuration. By one approach, the latter action can be based, at least in part, upon a determination regarding reliability (301) of that suggested transmitter-receiver configuration (which might comprise, for example, a direct or indirect measure of quality of the channel by the default transmitter-receiver configuration was received) to provide a corresponding reliability assessment. The latter can then be used (302) to determine whether to use this suggested transmitter-receiver configuration for a subsequent communication with the mobile station.

    摘要： A user equipment (UE) receives a signal comprising multiple resource blocks and configured for receiving a subframe comprising multiple time-frequency resources, the time-frequency resources comprising at least two control channel candidates. The UE determines a first control channel candidate of the at least two control channel candidates in the subframe, determines a first antenna port (AP) associated with the first control channel candidate, decodes the first control channel candidate based on the first AP, determines a second control channel candidate of the at least two control channel candidates in the subframe, determines a second AP associated with the second control channel candidate, and decodes the second control channel candidate based on the second AP, wherein the AP used for decoding the first control channel candidate is distinct from the AP used for decoding the second control channel candidate.

    摘要： A technique for determining a received signal strength indicator of a target base station at a subscriber station includes performing a discrete Fourier transform on a received signal to provide a transformed signal. In this case, the transformed signal occupies one or more segments of a channel and the one or more segments each include multiple subcarriers. A shift-n cross-correlation is calculated based on the transformed signal and a preamble sequence of the target base station to provide a coarse received signal strength indicator for the target base station.
