Opportunistic Uplink Feedback Scheme for MU-MIMO Systems
First Claim
1. A method of using a base station (BS) comprising:
- establishing an association between the base station and at least one mobile station (MS) via a communications channel, wherein the communications channel is divided into resource blocks;
broadcasting a signal-to-noise (SNR) threshold message that includes a SNR threshold;
receiving at least one reporting message, respectively from the at least one mobile station(s), indicating which resource blocks measured a SNR equal to or above the SNR threshold; and
allocating, in a time division multiplexing mode, resource blocks for communication with the mobile station(s) based, at least in part, upon the reporting message(s).

Abstract
According to one general aspect, a method of using a base station comprising establishing an association between the base station and at least one mobile station (MS) via a communications channel. In such an embodiment, the communications channel may be divided into resource blocks. In various embodiments, the method may include broadcasting a signal-to-noise (SNR) threshold message that includes a SNR threshold. In some embodiments, the method may include receiving at least one reporting message, respectively from the at least one mobile station(s), indicating which resource blocks measured a SNR equal to or above the SNR threshold. In various embodiments, the method may also include allocating, in a time division multiplexing mode, resource blocks for communication with the mobile station(s) based, at least in part, upon the reporting message(s).
