STAGED MULTI-USER GROUPING FOR MULTIPLE-INPUT, MULTIPLE-OUTPUT WIRELESS COMMUNICATIONS

摘要

A method of performing MIMO wireless communication includes identifying a first wireless device that qualifies for inclusion in a multi-user (MU) group and identifying a set of one or more candidate wireless devices, distinct from the first wireless device, that qualify for inclusion in the MU group. The set includes a second wireless device. A determination is made that an estimated MU-mode net goodput for the first and second wireless devices is greater than an estimated average single-user-mode net goodput for the first and second wireless devices. The first and second wireless devices are included in the MU group based at least in part on the determination. A transmission is sent to the MU group. Net goodput corresponds to a number of bits that may be successfully transmitted divided by a sum of a time to transmit the number of bits and a time associated with network overhead.

1. A method of performing multiple-input, multiple-output (MIMO) wireless communication, comprising:
identifying a first wireless device that qualifies for inclusion in a multi-user (MU) group; identifying a set of one or more candidate wireless devices, distinct from the first wireless device, that qualify for inclusion in the MU group, wherein the set includes a second wireless device; making a first determination that an estimated MU-mode net goodput for the first and second wireless devices is greater than an estimated average single-user-mode net goodput for the first and second wireless devices, wherein net goodput corresponds to a number of bits that may be successfully transmitted divided by a sum of a time to transmit the number of bits and a time associated with network overhead; including the first and second wireless devices in the MU group based at least in part on the first determination; and sending a transmission to the MU group.
