HETEROGENEOUS MULTI-USER GROUPS FOR WIRELESS COMMUNICATIONS

摘要

Methods, systems, and devices are described for wireless communications. An access point (AP) communicates to a multi-user (MU) group of stations (STAs) that are assigned disparate modulation and coding schemes (MCSs). The AP sends an MU transmission to the MU group using an MCS and transmit power combination that is associated with the highest estimated throughput. The AP selects the MCS and transmit power combination from two configurations. In the first configuration, a single MCS and corresponding transmit power is used for the MU transmission. In the second configuration, a single transmit power and two different MCSs are used for the MU transmission. Both configurations may use the MCSs associated with the STAs in the MU group. The transmit power may correspond to one of the selected MCSs.

1. A method for wireless communication, comprising:
forming a multi-user (MU) group comprising a primary station associated with a first modulation and coding scheme (MCS) and a secondary station associated with a second MCS, wherein the second MCS is different from the first MCS; estimating a throughput for at least one MU transmission configuration from the group consisting of:
a first MU transmission configuration using a common MCS for the primary station and the secondary station at a transmit power corresponding to the common MCS, wherein the common MCS is selected from the group consisting of the first MCS and the second MCS; anda second MU transmission configuration using the first MCS for the primary station and the second MCS for the secondary station, wherein the primary station and the secondary station use a transmit power corresponding to the second MCS; and transmitting to the MU group according to one of the MU transmission configurations based at least in part on the estimated throughput for the MU transmission configurations.
