Abstract
Provided is a method and apparatus for selecting a beamformee station (STA) in a multi-user multiple-input and multiple-output (MU-MIMO) communication system, the method including acquiring channel information associated with a beamformee STA among a plurality of beamformee STAs, verifying whether acquiring channel information associated with a subsequent beamformee STA of the beamformee STA is advantageous or disadvantageous, and determining, based on a result of the verifying, whether the channel information associated with the subsequent beamformee STA is acquired.
Claims15
A method of selecting a beamformee station (STA) in a multi-user multiple-input and multiple-output (MU-MIMO) communication system, the method comprising:
- acquiring channel information associated with a beamformee STA among a plurality of beamformee STAs;
- verifying whether acquiring channel information associated with a subsequent beamformee STA of the beamformee STA is advantageous or disadvantageous;
- and
- determining, based on a result of the verifying, whether the channel information associated with the subsequent beamformee STA is acquired,
- wherein the verifying comprises:
- verifying a first transmission rate of a first modulation and coding scheme (MCS) level corresponding to the beamformee STA;
- verifying a second transmission rate of a second MCS level corresponding to the subsequent beamformee STA;
- and
- verifying whether acquiring channel information associated with the subsequent beamformee STA is advantageous or disadvantageous based on the first transmission rate and the second transmission rate.
An apparatus for selecting a beamformee station (STA) in a multi-user multiple-input and multiple-output (MU-MIMO) communication system, the apparatus comprising:
- a channel information acquirer to acquire channel information associated with a beamformee STA among a plurality of beamformee STAs;
- a verifier to verify whether acquiring channel information associated with a subsequent beamformee STA of the beamformee STA is advantageous or disadvantageous;
- and
- a determiner to determine, based on a result of the verifying, whether the channel information associated with the subsequent beamformee STA is acquired,
- wherein the verifier verifies a first transmission rate of a first modulation and coding scheme (MCS) level corresponding to the beamformee STA, verifies a second transmission rate of a second MCS level corresponding to the subsequent beamformee STA is advantageous or disadvantageous based on the first transmission rate and the second transmission rate.
