Apparatus and method for transmitting/receiving data in communication system

摘要

An apparatus for transmitting data in a communication system includes: a receiver configured to receive signals from a plurality of terminals in a multiuser-multi-input multi-output (MU-MIMO) scheme; an assignor configured to assign group IDs to terminal groups, respectively after identifying the plurality of terminals and grouping the plurality of terminals into the terminal groups; a generator configured to define a load element which indicates a resource and load state of a basic service set (BSS) through the group IDs and to generate a beacon frame including the load element; and a transmitter configured to transmit the beacon frame to the plurality of terminals in the MU-MIMO scheme.

1. An apparatus for transmitting data in a communication system, the apparatus comprising:
a receiver configured to receive signals from a plurality of terminals in a multiuser-multi-input multi-output (MU-MIMO) scheme; an assignor configured to assign group IDs to terminal groups, respectively, after identifying the plurality of terminals and grouping the plurality of terminals into the terminal groups; a generator configured to define a load element which indicates a resource and load state of a basic service set (BSS) and to generate a beacon frame including the load element; and a transmitter configured to transmit the beacon frame to the plurality of terminals in the MU-MIMO scheme, wherein the receiver measures strengths of the signals received through available frequency bandwidths from the plurality of terminals and calculates use and occupancy levels of each frequency bandwidth of the available frequency bandwidths based on the measured signal strengths, and wherein the load element is defined using any one of the group IDs and the use and occupancy levels.
