    摘要: A method of receiving a multi-user packet by a receiver in a wireless local area network system. The method includes: receiving a first group identifier (ID) management request message from a transmitter, wherein the group ID management request message includes information about at least one group ID which is intended to be allocated to the receiver for multi user-multiple input multiple output (MU-MIMO) transmission, and the information about the at least one group ID indicates each group ID and a spatial stream set position for the each group ID; transmitting a first group ID management response message to the transmitter, wherein the group ID management response message indicates admission or adjustment for allocation of the at least one group ID; and receiving at least one multi-user packet from the transmitter, wherein the multi-user packet is transmitted using MU-MIMO transmission.

    摘要: A method of transmitting management information, performed by an access point (AP), in a wireless local area network system. The method according to one embodiment includes transmitting, to a station, a frame including a basic service set (BSS) load information element, the BSS load information element including a multi user (MU) multiple input multiple output (MIMO) capable station (STA) count field and a plurality of bandwidth utilization fields. The MU-MIMO capable STA count field indicates a total number of STAB with MU reception capability currently associated with a candidate BSS managed by the AP. Each of the plurality of bandwidth utilization fields includes information about time that each corresponding channel width is busy.
