  • Publication number: 20130329626
    Abstract: 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.
