Abstract
A method and apparatus of transmitting in a wireless communication system is provided. A transmitter generates a group management frame including a group information and position information and a data frame including a group control information having a group identifier for each of a plurality of groups. The group information indicates whether the receiver is a member of each of the plurality of groups. The position information indicates a position of at least one stream corresponding to at least one group of which the receiver is a member.
Claims10
A method of transmitting in a wireless communication system, the method comprising:
- transmitting, by a transmitter, a data frame to a plurality of receivers, the data frame including group control information having a group identifier and stream information;
- and
- receiving, by the transmitter, a first reception acknowledgement for the data frame from a first receiver of the plurality of the receivers,
- wherein the group identifier indicates a group to which the plurality of receivers belong, and
- wherein the stream information indicates at least one spatial stream for each of the plurality of receivers.
A device in a wireless communication system, the apparatus comprising:
- a processor;
- and
- a memory operatively coupled with the processor and storing instructions that when executed by the processor causes to the device to:
- transmit a data frame to a plurality of receivers, the data frame including group control information having a group identifier and stream information;
- and
- receive a first reception acknowledgement for the data frame from a first receiver of the plurality of the receivers,
- wherein the group identifier indicates a group to which the plurality of receivers belong, and
- wherein the stream information indicates at least one spatial stream for each of the plurality of receivers.
