1. An apparatus for wireless communication comprising:
- an electronic hardware processor configured to generate a clear to transmit message comprising a first indication of an uplink transmission opportunity, the clear to transmit message further comprising a request for two or more stations to concurrently transmit uplink data at a specific time, the clear to transmit message further comprising a common information field including information common to all of the two or more stations, the clear to transmit message further comprising two or more individual information fields corresponding to each of the two or more stations respectively, the clear to transmit message further comprising a duration field indicating a length for a plurality of uplink data transmissions to be received from the two or more stations at the specific time, wherein the indicated length corresponds to a number of orthogonal frequency-division multiplexing symbols;
a transmitter configured to transmit the clear to transmit message to the two or more stations; and
a receiver configured to receive the plurality of uplink data transmissions at the specific time from at least two stations of the two or more stations.

Abstract
Methods and apparatus for multiple user uplink are provided. In one aspect, a method for wireless communication is provided. The method includes transmitting a clear to transmit (CTX) message to two or more stations, the CTX indicating an uplink transmission opportunity, the CTX message further comprising a request that the two or more stations concurrently transmit uplink data at a specific time. The method further includes receiving a plurality of uplink data from at least two stations at the specific time.
