Abstract:
1. A method of transmitting data from a mobile station to an access point, the method comprising: generating, by the mobile station, a Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU) including a Very High Throughput Signal (VHT-SIG) field and a PLCP Service Data Unit (PSDU); and transmitting, by the mobile station, the PPDU to the access point, wherein the VHT-SIG field includes a class type and an identifier field, wherein the class type indicates whether a transmission type of the PPDU is an uplink transmission or a downlink transmission, and wherein the identifier field indicates a partial identifier formed from a Basic Service Set Identifier (BSSID) that identifies the access point when the class type indicates that the transmission type of the PPDU is the uplink transmission, the partial identifier having a length shorter than a length of the BSSID.
