METHODS FOR UPLINK MULTIUSER SIGNALING AND TRANSMISSION

摘要

A method implemented by an Access Point (AP) in a Wireless Local Area Network (WLAN) to initiate an uplink (UL) multi-user (MU) simultaneous transmission. The method includes generating a trigger frame that initiates the UL MU simultaneous transmission, where the trigger frame includes (1) a UL MU Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU) attributes field to indicate attributes pertaining to a UL MU PPDU transmitted to the AP during the UL MU simultaneous transmission that are common to a plurality of stations (STAs) that are scheduled to participate in the UL MU simultaneous transmission and (2) a STA Physical Layer Service Data Unit (PSDU) attributes field for a particular STA from the plurality of STAs to indicate attributes pertaining to the UL MU PPDU that are specific to the particular STA. The method further includes transmitting the trigger frame through a wireless medium.

1. A method implemented by an Access Point (AP) in a Wireless Local Area Network (WLAN) to initiate an uplink (UL) multi-user (MU) simultaneous transmission, the method comprising:
generating a trigger frame that initiates the UL MU simultaneous transmission, wherein the trigger frame includes (1) a UL MU Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU) attributes field to indicate attributes pertaining to a UL MU PPDU transmitted to the AP during the UL MU simultaneous transmission that are common to a plurality of stations (STAs) that are scheduled to participate in the UL MU simultaneous transmission and (2) a STA Physical Layer Service Data Unit (PSDU) attributes field for a particular STA from the plurality of STAs to indicate attributes pertaining to the UL MU PPDU that are specific to the particular STA, wherein the UL MU PPDU attributes field includes a guard interval subfield to indicate a guard interval that the plurality of STAs are to apply to one or more portions of the UL MU PPDU and wherein the STA PSDU attributes field for the particular STA includes an assignment subfield to indicate a transmission resource unit that the particular STA is to use to transmit a set of Media Access Control (MAC) Protocol Data Units (MPDUs) within the UL MU PPDU to the AP during the UL MU simultaneous transmission; and transmitting the trigger frame through a wireless medium.
