BANDWIDTH DETERMINATION FOR MULTIPLE USER TRANSMISSION IN A HIGH EFFICIENCY WIRELESS LAN
First Claim
1. A method for transmitting by a station (STA) to an access point (AP) an uplink Physical layer Protocol Data Unit (PPDU) frame in a wireless local area network, the method comprising:
- receiving a trigger frame including bandwidth information, the trigger frame eliciting a transmission of the uplink PPDU frame including a data unit of the STA and at least one data unit of at least one other STA; and
transmitting the data unit of the STA in the uplink PPDU frame, based on an available bandwidth of the STA and a bandwidth indicated by the bandwidth information included in the trigger frame.

Abstract
The present disclosure relates to a method and apparatus for determining a bandwidth for Multi-User (MU) transmission in a High Efficiency WLAN (HEW). According to one aspect of the present disclosure, a method for transmitting by a Station (STA) to an Access point (AP) an uplink Physical layer Protocol Data Unit (PPDU) frame in a WLAN may be provided. The method may include receiving a trigger frame including bandwidth information, the trigger frame eliciting a transmission of the uplink PPDU frame including a data unit of the STA and at least one data unit of at least one other STA, and transmitting the data unit of the STA in the uplink PPDU frame, based on an available bandwidth of the STA and a bandwidth indicated by the bandwidth information included in the trigger frame.

17. A method for receiving by an access point (AP) from a plurality of stations (STAs) an uplink Physical layer Protocol Data Unit (PPDU) frame in a wireless local area network, the method comprising:
-
transmitting to the plurality of STAs a trigger frame including bandwidth information, the trigger frame eliciting a transmission of the uplink PPDU frame including a plurality of data units of the plurality of STAs; and receiving the plurality of data units of the plurality of STAs in the uplink PPDU frame, the transmission of the uplink PPDU frame being determined by each of the plurality of STAs based on an available bandwidth of the each of the plurality of STAs and a bandwidth indicated by the bandwidth information included in the trigger frame. - View Dependent Claims (18, 19, 20)
