Abstract
Uplink transmission in a wireless local area network is provided. A station receives a trigger frame for requesting a transmission of an uplink physical layer protocol data unit (PPDU) from an access point (AP). The station determines a value of a second duration field of an uplink PPDU based on a first duration field of the trigger frame. The station transmits the uplink PPDU. The uplink PPDU does not include any frame that solicits a response frame from the AP when the value of the second duration field is set to zero.
Claims8
A method for a wireless local area network, the method performed by an access point (AP) comprising:
- transmitting information about a first basic service set (BSS) color to a station, the first BSS color identifying a BSS managed by the AP;
- transmitting a first physical layer protocol data unit (PPDU) to the station, the first PPDU including a second BSS color and a first duration field, wherein the second BSS color matches with the first BSS color and the first PPDU requests a transmission of a second PPDU;
- and
- receiving the second PPDU from the station as a response to the first PPDU, the second PPDU including a second duration field,
- wherein the first duration field of the first PPDU indicates an estimated time required to transmit the second PPDU,
- wherein the second PPDU does not include any frame that solicits a control response frame to be sent by the AP when a value of the second duration field is set to zero, and
- wherein the control response frame includes an acknowledgement frame for acknowledging the second PPDU.
A device comprising:
- a transceiver configured to receive and transmit radio signals;
- and
- a processor coupled with the transceiver and configured to:
- control the transceiver to transmit information about a first basic service set (BSS) color to a station, the first BSS color identifying a BSS managed by the device;
- control the transceiver to transmit a first physical layer protocol data unit (PPDU) to the station, the first PPDU including a second BSS color and a first duration field, wherein the second BSS color matches with the first BSS color and the first PPDU requests a transmission of a second PPDU;
- and
- control the transceiver to receive the second PPDU from the station as a response to the first PPDU, the second PPDU including a second duration field,
- wherein the first duration field of the first PPDU indicates an estimated time required to transmit the second PPDU,
- wherein the second PPDU does not include any frame that solicits a control response frame to be sent by the device when a value of the second duration field is set to zero, and
- wherein the control response frame includes an acknowledgement frame for acknowledging the second PPDU.
