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.
Claims17
A method for uplink transmission in a wireless local area network, the method comprising:
- establishing, by a station, a connection with an access point (AP);
- receiving, by the station, information about a first basic service set (BSS) color identifying a BSS managed by the AP;
- receiving, by the station, a first physical layer protocol data unit (PPDU), the first PPDU including a second BSS color and a first duration field;
- comparing, by the station, the first BSS color and the second BSS color to determine whether or not the received first PPDU is from the AP;
- and
- when the second BSS color matches with the first BSS color and the first PPDU requests a transmission of a second PPDU, transmitting, by the station, the second PPDU to the AP 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 for uplink transmission in a wireless local area network, the 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 establish a connection with an access point (AP);
- control the transceiver to receive information about a first basic service set (BSS) color identifying a BSS managed by the AP;
- control the transceiver to receive a first physical layer protocol data unit (PPDU), the first PPDU including a second BSS color and a first duration field;
- compare the first BSS color and the second BSS color to determine whether or not the received first PPDU is from the AP;
- and
- control the transceiver to transmit a second PPDU to the AP as a response to the first PPDU when the second BSS color matches with the first BSS color and the first PPDU requests a transmission of the second 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 method for uplink transmission in a wireless local area network, the method comprising:
- receiving, by a station, a trigger frame for requesting a transmission of an uplink physical layer protocol data unit (PPDU) from an access point (AP), the trigger frame including a resource unit allocation and a first duration field, the resource unit allocation indicating at least one resource unit used for the transmission of the uplink PPDU, the first duration field indicating an estimated time required to transmit the uplink PPDU;
- and
- transmitting, by the station, the uplink PPDU to the AP as a response to the trigger frame, the uplink PPDU including a second duration field,
- wherein the uplink 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 uplink PPDU.
