Abstract

A method and device for transmitting data in a wireless local area network are provided. An access point receives a plurality of transmission opportunity (TXOP) requests for requesting a TXOP configuration from a plurality of transmission stations. The access point transmits a TXOP polling regarding the TXOP configuration to the plurality of transmission stations. The access point receives a plurality of data blocks from the plurality of transmission stations during the configured TXOP.

Claims

1. A method for transmitting data in a wireless local area network, the method comprising:

receiving, by an access point (AP), a plurality of transmission opportunity (TXOP) requests for requesting a TXOP configuration from a plurality of transmission stations;

transmitting, by the AP, a TXOP polling regarding the TXOP configuration to the plurality of transmission stations; and

receiving, by the AP, a plurality of data blocks from the plurality of transmission stations during the configured TXOP.

2. The method of claim 1, wherein the plurality of data blocks include a plurality of physical layer protocol data units (PPDUs).

3. The method of claim 1, wherein each of the plurality of TXOP requests includes information about a corresponding transmission station.

4. The method of claim 1, wherein each of the plurality of TXOP requests includes information about a channel through which a corresponding data block is transmitted.

5. The method of claim 1, wherein the TXOP polling includes a group identifier identifying the plurality of transmission stations.

6. The method of claim 1, further comprising:

transmitting, by the AP, an ACK regarding the plurality of data blocks to the plurality of transmission stations during the configured TXOP.

7. A device for a wireless local area network, the device comprising:

a radio frequency (RF) unit configured to transmit and receive radio signals; and

a processor connected to the RF unit and configured to;

instruct the RF unit to receive a plurality of transmission opportunity (TXOP) requests for requesting a TXOP configuration from a plurality of transmission stations;

instruct the RF unit to transmit a TXOP polling regarding the TXOP configuration to the plurality of transmission stations; and

instruct the RF unit to receive a plurality of data blocks from the plurality of transmission stations during the configured TXOP.

8. The device of claim 7, wherein the plurality of data blocks include a plurality of physical layer protocol data units (PPDUs).

9. The device of claim 7, wherein each of the plurality of TXOP requests includes information about a corresponding transmission station.

10. The device of claim 7, wherein each of the plurality of TXOP requests includes information about a channel through which a corresponding data block is transmitted.
