Abstract
The present disclosure provides a wireless communication method. The wireless communication method may be performed by a first apparatus and may include acquiring a transmit opportunity (TXOP) for transmitting a first physical layer protocol data unit (PPDU) with a first transmission power, limiting a second transmission power of a second apparatus for sharing the TXOP with the second apparatus, and transmitting the first PPDU to a third apparatus with the transmission power in the shared TXOP.
Claims24
A wireless communication method performed by a first apparatus, the method comprising:
- acquiring a transmit opportunity (TXOP) for transmitting a first physical layer protocol data unit (PPDU) with a first transmission power;
- determining a limit for a second transmission power of a second apparatus and sharing the TXOP with the second apparatus based at least in part on the determined limit for the second transmission power;
- and
- transmitting the first PPDU to a third apparatus with the first transmission power in the shared TXOP.

14-21. (canceled)
A wireless communication method performed by a second apparatus sharing a transmit opportunity (TXOP) with a first apparatus, the method comprising:
- outputting a frame comprising capability information and first transmission power information, the capability information indicating support for spatial reuse and the first transmission power information indicating a first transmission power of the frame;
- receiving second transmission power information from the first apparatus;
- and
- transmitting a physical layer protocol data unit (PPDU) in the TXOP to at least one third apparatus with a second transmission power equal to or lower than the first transmission power indicated by the first transmission power information.
A wireless communication method performed by a third apparatus receiving a physical layer protocol data unit (PPDU) in a transmit opportunity (TXOP) shared by a first apparatus and a second apparatus, the method comprising:
- determining a first path loss between the first apparatus and the third apparatus based on a first frame received from the first apparatus;
- determining a second path loss between the second apparatus and the third apparatus based on a second frame received from the second apparatus;
- transmitting information about the first path loss and the second path loss to the first apparatus;
- and
- receiving the PPDU in the TXOP from the first apparatus.
