Abstract
Disclosed are methods and apparatuses for transmitting and receiving a frame in a WLAN. A method for transmitting a frame, performed in a first station, may comprise receiving a first PPDU; determining whether a BSS of the first PPDU is a BSS to which the first station belongs or a BSS to which the first station does not belong; when the BSS of the first PPDU is the BSS to which the first station does not belong and a received signal strength of the first PPDU is higher than a first threshold, setting a virtual carrier sensing by using information included in a preamble of the first PPDU. Therefore, performance of the WLAN can be enhanced.
Claims1
A method for transmitting a frame, performed in a first station, the method comprising:
- receiving a first physical layer convergence procedure protocol data unit (PPDU);
- determining whether a basic service set (BSS) of the first PPDU is a BSS to which the first station belongs or a BSS to which the first station does not belong;
- when the BSS of the first PPDU is the BSS to which the first station does not belong and a received signal strength of the first PPDU is higher than a first threshold, setting a virtual carrier sensing by using information included in a preamble of the first PPDU;
- and
- when the BSS of the first PPDU is the BSS to which the first station does not belong and the received signal strength of the first PPDU is lower than the first threshold, trying to obtain a transmission opportunity.
