Method and apparatus for processing PPDU based on BSS identification information in a high efficiency wireless LAN

An apparatus for facilitating wireless communication, the apparatus comprising:

• one or more memories;
• and
• one or more processors coupled to the one or more memories, the one or more processors configured to cause:
• determining, using BSS identification information included in a High Efficiency Signal A (HE-SIG-A) field of a first Physical layer Protocol Data Unit (PPDU), whether the first PPDU is transmitted from a different Basic Service Set (BSS) from a BSS to which the STA belongs or a same BSS as the BSS to which the STA belongs;
• and
• processing the first PPDU,
• wherein processing the first PPDU comprises:
• processing the first PPDU using a first type of Clear Channel Assessment (CCA) threshold when the first PPDU is determined to be transmitted from the different BSS, and
• processing the first PPDU using a second type of CCA threshold when the first PPDU is determined to be transmitted from the same BSS,
• wherein the first type of CCA threshold is greater than a second type of CCA threshold.
