Techniques to identify packets associated with an overlapping basic service set
First Claim
1. A method of wireless communication at a wireless device associated with an overlapping basic service set (OBSS), comprising:
- receiving a wireless local area network (WLAN) packet comprising a preamble and a data region;
attempting to identify whether the preamble comprises a first identification mechanism associated with the OBSS;
determining, based at least in part on the attempting, that there is insufficient information to decide that the wireless local area network (WLAN) packet is associated with the OBSS;
decoding at least a portion of the data region based at least in part on the determining, wherein the decoding comprises decoding a media access control (MAC) header within the data region;
identifying a second OBSS identification mechanism based at least in part on the decoding; and
determining that the WLAN packet is associated with the OBSS based at least in part on the second OBSS identification mechanism and based at least in part on the decoded medium access control (MAC) header.

Abstract
A wireless device may utilize enhanced OBSS identification techniques to determine whether an interfering transmission is associated with an OBSS. In an example, a wireless device may receive a WLAN packet that includes a preamble and a data region. The wireless device may analyze the preamble to determine whether the WLAN packet is an OBSS packet. If the wireless device determines there is insufficient information in the preamble to identify the WLAN packet as an OBSS packet, the wireless device may decode a portion of the data region (e.g., a MAC header) to determine if the WLAN packet is an OBSS packet. Prior to declaring a successful decoding of the MAC header, the wireless device may confirm the MAC header has been received reliably. Additionally or alternatively, BSS identifiers may be included in the data region and used to determine if the WLAN packet is associated with an OBSS.

7. A method of wireless communication at a wireless device associated with an overlapping basic service set (OBSS), comprising:
-
generating a wireless local area network (WLAN) packet comprising a preamble and a data region; determining whether to include in the preamble a first identification mechanism associated with the OBSS; generating, based at least in part on the determining, a second identification mechanism associated with the OBSS, wherein the second identification mechanism comprises an indication that the WLAN packet is associated with the OBSS, for a user equipment (UE) to decode the data region to determine that the WLAN packet is associated with the OBSS; inserting, based at least in part on the generating, the second identification mechanism into a portion of the data region associated with the WLAN packet; and transmitting the WLAN packet over a channel that is shared with the OBSS. - View Dependent Claims (8, 9, 10, 11)
