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.

Abstract: Methods and systems for reducing overhead paging are described. One example of such a method includes generating a compressed traffic indication map (TIM) element, the compressed TIM element comprising a partial virtual bitmap field constructed from at least one encoded block field that includes an encoded block information field identifying at least one encoding mode for encoded block information, and sending the compressed TIM element to an at least one station (STA) associated with the access point that supports at least one multiple basic service set identifier (BSSID). The method may also include, in response to the at least one encoding mode comprising an offset, length, bitmap (OLB) mode, encoding the encoded block information field to include a length subfield followed by contiguous subblock subfields, each subblock subfield including a corresponding subblock of a partial virtual map.
