Abstract
A STA may perform packet detection to detect a packet and decode a legacy preamble of the detected packet including a legacy short training field (L-STF), a legacy long training field (L-LTF), and a legacy signal (L-SIG) field. The STA may decode a high efficiency signal A (HE-SIG-A) field to obtain a first partial association identifier (PAID) comprising group information. If the decoded group information matches group information stored in a memory of the STA, the STA may decode a high efficiency (HE) preamble and a high efficiency signal B (HE-SIG-B) field of the detected packet. The HE-SIG-B field may include a station identifier within the group. When the group information is combined with the station identifier, the STA may determine an accurate address.
