Patent number: 11736245Abstract: A wireless device performs spatial reuse in a wireless local area network. When receiving a packet, the wireless device measures a received signal quality from a first portion of the packet, and determines a required signal quality for correctly decoding a payload of the packet based on information in a packet header. The wireless device compares the received signal quality with the required signal quality. If the received signal quality is lower than the required signal quality, the wireless device transmits a signal that overlaps in time and in frequency with a second portion of the packet. Alternatively, a wireless device may identify a Basic Service Set Identification (BSSID) of a received packet. If the BSSID indicates that the packet is an inter-BSS packet, the wireless device transmits a signal overlapping in time and in frequency with the packet before reception of a frame check sequence (FCS) in the packet.Type: GrantFiled: December 26, 2019Date of Patent: August 22, 2023Assignee: MediaTek Inc.Inventors: Ray-Kuo Lin, Tsungjung Lee, Fu-yu Tsai, Wei-Chen Wang
