  • Patent number: 11736245
    Abstract: 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.

  • Publication number: 20170034830
    Abstract: A wireless communication device has an antenna module, a synthesizer module, and a control unit. The antenna module has at least a first antenna set and a second antenna set. The synthesizer module is coupled to the antenna module, and has at least a first synthesizer and a second synthesizer. The control unit is coupled to the synthesizer module. While a station wirelessly connects to the wireless communication device via the first antenna set coupled to the first synthesizer in a first channel, the control unit checks at least one channel via the second antenna set coupled to the second synthesizer to find a second channel that is different from the first channel and has a better channel quality than a channel quality of the first channel.
