Abstract: The present invention provides a wireless communication circuitry including a processor, a communication path and a channel detection path. The communication path is configured to wirelessly communicate with an electronic device by using a first channel. The channel detection path is configured to detect at least one channel different from the first channel to generate a detection result while the communication path is wirelessly communicating with the electronic device by using the first channel. The processor determines a second channel based on the detection result, and the processor controls the communication path to switch to the second channel from the first channel to communicate with the electronic device.

Abstract: A packet receiving method is provided. The packet receiving method includes the following steps: during receipt of the first packet by a receiver, detecting if any packet arrives at the receiver after a first packet; and when it is detected that a second packet arrives at the receiver during the receipt of the first packet, determining whether to decode the first packet or the second packet.

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.
