Abstract: The application provides a wireless communication method and device for spatial reuse. A heading information of a current-received data packet is decoded by a spatial reuse (SR) initiator device. Based on a decoding result, the SR initiator device determines to initiate SR. The SR initiator device drops the current-received data packet. The SR initiator device transmits a dummy leading signal to a SR response device. The SR initiator device transmits a spatial reuse data packet to the SR response device.

Abstract: A wireless device control circuit with modularized internal circuit architecture and associated wireless communications device are provided. The wireless device control circuit may include a first digital processing circuit and a second digital processing circuit. The first digital processing circuit is arranged to perform first digital processing corresponding to a first predetermined radio frequency band for the wireless communications device, the first digital processing including common processing and a first additional processing. The second digital processing circuit is arranged to perform second digital processing corresponding to a second predetermined radio frequency band for the wireless communications device, the second digital processing including the common processing and a second additional processing.
