  • Wireless communication circuit with scheduling circuit in MAC layer
    Patent number: 10701001
    Abstract: A wireless communication circuit includes: a physical-layer circuit, arranged to operably communicate with other wireless communication devices through an antenna; a micro-controller, arranged to operably generate data frames to be transmitted to other wireless communication devices; and a MAC-layer circuit comprising: a MAC-layer storage circuit for storing a data queue; a MAC-layer control circuit, coupled with the physical-layer circuit, the micro-controller, and the MAC-layer storage circuit, arranged to temporarily store the data frames generated by the micro-controller in the data queue; and a scheduling circuit, coupled with the MAC-layer storage circuit and the MAC-layer control circuit, arranged to operably schedule a timing that the MAC-layer control circuit transmits data stored in the data queue to the physical-layer circuit.
