Wireless packet transmission method in lan systems
The patent US12075467B2 outlines a method and apparatus for transmitting and receiving packets in a wireless local area network (WLAN) system, specifically focusing on the management of contention-free periods (CFP) and contention periods (CP) by an access point (AP). The method involves broadcasting a beacon frame that includes allocation information for both CFP and CP to multiple stations (STAs). The AP receives uplink (UL) packets from a designated STA and transmits downlink (DL) packets to another STA, with the length of the CFP being determined by the number of STAs and the traffic access category. The method also includes provisions for prioritizing packet transmission based on queue status and access categories, which encompass various types of traffic such as video and voice.
Additionally, the patent describes the use of contention-free poll frames to facilitate communication with STAs that support multi-user, multi-input, multi-output (MU-MIMO) technology. The AP is configured to determine the size of UL packets and the timing for transmission based on the capabilities of the STAs. The method allows for efficient management of packet transmission, including the use of backoff values during the CP and the identification of STA capabilities through an association procedure. The AP can also receive high-speed data from a base station, ensuring that the quality of service (QoS) requirements of the STAs are met. Overall, the patent presents a structured approach to enhance packet transmission efficiency in WLAN systems.
