ACCESS MANAGEMENT TO MULTI-USER UPLINK RANDOM RESOURCE UNITS BY A PLURALITY OF BSSs - A simplified explanation of the abstract
This abstract first appeared for US patent application 18464117 titled 'ACCESS MANAGEMENT TO MULTI-USER UPLINK RANDOM RESOURCE UNITS BY A PLURALITY OF BSSs
Simplified Explanation
The present invention is a wireless communication method in a wireless network that includes an access point and stations. The method involves the following steps:
- Receiving a trigger frame from the access point, which reserves a transmission opportunity on at least one communication channel of the wireless network. This transmission opportunity includes a random resource unit that the stations can access using a contention scheme.
- Receiving parameters of the contention scheme in management frames from the access point. These parameters include a contention window range.
- Contending access to the random resource unit of the reserved transmission opportunity using a contention window value.
- Updating the contention window value based on the success or failure of the access to the random resource unit.
- The updated contention window value remains within the contention window range obtained from the most recently received contention scheme parameters.
Potential applications of this technology:
- Wireless networks: This method can be applied to improve the efficiency and reliability of wireless communication in various types of wireless networks, such as Wi-Fi networks or cellular networks.
Problems solved by this technology:
- Contentions in wireless networks: The method addresses the issue of multiple stations contending for access to the same transmission opportunity in a wireless network. By using a contention scheme and updating the contention window value, the method helps to reduce collisions and improve overall network performance.
Benefits of this technology:
- Improved network efficiency: By reserving transmission opportunities and using a contention scheme, the method helps to minimize collisions and maximize the utilization of the wireless network resources.
- Enhanced reliability: The method's ability to update the contention window value based on the success or failure of access to the random resource unit helps to ensure reliable communication and reduce packet loss in the wireless network.
Original Abstract Submitted
The present invention relates to a wireless communication method in a wireless network comprising an access point and stations. The method comprises, at a station: receiving a trigger frame from the access point, the trigger frame reserving a transmission opportunity on at least one communication channel of the wireless network, the transmission opportunity including a random resource unit that the stations may access using a contention scheme; receiving parameters of the contention scheme in management frames from the access point, the parameters comprising a contention window range; contending access to the random resource unit of the transmission opportunity reserved by the received trigger frame, using a contention window value; and updating the contention window value based on the success or failure of the access to the random resource unit. The updated contention window value remains within the contention window range obtained from the most recently received contention scheme parameters.
