COORDINATED TIME DOMAIN MULTIPLE ACCESS (TDMA) AMONG ACCESS POINTS (APS) WITH DIFFERENT CHANNELS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17940867 titled 'COORDINATED TIME DOMAIN MULTIPLE ACCESS (TDMA) AMONG ACCESS POINTS (APS) WITH DIFFERENT CHANNELS

Simplified Explanation

The patent application describes a system for wireless communication using Coordinated Time Domain Multiple Access (C-TDMA) among access points with different channels.

• Wireless communication system using C-TDMA
• Access points with different channels
• Control message with scheduling information for transmission opportunity (TXOP)
• Clear Channel Assessment (CCA) for overlapping and non-overlapping portions
• Transmitting on overlapping and different bandwidths during TXOP

Potential Applications

• Wireless networks
• Internet of Things (IoT) devices
• Smart home systems

Problems Solved

• Efficient use of bandwidth
• Coordinated communication among access points
• Avoiding interference in wireless networks

Benefits

• Improved network performance
• Enhanced reliability of wireless communication
• Optimal utilization of available bandwidth

Original Abstract Submitted

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communication, including coordinated time domain multiple access (C-TDMA) among access points (APs) with different channels. In one aspect, while using C-TDMA, a first AP may receive a control message with scheduling information for a transmission opportunity (TXOP) from a second AP, which is the TXOP owner. The second AP may operate in a certain bandwidth, and first AP may operate in an overlapping portion of the same bandwidth, and also a different portion of bandwidth. The scheduling information may indicate a portion of the TXOP for the first AP to use during the TXOP. During the portion of the TXOP for the first AP, the first AP may perform a clear channel assessment (CCA) for the overlapping and non-overlapping portions, and transmit on both the overlapping and different bandwidths during the TXOP.
