RELATIVE TIMING DRIFT CORRECTION FOR DISTRIBUTED MULTI-USER TRANSMISSIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18062839 titled 'RELATIVE TIMING DRIFT CORRECTION FOR DISTRIBUTED MULTI-USER TRANSMISSIONS
Simplified Explanation
The patent application describes a system for correcting timing drift in distributed multi-user transmissions.
- The system involves two access points (APs) communicating with each other.
- The first AP receives a signal from the second AP, which is associated with a channel sounding procedure.
- The first AP then receives a second signal from the second AP, which includes timing information relative to the first signal.
- Based on this timing information, the first AP determines the start time of a simultaneous transmission between the two APs.
- The first AP initiates the simultaneous transmission according to the determined start time.
Potential Applications
- Wireless communication networks
- Internet of Things (IoT) devices
- Mobile devices and networks
Problems Solved
- Timing drift in distributed multi-user transmissions
- Ensuring synchronized transmissions between access points
Benefits
- Improved efficiency and reliability of wireless communication
- Reduced interference and collisions in multi-user environments
- Enhanced performance of IoT devices and mobile networks
Original Abstract Submitted
This disclosure provides systems, methods, apparatus, and computer programs encoded on computer storage media, for relative timing drift correction for distributed multi-user transmissions. In one aspect, a first access point (AP) may receive a first signal from a second AP. The first signal may be associated with a channel sounding procedure to be performed substantially simultaneously by the second AP and the first AP. The first AP may then receive a second signal from the second AP, and prior to a substantially simultaneous transmission by the second AP and the first AP. The second signal may include timing information relative to the first signal. The first AP may determine a start time of the substantially simultaneous transmission at the first AP based on the timing information, and may initiate the substantially simultaneous transmission according to the determined start time.
