Switching Scheme for Opting In and Out of Multi-User Orthogonal Frequency-Division Multiple Access - A simplified explanation of the abstract
This abstract first appeared for US patent application 18219958 titled 'Switching Scheme for Opting In and Out of Multi-User Orthogonal Frequency-Division Multiple Access
Simplified Explanation
The patent application describes a method for switching between multi-user and single-user modes in a wireless network.
- The electronic device enters the multi-user mode to communicate over a shared-channel bandwidth.
- If the uplink-queue size exceeds a certain threshold, the device switches to the single-user mode.
- In the single-user mode, the device contends for a transmit channel to send uplink data.
Original Abstract Submitted
This document describes methods, devices, systems, and means for a switching scheme for opting in and out of multi-user orthogonal frequency-division multiple access (MU-OFDMA). In one aspect, an electronic device enters the MU-OFDMA mode to communicate via a wireless network over a shared-channel bandwidth. During the MU-OFDMA mode, the electronic device determines that an uplink-queue size is greater than a first threshold size. Responsive to the determining, the electronic device opts out of the MU-OFDMA mode and enters a single-user mode to contend for a transmit channel for transmitting uplink data.
