Solution Overview
Problem
Current wireless communication systems face limitations in channel assignment efficiency due to restrictions on channel use and frequency band utilization, particularly in OFDMA communication, where specific information needed for effective channel assignment is not adequately disclosed or collected from terminals.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a reference channel is used as a base for channel assignment, then channel management is simplified, but the number of terminals that can perform simultaneous communication is limited to one
Solution Approach 1:
The patent segments the single reference channel into multiple independent channel sets, where each channel set can be independently assigned to different terminals. This allows multiple terminals to communicate simultaneously on different channel sets while maintaining simplified management through the base reference channel structure.
Solution Approach 2:
The patent introduces a new dimension of channel assignment by creating multiple channel sets from the reference channel, enabling simultaneous communications across different channel dimensions rather than being restricted to a single channel timeline.
2Device complexity
If the number of frequency bands that can be used simultaneously is limited by hardware configuration, then RF circuit design is simplified, but channel utilization efficiency is reduced
Solution Approach 1:
The patent makes the RF circuit capable of operating universally across multiple frequency bands by removing the hardware limitation that restricted it to a single frequency band. The RF circuit can now be dynamically assigned to different frequency bands through the channel set mechanism, enabling it to serve multiple functions across different channels.
3Device complexity
If channel assignment is restricted based on reference channel and carrier sensing results, then channel access control is simplified, but channel assignment efficiency is reduced
Solution Approach 1:
The patent segments the single carrier sensing reference channel into multiple independent channel sets, each capable of independent carrier sensing and assignment. This allows the access control mechanism to operate on individual channel sets rather than being constrained by a single reference channel, improving assignment efficiency while maintaining simplified control logic.
Solution Approach 2:
The patent adds dimensional flexibility to channel assignment by creating multiple channel sets that can be independently managed. This allows the system to assign channels across different dimensional spaces rather than being restricted to a single reference channel dimension, improving overall channel utilization.
4Device complexity
If specific information for effective channel assignment is not collected from terminals, then terminal communication protocol is simplified, but base station channel assignment capability is reduced
Solution Approach 1:
The patent implements preliminary action by having terminals pre-report their channel set capabilities to the base station before actual channel assignment occurs. This allows the base station to have advance knowledge of terminal capabilities, enabling more effective channel assignment decisions without complicating the terminal protocol.

AI summary
According to one embodiment, integrated circuitry installed in a wireless communication device, includes a control circuitry. The control circuitry notifies a first information showing a number of channel sets each of which is a set of one or two or more consecutive channels out of a plurality of channels in a predetermined frequency band and among each of which the wireless communication device is able to separately transmit and receive a signal. The first information can be carrier sensing separation capability as part of a multi user multi channel scheme in WLAN.
