Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face increased complexity and power consumption when handling extended bandwidths, higher modulation orders, and multiple spatial streams, leading to inefficiencies in access points and stations.
Innovation Solution
The implementation of processing circuitry that reuses resources by generating and rearranging data streams across different frequency bands and spatial streams, allowing for efficient processing of wireless signals in extended bandwidths without significant increases in area or power consumption, using a combination of segment parsers, tone mappers, and spatial demappers within the transceiver and processing circuitry.

Engineering Contradiction Analysis
1Use of energy by stationary object
If resources are reused in extended bandwidth, then area and power consumption are reduced, but processing complexity increases
Solution Approach 1:
The stream deparser is designed to perform multiple functions by handling different reception modes (first and second reception modes) with different bandwidths and MIMO configurations using the same hardware resource. This multi-functionality allows the system to reduce overall hardware requirements while maintaining support for various operational modes, directly addressing the contradiction between reduced power consumption and maintained processing capability.
Solution Approach 2:
The system dynamically switches between different reception modes (first and second reception modes) depending on the operational requirements. The stream deparser adapts its processing behavior based on the mode being used, allowing flexible resource utilization. This dynamic operation enables the system to optimize performance for specific scenarios while using the same hardware foundation, resolving the tension between reduced complexity and maintained functionality.
