Wireless Interference Management via Bandwidth Partitioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless networks in CBRS bands face interference issues, leading to potential revocation of allocated wireless bandwidth, as existing spectrum access systems struggle to manage interference effectively across multiple communication devices.
Innovation Solution
A communication management resource partitions allocated wireless bandwidth into virtual bandwidths, monitors interference, and dynamically adjusts communication modes, including device-to-device communication, to reduce interference and prevent bandwidth revocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the spectrum access system allocates wireless channels to multiple communication devices, then the productivity of the wireless network is improved, but wireless interference increases leading to potential bandwidth revocation
Solution Approach 1:
The patent partitions the allocated wireless bandwidth into multiple virtual bandwidths (first virtual bandwidth, second virtual bandwidth, etc.) to separately manage communications with different communication devices. This segmentation allows the system to control interference from each device individually, preventing cumulative interference from causing bandwidth revocation while maintaining overall network productivity.
2Object-affected harmful factors
If the system monitors and manages interference for each communication device, then wireless interference is reduced, but the device complexity increases
Solution Approach 1:
The patent introduces a communication management resource as an intermediary between the wireless base station and multiple communication devices. This intermediary component centralizes the interference management functions, monitoring interference levels and controlling conveyance of wireless communications. By consolidating management functions in a dedicated intermediary resource, the system reduces overall complexity compared to having each device independently manage interference.

AI summary
A communication management resource partitions allocated wireless bandwidth into a first portion (such as first virtual bandwidth or first bandwidth part) and a second portion (such as virtual bandwidth or second bandwidth part). The communication management resource determines wireless interference associated with transmission of first wireless communications over the different bandwidth portions such as from a wireless base station to multiple communication devices while in a first mode. Depending on the wireless interference determined during the first mode, the communication management resource controls conveyance of second wireless communications over the allocated wireless bandwidth to the multiple communication devices in a second mode. In one instance, the communication management system operates one or more communication devices in a device-to-device mode to alleviate wireless interference associated with use of the allocated wireless bandwidth.
