Wireless Repeater Primary Base Station Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless repeaters face challenges in simultaneously receiving control information from multiple base stations due to directional beams and lack of coordination, leading to complex communication management and potential interference.
Innovation Solution
Implementing a method where one base station acts as a primary to transmit control information to a wireless repeater on behalf of other base stations, using a coordinated control signaling pattern with defined time intervals to ensure efficient communication with user equipment (UEs) connected to each base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless repeater monitors control information from multiple base stations simultaneously, then communication coverage and connectivity are improved, but device complexity and interference management become worse
Solution Approach 1:
The patent introduces a primary base station as an intermediary that consolidates control information from multiple base stations and transmits it to the wireless repeater through a single coordinated interface. This mediator approach allows the repeater to maintain connectivity with multiple base stations without having to independently manage control information from each one, thereby reducing device complexity while preserving communication coverage.
2Adaptability or versatility
If control information is transmitted from multiple base stations to a wireless repeater without coordination, then communication versatility is improved, but harmful interference and signal quality deteriorate
Solution Approach 1:
The patent implements periodic time division multiplexing where the primary base station transmits control information to the wireless repeater at specific time intervals according to a predetermined pattern. This periodic action ensures that control information from multiple base stations is transmitted in a coordinated manner, preventing simultaneous transmissions that would cause interference while maintaining the ability to communicate with multiple base stations.
3Reliability
If a wireless repeater monitors control information from multiple base stations independently, then communication reliability is improved, but loss of time and processing overhead increase
Solution Approach 1:
The patent merges control information from multiple base stations into a single consolidated transmission stream through the primary base station. Instead of the wireless repeater independently monitoring and processing control information from each base station separately, all control information is combined and transmitted through one coordinated interface, significantly reducing processing time and overhead while maintaining communication reliability through the coordinated approach.

AI summary
Methods, systems, and devices for wireless communications are described. A wireless repeater may communicate with multiple base stations, and the wireless repeater may identify a first base station as a primary base station. The wireless repeater may monitor for and receive control information from the primary base station, where the control information may include control information from a second base station and used by the wireless repeater to communicate with one or more UEs connected to the second base station. The primary base station may receive an indication of the control information from the second base station via a backhaul link. In other examples, the wireless repeater may monitor for control information from the two or more base stations based on a control signaling pattern. For example, the wireless repeater may be configured with periodic time intervals for monitoring for control signaling from respective base stations.
