Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face challenges in maintaining link quality due to signal interference and distance, leading to inefficient data transmission, especially with the advent of high-speed 5G NR technologies.
Innovation Solution
User equipment (UE) establishes direct peer-to-peer mmWave links with other UEs, coordinated by a base station, which allocates air interface resources and determines beam-forming procedures to enhance link quality and mitigate interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wireless communication systems rely on base station links for UE communication, then network management and resource allocation are simplified, but link quality degrades due to signal interference and distance
Solution Approach 1:
The base station acts as an intermediary that coordinates and manages peer-to-peer mmWave links between UEs. It allocates air interface resources, determines beam-forming procedures, and provides control signaling while the actual data transmission occurs directly between UEs through established mmWave links, combining centralized management with direct communication benefits
2Productivity
If UE establishes direct peer-to-peer mmWave links, then data throughput and link quality improve, but resource allocation and beam management complexity increases
Solution Approach 1:
The base station serves as a mediator that handles the complexity of resource allocation and beam management for peer-to-peer links. It determines air interface resource grants and beam-forming procedures, then provides these configurations to UEs via control signaling, allowing UEs to establish direct high-throughput mmWave links without managing the complexity themselves
3Ease of operation
If UE relies on base station for coordination, then beam selection and link establishment are simplified, but interference from nearby mmWave links increases
Solution Approach 1:
The base station acts as a coordinating intermediary that manages interference between multiple peer-to-peer mmWave links. It allocates air interface resources in a coordinated manner across different UE pairs and manages beam-forming procedures to direct energy spatially, reducing interference while maintaining simplified beam selection for UEs

AI summary
Techniques and apparatuses are described for enabling a base station to enable peer-to-peer communication among multiple user equipment (UE) over a mmWave link. The techniques described herein overcome challenges that the multiple UEs might otherwise face in trying to establish peer-to-peer links on their own. By relying on the base station to grant air interface resources for the UE to perform peer-to-peer communications with the UE, the UE can communicate directly with the other UE, independent of links that the UE or the other UE maintains with the base station. Furthermore, reliance on the base station may help the UE and the other UE mitigate interference from other nearby mmWave links that are separate from the peer-to-peer wave link. In addition, by relying on the base station to specify the beam sweeping pattern, beam acquisition by the UE and the other UE may be improved.
