Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack efficient mechanisms to utilize the capabilities of propagation environment elements, such as programmable metasurfaces and network-controlled repeaters, for optimizing radio wave propagation and reducing interference in mobile terminals.
Innovation Solution
A mobile terminal equipped with a receiver to receive propagation environment element information, a controller to select base stations based on this information, and a transmitter to transmit connection requests, enabling PEE-aware communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional base station selection methods are used, then the selection process is simple, but communication efficiency is reduced due to inability to utilize propagation environment elements
Solution Approach 1:
The network provides propagation environment element information to the mobile terminal in advance through system information blocks or dedicated signaling messages. This allows the terminal to perform PEE-aware base station selection before actual communication, improving communication efficiency without adding complexity during the selection moment
Solution Approach 2:
Propagation environment element information acts as an intermediary that bridges the mobile terminal and base stations. The terminal uses this information as a selection criterion to identify base stations with optimal PEE support, enabling efficient selection without direct complex interactions between terminal and multiple base stations
2Productivity
If propagation environment element information is provided for all base stations, then communication optimization is improved, but signaling overhead increases
Solution Approach 1:
Propagation environment element information is provided selectively for specific base stations rather than uniformly for all base stations. The network determines which base stations have PEE support and provides information only for those, enabling communication optimization while minimizing signaling overhead by avoiding redundant information transmission
3Object-affected harmful factors
If the mobile terminal selects base stations without PEE awareness, then the connection process is fast, but interference is increased and radio resource management is suboptimal
Solution Approach 1:
The mobile terminal performs PEE-aware base station selection in advance by evaluating propagation environment element information before establishing connections. This preliminary PEE-matched selection reduces interference from the outset and optimizes radio resource management, while the connection establishment itself remains efficient by using pre-evaluated base station choices
