Redcap UE Operating Mode Switching for Bandwidth and Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Redcap UEs face challenges in operating modes that align with the requirements of R18 UEs, particularly in terms of bandwidth support and coverage enhancement, leading to inefficiencies and compatibility issues.
Innovation Solution
The method involves determining that Redcap UEs operate in a first operating mode with a maximum bandwidth less than or equal to that of a second operating mode, allowing them to adapt to narrower bandwidths and enhance coverage by reducing RF and baseband capabilities, and utilizing system message blocks and report information to facilitate this transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If Redcap UEs operate in a second operating mode with larger bandwidth, then data transmission rate is improved, but coverage capability deteriorates
Solution Approach 1:
The patent implements dynamic operating mode switching, allowing the Redcap UE to transition between first operating mode (narrower bandwidth, better coverage) and second operating mode (larger bandwidth, higher data rate) based on real-time network conditions and service requirements. This dynamic adaptation resolves the contradiction by enabling the system to optimize for coverage when needed and for speed when conditions permit.
2Device complexity
If Redcap UEs reduce RF and baseband capabilities to meet low cost and low complexity requirements, then device complexity is reduced, but adaptability to different operating modes deteriorates
Solution Approach 1:
The patent designs the Redcap UE with multi-functional capabilities that enable it to operate in both first operating mode (narrower bandwidth) and second operating mode (larger bandwidth) using the same reduced-capability hardware. The UE can universally handle different operating modes through software configuration and mode switching, resolving the contradiction between reduced hardware complexity and maintained adaptability.
3Ease of manufacture
If Redcap UEs support antenna structure of one RX or two RXs to reduce cost, then device cost is reduced, but communication reliability deteriorates
Solution Approach 1:
The patent implements dynamic operating mode switching that allows the Redcap UE to adapt its communication parameters based on the configured antenna structure. Whether the UE has one RX or two RXs, the system can dynamically adjust operating modes to maintain communication reliability while keeping hardware costs low, resolving the contradiction between ease of manufacture and communication reliability.
