Multi-Band Transmission Switching Capability for Stable 5G NR Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Uplink transmission switching in 5G NR systems across multiple bands causes downlink interruptions and throughput performance degradation due to frequent and unpredictable switching events, particularly in Release 18 (R18) with 3 or 4 bands.
Innovation Solution
A method where a first device indicates its transmission switching capability across multiple bands to a second device, allowing for a flexible and efficient configuration of transmission switching based on the device's ability to perform switching, thereby reducing performance degradation by minimizing interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uplink transmission switching is extended across 3 or 4 bands in Release 18, then uplink transmission capability and flexibility are improved, but downlink interruptions increase and throughput performance degrades
Solution Approach 1:
The patent applies preliminary action by having the UE indicate its transmission switching capability to the network in advance, allowing the network to pre-configure appropriate switching parameters and downlink adjustments before actual switching events occur. This proactive configuration reduces the impact of switching on downlink performance.
Solution Approach 2:
The patent implements dynamics by enabling dynamic indication of transmission switching capability from the UE to the network, allowing the system to adapt switching behavior based on real-time capability reporting. The network can dynamically adjust downlink configuration based on UE capability indications to minimize interruptions.
2Adaptability or versatility
If frequent transmission switching is performed across multiple bands, then uplink flexibility and adaptability are improved, but downlink interruptions increase
Solution Approach 1:
The patent applies feedback by having the UE indicate its transmission switching capability to the network, creating a feedback loop where the network receives real-time capability information and adjusts downlink configuration accordingly. This feedback mechanism allows the system to optimize switching frequency and timing to minimize downlink interruptions.

AI summary
Example embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage medium for extended capability for transmission switching. In a method, a first device transmits, to a second device, at least one indication of capability for transmission switching across a plurality of bands. The at least one indication is related to at least frequency of the transmission switching allowed by the first device. The first device receives, from the second device, a configuration for the transmission switching.
