Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies, such as LTE and NR, face challenges in efficiently managing bandwidth and switching between single-TRP and multi-TRP modes within a bandwidth part (BWP), limiting flexibility and performance in mobile broadband access.
Innovation Solution
Implementing a method to dynamically configure user equipment (UE) to operate in either single-TRP or multi-TRP modes based on bandwidth part switches or triggers, using radio resource control (RRC) signaling, downlink control information (DCI), and medium access control (MAC) configurations, allowing for efficient switching between modes to optimize power saving, reliability, and throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dynamic mode switching between single-TRP and multi-TRP is implemented, then operational efficiency and adaptability are improved, but device complexity and configuration management difficulty increase
Solution Approach 1:
The patent implements dynamic switching between single-TRP and multi-TRP modes based on real-time conditions. The UE can transition between operational modes depending on bandwidth part configurations, trigger conditions, and network requirements, making the system adaptable rather than static. This resolves the contradiction by enabling versatility through dynamically configurable parameters.
Solution Approach 2:
The patent changes operational parameters (TRP mode, bandwidth part, trigger conditions) to achieve mode switching. By modifying these parameters based on network conditions and requirements, the system achieves adaptability without requiring fundamentally different device architectures, thus managing complexity through parameter adjustment rather than structural complexity.
2Reliability
If multi-TRP mode is used to improve reliability and throughput, then communication performance is enhanced, but power consumption and device complexity increase
Solution Approach 1:
The patent enables dynamic switching between single-TRP and multi-TRP modes based on trigger conditions and network requirements. The UE operates in multi-TRP mode only when needed (upon receiving triggers or meeting specific conditions), rather than continuously, thus achieving improved reliability when necessary while conserving power during normal operation. This temporal dynamics resolves the contradiction between reliability enhancement and power consumption.
3Productivity
If frequent mode switching is performed to optimize performance, then adaptability and throughput are improved, but processing overhead and device complexity increase
Solution Approach 1:
The patent configures trigger conditions and parameters in advance before mode switching is needed. The network pre-configures the UE with multiple bandwidth parts, trigger conditions, and mode parameters, so that when switching is required, the UE can execute the pre-planned configuration changes efficiently. This preliminary preparation reduces processing overhead during actual mode transitions while maintaining throughput optimization capabilities.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may determine to configure a user equipment (UE) to operate in a transmission/reception point (TRP) mode, wherein the TRP mode is a single-TRP mode or a multi-TRP mode. The BS may configure the UE to operate in the TRP mode based at least in part on a bandwidth part (BWP) switch or a trigger to switch between the multi-TRP mode and the single-TRP mode within a BWP. Numerous other aspects are provided.
