TRP Mode Configuration via DCI Bit Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently configuring transmission reception point (TRP) mode for optimal communication performance, particularly in scenarios requiring dynamic switching between single-TRP and multi-TRP configurations.
Innovation Solution
The method involves transmitting and receiving an indication of a number of bits in a downlink control information (DCI) message to configure the TRP mode for subsequent communications, allowing for flexible configuration of TRP modes based on communication protocols and higher-layer signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dynamic TRP mode configuration is implemented, then communication reliability and throughput are improved, but device complexity increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the number of bits in DCI messages to indicate different TRP mode configurations. The system transitions between single-TRP and multi-TRP modes by modifying bit allocation parameters in control information, enabling flexible adaptation to varying communication conditions without requiring complex reconfiguration procedures.
Solution Approach 2:
The patent implements dynamics by enabling real-time switching between different TRP modes (single-TRP and multi-TRP) based on current network conditions. The base station dynamically determines the number of bits to use in DCI messages, allowing the system to adapt TRP configuration dynamically rather than being fixed, thereby improving reliability while managing complexity through controlled flexibility.
2Adaptability or versatility
If multi-TRP configuration options are added, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent uses parameter changes to manage adaptability by varying the number of bits allocated for TRP mode indication in DCI messages. Instead of using a fixed complex configuration structure, the system adapts to different TRP scenarios (single-TRP or multi-TRP) by adjusting bit parameters, thereby achieving versatility while keeping the configuration mechanism relatively simple and manageable.
3Measurement precision
If bit allocation for TRP indication is increased, then measurement precision is improved, but loss of energy increases
Solution Approach 1:
The patent applies parameter changes to optimize the trade-off between precision and energy by dynamically adjusting the number of bits used for TRP mode indication. The base station determines the appropriate bit allocation based on current communication needs, using more bits only when multi-TRP configuration is required and fewer bits when single-TRP mode suffices, thereby achieving necessary precision while minimizing energy consumption.
Solution Approach 2:
The patent implements partial action by using a variable number of bits rather than always allocating maximum bits for TRP indication. The system uses only the necessary number of bits (0, 1, or 2 bits) based on the specific TRP configuration scenario, avoiding excessive bit allocation and the associated energy consumption while still achieving the required precision for the given communication conditions.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a number of bits to be used in a downlink control information (DCI) message, the bits configured to indicate a transmission reception point (TRP) mode configuration for one or more subsequent communications. The UE may receive the DCI message having the number of bits to indicate the TRP mode configuration for the subsequent communications. Numerous other aspects are described.
