Information Transmission Configuration for Multi-TRP Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-TRP scenarios, the differing positions of transmission and reception points relative to user equipment cause delays in data reception, leading to data overlap and interference, which affects communication quality.
Innovation Solution
A configuration method for information transmission that involves setting a transmission interval K between downlink or uplink transmissions in multi-TRP scenarios, reducing the probability of data overlap and enhancing network communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple TRPs transmit data simultaneously without coordination, then transmission throughput is improved, but data overlap and interference occur due to different propagation delays
Solution Approach 1:
The network side performs preliminary calculation of propagation delays between different TRPs and the UE, and pre-configures time offset parameters to adjust transmission timing before actual data transmission occurs, preventing data overlap in advance
Solution Approach 2:
The patent introduces and adjusts the time offset parameter (K) to change the transmission timing of different TRPs, dynamically controlling the transmission time based on calculated propagation delays to ensure non-overlapping reception at the UE
2Reliability
If transmission interval K is increased to avoid data overlap, then data reception reliability is improved, but transmission efficiency decreases
Solution Approach 1:
The patent dynamically adjusts the time offset parameter K based on the specific propagation delay conditions between TRPs and UE, optimizing the transmission interval to be just sufficient to avoid overlap while minimizing idle time, thus balancing reliability and efficiency
3Measurement precision
If different timing advances are used for different TRPs to account for position differences, then transmission accuracy is improved, but uplink transmission overlap occurs due to TA differences
Solution Approach 1:
The network side acts as an intermediary to coordinate uplink transmissions from UE to different TRPs by configuring appropriate time offsets, mediating the timing conflicts caused by different TA values and preventing uplink data overlap at the network side
