Solution Overview
Problem
Wireless communication systems face challenges in supporting multiple different Timing Advances (TAs) in multi-beam and multi-Transmitter Receiver Points (TRP)/panels scenarios, leading to complexities in configuring transmission parameters and potential overlap of uplink transmissions.
Innovation Solution
A method for transmitting a first information block related to both a first and a second Timing Advance, allowing the base station to configure transmission parameters rationally, including the use of separate SRS resource sets for each TA, and determining timing differences to avoid overlapping transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple different Timing Advances (TAs) are supported in multi-beam/TRP/panel scenarios, then transmission reliability and throughput are improved, but device complexity and configuration complexity increase
Solution Approach 1:
The patent segments the SRS resource sets into multiple groups, where each group is associated with a specific Timing Advance (TA). This segmentation allows the system to manage multiple TAs independently through separate resource sets, thereby improving transmission reliability for each TA group while organizing the complexity into manageable segments rather than a monolithic configuration structure.
Solution Approach 2:
The patent introduces a new dimension of organization by associating SRS resource sets with specific TAs, creating a multi-dimensional resource management structure. Instead of managing all SRS resources uniformly, the system adds the TA dimension to the resource organization, allowing independent control and configuration for each TA group, thus improving reliability without proportionally increasing overall complexity.

3Ease of operation
If separate SRS resource sets are used for each Timing Advance, then transmission parameter configuration is improved, but information overhead increases
Solution Approach 1:
The patent implements a unified SRS resource set structure that can serve multiple TAs simultaneously. Each SRS resource set is configured with parameters that can be applied across different TA groups, allowing the same resource set to function universally for multiple timing advances. This reduces the need for completely separate configurations for each TA, thereby improving ease of operation while minimizing the increase in information overhead through shared configuration parameters.

AI summary
The present application discloses a method and a device in a node for wireless communications. A first node transmits a first information block. Herein, the first information block is related to both a first TA and a second TA; the first TA is unequal to the second TA. The method above allows the UE to report information related to different timing advances, thus enabling the base station to configure transmission parameters rationally according to relations among different timing advances, thus enhancing the transmission performance.
