UE Beam Reporting Resource Split for Uplink Conflict Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, there is a conflict in prioritization between user equipment (UE)-initiated beam reporting and uplink transmission procedures, particularly in contention free random access (CFRA), leading to potential communication failures due to unresolved beam conflicts.
Innovation Solution
The UE is configured with two different resource sets for uplink procedures and beam reporting, allowing it to identify concurrent needs and transmit signals based on the best beam and resource sets, either omitting or transmitting beam reports as necessary to resolve conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the UE uses a single resource set for both uplink procedure and beam reporting, then the device complexity is reduced, but communication reliability deteriorates due to unresolved beam conflicts
Solution Approach 1:
The patent divides the uplink resources into two separate resource sets: a first resource set for uplink procedure transmissions and a second resource set for beam reporting transmissions. This segmentation allows the UE to independently manage and prioritize transmissions of different types, resolving beam conflicts without increasing overall system complexity.
2Reliability
If the UE prioritizes uplink procedure transmissions over beam reporting, then uplink transmission reliability is improved, but beam reporting accuracy deteriorates
Solution Approach 1:
By segmenting resources into dedicated sets, the patent ensures that uplink procedure transmissions and beam reporting transmissions do not interfere with each other. Each transmission type has its own dedicated resource set, allowing both to be executed reliably without priority-based trade-offs.
Solution Approach 2:
The patent introduces dynamic priority handling where the UE can switch between different resource sets based on the type of transmission required. The UE determines which resource set to use dynamically based on whether the transmission is for uplink procedure or beam reporting, allowing flexible priority management.
3Measurement precision
If the UE performs beam measurements and reporting continuously, then beam management precision is improved, but energy consumption increases
Solution Approach 1:
The patent configures the UE to perform beam measurements and reporting at specific periodic intervals rather than continuously. The network can configure measurement periods and reporting triggers, allowing the UE to maintain beam management precision while reducing energy consumption by sleeping between measurement periods.

AI summary
According to an aspect, a user equipment may obtain, from a network node, two different resource sets for an uplink signal for an uplink procedure and a user equipment initiated beam reporting procedure. The user equipment may measure beams to determine the best beam. The user equipment may identify a concurrent need to perform an uplink procedure transmission and a user equipment initiated beam report transmission, wherein the identifying comprises a determination whether at least one condition for triggering the user equipment initiated beam report transmission is met. The user equipment may transmit the uplink signal at least in part based on the best beam, the identified need and the two different resource sets.
