Joint MPE Reporting for Single- and Multi-Panel UL Transmissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack effective methods for reporting maximum permissible exposure (MPE) values for both single-transmission and multi-panel/simultaneous transmissions, leading to incomplete network awareness of MPE values and inefficient resource utilization.
Innovation Solution
Implementing a system that enables user equipment (UE) to jointly report MPE values for single-transmission and multi-panel/simultaneous transmissions by configuring MPE resource pools and utilizing power headroom reports (PHRs) to provide MPE indications for multiple sounding reference signal (SRS) resource sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate reporting methods are used for single-transmission and multi-panel MPE values, then reporting completeness is improved, but signaling overhead and complexity increase
Solution Approach 1:
The patent combines separate MPE value reports for single-transmission and multi-panel transmissions into a single joint Power Headroom Report (PHR) message. This merging approach transmits both MPE values simultaneously, reducing signaling overhead and reporting complexity while ensuring complete MPE value reporting for both transmission types.
2Loss of information
If joint MPE reporting is implemented, then network awareness is improved, but processing complexity increases
Solution Approach 1:
The joint PHR message structure is designed to universally carry both single-transmission MPE values and multi-panel MPE values. This multi-functional reporting mechanism enhances network awareness of MPE values for different transmission types while managing processing complexity through a unified reporting framework.
3Adaptability or versatility
If multiple MPE resource pools are configured, then resource allocation flexibility is improved, but configuration complexity increases
Solution Approach 1:
The patent segments MPE resource pools into distinct configurations, allowing separate management of resources for single-transmission and multi-panel transmissions. This segmentation provides resource allocation flexibility while controlling configuration complexity through structured resource pool definitions.

AI summary
A UE receives, from a network node, a configuration for two uplink (UL) transmissions on a component carrier (CC); and transmits, to the network node and in response to at least one power headroom report (PHR) transmission condition, an indication that corresponds to two maximum permissible exposure (MPE) values associated with at least two sounding reference signal (SRS) resource sets, respectively, for the one or more simultaneous UL transmissions on the CC. The UE receives, from a network node, a configuration for a set of MPE indication parameters that is associated with a first MPE resource pool and a second MPE resource pool at the UE; and transmits, to the network node, an indication of values for the set of MPE indication parameters associated with the first MPE resource pool and the second MPE resource pool.
