Multi-Value PHR Reporting for Accurate MPE and Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in reporting maximum permitted exposure (MPE) values for user equipment (UEs) equipped with multiple antenna panels and component carriers, leading to overreporting or underreporting of MPE information, which affects network performance and resource management.
Innovation Solution
A method and apparatus for reporting multiple parameter values in a power headroom report (PHR) that includes specific MPE indications and resource identifiers, allowing for efficient communication by indicating the number of resource IDs and associated P-MPR values, thereby optimizing network resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional PHR reporting methods are used for UEs with multiple antenna panels and component carriers, then the reporting process is simple, but MPE values are inaccurately reported (overreporting or underreporting)
Solution Approach 1:
The PHR is segmented into multiple parts: a first set of parameter values reporting MPE for first component carriers, and a second set of parameter values reporting MPE for second component carriers. This segmentation allows accurate reporting of MPE values for different antenna panels and component carriers separately, resolving the contradiction between reporting accuracy and structure complexity by organizing the complex information in a structured manner.
Solution Approach 2:
The patent introduces a new dimension to the PHR structure by adding a second set of parameter values that were previously not reported. This dimensional expansion allows the system to report MPE values across multiple antenna panels and component carriers simultaneously, achieving comprehensive and accurate MPE reporting without excessive complexity through standardized extension.
2Productivity
If multiple MPE values are reported for different antenna panels and component carriers, then network resource allocation is optimized, but the reporting overhead increases
Solution Approach 1:
The PHR structure is designed with universal applicability to support multiple antenna panels and component carriers using the same reporting mechanism. The first and second sets of parameter values follow a consistent format, allowing the system to report MPE information for various configurations without requiring different reporting structures, thus optimizing network resource allocation while controlling reporting overhead through standardized multi-functionality.
3Reliability
If comprehensive MPE information is reported for all component carriers, then power management is optimized, but unnecessary power reductions occur due to overreporting
Solution Approach 1:
The patent applies local quality by reporting MPE values specific to each antenna panel and component carrier configuration. The first set of parameter values corresponds to first component carriers with their specific MPE characteristics, while the second set corresponds to second component carriers with different MPE characteristics. This localized reporting ensures that power management decisions are based on accurate, configuration-specific MPE information rather than conservative overestimations, preventing unnecessary power reductions while maintaining reliability.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a maximum permitted exposure (MPE) reporting configuration. The UE may transmit, based at least in part on the MPE reporting configuration, a medium access control (MAC) control element (MAC CE) that includes a power headroom report (PHR) corresponding to an activated component carrier, the PHR comprising at least one MPE reporting indication that that indicates at least one MPE value, and at least one additional reporting indication that indicates a number of resource identifiers (IDs) reported in the PHR and a number of additional MPE values reported in the PHR, wherein the additional MPE values are associated with the resource IDs. Numerous other aspects are described.
