Terminal Transmit Power Configuration via FR1-FR2 Parameter Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems, particularly in those supporting Frequency Range 2 (FR2), the existing configuration of transmit power based on P-max values from Frequency Range 1 (FR1) is inadequate, as the range of possible values for FR2 cannot be covered by the P-max values specified for FR1, leading to inappropriate power configuration and potential interference issues.
Innovation Solution
The solution involves associating P-max values from FR1 with corresponding transmit power information in FR2, using a correspondence relationship that adjusts the granularity of P-max values in FR2 based on specific ranges and boundary values, allowing for a finer configuration of transmit power in FR2 to match the demands of different frequency bands.

Engineering Contradiction Analysis
1Adaptability or versatility
If P-max values from FR1 are used for FR2, then existing base stations and terminals can be supported without changes, but the range of possible values for FR2 cannot be covered leading to inappropriate power configuration
Solution Approach 1:
The patent introduces P-relation information as an intermediary element that maps FR1 P-max values to FR2 transmit power values. This intermediary allows the system to maintain compatibility with existing FR1 configurations while enabling appropriate power settings for FR2 by establishing a correspondence relationship between the two frequency ranges.
Solution Approach 2:
The patent changes the parameter representation by introducing P-relation information that transforms FR1 P-max values into corresponding FR2 transmit power values. This parameter transformation allows the system to use existing FR1 power configurations as a basis while adapting them to FR2 requirements through defined correspondence relationships.
2Manufacturing precision
If the granularity of P-max values in FR2 is increased for finer configuration, then transmit power can be appropriately configured for different frequency bands, but the complexity of power configuration increases
Solution Approach 1:
The patent performs preliminary action by pre-defining correspondence relationships between FR1 P-max values and FR2 transmit power values through P-relation information. This preliminary configuration allows the system to handle complex FR2 power requirements without real-time calculation complexity, as the mappings are established in advance.
Solution Approach 2:
The patent manages configuration complexity by changing the parameter representation through P-relation information, which transforms detailed FR2 power requirements into manageable mappings from FR1 P-max values. This parameter transformation approach allows fine-grained control without directly managing the full complexity of FR2 power configurations.
