Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing resource block allocation definitions in wireless communication do not facilitate transmission power boost, leading to reduced transmission power due to excessive maximum power reduction (MPR) restrictions, particularly in regions defined by 3GPP specifications.

Innovation Solution

Define more accurate regions for MPR application that enable power boosting in wireless communication devices, independent of channel bandwidth and subcarrier spacing, by using variable parameters based on the number of resource blocks, contiguous allocated blocks, and resource block start, allowing for increased transmission power without significant out-of-channel emissions.

If traditional resource block allocation definitions are used, then regulatory compliance is maintained, but transmission power is reduced due to excessive maximum power reduction restrictions

Core Design Contradiction:

PowerVSReliability

Solution Approach 1:

The frequency spectrum is divided into multiple resource block allocation regions (first region, second region, third region) with different MPR characteristics. This segmentation allows the system to apply different power reduction rules to different frequency regions, enabling power boost in suitable regions while maintaining regulatory compliance in others.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different maximum power reduction values are assigned to different resource block allocation regions based on their spectral characteristics and regulatory requirements. This local differentiation enables optimized power transmission in each region, allowing power boost where permitted while maintaining compliance where restrictions apply.

Core Design Contradiction:

Solution Approach 1:

The MPR values are made dynamic and region-specific rather than uniformly applied. The system dynamically selects appropriate MPR values based on the resource block allocation region, enabling lower MPR (higher power) in regions where spectral emissions are naturally controlled, and higher MPR (lower power) in regions requiring stricter emission control.

AI summary

The present disclosure is directed to techniques to facilitate power boosting for wireless communication devices (e.g., user equipment). The user equipment may be subject to specifications (e.g., the 3GPP specification) that require maximum power reduction (MPR) depending on the resource block allocation region in which the user equipment is operating. However, certain regions defined by the 3GPP specification may not facilitate transmission power boost as applied to shaped (e.g., modulated) transmissions. The techniques disclosed herein include defining the regions such that the MPR restrictions applied to the user equipment are reduced or minimized for allocations that enable power boosting. The regions may be defined using parameters based on a maximum number of resource blocks specified for a certain channel bandwidth, the amount of allocated resource blocks, and the resource block at which the allocation begins.
