Beam-Aware Uplink Power Control for 5G NR WTRUs

The patent applies local quality by assigning different maximum power level parameters to different transmission beams based on their angular separation. When beams are separated by less than a threshold angle, a first maximum power level parameter is applied; when separated by more than the threshold, a second maximum power level parameter is applied. This localized differentiation ensures EIRP and TRP compliance while maintaining manageable complexity through clear angular-based decision logic.

The patent applies parameter changes by using numerology parameters (such as subcarrier spacing) and beam properties (such as angular separation and beam direction) as criteria for determining power scaling priority. Different numerologies and beam configurations trigger different power scaling treatments, allowing the system to maintain transmission reliability through parameter-driven decision making rather than complex algorithms.

The patent applies self-service by enabling the WTRU to autonomously determine which maximum power level parameter to apply based on angular separation measurements and configured thresholds. The device automatically performs power control decisions without requiring manual intervention or complex user configuration, maintaining regulatory compliance while preserving ease of operation through automated decision logic.
