Title:
SOUNDING REFERENCE SIGNAL POWER CONTROL FOR MULTIPLE INPUT MULTIPLE OUTPUT WIRELESS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/126361
Kind Code:
A1
Abstract:
A technique includes selecting, by a user device independently for each of a plurality of sounding reference signal resources, an uplink data channel power control parameter set for an uplink data channel beam pair to be used to adjust a sounding reference signal transmission power for a sounding reference signal beam pair, adjusting, by the user device for each sounding reference signal resource based on a selected uplink data channel power control parameter set, asounding reference signal transmission power for a sounding reference signal, and transmitting, by the user device, each of a plurality of power-adjusted sounding reference signals via a corresponding sounding reference signal resource and a corresponding sounding reference signal beam pair.
