US 11,690,022 B2 · Managing transmit power control

Abstract

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing transmit power control. In one aspect, a wireless device may receive a message including a path loss value and may transmit a signal to a UL Rx point using an uplink transmit power associated with the received path loss value. In another aspect, a wireless device may receive a reference signal, and a message including an offset value, and may transmit a signal to a UL Rx point using an uplink transmit power including a downlink path loss value associated with the reference signal minus the offset value. In another aspect, a base station may obtain a power measurement of a signal from a wireless device and may send to the wireless device a path loss value associated with the received power measurement, or an offset value associated with the received power measurement.

Dependent claims

A method performed by an apparatus of a wireless device for managing transmit power control, comprising:

receiving from a base station a message including a path loss value comprising a physical uplink control channel (PUCCH) path loss value or a sounding reference signal (SRS) path loss value;
and
transmitting a PUCCH or SRS signal to an uplink (UL) receive (Rx) point that is different from the base station using an adjusted uplink transmit power associated with the received respective PUCCH path loss value or SRS path loss value.

Dependencies are inferred from the claim text.
