Abstract

A wireless device receives configuration parameters of a cell that comprise: first parameters indicating: configuration of SRSs of the cell; whether a first accumulated power control adjustment for the SRSs is enabled; and second parameters. The second parameters indicate: configuration of an uplink data channel of the cell; and whether a second accumulated power control adjustment for the uplink data channel is enabled. A first transmission power is determined for the SRSs based on the first accumulated power control adjustment and a first power control command. The SRSs are transmitted, via the cell, with the first transmission power. A second transmission power is determined for the uplink data channel of the cell based on the second accumulated power control adjustment and a second power control command. One or more transport blocks are transmitted, via the uplink data channel of the cell, with the second transmission power.

Claims19

Dependent claims

A method comprising:

receiving, by a wireless device from a base station, a downlink control information (DCI) indicating a sounding reference signal (SRS) transmission via a first slot of a cell;
determining a first transmission power for the SRS transmission via the first slot, based on a first power control command received a first number of symbols before the first slot, the first number of symbols being determined based on the DCI;
transmitting, by the wireless device and via the first slot of the cell, the SRS with the first transmission power;
determining a second transmission power for an uplink data channel transmission via the cell at a second slot, wherein the second transmission power is based on a second power control command received a second number of symbols before the second slot, wherein the second number is determined based on a numerology of the uplink data channel;
and
transmitting, by the wireless device and via the uplink data channel of the cell, a transport block with the second transmission power.
