Abstract
There is a method comprising determining a beamforming configuration for a time period for reception of uplink data from a user device, determining uplink power control information based on the determined beamforming configuration and providing an indication of the determined uplink power control information to the user device for use in determining uplink transmit power for the time period.
Claims15
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program instructions, the at least one memory and the computer program instructions configured to, with the at least one processor, cause the apparatus at least to:
- receive, from a network node, downlink control information including an indication indicative of uplink power control information to be used by the apparatus,
- wherein the uplink power control information is determined based on a beamforming configuration for a time period intended for transmission of uplink data,
- the uplink power control information comprises an indication of a set of power control parameters from a plurality of sets of power control parameters,
- the indicated set of power control parameters is associated with the beamforming configuration used for a measurement related to a pathloss, and
- each of the plurality of sets of power control parameters comprises at least a P0 and an alpha parameters;
- determine the pathloss based on the beamforming configuration associated with the indicated set of power control parameters;
- and
- transmit the uplink data during the time period by using uplink transmit power determined based on the indicated set of power control parameters and the determined pathloss.
