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.
Claims18
A method comprising:
- determining, by a network node, a plurality of beamforming configurations to be used for measurements related to pathloss;
- determining, by the network node, a plurality of sets of uplink power control parameters based on the determined plurality of beamforming configurations;
- and
- providing, by the network node, downlink control information including an indication indicative of a set of uplink power control parameters from the plurality of sets of uplink power control parameters to a user device;
- wherein the set of uplink power control parameters is linked with one of the plurality of beamforming configurations;
- and
- wherein each of the plurality of sets of uplink power control parameters comprises at least a P0 and an alpha parameters.
