1-20. (canceled)
An apparatus of a user equipment (UE) operable to configure uplink transmission power in a multi-beam system, the UE comprising:
- one or more processors configured to:
- decode, at the UE, higher level signaling received from a next generation node B (gNB) including one or more power control factors for corresponding ones of a plurality of uplink transmission beams;
- estimate, at the UE, a path loss for corresponding ones of the plurality of uplink transmission beams;
- and
- determine, at the UE, a transmission power of one or more of the plurality of uplink transmission beams as a function of the one or more decoded power control factors and the estimated path loss of the corresponding ones of the plurality of uplink transmission beams;
- and
- a memory interface configured to send to a memory one or more indicators of the determined transmission power of the corresponding ones of the plurality of uplink transmission beams.
An apparatus of a next generation node B (gNB) operable to configure uplink transmission power in a multi-beam system, the apparatus comprising:
- one or more processors configured to:
- determine, at the gNB, one or more power control factors for a plurality of uplink transmission beams;
- and
- encode, at the gNB for transmission to a user equipment (UE), higher level signaling including the one or more power control factors for the plurality of uplink transmission beams;
- and
- a memory interface configured to send to a memory the one or more power control factors.
At least one machine readable storage medium having instructions embodied thereon for a user equipment (UE) configured for uplink transmission power in a multi-beam system, the instructions when executed by one or more processors at the UE perform the following:
- decoding, at the UE, higher level signaling received from a next generation node B (gNB) including one or more power control factors for corresponding ones of a plurality of uplink transmission beams;
- estimating, at the UE, a path loss for corresponding ones of the plurality of uplink transmission beams;
- and
- determining, at the UE, a transmission power of one or more of the plurality of uplink transmission beams as a function of the one or more decoded power control factors and the estimated path loss of the corresponding ones of the plurality of uplink transmission beams.
