1-32. (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 Base Station (BS) 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 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 Base Station (BS) including one or more power control factors common for a plurality of uplink transmission beams;
- decode, at the UE, higher level signaling received from the base station including one or more offset 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 decoded common power control factor, the offset power control factors for corresponding ones of a plurality of uplink transmission beams, 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 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 Base Station (BS) including one or more power control factors of a plurality of Beam Management Signals (BMS);
- estimate, at the UE, a path loss for corresponding ones of the plurality of Beam Management Signals (BMS);
- determine, at the UE, a kth least path loss (PLkth) for the plurality of Uplink Beam Management Signals (UL BMS);
- and
- determine, at the UE, a transmission power of corresponding ones of the plurality of Uplink Beam Management Signals (UL BMS) as a function of the one or more decoded power control factors and the determined kth least path loss (PLkth) of the Downlink Beam Measurement Reference Signal (DL BM RS);
- 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 Beam Management Signals (UL BMS).
