Abstract
Methods are disclosed that enable a user equipment (UE) to receive cell specific, UE specific and, in some embodiments, Physical Uplink Shared Channel (PUSCH) specific parameters from a network side component, such as a transmit/receive point, and use that information to set at least one PUSCH transmit power when transmitting to the network side.
Claims20
A method for uplink transmissions, comprising:
- acquiring, by a user equipment (UE), a power parameter specific to a physical uplink shared channel (PUSCH);
- determining, by the UE, a pathloss value for the PUSCH in accordance with a downlink reference signal (DL RS) configuration, the DL RS configuration being associated with a resource index identifying an antenna port;
- deriving, by the UE, a transmission power for the PUSCH in accordance with the power parameter and the pathloss value;
- and
- transmitting, by the UE, the PUSCH on the antenna port at the transmission power.
2 more elements
A device comprising:
- at least one processor;
- a computer-readable medium, having stored thereon computer-executable instructions that, when executed by the at least one processor cause the device to:
- acquire a power parameter specific to a physical uplink shared channel (PUSCH);
- determine a pathloss value for the PUSCH in accordance with a downlink reference signal (DL RS) configuration, the DL RS configuration being associated with a resource index identifying an antenna port;
- derive a transmission power for the PUSCH in accordance with the power parameter and the pathloss value;
- and
- transmit the PUSCH on the antenna port at the transmission power.
