Power control of multiple uplink transmissions

A base station (BS) comprising:

• a transceiver configured to:
• transmit configuration information including information related to uplink power control associated with a first set of uplink power control parameters and a second set of the uplink power control parameters, wherein the first set is mapped to a first spatial setting and the second set is mapped to a second spatial setting;
• transmit a downlink control information (DCI) format;
• receive a first physical uplink shared channel (PUSCH) associated with the DCI format;
• and
• receive a second PUSCH associated with the DCI format;
• wherein a first PUSCH transmission power for the first PUSCH is configured based on the first set and the DCI format,
• wherein a second PUSCH transmission power for the second PUSCH is configured based on the second set and the DCI format,
• wherein the first PUSCH transmission power is associated with the first spatial setting,
• wherein the second PUSCH transmission power is associated with the second spatial setting,
• wherein the first set includes a first nominal transmission power related parameter for the first spatial setting, a first downlink pathloss estimate for the first spatial setting, a first weight factor to compensate the first downlink pathloss estimate for the first spatial setting, and a first power control adjustment state for the first spatial setting, and
• wherein the second set includes a second nominal transmission power related parameter for the second spatial setting, a second downlink pathloss estimate for the second spatial setting, a second weight factor to compensate the second downlink pathloss estimate for the second spatial setting, and a second power control adjustment state for the second spatial setting.

A method performed by a user equipment (UE), the method comprising:

• receiving configuration information including information related to uplink power control;
• receiving a downlink control information (DCI) format;
• identifying, based on the information and the DCI format, a first set of uplink power control parameters and a second set of the uplink power control parameters, wherein:
• the first set is mapped to a first spatial setting and the second set is mapped to a second spatial setting,
• the first set includes a first nominal transmission power related parameter for the first spatial setting, a first downlink pathloss estimate for the first spatial setting, a first weight factor to compensate the first downlink pathloss estimate for the first spatial setting, and a first power control adjustment state for the first spatial setting, and
• the second set includes a second nominal transmission power related parameter for the second spatial setting, a second downlink pathloss estimate for the second spatial setting, a second weight factor to compensate the second downlink pathloss estimate for the second spatial setting, and a second power control adjustment state for the second spatial setting;
• identifying, based on the first set, a first physical uplink shared channel (PUSCH) transmission power associated with the first spatial setting;
• transmitting, based on the DCI format, the first PUSCH using the first PUSCH transmission power;
• identifying, based on the second set, a second PUSCH transmission power associated with the second spatial setting;
• and
• transmitting, based on the DCI format, the second PUSCH using the second PUSCH transmission power.
