Systems, methods, apparatuses, and computer program products for panel specific uplink power control. A method may include receiving, at a user equipment, an uplink grant indicating an uplink candidate beam for uplink transmission; receiving, at the user equipment, a plurality of power control configurations, wherein one of a plurality of sources of spatial relation information is associated with one of the plurality of power control configurations; determining, at the user equipment, a power control configuration of the plurality of power control configurations for the indicated uplink candidate beam based on an association between a source of spatial relation information and the power control configuration; and transmitting, from the user equipment, uplink data using the indicated uplink candidate beam and the determined power control configuration.

Panel specific UL power control

An example method, apparatus, and computer-readable storage medium are provided for panel activation at a user equipment. In an example implementation, the method may include a user equipment (UE) receiving a synchronization signal block (SSB) from a network node; receiving a panel activation request from the network node; measuring a plurality of beams received from the network node; activating one or more panels, the activating based at least on the panel activation request and/or the measuring; and transmitting, by the user equipment (UE): a first transmission of a physical random access channel (PRACH) using a first physical random access channel (PRACH) resource, a second transmission of the physical random access channel (PRACH) using a second physical random access channel (PRACH) resource configured for indicating the activating of one or more panels at the user equipment (UE), and wherein the first transmission and the second transmission are transmitted using a same transmit (Tx) beam from the user equipment (UE).

Panel activation at a user equipment

A method includes determining, by a terminal device, at least one transmission power target level for an intended transmission on at least one sub-band. The method also includes performing a listen before talk procedure and measuring interference, and determining at least one power offset for transmission as outcome of the listen before talk procedure and the measured interference. The method further includes transmitting at least one message on at least one listen before talk allowed sub-band, using a transmission power determined based at least in part on the at least one transmission power target level for the intended transmission on the at least one sub-band, and the at least one power offset.

Adjusting sub-band transmit power based on listen before talk measured interference

Systems, methods, apparatuses, and computer program products for multi-antenna panel transmission power control are provided.
