Abstract: Signaling is received (or transmitted) to configure a UE with multiple transmit beams, each for receiving beam-specific DCI. A beam-specific current DCI is received at the UE (or transmitted from a network) on the transmit beam(s), including information about beam-specific previous DCIs transmitted to the UE on any of the multiple transmit beams within a predefined time window preceding a time unit in which the current DCI was received. Information about the beam-specific previous DCIs is used to determine that at least one of the multiple transmit beams has been blocked. Each of the multiple transmit beams that have been determined to be blocked is reported to (and received by) the network. In response to receiving from the UE a report indicating at least one multiple transmit beams has been blocked, the network reconfigures the UE with a different set of multiple transmit beams each for beam-specific DCI.

Abstract: 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.
