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: An apparatus for a terminal has means for storing a first configuration for measurement reporting on downlink reference signals, wherein one or more downlink reference signals correspond to one of a plurality of states for a first channel. The apparatus also has means for receiving an activation of a first state of the plurality of states for the first channel, and determining a second configuration for measurement reporting based on the first configuration for measurement reporting and the received activation of the first state, wherein the second configuration for measurement reporting configures the terminal to report measurements on a first downlink reference signal corresponding to the first state.

Abstract: A UE, communicating with a network node by using TDD, determines a downlink/uplink configuration between the UE and the network node, and a maximum uplink duty cycle for candidate uplink transmit beam(s). The UE compares the maximum uplink duty cycle with an uplink duty cycle of the determined downlink/uplink configuration, and provides to the network node information associated with the comparison. The network node receives the information associated with the comparison and determines whether to modify the downlink/uplink configuration between the user equipment and the network node based on the information associated with the comparison. The network node indicates, in response to a determination the downlink/uplink configuration should be modified, a modified downlink/uplink configuration to the user equipment.

Abstract: Method, apparatus, and computer program product for a CORESET beam recovery procedure and a QCL association beam recovery procedure where a condition or rule based UE initiated change of active TCI state is used. The CORESET beam recovery procedure involves a downlink reference signal corresponding to a transmission configuration indication state activated for certain CORESET being determined as a beam failure detection resource. The QCL association beam recovery procedure concerns a UE transmitting a UL request signal to require switching an active TCI state of the CORESET to a currently deactivated TCI state of the same CORESET.
