Abstract: Systems, apparatuses, and methods for control signaling of beam failure detection are disclosed. A beam pair link may be comprised of multiple bandwidth parts (BWPs) or component carriers (CCs). In one embodiment, a beam failure detection reference signal (BFD RS) may be configured, with subsequent BFD RS instances defining a BFD RS periodicity. A BFD periodicity for monitoring the BFD RS may be configured to be less than, or equal or greater than the BFD RS periodicity. A beam failure may be declared if a minimum number of BFD RS instances, either within the BFD periodicity, or nearest the BFD periodicity if no instances fall within the BFD periodicity, fall below a predetermined threshold. The BFD periodicity and BFD RS may be configured for all BWPs/CCs, a subset of BWPs/CCs, or each individual BWP/CC.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive control signaling to configure transmission of: a first physical uplink control channel (PUCCH) that includes first uplink control information (UCI) of a first UCI type; and a second PUCCH that includes second UCI of a second UCI type. In some cases, if the transmissions of the first PUCCH and the second PUCCH would overlap in a number of slots, the UE may, if the first and second UCI types are not of the same priority: transmit, in the overlapping slots, the PUCCH that includes the UCI type of highest priority; and refrain from transmission in the overlapping slots, and without postponement of the transmission, of the PUCCH that includes the UCI type of lowest priority.

Abstract: A UE can include processing circuitry coupled to memory. To configure the UE for semi-persistent scheduling (SPS) transmission or a grant-free transmission, the processing circuitry is to decode RRC signaling from a base station, the RRC signaling configuring a plurality of transmission configuration information (TCI) candidates indicating a first set of transmission beams for an initial transmission on an SPS PDSCH. The initial transmission uses an initial transmission beam that is selected based on a TCI beam index. A MAC CE from the base station is decoded, the MAC CE indicating a re-configuration of the plurality of TCI candidates to include at least a second set of transmission beams for the SPS PDSCH. A transmission beam is selected from the second set of transmission beams based on the TCI beam index. Downlink data received in a subsequent transmission via the selected transmission beam on the SPS PDSCH is decoded.

Abstract: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications, the processing circuitry is to decode a plurality of CSI-RSs received from a base station on a corresponding plurality of beams. DCI received via a PDCCH is decoded, the DCI activating reporting of beam emissions information associated with the plurality of beams. A CSI report is encoded with the beam emissions information for transmission to the base station, the beam emissions information comprising a flag for each beam of the plurality of beams indicating whether the beam can be used for uplink beam indication. Configuration signaling is decoded with the uplink beam indication, the uplink beam indication based on the beam emissions information and including a CRI of a selected beam of the plurality of beams. Data is encoded for transmission via an uplink channel using the selected beam.

The gNB can encode the time density and the frequency density, for the PT-RS for transmission to the UE in higher layer signaling.
