Abstract: An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for 5G-NR communications, the processing circuitry is to decode higher layer signaling received from a base station, the higher layer signaling to configure a plurality of BWPs for UL and DL communication with the base station. A received DCI includes a field triggering SRS reporting. The field also indicates a subset of the plurality of BWPs for the SRS reporting. SRS is encoded for transmission to the base station using a first BWP of the subset of the plurality of BWPs indicated by the field to perform the SRS reporting. An UL communication comprising a PUSCH is encoded for transmission using a second BWP of the plurality of BWPs, the second BWP being non-overlapping with the subset of the plurality of BWPs.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for selecting a TCI-State for receiving downlink transmissions. In one example a processor/UE is configured to determine one or more candidate TCIs for a downlink slot; determine a scheduling offset between a physical downlink shared channel (PDSCH) and a physical downlink control channel (PDCCH); prioritize the candidate TCIs based on the scheduling offset; identify a highest priority candidate TCI; and select the highest priority candidate TCI for receiving the PDSCH.

Abstract: A generation node B (gNB) configured for aperiodic channel state information reference signal (CSI-RS) triggering and transmission may encode signalling for transmission to a user equipment (UE). The signalling to indicate an aperiodic Triggering Offset (aperiodicTriggeringOffset). The aperiodic Triggering Offset may comprise a slot offset. The gNB may encode a downlink control information (DCI) for transmission that may trigger transmission of a CSI-RS in one or more aperiodic CSI-RS resource set(s) (i.e., in one or more slots (n)). The DCI triggers transmission of the aperiodic CSI-RS within a triggered slot with the slot offset (i.e., the aperiodicTriggeringOffset). The gNB may transmit the CSI-RS in resource elements of the triggered slot in accordance with the slot offset, when CSI-RS resources are available in the slot at the slot offset. The gNB may postpone transmission of the aperiodically triggered CSI-RS to a first available downlink slot when the CSI-RS resources are not available in the triggered slot at the slot offset.

Abstract: A method for rescheduling a resource component of low power nodes (LPNs) in a local coordination set is disclosed. The method can include a local macro node receiving from a neighboring macro node a resource map of blanked resource components and scheduled resource components for physical resources of the neighboring macro node. The local macro node can be grouped with at least one low power node (LPN) within a local coordination set. The neighboring macro node can be grouped with at least one LPN within a neighboring coordination set. The neighboring macro node can be within a neighboring coordination set different from the local coordination set. The local macro node can reschedule using the resource map, a cell-edge resource component for LPNs in the local coordination set in a same frequency-domain index and a same time-domain index as a blanked resource component of the neighboring macro node.
