Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive an information element (IE) that includes: a higher layer parameter that indicates a plurality of modulation and coding scheme (MCS) thresholds; and another higher layer parameter that includes a plurality of resource block (RB) thresholds. The UE may determine a time density of phase tracking reference signal (PT-RS) to be transmitted by the UE based at least partly on a comparison between a MCS and the plurality of MCS thresholds. The UE may determine a frequency density of the PT-RS based at least partly on a comparison between a scheduled bandwidth and the plurality of RB thresholds. The UE may encode the PT-RS for transmission in accordance with the determined time density and the determined frequency density.

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.

The method may include determining that a first CSI report and a second CSI report are to be sent in the PUCCH, where the first CSI report has a first reporting type and a first CSI sub-frame set, and the second CSI report has a second reporting type and a second CSI sub-frame set. The method may include determining to drop the first CSI report if the first CSI sub-frame set has a second lower priority than the second CSI sub-frame set. The determination to drop may be further based on a CSI processor index, serving cell index, and the CSI report priority.

In one embodiment, for example, an evolved node B (eNB) may comprise a processor circuit, a communication component for execution by the processor circuit to receive a channel quality index for a physical downlink shared channel (PDSCH), the channel quality index associated with a defined reference resource, and a selection component for execution by the processor circuit to select a modulation and coding scheme (MCS) for transmission over the PDSCH of user equipment (UE) data in one or more resource blocks, the selection component to compensate for a difference between a cell-specific reference signal (CRS) overhead of the defined reference resource and a CRS overhead of the one or more resource blocks when selecting the MCS. Other embodiments are described and claimed.
