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 Long Term Evolution Advanced (LTE-A) location server, user equipment (UE) and evolved Node-B (eNB) are generally described. Information may be transmitted to the UE from the location server. The transmission may be triggered by the location server or another entity requesting the UE location. The information may permit the UE to receive a discovery reference signal (DRS) from at least one eNB. The information may contain an indication of measurements to be performed using the DRS. The UE may measure Reference Signal Received Power (RSRP) or Reference Signal Time Difference (RSTD) of the DRS. The UE may send the measurement information to the location server where the UE location is estimated. The UE location may be based on measurements of the DRS and a positioning reference signal (PRS) from one or more eNBs to obtain the Observed Time Difference of Arrival (OTDOA) or Enhanced Cell ID (ECID).

Abstract: Technology is discussed for extending frequency and time based approaches, such as Inter-Cell Interference Coordination (ICIC) and enhanced ICIC (eICIC), to interference mitigation for clusters within a Wireless Wide Area Network (WWAN) of transmission points with a common transmission point identity. Multiple transmission power messages correlated to different transmission point characteristics can be configured among multiple transmission points sharing the same transmission point identity. These multiple transmission power messages can be used to coordinate transmissions from adjacent transmission points on differing frequencies. Additionally, new sets of reference signals can be configured to correlate to different transmission point characteristics. These new, correlated reference signals can be used to decouple measurements used to provide feedback to one set of transmission points from reference signals transmitted by another set of transmission points with the same transmission point identity.
