    Abstract: User equipment (UE) positioning within a 5G New Radio (NR) network may be determined by receiving a downlink (DL) position reference signal (PRS) resource set indicating a plurality of DL PRS resources and receiving a DL PRS report configuration that indicates a set of measurements to be performed by a UE for each of the plurality of DL PRS resources within the DL PRS resource set. Position measurements may be performed for each of the plurality of DL PRS resources within the DL PRS resource set, including generating a reference signal time difference (RSTD) measurement by estimating a timing of a first arrival path from at least two of the plurality of DL PRS resources and determining a reference signal received power (RSRP) metric or a signal to noise and interference ratio (SINR) metric associated with the at least two DL PRS resources. The performed position measurements may be reported.

    Abstract: A device of a New Radio (NR) User Equipment (UE), a system, a method and a machine-readable medium. The device includes a radio frequency (RF) interface, and a processing circuitry coupled to the RF interface, the processing circuitry to: decode a message from a NR Node B (gNodeB), the message corresponding to a unicast message or to a broadcast message and being received through a Universal Mobile Telecommunications System (UMTS) interface (Uu interface), the message further including reference time information; and determine a reference time from the reference time information, the reference time to be used by higher layers of the UE.

    Abstract: In one embodiment, an apparatus includes memory storing instructions and processing circuitry coupled to the memory. The processing circuitry is to implement the instructions to select a resource block group (RBG) size configuration from a set of RBG size configurations based on a bandwidth part (BWP) size. Each RBG size configuration is to indicate RBG sizes associated with respective ranges of BWP sizes, and the RBG sizes are to indicate a number of frequency-domain physical resource blocks (PRBs) for physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) transmissions. The processing circuitry is further to implement the instructions to allocate PRBs for communication between the gNB device and a user equipment (UE) device via the PDSCH or PUSCH transmissions based on the selected RBG size, and to encode downlink control information (DCI) that indicates the allocated PRBs for transmission to the UE device.
