Abstract: Some embodiments include a processor that receive configuration information from a base station, and store based on the configuration information, a power control (PC) parameter set of a PC process that corresponds to a downlink (DL) reference signal (RS) or a beam-pair link (BPL), where the PC parameter set includes a path loss scaling factor, a command to perform a closed-loop PC process, or a path loss change parameter to be used to trigger a power headroom report (PHR). The processor can perform a PC procedure with respect to the DL RS or the BPL based on the PC parameter set, calculate a path loss estimate based on a downlink reference signal or the BPL, determine the PHR based on the path loss estimate and the path loss change parameter, calculate a power headroom value based on the PC parameter set, and transmit the PHR including the power headroom value.

Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with an Evolved Node-B (eNB) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to process a configuration transmission carrying a half-tone shifting indicator. The second circuitry may be operable to select one or more subcarrier frequencies for Uplink (UL) transmission based on the half-tone shifting indicator. The third circuitry may be operable to generate a UL transmission for the one or more subcarrier frequencies. The half-tone shifting indicator may have a first value indicating application of a half-subcarrier offset, and a second value indicating no application of the half-subcarrier offset.

Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for uplink (UL) beam selection in a New Radio (NR) network, the processing circuitry is to decode a medium access control (MAC) control element (CE) from a base station. The MAC CE identifies a sounding reference signal (SRS) resource set and a plurality of spatial relationship reference signals. An SRS is selected from the SRS resource set. A beam direction associated with a spatial relationship reference signal of the plurality of spatial relationship reference signals is derived. The spatial relationship reference signal corresponds to the selected SRS. The SRS is encoded for beamforming to transmit the selected SRS in the derived beam direction.
