Abstract: In an embodiment, a cell punctures resource(s) allocated to transmission of UL or DL PRS(s). The cell communicates (e.g., receives or transmits) UL or DL higher-priority signal(s) on the punctured resource(s), and communicates the UL or DL PRS(s) on the non-punctured resource(s). In another embodiment, a second cell neighboring a first cell schedules and transmits the UL or DL higher-priority signal(s) on part of the first cell's PRS resource(s). In another embodiment, the first cell receives an indication of the UL or DL higher-priority signal(s) scheduled for transmission by the second cell, and punctures its PRS resource(s) to reduce interference on the second cell's UL or DL higher-priority signal(s). In a further embodiment, a UE receives an indication of puncturing and selectively modifies its PRS processing on the punctured resource(s).

Abstract: Disclosed are techniques for transmitting reference signals (RS) for positioning. A method comprises transmitting or providing an instruction to transmit a first set of RS to a user equipment (UE) in accordance with a first set of RS transmission parameters, receiving a report containing information indicating whether a measurement performed by the UE is limited by a signal-to-noise ratio (SNR) of the first set of RS or a bandwidth of the first set of RS, determining a second set of RS transmission parameters using the received report, wherein the second set of RS transmission parameters is different from the first set of RS transmission parameters, and transmitting a second set of RS to the UE in accordance with the second set of RS transmission parameters, or providing the second set of RS transmission parameters to a base station.

Abstract: Disclosed are techniques for receive beam selection for measuring a reference radio frequency (RF) signal. In an aspect, a first node determines a type of measurement to be performed on the reference RF signal, selects a receive beam based on the type of measurement to be performed on the reference RF signal, generates the selected receive beam, receives, from a second node, using the generated receive beam, the reference RF signal transmitted on a wireless channel, and performs one or more measurements on the received reference RF signal according to the type of the measurement to be performed.

Abstract: Aspects of the disclosure relate to a configurable demodulation reference signal (DMRS) when utilizing a fallback downlink control information (DCI) format that lacks DMRS antenna port information or DMRS sequence initialization information. The DMRS configuration may be identified based on one or more semi-static and/or dynamic parameters, such as a cell identifier, cell radio network temporary identifier, DMRS scrambling identifier, subframe number and/or slot index.

Abstract: Aspects of the present disclosure provide techniques for handling power transitions in transmissions in new radio (NR) devices. An exemplary method includes changing from using a first transmit power during a first portion of a transmission to a second transmit power during a second portion of the transmission, and taking action to mitigate a potential phase coherence loss associated with the changing from the first transmit power to the second transmit power.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing channel state information (CSI) reference signals (CSI-RSs) and synchronization signals in wireless communications systems operating according to new radio (NR), e.g., 5th generation (5G), techniques. An exemplary method includes sampling subcarriers of a synchronization signal (SS) block based on a frequency density of channel state information (CSI) reference signals (CSI-RSs) multiplexed in a symbol period with the SS block, and performing at least one of: measuring at least one of reference signal received power (RSRP) or CSI, based on the sampled subcarriers and the CSI-RSs, or reporting at least one of the RSRP or the CSI, based on the sampled subcarriers and the CSI-RSs.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus maybe a base station or a UE. In an aspect, the apparatus may determine locations for a number of DM-RS symbols to be transmitted in a scheduling unit of a channel configured in a slot/mini-slot, where a last DM-RS symbol maybe positioned one symbol prior to a last symbol carrying scheduled data. In another aspect, the apparatus may determine the locations for the DM-RS symbols based on a selection between a first set of predetermined DM-RS positions and a second set of predetermined DM-RS positions. In another aspect, the apparatus may determine the locations for the DM-RS symbols based on a set number of symbols, wherein the determined locations are spaced apart according to the set number of symbols. The apparatus may transmit the DM-RS symbols based on the determined locations.

Abstract: Aspects herein describe transmitting a reference signal in wireless communications. A configured delay value related to a delay in communications can be determined based on receiving a corresponding resource grant. A time division of a slot for transmitting a reference signal for the communications can be determined based at least in part on the configured delay value. The reference signal can be transmitted during the time division of the slot.
