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.

Abstract: Aspects of the present disclosure provide techniques for using cyclic-shifts in code division multiplexing to shift transmitted signals (e.g., reference signals, control signals, and/or data) from different antenna ports of the transmitting device. Particularly, for multiple-input multiple-output (MIMO) systems that multiply the capacity of a radio link by using multiple transmit and receive antennas to exploit multipath propagation, aspects of the present disclosure minimize interference at the receiving device by separating the signals from different antenna ports based on the channel impulse response (or delay spread) of each antenna port of the channel. In some examples, the transmitting device may maximize resource utilization by interleaving the reference signals, control signals, and/or data from a plurality of antenna ports while maintaining adequate spacing between each signal.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that adapts a numerology including a subcarrier spacing and/or cyclic prefix for a user equipment (UE) traveling at a high speed. A base station may transmit via a plurality of remote radio heads (RRH) to a user equipment (UE) is moving along a high speed track. The base station may transmit, in a first time period, using a first numerology including a first subcarrier spacing and a first cyclic prefix ratio, a first transmission for the UE. The base station may transmit, in a subsequent time period, using a second numerology including a second subcarrier spacing and a second cyclic prefix ratio, a second transmission for the UE. At least one of the second subcarrier spacing is different than the first subcarrier spacing or the second cyclic prefix ratio is different than the first cyclic prefix ratio.

Abstract: Aspects of the present disclosure provide methods and apparatuses for sounding reference signal (SRS) enhancements. An exemplary method performed by a user equipment generally includes receiving information indicating a symbol, in a sub-frame of a radio frame used to communicate in the wireless network, for transmission of sounding reference signals (SRSs), wherein a location of the symbol in the sub-frame is based, at least in part, on a location of the UE and transmitting a SRS in the symbol based on the received information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a channel state information (CSI) report that is associated with a multi-symbol downlink reference signal and that indicates a report quantity associated with a Doppler shift measurement, a per-path Doppler measurement, or a per-beam-per-path Doppler measurement. The UE may count a number of CSI processing units (CPU's) for processing the CSI report based at least in part on the report quantity. Numerous other aspects are described.

Abstract: Method and apparatus for reporting of time domain channel characteristics. The apparatus receives a Doppler configuration to measure Doppler information for at least one channel path of a plurality of channel paths. The apparatus receives a tracking reference signal (TRS) to obtain the Doppler information for the at least one channel path of the plurality of channel paths based on the Doppler configuration. The apparatus transmits a Doppler report comprising the Doppler information for the at least one channel path of the plurality of channel paths based on the received TRS. The apparatus receives a downlink transmission on a predicted channel and precoder, the predicted channel and the precoder based at least on the Doppler report.

Abstract: Aspects relate to power boosting for concurrent decoding and energy harvesting. A wireless communication device may receive a power boosting parameter indicating a power boosting amount for energy harvesting. The wireless communication device may further receive a first portion of a transmission at a first power and a second portion of a transmission at a second power higher than the first power. The wireless communication device may concurrently decode and harvest energy from the second portion of the transmission using a power splitting factor based on the power boosting parameter. Aspects further relate to indicating slots for energy harvesting. For example, a wireless communication device may receive a slot including control information that is located within a control resource set or scrambled with a radio network temporary identifier indicating a slot type of the slot.
