Abstract: Aspects herein describe increasing density of reference signal transmissions in wireless communications. A plurality of reference signal configurations, each indicating resource elements for one or more antenna ports over which reference signals for the one or more antenna ports are scheduled for transmission, can be received. An association configuration indicating an association between at least two antenna ports as having similar channel characteristics can also be received. A plurality of reference signals can be received in the resource elements corresponding to the at least two antenna ports as indicated in the at least two of the plurality of reference signal configurations, which can be used to perform a channel measurement of the similar channel characteristics of channels of the at least two antenna ports over at least a portion of the plurality of reference signals.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may receive, at a first location in a downlink signal, preemption information that identifies a second location of a first type of traffic that preempts a second type of traffic, the first location relative to the second location being based at least in part on a hybrid automatic repeat request (HARQ) configuration of the UE. The apparatus may receive the first type of traffic at the second location. The apparatus may generate a HARQ response associated with the first type of traffic. The apparatus may transmit the HARQ response based at least in part on the HARQ configuration of the UE.

Abstract: Methods and apparatus for multiplexing reference signals for Multiple Input Multiple Output (MIMO) layers are provided. Resources for Demodulation Reference Signals (DMRS) corresponding to each of two or more data streams are assigned, wherein the resources assigned to each of the data streams are staggered in frequency and span two or more OFDM (Orthogonal Frequency Divisional Multiplexing) symbols. The DMRS is transmitted using the assigned resources.

Abstract: A communication device receives, from another communication device, a set of transmissions over a sidelink shared channel, or over a downlink shared channel (1005). The communication device estimates a Doppler spread or a delay spread based on the received set of transmissions over the shared channel (1010). The communication device selects a reference signal configuration, from multiple reference signal configurations, based on the estimated Doppler spread or the estimated delay spread (1015). The reference signal is a DMRS, a PTRS and/or a TRS. Finally, the communication device transmits feedback indicating the selected reference signal configuration for a subsequent set of transmissions over the shared channel (1020).

Abstract: Techniques are provided for generating radio frequency (RF) sensing waveforms to enable receiver training in cellular based RF sensing applications. An example method of transmitting a RF sensing signal includes transmitting a first radio frequency signal utilizing a first bandwidth at a first transmit power level, transmitting a second radio frequency signal utilizing a second bandwidth at a second transmit power level, wherein the second bandwidth is larger than the first bandwidth and the second transmit power level is greater than the first transmit power level, and transmitting one or more radio frequency sensing signals utilizing the second bandwidth and the second transmit power level.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a quantity of a first set of symbols for a slot. The UE may receive data in the first set of symbols and a second set of symbols in the slot, wherein the first set of symbols repeat data included in one or more symbols of the second set of symbols. Numerous other aspects are described.

Abstract: In an aspect, a user equipment (UE) may receive at least one discontinuous reception (DRX) configuration, wherein the at least one DRX configuration indicates at least a DRX on-time and a wake-up signal monitoring window for reception of a wake-up signal, wherein the wake-up signal is configured for use in determining whether the UE is to wake-up for sidelink positioning operations. The UE may transition from a sleep state to a wake-up state during the DRX on-time to conduct one or more sidelink positioning operations dependent on whether the wake-up signal is received during the wake-up signal monitoring window.

Abstract: Methods, systems, and devices for wireless communications are described. The techniques described herein may support authentication schemes for wireless communications. A first wireless device may communicate one or more messages associated with an authentication scheme with a second wireless device. The one or more messages may indicate a capability of one or more of the devices, that the authentication scheme includes a symmetric or an asymmetric authentication scheme, or both. The first wireless device may receive a signal from the second wireless device. The signal may include a set of authentication bits. The first wireless device may determine an authenticity of the signal based on the set of authentication bits, the signal, at least one key associated with the authentication scheme, or a combination thereof. The authenticity may indicate whether the signal was sent from the second wireless device or another wireless device.
