Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, to each user equipment (UE) of a set of UEs, a different respective set of one or more training parameters for a digital pre-distortion procedure. Some or all of the UEs may determine one or more respective training values based on the one or more training parameters, where the training values from the UEs support the base station computing a set of non-linearity coefficients for the digital pre-distortion procedure. The base station thus may receive training parameters from some or all of the UEs and determine the set of non-linearity coefficients based thereon. The base station use the non-linearity coefficients to perform the digital pre-distortion procedure for one or more downlink transmissions, to one or more UEs of the group of UEs used for training, or to one or more other UEs.

Abstract: Wireless communication techniques that utilize a general purpose (GP) reference signal for non-coherent millimeter-wave communication are discussed. The GP reference signal may have a special structure allowing it to be flexibly used by a mobile device for multiple purposes. A base station may determine a repetition factor for a repetitive intra-symbol GP reference signal mapping based on an event that triggered transmission of the GP reference signal. The base station may also map the GP reference signal to resource elements of a symbol based, at least in part, on the determined repetition factor of the repetitive intra-symbol GP reference signal mapping. The base station may also transmit the mapped GP reference signal. A mobile device may receive the GP reference signal and modify at least one parameter of a plurality of parameters based, at least in part, on processing of the GP reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) transmitting, to a base station, signaling indicating a capability of the UE to utilize a demodulation reference signal (DMRS) for channel state information (CSI) reporting. Upon receiving the signaling, the base station may transmit the DMRS and the UE may update a parameter of a CSI report in response to the received DMRS. The UE may then transmit the CSI report to the base station and the base station may utilize the CSI report for subsequent communications with the UE.

Abstract: An apparatus for wireless communication includes a receiver and a transmitter that is configured to transmit a signal during a first slot. The signal has a power level that is associated with a transmission that is to occur during the first slot or during a second slot after the first slot. The signal is distinct from the transmission. The first slot and the second slot occur during a sub-frame time interval associated with a first cellular vehicle-to-everything (CV2X) wireless communication protocol, and the first slot and the second slot are associated with a second CV2X wireless communication protocol different than the first CV2X wireless communication protocol. The transmitter is further configured to perform the transmission during the second slot based on the power level.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first message indicating a capability of the UE to jointly modulate data with tone reservation signals on an individual subcarrier basis. Accordingly, the UE may receive a second message activating joint modulation of data with tone reservation signals for the UE. In some examples, the UE may also receive control signaling indicating various parameters to use for joint modulation of data with tone reservation signals. The UE may communicate with a base station over multiple subcarriers in accordance with the second message and the control signaling, where one or more of the multiple subcarriers carry data jointly modulated with tone reservation signals on an individual subcarrier basis. The described techniques may enable the UE to perform wireless communications with higher throughput, reduced power consumption, and improved spectral efficiency, among other benefits.

Abstract: The described techniques may support multi-rank sidelink communications that may be reduced to single rank communications if failure to decode the multi-rank sidelink communications occurs. A user equipment (UE) may transmit a first message including first data using a first precoding vector applied for a first layer and a second precoding vector applied for a second layer. If the first message is not decoded successfully, the UE may transmit a second message including second data using a third precoding vector applied for the first layer and a fourth precoding vector applied for the second layer, where the second data is derived from the first data, the third precoding vector is derived from the second precoding vector, and the fourth precoding vector is derived from the first precoding vector. The second message may effectively reduce a rank of the first message when the channel is rank deficient.
