Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, within a subframe, a plurality of sidelink control channel signals providing scheduling information for a plurality of sidelink shared channel signals that are also received within the subframe. The UE may determine to use one or more of the plurality of sidelink control channel signals as pilot signals for decoding the plurality of sidelink shared channel signals. The UE may decode the plurality of sidelink shared channel signals based at least in part on the plurality of sidelink control channel signals as pilot signals.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for flexible selection of a type of mapping to use for mapping code blocks to a set of resources for transmission. A user equipment (UE) may transmit assistance information to a base station to assist the base station in selecting from a set of mapping types available for code block mapping. The UE may then receive, from the base station, an indication of a selected mapping type for code block mapping based on the assistance information. The assistance information may include a recommendation of a mapping type or a metric of a channel that the base station may use to select the mapping type. Because the mapping type may be selected dynamically (e.g., “on the fly”), the UE and the base station may be able to adaptively exploit different types of diversity.

Abstract: Wireless communication techniques for supporting, selecting, and using multiple waveforms and/or multiple decoders for downlink wireless communication are discussed. A UE may transmit to a base station an indication of one or more downlink waveforms or decoders supported by the UE. The UE may also transmit to the base station an indication of power consumption associated with at least one of the one or more downlink waveforms or decoders. The UE may receive from the base station an indication of a waveform or decoder, based on the indication of power consumption, to use for downlink wireless communication.

Abstract: Aspects are provided which allow for a base station to transmit code blocks according to a frequency first per layer (FFPL) mapping, and for a UE to decode received code blocks according to the FFPL mapping. The base station maps a plurality of code blocks to multiple layers, where each of the code blocks is mapped to a plurality of resource elements initially by frequency and subsequently by time on only a single layer of the multiple layers. The base station then transmits data including the code blocks to a UE. Afterwards, the UE receives the data including the mapped code blocks in multiple layers from the base station, and the UE decodes the code blocks based on the mapping. Thus, improvements in link efficiency, reliability, and reduced power consumption compared to frequency first (FF) mapping approaches may be achieved.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a transmitting device, an indication of an instantaneous gain associated with an amplitude distortion associated with frequency division multiplexed downlink communications to the UE from the transmitting device. The UE may receive the frequency division multiplexed downlink communications from the transmitting device over frequency resources allocated to the UE, wherein receiving the frequency division multiplexed downlink communications comprises applying a digital post distortion model to the frequency division multiplexed downlink communications according to the instantaneous gain.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine the subcarrier spacing and carrier frequency used by a user equipment (UE) for communicating with the base station. The base station may select a sounding reference signal (SRS) configuration for the UE that is based on the subcarrier spacing and carrier frequency used by the UE. The SRS configuration may define the temporal spacing between repetitions of the SRS. The base station may indicate the SRS configuration to the UE so that the UE transmits repetitions of the SRS according to the SRS configuration. The base station may measure the SRS repetitions from the UE to determine the Doppler frequency for the uplink channel. The base station may use the uplink Doppler frequency to select a demodulation reference signal (DMRS) configuration for the UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a base station receives one or more signals indicative of a downlink compensation capability (e.g., an in-band capability to compensate for non-linear distortion, or an out-of-band capability to compensate for other FDM'd signal(s) to other UE(s), etc.) of at least one UE. The base station determines a set of downlink transmission requirements based on the downlink compensation capability of the at least one UE, and transmits data to the at least one UE in accordance with the set of downlink transmission requirements.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an indication of a capability for the UE to support narrowband control signaling over a narrowband component carrier that is separate from data channel signaling over one or more wideband component carriers. The UE may receive control signaling indicating a configuration for the narrowband component carrier based on the capability and monitor for the narrowband control signaling on the narrowband component carrier based on the configuration. The UE may perform signal processing on narrowband signaling using a dedicated narrowband receive chain, which may include lower power components than a receive chain for wideband signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit signaling that configures a wireless device to use a multi-level coding (MLC) procedure to communicate with a base station. Based on receiving the signaling, the wireless device may select a channel quality indicator (CQI) index from a set of CQI indices that are associated with an MLC procedure. In some examples, the wireless device selects the CQI index from a set of CQI indices that includes both bit-interleaved coded modulation (BICM)-based and MLC-based CQI indices. In other examples, the wireless device selects the CQI index from a set of CQI indices that includes solely MLC-based CQI indices. The wireless device may transmit the selected CQI index to the base station. And the base station may select a modulation and coding scheme for subsequent transmissions to the wireless device based on the received CQI index.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives control signaling from the base station indicating a set of transmission mode indicators or transmission mode options and a set of demodulation reference signal (DMRS) configurations for every transmission mode from a set of transmission modes. The base station transmits additional control signaling to dynamically indicate a transmission mode or a combination of transmission mode indicators and DMRS configuration parameters to signal the transmission mode and one or more associated DMRS configurations. The UE identifies a DMRS configuration and a transmission mode based on the additional control signaling. The UE receives one or more DMRSs from multiple transmission reception points (TRPs) based on the joint/disjoint DMRS and transmission mode signaling. The UE receives one or more data messages from the TRPs based on the transmission mode indication and based on the received DMRSs.
