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: 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: 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.

Abstract: Wireless communications systems and methods related to hybrid in-band same-frequency full-duplex (SFFD) and frequency-offset-frequency full-duplex (FD) wireless communication are provided. A user equipment (UE) transmits first data to a base station (BS) over a first frequency band while receiving second data from the BS the first frequency band responsive to a first pathloss between the UE and the BS satisfying a threshold for an SFFD operation. The UE transmits third data to the BS over a second frequency band while receiving fourth data from the BS over a third frequency band that is distinct from the second frequency band according to an offset-frequency FD operation responsive to a second pathloss between the UE and the BS failing to satisfying the threshold.

Abstract: Methods, systems, and devices for wireless communications are described that support a single carrier multi-level coding (MLC) amplitude phase shift keying (APSK) modulated waveform. For example, a user equipment (UE) capable to communicate using MLC APSK modulated waveforms may transmit a channel state information (CSI) report, including a recommendation for a waveform configuration, to a base station. The base station may receive the CSI report and may transmit a configuration message to the UE, which may configure the UE with a set of waveform parameters associated with MLC APSK modulation. The UE may receive the configuration message and may communicate with the base station using MLC APSK modulated waveforms and based on the set of waveform parameters, which may reduce phase noise and provide lower peak average power ratio (PAPR) signaling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit a request, for an uplink transmission or a downlink transmission, for data aided phase tracking reference signals (PT-RSs); and communicate the uplink transmission or the downlink transmission based at least in part on the request. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a control message indicating a capability of the UE to identify and report a reciprocity parameter between downlink communications and uplink communications of a channel between the UE and the base station. In some examples, the base station may request a reciprocity report from the UE. The UE may identify a reciprocity parameter based on one or more parameters associated with an array of antennas at the UE. The reciprocity parameter may indicate a reciprocity between an uplink beam and a downlink beam, such as a degree of overlap between the uplink beam and the downlink beam. The UE may report the reciprocity parameter via a reciprocity report to the base station. In some examples, the base station may identify one or more parameters based on the reciprocity report.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) and a base station implement reference signal modulation for conveying feedback information. In some examples, the UE may receive, from the base station, control signaling indicating to the UE to convey feedback information by modulating an uplink reference signal. The UE may receive, from the base station, a set of downlink messages. In some cases, the UE may transmit, to the base station, a set of uplink reference signals in response to receiving the downlink messages, where the set of uplink reference signals may be modulated by the UE to convey the feedback information. In some cases, the uplink reference signal may be a sounding reference signal (SRS) with embedded feedback information.
