Abstract: The apparatus may be a device at a UE or a base station. The UE (or base station) may be configured to measure a phase noise of a first local oscillator associated with a first port. The UE (or base station) may further be configured to configure, based on the measured phase noise, an allocation of a first set of one or more REs of a PUSCH (or PDSCH) for at least one PT-RS associated with the first port. The first set of one or more REs may include multiple layers associated with a multiple-layer single-carrier waveform transmission. The UE (or base station) may also be configured to transmit, to a base station (or a UE), the PUSCH (or PDSCH) including the at least one PT-RS, the at least one PT-RS being transmitted via the configured allocation of the first set of one.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting device may generate a frequency-domain-multiplexed signal by performing frequency domain multiplexing of a data signal and a reference signal within a symbol of a discrete Fourier transform spread orthogonal frequency domain multiplexing waveform communication, the reference signal being one of a demodulation reference signal, a sounding reference signal, or a channel state information reference signal. The transmitting device may transmit, to a receiving device, the frequency-domain-multiplexed signal. Numerous other aspects are described.

Abstract: In an aspect, an OWC transmitter transmits, to an OWC receiver, a first DC bias parameter, receives, from the OWC receiver, DC bias feedback based on a measurement associated with an OWC link between the OWC transmitter and the OWC receiver, and transmits an OWC signal with a second DC bias parameter that is based on the DC bias feedback from the OWC receiver. In another aspect, an OWC receiver receives, from an OWC transmitter, a first DC bias parameter, transmits DC bias feedback based on a measurement associated with an OWC link between the OWC transmitter and the OWC receiver, and receives, from the OWC transmitter, an OWC signal having a second DC bias parameter based on the DC bias feedback.

Abstract: An apparatus may be configured to transmit (or receive) an indication of a first DMRS, where the first DMRS is identified based on at least two of a non-linearity of a power amplifier of the first device, a modulation and coding scheme (MCS) used for a data transmission associated with the first DMRS, or a channel type of a channel associated with the first DMRS; transmit (or receive), for a second device (or from a first device), the first DMRS for channel estimation at the second device; and transmit (or receive) the data transmission associated with the first DMRS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may apply an orthogonal time frequency space (OTFS) precoding to a plurality of tracking reference signal (TRS) resource samples allocated in a delay-Doppler domain to obtain a plurality of TRS symbols with the OTFS precoding. The first network node may transmit, to a second network node, a TRS in which the plurality of TRS symbols with the OTFS precoding have a uniform spacing in a time domain. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for time division multiplexing (TDMing) user equipment (UE) data using guard interval (GI)-based waveforms. An example method generally includes communicating with a device using a frame format, the frame format comprising a first symbol, a second symbol, and a third symbol, wherein: the first symbol comprises a first data portion for a first UE and a first GI corresponding to the first UE; the third symbol comprises a second data portion for a second UE and a second GI corresponding to the second UE, wherein the third symbol is later in time than the first symbol; and the second symbol comprises a gap or a reference signal (RS), a third GI corresponding to the first UE, and a fourth GI corresponding to the second UE, wherein the second symbol is between the first and third symbol in time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may precode a sounding reference signal (SRS) transmission using a delay-Doppler precoder. The UE may transmit, after precoding the SRS transmission using the delay-Doppler precoder, the SRS transmission in an SRS symbol in a slot. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless device determines a symbol configuration for transmission of SC-FDE waveform with zero gaps arranged between a communication channel part, RS part, and CP part. The SC-FDE waveform is transmitted to another wireless device, which processes the SC-FDE waveform.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive, from a first wireless device, an uplink communication using a first guard interval. The IAB may receive, from a second wireless device, a downlink communication using a second guard interval, a second length of the second guard interval being different from a first length of the first guard interval. The IAB may process the uplink communication and the downlink communication in a same fast Fourier transform window. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) transmitted using a single carrier quadrature amplitude modulation (SC-QAM) waveform, wherein the SSB has a uniform bandwidth allocation for each of a primary synchronization signal (PSS) included in the SSB, a secondary synchronization signal (SSS) included in the SSB, and physical broadcast channel (PBCH) data included in the SSB. The UE may perform initial channel access based at least in part on the SSB. Numerous other aspects are described.
