Abstract: Aspects are provided for generation and transmission of MDMRS which allow matching of nonlinear model impact or properties between DMRS and data in DFT-s-OFDM waveforms as well as CP-OFDM waveforms. A UE transmits, to a network entity, an MDMRS generated from a DMRS. The MDMRS has a PAPR distribution matching a PAPR distribution of a signal including data in an uplink channel. A target PAPR of the MDMRS is based on a modulation scheme of the data. The UE also transmits the data in the uplink channel, where the uplink channel includes a PUCCH or a PUSCH. As a result of the ability of MDMRS to match the nonlinear impact of DMRS and PUSCH or PUCCH, the network entity may compensate for any EVM that may occur as a result of PAPR reduction by a nonlinear operator of the UE, and communication performance may thereby be improved.

Abstract: Various aspects of the present disclosure generally relate to neural network based channel state information (CSI) feedback. In some aspects, a device may obtain a CSI instance for a channel, determine a neural network model including a CSI encoder and a CSI decoder, and train the neural network model based at least in part on encoding the CSI instance into encoded CSI, decoding the encoded CSI into decoded CSI, and computing and minimizing a loss function by comparing the CSI instance and the decoded CSI. The device may obtain one or more encoder weights and one or more decoder weights based at least in part on training the neural network model. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a method of wireless communication performed by a transmission/reception point (TRP) includes transmitting, at a first time and to a receiving entity, a first beam response report that describes, using a first level of granularity, beam responses of a set of positioning resources, each positioning resource to be transmitted by the TRP at different times using different beams; transmitting, at a second time and to the receiving entity, a second beam response report that describes, using a second level of granularity different from the first level of granularity, beam responses of at least a portion of the set of positioning resources; and transmitting the set of positioning resources using the different beams. The TRP may receive positioning information from the receiving entity, the positioning information comprising measurements of at least some of the positioning resources, a positioning estimate, or combinations thereof.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a receiving entity (RE), e.g., a user equipment or base station, receives a positioning resource beam configuration that defines a set of positioning resources, each positioning resource being transmitted by a transmission/reception point (TRP) at different times using different beams, each of the different beams having a set of beam characteristics that differs from the set of beam characteristics of another of the different beams in at least one beam characteristic. The RE performs positioning measurements on the different beams at the different times, at least based on the sets of beam characteristics, and sends positioning information to the TRP, the positioning information comprising at least some of the positioning measurements, a positioning estimate, or combinations thereof.

In an aspect, a receiving entity receives information that characterizes a set of positioning signals to be transmitted by a transmission/reception point (TRP) using a set of transmission beams, the information comprising at least one antenna element radiation pattern, at least one antenna element array configuration, and, for each beam in the set of transmission beams, information identifying at least one precoding matrix. The receiving entity performs measurements of the positioning signals transmitted by the TRP, and calculates at least one positioning measurement estimate based on at least some of the at least one antenna element radiation pattern, the at least one antenna element array configuration, the information identifying at least one precoding matrix, and the positioning measurements. The receiving entity sends positioning information to the TRP. The positioning information may include the at least one positioning measurement estimate.

Abstract: Techniques are described for wireless communication. An orthogonal frequency-division multiple access (OFDMA) configuration of an uplink channel is identified for communications in an unlicensed radio frequency spectrum band. An OFDMA waveform is generated based on the identified OFDMA configuration. The OFDMA waveform is communicated in a signal in the unlicensed radio frequency spectrum band. A virtual cell identifier of a first base station may be associated with transmissions between the first base station and a first user equipment (UE). A set of common resource blocks may be identified for transmission of a demodulation reference signal (DM-RS) between the first base station and the first UE. A configuration of an uplink channel may be dynamically selected for uplink communications in an unlicensed radio frequency spectrum band. A waveform may be generated based on the selected configuration. The waveform may be communicated in a signal in the unlicensed radio frequency spectrum band.
