Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform both a channel estimation and a non-linearity estimation (e.g., a power amplifier (PA) model estimation) on a demodulation reference signal (DMRS) transmitted by a base station. For example, the DMRS may include two portions that correspond to two peak-to-average power ratio (PAPR) values. Low PAPR values may enable the UE to perform the channel estimation, and high PAPR values may enable the UE to perform the PA non-linearity estimation. Accordingly, a first portion of the DMRS may correspond to a lower PAPR value, and the second portion of the DMRS may correspond to a higher PAPR value. In some examples, the base station may signal different parameters for each portion of the DMRS to the UE, or the UE may use fixed values to receive each portion of the DMRS.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a first user equipment (UE) may receive a message from a second UE via a set of one or more antennas, where a first symbol period and a second symbol period of the message include a duplicated signal, and the first symbol period is immediately prior to the second symbol period in a time domain. The first UE may calculate a correlation between first data included in the first symbol period and second data included in the second symbol period of the message for each antenna of the set of one or more antennas. In some cases, the first UE may power down at least one radio frequency chain based on the result of the calculated correlation satisfying a threshold value.

Abstract: A transmitting device maps complex valued symbols in sequence to physical resource blocks for a sidelink transmission. The transmitting device reserves a first symbol of a subframe, where resource elements in the first symbol of the subframe are not considered in mapping the complex valued symbols to the physical resource blocks for the sidelink transmission. The transmitting device transmits the sidelink transmission after mapping the complex valued symbols to the physical resource blocks. A receiving device receives the sidelink transmission and decodes the sidelink transmission to determine complex valued symbols that are mapped in sequence to physical resource blocks of the sidelink transmission, where the complex valued symbols are not mapped to resource elements in a first symbol of a subframe.

Abstract: IQ impairments compensation in sub-terahertz (sub-THz) communication is disclosed. According to some aspects, a user equipment (UE) determines an estimated in-phase (I) and quadrature phase (Q) impairment of the UE, the IQ impairment of the UE comprising a mismatch of phase and/or amplitude, between an I path and a Q path within an analog receiver circuitry of the UE, and reports the estimated IQ impairment of the UE to a base station (BS). The BS determines a pre-compensation to compensate for the estimated IQ impairment of the UE and uses the determined pre-compensation when transmitting to the UE.

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: Example aspects include a method, apparatus, and computer-readable medium for wireless communication at a base station of a wireless communication network, comprising obtaining a downlink channel response of a downlink channel. The aspects further include determining to perform tone reservation with separated tone reservation null indications on a downlink transmission from the base station to a user equipment (UE). Additionally, the aspects include selecting a plurality of channel nulls of the downlink transmission. Additionally, the aspects include assigning a tone reservation quantity to each channel null of the plurality of channel nulls resulting in a plurality of tone reservation quantities. Additionally, the aspects include sending, to the UE via the downlink channel, a tone reservation report. Additionally, the aspects include sending, to the UE via the downlink channel, the downlink transmission according to the plurality of channel nulls and the plurality of tone reservation quantities.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless networks may maintain up-to-date location information for the UE by periodically determining the location the UE using a low power transponding mechanism while the UE is in an inactive state. The UE may monitor a first beam to receive one or more transponder search signals during one or more transponder occasions, and between paging attempts from one or more of the base stations of the network. The UE may receive the one or more transponder search signals, and may transmit a transponder response message to a base station including a UE identifier associated with the inactive state. The base station may receive the transponder response message, and may conduct various location measurements for the UE using the transponder response.

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.
