Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station having one or more antenna ports, a communication that includes one or more data streams and a tone reservation signal, wherein a number of the one or more antenna ports is different than a number of the one or more data streams. The UE may perform channel estimation based at least in part on the communication. 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, from a base station, a phase tracking reference signal. The phase tracking reference signal is transmitted using a single carrier waveform and encoded within a time domain. Accordingly, the UE may decode, from the base station, a message, based at least in part on the phase tracking reference signal. Numerous other aspects are provided.

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: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for dedicated pilot signals associated with radio frequency impairment compensation. In some aspects, a user equipment (UE) and a network entity may support a signaling mechanism according to which the UE may measure and report, to the network entity, an imbalance between an in-phase (I) component and a quadrature (Q) component of a modulated signal. For example, the UE may request the network entity to transmit an out-of-band pilot signal to enable frequency domain residual side band (FDRSB) estimation at the UE and the UE may transmit measurement information associated with the IQ imbalance or the FDRSB estimation to the network entity. The network entity may receive the measurement information and compensate or correct signaling in accordance with the received measurement information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication to transmit tone reservation signaling, configured to reduce a peak-to-average-power-ratio for one or more of the UE or the base station, on one or more subcarriers outside of an allocated bandwidth that is allocated for an uplink communication scheduled for the UE. The UE may transmit, to the base station, signaling that includes the uplink communication within the allocated bandwidth and the tone reservation signaling on the one or more subcarriers. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may be configured to use intra-message antenna selection diversity (ASD). The UE may transmit a first portion of a scheduled message within a time interval using a first antenna element of the UE based on an intra-message antenna diversity configuration. The intra-message antenna diversity configuration may indicate a set of antennas available for transmission of the scheduled message. In some cases, the UE may transmit, within the same time interval, at least a portion of the scheduled message using at least a second antenna element of the UE that is different from the first antenna element. In some cases, a receiving UE may decode the first portion and the second portion of the scheduled message based on the intra-message antenna diversity configuration.

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 tone reservation on one or more subchannels allocated for phase tracking reference signals (PT-RSs); and transmit the uplink transmission or receiving the downlink transmission based at least in part on the request. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support short control messaging using index modulation on DMRS. In a first aspect, a method of wireless communication includes a base station determining a configuration action for a served user equipment (UE) in communication with the base station. The base station may then generate a short control message associated with the configuration action and map that short control message onto a set of inactive subcarrier resource elements (REs) of a demodulation reference signal (DMRS) sequence. The served UE may then receive the transmitted DMRS sequence and determine the short control message within the set of inactive subcarrier REs of the DMRS sequence. Other aspects and features are also claimed and described.

Abstract: A device generates an estimated size of encoded versions of one or more pictures of video data prior to generating the encoded versions of the one or more pictures. A physical layer of a radio system of the device is configured to send a message to a wireless base station. The message indicates a size value based on the estimated size of the encoded versions of the one or more pictures. The physical layer of the radio system receives an uplink grant notification in response to the message. Based on the uplink grant notification, the physical layer of the radio system sends packets to the wireless base station containing the encoded versions of the one or more pictures.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for lens design for full-duplex communication. In some aspects, a device may use a lens design that enables full-duplex operation through a lens by facilitating an avoidance or mitigation of self-interference during full-duplex operation. The lens may have a first, antenna-facing surface and a second, outward-facing surface and, to avoid or mitigate self-interference due to reflection off the lens, the first surface may have a first curvature associated with a relatively small radius. In such examples, the device may transmit wireless signaling from a transmitting element and a reflection off the lens may be dispersed or otherwise oriented away from a receiving element in accordance with a design of the first curvature. In some implementations, the lens may include an anti-reflective coating to further reduce reflection off the lens.
