Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of connected discontinuous reception (C-DRX) configurations. The set of C-DRX configurations may include a first C-DRX configuration and a second C-DRX configuration, where at least one C-DRX configuration in the set of C-DRX configurations is a UE-group common C-DRX configuration. The set of C-DRX configurations may correspond to a discontinuous transmission (DTX) cycle of the base station. The UE may select a C-DRX configuration from the set of C-DRX configurations based on receiving the control signaling from the base station. Accordingly, the UE may use the selected C-DRX configuration to communicate with the base station. The selected C-DRX configuration may enable the base station to operate with reduced power consumption and higher DTX efficiency, among other benefits.

Abstract: Apparatus, methods, and computer program products for SSB adaptive power transmission are provided. An example method includes performing a measurement of a medium for transmission of an SSB. The example method further includes transmitting, based on the measurement, the SSB at an SSB candidate position from a set of SSB candidate positions, wherein transmitting the SSB comprises transmitting using a first transmission power level if the measurement is within a first range and transmitting using a second transmission power level if the measurement is within a second range, the second transmission power level being lower than the first transmission power level.

Abstract: Aspects relate to providing a status bit to a base station, where the status bit indicates whether all of multiple downlink transmissions have been successfully decoded. In an aspect, a user equipment (UE) receives a plurality of downlink transmissions from a base station, and generates a plurality of acknowledgement data respectively for the plurality of downlink transmissions, each of the plurality of acknowledgement data indicating whether a respective downlink transmission of the plurality of downlink transmissions has been successfully decoded. The UE further transmits, to the base station, at least one status bit based on the plurality of acknowledgement data, the at least one status bit indicating whether all of the plurality of downlink transmissions have been successfully decoded.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a downlink configuration including a set of resources for receiving downlink transmissions. The UE may determine a grant for performing uplink transmissions based on a radio resource control (RRC) message. The UE may determine, based on the downlink configuration, the grant, or both, an uplink configuration including a set of resources for transmitting the uplink transmissions at a set of uplink transmission occasions. In some aspects, the set of uplink transmission occasions may be arranged according to a non-uniform spacing pattern in a time domain. The UE may transmit, to a base station, one or more uplink transmissions based on the uplink configuration.

Abstract: Aspects of the disclosure relate to techniques for peak-to-average power ratio (PAPR) reduction based on a tone reservation (TR) algorithm. For a TR algorithm, a suitable subset of tones from among a full set of tones in a given resource allocation are reserved for use as peak reduction tones (PRT). An apparatus such as a transmission/reception point receives a set of one or more PRT sequences and stores them in memory. The transmission/reception point then determines a set of PRTs based on one or more later-received PRT sequence selection parameters. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive control signaling indicating a configuration for performing channel sensing. The configuration may include one or more parameters corresponding to a processing time associated with the channel sensing. The UE may adjust the processing time associated with the channel sensing based on the one or more parameters and a full duplex capability of the first UE. The UE may transmit, using a first set of resources, a sidelink message based on the adjusted processing time. In some examples, the UE may transmit a first data message associated with a first priority level and perform channel sensing for a second data message associated with a second priority level that is higher than the first priority level. The UE may drop the first data message, skip an interference cancellation, or a combination thereof.

Abstract: Aspects of the disclosure relate to power reduction measures that can be employed by wireless user equipment (UE) participating in an extended reality (XR) application. A wireless UE, while operating in a first power state, may receive, from an XR service provider, a plurality of packets corresponding to a video frame. The UE may reassemble and decode the received packets to reproduce the video frame. Once the UE determines it has received information sufficient to reproduce the video frame, the UE may enter a second power state, different from the first power state, for a predetermined amount of time. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a sub-band full-duplex (SBFD) configuration of a cell serving the UE. The SBFD configuration may indicate a first set of resources for downlink communications and a second set of resources for uplink communications. The first set of resources and the second set of resources may include non-overlapping frequency resources in a same time interval. The UE may receive a control message that indicates a pre-emption of the first set of resources or a cancellation of the second set of resources. Accordingly, the UE may determine that downlink transmissions in at least a portion of the first set of resources are pre-empted or that uplink transmissions in at least a portion of the second set of resources are cancelled based on the control message and the SBFD configuration of the cell.

Abstract: Systems, methods, and devices for wireless communication that support mechanisms signaling non-linearities to a victim user equipment (UE) for interference cancellation in a wireless communication system. A victim UE may experience interference from an uplink transmission by an aggressor UE to a base station. The victim UE may obtain a power amplifier model associated with the aggressor UE. The power amplifier may include a non-linearity model of a power amplifier of the aggressor UE causing the interference on the victim UE. The power amplifier model obtained by the victim UE may be dependent on various parameters, such as a transmit power used by the aggressor UE to transmit the uplink transmission causing the interference. Based on the aggressor UE transmit power, the victim UE may select parameters for power amplifier model and may estimate the interference caused by the uplink transmission for interference cancellation.
