Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adjust resources (e.g., time resources, frequency resources) used to transmit repetitions of uplink control information (UCI) over a physical uplink control channel (PUCCH). The UE may adjust two parameters corresponding to different scales (e.g., levels) of adjustment, where a first parameter corresponds to a number of repetitions of a PUCCH resource and a second parameter corresponds to a number of slots within each PUCCH repetition. The UE may adjust the resources based on the first parameter, the second parameter, a size of UCI, a maximum coding rate, or some combination thereof, such that the PUCCH resources carrying UCI satisfy the maximum code rate and UCI size.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a New Radio (NR) base station, an indication that includes a configuration for at least one reference signal. The UE may measure, while in an idle mode or inactive state, the at least one reference signal based at least in part on the indication of the configuration. In some aspects, the UE may further receive, from the NR base station, an activation associated with the at least one reference signal. The at least one reference signal may be measured based at least in part on the activation. 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 network entity, a channel state information (CSI) report configuration including multiple CSI reference signal (CSI-RS) transmit power configurations. The UE may transmit, to the network entity, the CSI report, wherein the CSI report is associated with at least one CSI processing parameter that is based at least in part on the multiple CSI-RS transmit power configurations. Numerous other aspects are described.

Abstract: Aspects are provided that allow a UE to perform DMRS bundling in PUSCH repetitions in response to a configuration from a base station indicating or enabling the UE to perform the DMRS bundling. The UE receives a configuration from a base station indicating to bundle DMRS in repetitions of an uplink data channel transmission for joint channel estimation. The UE determines a DMRS bundling window based on the configuration. The UE transmits the bundled DMRS in the DMRS bundling window. The base station performs the joint channel estimation based on the bundled DMRS. Improved link quality between the UE and base station and signal gains may accordingly result from applying DMRS bundling over multiple repetitions of PUSCH transmissions.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) determines a transmit power of at least one sensing reference signal (S-RS) transmitted by a network node, wherein the transmit power of the at least one S-RS is determined based on a transmit power offset relative to a transmit power of a reference channel or reference signal transmitted by the network node, and determines an enhanced channel estimate of the at least one S-RS based on the transmit power of the at least one S-RS.

Abstract: A signal processing method includes: receiving, at a UE, a PRS and a supplemental signal, the supplemental signal being a broadcast signal and spanning a first frequency range at least partially outside of a second frequency range spanned by the PRS; processing, at the UE, the PRS and the supplemental signal in combination, resulting in an effective signal bandwidth that is larger than the second frequency range, to determine position information; and at least one of: transmitting a capability message, from the UE to a network entity, indicating a processing capability of the UE to process, in combination, the PRS and the supplemental signal; or transmitting a signal-combination indication, from the UE to the network entity, indicating that the UE processed the PRS and the supplemental signal in combination to determine the position information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, first signaling identifying a configuration for a set of wake up occasions associated with an active state of the network entity. The UE may transmit, to the network entity, a wake up signal to transition the network entity from an inactive state to the active state based on the configuration for the set of wake up occasions. The UE may receive, from a network entity, second signaling identifying a cell active time during which the network entity remains in the active state. Numerous other aspects are described.
