Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node and via a first receiver component associated with the UE, a wakeup signal (WUS) or a reference signal indicating information including at least one of cell barring information, downlink buffer status report information, or an indication to monitor a synchronization signal. The UE may communicate, via a second receiver component associated with the UE, one or more signals based at least in part on the information included in the WUS or the reference signal. Numerous other aspects are provided.

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 base station, an indication that a plurality of physical downlink shared channel (PDSCH) communications are associated for purposes of demodulation reference signal bundling. The UE may determine whether a phase continuity is to be maintained for the plurality of PDSCH communications based at least in part on respective quasi-co-location assumptions for the plurality of PDSCH communications. The UE may process the plurality of PDSCH communications based at least in part on whether the phase continuity is to be maintained Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a transport block (TB). The UE may fail to successfully decode the TB. The UE may transmit a negative acknowledgement (NACK) message based at least in part on the failing to successfully decode the TB. The NACK message may indicate a quantity of repetitions for retransmitting the TB. 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 an indication of a configuration for a discontinuous reception (DRX) cycle periodicity, the indication including a selection of a non-integer number for the DRX cycle periodicity. The UE may receive one or more communications based at least in part on the configuration for the DRX cycle periodicity. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines a frequency hopping pattern for transmission of a physical random access channel (PRACH) preamble based on an associated PRACH coverage enhancement (CE) level, and transmits the PRACH preamble in accordance with the frequency hopping pattern and the associated PRACH CE level. A base station receives the PRACH preamble, and transmits a response (e.g., Msg2 or MsgA) to the PRACH preamble.

Abstract: Apparatus, methods, and computer-readable media for facilitating semi-static TCI configurations are disclosed herein. An example method for wireless communication at a UE includes receiving, from a base station, a first downlink message including a TCI state indicator. The example method also includes initiating a timer after receiving the first downlink message including the TCI state indicator. Additionally, the example method includes receiving, after the timer expires, subsequent downlink messages using the indicated TCI state until a second downlink message including a TCI state change indication is received. An example method for wireless communication at a base station includes transmitting, to a UE, a first downlink message including a TCI state indicator. The example method also includes initiating a timer after transmitting the first downlink message including the TCI state indicator. Additionally, the example method includes transmitting, after the timer expires, subsequent downlink messages based on the indicated TCI state.

Abstract: Certain aspects of the present disclosure provide techniques for using downlink control information (DCI) to trigger low power (LP) wake-up signal (WUS) monitoring. A method includes receiving, via a first receiver (e.g., a main receiver) of a user equipment (UE) while in an active mode, DCI that triggers monitoring for a WUS by a second receiver (e.g., a LP wake-up receiver (LP-WUR)) of the UE, wherein the WUS is associated with a first discontinuous reception (DRX) ON duration configured for the first receiver; in response to receiving the first DCI: transitioning, by the first receiver, from the active mode to an inactive mode; transitioning, by the second receiver, from the inactive mode to the active mode; and monitoring, by the second receiver while in the active mode, for the WUS during a WUS monitoring duration

Abstract: Disclosed are techniques for wireless communication. In an aspect, timing of a PRS instance is determined, and timing of a PO is determined based at least in part upon the timing of the PRS instance. UE transitions from DRX OFF state to DRX ON state and receives/measures the PO and PRS resource(s) of the PRS instance (e.g., without returning to DRX OFF state or sleep state until both the PO and PRS resource(s) are received/measured).
