Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor for two or more messages from a base station. The UE may transmit, to the base station, at least one bit (e.g., in first stage uplink control information (UCI)) that is based at least in part on combined acknowledgement feedback associated with the two or more messages and that indicates a subset of possible decoding events associated with the two or more messages. In some aspects, the UE may further transmit at least one additional bit (e.g., in second stage UCI) that is based at least in part on the combined acknowledgement feedback and that indicates a different subset of possible decoding events associated with the two or more messages. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support frequency hopping across subbands within a configured bandwidth part (BWP). A first network node may transmit a first control message to a second network node to indicate a set of one or more frequency hopping patterns for switching between two or more subbands within the BWP configured for the second network node. The first network node may, in some aspects, transmit a second control message that is indicative of a designated frequency hopping pattern from among the set of one or more frequency hopping patterns indicated via the first control message. The first and second network nodes may communication via a first subband and a second subband of the two or more subbands in accordance with the default or designated frequency hopping pattern.

Abstract: Methods, systems, and devices for wireless communication are described, including techniques for utilizing implicit or explicit signaling to indicate a cancellation of demodulation reference signal (DMRS) bundling. A first user equipment (UE) may perform DMRS bundling across physical sidelink channels transmitted to a second UE to enable the second UE to perform joint channel estimation. In some examples, based on a detected change, either at the first UE or the second UE, the first UE may signal to the second UE that the DMRS bundling is canceled. In some examples, the detected change may be a resource allocation change, a physical channel configuration change, a change in a quasi-colocation (QCL) relationship at the first UE, or a change in a transmission configuration indicator (TCI) state at the first UE. Additionally or alternatively, the first UE or the second UE may request the cancellation based on detected changes.

Abstract: Apparatus, methods, and computer-readable media for autonomous physical uplink shared channel repetition cancellation for energy-limited devices are disclosed herein. A user equipment (UE) may transmit, to a base station, a plurality of uplink channel repetitions. The UE may determine that a device power level associated with the UE does not exceed a predetermined threshold that corresponds to a power requirement to transmit a number of uplink channel repetition instances in the plurality of uplink channel repetitions. The UE may determine to not transmit the number of uplink channel repetition instances based on the device power level falling below the predetermined threshold. The UE may modify the device power level through an energy harvesting operation. Thus, the power efficiency and reliability of uplink channel repetitions can be increased.

Abstract: Methods, systems, and devices for wireless communications are described. Sidelink communications between user equipments (UE)s may include services that demand low latency and high reliability, such as extended reality (XR) and ultra-reliable low latency communications (URLLC). Given the latency demands for XR and URLLC, XR and URLLC may be higher priority than other communications types. A UE may determine that data for transmission over sidelink has a high priority level based on a remaining packet delay budget associated with the data. UEs may monitor for sidelink transmissions in accordance with network configured discontinuous reception (DRX) cycles. The DRX cycles configured by the network for sidelink communications, however, may not match with the periodicity of XR traffic. For XR communications, the transmitting UE may indicate an offset to apply to a DRX cycle such that the receiving UE may adjust the DRX cycle to match the periodicity of the XR communications.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be instructed to, or may autonomously determine to, extend a monitoring time period (e.g., by extending the on duration to cover more downlink transmissions, or by extending the on duration and continuing to monitor after on durations, or both). In some examples, a wakeup signal (WUS) or a downlink control information (DCI) message may explicitly indicate an amount of time to extend the on duration or inactivity timer (or to pause the inactivity timer). In some examples, the network may configure the UE with a power threshold (e.g., charging rate, discharging rate, energy harvesting rate, current power levels, or power headroom), or a traffic rate (e.g., number of transport blocks per time interval), and the UE may autonomously extend the on duration or timer if its energy levels or traffic rate exceeds the threshold.

Abstract: Methods, systems, and devices for wireless communications are described herein. A user equipment (UE) may generate a set of feedback bits corresponding to sidelink messages received via one or more sidelink channels. The UE may transmit a first sidelink message via a first feedback resource of a physical sidelink feedback channel occasion. The first sidelink message may include a first subset of the feedback bits. The UE may transmit at least two additional sidelink feedback messages via respective feedback resources. The first additional sidelink feedback message may include the first subset of feedback bits and a second subset of feedback bits encoded using an erasure coding function.

Abstract: Techniques for indicating system information block or paging waveforms for future communications may include a user equipment (UE) configured to identify a waveform configuration of a downlink (DL) signal including system information to be received from a base station during a random access channel (RACH) procedure in response to an indication of the waveform configuration of the DL signal. The UE may also be configured to receive, from the base station, the system information in response to the waveform configuration of the DL signal being identified.
