    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), that is configured for demodulation reference signal (DMRS) bundling, may receive a control message that schedules first and second sets of repetitions of an uplink transmission. The UE may determine a phase coherency configuration to be applied for DMRS transmissions corresponding to each set of repetitions. The phase coherency configuration may be determined based on a phase coherency capability of the UE, and the phase coherency configuration may specify that phase coherency is to be maintained for one or more of the first set of repetitions separate from one or more of the second set of repetitions. The UE may transmit the first set of repetitions with a first set of demodulation reference signals and the second set of repetitions with a second set of demodulation reference signals in accordance with the phase coherency configuration.

    Abstract: Aspects are provided which allow a base station to provide RACH configuration(s) indicating RACH occasions which correspond to wake up occasions of a base station according to a power savings mode of the base station. The base station sends one or more RACH configurations indicating ROs to a UE, and then monitors the ROs associated with the power savings mode. The UE determines the ROs associated with the power savings mode, and sends a wake up signal to the base station in at least one of the determined ROs. The base station obtains the wake up signal from the UE in at least one of the monitored ROs. Here, the wake up signal comprises a RACH message. As a result, network power consumption may be optimized through designed configurations which allow a UE to wake up a sleeping base station via a RACH message.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, based at least in part on a key derivation function and a set of physical layer parameters, a secret key for encrypting a unicast physical channel at a physical layer, wherein the secret key is a UE-specific secret key. The UE may transmit, to a base station, an encrypted transmission over the unicast physical channel based at least in part on the secret key. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive first signaling, and may transmit a first wake-up signal (WUS) based on information associated with a channel, where the information may be determined based on receiving the first signaling. The UE may monitor one or more channels, during a duration, for one or more signals based on transmitting the first WUS. If the UE fails to receive the one or more signals via the one or more channels during the duration, the UE may transmit a second WUS after the duration. The UE may communicate second signaling with a network entity based on transmitting the first WUS based on the information and successfully receiving the one or more signals, or based on transmitting the second WUS after the duration and successfully receiving one or more additional signals.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform an operation to obtain one or more channel state information (CSI) resources (e.g., new resources) from a set of resources indicated by a CSI report configuration. For example, the UE may aggregate or separate respective resources of the set of resources to obtain one or more CSI resources. The operation may be performed based on a first number of antenna ports associated with each resource of the set of resources and a second number of antenna ports associated with a codebook configuration. Thus, performing the operation may result in the UE forming one or more CSI resources for measuring CSI on the one or more CSI resources. The UE may transmit a CSI report based on measuring the CSI for a set of reference signals received on the one or more CSI resources.
