    Abstract: Methods, systems, and devices for wireless communications are described in which a network entity may use a lower power sleep procedure to reduce power consumption, and monitor for a wake-up signal (WUS) from at least one user equipment (UE) during configured WUS occasions. The WUS from one or more UEs may provide information of one or more attributes of data traffic that is present at a transmit buffer of the one or more UEs. A WUS configuration may be provided from a network entity that allows the selection of a particular WUS to indicate one or more attributes of the data traffic at the UE. The WUS may convey information such as buffer status, power headroom, a priority of traffic, latency targets of the traffic, or any combinations thereof. The WUS may also give an indication of a requested duration of an active mode at the network entity.

    Abstract: Methods, systems, and devices for wireless communication are described. A first wireless communications device may receive, from a second wireless communications device, a signal that is indicative of a phase-change pattern applied to communications between the first wireless communications device and the second wireless communication device by a reconfigurable intelligent surface reflecting the communications. The first device may determine the phase-change pattern from the signal. The first device may transmit a message to the second wireless communications device, wherein at least one of a content or a transmission property of the message is based at least in part on the phase-change pattern.

    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, control signaling identifying a configuration of a set of time intervals for communication with the base station, the set of time intervals including a subset of the time intervals for which the UE is to perform a physical layer security procedure. In some cases, the UE may activate a timer associated with performing the physical layer security procedure in response to a trigger. The UE and the base station may communicate one or more messages using the physical layer security procedure, for example, in the subset of the time intervals identified by the control signaling, while the timer is active, or both. The physical layer security procedure may involve the UE performing physical layer security encoding, signal jamming, or both.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus for wireless communication at a wireless node comprises one or more memories, and one or more processors, coupled to the memory. The one or more processors can be configured to transmit or receive tri-state feedback indicating a result of decoding one or more communications. The tri-state feedback can be associated with three potential states. The three potential states can indicate whether (i) decoding of a control channel was unsuccessful, (ii) decoding of the control channel was successful and decoding of a data channel was unsuccessful, or (iii) decoding of the control channel and the data channel was successful.

    Abstract: A UE includes: a transceiver; a memory; and a processor configured to: receive first and second discontinuous reception configurations for first and second discontinuous reception groups; receive first and second positioning signal configurations for first and second positioning signals associated with the first and second discontinuous reception groups, respectively; measure the first positioning signal during a first active time of the first discontinuous reception group; and measure the second positioning signal during a fixed second active time or during a variable third active time, the fixed second active time having a fixed duration of the second discontinuous reception group and the variable third active time having a variable duration of the second discontinuous reception group.
