Abstract: Certain aspects of the present disclosure provide techniques for measurements on a first frequency band applicable to procedures on a second frequency band. A technique that may be performed by a user equipment (UE) may include sending a base station (BS) an indication of the first frequency band, which may be a preferred measurement frequency band. The UE may then measure one or more reference signals (RSs) on the preferred measurement frequency band. The UE may then apply the measurements of the one or more RSs on the preferred measurement frequency band for one or more procedures on the second frequency band.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a data packet to a user equipment (UE). The data packet may have an associated packet delay budget to maintain a quality of experience for a user of the UE. The UE may determine a packet delivery time associated with the packet based on a communications latency and a signal processing latency. The UE may assess the packet delay budget and determine a remaining delay budget based on the packet delivery time. The UE may report the remaining delay budget to the base station in a feedback message. Based on the feedback message, the base station may determine to adjust a transmission time for subsequent data packet transmissions to improve data packet transmission and processing reliability.

Abstract: A scheduled entity receives a communication from a scheduling entity that facilitates a configuration on how to connect with a plurality of candidate cells. The scheduled entity then exchanges information about the plurality of candidate cells with the scheduling entity via Layer 1 (L1)/Layer 2 (L2) signaling, and connects with at least one of the plurality of candidate cells based on the L1/L2 signaling and the configuration. In another example, a scheduling entity transmits a communication to a scheduled entity to pre-configure the scheduled entity on how to connect with a plurality of candidate cells. The scheduling entity then receives information about the plurality of candidate cells from the scheduled entity via L1/L2 signaling, and dynamically selects via the L1/L2 signaling at least one of the plurality of candidate cells to serve the scheduled entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, via a sensor included within the UE, information associated with a base station. For instance, the UE may receive, via a camera included within the UE, an image of the base station. In some cases, the information associated with the base station may also include environment information identifying an antenna of the base station. The UE may then perform, based on the received information, a beam management procedure to track a UE beam corresponding to a base station beam, and communicate with the base station based on the beam management procedure.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for detecting when a control link between a user equipment (UE) and a base station is lost and recovering the control link. In one example, a UE may detect that a control link with a base station is lost based on a timer or counter expiring or based on failing to receive signaling from the base station. In another example, a UE may be configured to transmit uplink transmissions to a base station to maintain a control link with the base station, and the base station may detect that a control link with the UE is lost if the base station fails to receive one or more uplink transmissions from the UE. If the control link is lost, the base station and the UE may communicate to re-establish the control link.
