Abstract: A user equipment (UE) may receive, from a base station (BS) configured to support activation of a secondary cell (SCell), a request to provide a measurement report. In response to the request, the UE may perform one or more measurements on the SCell using one or more reference signals (RSs). Additionally or alternatively, the UE may generate the measurement report based on the one or more measurements and further transmit the measurement report to the BS. In some embodiments, the UE may further determine a pathloss estimation based on the one or more measurements.

Abstract: A network may transmit either beam deployment information or beam number information to a user equipment (UE) carried on a train and configured for operation in the millimeter wave band. The deployment information may include deployment related distance parameters or azimuth angle spread parameters. The beam number information may indicate a number of network beams associated with a current cell. The UE may determine a number of UE receive beams based on deployment information or the network-indicated number of network beams. The UE may transmit feedback to the network, indicating the number of UE receive beams. Alternatively, the network may send a configuration message indicating a first number of UE receive beams to the UE, which the UE may treat as an upper bound or lower bound in its determination of a desired number of UE receive beams. The UE may transmit the desired number to the network.

Abstract: The present disclosure relates to devices, apparatuses, and methods for enhanced PHR reporting in support of UE antenna scaling. A wireless device, which comprises at least one antenna array each comprising a plurality of antenna elements may perform antenna scaling by activating or deactivating at least one of the plurality of antenna elements (with corresponding RF chains) of one or more antenna arrays. The wireless device may generate a power headroom (PHR) report based at least on a difference between beamforming gains obtained after the antenna scaling and before the antenna scaling. The wireless device may then send the PHR report to a base station in communication with the wireless device.

Abstract: A user equipment (UE) is configured to establish a connection to a base station, wherein the base station configures the UE with a first beam corresponding to a first transmission reception point (TRP) and a second beam corresponding to a second TRP, wherein the first and second beam are in frequency range 2 (FR2) and wherein the UE does not support simultaneous reception of multiple beams in FR2, detect a beam failure during a beam failure detection (BFD) evaluation period, identify one or more candidate beams during a candidate beam detection (CBD) evaluation period and transmit a beam failure recovery (BFR) request to the base station.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform measurements on reference signals or synchronization signal. In an example, timing requirements for performing such measurements can be dynamically changed depending on, at least, a measurement on one of the reference signal or the synchronization signal.

Abstract: The present application relates to an improved method of operating a user equipment (UE), comprising: receiving, at the UE, a configuration of at least a first Channel Measurement Resource (CMR) set and a second CMR set for group-based beam reporting (GBBR) and performing, at the UE with at least a first antenna panel (and possibly multiple antenna panels), a first plurality of intracell, multiple TRP, Layer 1 Reference Signal Received Power (L1-RSRP) measurements. The first CMR set and second CMR set each comprises a plurality of resources (e.g., Synchronization Signal Block (SSB) resources and/or Channel State Information Reference Signal (CSI-RS) resources), and performing the first plurality of L1-RSRP measurements comprises performing a measurement using a number of fine beams (formed by one or more antenna panels) for one or more of the plurality of resources (up to and including each of the resources) in the first and second CMR sets.

Abstract: Embodiments of the present disclosure enable a user equipment (UE) to performing inter-Radio Access Technology (RAT) measurements. The UE determines whether one or more inter-RAT measurement object (MO) is configured with or without a measurement gap (MG). When the one or more inter-RAT MO is on an NR serving component carrier (CC) with the MG, the UE performs an inter-RAT measurement on the NR serving CC based on whether the MG is fully overlapped or partially overlapped with synchronization signal blocks (SSBs) of a target MO of the one or more inter-RAT MO. When the one or more inter-RAT MO is on the NR serving CC without the MG, the UE performs the inter-RAT measurement on the NR serving CC based on whether a target SSB of the target MO is within or outside an active bandwidth part (BWP) of the NR serving CC.
