Abstract: This disclosure describes methods, systems, and devices for measuring a reference signal received power (RSRP) in a user equipment (UE) that operates in machine type communication (MTC). In one example, a method involves receiving, from a radio access network (RAN) serving the UE, a resynchronization signal (RSS). The method also involves calculating a reference signal received power (RSRP) of the RSS.

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.

Abstract: Methods, systems, apparatus, and computer programs, for implementing dual-connectivity handover. In one aspect, a method includes determining, by user equipment (UE), whether the UE is capable of simultaneous communication with a source cell and a target cell, generating, by the UE, a handover indicator, the handover indicator having one or more fields structuring data that indicates that the UE is capable of simultaneous communication with the source cell and the target cell, transmitting, by the UE, the handover indicator to an access node, and receiving, by the UE and from the access node based on receipt by the access node of the handover indicator, a command to perform handover.

Abstract: Methods, apparatuses, and systems are disclosed for compensating for cell identification delays that are beyond the control of the UE, in connection with standards-specified cell identification timing limits. In frequency bands including both beam sweeping and listen-before-talk (LBT) requirements, a cell identification procedure may be significantly delayed due to LBT failure at the base station and/or beam misalignment between the base station and the UE. Therefore, UE cell identification timing constraints may be dynamically adjusted to compensate for such delays. For example, the time window allowed for cell identification of a neighbor cell may be dynamically increased in response to determining that one or more SSBs were not available at the UE during an SMTC occasion. In some scenarios, if the timing increase exceeds a predetermined threshold, the UE may restart the cell identification procedure, e.g., on the same frequency layer or on a different frequency layer.

Abstract: Techniques discussed herein may better ensure efficient fine time tracking during a second cell (SCell) activation procedure by using a tracking reference signal (TRS) that is User Equipment (UE) specific. A primary cell (PCell) may provide a UE with a TRS configuration that includes a UE-specific reference signal (RS) with periodicity or aperiodicity. In response to receiving a SCell activation command from the PCell, the UE may perform cell activation with fine time tracking in accordance with the UE-specific RS. As the delay time for the UE-specific RS may be less than the delay time for a system synchronization block (SSB) from the SCell, use of the UE-specific RS may expedite the cell activation procedure.

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 terminal may communicate through a first communication link with a first network. The terminal may include a transmitter that transmits, to a second network, a terminal capability indicating support for a measurement configuration. The terminal may include a receiver that receives, from the second network, network configuration information including a pattern for establishing a second communication link with the second network. The terminal may include a processor that, based on the pattern, establishes the second communication link with the second network while maintaining the first communication link with the first network. The network configuration information may be based on an independent frequency range (FR) measurement included in the terminal capability.
