    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: The present application relates to devices and components including apparatus, systems, and methods to perform cell reselection. In an example, timing requirements for synchronization signal processing are defined based on a beam sweeping capability of the device. Synchronization signals are received and processed according to the timing requirements to complete a cell reselection procedure. In another example, location data of the device is used to look up a database of cell identifiers. A cell identifier is determined based on the look-up and a cell reselection procedure is performed using the cell identifier.

    Abstract: Systems and methods for performing timing advance (TA) validation at a user equipment (UE) for a TA to be used when transmitting a configured grant small data transmission (CG-SDT). Mechanisms for bounding one or more measurement windows during which one or more synchronization signal blocks are measured during a reference signal received power (RSRP) measurement method of the TA validation are discussed, and may be set using information corresponding to timing drift due to relativistic effects, clock differences between a UE and a base station, and/or information about a UE discontinuous reception (DRX) cycle. Further, time interval limitations between various events attendant to such an RSRP measurement method are discussed as being determined using information corresponding to timing drift due to relativistic effects, clock differences between a UE and a base station, information about a DRX cycle used at the UE, and/or a maximum TA timer duration.

    Abstract: Techniques for changing a Transmission Configuration Indication (TCI) state by a user equipment (UE) operating in a wireless communications system are provided. The UE receives a first message including a TCI state change command from a network and determines, based on the first message, whether a time offset/frequency offset (TO/FO) and a reception (Rx) beam for a new TCI state are known by the UE. Based on the determination, the UE calculates a time delay of the UE to be prepared to receive a reference signal with the new TCI state, generates a second message indicating the time delay of the UE for the new TCI state, and transmits the second message to the network.
