    Abstract: The present disclosure is directed to systems and methods for determining a starting point of a measurement gap. For example, the present disclosure is directed to a user equipment (UE) that includes a memory and processor circuitry coupled to the memory. The processor circuitry may be configured to receive an indication of a measurement gap timing advance. The processor circuitry may be further configured to, based on the indication of the measurement gap timing advance, determine a starting point of a measurement gap in a dual connectivity mode that provides dual connectivity with a new radio (NR) and an evolved universal mobile telecommunications system terrestrial radio access (EUTRA). The NR may serve as a master Radio Access Network (RAN) and the EUTRA may serve as a secondary RAN. The processor circuitry may also be configured to perform a signal quality measurement during the measurement gap, wherein the signal quality measurement is performed on a target cell of the NR or EUTRA.

    Abstract: A user equipment (UE) is configured to simultaneously connect to a primary cell (PCell) and a primary secondary cell (PSCell) of a wireless network, wherein a primary component carrier (PCC) of the PCell and a primary secondary component carrier (PSCC) of the PSCell are both in frequency range 1 (FR1). The UE receives a PCC measurement object (MO) configuration, a PSCC MO configuration, and an inter-frequency MO with no measurement gap configuration, determines a PCC MO carrier specific scaling factor (CSSF), a PSCC MO CSSF, and an inter-frequency MO with no measurement gap CSSF and applies each respective CSSF to a measurement period corresponding to each of the PCC MO, the PSCC MO, and the inter-frequency MO with no measurement gap to determine a scaled measurement period corresponding to each of the PCC MO, the PSCC MO, and the inter-frequency MO with no measurement gap.

    Abstract: A user equipment (UE) may support concurrent synchronization signal block (SSB) inter-frequency measurement without a measurement gap (MG). The UE may also, or alternatively, support concurrent SSB inter-frequency measurement in intra-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band) and/or inter-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band). The UE may report concurrent SSB based inter-frequency measurement as a NEEDFORGAP information element (IE), which may include one or more of a variety of parameters regarding UE measurement capabilities. Scheduling restrictions (e.g., restrictions to downlink and uplink communications) are also enabled based on UE measurement capabilities, including scheduling restriction for frequency range 1 (FR1), frequency range 2 (FR2), and cross frequency range scenarios.

    Abstract: Apparatuses, systems, and methods for performing dual active protocol stack handovers in a frequency range above 24 GHz. A UE may transmit an indication to a base station indicating a dual active protocol stack (DAPS) handover capability of the UE corresponding to a frequency range (FR) above 24 GHz. The UE may receive, from a target cell of the one or more cells, a command to perform a DAPS handover from a source cell to the target cell. While performing the DAPS handover and maintaining a data connection with the source cell, the UE may perform measurements on the target cell followed by a physical random access channel (PRACH) procedure. The UE may then receive a source cell release command from the target cell and release the data connection with the source cell.
