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: Some aspects relate to apparatuses and methods for implementing mechanisms for performing handover, radio link monitoring (RLM), beam failure detection (BFD), and candidate beam detection (CBD) within the unlicensed spectrum when a listen-before-talk (LBT) failure occurs and/or when a user equipment (UE) performs receiving (RX) beam sweeping. For example, a UE is configured to receive a handover command to connect to a target cell. The UE is further configured to determine a search time and an interruption time uncertainty during a handover procedure initiated by the handover command and in response to a LBT failure or the UE performing a beam sweeping operation. The UE can further determine a handover delay based on the search time and the interruption time uncertainty. In response to a time period for performing the handover procedure exceeding the handover delay, the UE can cease the handover procedure.

Abstract: A user equipment (UE) is configured to establish a network connection including a new radio (NR)-NR dual connectivity band combination wherein a primary cell (PCell) of a primary cell group (PCG) and a primary secondary cell (PSCell) of a secondary cell group (SCG) both operate on frequency range 1 (FR1) and wherein at least one cell of either the PCG or the SCG operates on frequency range 2 (FR2). The UE receives a measurement gap timing advance parameter, selects one subframe from multiple serving cell subframes and determines a starting point for a configured per-frequency range (FR) measurement gap based on the measurement gap timing advance parameter and the selected subframe.
