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.

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: This disclosure provides techniques for activation of a secondary cell by a user equipment (UE) operating in a wireless network. For example, a UE receives a command to activate a secondary cell of the wireless network for wireless communication, and determines whether timing information is known by the UE for the secondary cell. Based on the determination, the UE performs a first secondary cell activation within first time period based on the timing information being known, or performs a second secondary cell activation within a second time period based on the timing information being unknown. After which, the UE wirelessly communicate data over the wireless network using the secondary cell, based on the secondary cell being activated.
