    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: Approaches are described for receiving downlink signals simultaneously where analog beamforming is being used to increase the link budget between the base station and user equipment (UE). Alternatives within these approaches include the UE determining the synchronization signal block (SSB) to receive when there are multiple SSBs from different cells in a slot, and determining whether there are other signals in the same symbols with the selected SSB based on the type of signal and the SSB's functionality. In the case where there are another downlink signals channel state information-reference signal (CSI-RS) or physical downlink shared channel (PDSCH) from another cell, the UE selects the corresponding quasi co-location (QCL) assumption to receive the signals. Optionally, the UE can report whether it can support one or two QCL-TypeD at a time and whether it supports SSBs in different cells multiplexed in overlapped symbols.

    Abstract: A user equipment (UE) is configured to simultaneously connect to a primary cell (PCell) serving a primary component carrier (PCC), a primary secondary cell (PSCell) serving a primary secondary component carrier (PSCC) and at least one secondary cell (SCell) serving a secondary component carrier (SCC), wherein the PSCell is in a deactivated state. The UE receives a radio resource management (RRM) measurement configuration comprising a PCC measurement object (MO) configuration, a PSCC MO configuration, and an SCC MO configuration, determines a PCC MO carrier specific scaling factor (CSSF), a PSCC MO CSSF, and an SCC MO CSSF and applies each respective CSSF to a measurement period corresponding to each of the PCC MO, the PSCC MO, and the SCC MO.

    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) having dual connectivity. The UE can communicate with a first primary base station in a first primary cell (PCell) and a second primary base station in a second PCell. The UE has dual connectivity in the second PCell using a first wireless carrier to communicate with the second primary base station and a second wireless carrier to communicate with a secondary base station in a primary secondary cell (PSCell). The UE receives a message from the first primary base station to perform a handover procedure. The UE performs the handover procedure according to the received message, and further perform an addition procedure for the secondary base station in parallel with the handover procedure. A start time of the addition procedure can be before an end time of the handover procedure.

    Abstract: Some aspects include an apparatus, method, and computer program product for beamforming to perform received signal strength indicator (RSSI) measurements in a 5G wireless communications system. This beamforming may apply to RSSI measurements in an unlicensed spectrum. In some aspects, user equipment (UE) may use beam sweeping to analyze multiple received beams and to determine an RSSI measurement. When using beam sweeping, network nodes may use scheduling and/or measurement restrictions to avoid data collisions. These restrictions may apply to multiple active serving cells. In some aspects, a UE may use beam selection to determine an RSSI measurement. For example, the UE may select one or more beams from a serving component carrier (CC). In some aspects, a network node may indicate to the UE which beams to use for the RSSI measurement. In some aspects, the UE may use a frequency domain resource to perform the RSSI measurement.
