Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for switching a secondary cell to a primary cell. A user equipment (UE) monitors a first radio condition of the UE for beams of a primary cell and a second radio condition for beams of one or more secondary cells configured for the UE in carrier aggregation. The UE transmits a request to configure a candidate beam of at least one candidate secondary cell as a new primary cell in response to the first radio condition not satisfying a first threshold and the second radio condition for the at least one candidate secondary cell satisfying a second threshold. A base station determines to reconfigure at least one secondary cell as the new primary cell. The base station and the UE perform a handover of the UE to the new primary cell.

Abstract: In a docking station, a connecting port unit is mounted on a housing and is coupled to an external peripheral device. A connector is mounted on the housing and is coupled electrically to the connecting port unit. The connector is coupled electrically and directly with a portable electronic apparatus so as to provide a signal transmission path between the connecting port unit and the portable electronic apparatus when the portable electronic apparatus is mounted on the housing. The circuit unit is mounted in the housing, is coupled electrically to the connector, and receives and processes an external cable television signal so as to provide an output signal associated with the cable television signal to the portable electronic apparatus via the connector.
