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: Some embodiments of the present disclosure relate to an integrated chip including an extended via that spans a combined height of a wire and a via and that has a smaller footprint than the wire. The extended via may replace a wire and an adjoining via at locations where the sizing and the spacing of the wire are reaching lower limits. Because the extended via has a smaller footprint than the wire, replacing the wire and the adjoining via with the extended via relaxes spacing and allows the size of the pixel to be further reduced. The extended via finds application for capacitor arrays used for pixel circuits.
