Publication number: 20240107414Abstract: 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.Type: ApplicationFiled: September 23, 2022Publication date: March 28, 2024Inventors: Yu-Chieh HUANG, Kuhn-Chang LIN, Jen-Chun CHANG, Wen-Hsin HSIA, Chia-Jou LU, Sheng-Chih WANG, Chenghsin LIN, Yeong Leong CHOO, Chun-Hsiang CHIU, Chihhung HSIEH, Kai-Chun CHENG, Chung Wei LIN
