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: An inflatable tent includes an inflatable main body having a tent floor, an inner tent wall, an outer tent wall, and a tent roof, the inner and outer tent walls together defining an inflatable space therebetween and constituting a tent wall, and the tent floor, the inner tent wall, and the tent roof together enclosing a interior space. An inflation valve is provided on the outer tent wall, so that air is supplied into the inflatable space via the inflation valve. The inflatable tent also includes at least one entrance formed on the tent wall, a bathroom arranged in the interior space at a selected position, and a utility cabinet located outside the inflatable main body and including at least one water tank, which communicates with the bathroom via an inlet pipeline and a drain pipeline.
