Abstract

A user apparatus and a control information detection method executed by a user apparatus are disclosed. The user apparatus includes a memory that stores a preamble and identification information of the user apparatus; a processor that detects control information, addressed to the user apparatus, by monitoring a candidate area of a common candidate area where a plurality of user apparatuses commonly perform monitoring and an individual candidate area for the user apparatus; and a transmitter that transmits the preamble to a base station. The processor monitors, during a period when the user apparatus monitors a random access response, the individual candidate area using the identification information of the user apparatus to detect control information that is scrambled by the base station using the identification information of the user apparatus.
