Device and cell setting method

Abstract

A device is disclosed that is used as a first device in a radio communication system including the first device, a second device communicating with the first device, and a user equipment communicating with the first device. The device includes a processor being configured to acquire from the second device, a plurality of parameters used for an initial cell setting, the plurality of parameters including at least one of: information indicating a center frequency, a bandwidth and a duplex mode of a cell, a physical cell ID, information related to a master information block (MIB) for the initial cell setting, information related to a system information block (SIB) for the initial cell setting, and maximum transmission power. Additionally, the first device is a remote radio unit and the second device is a central unit. Further, the first device performs a predetermined layer function. In another aspect, a method is disclosed.
