移動局装置、基地局装置、無線通信システムおよびランダムアクセス方法
Document Type and Number:
Japanese Patent JP5322832
Kind Code:
B2
Abstract:
A random access instructed by a base station apparatus and having a small delay is enabled in Advanced-EUTRA system. Upon detection of control data in any one of a plurality of component carriers, component carrier information, a preamble number, and random access channel information are extracted from the control data, and if the extracted information indicates dedicated preamble transmission, a random access channel position to be used is selected from information on random access of a component carrier specified in the component carrier information and the random access channel information, a random access preamble is generated from the information on random access and the dedicated preamble number, and the random access preamble is transmitted at the random access channel position.
