摘要： Methods, systems, and devices provide improved proximity services. In one aspect, a base station includes an information generating module and an information transmission module. The information generating module generates control information for causing a mobile device to initiate a discovery signal transmission procedure. The discovery signal transmission procedure allows the mobile device to be discovered. The information transmission module transmits the control information to the mobile device. In another aspect, a mobile device includes an information receiving module, a control module, and a signal transmission module. The information receiving module receives control information. The control module initiates a discovery signal transmission procedure for proximity services responsive to the information receiving module receiving the control information. The discovery signal transmission procedure includes generating a discovery signal allowing the mobile device to be discovered. The signal transmission module broadcasts the discovery signal.

摘要： 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.
