Methods of transmitting and receiving data, and apparatus therefor

Data by the invention claims a wireless communication device (100): aAccording to launched data accessing signal, the signal and a second a random access transmission emission to the wireless signal station (200), derivation identifier according to the data, calling function identifier to is a using light identifier to the wireless communication device (100) is signal receiving then. The data (200) is received in wireless signal) by the following steps: The receiving random access signal, wherein the indication data received; the confirm a random access signal indication's data, derivation identifier according to the data by, a identifier comprise a proceeding from the wireless signal station (200) and then, transmitting and receiving end of the identifier then transmission scheme output end.
