The present invention discloses a method and a base station for allocating the dedicated random access resource. In the method, first, the base station allocates the dedicated random access preamble to the user equipment (UE), and allocates the predetermined physical random access channel (PRACH) to which the dedicated random access preamble corresponds in the allocated radio frame; then, the base station transmits the signaling to the UE, wherein, the signaling includes the time domain information and the frequency domain information of the predetermined PRACH. The technical solution provided by the present invention can allocate the same dedicated random access preamble for different PRACH channels to different UEs, and can improve the utilization efficiency of the dedicated random access preamble.

L'invention concerne un procédé et une station de base d'allocation de ressources utilisant un accès aléatoire. Selon ledit procédé, un préambule utilisant un accès aléatoire est alloué à un terminal par la station de base; un canal d'accès aléatoire physique (PRACH) prédéterminé dudit préambule utilisant un accès aléatoire dans une trame sans-fil est alloué (S401); un signal, portant une information relative au domaine temporel et une information relative au domaine fréquentiel dudit PRACH prédéterminé, est envoyé au terminal par la station de base (S403). L'invention permet d'allouer le même préambule utilisant un accès aléatoire à différents terminaux dans différents canaux PRACH et d'accroître l'efficacité d'un préambule utilisant un accès aléatoire.
