초록 ▼

The present invention relates to a base station (1, 10, 20) and a mobile terminal (40, 50, 60) as well as a communication method for communicating in a wireless radio communication system. Thereby, the information is transmitted and received in medium access control frames of the communication syste

The present invention relates to a base station (1, 10, 20) and a mobile terminal (40, 50, 60) as well as a communication method for communicating in a wireless radio communication system. Thereby, the information is transmitted and received in medium access control frames of the communication system, whereby the transmission power of at least a broadcast control channel and a frame control channel in a respective medium access control frame transmitted by a base station is increased after certain time intervals to an increased transmission power level as compared to the transmission power level of other medium access control frames transmitted during said time intervals. The transmission of at least a broadcast control channel and a frame control channel with significantly increased power levels from time to time allows new mobile terminals trying to gain access to a base station to connect with this base station even if the effectively used transmission power is reduced on the basis of the transmission conditions of already connected mobile terminals.
