METHOD AND DEVICE FOR THE SEGMENTATION OF THE RADIO CONTROL CHANNEL IN RADIO COMMUNICATIONS SYSTEMS WITH VARIABLE BANDWIDTHS

摘要

The invention relates to a method and device for the temporal and frequency-related segmentation of the radio control channel in radio communications systems with variable bandwidths. The aim of the invention is to suitably code the radio control channel BCH in a 3G mobile radio communications system so that an efficient and rapid access is guaranteed for both terminals of lower power classes with a lower broadband capacity as well as terminals of the upper power classes with a higher broadband capacity. In the inventive method, information blocks are transmitted from the base station to the terminals on a radio control channel. The information blocks are transmitted on a subcarrier comprised of at least one individual carrier, whereby the transmission is temporally segmented according to the total bandwidth of the radio communications system and according to the minimum supported bandwidth of a terminal and is carried out in a segmented manner in frequency hops.
