METHOD FOR TRANSMITTING CONTROL INFORMATION FROM BASE STATION TO MOBILE STATION AND METHOD FOR RECEIVING CONTROL INFORMATION FROM BASE STATION AT MOBILE STATION

Japanese Patent JP3875422

B2

PROBLEM TO BE SOLVED: To transmit common control data which change in an amount at a cell by displaying the position of one piece of control information on a second channel on a first channel at a first point of time and transmitting one piece of control information through the second channel at a second point of time after the first point of time.
SOLUTION: A base station 301 enables the transmission of control information through a broadcasting control information channel 303 to a lot of mobile stations 302 and the designation of a point-to-multipoint(PTM) traffic channel 304 as well. The current network, location area and cell ID or the like in the fixed minimum quantity of certain control information to be transmitted through the channel 303 are transmitted by respective protocol data units(DU) 305. A remaining pointer DU 306 designates and transmits the real information to the channel 304 while containing only the display of contents and positions of cells in the channel constitution. Thus, even without securing relevant capacity in the beginning, because of common control structure, the capacity can be added.
