Abstract: PROBLEM TO BE SOLVED: To reduce or eliminate interference disturbances occurring between the multi-function control channels of a base station and its adjacent base station by encoding the data which are transmitted on a multi-function control channel via a single time slot and by means of a spread spectrum format. SOLUTION: One or 2 or more time slots 203 among those designated of a frame 201 which are designated in various ways carry data to be used for executing the channel access function for a user and are designated to be used as the multi-function control channels used at a remote terminal, when a modem function is executed. The multi-function control channel has the data which are encoded and transmitted by means of a spread spectrum format, by encoding the data which are carried on the multi-function control channel. Then all other remaining time slots 203 of the frame 201 are not spread.
