METHOD FOR CONTROL CHANNEL RANGE EXTENSION IN A CELLULAR RADIO SYSTEM, AND A CELLULAR RADIO SYSTEM

摘要

The invention relates to a method for control channel range extension and a cellular radio system. In the cellular radio system, each cell has at least one base station (BS) which is in contact with mobile stations (MS) within its area. In a method of the invention, in at least one time slot comprising control channels is used a stronger channel coding than in the time slots of traffic channels. A method and a cellular radio system of the invention enable a range of a base station applying an SDMA technique to be extended to correspond to a range of the traffic channels of the base station in question.
