Abstract:
1. A signal transmission method over a forward traffic channel in cellular mobile communications that can simultaneously perform one or more high speed communications whose transmission rates are higher than or equal to a predetermined rate, and one or more low speed communications whose transmission rates are lower than the predetermined rate between a plurality of mobile stations and a base station, said signal transmission method comprising the steps of: checking, on a base station side, whether a communication request is made for a high speed communication; checking, if the communication request is made for a high speed communication, whether transmission power of all high speed communications performed simultaneously becomes greater than a predetermined first threshold value if the communication request as accepted; checking whether transmission power of all communications performed simultaneously becomes greater than a predetermined second threshold value if the communication request is accepted; and restricting acceptance of the communication request, if the transmission power of all high speed communications becomes greater than the first threshold value or the transmission power of all communications becomes greater than the second threshold value.
