Tdma radio communication system achieving simultaneous assignment of channels to multiple terminal stations

Abstract

A TDMA radio communication method including the steps of: providing a latter part of each of super frames with an assignment information notification period which is preceded by an assignment processing period, and providing a remaining part of the each of the super frame with an assignment request collecting period; transmitting, from a terminal station to a base station, assignment request information using a plurality of frames included in the assignment request collecting period; transmitting, from the base station to the terminal station, frame structure information and assignment information over a plurality of frames included in the assignment information notification period; and carrying out, in the base station, channel assignment of a radio channel, changes of the frame structure and of the channel assignment in response to timings of the super frames. This makes it possible to solve a problem involved in a conventional TDMA radio communication system in that it is difficult for the base station to achieve reassignment of channels to a plurality of terminal stations at the same time with considering the entire terminal stations connected to the base station because the conventional system carries out channel assignment, changes of the assignment and reassignment individually to the terminal stations.
