Title:
COMMUNICATION SYSTEM AND TRANSMISSION UNIT
Document Type and Number:
WIPO Patent Application WO/2012/057147
Kind Code:
A1
Abstract:
A transmission unit is provided with a mediation unit for assigning superimposable time periods to individual protocols such that superimposable time periods used by different groups of superimposed communication terminals for inter-terminal communication are not used for superimposition with different individual protocols. Depending on the assignment of the superimposable time periods, the mediation unit sequentially transmits from the superimposed transmission units communication permissions which permit the superimposed communication terminals of each group to perform inter-terminal communication. The superimposed communication terminals of each group start inter-terminal communication after receiving a communication permission. By this means, the superimposed communication terminals of each group transmit superimposed signals from a signal transmission unit at a timing such that the superimposed signals are superimposed during the respective superimposable time periods assigned by the mediation unit.
