Title:
COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/161301
Kind Code:
A1
Abstract:
From among transmission signals, a superimposition terminal uses, for superimposing a superimposition signal, a reply band in which no return data is sent from a communication terminal to a transmission unit as a superimposable band suitable for superimposing superimposition signals. When a transmission receiving unit receives, in a transmission band for a transmission signal, reserve data with which the transmission unit prohibits all communication terminals from sending return data in the reply band following said transmission band, a determination unit of the superimposition terminal determines that the reply band following said transmission band is a superimposable band. The reserve data is a timing synchronization pulse that is sent by the transmission unit at fixed time intervals in transmission bands for transmission signals in order to temporally synchronize with the communication terminals.
