Method of communication between a plurality of remote units and a control unit

Abstract

A the base station multiple (10) and asynchronous remote operation units (20, 22, 24, 26 and 28) and communication system, an and each remote intercell method between of which is a base depots, comprising a remote unit transmits the (208) first mode to the base station unit stochastically. The detection to the receiving of the discrepancy mode spliced, the base station unit in the window controller (234) ACK immediately. Detection in corresponding earliest with a window to the ACK remote unit and uses unit, and a rear for performing a hole (218) and a base station. The remote unit continue monitoring (214) is belong to first group of command the transmission of commands, the device according to the point comprises a static), the device for with a selected from a circuit is transmitted to the first mode to the base station unit stochastically.

The invention relates to a communication system comprising a base station (10) and a plurality of asynchronously operating remote units (20, 22, 24, 26 and 28), and in particular a method involves communication between the base station and each of the remote units which comprises each remote unit transmitting randomly (208 ) a first bit pattern to the base station. Upon detecting the reception of a faultless bit pattern, the base unit (234) transmits an ACK pulse during a first time window. The remote unit, which detects the ACK pulse during a corresponding first time window, becomes the selected unit and then (218) communicates with the base station. All other remote units continue to monitor (214) for transmission of a command belonging to a first set of commands, after which the selected unit enters a silent mode and the unselected units continue their random transmission of the first bit pattern to the base unit.
