Radio communication method,device and system

摘要

A synchronising method for a communication system, wherein the communication system comprises a master device and a slave device, and the communication system supports a plurality of types of links between the master device and the slave device, a first one of the types of links comprising asynchronous connectionless links and a second one of the types of links comprising synchronous connection-oriented links; the method comprising implementing synchronisation using a combination of the asynchronous links and the synchronous links. Implementation in a Bluetooth system is described. Use of a chirp signal as a timing signal is described. A communications unit and system in which the method may be employed are also described.
