METHOD FOR SUB-FRAME ID AND FRAME BOUNDARY DETECTION IN LONG TERM EVOLUTION (LTE) SYSTEMS

摘要

The invention relates to communication protocols and more particularly to communication protocols in Line Terminal Equipment (L TE). The different detection protocols available for radio fram..e timing detection are: Synchronization Channel (SCH) based detection; Broadest Channel (BCH) based detection, and Reference signal-based detection. The present invention provides a unique way of identifying the Frame boundaries in multiple identical/ non identical SCH's in different sub-frames via the use of a new method called "sub frame position difference method", The method implements the use of the differences between the different sub frames carried by the SCH. The sub frame identity and hence the frame boundary can be identified by calculating the difference between the positions (based on time or number of slots/ sub-frames or any data packets) of the two subsequent slots/ sub-frames or any data packets which may be even identical to each other.
