Patent ID: 6882633

Claim:
A method for synchronizing a mobile radio receiver with a frame structure of a radio signal received from one specific base station of a plurality of base stations, the method comprises the steps of: transmitting, from each of the base stations, a predefined sequence for each frame, the predefined sequence having N frame synchronization codes selected from a set of synchronization codes, and in each case two predefined sequences transmitted by different ones of the base stations differ from one another in terms of at least one frame synchronization code; detecting and decoding the frame synchronization codes, transmitted by the specific base station, in the mobile radio receiver, the synchronization codes of the set of synchronization codes being known in the mobile radio receiver, resulting in detected and decoded frame synchronization codes; allocating a code parameter, to each of the detected and decoded frame synchronization codes, the code parameter characterizing each of the detected and decoded frame synchronization codes; identifying the predefined sequence transmitted by the specific base station on a basis of N consecutively received code parameters, resulting in an identified sequence; and synchronizing the mobile radio receiver with the frame structure of the radio signal received from the specific base station by aligning a timing of the frame structure used in the mobile radio receiver with a characteristic time of the identified sequence.
