Patent ID: 7133424

Claim:
A method for synchronizing a mobile radio receiver with a time slot structure of a radio signal obtained from a base station, the method which comprises: in each of a plurality of time slots, using the base station to send out a time slot synchronization code sequence that is known in the mobile radio receiver, the time slot synchronization code sequence including a predetermined sequence of data elements; and in the mobile radio receiver: dividing the period corresponding to the one time slot synchronization code sequence into two or more time intervals, each time interval containing a portion of the time slot synchronization code sequence; during a first time slot period, detecting a first portion of the time slot synchronization code sequence, obtaining a first result by correlating the first portion of the time slot synchronization code sequence that is detected with a known time slot synchronization code sequence, during a second time slot period, detecting a second portion of the time slot synchronization code sequence, obtaining a second result by correlating the second portion of the time slot synchronization code sequence that is detected with the known time slot synchronization code sequence, and determining a time slot position in time from the first result and the second result.
