Patent ID: 8400905

Claim:
A method of transmitting a Multicast Broadcast Single Frequency Network (MBSFN) primary synchronization channel frame, said method comprising: transmitting (S 1 ) a primary synchronization code, denoted C psc,new , in predetermined time slots of a primary synchronization channel frame, where C psc,new has the following properties: C psc,new is a hierarchical Golay sequence constructed by two constituent sequences x 1,new and x 2,new , each of length 16 chips, in accordance with: y ( i )= x 2,new ( i mod 16)* x 1,new ( i div 16), i= 0 . . . 255 C psc,new =p* y (0), y (1), . . . , y (255) where x 1,new is a Golay complementary sequence to a corresponding constituent sequence x 1 = 1,1,1,-1,-1,1,-1,-1,1,1,1,-1,1,-1,1,1 for generating the primary synchronization code for non-MBSFN capable WCDMA, x 2,new is a sequence that is orthogonal to both a corresponding constituent sequence x 2 = 1,1,1,1,1,1,-1,-1, 1,-1,1,-1,1,-1,-1,1 for generating the primary synchronization code for non-MBSFN capable WCDMA and a constituent sequence b = 1,1,1,1,1,1,-1,-1,-1,1,-1,1,-1,1,1,-1 for generating the secondary synchronization codes for non-MBSFN capable WCDMA, and p denotes a phase rotation represented by a complex number; and transmitting a primary synchronization code used in non-MBSFN capable WCDMA in any remaining time slots of the frame.
