SECONDARY SYNCHRONIZATION SEQUENCES FOR CELL GROUP DETECTION IN A CELLULAR COMMUNICATIONS SYSTEM

Abstract

Timing parameters and an identity of a particular one of a number of cell groups are indicated in a signal transmitted in a cellular communication system having a radio frame in a physical layer, the radio frame comprising a number of time slots. In a known one of the time slots, a synchronization signal, S1, is transmitted that comprises a pair of sequences, {tilde over (S)}i,{tilde over (S)}j ({tilde over (S)}i≠{tilde over (S)}j) arranged in a first ordering. In another known one of the time slots, a synchronization signal, S2, is transmitted that comprises the pair of sequences, {tilde over (S)}i,{tilde over (S)}j arranged in a second ordering. The selected pair of sequences is uniquely identified with the particular cell group, and the first ordering of the sequences is used only for transmission in the known one of the time slots, and the second ordering of the sequences is used only for transmission in said another known one of the time slots.
