Abstract  Abstract

A signal transmission in a cellular communication system for indicating a timing parameter of a mark a cellular communication system a particular cell in the plurality of cell groups is provided with wireless frame in the physical layer a wireless frame comprises a number of time slots. Sending synchronous signal S1 at a known time the time the synchronous signal S1 includes a pair of series arranged according to a sequence whose structure is as formula (I). Sending synchronous signal S2 at the other end of the first known time the time the synchronous signal S2 includes the pair of received sequences (II are arranged in the second sequence). In the first sequence of the selected mark and the first sequence of the sequence only for a known time slot in the time slot according to the specific cell group only is carried out and the second sequence in order for only the other one known time slot in the time slot to transmit.

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 S

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 (I) 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 (II) arranged in a second ordering. The selected pair of sequences is uniquely ident ified 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.
