Abstract  Abstract

And signal sending in honeycomb communication system and the indication of the time parameter and mark honeycomb communication system the specific cell group in multi-cell group comprises one wireless frame and in physical layer the wireless frame comprises two multi-time slot. Sending synchronization signal S1 on one of known in these time slot of time slot the synchronization signal S1 comprises according to the first order and one row for sequence (I). Sending synchronization signal S2 in another one of known at these time slot of time slot the synchronization signal S2 comprises the second sequence according to arrangement of said one sequence for (II). In one sequence for the selection of the specific cell group of unique identifier out of the first sequence and the sequence is only used for one of the known at these time slot and the time slot for sending then the second sequence the sequence is only used for another one in two known at these time slot and the time slot for sending.

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.
