METHOD OF SEQUENCE ASSIGNMENT AND DEVICE FOR SEQUENCE ASSIGNMENT Russian patent published in 2011 - IPC H04J11/00 

FIELD: information technologies.

SUBSTANCE: method to assign a sequence and a device to assign a sequence are used in a system, where multiple different Zadoff-Chu sequences or GCL sequences are assigned to one cell, at the same time a number of arithmetic operations and extent of correlation circuit integration at a receiving end may be reduced. According to these method and device, at ST201 a counter (a) and a number (p) of current assignments of a sequence are initialised, and at ST202 it is identified whether the number (p) of current sequence assignments matches the number (K) of assignments to one cell. At ST203 it is identified whether the number (K) of assignments to one cell is odd or even. If K is even, at ST204-ST206, numbers of sequences (r=a and r=N-a), which are currently not assigned, are combined and then assigned. If K is odd, at ST207-ST212, for those sequences, to which a pair may not be selected, one of sequence numbers (r=a and r=N-a) is assigned, which are currently not assigned.

EFFECT: reduced volume of calculations.
