Claim 3:
4. The method of claim 1, wherein the first position occupied by the physical random access channel sequences sent in the first physical resource configuration pattern in the frequency domain bandwidth comprises:
at least two frequency domain units, wherein the at least two frequency domain units are in a one-to-one correspondence with the physical random access channel sequences, and the physical random access channel sequence sent in each frequency domain unit is repeated;
wherein the at least two frequency domain units are in an axisymmetric pattern according to a symmetry axis, and transmission positions of the physical random access channel sequences in the at least two frequency domain units are aligned on both sides, in the center or on one side according to the symmetry axis.
