A communication method performed by a base station in a wireless communication network is disclosed. The base station notifies a terminal of a cyclic shift increment NCS configuration information indicating an NCS value. The base station then receives from the terminal a random access preamble related to the NCS value indicated by the NCS configuration information. The NCS value belongs to a set of cyclic shift increments including all of the following cyclic shift increments of 0, 13, 15, 18, 22, 26, 32, 38, 46, 59, 76, 93, 119, 167, 279, and 419.
