Abstract
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, 419.

2. The communication method according to claim 1, further comprising:
determining a time advance in accordance with the random access preamble; and
transmitting the time advance to the terminal.
3. The communication method according to claim 1, further comprising:
sending a downlink synchronization signal to the terminal to get downlink synchronized with the terminal.
4. The communication method according to claim 1, wherein the NCS value of 0 in the set of cyclic shift increments represents one preamble sequence is generated from one root sequence.
5. The communication method according to claim 4, wherein the NCS value of 0 in the set of cyclic shift increments represents a same cyclic shift as an NCS value of 839.

7. The communication method according to claim 6, wherein the set of random access preambles is derived from at least one Zadoff-Chu sequence.
8. The communication method according to claim 7, wherein the at least one Zadoff-Chu sequence is used in generation of a sequence xu,v(k) for the set of random access preambles, the sequence xu,v(k) is given by:
xu,v(k)=xu((k+vNCS) mod NZC), where u and v are integers, NZC is a length of the at least one Zadoff-Chu sequence.
9. The communication method according to claim 7, wherein random access preambles derived from a same Zadoff-Chu sequence in the set of random access preambles being with zero correlation zones of length NCS?1.
10. The communication method according to claim 7, wherein the number of preambles derived from a single root sequence is Npre=?NZC/NCS?, and NZC is the length of the Zadoff-Chu sequence.
11. The communication method according to claim 6, wherein the number of random access preambles in the set of random access preambles is 64.
12. The communication method according to claim 1, wherein non-zero cyclic shift increments NCS(k) in the set of cyclic shift increments are derived in accordance with the following formula:
N CS(k)=?N ZC/[N pre(0)�a k +a/(1?a)�(a k?1)]?, k=0,1,2 . . . K;
wherein ? ? denotes a rounding down operation, ? ? denotes a rounding operation, a=0.856, Npre(0)=64, NZC=839, and K=14.
