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.
Claims26
A communication method performed by a base station in a wireless communication network, comprising:
- notifying a terminal of a cyclic shift increment NCS configuration information indicating an NCS value, which 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, wherein the NCS value indicates a length of Zero Correlation Zones of a random access preamble is NCS−;
- and
- receiving from the terminal the random access preamble with Zero Correlation Zones of length NCS−1.
A base station operable to communicate in a wireless communications network, the base station comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the processor coupled to the storage medium, the programming including instructions that direct the base station to:
- notify a terminal of a cyclic shift increment NCS configuration information indicating an NCS value, which 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, wherein the NCS value indicates a length of Zero Correlation Zones of a random access preamble is NCS−1;
- and
- receive from the terminal the random access preamble with Zero Correlation Zones of length NCS−1.
