1. A data transmitting method, applicable to a UE, the method comprising:
determining, for a uplink data transmission of a random access, a data resource corresponding to a preamble in the uplink data transmission according to a correspondence relationship between preambles and data resources as specified in a protocol, wherein different preambles correspond to different data resources; and
transmitting the preamble, and uplink data on determined data resource;
wherein the data resource comprises:
a time resource occupied by data, a frequency resource occupied by data, a DeModulation Reference Signal (DMRS) of data, and a spreading code of data;
wherein if the data resource is the DMRS of data, the determining the data resource corresponding to the preamble in the uplink data transmission according to the correspondence relationship between preambles and data resources, as specified in the protocol comprises:
determining the DMRS corresponding to the preamble in the uplink data transmission according to a correspondence relationship between preamble groups, and DMRS's of data, as specified in the protocol, and the preamble in the uplink data transmission, wherein each of the preamble groups comprises at least one preamble; and
the transmitting the uplink data on the determined data resource comprises:
transmitting the uplink data encoded and modulated using determined DMRS;
if the data resource is the spreading code of data, the determining the data resource corresponding to the preamble in the uplink data transmission according to the correspondence relationship between preambles and data resources, as specified in the protocol comprises:
determining the spreading code corresponding to the preamble in the uplink data transmission according to a correspondence relationship between preamble groups, and spreading codes of data, as specified in the protocol, and the preamble in the uplink data transmission, wherein each of the preamble groups comprises at least one preamble; and
the transmitting the uplink data on the determined data resource comprises:
transmitting the uplink data spread using determined spreading code.
