Data transmission method for multiplexing data portion, device, and system

A data transmitting method, applicable to an eNB, the method comprising:

• receiving a preamble in uplink data transmission, and uplink data;
• and
• determining a data resource corresponding to the preamble in the uplink data transmission according to the preamble, and a correspondence relationship between preambles and data resources, as specified in a protocol, and obtaining the uplink data using the data resource, wherein different preambles correspond to different data resources;
• 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 preamble, and the correspondence relationship between preambles and data resources, specified in the protocol includes:
• 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;
• 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 preamble, and the correspondence relationship between preambles and data resources, as specified in the protocol includes:
• 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.

A data transmitting device, applicable to a UE, the data transmitting device comprising:

• a memory configured to store a computer readable program, and a processor configured to read the memory to execute the computer readable program to:
• to determine, for 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
• to transmit the preamble, and uplink data using 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 the processor is configured to read the memory to execute the computer readable program to determine 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
• transmit the uplink data encoded and modulated using determined DMRS.
