Data transmission method, transmitter, receiver, storage medium

A data transmission method, the method comprising:

• receiving, by a receiver, transmission signals transmitted by at least one of transmitters on a first time-frequency resource region and a second time-frequency resource region, and extracting bit sequence B and bit sequence B2 corresponding to each of the transmitters based on the transmission signals transmitted by each of the transmitters on the first time-frequency resource region and the second time-frequency resource region;
• and
• determining feedback information for each of the transmitters based on reconstructed signals of the bit sequence B and/or the bit sequence B2 corresponding to each of the transmitters, and transmitting the feedback information for each of the transmitters;
• wherein,
• the feedback information comprises at least terminal identity identification information, uplink synchronization alignment timing advance TA information, and a temporary identifier allocated to a cell where a terminal locates after contention resolution;
• or, at least comprises the terminal identity identification information, the uplink synchronization alignment timing advance TA information, the temporary identifier allocated to the cell where the terminal locates after the contention resolution, and uplink grant assigned for subsequent data of the transmitter;
• or, at least comprises the terminal identity identification information and an acknowledgement ACK/negative acknowledgement NACK;
• or, at least comprises the terminal identity identification information and the acknowledgement ACK/negative acknowledgement NACK, the temporary identifier allocated to the cell where the terminal locates after the contention resolution, and the uplink grant assigned for subsequent data of the transmitter.

A transmitter, comprising:

• a processor and a memory for storing a computer program executable on the processor, wherein, when the computer program is executed by the processor for performing a data transmission method, the method comprising:
• transmitting transmission signals, that are generated from a bit sequence B using at least a symbol spreading technology, on a first time-frequency resource region;
• wherein, a spreading sequence used by the symbol spreading technology is an Index1-th sequence in a sequence set containing K1 spreading sequences, and the Index1-th represents a first index value;
• and
• using partial bits of the bit sequence B and a bit sequence B0 as a bit sequence B2, and transmitting transmission signals generated based on the bit sequence B2 on an Index2-th sub-resource pool in a second time-frequency resource region containing K2 sub-resource pools:
• the Index2-th representing a second index value;
• wherein,
• a first index value Index1 and a second index value Index2 are both determined by the bit sequence B0;
• and the bit sequence B0 is determined according to the bit sequence B, or is determined jointly according to the bit sequence B and system parameter information associated with current transmission process.
