Hybrid automatic repeat request harq transmission method and related device

A terminal, comprising:

• a processor, a memory, and a transceiver, wherein:
• the transceiver transmits and receives data under a control of the processor, the memory stores a preset program, and the processor reads and executes the program in the memory:
• to maintain an HARQ entity on the basis of cell, wherein the HARQ entity supports multiple concurrent HARQ processes;
• to receive scheduling signaling transmitted by a network-side device through the transceiver;
• and
• to determine an HARQ process number of the HARQ entity related to the scheduling signaling, and a baseband parameter and/or a transmission time interval corresponding to the HARQ process number according to the scheduling signaling.

A network-side device, comprising:

• a processor, a memory, and a transceiver, wherein:
• the transceiver transmits and receive data under the control of the processor, the memory stores preset program, and the processor reads and executes the program in the memory:
• to maintain an HARQ entity on the basis of each aggregated cell of a terminal, wherein the HARQ entity supports multiple concurrent HARQ processes;
• and
• to transmit scheduling signaling to the terminal through the transceiver so that the terminal determines an HARQ process number of the HARQ entity related to the scheduling signaling, and a baseband parameter and/or a transmission time interval corresponding to the HARQ process number according to the scheduling signaling.
