The uplink transmission method according TO the third embodiment of the present invention can set multiple TOs as one or multiple TO groups when multiple TOs in one or multiple continuous slots of a PUSCH repeatedly transmit different or the same RV version of the same TB, and configure one or multiple shared DMRSs in each TO group, thereby avoiding the disadvantage of excessive DMRS overhead due TO the fact that DMRSs are configured in each TO, and effectively improving the transmission efficiency of TOs.

step S403, in the case that a DMRS exists in any TO in the TO group and at least one symbol in the any TO collides with a frame structure in a slot, shifting the DMRS set in the any TO a set TO in the TO group.

In this embodiment, a method of shifting the DMRS set in any TO a set TO in a TO group includes: and shifting the DMRS set in the any TO TO a set symbol position in a TO subsequent TO the any TO.

Optionally, the set symbol position is the same as a symbol position where the DMRS set in the any TO is located.

For example, as shown in fig. 12, in the case where DMRSs exist in T3 in a TO group (including T1, T2, T3, and T4), and at least one symbol in T3 collides with a frame structure in a slot, a TO is added (T5) after the last TO (T4) of the TO group, and data transmitted by T4 after the T3 is deferred TO a T5 transmission; the DMRS set in T3 is shifted to a set symbol position in T4 after T3.

For example, as shown in fig. 12, in the case where a DMRS exists in T3 in a TO group (including T1, T2, T3, and T4), and at least one symbol in T3 collides with a frame structure in a slot, a TO is added one after the last TO (T4) of the TO group (T5), and the DMRS set in the T3 is shifted TO a set symbol position in T5.

judging whether other TO exists after any TO in the TO group or not under the condition that the DMRS exists in any TO in the TO group and at least one symbol in the TO conflicts with a frame structure in a slot; when there is no other TO after the any TO in the TO group, it is prohibited TO offset the DMRS set in the any TO.

Step S404, when any TO in the TO group has the DMRS and at least one symbol in the TO conflicts with the frame structure in the slot, shifting the data and the DMRS in the TO TO the set TO in the TO group.

And step S405, when the DMRS exists in any TO in the TO group and at least one other symbol except the symbol where the DMRS exists in the TO conflicts with the frame structure in the slot, transmitting the existing DMRS in the TO and forbidding data transmission in the TO.

Step S406, if a DMRS exists in any TO in the TO group and a symbol in which the DMRS set in the any TO is located collides with a frame structure in the slot, shifting the DMRS set in the any TO a symbol before or after the current symbol position in which the DMRS set in the any TO is located.

In this embodiment, the symbol collision with the frame structure in the slot refers to a collision caused by collision of a symbol with the frame structure in the slot.

The uplink transmission method according TO the fourth embodiment of the present invention can set a plurality of TOs as one TO group when the plurality of TOs in one slot of the PUSCH repeatedly transmit different or the same RV version of the same TB, and configure one or more shared DMRSs in the TO group, thereby avoiding the disadvantage of excessive DMRS overhead due TO the DMRSs configured in each TO, and effectively improving the transmission efficiency of TOs; and meanwhile, under the condition that any symbol in the TO group collides with a frame structure in the slot, the DMRS is shifted, so that the normal and effective transmission of the DMRS is effectively ensured.
