Abstract

Embodiments of the present application provide a transmission method and device for uplink control information. The method includes: a UE maps target uplink control information to a PUSCH, the PUSCH being transmitted through a pre-configured grant-uplink resource, the target uplink control information including first uplink control information, and the first uplink control information including control information for demodulating the PUSCH; and sends the PUSCH to a network device through the pre-configured grant-uplink resource. In the embodiments of the present application, when target uplink control information needs to be transmitted, a UE can map the target uplink control information to a PUSCH, and then sends the PUSCH through a pre-configured grant-uplink resource, thereby realizing the transmission of the target uplink control information.

First claim

What is claimed is:

1. A transmission method for uplink control information which is applied to a user equipment (UE), and the method comprises:
mapping target uplink control information to a physical uplink shared channel (PUSCH), wherein the PUSCH is transmitted through a pre-configured grant-uplink resource, the target uplink control information comprises first uplink control information, and the first uplink control information comprises control information for demodulating the PUSCH; and
sending the PUSCH through the pre-configured grant-uplink resource;
wherein mapping the target uplink control information to the PUSCH comprises:
mapping the first uplink control information from a first symbol in the PUSCH onto consecutive X symbols in the PUSCH according to a frequency domain priority principle, wherein the first symbol is a first PUSCH symbol after a first demodulation reference signal DMRS symbol in the PUSCH, and X is an integer greater than or equal to 1;

wherein the target uplink control information further comprises second uplink control information, and mapping the target uplink control information to the PUSCH comprises:
mapping the second uplink control information from a second symbol in the PUSCH onto consecutive Y symbols in the PUSCH according to the frequency domain priority principle, wherein the second symbol is a last symbol of the X symbols, and Y is an integer greater than or equal to 1.

2. The method according to claim 1 , wherein,
the first uplink control information comprises: configured grant-uplink control information (CG-UCI);
the first uplink control information does not comprise: hybrid automatic repeat request (HARQ).

3. The method according to claim 1 , wherein the second symbol is the last symbol of the X symbols, and the second uplink control information is not mapped to a resource in the second symbol that has been used to map the first uplink control information.

4. The method according to claim 1 , wherein the target uplink control information comprises second uplink control information, and the second uplink control information comprises a first channel state information part (CSI Part 1).

5. The method according to claim 4 , wherein the target uplink control information comprises third uplink control information, the second uplink control information comprises the CSI Part 1, and the third uplink control information comprises a second channel state information part (CSI Part 2).

6. The method according to claim 5 , wherein mapping the target uplink control information to the PUSCH comprises:
mapping the third uplink control information to the PUSCH, wherein when the third uplink control information is mapped to the PUSCH, the third uplink control information is neither mapped to a resource that has been used to map the first uplink control information nor to a resource that has been used to map the second uplink control information.

7. A user equipment (UE), comprising: at least one processor and a memory;
the memory stores computer execution instructions;
the at least one processor, when executing the computer execution instructions stored in the memory, is caused to:
map target uplink control information to a physical uplink shared channel (PUSCH), wherein the PUSCH is transmitted through a pre-configured grant-uplink resource, the target uplink control information comprises first uplink control information, and the first uplink control information comprises control information for demodulating the PUSCH; and
send the PUSCH through the pre-configured grant-uplink resource;
wherein the at least one processor is caused to:
map the first uplink control information from a first symbol in the PUSCH onto consecutive X symbols in the PUSCH according to a frequency domain priority principle, wherein the first symbol is a first PUSCH symbol after a first demodulation reference signal DMRS symbol in the PUSCH, and X is an integer greater than or equal to 1;

wherein the target uplink control information further comprises second uplink control information, and the at least one processor is further caused to:
map the second uplink control information from a second symbol in the PUSCH onto consecutive Y symbols in the PUSCH according to the frequency domain priority principle, wherein the second symbol is a last symbol of the X symbols, and Y is an integer greater than or equal to 1.

8. The UE according to claim 7 , wherein,
the first uplink control information comprises: configured grant-uplink control information (CG-UCI);
the first uplink control information does not comprise: hybrid automatic repeat request (HARQ).

9. The UE according to claim 7 , wherein the second symbol is the last symbol of the X symbols, and the second uplink control information is not mapped to a resource in the second symbol that has been used to map the first uplink control information.

10. The UE according to claim 7 , wherein the target uplink control information comprises second uplink control information, and the second uplink control information comprises a first channel state information part (CSI Part 1).

11. The UE according to claim 10 , wherein the target uplink control information comprises third uplink control information, the second uplink control information comprises the CSI Part 1, and the third uplink control information comprises a second channel state information part (CSI Part 2).

12. The UE according to claim 11 , wherein the at least one processor is configured to:
map the third uplink control information to the PUSCH, wherein when the third uplink control information is mapped to the PUSCH, the third uplink control information is neither mapped to a resource that has been used to map the first uplink control information nor to a resource that has been used to map the second uplink control information.

13. A network device, comprising: at least one processor and a memory;
the memory stores computer execution instructions;
the at least one processor, when executing the computer execution instructions stored in the memory, is caused to:
receive a physical uplink shared channel (PUSCH) sent by a user equipment (UE) through a pre-configured grant-uplink resource, wherein the PUSCH is mapped with target uplink control information, the target uplink control information comprises first uplink control information, and the first uplink control information comprises control information for demodulating the PUSCH;
wherein the first uplink control information is mapped from a first symbol in the PUSCH onto consecutive X symbols in the PUSCH according to a frequency domain priority principle, wherein the first symbol is a first PUSCH symbol after a first demodulation reference signal (DMRS) symbol in the PUSCH, and X is an integer greater than or equal to 1;
