Information transmission method, terminal device, and network device
In the information transmission method provided in this disclosure, a terminal device receives downlink control information. The downlink control information includes first information, and the first information indicates an uplink control channel resource for carrying uplink control information. The uplink control channel resource belongs to a first uplink control channel resource set, and the first uplink control channel resource set includes at least two uplink control channel resources that correspond to different quantities of symbols, or includes at least two uplink control channel resources that correspond to different quantities of resource blocks. The terminal device sends uplink control information to a network device by using the uplink control channel resource.

sending, by the terminal device, the uplink control information to a network device by using the uplink control channel resource.
2. The method according to claim 1 , further comprising:
receiving higher layer signaling; and
determining the first uplink control channel resource set based on the higher layer signaling.
3. The method according to claim 2 , wherein the determining the first uplink control channel resource set based on the higher layer signaling comprises:
determining, based on the higher layer signaling, quantities of symbols corresponding to uplink control channel resources in the first uplink control channel resource set.
4. The method according to claim 1 , wherein the first uplink control channel resource set further comprises a third uplink control channel resource that occupies seven symbols, and a fourth uplink control channel resource that occupies 14 symbols.
5. An apparatus, comprising:
a storage medium including executable instructions; and
at least one processor;
wherein the executable instructions, when executed by the at least one processor, cause the apparatus to:

determine, based on the first information, the uplink control channel resource among the at least two uplink control channel resources for carrying uplink control information; and
send the uplink control information to a network device by using the uplink control channel resource.
6. The apparatus according to claim 5 , wherein the executable instructions, when executed by the at least one processor, further cause the apparatus to:
receive higher layer signaling; and
determine the first uplink control channel resource set based on the higher layer signaling.
7. The apparatus according to claim 6 , wherein the executable instructions, when executed by the at least one processor, cause the apparatus to determine the first uplink control channel resource set as follows:
determining, based on the higher layer signaling, quantities of symbols corresponding to uplink control channel resources in the first uplink control channel resource set.
8. The apparatus according to claim 5 , wherein the first uplink control channel resource set further comprises a third uplink control channel resource that occupies seven symbols, and a fourth uplink control channel resource that occupies 14 symbols.
9. A non-transitory computer-readable storage medium comprising instructions which, when executed by a terminal device, cause the terminal device to carry out operations comprising:
receiving downlink control information, wherein the downlink control information comprises first information, the first information indicates an uplink control channel resource for carrying uplink control information, the uplink control channel resource belongs to a first uplink control channel resource set, wherein each resource in the first uplink control channel resource set occupies a different quantity of symbols, the first uplink control channel resource set comprises at least two uplink control channel resources, wherein the at least two uplink control channel resources includes a first uplink control channel resource that occupy one symbol, and a second uplink control channel resource that occupies two symbols;
determining, based on the first information, the uplink control channel resource among the at least two uplink control channel resources for carrying uplink control information; and
sending the uplink control information to a network device by using the uplink control channel resource.
10. The non-transitory computer-readable storage medium according to claim 9 , wherein the operations further comprise:
receiving higher layer signaling; and
determining the first uplink control channel resource set based on the higher layer signaling.
11. The non-transitory computer-readable storage medium according to claim 10 , wherein the determining the first uplink control channel resource set based on the higher layer signaling comprises:
determining, based on the higher layer signaling, quantities of symbols corresponding to uplink control channel resources in the first uplink control channel resource set.
12. The non-transitory computer-readable storage medium according to claim 9 , wherein the first uplink control channel resource set further comprises a third uplink control channel resource that occupies seven symbols, and a fourth uplink control channel resource that occupies 14 symbols.
