Information transmission method, terminal device, and network device
Embodiments of this application provide an information transmission method, a terminal device, and a network device. The method includes: receiving, by the terminal device, indication information sent by the network device, where the indication information includes information used to indicate content of M pieces of system information; receiving, by the terminal device, the M pieces of system information sent by the network device; determining, by the terminal device, at least two pieces of system information with same content in the M pieces of system information based on the indication information.
1. An information transmission method, comprising:
receiving, by a terminal device, indication information from a network device, wherein the indication information comprises information indicating content of M pieces of system information, and M is a positive integer greater than or equal to 2;
receiving, by the terminal device, the M pieces of system information from the network device;
determining, by the terminal device, at least two pieces of system information with same content in the M pieces of system information based on the indication information;
demodulating, by the terminal device, first system information in the at least two pieces of system information; and
skipping demodulating system information other than the first system information in the at least two pieces of system information.
2. The method according to claim 1 , wherein the receiving, by a terminal device, indication information from a network device comprises:
receiving, by the terminal device, a broadcast message from the network device, wherein the broadcast message carries the indication information.
3. The method according to claim 1 , wherein the receiving, by a terminal device, indication information from a network device comprises:
receiving, by the terminal device, control information from the network device, wherein the control information carries the indication information.
4. The method according to claim 1 , wherein
the information indicating the content of the M pieces of system information comprises at least one of the following:
a resource identifier corresponding to each of the M pieces of system information, a resource group identifier corresponding to each of the M pieces of system information, or a content identifier corresponding to each of the M pieces of system information.
5. The method according to claim 1 , wherein
the at least two pieces of system information are in a same system information transmission period; or
the at least two pieces of system information are in at least two system information transmission periods.
6. An apparatus, comprising:
a receiver, configured to:
receive indication information from a network device, wherein the indication information comprises information indicating content of M pieces of system information, and M is a positive integer greater than or equal to 2; and
receive the M pieces of system information from the network device; and
one or more processors, configured to:
determine at least two pieces of system information with same content in the M pieces of system information based on the indication information;
demodulate first system information in the at least two pieces of system information; and
skip demodulating system information other than the first system information in the at least two pieces of system information.
7. The apparatus according to claim 6 , wherein
the receiver is configured to receive a broadcast message from the network device, wherein the broadcast message carries the indication information.
8. The apparatus according to claim 6 , wherein
the receiver is configured to receive control information from the network device, and the control information carries the indication information.
9. The apparatus according to claim 6 , wherein
the information indicating the content of the M pieces of system information comprises at least one of the following:
a resource identifier corresponding to each of the M pieces of system information, a resource group identifier corresponding to each of the M pieces of system information, or a content identifier corresponding to each of the M pieces of system information.
10. The apparatus according to claim 6 , wherein
the at least two pieces of system information are in a same system information transmission period; or
the at least two pieces of system information are in at least two system information transmission periods.
11. A non-transitory computer-readable storage medium storing computer instructions, that when executed by one or more hardware processors, cause the one or more hardware processors to perform operations comprising:
receiving, by a terminal device, indication information from a network device, wherein the indication information comprises information indicating content of M pieces of system information, and M is a positive integer greater than or equal to 2;
receiving, by the terminal device, the M pieces of system information from the network device;
determining, by the terminal device, at least two pieces of system information with same content in the M pieces of system information based on the indication information;
demodulating, by the terminal device, first system information in the at least two pieces of system information; and
skipping demodulating system information other than the first system information in the at least two pieces of system information.
12. The non-transitory computer-readable storage medium according to claim 11 , wherein the receiving, by a terminal device, indication information from a network device comprises:
receiving, by the terminal device, a broadcast message from the network device, wherein the broadcast message carries the indication information.
13. The non-transitory computer-readable storage medium according to claim 11 , wherein the receiving, by a terminal device, indication information from a network device comprises:
receiving, by the terminal device, control information from the network device, wherein the control information carries the indication information.
14. The non-transitory computer-readable storage medium according to claim 11 , wherein the information indicating the content of the M pieces of system information comprises at least one of the following:
a resource identifier corresponding to each of the M pieces of system information, a resource group identifier corresponding to each of the M pieces of system information, or a content identifier corresponding to each of the M pieces of system information.
15. The non-transitory computer-readable storage medium according to claim 11 , wherein the at least two pieces of system information are in a same system information transmission period.
16. The non-transitory computer-readable storage medium according to claim 11 , wherein the at least two pieces of system information are in at least two system information transmission periods.
