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. ## Claims ### Claim 1 An information transmission method, comprising: receiving, by a terminal device, indication information sent by a network device, wherein the indication information comprises information indicating 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; and processing, by the terminal device, the at least two pieces of system information, wherein M is a positive integer greater than or equal to 2. ### Claim 2 (depends on 1) The method according to claim 1, wherein the processing, by the terminal device, the at least two pieces of system information comprises: performing, by the terminal device, combined demodulation on the at least two pieces of system information. ### Claim 3 (depends on 1) The method according to claim 1, wherein the processing, by the terminal device, the at least two pieces of system information comprises: 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. ### Claim 4 (depends on 1) The method according to claim 1, wherein the receiving, by a terminal device, indication information sent by a network device comprises: receiving, by the terminal device, a broadcast message sent by the network device, wherein the broadcast message carries the indication information. ### Claim 5 (depends on 1) The method according to claim 1, wherein the receiving, by a terminal device, indication information sent by a network device comprises: receiving, by the terminal device, control information sent by the network device, wherein the control information carries the indication information. ### Claim 6 (depends on 1) 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. ### Claim 7 (depends on 1) 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. ### Claim 8 A terminal device, comprising: a receiver, configured to: receive indication information sent by a network device, wherein the indication information comprises information indicating content of M pieces of system information; and receive the M pieces of system information sent by the network device; and a processor, 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; and process the at least two pieces of system information, wherein M is a positive integer greater than or equal to 2. ### Claim 9 (depends on 8) The terminal device according to claim 8, wherein the processor is configured to perform combined demodulation on the at least two pieces of system information. ### Claim 10 (depends on 8) The terminal device according to claim 8, wherein the processor is configured to: 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. ### Claim 11 (depends on 8) The terminal device according to claim 8, wherein the receiver is configured to receive a broadcast message sent by the network device, wherein the broadcast message carries the indication information. ### Claim 12 (depends on 8) The terminal device according to claim 8, wherein the receiver is configured to receive control information sent by the network device, and the control information carries the indication information. ### Claim 13 (depends on 8) The terminal device according to claim 8, 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. ### Claim 14 (depends on 8) The terminal device according to claim 8, 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. ### Claim 15 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 sent by a network device, wherein the indication information comprises information indicating 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; and processing, by the terminal device, the at least two pieces of system information, wherein M is a positive integer greater than or equal to 2.
