Transmission method and apparatus, internet of things device, and electronic device

A transmission method, wherein the method comprises:

• sending, by a first device, a first downlink message to a target internet of things device, wherein the first downlink message indicates at least one internet of things device to initiate a random access procedure;
• and
• the first downlink message comprises at least one of the following:
• identification information of the at least one internet of things device;
• a paging cause;
• access procedure information, wherein the access procedure information indicates a random access type to be used by the target internet of things device;
• data transmission information, wherein the data transmission information indicates a data transmission mode used by the target internet of things device;
• access resource configuration information for the target internet of things device;
• time control information, wherein the time control information indicates retransmission occasion for the target internet of things device;
• retransmission resource configuration information for the target internet of things device;
• security information, wherein the security information is used to perform authentication on the target internet of things device, and encrypt or decrypt transmitted data;
• or
• a first indication, wherein the first indication indicates backoff time for data retransmission of the target internet of things device.

An internet of things device, comprising a processor and a memory, wherein the memory stores a program or instructions executable on the processor, and when the program or the instructions are executed by the processor, the steps of a transmission method are implemented,

• wherein the method comprises:
• receiving, by a target internet of things device, a first downlink message sent by a first device, wherein the first downlink message indicates at least one internet of things device to initiate a random access procedure;
• and
• the first downlink message comprises at least one of the following:
• identification information of the at least one internet of things device;
• a paging cause;
• access procedure information, wherein the access procedure information indicates a random access type to be used by the target internet of things device;
• data transmission information, wherein the data transmission information indicates a data transmission mode used by the target internet of things device;
• access resource configuration information for the target internet of things device;
• time control information, wherein the time control information indicates a retransmission occasion for the target internet of things device;
• retransmission resource configuration information for the target internet of things device;
• security information, wherein the security information is used to perform authentication on the target internet of things device, and encrypt or decrypt transmitted data;
• or
• a first indication, wherein the first indication indicates backoff time for data retransmission of the target internet of things device.
