AI Technical Summary
Technical Problem
The current IoT-NTN protocol superframe configuration is incompatible with the TDD mode cycle, resulting in poor data transmission stability.
Method used
By receiving a narrowband secondary synchronization signal in the first transmission cycle to indicate the offset time domain resources in the second transmission cycle, the main information block is obtained, thereby ensuring the stability of data transmission between the terminal and the network device.
Benefits of technology
It enhances the stability of data transmission between terminals and network devices and resolves synchronization issues caused by incompatibility in superframe configurations.

Abstract
The present application relates to the field of communications. Provided are a communication method and apparatus. The communication method comprises: a terminal first receiving at least one first narrowband secondary synchronization signal within a first transmission period, wherein the at least one first narrowband secondary synchronization signal is used for indicating the acquisition of a master information block after a time domain resource is offset within a second transmission period; and then acquiring the master information block within the second transmission period on the basis of the at least one first narrowband secondary synchronization signal. Within a first transmission period, a terminal receives from the terminal at least one first narrowband secondary synchronization signal used for indicating the acquisition of a master information block after a time domain resource is offset within a second transmission period. In this way, the terminal can acquire the primary information block after the time domain resource is offset within the second transmission period, thereby correctly receiving the master information block, and enhancing the stability of data transmission between the terminal and a network device.
