TECHNICAL FIELD

The present disclosure relates to the field of communications and, in particular, to an information transmission method and device, storage medium and processor.

BACKGROUND

As the radio technology is advancing, various radio services have been emerged. However, the spectrum resources for these radio services are limited. When facing with increasing demands for bandwidth, spectrum resources between 300 MHz and 3 GHz mainly used for traditional commercial communications are extremely strained and may not satisfy requirements of future wireless communications.

The future wireless communications will use a carrier frequency (e.g., 28 GHz, 45 GHz) higher than the frequency used in a fourth generation (4G) communication system. This high frequency channel has disadvantages of large free propagation loss, easy absorption by oxygen, large attenuation caused by rain, etc., which seriously affects a coverage performance of a high-frequency communication system. In order to ensure a high-frequency communication and long-term evolution (LTE) system to have a similar signal-to-interference plus noise ratio (SINR) within a coverage area, an antenna gain of high frequency communications needs to be ensured. Fortunately, carrier frequencies for the high-frequency communications correspond to shorter wavelengths, this may ensure that more antenna elements may be accommodated per unit area; while more antenna elements may enhance the antenna gain through beamforming, thus the coverage performance of the high-frequency communications is guaranteed.

The beamforming allows a transmitting end to concentrate transmission energy to a certain direction, while energy in other directions is relatively small or none. That is to say, each beam has its own directivity, and each beam may only cover terminals on a certain direction. The transmitting end, i.e., a base station, needs to transmit multiple beams to achieve omnidirectional coverage. Typically, there are tens or even hundreds of beams. In order to satisfy access requirements that terminals may occur in all directions, an omnidirectional coverage of a system broadcast message must be realized, a communication station needs to repeatedly transmit a same system broadcast message in all beam directions. There also cause a large “absolute overhead” of the system broadcast message for the communication station.

In a new generation wireless communication system (new radio, NR), system information is divided into minimum system information (minimum SI) and other system information (other SI). The minimum system information is further divided into “main system information (MIB)” carried on a physical broadcast channel (PBCH) and “remaining minimum system information (RMSI)” carried on a physical downlink shared channel (PDSCH); the main system information is used to provide basic system parameters of a cell, and the remaining minimum system information is used to provide configuration information related to an initial access, such as, a transmission configuration of an initial access request and a receiving configuration of an initial access response message. Some other system information that needs to be broadcasted is called other system information. Different from an existing system (e.g. an LTE system), in order to achieve better forward compatibility and improve flexibility of resource scheduling, a new generation system needs to reduce transmission of always-on-line information as much as possible. Therefore, the minimum system information is broadcasted periodically, while the other system information is transmitted on demand.

However, it is still unknown how to request and transmit the other system information.
