Abstract

The invention provides an information transmission method, device and equipment, and the method is executed by environment Internet of Things equipment, and comprises the steps: determining the frequency domain position of D2R uplink transmission according to the frequency domain configuration information of the D2R uplink transmission and a frequency hopping mode of the D2R uplink transmission; sending D2R uplink information to the first device according to the frequency domain position; the D2R uplink transmission frequency hopping mode comprises at least one of the following items: frequency hopping is used for a plurality of D2R uplink transmissions in the response associated to the downlink signaling carried by the R2D link for one time; frequency hopping is used for D2R uplink transmission in the response of the downlink signaling which is associated to the R2D link for multiple times; and frequency hopping is used for multiple repeated transmissions corresponding to one D2R uplink transmission. According to the scheme, the frequency domain position of the D2R uplink transmission is determined according to the frequency domain configuration information of the D2R uplink transmission and the frequency hopping mode of the D2R uplink transmission, and then the D2R uplink information is sent to the first device according to the frequency domain position, so that frequency hopping transmission of the D2R uplink transmission can be realized, and the performance of the D2R uplink transmission is improved.
