Description

CROSS-REFERENCE TO RELATED APPLICATION The application is a national phase of International Application No. PCT/CN2020/109017, filed on Aug. 13, 2020, the entire content of which is incorporated herein by reference. TECHNICAL FIELD The disclosure relates to the field of wireless communication technologies, and particularly to, a method and a device for configuring frequency hopping, and a storage medium. BACKGROUND In communication technologies, a machine type communication (MTC) technology and a narrow band Internet of Things (NB-IoT) technology are provided for applications of IoT services such as low-rate, high-latency, or the like. In the related art, the MTC and NB-IoT technologies may not satisfy requirements of current IoT services with regard to the rate and the latency due to the ongoing development of the IoT services. Therefore, a new terminal such as a reduced capability user equipment (UE), simply referred to as an NR-lite, has been developed to cover requirements of the IoT services that require a faster rate of data transfer with reduced latency than that provided by current MTC and NB-IoT devices. A coverage enhancement means is adopted for a reduced capability problem of the terminal, and frequency-hopping transmission is further introduced. SUMMARY According to a first aspect of the disclosure, a method for configuring frequency hopping is provided. The method includes: determining a frequency-hopping related parameter; and transmitting data on at least one frequency band resource based on the frequency-hopping related parameter. According to a second aspect of the disclosure, a device for configuring frequency hopping is provided. The device includes: a processor; and a memory configured to store instructions executable by the processor; in which the processor is configured to perform the method for configuring frequency hopping in the first aspect. According to a third aspect of embodiments of the disclosure, a non-transitory computer readable storage medium is provided. When instructions in the storage medium are executed by a processor of a mobile terminal, the mobile terminal is caused to perform the method for configuring frequency hopping in the first aspect. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

DETAILED DESCRIPTION Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of embodiments do not represent all implementations consistent with the disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the disclosure as recited in the appended claims. In a communication system, MTC and NB-IoT technologies are proposed in the related art for scenarios such as low-rate and high-latency applications (such as meter reading and environmental monitoring) in IoT services. At present, the NB-IoT technology may support a maximum rate of several hundred kilobytes and the MTC technology may support a maximum rate of several megabytes. However, with ongoing development of technology services (for example, monitoring, smart home, wearable devices, and industrial sensor detection, etc.), a rate of dozens to one hundred megabytes is generally required and a requirement for latency is also increased. Therefore, in the communication system, MTC and NB-IoT technologies have not satisfied requirements of the current IoT services. Therefore, a new user equipment (UE) is designed in a new radio (NR) communication system to cover a rate of dozens to one hundred megabytes and has a service requirement of a middle-end IoT device with a hi
