TECHNICAL FIELD The disclosure relates to a field of wireless communication technologies, in particular to an information transmission method, an information transmission apparatus, a communication device and a storage medium. BACKGROUND In a wireless communication LTE 4G system, in order to support Internet of Things (IoT) services, a machine type communication (MTC) technology and a narrow band Internet of Things (NB-IoT) technology are proposed. These two technologies are mainly for low-rate and high-latency scenarios. With the continuous development of IoT services, such as population of services such as video monitoring, smart home, wearable devices and industrial sensing monitoring, these services usually require a transmission rate ranging from tens of Mbps to 100 Mbps, and the above services also have relatively high requirements for latency, thus the MTC technology and the NB-IoT technology in the LTE can hardly satisfy the requirements of the above services. Based on this case, designing a new user equipment (UE) in the 5G new radio (NR) is proposed by many companies to cover the requirements of such IoT devices. In the current 3rd Generation Partnership Project (3GPP) standardization, this new UE is called a reduced capability (Redcap) UE or simply referred to a NR-lite. SUMMARY According to a first aspect of the disclosure, an information transmission method, performed by a base station, is provided. The method includes: obtaining a status of an initial bandwidth part (BWP) of a Redcap UE; andsending at least one of a first system information block (SIB) or a second SIB according to the status of the initial BWP, in which the first SIB is an SIB that is able to be read by a current general-purpose UE, and the second SIB is an SIB exclusive to the Redcap UE. According to a second aspect of the disclosure, a communication device is provided. The communication device includes a transceiver, a memory, and a processor connected to the transceiver and the memory, respectively. The processor is configured to perform the method according to the first aspect of the disclosure. According to a third aspect of the disclosure, a non-transitory computer-readable storage medium having computer executable instructions stored thereon is provided. When the computer executable instructions are executed by a processor, the processor is caused to perform the method according to the first aspect of the disclosure.
