Description

CROSS-REFERENCE TO RELATED APPLICATION This application is the U.S. national application of International Application No. PCT/CN2020/103880, filed on Jul. 23, 2020, the entire disclosure of which is incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to a field of wireless communication technologies, and particularly to a method and an apparatus for processing a random access parameter, and a storage medium. BACKGROUND With continuous development and popularization of Internet of Things (IoT) services, such as video surveillance, smart home, wearable devices, industrial sensor monitoring and other services, the services usually need a rate of tens of megabytes to 100M, and also have a relatively high requirement for a delay. Therefore, machine type communication (MTC) and narrow band (NB)-IoT technologies in LTE are difficult to meet requirements. Based on this case, many companies propose a new terminal that is redesigned in 5G new radio (NR) to cover the requirement of such IoT device. In the current 3 GPP standardization, a new radio lite (NR Lite) system introduces a new terminal between a NB terminal and an NR terminal in terms of a transmission delay, a rate requirement and a terminal cost. The new terminal is referred to as a reduced capability user equipment (Redcap UE) or an NR-lite. In a known technical solution, as long as physical random access channel (PRACH) resources used by terminals for random access have the same time and the same frequency, random access responses (RARs) of the terminals may be in the same physical downlink shared channel (PDSCH), and are scheduled by the same PDCCH (RAR PDCCH). A search space carrying the scheduled random access responses (RARs) in the known NR is referred to as a type-1 PDCCH common search space (CSS), and the cyclic redundancy check (CRC) carried in the PDCCH is scrambled by a random access-radio network temporary identity (RA-RNTI). The current RA-RNTI is determined based on the following rules: RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id, where s_id is a start symbol index of the PRACH, 00≤s_id<14; t_id is a start slot index of the PRACH in a system frame, 0≤t_id<80; f_id is a frequency domain location index of the PRACH, 0≤f_id<8; and ul_carrier_id is an uplink carrier type for sending the MSG1, i.e., a message for sending a preamble sequence (0 represents a normal uplink (NUL) carrier, 1 represents a supplementary uplink (SUL) carrier). A low-capability terminal and a normal UE (normal terminal) access the network through the same synchronization signal block (SSB), and share a control channel resource set #0 (CORESET #0), and RAR PDCCHs of the low-capability terminal and the normal UE may be sent in the CORESET #0. In this way, there may be two RAR PDCCHs with the same RA-RNTI in the CORESET #0, resulting in a collision. SUMMARY According to a first aspect of the present disclosure, a method for processing a random access parameter is performed by a first type user equipment (UE). The method includes: determining a first parameter for random access of the first type UE, in which the first parameter for random access of the first type UE is not completely the same as or completely different from a second parameter for random access of a second type UE, and a type of the first type UE is different from a type of the second type UE. According to a second aspect of the present disclosure, a method for processing a random access parameter is performed by a network device. The method includes: receiving a first parameter sent by a first type user equipment (UE), in which the first parameter is configured for random access of the first type UE; in which the first parameter for random access of the first type UE is not completely the same as or completely different from a second parameter for random access of a second type UE, and a type of the first type UE is different from a type of the second type UE. According to a third aspect of the present disclosure, a first type user equipment (UE) includes: a processor; anda memory configured to store instructions executable by the processor:in which, the processor is configured to: determine a first parameter for random access of the first type UE. The first parameter for random access of the first type UE is not completely the same as or completely different from a second parameter for random access of a second type UE, and a type of the first type UE is different from a type of the second type UE.
