Abstract
The present disclosure describes a physical random access channel (PRACH) preamble sending method. In one example method, access slot information is received by a user equipment (UE) from a controller. The received access slot information comprises a start access slot (AS) corresponding to each random access channel (RACH) sub-channel. ASs that start from the start AS and whose quantity is a quantity of PRACH preamble repetitions are used by the UE to send a same PRACH preamble. A PRACH preamble is repeatedly sent, by the UE, to a base station according to the received access slot information.
