1. A method for configuring random access resource, applied to a base station, comprising:
configuring a physical uplink shared channel occasion (PO) resource pool required for data transmission and associated with preambles transmitted on all random access channel occasions (ROs) in each same time domain or all ROs in each same random access channel (RACH) slot in each RACH period, wherein the PO resource pool comprises one or more data transmission resource POs;
performing consecutive mapping between preambles on each RO and POs in the PO resource pool; and
in response to remaining POs in the PO resource pool being insufficient to map all preambles transmitted on the ROs, configuring the remaining POs as invalid POs to which preambles are no longer mapped.
