1. A method for determining an RA-RNTI, comprising:
determining, by a terminal, a Random Access-Radio Network Temporary Identifier, RA-RNTI, according to time-frequency resources occupied by a random access preamble sequence, wherein the time-frequency resources are time-frequency resources in Orthogonal Frequency Division Multiplexing, OFDM, symbol level;
receiving, by the terminal, a random access response message transmitted by a base station, and descrambling downlink control information contained in the random access response message by using the RA-RNTI.
