Claim:
1. A random access response receiving method, comprising: receiving random access indication information, wherein the random access indication information comprises a dedicated random access preamble, a physical random access channel to be used to send the dedicated random access preamble, and a serving cell where the physical random access channel is located; sending the dedicated random access preamble to a network side on a corresponding physical random access channel according to the random access indication information; detecting control signaling masked on a physical downlink control channel, the control signaling being detected using a pre-obtained dedicated identifier, wherein the dedicated identifier is a user equipment-specific temporary identifier configured by the network side for the user equipment and wherein the control signaling comprises information about a physical downlink shared channel used to send a random access response and information required for decoding the random access response; starting a random access response receiving timer after sending the dedicated random access preamble; retransmitting the dedicated random access preamble to the network side in response to the control signaling not being detected correctly or the control signaling whose value of a carrier/cell indicator field is a reserved value not being detected correctly before timeout of the random access response receiving timer; and receiving the random access response on a corresponding physical downlink shared channel according to the control signaling.
