Claim Text:
1. A method for transmitting data, comprising: receiving, by a communication equipment, a time-frequency resource and a corresponding relationship between a physical random access feedback channel and a physical random access channel which are sent by a base station through system broadcast on a downlink resource, wherein the time-frequency resource is a time-frequency resource on which the communication equipment sends any one preamble to the base station on the physical random access channel, and the downlink resource is a dedicated resource of the communication equipment which is indicated by the base station through a physical broadcast channel; sending, by the communication equipment, the any one preamble to the base station on the time-frequency resource, and then receiving random access feedback information sent by the base station on the physical random access feedback channel corresponding to the physical random access channel, wherein the physical random access feedback channel is obtained by the communication equipment according to the corresponding relationship between the physical random access feedback channel and the physical random access channel; performing, by the communication equipment, synchronization with time of the base station through a timing advance (TA) carried in the random access feedback information, and then sending a radio resource control (RRC) connection request message to the base station on a time-frequency resource biased with a preset time; and receiving, by the communication equipment, an RRC establishment message sent by the base station on a downlink data channel in the downlink resource, and then establishing an RRC connection with the base station.
