1. A data transmission method, comprising:
in a case where a terminal is in a connected state, receiving, by the terminal, a physical downlink control channel command sent by a base station, acquiring an non-competitive resource allocated to the terminal by the base station from the physical downlink control channel command, initiating a random access by using a random access preamble corresponding to the non-competitive resource; and
receiving, by the terminal, a random access response sent by the base station, and in response to determining that the random access response carries indication information for simultaneously sending downlink data, receiving, by the terminal, the downlink data;
wherein the method further comprises: in response to determining that the indication information indicates to carry a radio resource control (RRC) message at the time of sending a first request message, sending, by the terminal, the first request message carrying the RRC message to the base station;
in response to determining that the terminal fails to receive the random access response sent by the base station, determining, by the terminal, a random access failure and reinitiating a random access;
wherein reinitiating, by the terminal, the random access comprises: determining, by the terminal, to select one of a random access preamble for requesting an uplink data transmission resource or a random access preamble not for requesting an uplink data transmission resource to perform the random access according to at least one of: a number of random access failures, a serial number of each random access failure; a downlink measurement obtained by the terminal; a coverage level; or a number of repetitions;
in response to determining to select one of a random access preamble for requesting an uplink data transmission resource or a random access preamble not for requesting an uplink data transmission resource to perform the random access according to a number of repetitions, the number of repetitions is configured by the base station.
