摘要： Provided are a data transmission method, apparatus and computer readable storage medium. The method includes: sending, by a terminal, a random access preamble to a base station, and receiving, by the terminal, a random access response sent by the base station; and sending, by the terminal, a first request message carrying uplink data to the base station; wherein the sending, by the terminal, the random access preamble to the base station comprises: in response to determining that the terminal satisfies a first preset condition, sending, by the terminal, the random access preamble for requesting an uplink data transmission resource to the base station; and wherein the method further comprising one of: failing to receive, by the terminal, a second response message returned by the base station; receiving, by the terminal, the second response message carrying an uplink data failure indication or an uplink data retransmission indication returned by the base station; or in response to determining that the terminal fails to receive the random access response returned by the base station, determining, by the terminal, a random access failure and reinitiating, by the terminal, random access.

摘要： Disclosed are a data transmission method and apparatus, a search space optimization method and apparatus and a storage medium. The data transmission method includes that a UE sends a random access preamble to a base station and receives a random access response sent by the base station, the UE sends a first request message to the base station, and the UE in a first state receives an uplink grant sent by the base station and sends uplink data to the base station by using the uplink grant, where the first state includes an idle state or an inactive state. The UE can transmit uplink data without entering a connected state so that power consumption of the UE is reduced.
