Data transmission method and apparatus

A terminal device, comprising:

• a processor;
• and
• a computer readable storage medium storing programming for execution by the processor, the programming including instructions to carry out a method comprising:
• receiving a first resource configuration from a network device, wherein the first resource configuration is used to indicate a first resource, and the first resource is used by the terminal device to send data when the terminal device is in an idle mode, wherein the first resource configuration includes a parameter indicating a time domain position and/or a frequency domain position of the first resource, and the first resource configuration further includes one or more of a repetition number of the first resource, a first cell radio network temporary identity of the terminal device, an RRC configuration that is used for data bearer establishment and/or access stratum AS security processing, or a periodic configuration of the first resource;
• when the terminal device is in the idle mode and has to-be-sent first uplink data, sending, the first uplink data to the network device on the first resource;
• wherein the first resource configuration is further used to indicate a second resource, if the terminal device fails to send the first uplink data on the first resource, sending, by the terminal device, the first uplink data on the second resource.

• the first resource is used to transmit uplink data first and the second resource is used to transmit uplink data after transmitting first uplink data via the first resource fails;
• receiving first uplink data from the terminal device on the first resource or on the second resource.
