1. A message transmission method, applied to User Equipment (UE), comprising:

  • receiving Uplink (UL) grant information or retransmission indication information sent from an Evolved Node B (eNB) side;

    determining at least one sub-frame delay corresponding to a serial number of a Downlink (DL) sub-frame containing the UL grant information or the retransmission indication information, and determining at least one UL resource on the basis of the at least one sub-frame delay, the UL resource being an Uplink Pilot Time Slot (UpPTS) in a special sub-frame or being a UL sub-frame and a UpPTS in a special sub-frame; and

    performing UL shared channel transmission in the at least one UL resource;

    wherein determining the at least one UL resource on the basis of the at least one sub-frame delay further comprises;

    when the determined UL resource is the UpPTS of the special sub-frame,calculating a number of Physical Resource Blocks (PRBs) allocated in the UpPTS and calculating an equivalent number of PRBs corresponding to the number of PRBs, the equivalent number of PRBs being a product of the number of PRBs and a preset coefficient; and

    searching a data block size index on the basis of a modulation and coding scheme index and calculating a value of the number of UL data blocks on the basis of the equivalent number of PRBs and the data block size index.
