Message transmission method, user device, base station, and computer storage medium

A message transmission method, applied to an Evolved Node B (eNB), comprising:

• generating Uplink (UL) grant information for User Equipment (UE);
• determining a serial number of a Downlink (DL) sub-frame for sending the UL grant information or retransmission indication information, determining at least one corresponding sub-frame delay corresponding to the serial number of the DL sub-frame 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
• sending the UL grant information or the retransmission indication information to the UE in the DL sub-frame and receiving, in the at least one UL resource, UL shared channel transmission sent from the UE, wherein the UE performs the following steps:
• determining the at least one UL resource on the basis of the at least one sub-frame delay 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.

User Equipment (UE), comprising a processor and a memory configured to store a computer program capable of being run on the processor,

• wherein the processor is configured to run the computer program to execute steps of a message transmission method, comprising:
• receiving Uplink (UL) grant information or retransmission indication information sent from an Evolved Node B (eNB) side;
• determining at least one corresponding 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 the processor is further configured to:
• when the determined UL resource is the UpPTS of the special sub-frame,
• calculate a number of Physical Resource Blocks (PRBs) allocated in the UpPTS and calculate 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
• search a data block size index on the basis of a modulation and coding scheme index and calculate a value of the number of UL data blocks on the basis of the equivalent number of PRBs and the data block size index.
