A device for dividing short Transmission Time Intervals (TTIs) of a special subframe, comprising:

• a first division module, configured to:
• in a case that a configuration of a special subframe having a normal cyclic prefix (CP) is used in downlink, and a Downlink Pilot Time Slot (DwPTS) of the special subframe is used for short TTI transmission, divide short TTIs in the DwPTS based on a predefined division pattern of short TTIs in a case that based on the configuration of the special subframe having the normal CP used in downlink and based on a length of a control region in the DwPTS, the DwPTS is determined to satisfy a division condition corresponding to the predefined division pattern of short TTIs.

A device for dividing short Transmission Time Intervals (TTIs) of a special subframe, comprising:

• a processor, a storage, and a transceiver, wherein the storage is configured to store programs and data used by the processor when the processor performs operations, and when the processor invokes and performs the programs and the data stored in the storage, the processor performs following steps:
• in a case that a configuration of a special subframe having a normal cyclic prefix (CP) is used in downlink, and a Downlink Pilot Time Slot (DwPTS) of the special subframe is used for short TTI transmission, dividing short TTIs in the DwPTS based on a predefined division pattern of short TTIs in a case that based on the configuration of the special subframe having the normal CP used in downlink and based on a length of a control region in the DwPTS, the DwPTS is determined to satisfy a division condition corresponding to the predefined division pattern of short TTIs;
• wherein the transceiver is configured to receive data and transmit data.
