Communication data sending method and device, and user equipment

A communication data sending device, located in User Equipment UE, comprising a processor and a storage device, wherein the storage device stores processor-executable programs, and the programs comprise:

• an indication module configured to indicate a Device to Device (D2D) data channel resource through D2D data channel resource indication information in D2D control indication information;
• bear the D2D control indication information on one of the following resources for sending:
• D2D control channel resource, D2D data channel resource and D2D scheduling indication resource;
• and
• a sending module configured to send D2D communication data on the D2D data channel resource,
• wherein the indication module is configured to
• indicate a time domain resource and a frequency domain resource of D2D data channel through the D2D data channel resource indication information;
• wherein the indication module is further configured to generate the D2D control indication information, wherein the D2D data channel resource indication information is contained in the D2D control indication information and indicates the time domain resource and the frequency domain resource of the D2D data channel through indication information of N bits,
• wherein the indication module is further configured to:
• indicate the time domain resource of the D2D data channel through indication information of N1 bits, and indicate the frequency domain resource of the D2D data channel through indication information of N2 bits, wherein N1+N2=N,
• wherein under a situation that the D2D data channel resource indication information indicates the time domain resource of the D2D data channel through indication information of N1 bits, the indication module is further configured to:
• indicate the time domain resource of the D2D data channel through the indication information of N1 bits by a way of a timing pattern, wherein the time domain resource of the D2D data channel refers to one or more D2D data subframes contained by the D2D data channel in a time domain and used for sending the D2D communication data.
