Device to device user equipment and base station

A device to device (D2D) user equipment, comprising:

• a transceiver, being configured to receive a wireless signal, wherein the wireless signal has a hybrid access channel carrying a D2D hybrid access map, and the D2D hybrid access map is generated by a base station;
• and
• a processor electrically connected to the transceiver, being configured to retrieve the D2D hybrid access map from the hybrid access channel;
• wherein the D2D hybrid access map indicates a D2D resource block, a first D2D user equipment transmits a D2D hybrid access request to a second D2D user equipment via the D2D resource block, the second D2D user equipment transmits a D2D hybrid access response to the first D2D user equipment via the D2D resource block after receiving the D2D hybrid access request, and then the first D2D user equipment and the second D2D user equipment perform a D2D data transmission according to a piece of D2D data transmission information carried in the D2D hybrid access response.
