Systems and methods for control plane for d2d communications

A method for managing a D2D communication at an eNB, the method comprising:

• receiving information about a D2D UE group communication, wherein the information comprises a D2D group ID for a D2D communication link of a D2D group, an identity of a D2D group master, and information related to at least one of a plurality of eNBs managing the D2D communication link;
• determining that the eNB is the D2D group master;
• and
• communicating a resource allocation to at least one of a plurality of eNBs for at least one D2D UE in the D2D group.

A wireless device performing device-to-device (D2D) communication, comprising:

• a memory storage comprising instructions;
• and
• one or more processors in communication with the memory storage, wherein the one or more processors execute the instructions to:
• transmit D2D configuration information to a user equipment (UE);
• receive a D2D buffer status report (BSR) for a D2D link, wherein the D2D BSR comprises an amount of D2D data available for transmission at the UE and comprises a first logical channel identifier (LCID) for the D2D BSR;
• allocate resources for the D2D link;
• and
• transmit a resource allocation to the UE.

An apparatus comprising:

• a memory storage comprising instructions;
• and
• one or more processors in communication with the memory storage, wherein the one or more processors execute the instructions to:
• receive information about a D2D UE group communication, wherein the information comprises a D2D group ID for a D2D communication link of a D2D group, an identity of a D2D group master, and information related to at least one of a plurality of eNBs managing the D2D communication link;
• determine that the apparatus is the D2D group master;
• and
• communicate a resource allocation to at least one of a plurality of eNBs for at least one D2D UE in the D2D group.
