Abstract
Systems and methods are disclosed for establishing a device-to-device (D2D) group amongst a plurality of user equipments (UEs). In one embodiment a target UE transmits, using D2D communication, a request message inviting at least one other UE to be part of a D2D group with the target UE. A neighbor UE receives the request message and transmits a report message indicating that the neighbor UE will be part of the D2D group with the target UE. A base station receives the report message and transmits to the target UE and to the neighbor UE a confirmation message indicating that the neighbor UE is in the D2D group with the target UE.
Claims20
A method performed by a target user equipment (UE), the method comprising:
- receiving a preamble from a base station;
- transmitting, using device-to-device (D2D) communication, a request message to a neighbour UE, the request message including the preamble, and the request message inviting at least one other UE to be part of a D2D group with the target UE;
- and
- receiving a confirmation message from the base station, the confirmation message indicating that the neighbour UE is in the D2D group with the target UE.
A target user equipment (UE) comprising:
- at least one antenna;
- a device-to-device (D2D) communication module configured to instruct the target UE to:
- receive a preamble from a base station;
- transmit, using D2D communication, a request message to a neighbour UE, the request message including the preamble, and the request message inviting at least one other UE to be part of a D2D group with the target UE;
- and
- receive a confirmation message from the base station, the confirmation message indicating that the neighbour UE is in the D2D group with the target UE.
