Abstract

A method and apparatus for establishing a device-to-device (D2D) connection in a wireless communication system is provided. A first mobile device transmits a D2D related message including an identity of a second mobile device, which is connected with the first mobile device, to a network. Or, a first mobile device receives a D2D related message including an identity of a second mobile device, which is connected with the first mobile device, from a network.

Claims

1. A method performed by an eNodeB (eNB) in a wireless communication system, the method comprising:

receiving, by the eNB from a first user equipment (UE) via a media access control (MAC) protocol data unit (PDU), a first type of buffer status report (BSR) for a device-to-device (D2D) connection between the first UE and a second UE and a second type of BSR for a radio resource connection (RRC) connection between the first UE and the eNB,

wherein a header of the MAC PDU informs a type of BSR among the first type of BSR and the second type of BSR; and

transmitting, by the eNB to the first UE, a grant on a D2D resource for the D2D connection between the first UE and the second UE based on the first type of BSR,

wherein the first UE is configured with an evolved-UMTS terrestrial radio access network (E-UTRAN) planned mode in which the eNB is responsible for radio resources for the D2D connection.

2. The method of claim 1, wherein a MAC control element (CE) in the MAC PDU includes information on the second UE.

3. The method of claim 1, wherein the D2D resource is used by the first UE for transmitting data to the second UE.

4. An eNodeB (eNB) in a wireless communication system, the eNB comprising:

a memory;

a radio frequency (RF) unit; and

a processor, coupled to the memory and the RF unit, that;

controls the RF unit to receive, from a first user equipment (UE) via a media access control (MAC) protocol data unit (PDU), a first type of a buffer status report (BSR) for a device-to-device (D2D) connection between the first UE and a second UE and a second type of BSR for a radio resource connection (RRC) connection between the first UE and the eNB,

wherein a header of the MAC PDU informs a type of BSR among the first type of BSR and the second type of BSR, and

controls the RF unit to transmit, to the first UE, a grant on a D2D resource for the D2D connection between the first UE and the second UE based on the first type of BSR,

wherein the first UE is configured with an evolved-UMTS terrestrial radio access network (E-UTRAN) planned mode in which the eNB is responsible for radio resources for the D2D connection.

5. The eNB of claim 4, wherein a MAC control element (CE) in the MAC PDU includes information on the second UE.

6. The eNB of claim 4, wherein the D2D resource is used by the first UE for transmitting data to the second UE.
