Abstract
Official abstract text for this publication.
A method and apparatus for transmitting an indication for device-to-device (D2D) mobility or D2D connection failure in a wireless communication system is provided. A first mobile device identifies a cell for mobility of the first mobile device or a second mobile device which has a connection with the first mobile device, and indicates the connection with the second mobile device to the cell. Also, the first mobile device detects failure of the connection with the second mobile device, and indicates the failure of the connection with the second mobile device to either the second mobile device or the cell.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for transmitting, by a first mobile device, an indication in a wireless communication system, the method comprising: identifying a cell for mobility of the first mobile device or a second mobile device which has a connection with the first mobile device; and indicating the connection with the second mobile device to the cell, wherein the connection with the second mobile device is indicated by an establishment cause included in a radio resource control (RRC) connection request message or an RRC connection setup complete message. 2. The method of claim 1 , wherein the cell for mobility is identified by a handover command. 3. The method of claim 2 , wherein the handover command is received from a target eNodeB (eNB), which controls the cell, via a serving eNB and the second mobile device. 4. The method of claim 1 , wherein the RRC connection request message or the RRC connection setup complete message includes an identity of the first mobile device. 5. The method of claim 1 , further comprising: receiving a D2D measurement configuration from the second mobile device; and transmitting a D2D measurement report to the second mobile device. 6. The method of claim 1 , further comprising: transmitting a D2D connection release request message, including information on the cell for mobility and the connection with the second mobile device, to the second mobile device. 7. The method of claim 1 , further comprising: receiving a D2D connection release message, including redirection information indicating redirected carrier frequency or redirected cell, from the second mobile device. 8. A method for transmitting, by a first mobile device, an indication in a wireless communication system, the method comprising: detecting failure of a connection with a second mobile device; and indicating the failure of the connection with the second mobile device to either the second mobile device or a cell, wherein the failure of the connection with the second mobile device is indicated by an establishment cause included in a radio resource control (RRC) connection request message or an RRC connection reestablishment request message. 9. The method of claim 8 , wherein the RRC connection request message or the RRC connection reestablishment request message includes an identity of the first mobile device. 10. The method of claim 8 , further comprising: transmitting an RRC connection setup complete message or an RRC connection reestablishment complete message. 11. The method of claim 10 , wherein the RRC connection setup complete message or the RRC connection reestablishment complete message includes an identity of the second mobile device and an identity of a cell of the first mobile device.
