Abstract
Official abstract text for this publication.
A method and apparatus for selecting a device-to-device (D2D) group in a wireless communication system is provided. A user equipment (UE) detects at least two D2D groups, and if the UE has no capability for supporting the at least two D2D groups, the UE selects one D2D group among the at least two D2D groups based on at least one of measurement results from the at least two D2D groups or group priority of each of the at least two D2D groups.
First claim
Opening claim text (preview).
1 . A method for selecting, by a user equipment (UE), a device-to-device (D2D) group in a wireless communication system, the method comprising: detecting at least two D2D groups; and if the UE has no capability for supporting the at least two D2D groups, selecting one D2D group among the at least two D2D groups based on at least one of measurement results from the at least two D2D groups or group priority of each of the at least two D2D groups. 2 . The method of claim 1 , wherein the selected one D2D group has a higher priority than other D2D groups among the at least two D2D groups. 3 . The method of claim 1 , wherein the selected one D2D group has a better measure signal quality than other D2D groups among the at least two D2D groups. 4 . The method of claim 1 , further comprising: receiving identities (IDs) for the at least two D2D groups from a network. 5 . The method of claim 1 , further comprising: receiving the group priority of each of the at least two D2D groups from a network. 6 . The method of claim 1 , further comprising: receiving the group priority of each of the at least two D2D groups from the at least two D2D groups. 7 . The method of claim 6 , wherein the group priority of each of the at least two D2D groups is received via a group invitation message. 8 . The method of claim 1 , wherein the measurement results from the at least two D2D groups are based on reference signals received from the at least two D2D groups. 9 . The method of claim 1 , further comprising: transmitting a joining request to the selected one D2D group. 10 . The method of claim 9 , further comprising: leaving a D2D group where the UE joined previously. 11 . A user equipment (UE) in a wireless communication system, the UE comprising: a radio frequency (RF) unit for transmitting or receiving a radio signal; and a processor coupled to the RF unit, and configured to: detect at least two D2D groups; and if the UE has no capability for supporting the at least two D2D groups, select one D2D group among the at least two D2D groups based on at least one of measurement results from the at least two D2D groups or group priority of each of the at least two D2D groups. 12 . The UE of claim 11 , wherein the selected one D2D group has a higher priority than other D2D groups among the at least two D2D groups. 13 . The UE of claim 11 , wherein the selected one D2D group has a better measure signal quality than other D2D groups among the at least two D2D groups. 14 . The UE of claim 11 , wherein the processor is further configured to: receive identities (IDs) for the at least two D2D groups from a network. 15 . The UE of claim 11 , wherein the measurement results from the at least two D2D groups are based on reference signals received from the at least two D2D groups.
