Abstract
A method and apparatus for performing a cell selection or a cell reselection in a wireless communication system is provided. A user equipment (UE) receives information on whether a cell supports a relay functionality or not, and performs a cell selection or a cell reselection according to the information. If the information indicates that the cell does not support the relay functionality, the cell can be considered as barred for relay functionality.
Claims11
A method for performing, by a user equipment (UE), a cell selection or a cell reselection in a wireless communication system, the method comprising:
- receiving information that indicates whether a relay functionality is supported by a cell,
- wherein the relay functionality is restricted to use only for proximity-based services (ProSe);
- and
- performing a cell selection or a cell reselection according to the received information,
- wherein, when the UE is configured to perform the relay functionality while camping on a current frequency, the UE considers the current frequency to be a highest priority when the relay functionality is performed,
- wherein the relay functionality contains two types of relay services including a first relay service for 1:M data transmitted by a remote UE and a second relay service for 1:1 data transmitted by the remote UE, and
- wherein the relay functionality is performed while the UE is in a Radio Resource Control (RRC) idle mode.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a memory;
- a transceiver;
- and
- a processor coupled to the memory and the transceiver,
- wherein the processor is configured to:
- control the transceiver to receive information that indicates whether a relay functionality is supported by a cell,
- wherein the relay functionality is restricted to use only for proximity-based services (ProSe);
- and
- perform a cell selection or a cell reselection according to the received information,
- wherein, when the UE is configured to perform the relay functionality while camping on a current frequency, the UE considers the current frequency to be a highest priority when the relay functionality is performed,
- wherein the relay functionality contains two types of relay services including a first relay service for 1:M data transmitted by a remote UE and a second relay service for 1:1 data transmitted by the remote UE, and
- wherein the relay functionality is performed while the UE is in a Radio Resource Control (RRC) idle mode.
