Abstract
A system and method of data communication is provided for use in a wireless communication system. The wireless communication system includes a base station, a relay user equipment (UE) and an out of coverage UE (OOC-UE). The method includes receiving, at the relay UE and from the base station, a relay cycle configuration, the relay cycle configuration defining a relay cycle including a first time period for device to device (D2D) communication, and a second time period for cellular communication. The method then includes receiving, at the relay UE by D2D communication, within the first time period and from the out of coverage UE (OOC-UE), relay data, and providing, from the relay UE by cellular communication, within the second time period and to the BS, the relay data.
Claims21
A data communication method for use in a wireless communication system, the wireless communication system including a base station (BS), a relay user equipment (UE) and an out of coverage UE (OOC-UE), the method including:
- receiving, at the relay UE and from the BS, first information, second information and third information, the first information indicating a first time period including a second time period reserved for device to device (D2D) communication and a third time period reserved for cellular communication, the second information indicating the third time period, and the third information including a relay offset indicator defining an offset from a start of a system frame number 0 to a start of the first time period;
- receiving, at the relay UE by D2D communication, within the second time period and from the OOC-UE, relay data;
- and
- providing, from the relay UE by cellular communication, within the third time period and to the BS, the relay data.
A wireless communication system including:
- a base station (BS);
- an out of coverage UE (OOC-UE);
- and
- a relay user equipment (UE), the relay UE configured to:
- receive, from the base station, first information, second information and third information, the first information indicating a first time period including a second time period reserved for device to device (D2D) communication and a third time period reserved for cellular communication, the second information indicating the third time period, the third information including a relay offset indicator defining an offset from a start of a system frame number 0 to a start of the first time period;
- receive, by D2D communication, within the second time period and from the OOC-UE, relay data;
- and
- provide, by cellular communication, within the third time period and to the BS, the relay data.
