Abstract
A wireless transmit/receive unit (WTRU) may receive from a network resource allocation information for device to device (D2D) communication. The WTRU may select, from the received resource allocation information for a transmission time interval (TTI), resources for a D2D channel. The WTRU may transmit, with use of the selected resources, data directly to another WTRU.
Claims12
A wireless transmit/receive unit (WTRU) comprising:
- a processor;
- and
- a transceiver operatively coupled to the processor;
- the processor and the transceiver configured to send, to a network, a registration message indicating whether the WTRU is capable of device-to-device (D2D) communication;
- on a condition the WTRU is capable of D2D communication, the processor and the transceiver configured to send, to the network, a request for assistance in discovering at least one other WTRU in proximity to the WTRU;
- the processor and the transceiver configured to receive, from the network, in response to the request for assistance in discovering the at least one other WTRU in proximity to the WTRU, assistance information including one or more of a unique identifier or filtering information;
- the processor and the transceiver configured to, using the assistance information, perform a device discovery procedure to discover the at least one other WTRU in proximity to the WTRU;
- the processor and the transceiver configured to provide, to the network, an indication of a result of the device discovery procedure;
- the processor and the transceiver configured to establish a link for D2D communication with the at least one other WTRU;
- and
- the processor and the transceiver configured to transmit, using the established link, application data directly to the at least one other WTRU based on a Quality of Service (QoS) requirement associated with the application and a QoS supported by the established link.
A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
- send, to a network, a registration message indicating whether the WTRU is capable of device-to-device (D2D) communication;
- on a condition the WTRU is capable of D2D communication, sending, to the network, a request for assistance in discovering at least one other WTRU in proximity to the WTRU;
- receiving, from the network, in response to the request for assistance in discovering the at least one other WTRU, assistance information including one or more of a unique identifier or filtering information;
- performing, using the assistance information, a device discovery procedure to discover the at least one other WTRU in proximity to the WTRU;
- establishing a link for D2D communication with the at least one other WTRU;
- and
- transmitting, using the established link, application data directly to the at least one other WTRU based on a Quality of Service (QoS) requirement associated with the application and a QoS supported by the established link.
