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 transceiver;
- and
- a processor operatively coupled to the transceiver;
- wherein the transceiver and the processor are configured to receive, from a network in a radio resource control (RRC) message, resource allocation information for device-to-device (D2D) communication among a plurality of WTRUs, wherein the resource allocation information for D2D communication incudes frequency information, and wherein the resource allocation information for D2D communication is different from resource allocation information for WTRU-to-network communication;
- the processor is further configured to select, from the received resource allocation information for D2D communication, a subset of resources for a D2D channel;
- the processor is further configured to establish a bearer for D2D transmission, wherein the bearer for D2D transmission has a Quality of Service (QoS) requirement derived from a QoS requirement of an Evolved Packet System (EPS) bearer;
- and
- the transceiver is configured to transmit, using the selected subset of resources, data directly to another WTRU based on the QoS requirement of the bearer for D2D transmission.
A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
- receiving, from a network in a radio resource control (RRC) message, resource allocation information for device-to-device (D2D communication among a plurality of WTRUs, wherein the resource allocation information for D2D communication includes frequency information, and wherein the resource allocation information for D2D communication is different from resource allocation information for WTRU-to-network communication;
- selecting, from the received resource allocation information for D2D communication, a subset of resources for a D2D channel;
- establishing a bearer for D2D transmission, wherein the bearer for D2D transmission has a Quality of Service (QoS) requirement derived from a QoS requirement of an Evolved Packet System (EPS) bearer;
- and
- transmitting, using the selected subset of resources, data directly to another WTRU based on the QoS reqirement of the bearer for D2D transmission.
