1. A first wireless transmit/receive unit (WTRU) comprising:
a processor configured to at least:
receive, from a network, a first configuration information associated with scheduling of device-to-device transmissions, wherein the first configuration information indicates device-to-device regions associated with the device-to-device transmissions and resources associated with the device-to-device transmissions, wherein each device-to-device region of the indicated device-to-device regions comprises a respective plurality of contiguous physical resource blocks (PRBs), and wherein each resource of the indicated resources comprises a respective plurality of symbols;
receive, from the network, a second configuration information, wherein the second configuration information indicates a radio network temporary identifier (RNTI) associated with scheduling of the device-to-device transmissions;
receive, from the network, a physical downlink control channel (PDCCH) transmission, wherein a portion of the PDCCH transmission is scrambled by the RNTI;
determine a downlink control information (DCI) from the PDCCH transmission using the RNTI, wherein the DCI includes scheduling information, and wherein the scheduling information indicates at least one resource, of the resources, to be used to send a device-to-device transmission; and
send the device-to-device transmission to a second WTRU using the indicated at least one resource and at least one device-to-device region of the indicated device-to-device regions.
