摘要： A method and apparatus for controlling crosslink, XL, establishment are disclosed. In the method and apparatus, the XL (203) between a terminal wireless transmit/receive unit, T-WTRU, (201) and a helper WTRU, H-WTRU, (202) is controlled, whereby the T-WTRU (201) and the H-WTRU (202) may be in a radio resource control, RRC, Idle mode and may perform discontinuous reception, DRX. Further, the T-WTRU (201) may transition between infrastructure coverage mode and WTRU-to-WTRU, W2W coverage mode. Additionally, neighbor discovery and H-WTRU selection are performed and association between the T-WTRU (201) and H-WTRU (202) is established and maintained.

摘要： A grant that includes a resource allocation for a subframe set may be communicated. The subframe set may include a subframe resource and another subframe resource following the subframe resource. Sensing, during a sensing time prior to utilization of the subframe resource, that the unlicensed spectrum is available may be performed. Transmitting, based on the sensing, data on the subframe resource and the another subframe resource without further sensing may also be performed.

摘要： Described herein are methods to enable wireless cellular operation in unlicensed and lightly licensed, (collectively referred to as license exempt spectrum. Cognitive methods are used to enable use of unlicensed bands and/or secondary use of lightly licensed bands. Wireless devices may use licensed exempt spectrum as new bands in addition to the existing bands to transmit to a wireless transmit/receive unit (WTRU) in the downlink direction, or to a base station in the uplink direction. The wireless devices may access license exempt spectrum for bandwidth aggregation or relaying using a carrier aggregation framework. In particular, a primary component carrier operating in a licensed spectrum is used for control and connection establishment and a second component carrier operating in a licensed exempt spectrum is used for bandwidth extension.

摘要： A wireless transmit/receive unit (WTRU) may receive discovery related configuration information that includes discovery filtering information and information for a non-long term evolution radio access technology (non-LTE RAT). The WTRU may monitor a device to device (D2D) communication interface on the non-LTE RAT based on the discovery filtering information and send a report that includes information associated with the discovery filtering information. The WTRU may receive a message to allow the WTRU to establish a D2D communication link with another WTRU using the non-LTE RAT.
