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.

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.

A multi radio access technology layer (MRL) is a convergence layer solution, located between the protocol layers and the technology-dependent MAC layers. The MRL layer is technology independent and uses the information received from the underlying technologies to select the most appropriate uplink and downlink technologies to match the respective service requirements.

Data traffic may be mapped such that it may be routed via a component carrier. The data traffic may be mapped based on QoS, traffic offload, or the like. This may provide the ability to map certain data to specific component carriers. For example, this may provide a user subscription model with the ability to map one or more services to license exempt (LE) carriers, but not to other carriers. As another example, a user downloading a high definition movie may not want this to be counted towards his or her monthly quota on a licensed carriers or may want to pay flat rate to access supplementary carriers for such services. Allowing data to be mapped such that it may be routed via a component carrier via a component carrier may allow the user to map the data for the high definition movie to a LE carrier.

A radio interface layer media independent handover (RIL MIH) client functionality enables transparent inter-system handover of a wireless transmit/receive unit (WTRU) between different radio access technologies (RATs), without user intervention. The RIL MIH client interacts with RIL drivers and proxies, informs the RIL proxies of the handover status, then the proxies interact with a new driver in use. A WTRU is modified to add MIH functionality to a telephony server to support inter-system handover.

A device may include a trusted component. The trusted component may be verified by a trusted third party and may have a certificate of verification stored therein based on the verification by the trusted third party. The trusted component may include a root of trust that may provide secure code and data storage and secure application execution. The root of trust may also be configured to verify an integrity of the trusted component via a secure boot and to prevent access to the certain information in the device if the integrity of the trusted component may not be verified.
