Abstract  Abstract

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.
