摘要

Methods and apparatus for using an unlicensed radio frequency band component carrier for uplink transmission are disclosed. A wireless communication device receives a carrier aggregation configuration, which can include at least one licensed radio frequency band component carrier and at least one unlicensed radio frequency band component carrier. The wireless communication device establishes a set of radio bearers and associates an unlicensed radio frequency band permission level with each of the radio bearers. The wireless communication device multiplexes uplink traffic for the radio bearers on the at least one licensed radio frequency band component carrier and the at least one unlicensed radio frequency band component carrier based at least in part on the unlicensed radio frequency band permission levels associated with the radio bearers.
