Abstract

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.

Description

technical field [0001] Embodiments described herein relate generally to wireless communication technologies. More specifically, embodiments of the present invention relate to uplink transmissions on component carriers in a license-exempt radio frequency band using a wireless communication device capable of carrier aggregation. Background technique [0002] Modern wireless communication devices continue to evolve, offer increasing capabilities, and are now in fact used by consumers to access a variety of data-intensive services via wireless networks. For example, wireless communication devices are used to access a variety of Internet services, such as audio / video streaming services, web browsing. The exponential growth in demand on wireless networks to support such data-intensive services has replaced the need for wireless network operators to upgrade their wireless networks to support both increased data capacity and faster data rates. Accordingly, there are ongoing effort...
