ADJUSTING MULTI-CARRIER ALLOCATION IN WIRELESS NETWORKS

摘要

PROBLEM TO BE SOLVED: To facilitate adjusting allocation of carriers in wireless communications.SOLUTION: A mobile device establishes communication with a base station over a number of allocated carriers for simultaneous communication thereover. The mobile device experiences a decrease in power amplifier (PA) headroom causing dropping of at least one carrier and reports the dropping to the base station. The base station subsequently awaits a carrier request message from the mobile device before allocating additional carriers, or allocates an additional carrier on the basis of a determination that the mobile device can handle the new carrier. The mobile device transmits a carrier request message when the PA headroom returns to a threshold level.
