TECHNIQUES FOR ALLOCATION OF CONTROL CHANNELS

摘要

Techniques are described for setting the Physical Downlink Control Channel search spaces for component carriers. If any component carrier is de-activated, the Carrier Indicator Fields (CIF) of remaining activated component carriers can be set to consecutive values. The User Element can utilize its identifier to determine the starting point Control Channel Elements in each subframe. The locations of Control Channel Elements for a component carrier can be determined based on its CIF. Accordingly, search spaces for different component carriers can potentially be closely spaced but not overlap.
