Problems solved by technology

Additionally, the absence of control information may hamper data transmission on these carriers
In other words, a multi-carrier system cannot tell which received-controlled carrier is applicable
Furthermore, in a multi-carrier system or environment, uplink (UL) and downlink (DL) control allocation can be costly in overhead and user equipment (UE) allocation monitoring per carrier

Abstract

Systems and methodologies are described that facilitate assigning resources for an anchor carrier and an additional carrier with a grant message. The grant message communicated with an anchor carrier can include resource information a plurality of carriers. Moreover, the systems and methodologies that facilitate identifying control information for an anchor carrier and / or an additional carrier based upon an operating mode, wherein the operating mode is a legacy mode or an extended mode. Based on the operating mode, particular resources associated with control regions are monitored for control information for respective anchor carrier(s) or additional carrier(s).
