Abstract

Various aspects of the disclosure relate to allocating control signaling resources for multiple carrier scenarios. In an example implementation, N-to-1 mapping is used between forward link control signaling resource allocation indices (e.g., control channel elements) and return link control signaling resources (e.g., for ACK/NACK signaling) indices in each return link component carrier. A collision between forward link control signaling assignments for different user terminals (UTs) may occur when UT-specific search spaces overlap each other. Such a collision may be avoided, for example, by scheduling different UTs on different return link component carriers, scheduling return link grants instead of forward link grants, or scheduling a different forward link control signaling candidate that is associated with a different forward link control signaling resource allocation index.
