Abstract
A user equipment UE reports its UE-specific channel quality to the network. The network uses this to narrow a search space in which the UE looks for its downlink control signaling. In one embodiment the search space is defined by downlink signaling the network sends. The width of the search space may also select between types of downlink control signaling (for example, between PDCCH and E-PDCCH). In the specific examples described the poorest channel qualities result in the whole-bandwidth PDCCH being used while better channel qualities result in progressively narrower search spaces to look for an E-PDCCH.
