Claim:
1. A method for monitoring a Physical Downlink Control CHannel (PDCCH) in a wireless communication system for receiving broadcast, multicast or unicast information, comprising: accessing, by one or more computer processors, a constraint for a Physical Downlink Control CHannel (PDCCH) that limits mapping of decoding candidates distributed on a plurality of carriers, each of which corresponds to one or more control channel elements (CCEs), wherein each of the one or more CCEs corresponds to a set of resource elements (REs), wherein the constraint includes one or more characteristics for limiting a number of blind decoding that has to be performed to successfully receive PDCCH sent via one or more carriers, wherein at least two carriers of the plurality of carriers are distributed with decoding candidates with different characteristics to avoid the decoding candidates with different characteristics distributed on the one or more CCEs of the at least two carriers of the plurality of carriers from overlapping each other, wherein the different characteristics include one or more of: different search spaces, or different subsets of aggregation levels; monitoring, by the one or more computer processors, a reduced set of decoding candidates on the at least two carriers of the plurality of carriers in accordance with the constraint; and blind decoding, by the one or more computer processors, the reduced set of decoding candidates.
