Claim Text:
1. A method for transmitting downlink control information in a Long-Term Evolution (LTE) radio communication system, the method comprising, for a first subframe in which a plurality of non-overlapping subsets of resource elements in at least one block of time-frequency resources are to be aggregated for transmitting the downlink control information: determining members of a first set of aggregation levels usable to aggregate the non-overlapping subsets of resource elements for transmitting first downlink control information, wherein said determining is based on a number of reference signal symbols to be transmitted in the at least one block of time-frequency resources in the first subframe; mapping the first downlink control information to one or more first non-overlapping subsets of resource elements in the at least one block of time-frequency resources, according to an aggregation level selected from the determined first set; and transmitting the first downlink control information in the one or more first non-overlapping subsets.
