Time-frequency resources in a single PRB pair are used for both frequency-localized transmissions as well as distributed transmissions. A first control message is transmitted (2710) to a first user equipment (UE) using a first PRB pair, using first subsets of resource elements that are aggregated in a frequency-localized manner and that are transmitted using a single antenna port. A second control message to a second UE is simultaneously transmitted (2710), also using the first PRB pair, using second subsets of resources that are aggregated in a frequency-distributed manner across the first PRB pair and one or more additional PRB pairs and that are transmitted using at least two antenna ports, including the single antenna port used to transmit the symbols in the first non-overlapping subsets of resource elements.
