Abstract
Some embodiments provide a method for transmitting a downlink control channel in at least one block of resources. The downlink control channel comprises a set of resource element groups. The method may be executed by a transmitting node, e.g., an eNB. The transmitting node first determines whether to transmit the downlink control channel using localized or distributed transmission. Responsive to determining to use localized transmission, the transmitting node performs the transmission such that all resource element groups in the set that are comprised in the same block of resources are mapped to the same antenna port, and the antenna port depends on which subset of resource element groups in the block of resources are used for the downlink control channel.
