摘要： A method, network node and wireless device for receiving and/or mapping a physical downlink control channel, PDCCH, to resource elements of a time-frequency grid are provided in which the PDCCH is mapped to resource elements of the time-frequency grid by configuring resource element groups, REGs, each REG spanning one orthogonal frequency division multiplex, OFDM, symbol, and the PDCCH being at least two OFDM symbols. In accordance with one embodiment, the method includes receiving the PDCCH from the network node on one of a plurality of sets of physical resource blocks, PRBs.
