Claim 0:
1. A method in a wireless device for receiving information on a physical downlink control channel, PDCCH, signaled by a network node, the PDCCH being for a transmission time interval of 7 or less orthogonal frequency division multiplex, OFDM, symbols, the method comprising:
receiving the PDCCH from the network node, the PDCCH being mapped to resource element groups, REGs, each REG spanning only one orthogonal frequency division multiplex, OFDM, symbol, the PDCCH being of 2 or more OFDM symbols, the PDCCH comprising at least one control-channel element, CCE, a CCE to REG mapping being one of localized in a frequency domain and distributed in the frequency domain, and for the CCE to REG mapping distributed in the frequency domain, the REGs being distributed in groups of REGs, each group of REGs being mapped to consecutive physical resource blocks, PRBs, a REG consisting of 1 PRB within 1 OFDM symbol.
