Zusammenfassung:	A method, network node and wireless device for mapping a short physical downlink control channel, sPDCCH, to resource elements of a time-frequency grid to achieve one of high frequency diversity and condensed frequency allocation are provided. According to one aspect, a method includes determining available time-frequency resources to be configured as short resource element groups, sREGs, configuring sREGs within a physical resource block, PRB, to map the sPDDCH to the resource elements. The number of sREGs depend upon a number of orthogonal frequency division multiplex, OFDM, symbols of the sPDCCH. Each sREG spans one OFDM symbol.
