Abstract
A method and network node for determining radio resources for allocation to a downlink control channel in a communication network are disclosed. According to one aspect, a method includes receiving, over a predetermined measurement period, a plurality of reports from a wireless device, each report being indicative of a channel quality within at least a subband of an available bandwidth of the communication network. The method further includes for each subband for which at least one report has been received, determining a variance of the channel quality and an average of the channel quality over the predetermined measurement period. The method further includes determining subbands having at least a variance of the channel quality less than a first threshold.
