Patent ID: 8675592

Claim:
A wireless communication device, comprising: a receiver; a processor and at least one memory including program code which, when executed by the processor, causes the wireless communication device to: decode resource mapping information from a subframe signal received via the receiver to obtain information about arrangement of one or more control channels for subframe signals, each subframe signal comprising a plurality of physical resource blocks (PRBs) only a portion of which are occupied by the one or more control channels; determine, based on the obtained information about arrangement of the one or more control channels for subframe signals, information related to aggregation level (AL) of one or more of the control channels of a common subframe signal and information related to PRBs comprising one or more elements of the one or more of the control channels of the common subframe signal, the information related to PRBs comprising PRB cluster size wherein a PRB cluster comprises a plurality of PRBs and a number of PRBs in each PRB cluster is variable such that a first one of the PRB clusters has a different number of PRBs than a second one of the PRB clusters for each different bandwidth; decode one or more elements of a control channel from another subframe signal received via the receiver, based on the determined information related to the PRBs comprising that control channel and the determined information related to the AL of that same control channel, the decoding comprising determining interleaving depth (IDP) of the PRB cluster comprising the one or more elements of that control channel; form a control message from the one or more elements of that control channel; and provide the control message to a higher protocol layer.
