1. A method in a receiver circuitry, which is adapted to receive from a wireless network system demodulation reference signals, DMRS, and encoded control channel messages mapped to a plurality of physical resource blocks, PRBs, the receiver circuitry being configured to evaluate a plurality of control channel message candidates, each control channel message candidate being associated with one DMRS candidate of a set of DMRS candidates, a DMRS candidate comprising a plurality of PRB indicators and one DMRS sequence identifier, wherein the method comprises:
receiving a signal from the wireless network system; calculating a DMRS sequence based on the DMRS sequence identifier of a first DMRS candidate; extracting a signal sequence from the received signal using the plurality of PRB indicators of the first DMRS candidate; computing one first quality measure for the first DMRS candidate based on the extracted signal sequence and the calculated DMRS sequence; controlling a decoding of the plurality of control channel message candidates by selecting based on said first quality measure at least one control channel message candidate for decoding of a received control channel message. |
