FIELD: electrical communication engineering.
SUBSTANCE: invention relates to communication systems. Result is achieved by the fact that the wireless device (UE1, UE2, UE3) monitors the search space by receiving (510) orthogonal frequency division multiplexing (OFDM) symbols in the downlink time slot. OFDM symbol is included in set (210, 220, 230) of control resources (basic set) from resource elements adapted to transfer control information. Basic set (210, 220, 230) is associated with at least one property. Wireless device (UE1, UE2, UE3) identifies (520) at least one first property (P) from at least one property of base set (210, 220, 230). Wireless device (UE1, UE2, UE3) then monitors at least one specific search space for a control message associated with the wireless device (UE1, UE2, UE3) based on the identified at least one first property (P) of base set (210, 220, 230).
EFFECT: technical result is monitoring search spaces with high efficiency.
