1. A method comprising:
determining at a network device a search space configuration associated with control resources on a plurality of sub-bands which are unlicensed, the search space configuration indicating candidates for detection of downlink control information for the plurality of sub-bands;
determining at the network device, from the search space configuration, positions of the candidates on the control resources within each of the plurality of sub-bands;
mapping at the network device an available number of candidates to the determined positions based on a transmission bandwidth assumed by a terminal device; and
transmitting from the network device downlink control information to the terminal device on the mapped candidates.
