A configuration of a first search space for monitoring control channel candidates over a first set of symbols can be received. A configuration of an alternative set of search spaces containing at least a second search space for monitoring control channel candidates over a second set of symbols can be received. A DCI scheduling an uplink transmission over a third set of symbols can be received. A determination can be made as to whether the uplink transmission overlaps with the first set of symbols. Control channel candidates in the first search space can be monitored when the uplink transmission does not overlap with the first set of symbols. Control channel candidates can be monitored in the second search space instead of the first search space when the uplink transmission overlaps with the first set of symbols.
