FIELD: radio engineering, communication.
SUBSTANCE: invention relates to wireless communication engineering and can be used in a multicarrier communication system. A wireless communication method comprises user equipment (UE) monitoring downlink channel information (DCI) from a first carrier on a first DCI format. The UE receives a reconfiguration message indicating transition between downlink control signalling without signalling between carriers and with signalling between carriers, respectively. After receiving the reconfiguration message, a second DCI format is also monitored, wherein the monitoring includes monitoring a first set of received downlink elements based on the first DCI format, which corresponds to a common search space at a first carrier, and monitoring a second set based on the first and second DCI formats, wherein the second set corresponds to the search space, typical for the UE, at the first carrier.
EFFECT: supporting fault elimination operations in a multicarrier communication system.
