1. A method comprising:generating, by a network element, at least one transmission gap within data transmission performed by the network element, wherein the at least one transmission gap is generated as a part of a listen-before-talk procedure for communication on an unlicensed band;
transmitting a control message to at least one terminal device, wherein the control message comprises a first request to perform, by the at least one terminal device, a first interference measurement during the at least one transmission gap, wherein the control message further comprises a second request to perform, by the at least one terminal device, a second interference measurement during the said data transmission;
receiving, from the at least one terminal device, an interference report associated with the listen-before-talk procedure comprising information that is at least partly based on the first and the second interference measurements; and
based on the received interference report indicating that the unlicensed band is not occupied, providing communication resources for the communication.
