Interfering in time-division duplex communication

A non-transitory computer readable storage medium having computer readable program instructions thereon for causing a processor to carry out the steps of:

• receiving, using a receiver, wireless transmissions, from a second node;
• wherein the second node communicates with a first node by time-division duplex communication, wherein the first node transmitting during time slots allocated to said first node and the second node transmitting during separate time slots allocated to said second node, said first node transmitting at a respective one of a plurality of frequency bands during each of said time slots allocated to said first node;
• determining a time slot allocated to said first node, out of the time slots allocated to said first node, the determining is based on said received transmissions;
• subdividing said determined time slot into consecutive time intervals;
• and
• instructing an apparatus interfering with said time-division duplex communication to transmit respective interference signals during a plurality of said time intervals, each of said interference signals being for transmission on a respective one of said plurality of frequency bands, wherein for at least two of said time intervals said interference signals are transmitted on different frequency bands.
