1. A method of coordinating communications in a communication system, the communication system comprising an access node, communicatively coupled to
a first set of remote communication units being configured to operate in a full duplex, FDX, mode via respective ones of a first set of communication lines; and
a second set of remote communication units being configured to operate in a Time Division Duplex, TDD, mode via respective ones of a second set of communication lines;
wherein symbols transmitted on a first communication line connecting a first remote communication unit belonging to the first set of remote communication units to the access node have a first structure and symbols transmitted on a second communication line connecting a second remote communication unit belonging to the second set of remote communication units to the access node have a second structure and the symbol with the first structure and the symbol with the second structure having same symbol duration Tsymb; and
wherein said method of coordination comprises:
controlling that an upstream symbol with the second structure is received by the access node from the second communication line at a same time as a downstream symbol with the first structure is transmitted by the access node onto the first communication line such that a start of the upstream symbol with the second structure is aligned in time with respect to a start of the downstream symbol with the first structure.
