Claim 12:
13. A communication controller for 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;
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
the communication controller comprising at least one processor, and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the communication controller at least to:
control that an upstream symbol with the second structure is received by the access node from the second communication line at the 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.
