Claim 15:
16. An access node, 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 access node at least to perform:
operate in a full duplex, FDX, mode when receiving and/or transmitting signals over a first set of communication lines and operate in a Time Division Duplex, TDD, mode when receiving or transmitting signals from a second set of communication lines, wherein symbols transmitted on a first communication line of the first set of communication lines have a first structure and symbols transmitted on a second communication line of the second set of communication lines have a second structure, and symbols with the first structure and symbols with the second structure have same symbol duration Tsymb; and
receive an upstream symbol with the second structure over a communication line of said second set at same time of transmitting a downstream symbol with the first structure over a communication line of the first set 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.
