Abstract
A method in a relay node operating in a time division duplex system wherein the relay node transmits downlink pilot timeslot information to a user terminal in a first temporal region of a special sub-frame, communicates with a base station during a second temporal region of the special sub-frame, and configures a third temporal region of the special sub-frame, wherein the second temporal region is configured as a guard period for communications between the relay node and the user terminal.
