Abstract:
The invention discloses a method (600) for use in a wireless communications system (100) in which there is at least one node (110-115) which controls the traffic to and from all user terminals (130) in a cell (120) within the system. In the system (100), use is made of the TDD principle for communication between said controlling node (110-115) and its user terminals (130), and according to the method (600), the controlling node transmits (610) a beacon signal for use as a signal quality indicator by the user terminals, said beacon signal being transmitted in a first TDD time slot (232). The user terminals (130) measure (620) the signal quality of the beacon signal and the signal quality in at least a second TDD time slot (234), and report (630) measurements of the signal qualities in both said first and second time slots to the controlling node.
