Abstract: A method of supporting frequency-selective repeaters (eNodeRs) in a wireless telecommunication system. A base station (eNodeB) classifies User Equipments (UEs) into two categories or lists of users: a white list containing UEs that may need the assistance of repeaters, and a black list containing UEs that do not need repeater assistance. The eNodeB transmits one of these two lists to the eNodeRs. The eNodeRs do not amplify resource blocks (RBs) scheduled for black list UEs. Each repeater may decide on its own whether to amplify signals for a non-black list UE by measuring signals from the UE and comparing them with predefined criteria.

Abstract: A wireless terminal comprises a communications interface and a congestion controller. The communications interface communicates over a radio interface with a base station.

In an example embodiment and mode, the congestion controller performs an expedited transport format combination reduction procedure which is distinct from Dedicated Physical Control Channel (DPCCH) power reduction based on a command received in a closed loop power control procedure, e.g., on a Fractional-DPCH (F-DPCH) channel.
