摘要： A wireless terminal comprises a communications interface and a congestion controller. The communications interface communicates over a radio interface with a base station. The congestion controller, upon occurrence of a congestion indication, reduces uplink transmission power of the wireless terminal by lowering a transport format combination for use by the wireless terminal for transmitting an enhanced dedicated uplink channel (E-DCH) over the radio interface to the 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.

摘要： In a cellular radio system Transmission Power Control (TPC) power offset is set so that it is adjusted for each transmitting radio base station based on available relevant measurements that reflect the quality of the downlink channel carrying the uplink TPC command whereby an improved performance is obtained. The TPC power offset can for example be based on an estimated uplink Dedicated Physical Control CHannel (DPCCH) SINR, the number of TPC “up” and the number of TPC “down” sent by a radio base station and aggregated UE receiver power or UE transmit power over a number N slots. Also a mobile station used in a cellular radio system supporting soft handover may be adapted to apply TPC discarding thresholds based on the number and the quality of simultaneously received TPC commands. The discarding procedure in the mobile station may also be carried out selectively such that TPC commands that are determined to be unreliable are not discarded but selectively discarded based on how reliable they are determined to be.

摘要： 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.
摘要翻译：一种在无线电信系统中支持频率选择中继器（eNode-RR）的方法。基站（eNodeB）将用户设备（UE）分为两类或用户列表：包含可能需要中继器协助的UE的白名单，以及包含不需要中继器协助的UE的黑名单。 eNodeB将这两个列表中的一个发送到eNodeR。 eNodeR不放大为黑名单UE调度的资源块（RB）。每个中继器可以自己决定是否通过测量来自UE的信号并将其与预定标准进行比较来放大非黑名单UE的信号。
