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。

摘要： The present disclosure relates to a method for allocating Time Transmission Intervals, TTI, during Up Link, UL, transmissions in a shared radio cell environment. The present disclosure also relates to a network node for performing said allocation method. The allocation is performed by determining for each network node (10; 20A; 20B; 20C) in the shared radio cell environment which UEs (30) it serves and listens to. The TTIs are the allocated such that the UE transmission for UEs related to a network node (10; 20A; 20B; 20C) is coordinated by scheduling said UE transmission in the same TTI frame for a serving network node (10; 20A; 20B; 20C) and for one or more of listening network nodes (10; 20A; 20B; 20C) in the shared radio cell environment.
