US 2014/0153478 A1 · CREATION AND SIGNALLING OF UE LISTS TO SUPPORT FREQUENCY SELECTIVE REPEATER OPERATION

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.

Dependent claims

A method of supporting frequency-selective repeaters in a wireless telecommunication system having a base station that serves a plurality of User Equipments (UEs) and one or more frequency-selective repeaters that amplify and forward signals between the base station and a portion of the UEs, said method comprising the steps of:

identifying by the base station, UEs for either a black list that identifies UEs for which signals are not to be amplified by a given repeater or a white list that identifies UEs for which signals are allowed to be amplified by the repeater;
sending the black list or white list from the base station to the repeater;
detecting by the repeater, an identity of a UE within the repeater's transmission range;
determining whether the detected UE is on the black list or white list;
when the UE is on the black list, determining by the repeater that signals scheduled for the UE are not to be amplified;
and
when the UE is on the white list, determining by the repeater whether to amplify signals scheduled for the UE.

4 more elements

A base station for supporting frequency-selective repeaters in a wireless telecommunication system, wherein the base station serves a plurality of User Equipments (UEs) and one or more frequency-selective repeater amplifies and forwards signals between the base station and a portion of the UEs, said base station comprising:

a UE classifier for identifying UEs that either require or do not require amplification by the repeater;
and
an interface unit for notifying the repeater of the identified UEs.
