ALLOCATION OF USER EQUIPMENT TEMPORARY IDENTIFIER BY RELAY NODE CONTROLLED BY BASE STATION Russian patent published in 2012 - IPC H04W76/02 

FIELD: information technology.

SUBSTANCE: communication system comprises a base station and a relay node connected to the base station. The base station maintains a set of identifiers, where each identifier of the set can at least be temporarily allocated to user equipment for identifying the user equipment when it resides in a cell of the base station. From the set of identifiers of the base station at least one subset of identifiers is extracted, and assigned to the relay node. The relay node can respond to a connection setup request from user equipment by providing it with an identifier from the subset of identifiers assigned to it. The relay node also transmits to the base station information on the connection setup request and on the identifier provided to the user equipment.

EFFECT: widening coverage area of a cell using relay nodes, and reduced delays associated with use of a relay, by providing the user equipment with an identifier assigned for the corresponding relay node.
