Apparatuses, methods and computer programs for a mobile transceiver and a base station transceiver

Abstract

Embodiments relate to apparatuses, methods and a computer programs for a mobile transceiver (100) and a base station transceiver (200). The mobile transceiver apparatus (10) comprises means for receiving (12) radio signals from two or more base station transceivers, the means for receiving (12) further having a receive sensitivity determining a possibility to decode data from a radio signal of one of the two or more base station transceivers, while also receiving radio signals from the other of the two or more base station transceivers. The mobile transceiver apparatus further comprises means for providing (14) sensitivity information on the receive sensitivity to an associated base station transceiver (200). The base station transceiver apparatus (20) comprises means for receiving (22) the sensitivity information on the receiver sensitivity and means for determining (24) configuration information on a measurement configuration for the mobile transceiver (100). The configuration information comprises information on a signal quality measurement at the mobile transceiver (100) on radio signals received from another base station transceiver and the configuration information comprises bias information for biasing the signal quality measurement, the bias information is based on the sensitivity information.

Description

technical field [0001] Embodiments of the invention relate to mobile communications, more particularly, but not exclusively, to radio resource management in heterogeneous networks. Background technique [0002] In mobile communication networks, heterogeneous architecture becomes more and more important. A heterogeneous network (HetNet) is a network that utilizes cell types of different sizes, such as macro cells and small cells, such as macro cells, micro or pico cells and femto cells. Such cells are established by base transceiver stations for which their coverage area is determined by their transmit power and interference conditions. A small cell is a cell that has a smaller coverage area than a macro cell. In some network scenarios, the coverage area of ​​a small cell is surrounded by the coverage area of ​​a macro cell. Small cells can be deployed to expand the capacity of the network. [0003] Regarding standardization, within the 3rd Generation Partnership Project ...

AI Technical Summary

Problems solved by technology

Blank subframes may contain no transmissions from the macrocell, while "almost blank" subframes typically contain no payload data transmissions and contain little or no control signaling transmissions, but may contain reference signal transmissions to ensure compatibility with legacy terminals Backward compatibility, the legacy terminal expects to discover reference signals for measurements, but has no knowledge of the configuration of almost blank subframes
