Inter-frequency measurements in hetnet based on the velocity of a mobile device

Abstract

Embodiments provide apparatuses, methods and computer programs for a mobile transceiver and a base station transceiver, a mobile transceiver, a base station transceiver and a mobile communication system. The apparatus (10) for the mobile transceiver (100) in a mobile communication system (300) comprises means for receiving (12) information on a periodic measurement configuration for an inter-frequency measurement from a base station transceiver (200, 305) of the mobile communication system (300) on a first frequency layer. The inter-frequency measurement refers to a repetitive measurement on a second frequency layer with a repetition cycle, which is such that the mobile transceiver (100), when moving at a velocity below a velocity threshold, is located in a coverage area of another base station transceiver (315) on the second frequency layer for at least two repetition cycles. The apparatus (10) further comprises means for measuring (14) a radio signal on the second frequency layer based on the information on the periodic measurement configuration to obtain an inter-frequency measurement result, and comprises means (16) for reporting information on the inter-frequency measurement result to the base station transceiver (200, 305) of the mobile communication network (300), when the inter-frequency measurement result fulfills a threshold criterion. The base station transceiver apparatus (20) comprises means (22) for providing the information on the periodic measurement configuration for the inter-frequency measurement to the mobile transceiver (100) and means for receiving (24) the information on the inter-frequency measurement result from the mobile transceiver (100).

Description

technical field [0001] Embodiments of the present invention relate to wireless communications, more particularly but not exclusively to inter-frequency measurements between multiple frequency layers of a mobile communication system. 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, for example, macro cells, pico cells, and femto cells. Such a cell is established by a base transceiver station whose coverage area is determined by its transmission power and interference conditions. Picocells and femtocells are cells that have a smaller coverage area than macrocells. In some network scenarios, the coverage area of ​​a small cell may be surrounded by the coverage area of ​​a macro cell. Small cells can be deployed to expand network capacity. Regarding standardization, in the 3rd Generation Partnership Pro...

Problems solved by technology

Because the cells or base stations in such a network can utilize the same frequency resources, such an architecture suffers from interference caused by the overlapping coverage areas of these cells
