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...
