Abstract

There are provided measures for cell clustering based configuration of flexible time division duplex communication, such as e.g. in layered heterogeneous network deployments. Such measures may exemplarily comprise measures for specifying a desired uplink-downlink configuration for time division duplex communication in a subject cell of a cellular communication system, obtaining at least one desired uplink-downlink configuration for time division duplex communication in at least one neighboring cell of the cellular communication system, wherein the at least one neighboring cell and the subject cell belong to the same cell cluster, and defining an uplink-downlink configuration for time division duplex communication in at least the subject cell of the cell cluster out of a set of predefined uplink-downlink configurations with flexible subframe patterns for flexible time division duplex communication on the basis of the specified desired uplink-downlink configuration for the subject cell and the obtained at least one desired uplink-downlink configuration for the at least one neighboring cell.

Description

technical field

[0001] The present invention relates to a cell cluster based configuration for flexible time division duplex communication. More specifically, the present invention relates to measures (including methods, apparatus and computer program products) for cell cluster-based configuration for, eg, enabling flexible time-division duplex communication in hierarchical heterogeneous network deployments. Background technique

[0002] In the field of communication systems (including wireless and / or cellular communication systems), various techniques are known for using physical channels for both transmission and reception operations, i.e., from the point of view of the system entity in question, for Transmit and receive direction communication. One of these known channel utilization techniques is Time Division Duplexing (TDD), in which transmit and receive operations use a common frequency spectrum while being separated in time from each other.
