Embodiment Construction

[0035] Figure 4 A block diagram illustrating an apparatus for determining a control unit of a plurality of control units for controlling coordinated transmission or coordinated reception between a base station and a wireless device in a wireless communication system comprising a plurality of control units A wired backhaul network, and multiple base stations, where each control unit is capable of controlling one or more base stations.

[0036] The device comprises a cluster feasibility processor 400 configured to receive a cluster feasibility response 401 from at least one other control unit than the control unit controlling the base station actually serving the wireless device. The cluster feasibility response contains information of feasible wired clusters of base stations controllable by said at least one other control unit sending the feasibility response. Preferably, the other control unit delivered the cluster availability request 400 reacts to the availability request ...

Abstract

An apparatus for determining a control unit of a plurality of control units in a wireless communication system for controlling a cooperative transmission or a cooperative reception between base stations and a wireless device, wherein the wireless communication system comprises a wireline core network with a plurality of control units and a plurality of base stations, wherein each control unit is able to control one or more base stations. The apparatus comprises a cluster feasibility processor (400) configured to receive a cluster feasibility response from at least one other control unit than a control unit controlling a base station serving a wireless device containing information of a feasible wireline cluster of base stations controllable by the at least one other control unit; and a control unit selector (403) configured to select the at least one control unit for controlling a cooperative transmission or a cooperative reception between at least two base stations and the wireless device based on the at least one received information of the feasible wireline cluster of base stations controllable by the at least one other control unit.

Description

technical field [0001] Embodiments according to the present invention relate to a wireless communication system, and in particular to a device and a method for determining a core network structure of the wireless communication system. Background technique [0002] Coordination in cellular mobile access networks shows large benefits in terms of radio transmission capacity, inter-cell interference management, and energy consumption. Several techniques have been proposed so far (joint precoding and decoding, inter-cell coordination, etc.), which respectively improve different performance indicators. [0003] From a wireless point of view, there has been much research in the field of implementing different cooperative techniques and evaluating their performance, such as joint signal processing (“V. Jungnickel, L. Thiele, T. Wirth, T. Haustein, S. Schiffermüller, A. Forck, S. Wahls, S. Jaeckel, S. Schubert, H. 'Coordinated multipoint trials in the downlink', Proc. IEEE Broadba...
