Embodiment Construction
[0034] In the following, the same reference numerals are used for objects and functional units with the same or similar functional properties, and the explanations about a certain figure are also applicable to other figures, so as to reduce the repetition when describing the embodiments.
[0035] The gain obtained by applying wireless coordination techniques, such as coordinated multipoint transmission (CoMP) or coordinated scheduling, in cellular mobile access networks depends on the condition of the wireless channel between the base station (BS) and the user terminal (UT). Depending on these channel properties, a cluster of BS cells can be selected to achieve cooperation.
[0036] In addition to wireless properties, wired backhaul and core network properties, such as link delay, capacity, and load, can also be considered when deciding how to build a cooperating cluster of cells. This is caused by the exchange of control and user data traffic that is required within the set o...

An apparatus (100) for determining a core network configuration (112) of a wireless communication system comprises cluster determiner (110). A core network of a wireless communication system comprises a plurality of base stations, a plurality of wireline links between the base stations and at least one control unit for controlling a cluster of base stations of the plurality of base stations. The cluster determiner (1 10) determines as the core network configuration (112) at least one cluster of base stations linked by wireline links and controlled by a same control unit based on a predefined basic network configuration (102), so that latencies between each base station of the cluster and the control unit of the cluster are below a maximal allowable latency. The predefined basic network configuration (102) represents information about all base stations of a core network to be configured and about possible wireline links between the base stations.
Description
technical field [0001] Embodiments according to the present invention relate to a wireless communication system, and in particular to an apparatus and a method for determining a core network configuration 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, much research has been done in the field of implementing and evaluating the performance of different cooperative techniques, 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. IEE...
