Embodiment Construction

[0022] The base station cooperation of 7 cells is taken as an example for description below. Assume that in the downlink of the cooperative cellular network, each base station (BS) and mobile user (MS) are equipped with an antenna.

[0023] 1) Assuming that the system includes 7 base stations, namely base station 1, base station 2, base station 3 ... base station 7, there are 28 users MS in the system, and the 28 users are evenly distributed in 7 cells, that is, each cell has 4 users.

[0024] 2) Select a base station arbitrarily from 7 base stations. In this embodiment, base station 1 is selected, and then a base station that can form a cooperative base station set with base station 1 is selected from the remaining 6 base stations. The selection method is as follows:

[0025] One user is arbitrarily selected from the four users in the cell to which base station 1 belongs. In this embodiment, user 1 is selected. User 1 receives the pilot signals sent by base station 2 to base...

Abstract

The invention relates to a collaboration communication method for multiple cell base station dynamically clustering, which belongs to the field of wireless information transmission, such as wireless local area network, wideband radio access, mobile communication or the like. The method divides all base stations into base station clusters including few base stations, and executing collaboration communication between base stations in the same cluster. Meanwhile, customer clusters capable of collaboration communication with the base station in the base station cluster according to strength of the pilot signal to ensure accurate communication between the collaboration base station and the customer. Collaboration is effectively realized and cell system capacity is enhanced by adopting the provided method.

Description

technical field [0001] The invention is a cooperative communication method for dynamic clustering of multi-cell base stations, which belongs to the field of wireless information transmission, such as wireless local area network, broadband wireless access, mobile communication and the like. Background technique [0002] With the vigorous development of communication services, future wireless / mobile communication networks are required to support high-speed and large-capacity data, multimedia and other services. The current cellular mobile communication network adopts frequency multiplexing technology to improve spectrum efficiency, but it will lead to co-channel interference (CCI) between cells, which is also a bottleneck problem faced by the cellular system. In recent years, M.K.Karakayali, G.J.Foschini, and R.A.Valenzuela, Network coordination for spectrally efficient communication in cellular systems, IEEE Wireless Communications Magazine, vol.13, no.4, pp.56-61, Aug.2006 p...
