Problems solved by technology
Due to the large difference in transmit power between base stations on different layers, the interference between cells on different layers is often more serious than the interference between cells on the same layer, which will seriously affect the throughput of the system.

Embodiment Construction
[0066] The specific implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings (the same symbols in several drawings represent the same elements) and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.
[0067] A common interference scenario in a heterogeneous network is a hybrid interference scenario, such as figure 1 As shown: the downlink data signal sent by the macro base station to the user equipment of the macro base station will cause strong interference to the user equipment of the micro base station, and at the same time, the downlink data signal sent by the micro base station to the user equipment of the micro base station will cause strong interference to the user equipment of the macro base station Weak interference. Due to various small-scale fading, such a scenario may occur regardless of the locati...

The embodiment of the invention provides a multi-carrier data transmission method, an interference elimination method, a multi-carrier data transmission device and an interference elimination device. The multi-carrier data transmission method includes the steps that desired signals are sent to user equipment of a first base station through first-type sub-carriers, and the interference signals which show that the first base station interferes with user equipment of a second base station are sent to the user equipment of the first base station and the user equipment of the second base station through second-type sub-carriers. According to the multi-carrier data transmission method, the interference elimination method, the multi-carrier data transmission device and the interference elimination device, the interference signals can be sent through the second-type sub-carriers, the interference signals can be received by the user equipment of the second base station, and then the interference signals are eliminated. The interference signals also can be received by the user equipment of the first base station and used for decoding the desired signals, and then interference elimination in a mixed interference scene in a heterogeneous network can be achieved.
Description
technical field [0001] The present application relates to the technical field of heterogeneous networks, and in particular to a multi-carrier data transmission method, an interference elimination method, a multi-carrier data transmission device, and an interference elimination device. Background technique [0002] With the rapid development of mobile communication technology, various mobile Internet services that require high data rate support are booming. However, in recent years, the coverage area of cellular cells has become smaller and smaller, and due to the uneven distribution of users, the traditional cell splitting technology that can improve the spatial capacity of cellular networks has been unable to meet actual needs. [0003] As a new type of cell deployment scheme, Heterogeneous Network (HetNet) refers to the deployment of various low-power small base stations (micro base stations) inside the macro cell covered by the macro base station (Macro-BS), including: ...
