Problems solved by technology

However, the cross-carrier scheduling method in related technologies can only solve the PDCCH interference problem between the macro base station and the small base station, and the ICIC mechanism in Release 8 is only applicable to the interference problem between PDSCHs that can be dynamically scheduled, so it cannot Solve the interference problem of the PDCCH of the macro base station to the PDSCH of the small base station

Embodiment Construction

[0083] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0084] The terminology used in the present disclosure is for the purpose of describing particular embodiments only, and is not intended to limit the present disclosure. As used in this disclosure and the appended claims, the singular forms "a", "the", and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It should also be understood that the ...

Abstract

The present disclosure provides a method and a device for controlling interference, the method comprising: dividing a control region in a time domain transmission unit, to obtain a first power regionand a second power region, the transmission power of the first power region being higher than that of the second power region; dividing all current channels, to obtain a first channel group and a second channel group; transmitting data carried by all the channels included in the second channel group by means of the first power region, and transmitting data carried by all the channels included in the first channel group by means of the second power region. The present disclosure may greatly reduce interference to a PDSCH of a small cell from a PDCCH of a macro base station when the macro base station and the small cell use different parameter sets on the same carrier in a heterogeneous network, without reducing the spectrum utilization rates of the macro base station and the small cell.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and device for controlling interference. Background technique [0002] In LTE-Advanced (Long Term Evolution-Advanced, long-term evolution technology upgrade version), the main role of cross-carrier scheduling is to provide ICIC (Inter-Cell Interference Coordination, inter-cell interference coordination) support. [0003] In a heterogeneous network, such as figure 1 As shown, the macro base station and the small base station share two downlink CCs (Carrier Components, carrier components), which are assumed to be CC1 and CC2. Both CCs of the small base station work at low transmission power, CC1 of the macro base station works at high transmission power, and CC2 works at low transmission power. Especially when the range extension (RangeExtension) technology is used on the small base station, the transmission of the macro base station on CC1 in the...
