Embodiment Construction

[0057] The following is an explanation of some words that appear in the text:

[0058] 1. The "terminal" referred to in the embodiment of the present invention is a mobile phone, a platform, etc.

[0059] 2. The "network side device" referred to in the embodiment of the present invention is a macro base station, a micro base station, and the like.

[0060] 3. "And / or", which describes the association relationship of associated objects, means that there can be three kinds of relationships, for example, A and / or B, which can mean: A exists alone, A and B exist simultaneously, and B exists alone. . The character " / " generally indicates that the contextual objects are an "or" relationship.

[0061] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0062] Such as figure 1 As shown, a method and device for interference coordination include: a terminal 10 and a network side device 20 .

[0063] Ter...

Abstract

The present invention provides a method and equipment for interference coordination, which are used to solve the problem in the prior art that centralized interference coordination requires a large amount of information exchange, resulting in huge signaling overhead. In the embodiment of the present invention, the terminal sends the interference information of the current time slot and / or the QoS requirement value of the next time slot to the network side device, and the network side device receives the interference information of the current time slot corresponding to the terminal and / or the next time slot Adjusting the transmission parameters for the terminal in the next time slot according to the QoS requirement value of the next time slot. In the embodiment of the present invention, the network-side device does not need to send the information reported by the terminal and the channel state information between all network-side devices that interfere with the terminal and the terminal to the central node for centralized processing, avoiding a large amount of information Switching saves signaling overhead.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for interference coordination. Background technique [0002] With the rapid development of communication technology, 5G networks are becoming more and more dense. In order to realize the effective allocation of spectrum resources, operators cooperate with management equipment and spectrum allocation equipment to realize spectrum resource sharing. The dense overlapping coverage caused by spectrum resource sharing The multi-layer heterogeneous network causes interference among a large number of cells, which restricts the system performance. [0003] From the perspective of the source of inter-cell interference, the interference from adjacent base stations is the main component of inter-cell interference. At present, a centralized interference coordination scheme is mainly used to effectively avoid inter-cell interference. The centralized interference coord...
