Embodiment Construction

[0057] As mentioned in the background technology, the traditional network is a homogeneous network, and the current base station has developed to the point where the capacity of a single base station can approach the theoretical limit, and the need to obtain more gain depends on the topology of the network. Therefore, In the future, multiple wireless technologies will be deployed together in one area to increase the capacity of the entire system, and how to reduce the interference between base stations in a heterogeneous network is an important topic.

[0058] In the heterogeneous network, the inter-cell interference cancellation technology (ICIC) in the LTE system will be used. However, due to the asynchronous SFN between different cells and the introduction of ABS to eliminate the interference of the edge users of the interfered base station, then continue to use the same The inter-cell interference elimination technology in the network construction may lead to situations suc...

Abstract

The embodiment of the invention discloses a method and equipment for coordinating downlink transmitting power between base stations. By applying the technical scheme of the embodiment of the invention, the coordination of downlink transmitting power between the base stations can be carried out under the condition of fully taking the ABS configuration information of an interference base station into account, so that the downlink interference between the base stations is reduced, the throughput of a system in the downlink direction is improved, the generation of conditions of interference, and the like caused by dispatching a cell edge user by mistake through continuously using an intercell interference eliminating technology in an isomorphism network under the condition of introducing ABS is prevented, and thereby the use experience of the user is improved and the communication quality of the system is guaranteed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and equipment for coordinating downlink transmission power between base stations. Background technique [0002] With the ever-increasing data rate and service load requirements, the traditional method of providing access with single-layer coverage of macro base stations can no longer meet the requirements. Using layered coverage, deploying some low-power base stations in hot spots or indoors can solve this problem well. Common low-power base stations in the prior art include: Home eNodeB (home base station), Pico (pico cell) base station, Femto (femto cell) base station, Relay (relay), etc. This low-power base station is a base station device applied in a home indoor environment, an office environment, or other hotspot small coverage environments, enabling operators to provide attractive services with higher data rates and lower costs. [0003] In order to reduc...
