Embodiment Construction

[0050] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0051] The method for adjusting the transmission power of almost blank subframes provided by this application can be applied to such as figure 1 shown in the application environment. Among them, the macro base station 110 is an interference source base station; the micro station 120 is an interfered base station, which can be a pico cell, a home base station, and a relay node; the communication process between the macro base station 110 and the micro station 120 is as follows figure 2 As shown, the macro base station 110 sends the almost blank subframe pattern to the mic...

Abstract

The present application relates to a method, system, computer equipment and storage medium for adjusting the transmit power of almost blank subframes. The method includes: acquiring location indication information of the micro-station, resource utilization of almost blank subframes fed back by the micro-station, and user equipment measurement information; Coverage determination; if it is determined that the location of the micro station is within a weak coverage area, adjust the macro station on the almost blank subframe according to the resource utilization rate of the almost blank subframe and the measurement information of the user equipment. transmit power. The method can avoid the influence of unnecessary transmission power adjustment on the performance of the micro-station, and adjust the transmission power of the almost blank subframe in combination with the resource utilization rate of the almost blank subframe and the measurement information of the user equipment, so that the transmission power of the almost blank subframe is The adjustment is more accurate, and the resource utilization rate of the system is effectively improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method, device, computer equipment and storage medium for adjusting transmission power of almost blank subframes. Background technique [0002] LTE (Long Term Evolution, long-term evolution) network In order to effectively solve the problems of macro station coverage increase and distribution in indoor and hotspot scenarios, LPN (Low Power Node, low power node) is introduced into the macro station coverage area to form different types of nodes A multi-layer network with the same coverage, the industry calls such a network HetNet (Heterogeneous network, heterogeneous network). The LPN includes a pico cell (Pico cell), a home base station (Femto cell) and a relay node (Relay Node), and the LPN here may also be collectively referred to as a micro station. [0003] In a heterogeneous network, edge users of micro-stations are often subject to severe co-...
