Base station cooperation sleep/rouse method and system

Abstract

The invention provides a base station cooperation sleep / rouse method. Multiple base stations provide services for cell users in a cooperation transmission manner. The sleep / rouse method includes the steps that firstly, all the base stations participating cooperation transmission send downlink channel estimation of all the base stations and / or interference and the noise level of the served users and / or power consumption parameter values of all the base stations to a central processor, wherein the downlink channel estimation comprises downlink channel characteristics from the base stations to the served users; secondly, the central processor receives the parameter information of all the base stations participating cooperation transmission, the base stations in the sleep or rouse state are determined, and notice is sent to the corresponding base stations; thirdly, the base stations which receive the notice enter sleep or rouse state according to the instruction of the notice. The invention further discloses the base station cooperation sleep / rouse system. The base station cooperation sleep / rouse method and system can give full play to potential on the energy-saving performance of the base station sleep technology.

Description

technical field [0001] The present application relates to a base station energy saving technology in a communication system, in particular to a base station cooperative sleep / wake method and system. Background technique [0002] In order to meet people's ever-increasing business needs, existing wireless communication system designs are developing towards higher data rates. However, while a communication system with high spectral efficiency brings high-speed services, it often also brings greater energy consumption. This will not only bring a greater burden to the already tense energy supply situation, but also bring many negative impacts on the natural environment and social environment. Therefore, considering multiple aspects such as sustainable utilization of energy, environmental protection, and operating costs of cellular systems, the development of energy-efficient communication technologies will become an inevitable trend in future cellular mobile communications.

Problems solved by technology

Since non-cooperative systems typically result in long wake-up times, this increases the likelihood of service disruption for users

The above factors greatly limit the application of the base station dormancy technology based on non-cooperative transmission proposed in the existing work in practical systems, thus limiting the effect of the base station dormancy technology on reducing energy consumption in cellular mobile communication systems
