Embodiment 1

[0094]The embodiment of the present invention provides a method for allocating network resources, which can be applied to wireless communication networks. Due to the shortage of resources caused by the rapid increase in the number of mobile devices and applications, new resources need to be developed, and network resources need to be re-allocated. In a specific application scenario, the network resource allocation method in this embodiment, such as figure 2 shown, including:

[0095] Step S11: Receive a downlink reference signal from a base station. In this embodiment, the base station (BaseStation, BS) is an indispensable part of the LTE-U system, and the base station is a public mobile communication base station, which is a form of radio station, and refers to a certain radio coverage area. The mobile communication switching center is a radio transceiver station that transmits information between the user equipment; the base station communicates with the user equipment thr...

Abstract

The embodiment of the invention discloses a network resource allocation method and device. The method is applied to an LTE-U system, and comprises the following steps: receiving a downlink reference signal from a base station, obtaining the signal to interference plus noise ratio of different subcarriers of user equipment on each carrier component, and converting to obtain the equivalent signal tointerference plus noise ratio of the user equipment on the carrier component; obtaining the channel quality of the user equipment on the carrier component according to a preset mapping relationship,and clustering the user equipment according to the channel quality and the position feature information of the user equipment to obtain multiple types of user equipment; and judging whether the various user equipment is interfered by the Wi-Fi system, and finally allocating network resources used by the various user equipment. By implementing the method and the device, the problem that the networkresource allocation is influenced due to the hidden terminal problem in the prior art is solved, and the optimal network resource allocation scheme is obtained to ensure the service quality requirement of a user.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for allocating network resources. Background technique [0002] With the rapid growth of the number of mobile devices and the number of applications, the limited licensed spectrum in the existing cellular network is difficult to meet the current demand for mobile data services. In addition, because licensed spectrum is very scarce and expensive, operators have proposed Long Term Evolution-Unlicensed (LTE-U), which aims to alleviate the pressure on mobile communications through a large number of available resources on unlicensed spectrum. LTE-U uses existing carrier aggregation technology to aggregate licensed and unlicensed frequency bands to provide larger coverage area and network capacity. However, since LTE-U and Wi-Fi systems use different unlicensed channel access mechanisms, the introduction of LTE-U will seriously affect the performance o...
