Abstract

The embodiment of the invention relates to the field of femto networks in mobile communication, and provides a resource distribution method for suppressing cross-layer interference of a home base station to a macro base station in the femto network and meeting the requirements of heterogeneous medium users. The method comprises the following steps that: the home base station obtains the cross-layer interference gain of a home cell of the home base station to each same-frequency channel of a macro cell, and the cross-layer and same-layer interferences on the home cell; and the home base station distributes power and channels for delay tolerant users and latency sensitive users respectively based on obtained actual information.

Description

technical field [0001] The present invention relates to the field of mobile communication technology, in particular, the present invention is a kind of home base station (Home eNodeB, HeNB, femto base station, home base station) in the next generation mobile communication system (LTE / LTE-Advanced) that satisfies different users. method of resource allocation for qualitative needs. Background technique [0002] With the commercialization of the fourth-generation mobile communication system, the frequency band used by mobile communication is getting higher and higher, and the attenuation of the signal is also more serious. The macro cellular network cannot meet the user quality requirements of the increasingly high diversity of users. A typical example is the coverage of wireless networks in indoor environments. According to relevant statistics at home and abroad, 70% of voice services and 90% of data services in the 3G era occur indoors. Better indoor coverage can not only m...
