Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention 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 invention, not to limit the present invention.

[0049] An embodiment of the present invention provides a resource management method, such as figure 1 As shown, the method includes the steps of:

[0050] S110, the base station obtains the comprehensive OI level information received by the users in the current sector in the RB segment occupied by the adjacent sector within the statistical window length;

[0051] There are K sectors in the network, and each sector sends OI level information of its own sector to all adjacent sectors, and simultaneously receives OI level information sent by base stations in other adjacent sectors. In this embodimen...

Abstract

A resource management method is provided, and includes: a base station, acquiring an integrated Overload Indication (OI) level information of the adjacent sectors within a statistic window received by a user from a radio bearer RB which is currently occupied in a local sector; acquiring a Quality of Service (QoS) satisfaction of the user; acquiring a ratio of the time when the user occupies the RB segment in a statistic window; performing power adjustments with different step lengths for the user according to the integrated OI level information of the adjacent sectors within the statistic window received by the user from the radio bearer RB which is currently occupied, the QoS satisfaction of the user, the ratio of the time when the user occupies the RB segment in a statistic window. A base station using the above method is also provided. With the present invention, the problem of performance loss caused by performing power adjustments only utilizing the historical resource scheduling information and the indication of OI level information of the user is solved, and the performance of the power adjusting is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a resource management method and a base station. Background technique [0002] The LTE (Long Term Evolution) uplink physical layer adopts SC-FDMA (Single-carrier Frequency Division Multiplexing), so that the service signals between users belonging to the same cell are kept orthogonal, thereby avoiding the same Users in the cell interfere with each other to ensure the accuracy of service signal transmission and reception. However, since the frequency reuse factor is one, that is, all cells within the coverage of the entire system use the same frequency band to provide services for users in this cell, the interference between cells still exists, especially for edge users. interfering. The frequency division multiplexing technology cannot eliminate the interference between users in adjacent cells, so reducing the interference between cells as much as possible becomes the ke...
