Problems solved by technology

The problem of inter-cell interference in the dense cell deployment scenario is more prominent and serious than that in the macro network deployment scenario. However, through distributed signaling interaction, the demand for signaling transmission is large, causing the interface between cells to be overloaded, and because many nodes are involved, distributed interference coordination algorithm and effect will not be very good

specific Embodiment approach

[0060] In the first specific implementation manner, for each adjacent cell, the first weight factor a is calculated 1 The product of the load of the adjacent cell in the basic frequency resource, and the second weight factor a 2 and the sum of the products of the adjacent cell's interference to the cell in the basic frequency resources to obtain the single-cell frequency point priority coefficient of each adjacent cell to the cell;

[0061] Calculating the weighted sum of the single-cell frequency priority coefficients of each of the adjacent cells to obtain the frequency priority coefficient I of the basic frequency resource Rseg .

[0062] In a specific implementation, the product of the single cell frequency point priority coefficient of each adjacent cell and the weight coefficient corresponding to the adjacent cell is calculated and summed to obtain the frequency point priority coefficient I of the basic frequency resource Rseg .

[0063] Among them, within the basic f...

no. 1 Embodiment

[0140] The first specific embodiment, as attached Figure 6 As shown, the specific process of requesting by the base station to allocate frequency resources for a newly opened cell is as follows:

[0141] In this specific embodiment, when the base station starts up or starts a cell under the base station, it sends a request to the centralized node, and the centralized node allocates frequency resources for the newly activated cell.

[0142] Step 601: the base station establishes a connection with the network, and reports the frequency point and bandwidth capability information to the centralized node.

[0143] Step 602: Optionally, if the centralized node can determine the basic information of the adjacent cell of the newly opened cell, notify the base station of the basic information of the adjacent cell, the basic information of the adjacent cell is mainly the frequency point information of the adjacent cell .

[0144] Step 603: The centralized node determines and maintain...

specific Embodiment 6

[0225] Specific embodiment six, the centralized node allocates frequency resources with the least interference and / or the least load to different cells. In this specific embodiment, the influence of the central frequency band is not considered, and frequency resources are allocated to newly accessed cells according to the principle of minimum interference within the bandwidth. .

[0226] For example, if the width of the basic frequency resource is 2.5MHz, and a bandwidth resource of 5MHz is allocated to the newly accessed cell, the frequency point priority coefficients of the basic frequency resources Rseg1, Rseg2, and Rseg3 are IRseg1=0.2, IRseg2=0.2, and IRseg3, respectively. =0.3, adjacent cells have already used frequency band resources (Rseg1+Rseg2) and frequency band resources (Rseg2+Rseg3), according to the principle of minimum interference and / or minimum load, regardless of whether the central frequency band overlaps, allocate frequency band resources for newly accessed...

Abstract

The invention discloses a method for configuring base station frequency resources, which is used to realize reasonable configuration of base station frequency resources and avoid or reduce inter-cell interference. The method includes: determining each basic frequency resource in each permitted working frequency band of the cell conforming to an optional working bandwidth; determining a frequency point priority coefficient of each basic frequency resource, and the frequency point priority coefficient characterizes the The interference caused to the cell by the adjacent cells adjacent to the cell in the basic frequency resource, and / or the load of the adjacent cells in the basic frequency resource; according to the basic frequency resource The frequency point priority coefficient of , and allocate frequency resources for the cell. The invention also discloses a network device.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a base station frequency resource configuration method and network equipment. Background technique [0002] In a wireless communication system, signals propagate through the wireless environment. Under the deployment of multiple access points (such as base stations in cellular networks and access points (Access Points, APs) in wireless local area network (WLAN) systems), if adjacent access points The points use the same working frequency, which will cause adjacent cell interference in most systems (such as Orthogonal Frequency Division Multiplexing (OFDM) system, Code Division Multiple Access (CDMA) system), resulting in spectrum resources not being able to It is effectively used to reduce the transmission performance of the wireless system. [0003] Taking the OFDM system as an example, the Long Term Evolution (LTE) system is a fourth-generation (4G) wireless com...
