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...
