Problems solved by technology

[0003] In the actual networking process, most cells generally do not configure the maximum rated power supported by the RRU board when configuring the transmit power, and the remaining power of the RRU board is generally wasted
At the same time, when multiple cells are configured on the same RRU, not all the cells have the same number of access users, and there is always an unbalanced load between cells caused by the difference in the number of users between cells. The data interaction in a large cell is very frequent, and the throughput used by the user is reduced, which ultimately makes the user experience worse

Embodiment 1

[0070] figure 2 This is a flowchart of the method for inter-cell power coordination in the LTE scenario in Embodiment 1 of the present invention. like figure 2 As shown, taking two cells as an example, the method includes the following steps.

[0071] Step 201, two cells Cell1 and Cell2 are established on the RRU board. The rated transmit power of the RRU board is P0, and the initial transmit powers of Cell1 and Cell2 configured by the OMMB are P1 and P2, respectively.

[0072] Step 202: Set the first threshold and the second threshold of the number of user accesses of Cell1 and Cell2 to be T1, T2 and T1', T2', respectively, where T1 is greater than T2, and T1' is greater than T2'. When the number of user accesses in the cell is higher than the first threshold, the cell is determined as the first priority cell; when the number of user accesses in the cell is between the first threshold and the second threshold, the cell is determined as the first priority cell is the sec...

Embodiment 2

[0078] image 3 This is a flowchart of a method for power cooperation between cells in an LTE scenario in Embodiment 2 of the present invention. Take two cells as an example, such as image 3 As shown, the method includes the following steps:

[0079] Step 301, two cells Cell1 and Cell2 are established on the RRU board. The rated transmit power of the RRU board is P0, and the transmit powers initially configured for Cell1 and Cell2 on the OMMB are P1 and P2, respectively.

[0080] Step 302, when configuring cells on the OMMB, directly determine Cell1 and Cell2 as the first priority cell and the third priority cell respectively according to the customized scenario of each cell.

[0081] Step 303: Allocate and adjust the transmit power of Cell1 and Cell2 according to the preset corresponding relationship between priority and transmit power allocation. The transmit power allocated by Cell2 is the real power P2' after the power suppression configuration parameter of the cell o...

Abstract

A method and device for inter-cell power cooperation in an LTE scenario, the method comprising: determining the priority of each cell according to the number of user accesses in each cell or a customized scenario; according to a preset priority and transmit power The corresponding relationship of allocation is to allocate transmit power to each cell; according to the transmit power allocated to each cell, the transmit power is scheduled for each cell, and the device includes: a base station side priority confirmation unit, a base station side Power allocation unit and base station side power scheduling unit. The invention allocates the rated transmit power supported by the RRU single board to each cell according to the corresponding relationship between the priority and the transmit power allocation, and performs scheduling, so as to realize the full use of the rated transmit power supported by the RRU single board without waste, and can Realize dynamic optimization of allocation to each cell, improve load imbalance between cells, and achieve the effect of improving user experience.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method and device for inter-cell power cooperation in an LTE scenario. Background technique [0002] LTE (Long Term Evolution, Long Term Evolution) is the long-term evolution of the UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) technical standard formulated by the 3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) organization. In the LTE scenario, the maximum rated transmit power supported by the RRU (Radio Remote Unit) board is fixed and determined by the model. The base station side can query the rated transmit power supported by the RRU board model of different styles, and configure the initial transmit power of the cell through the OMMB (operation and maintenance center). [0003] In the actual networking process, when configuring the transmit power in most cells, th...
