Method for realizing balanceable up and down going coverage between adjacent base stations

Abstract

The invention users a simple approach to balance the uplink coverage and downlink coverage in a single type base station networking as well as reducing the cost of networking. Wherein, a process for reducing the sensitivity of cell is made for the base station to reduce the coverage of uplink so as to implement the coverage balance in uplink and downlink.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a base station coverage adjustment technology in the field of mobile communication. Background technique [0002] Mobile communication has greatly changed people's lives, and with the development of mobile communication and the growth of communication demands, users' requirements for mobile network quality are also increasing day by day. In the field of personal mobile communication, which is the most widely used in mobile communication, the cellular mobile system occupies a dominant position. The cellular mobile system divides the entire service area into several cellular sub-coverage areas, called cells or cells (Cell), and each cell is covered by a transceiver, which is called a base station (Base Station, "BS" for short), and the users in the entire cell complete communication with this base station. Since the same frequency can be used in different cells, mobile communica...

Problems solved by technology

[0019] In practical applications, the above solutions have the following problems: Technical solution 1 affects switching performance and has limited application scenarios; Technical solution 2 has high cost and limited improvement effect, and is rarely used

[0020] The main reason for this situation is that the existing technical solution 1 increases the downlink coverage of the micro cell, and the setting of the CIO parameter makes the receiving power of the two cells unequal when the UE is handed over, which will cause a decrease in the success rate of the handover. This solution is only used for serious problems such as corner effects, and the application scenarios are limited

[0021] Solution 2 of the existing technology requires more antenna diversity, which will increase the difficulty of signal processing. At the same time, the increase in the number of antennas will also significantly increase the cost of hardware, and because the improvement of antenna diversity is limited, when the number of diversity When there are more, the effect of adding antennas to improve is also very limited, so it is rarely used
