Method and system for improving uplink capacity of remote radio unit (RRU) merged cell

Abstract

The invention discloses a method and system for improving uplink capacity of a remote radio unit (RRU) merged cell. The method comprises the following steps: multiple RRUs are connected to a baseband processing unit (BBU) of a base station, and the RRUs form a logic cell; the multiple RRUs report RTWP values of each sector at the same frequency point to the BBU unit through an Ir interface; the BBU reports the RTWP values of all sectors at the same frequency point under the logic cell to an RNC through a non-standard Iub interface; and the RNC receives the RTWP value of each sector at the same frequency point under the logic cell and a ground noise value of each sector under the logic cell, calculates the RoT of all sectors under the logic cell, and controls the uplink capacity of each sector according to the RoT of each sector and an RoT threshold. Thereby, the problem that part of the sectors have relatively large uplink capacity and other sectors cannot be accessed or have poor experience in case that the multiple RRUs are merged to the logic cell can be solved, and the uplink capacity of the multi-RRU merged cell can be improved.

Description

[0001] 【Technical field】 [0002] The present invention relates to a technique for merging cells of radio remote units, more precisely, a method and a system for improving uplink capacity when multiple WCDMA remote radio units merge cells. [0003] 【Background technique】 [0004] With the development of mobile data services, issues such as signal coverage and network capacity have become increasingly concerned topics for mobile network operators. [0005] The existing technology adopts a multi-channel networking solution of BBU (Baseband Unit, baseband unit) + RRU (Remote Radio Unit, radio frequency remote unit), which can quickly and effectively solve problems such as deep network coverage. The BBU has the function of sharing baseband resources, and the RRU is responsible for the function of sending and receiving signals to realize the communication between the wireless network system and the mobile station. [0006] Fiber optic connections are usually used between the BBU an...

Problems solved by technology

In the traditional solution, in order to simplify the processing, on the baseband side, compare the RTWP measurements of all sectors in the same logical cell, and take the largest RTWP value and report it to the RNC, such as figure 1 As shown, in this way, when the uplink capacity of some sectors is relatively large, other sectors will not be able to access or the service experience will be poor.
