Method, device and system for setting maximum transmitting power based on RRU (Radio Remote Unit)

Abstract

The invention provides a method, a device and a system for setting a maximum transmitting power based on an RRU (Radio Remote Unit). The method comprises the following steps of: obtaining corresponding RRU type of a cell, service data information, base station configuration, predetermined maximum transmitting power of the cell and predetermined PCCPCH (Primary Common Control Physical Channel) maximum transmitting power from a database; determining the number of carriers of the cell according to the base station configuration and the service data information; determining the transmitting power of the cell according to the RRU type and the number of carriers; determining the PCCPCH transmitting power according to the RRU type and the base station configuration; and setting the maximum transmitting power of the cell according to the determined transmitting power of the cell and the predetermined maximum transmitting power of the cell. The cell with small service demands is configured with rational carriers by analyzing the service data of users in the cell, so that the maximum transmitting power of the cell and a service channel transmitting power are both improved, finally, the effect of TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) coverage is improved and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to the field of time-division synchronous code division multiple access (TD-SCDMA, time-division synchronous code division multiple access) mobile communication, specifically a method for setting the maximum transmission power based on RRU , equipment and systems. Background technique [0002] When the existing TD-SCDMA network is planned, it is uniformly configured as a macro base station, using 8-channel radio remote unit (RRU, Radio remote unit), and each cell is configured as 3 carriers. Among the 3 carriers planned for each cell, 1 is R4 (3GPP Release4 protocol) carrier, which is used as the main carrier of the cell and mainly carries signaling messages, voice services and some small traffic data services. The other two are carriers supporting the fast packet downlink data access function (HSDPA, High Speed ​​Downlink Packet Access), and each HSDPA carri...

AI Technical Summary

Problems solved by technology

[0004] The existing TD-SCDMA network adopts a unified setting. Therefore, in TD-SCDMA business hotspot areas such as urban areas, configuring three carriers in a single cell can no longer meet the normal needs of users, and it is difficult to achieve continuous coverage. to experience

In areas where TD-SCDMA traffic is small, such as urban fringes and rural areas, configuring three carriers will waste power resources

[0005] (2) The power configuration of the public channel and the business channel has not reached the maximum

[0008] That is to say, the transmit power of the common channel and service channel under the unified configuration of the existing TD-SCDMA network has not reached the maximum, so in the area where the coverage of the TD-SCDMA network is insufficient, the user experience will inevitably be reduced
