Carrier wave networking configuration method and system for time division-synchronization code division multiple access (TD-SCDMA)

Abstract

The invention discloses a carrier wave networking configuration method and a system for a time division-synchronization code division multiple access (TD-SCDMA) system, which are used for relieving the condition of insufficient frequency resources in the TD-SCDMA system. The performance of each type of business is balanced, and the network performance of the TD-SCDMA system is improved. The carrier wave networking configuration method for the TD-SCDMA system comprises the following steps that the carrier wave division is carried out on the available frequency bands of the TD-SCDMA system on the basis of 1.4MHz and 1.2MHz carrier wave intervals, the frequency point information of each carrier wave obtained through division is determined, and the carrier wave networking configuration is carried out on the TD-SCDMA system according to the determined frequency point information of each carrier wave and the carrier wave intervals of every two adjacent carrier waves.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a TD-SCDMA (Time Division Synchronous Code Division Multiple Access) system carrier network configuration method and system. Background technique [0002] At present, the main working frequency bands of TDD (Time division duplex, time division duplex) in my country are 1880~1920MHz, 2010~2025MHz, and the supplementary working frequency bands are 2300~2400MHz, which are called A frequency band, B frequency band and C frequency band respectively. Among them, B frequency band, And the first 20MHz (1880-1900MHz) of the A frequency band is assigned to the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) system. [0003] As one of the 3G (The 3rd Generation Mobile Communication, third generation mobile communication) standards, the TD-SCDMA system adopts the CDMA (Code Division Multiple Access, Code Division M...

AI Technical Summary

Problems solved by technology

[0008] Option 1: According to the type of service, allocate 5 carriers for R4 service, and allocate 4 carriers for HSDPA (High Speed ​​Downlink Packet Access) service; Option 1 allocates more carriers for HSDPA service, resulting in R4 service The same frequency interference is relatively large;

[0009] Option 2: According to the type of service, allocate 8 carriers for R4 service and 1 carrier for HSDPA service; Option 2 allocates more carriers for R4 service. Although the co-channel interference of R4 service is suppressed, it seriously affects HSDPA business development

[0010] In the case of using the 9-frequency scheme in the B-band, the existing carrier networking scheme is difficult to take into account both R4 services and HSDPA services, and it is difficult to balance the performance of various types of services in the TD-SCDMA system with a single-carrier transmission capacity. There is little room for performance improvement, which affects the balanced development of TD-SCDMA system

It can be seen that in the prior art, since the available frequency resources of the TD-SCDMA system are very limited, the performance of various types of services cannot be balanced, which limits the improvement of the network performance of the TD-SCDMA system
