Downlink service transmission method and apparatus in CDMA system

Abstract

The invention discloses a method for transmitting downlink services in a cdma system, which relates to downlink service transmission techniques in the cdma system and is proposed for solving the problem that the present downlink service transmission is not good in the cdma system. The technical scheme which is adopted by the invention comprises: determining a service transmission mode according to district present services and communication channel resource conditions and transmitting. The invention also discloses a device for realizing the method, the technical scheme of the device is that a service transmission mode determining unit is used to determine the service transmission mode according to the district present services and the communication channel resource conditions, and a service transmission unit is used to transmit the district present services according to the transmission mode which is determined by the service transmission mode determining unit. The method and the device guarantee the present services QoS and satisfy the access demands of the services simultaneously, and the network performance is improved.

Description

technical field [0001] The present invention relates to the transmission technology of the downlink service in the code division multiple access system, and more precisely relates to the transmission method and device for setting the downlink service transmission mode in the code division multiple access system according to the channel resource and the service type. Background technique [0002] When designing any kind of cellular mobile communication system, the limited radio resources will be allocated and utilized as fully and reasonably as possible, so as to improve the capacity of the system as much as possible and provide users with better services. [0003] However, in a Code Division Multiple Access (CDMA, Code Division Multiple Access) system, since each user signal is direct interference to other users, the intra-system interference becomes a non-negligible interference source. When the base station receives the signal from the mobile station, it will be interfered...

AI Technical Summary

Problems solved by technology

[0007] 1. The quality of service (QoS, Quality of Service) and real-time performance of the CS business cannot meet the performance requirements, and there is no effective solution;

[0008] 2. Due to the high interference intensity between network users, the demodulation performance of PS services is very poor, and the block error rate is high, resulting in low transmission efficiency of service effective data, and the effective transmission rate and QoS of PS services are gradually falling short of quality Require

[0009] 3. Although the continuous transmission method can guarantee the real-time performance of PS services to a certain extent, the real-time requirements are not of great concern to PS users. Satisfying real-time performance at the expense of transmission quality is not worth the candle for PS services. , it is not very necessary
