Problems solved by technology

This reconfiguration method has a weakness, that is, the reconfiguration message is sent along with the service channel, and the message still follows the parameter requirements of the original service configuration during baseband processing, so when the channel fades, the reconfiguration The message may not be correctly parsed at the receiving end, resulting in a complete error in the downlink / uplink reception service channel, and the base station and terminal cannot communicate correctly, which seriously affects the robustness of the service channel transmission

Embodiment Construction

[0012] The present invention proposes a method, that is, when the base station continuously receives uplink service errors, or the base station continuously receives downlink service reception error feedback from the terminal, timely adjusts the parameter requirements of service configuration, and uses a dedicated downlink channel to Send the reconfiguration request of the service configuration.

[0013] When the base station continuously receives uplink service errors, the base station can adjust the uplink service configuration parameters alone, or adjust the downlink and uplink service configuration parameters at the same time; when the base station continuously receives downlink service reception error feedback from the terminal, the base station needs to adjust the downlink service configuration parameter.

[0014] The mapping relationship between the dedicated downlink channel and the physical subchannel is completed and fixed by the base station during system configurat...

Abstract

The invention provides a method capable of reliably sending service reconfiguring information in time when channel conditions are poor, thereby the method enables terminals to correctly adjust serviceconfiguration parameters in time to ensure the stability of service transmission.

Description

technical field [0001] The invention relates to a method for ensuring robustness of service transmission in a wireless communication system. Background technique [0002] In a wireless communication system, the characteristics of the channel are determined by the radio wave propagation environment, and the propagation environment itself is quite complicated, which makes the characteristics of the wireless channel very complicated. Especially in mobile wireless channels, signal fading (that is, a sudden drop in signal strength) often occurs. [0003] When the base station and the terminal need to communicate, the base station will set a certain service configuration according to the current channel conditions, and then send it to the terminal. Send traffic channel. When channel conditions change, the original service configuration may need to be readjusted, such as reducing the modulation order or code rate, and using the most reliable modulation and coding methods to ensur...
