Problems solved by technology

[0009] The technical problem to be solved by the present invention is to provide a method for realizing the characteristics of high-speed uplink packet access, so as to overcome the buffer overflow caused by queue stagnation that prevents correctly received data from being sent upward, and the reordering function that requires a large amount of buffer resources. The implementation complexity of the wireless network controller is greatly increased, etc.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and system for realizing high-speed uplink packet access characteristics, which are applied to a time division code division multiple access system. Background technique [0002] In the third-generation mobile communication system, in order to provide higher-speed uplink packet services and improve spectrum utilization efficiency, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) introduced the WCDMA and TD-CDMA system specifications High Speed ​​Uplink Packet Access (HSUPA: High Speed ​​Uplink Packet Access) feature, that is, the uplink enhanced feature. In the HSDPA feature, by introducing Adaptive Modulation and Coding (AMC: Adaptive Modulation and Coding), Hybrid Automatic Retransmission Request (HARQ: Hybrid Automatic Retransmission Request) and scheduling technology controlled by Node B (Node B), the network processing delay is redu...
