Problems solved by technology

But this adjustment is not real-time, and the link bandwidth will remain stable for a long time
This bandwidth allocation strategy can prevent the amount of uplink data from exceeding the uplink capacity, and also better meet the bandwidth requirements of services such as voice and video. However, when processing data services, due to the suddenness and unevenness of the traffic A fixed allocation strategy will cause waste of bandwidth and unnecessary transmission delay

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, all uplink bandwidth of the mobile station 102 is controlled and allocated by the base station 101, the mobile station 102 submits the rate application information 103 to the base station 101, the base station 101 transmits the rate indication information 104 to the mobile station 102, and the mobile station 102 sends uplink data according to the instruction 104 105.

[0022] Such as figure 2 As shown, the system implementation is divided into five units: the rate adjustment unit 204 of the base station 208, the real-time channel allocation unit 203 and the integrated control unit 205, the measurement unit 201 and the rate application unit 202 of the mobile station 207. The allocation process can consist of the following three steps.

[0023] 1. The measurement unit 201 of the mobile station 207 measures the size of the sending b...

Abstract

This invention is related to a control method of up packet transmission rate is CDMA communication system. The bandwidth allocation of this invention is adopted by presenting application by the mobile station and contralization allocation of the base station in which the strategy of allocation is to combine two methods of allocation based on data packet and dynamic rate adjustment not only avoiding data collision resulted in the quantity of up data surpassing the up capacitance but also reducing transmission time delay of accident data operation and to finely classify different types of operation to adopt different method to rectify different transmission rate to use the up band width to the utmost and secure the justness in mobile stations.

Description

technical field [0001] The invention relates to a data transmission method using a code division multiple access (CDMA) communication system, in particular to the rate control of uplink packet transmission in the CDMA communication system. Background technique [0002] The uplink transmission of a general CDMA system is a self-interference system. The interference on the reverse link is mainly caused by the superimposition of signals from other mobile stations in the base station receiver, that is, the interference caused by the uplink data signals sent by other mobile stations, so the uplink capacity of the CDMA system is generally smaller than the downlink capacity. If the amount of data sent uplink by the mobile station exceeds the designed uplink capacity, all uplink data cannot be correctly received by the base station. [0003] The third generation CDMA cellular communication system, including WCDMA and CDMA2000, WCDMA introduced in "RRCProtocol Specification 3GPP TS ...
