Problems solved by technology

HSUPA can make full use of the UE's transmit power resources to maximize the transmission of packet services. Since the uplink is limited by interference, if the uplink interference exceeds a threshold, the performance of the uplink channel will be greatly reduced

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and the embodiment of HSUPA Node B scheduling control.

[0028] attached figure 1 The overall flowchart of HSUPA performing uplink power control is illustrated. In this example, UE110 transmits E-DCH to Node B120, and Node B120 reports E-DCH transmission information such as PDU transmission times and block error rate BLER to RNC130, and then RNC130 adjusts the power offset in the HARQ Profile of UE110 , and reconfigure the power offset of the E-DCH to the UE 110 by sending an RRC command.

[0029] At the same time, Node B120 monitors the uplink RoT of the cell. When the predetermined threshold is reached, that is, the load of the cell has risen to a certain level, it is necessary to allocate system resources more finely, and enter the Node B120 scheduling adjustment stage. Node B120 judges whether the current resource utilization efficiency of UE110 is appropr...

Abstract

The invention is concerned with the controlling method that can improve the bounding resource utilization efficiency in the radio communication system, it is: Node B monitoring station controller configures the shell power migration of the user's equipment, estimates the resource utilization efficiency whether or not fit for the current user's equipment, makes the decision to adjust the bounding transmission format of the user's equipment if it is not fit.

Description

technical field [0001] The invention relates to a control method for improving uplink resource utilization in a mobile communication system, in particular to a Node B scheduler for an uplink enhanced channel (E-DCH) in a WCDMA system. Background technique [0002] In the HSUPA (High Speed ​​Uplink Packet Access) of the WCDMA standard R6, in order to provide faster resource scheduling and more flexible scheduling algorithms, the Node B control scheduling strategy is adopted. The scheduling implemented in Node B belongs to distributed scheduling, and the impact of UE (User Equipment) on other adjacent cells cannot be considered, and WCDMA is a self-interference system, the uplink resource capacity is limited and the total power received by the receiver at Node B . When the cell load increases to a certain extent, the relationship between cell interference and throughput growth is exponential, that is to say, in the case of high load, increasing the same system throughput requ...
