Dispatching method for high speed data transmission in mobile communication system

Abstract

This invention discloses method for managing high-speed data transmission in a mobile communication system to realize a joint-scheduling for uplink and downlink. The invention comprehensively utilized the relevant information of uplink and downlink, such as the user transmission speed information of scheduling process, load information of the uplink and CQI information of downlink scheduling process, user transmission speeds, downlink code resources and power resources information etc. to schedule the uplink and downlink comprehensively and realize a reunified scheduling by using the same resources, and to adjust uplink and downlink transmission rates simultaneously.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a high-speed data transmission technology in the third generation mobile communication (The Third Generation, referred to as "3G") evolution technology. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP"), as an important organization in the field of mobile communications, has promoted the standardization of 3G technology. In its early protocol versions, the bearer of uplink and downlink services is based on dedicated channels. Among them, in the R99 version (Release 99, referred to as "R99"), the uplink and downlink data transmission rates that can be achieved are both 384 kilobits per second (Kbps). [0003] With the development of mobile communication technology, 3G technology is also constantly evolving. Many data services that require high traffic and delay, such as video, streaming media,...

Problems solved by technology

[0016] In practical application, the above-mentioned solution has the following problems: the existing technical solution will cause waste of resources, and is not conducive to guaranteeing the transmission rate of the user, cannot guarantee the quality of service (Quality of Service, referred to as "QoS") of the user, and is used simultaneously in the user business These problems are more serious when using HSDPA and HSUPA, especially when the cell supports a large number of users

[0017] The main reason for this situation is that the existing technical solutions independently perform uplink and downlink scheduling, without comprehensive consideration of uplink and downlink service conditions, which may cause a mismatch between the user's uplink and downlink data transmission rates, and cannot guarantee the user's QoS

At the same time, since the uplink and downlink scheduling information is not comprehensively used to optimize data transmission, the user's transmission rate cannot be better guaranteed, and the fast scheduling of uplink and downlink for the same user increases the consumption of scheduling resources, resulting in a waste of system resources , especially when the number of users supported by the cell is large, and the resource requirements for multi-cell user scheduling are relatively high, if the fast scheduling of the uplink and downlink base stations is performed independently, it will cause a relatively large waste of resources and cannot make full use of the small delay. and the benefits of higher data transfer rates
