Problems solved by technology

If the AG / RG command cannot be received correctly, the system will be overloaded or idle resources will be wasted, which will affect the scheduling fairness among UEs, system scheduling efficiency and system performance
[0008] Error correction can use the AG or RG command to resend the authorization. AG can specify any authorization, but AG belongs to the public channel and has a high transmission power; although RG can only increase or decrease a step size based on the original authorization of the UE, it belongs to Dedicated channel, low transmit power

Embodiment Construction

[0037] The main idea of ​​the present invention is: by judging the relationship between the UE's current use authorization and allocation authorization, adjust UEs that exceed the allocation authorization or are lower than the allocation authorization and are in an unsatisfactory state, thereby avoiding system overload or resource idleness.

[0038] The implementation process of the adjustment method of the present invention will be described in detail below by taking a cell including 5 users as an example.

[0039]As shown in Figure 1, the RNC is connected to multiple base stations, each base station covers several cells, each cell has several UEs, and each base station has a scheduler (not shown in the figure). There are 5 UEs in cell 3, and the scheduler assigns SG_Sch 20 to the 5 UEs according to the current load conditions. After each UE receives the scheduling command from the scheduler and the scheduling command takes effect, the scheduler accepts the data sent by the UE...

Abstract

The invention discloses a method of uplink load control correction, which comprises setting an allocation grant in each user equipment, analyzing the enhanced transport format combination index (ETFCI) value, transmission times and user satisfaction value of each user equipment by a base station, judging whether the retransmission times of the user equipment is zero for each user equipment, if yes, calculating the servicing grant of the user equipment based on the ETFCI, if the allocation grant of user equipment is smaller than the servicing grant, reducing the servicing grant of the user equipment down within the threshold of allocation grant and stopping the current treatment process; otherwise, regulating the servicing grant of the user equipment within the threshold of allocation grantbased on the user satisfaction value. The invention also discloses a relevant device for regulating the servicing grant of the user equipment based on the relationship between the servicing grant andthe allocation grant. The invention improves the scheduling fairness among UE, the system scheduling efficiency and the system performance, regardless of scheduling strategy, and can be well used ineach HSUPA scheduling algorithm.

Description

technical field [0001] The invention relates to uplink load control technology, in particular to an uplink load control error correction method and device. Background technique [0002] Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) system is a broadband cellular wireless communication system based on Code Division Multiple Access (CDMA, Code Division Multiple Access). WCDMA system supports more types of services and higher data rates Business transmission capability. High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) is a technology to enhance the uplink transmission capability of the WCDMA system. HSUPA technology mainly includes shorter transmission time interval (TTI, Transmission Time Interval), and a scheduler based on Node B of the base station and Hybrid Automatic Retransmission reQuest (HARQ, Hybrid Automatic Retransmission reQuest), because the new transmission channel (E-DCH, Enhanced Dedicate Chan...
