Problems solved by technology

[0020] 5. Two-way signal transmission path delay between NodeB and UE
For some current NodeB implementation architectures, due to the limited processing capacity, it is impossible to realize the overall scheduling of users and meet the closed-loop timeliness requirements. This is very detrimental to the timeliness and fairness of MAC-E scheduling, and the scheduling performance of MAC-E will be affected

Embodiment Construction

[0036]Under the premise of not affecting the reliability of E-RGCH transmission, the present invention sets the E-RGCH air interface transmission duration and gives the NodeB appropriate processing time to realize the overall MAC-E scheduling.

[0037] In the current HSUPA 10ms TTI application scenario, and in the MAC-E scheduling and application closed-loop process, the most stringent requirement on the NodeB processing time is the formation and transmission of the RG that belongs to the serving E-DCH RLS. In this case, it is required The air interface transmission duration of E-RGCH information is 4 short frames of 2ms with repeated information, totaling 8ms.

[0038] As shown in Table 1, in the present invention, according to different NodeB levels, the RNC sets different times of repetition of the 2ms short frame.

[0039] NodeB processing level Repeat 2ms short frame times highest 4 high 3 in 2 low 1

[0040] Table 1. The relationship be...

Abstract

The invention relates to a communication method between mobile terminal and base station, which comprises: the base station reports the processing level information to the base station controller; the controllers based on said processing level, inquires the repeated short frame times of strengthen ascending special transmission channel of strengthen ascending special transmission channel; the controller distributes the repeated short frame times via the repeated short frame times to the base station and mobile terminal; the base station based on the repeated short frame times calculates out the processing time; the mobile terminal based on the strengthen ascending special transmission channel relative priority channel repeated short frame times, receives and processes the strengthen ascending special transmission channel relative priority channel information; therefore, the invention can distribute right processing time to the base station, via setting E-RGCH idle transmission kept time, without affecting the reliability of E-RGCH, to realize the adjustment on MAC-E, to confirm the property of MAC-E distribution.

Description

Technical field [0001] The invention relates to a communication method between a mobile terminal and a base station, in particular to a communication method in which the mobile terminal sends different short frame times according to the level of the base station. Background technique [0002] With the development of the times, communication technology has also developed, and the third-generation wireless communication (3G) has also entered the application stage. [0003] High Speed ​​Downlink Packet Access (HSUPA) is an important new feature in the WCDMA (Wideband Code Division Multiple Access) standard in 3G. Compared with the original R99 feature, it has the following New features: [0004] 1. The uplink data inner loop confirmation mechanism between the mobile terminal (UE) and the WCDMA base station (NodeB). UE sends uplink E-DCH enhanced (uplink) dedicated transport channel (Enhanced Dedicated Transport Channel, E-DCH) data, NodeB receives the data block and confirms it, and...
