Problems solved by technology

This means that according to the protocol, when the RNC sends the same number of CTFCs to the UE and the NodeB, if the RNC uses the same configuration data for the Node B and the UE, the number of CTFCs on the UE side will increase by 1. As a result, the number of CTFCs and the encoding length of the TFCI codewords are inconsistent, and there is no solution to this problem in the current protocol and prior art solutions

Embodiment Construction

[0039] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] After the RNC sends the CTFC parameter to the Node B and the UE, the Node B and the UE process the parameter according to the current 3GPP protocol, that is, the Node B and the UE process the parameter in different ways. In order to ensure that the TFCS stored in Node B and UE is the same, the CTFC parameters and order sent by RNC to Node B and UE must be different in the present invention, so as to adapt to the different processing methods of Node B and UE, that is to say, when RNC The CTFC sequence sent to the UE is {CTFC 1 , CTC 2 ,...,CTFC n}, the CTFC sequence sent by RNC to Node B is different, and RNC adds 1 CTFC before this CTFC sequence x , forming a new CTFC sequence {CTFC x , CTFC 1 , CTC 2 ,...,CTFC n}, where CTFC x will be overridden by the default configuration in Node B, CTFC 1 , CTC 2 ,...,CTFC n Exactl...

Abstract

The present invention discloses time division duplexing code division multiple access system transmission format combination parametric configuring method. It contains wireless network controller transmitting different calculating transmission format combination sequence to user terminal and node B, and configuring same transmission format combination indication word length, user terminal and nodeB forming transmission format combination set according to received calculating transmission format combination sequence and transmission format combination indication word length, said method avoiding TFCS data collocation incongruous status in current technology, adequate assurance Node Band UE stored TFCS quite correct and same, TFCI word length ensuring satisfying TFCS to encoding length requirement.

Description

technical field [0001] The present invention relates to the data transmission technology in the third generation mobile communication system, especially the Radio Network Controller (Radio Network Controller, RNC), Node B (NodeB) and User Equipment (User Equipment) in the Time Division Duplex Code Division Multiple Access communication system , a method for configuring the transport format combination parameter and the transport format combination indicator length in a consistent manner among UEs. Background technique [0002] Code Division Multiple Access (CDMA) is currently recognized as the mainstream technology of the third-generation mobile communication system, which includes two Frequency Division Duplex (FDD) technologies and a Time Division Duplex (Time Division Duplex) technology. Division Duplex, TDD) technology. [0003] In the 3GPP (3rd Generation Partnership Project) specification, the transport channel is used to carry data transmission services between the p...
