Method for transmitting scheduling information of enhanced dedication channel and system thereof

Abstract

The present invention relates to a mobile communication technology, and discloses a transmitting method and system which are used for enhancing scheduling information in private channel and are capable of making a base station node execute grouping scheduling on E-DCH according to the latest SI report. In this invention, the RSN transmitted by the E-DPCCH is employed to determine that whether the received data from the base station node is transmitted by the first time or not, and if the result is yes, the base station node records arriving time of the data transmitted by the first time through saving connection-frame signals and sub-frame signals which correspond to the TTI of the data. When receiving the data containing the SI, the base station node determines that whether the arriving time of the data transmitted by the first time is posterior to the memorized receiving time the latest SI, and if the result is yes, the scheduling is executed with basis of the SI in the data and updates the memorized receiving time the latest SI with the arriving time of the data transmitted by the first time; and if the result is not, the SI in the data is ignored.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to the transmission of scheduling information in enhanced dedicated channels. Background technique [0002] UMTS (Universal Mobile Telecommunication System, Universal Mobile Telecommunication System) is one of the main third generation mobile communication (The Third Generation, "3G" for short) systems in the world at present. The UMTS system consists of three parts, namely the core network (Core Network, referred to as "CN"), Universal Mobile Telecommunications System Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, referred to as "UTRAN") and user equipment (User Equipment, referred to as " UE") composition. The interface between CN and UTRAN is defined as Iu interface, and the interface between UTRAN and UE is defined as Uu interface. [0003] The earliest protocol version of UMTS is R99. In this version, the bearing of uplink and downlink services is b...

Problems solved by technology

[0022] In practical application, the above scheme has the following problems: the base station node may not be able to obtain the latest SI report, thus affecting the performance of E-DCH uplink packet scheduling

Moreover, since the SI transmission has a very high priority, even the HARQ process whose service authorization parameter is a special value "Zero_Grant" and the HARQ process that is in an inactive state are allowed to transmit SI. Therefore, it is not difficult to find that in a certain During the HARQ retransmission of an SI report, it is very likely that the user terminal needs to send a new SI to the base station node

[0025] As shown in Figure 4, since the HARQ process except the old SI report retransmission, other HARQ processes may transmit a new SI report, and before the retransmission of the old SI report is completed, if the new SI report has been is successfully received by the base station node, then when the old SI report is successfully transmitted, the new SI report will be overwritten, resulting in the base station node not obtaining the latest SI report, which greatly reduces the uplink packet scheduling. performance
