Embodiment Construction

[0022] figure 2 It is a schematic representation of the steps of the method for generating the HSDPA system user identifier H-RNTI of the present invention.

[0023] In HSDPA, the user identity H-RNTI is transmitted through a specified channel. In order to ensure that the user identity H-RNTI of any two different HSDPA users in the same cell is significantly different in the case of binary representation, such as figure 2 As shown, generate the user identification H-RNTI with the following steps: (1) step 101 of sequentially generating the temporary user identification H-RNTI-TEMP; (2) adopting error correction coding to generate the temporary user identification H-RNTI-TEMP Step 102 of encoding the TEMP to generate the user identity H-RNTI.

[0024] The principle of using the above steps to generate the user identification H-RNTI is as follows: in the HSDPA system, in order to ensure that the user identification H-RNTI of any two different HSDPA users in the same cell is s...

Abstract

The method comprises: 1) sequentially generating the temporary user ID 'H-RNTI-TEMP'; 2) using the forward error correction coding to encode the temporary subscriber ID 'H-RNTI-TEMP' in order to generate the user ID 'H-RNTI'. The invention can avoid the error receiving of HS-SCCH in the HSDPA system.

Description

technical field [0001] The present invention relates to mobile communication system technology, in particular to the technology of HSDPA (High Speed ​​Downlink Package Access, High Speed ​​Downlink Packet Access) system in UMTS (Universal Mobile Communication System) to calculate and distribute user identification H-RNTI. Background technique [0002] The UMTS (Universal Mobile Telecommunications System) system is a third-generation mobile communication system using WCDMA as a wireless technology. WCDMA can use UTRA (Universal Terrestrial Radio Access) FDD (Frequency Division Duplex) and UTRA TDD (Time Division Duplex) two duplex modes, and its main specification versions include Release 99, Release 4, Release 5 and Release 6, etc. Among them, the Release 99 and Release 4 specifications can support data transmission rates ranging from 384Kbps to 2Mbps. In order to enhance the throughput of downlink non-real-time packet services and improve the spectrum efficiency of the wir...
