Problems solved by technology

However, the TD-SCDMA system in the current 3GPP agreement is a single-carrier system, that is, one cell corresponds to one carrier frequency, and the spectrum width of a single carrier frequency is 1.6M. Since TD-SCDMA adopts a relatively narrow-band TDD method, the theoretical The peak rate can reach 2.8Mbps, and the downlink peak rate that can be provided on a single carrier is relatively low, which cannot well meet the needs of operators for future high-speed packet data services

Embodiment Construction

[0028] Such as figure 1 As shown, it is a schematic flow diagram of a method for implementing multi-carrier high-speed downlink packet access in a time division synchronous code division multiple access system according to an embodiment of the present invention, including:

[0029] A multi-carrier cell or a single-carrier multi-cell system is established by the network side. In the multi-carrier cell or the single-carrier multi-cell system, the resources of multiple carriers are managed and allocated as a whole (step 101);

[0030] Configure HSPDA-related resources on at least one of the multiple carriers in a multi-carrier cell or a single-carrier multi-cell system, including HS-PDSCH, HS-SCCH, and HS-SICH physical channel resources. Among them, one HS-SCCH physical channel resource The channel and an HS-SICH physical channel on the same carrier are fixedly configured as a pair, and a MAC-hs processing entity is created to manage these resources (step 102);

Abstract

A method for realizing multicarrier high speed down link packet switching ¿C in of TD ¿C SCDMA system includes setting up a multicarrier cell at network side, configuring HS ¿C PDSCH as well as HS ¿C SCCH and HS ¿C SICH resource on one or multiple carrier, distributing one or multiple carrier with HS ¿C PDSCH resource as well as related one pair or multiple pair of H ¿C SCCH and HS ¿C SICH to user terminal, using HS ¿C PDSCH on one or multiple carrier to bear service data as well as using one related pair of HS ¿C SCCH and HS ¿C SICH to bear control information and feedback information when service data transmission is carrier out.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for realizing multi-carrier high-speed downlink packet access in a Time Division Synchronization Code Division Multiple Access (TD-SCDMA) system. Background technique [0002] An important feature of the third-generation mobile communication system is the unbalanced traffic volume of the uplink and downlink, and the traffic volume of the downlink will generally be greater than that of the uplink. In response to this requirement, 3GPP (3rd Generation Partnership Project, third-generation cooperation scheme) introduced the HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access) feature into the 3G specification. [0003] In the HSDPA feature, by introducing AMC (Adaptive Modulation and Coding, adaptive coding and modulation), HARQ (Hybrid Automatic Retransmission Request, hybrid automatic retransmission request) technology and related technologies...
