Embodiment Construction

[0031] The core idea and various preferred embodiments of the present invention will be further described and illustrated in detail below with reference to the accompanying drawings.

[0032] The present invention provides a method for dynamic scheduling of carrier resources in a TD-SCDMA multi-carrier HSDPA system. The radio link update process provides relevant carrier frequency indication information, and requires the RNC to reconfigure the radio link, so as to reconfigure the UE to an appropriate carrier frequency.

[0033] Fig. 1 is the described step flowchart of the inventive method, as shown in Fig. 1, this method comprises following two steps:

[0034]Step 1: When the high-speed shared resource changes, the NodeB sends a radio link parameter update indication message to the RNC to which it belongs, triggering the radio link parameter update process, wherein the radio link parameter update indication message contains information for indicating whether the RNC An infor...

Abstract

The utility model discloses a dynamic dispatch method for carrier wave resource used in a multi-carrier HSDPA system, which is characterized in the following steps that: when the high-speed shared resource changes, the wireless link circuit parameters update indication information is sent form a NodeB to the affiliated RNC to trigger the wireless link circuit parameters update process; wherein, the wireless link circuit parameters update indication information comprises an information unit, which is used for indicating the RNC whether to switch the carrier frequency currently carrying the high-speed shared communication channel in the UE to the information unit of the new frequency point; the RNC configures the carrier frequency carrying the high-speed shared communication channel in the UE according to the received indication in the information unit comprised in the wireless link circuit parameters update indication information. The utility model has the advantages that the free port resource is effectively utilized; the system capacity is increased, and the multi-carrier HSDPA technology and system is optimized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for dynamically scheduling carrier resources in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) multi-carrier HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) 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 is generally greater than that of the uplink. In response to this requirement, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) introduced a high-speed downlink packet access feature into the specification. At the same time, in the HSDPA feature, by introducing AMC (Adaptive Modulation and Coding, adaptive coding and modulation), HARQ (Hybrid Automatic Retransmission Request, hybrid automatic retransmissi...
