Channel configuration and allocation method applicable to multi-carrier high-speed downlink packet access

Abstract

The present invention provides a channel configuration and allocation method suitable for multi-carrier high-speed downlink packet access. A radio network controller configures multi-carrier high-speed downlink packet access resources in a multi-carrier cell, including high-speed physical downlink shared channel resources and high-speed Shared control channel and high-speed shared information channel pair resources. These resources are managed and allocated by Node B. The radio network controller allocates accompanying dedicated physical channels according to the recorded initial configuration information and initial allocation information of each carrier, and sends the configuration information to Node B, and Node B re-allocates high-speed physical downlink shared channel carrier resources, and associated High-speed shared control channel and high-speed shared information channel pair resources. The invention realizes the channel configuration and allocation of the high-speed downlink packet access technology in the multi-carrier environment.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a multi-carrier High Speed ​​Downlink Packet Access (HSDPA) system in a Time Division Synchronization Code Division Multiple Access (TD-SCDMA) system. ) technology implementation method. 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) ...

AI Technical Summary

Problems solved by technology

However, compared with the single-carrier HSPDA technology of the TD-SCDMA system in the existing 3GPP agreement, because in the TD-SCDMA multi-carrier HSDPA technology, a UE can be allocated physical channel resources on different carriers, resulting in multi-carrier HSDPA The HS-PDSCH physical channel, HS-SCCH and HS-SICH physical channel pair, and the configuration and allocation method of the uplink and downlink accompanying dedicated physical channels in the technology cannot follow the allocation method in the case of single carrier. Therefore, it is necessary to provide a A channel configuration and allocation method suitable for multi-carrier high-speed downlink packet access technology
