Device and system for implementing multi-carrier high speed downlink packet access service

摘要

The invention discloses a device and a system for implementing a multi-carrier high speed downlink packet access service, thereby accomplishing multi-carrier high speed downlink packet access service transmission by means of multi-carrier high speed downlink packet processing devices provided in a base station and a user equipment in the system and managing high speed downlink packets corresponding to the carriers separately by means of hybrid automatic repeat request modules corresponding to the carriers. The invention further discloses a method for implementing a multi-carrier high speed downlink packet access service, thereby allocating a separate transmitting hybrid automatic repeat request process and corresponding receiving hybrid automatic repeat request process for each carrier to accomplish transmission and receiving of high speed downlink packet access data. With the invention, the downlink data transmission rate in a radio mobile communication system supporting multiple carriers can be improved.

主权项

1. A base station for implementing a multi-carrier high speed downlink packet access service, which accomplishes multi-carrier high speed downlink packet access service transmission by means of a network-side multi-carrier high speed downlink packet processing device in the base station; the base station comprising a processor and a memory, the memory storing instructions for causing the processor to implement the network-side multi-carrier high speed downlink packet processing device; the network-side multi-carrier high speed downlink packet processing device comprising a flow control module and a scheduling and priority handling module; wherein, the network-side multi-carrier high speed downlink packet processing device further comprises:
a plurality of network-side hybrid automatic repeat request modules and a plurality of transmission format and resource combination selection modules corresponding to carriers in a cell, wherein one network-side hybrid automatic repeat request module corresponds to one carrier; and each of the plurality of network-side hybrid automatic repeat request modules is coupled to the scheduling and priority handling module, and is designed to manage a hybrid automatic repeat request process for a corresponding carrier; and each one of the plurality of transmission format and resource combination selection modules is coupled to one hybrid automatic repeat request module which only corresponds to the transmission format and resource combination selection module, respectively, and is designed to select an appropriate transmission format and channel resource for data transmitted on a high speed downlink shared channel for a corresponding carrier, and wherein the instructions include instructions for causing the processor to provide the plurality of network-side hybrid automatic repeat request modules, the plurality of transmission format and resource combination selection modules, and the scheduling and priority handling module.
