Embodiment Construction

[0025] In the current 3GPP Release 5 specification, HSDPA adopts a single-carrier transmission mode, that is, users receive service channel data on one carrier. Due to the limitation of signal bandwidth, the peak rate of data sent by HSDPA technology is affected to a certain extent. Combining with multi-carrier technology can further improve the data transmission rate of HSDPA technology.

[0026] In order for a multi-carrier cell to simultaneously provide services for user terminals with different receiving carrier capabilities, a certain mechanism should be provided so that the radio access network can allocate used carriers for user terminals according to their simultaneous receiving carrier capabilities.

[0027] In the TD-SCDMA (Time Division Synchronous Code Division Multipie Access) system, taking the user terminal to start a data transmission process as an example, the process from starting the connection to allocating resources is as follows:

Abstract

A working method of user terminal for high-speed downlink packet access service in multicarrier cell includes informing number of carrier being able to be received at the same time by it to radio access network in space interface message by user terminal, distributing carrier resource to said user terminal by radio access network according to number of carrier being able to be received at the same time by user terminal and transmitting data on carrier distributed from radio access network by user terminal.

Description

technical field [0001] The present invention relates to HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access service) of a wireless communication system, in particular to a working method of an HSDPA terminal in a multi-carrier cell. Background technique [0002] In order to support high-speed downlink data services, currently in the 3GPP (3rd Generation Partnership Project, Third Generation Partnership Organization) Release 5 specification, a high-speed downlink packet access service (HSDPA) is proposed, and all users share all code channel resources. Through adaptive coding and modulation (AMC) and hybrid request retransmission (HARQ) technology, a higher rate is allocated to user terminals with good channel environment, and a lower rate is allocated to user terminals with poor channel environment. [0003] Among them, the transmission channel used to carry high-level data is the High-speed Downlink Shared Channel (HS-DSCH), and the data of the HS-...
