Problems solved by technology

[0009] The purpose of the present invention is to provide a method for obtaining scheduling control information in high-speed packet access, so as to solve the system control problem caused by the long-term inability of users to obtain continuous scheduling in the prior art, and because the accompanying DPCH is used in the system, the It limits the real-time access of other users in the system, affects the number of users supported by the system and the service rate that can be supported, increases the complexity of the scheduling algorithm, and makes it easier to realize the high-speed downlink and uplink packet access features in the system. At the same time, the system is optimally controlled
[0010] Another object of the present invention is to provide a base station and a user terminal applying the method of the present invention to solve the problem of using the accompanying DPCH to carry scheduling control information in the prior art, and to make the characteristics of high-speed downlink and uplink packet access in the system easier accomplish

Embodiment Construction

[0072] The core of the present invention is aimed at the problem of obtaining scheduling control information through accompanying DPCH in HSDPA / HSUPA, and cancels the use of accompanying DPCH by adopting the method of obtaining scheduling control information under the sharing mechanism, thereby solving the control problem caused by discontinuous scheduling At the same time, solve the problems caused by adding DPCH, optimize the system and improve the performance.

[0073] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0074] In the system of the present invention, the uplink and downlink accompanying DPCH channels are not configured for each access user. When discontinuous data transmission occurs at each user terminal, the system starts the scheduling of users by setting certain conditions to obtain scheduling control informa...

Abstract

A method for acquiring scheduling control information in a high speed grouping interface is disclosed in the present invention, comprising steps: to obtain this time scheduling control information through processing the scheduling control information acquired by one time scheduling on the uplink and downlink channels in the system according to the scheduling user service kind, and sending this time scheduling control information by the uplink and downlink channels. A base station is also disclosed in the present invention, comprising a base station acquiring scheduling control information unit, and a user terminal, comprising the terminal acquiring scheduling control information unit. The present invention leads the user applying the HSDPA or HSUPA service to be able to acquire scheduling control information without DPCH companion, reduces effectively physical resource spending brought by companion DPCH, leads the HSDPA / HSUPA speciality to be able to realize.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for obtaining scheduling control information in high-speed packet access, a base station and a user terminal. Background technique [0002] In order to improve the downlink data transmission rate, the 3GPP (Third Generation Partnership Project) R5 version introduced HSDPA (High Speed ​​Downlink Packet Access) technology, and at the same time, in order to increase the uplink data transmission rate to support services such as games, 3GPP The HSUPA (High Speed ​​Uplink Packet Access) technology was introduced in the R7 version. [0003] In the 3G TDD (Third Generation Mobile Communication Time Division Duplex) system using HSDPA / HSUPA technology, the sharing mechanism based on IP network is mainly used, that is, multi-user sharing data channel and multi-user sharing scheduling control and feedback channel. In order to respond to the wireless environment in a...
