Problems solved by technology

[0008] The purpose of the present invention is to provide a method and device for supporting dual-stream transmission on an uplink high-speed shared information channel, so as to overcome the disadvantage of the HSDPA system that the HS-SICH channel cannot support dual-stream transmission in the prior art, and enable the HS-SICH channel to support dual-stream transmission The HSDPA system improves the data transmission rate and capacity of the TD-SCDMA system

Embodiment Construction

[0113] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0114] In order to understand the overall flow of the technical solution of the present invention more clearly, a brief introduction to the process of HSDPA is firstly made.

[0115] A brief description of the HSDPA process is as follows:

[0116] The base station Node B first notifies the UE of the corresponding HS-DSCH information through the HS-SCCH, including user identification, HS-PDSCH code channel resources, and modulation methods. Then, after a predetermined time interval, data is sent on the HS-DSCH. The UE monitors the HS-SCCH, and judges whether the time information belongs to the UE by identifying the user equipment identity information (UEID information). If so, according to the information carried by the HS-SCCH, the shared ...

Abstract

The invention discloses a method for supporting double-stream transmission of an uplink high-speed shared control channel, which comprises the following steps: A) HS-SICH channel control information which supports single-current transmission and double-stream transmission respectively is set; B) UE encodes the HS-SICH channel control information and transmits the HS-SICH channel control information to Node B; C) the Node B correspondingly decodes encoded control information on the HS-SICH; and D) the Node B determines whether to retransmit data and determines the transmission format of next data transmission according to decoded HS-SICH control information. Moreover, the invention also discloses a method for supporting double-stream transmission of a base station and the base station. Themethod can make the HS-SICH channel in a TDD system support double data stream transmission on the HS-SICH, so as to be capable of improving the data transmission efficiency and the data throughout of the TDD system.

Description

technical field [0001] The present invention relates to high speed downlink packet access (High Speed ​​Downlink Packet Access, HSDPA) technology in the technical field of mobile communication, especially relates to a kind of uplink high speed shared information channel (Shared Information Channel for HS-DSCH, HS-SICH) A method for performing dual data stream transmission on a downlink shared channel (High Speed ​​Downlink Shared Channel, HS-DSCH), a method for realizing a base station supporting dual stream transmission, and a base station. Background technique [0002] In the third-generation mobile communication system, with the expansion of data service types, the data traffic between the uplink and the downlink is asymmetrical, and the traffic volume of the downlink is generally greater than that of the uplink. Therefore, in order to To meet the user's needs for the transmission of uplink and downlink data services, the 3rd Generation Partnership Project (3rdGeneration ...
