Embodiment Construction

[0038] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0039] In order to support the TD-SCDMA, TimeDivision-Synchronous Code Division Multiple Access (TD-SCDMA, TimeDivision-Synchronous Code Division Multiple Access) system, the present invention introduces SU-MIMO and MU-MIMO into the downlink HS-SCCH transmission, and needs to expand the HS-SCCH frame structure . The extended HS-SCCH still uses two downlink code channels with a spreading factor of 16, and still multiplexes the 4-bit synchronous power control information of SS and TPC.

[0040] In non-MIMO mode, HS-SCCH remains figure 1 The frame structure shown remains unchanged, and the present invention will figure 1 The frame structure shown is labeled TYPE1. In MIMO mode, the HS-SCCH frame structure is marked as TYPE2, which is divided into three different types:

[0041] TYPE2-A, representing the HS-SCCH fram...

Abstract

The invention discloses an information transmission method of a high-speed shared control channel (HS-SCCH), which comprises the following steps of: determining the transmission mode of a current scheduling user on a high-speed physical downlink shared channel (HS-PDSCH) by a base station according to a scheduling algorithm and determination rules; searching an HS-SCCH frame structure corresponding to the determined transmission mode in preset HS-SCCH frame structures corresponding to various transmission modes; and sending the information of HS-SCCH to the scheduling user according to the searched HS-SCCH frame structure. The invention also discloses an information transmission system which can realize single-current and double-current transmission based on an extended HS-SCCH frame structure in a multi-input multi-output (MIMO) mode.

Description

technical field [0001] The invention relates to an information transmission technology in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, in particular to an information transmission method and system based on high-speed shared control channel (HS-SCCH) frame structure extension. Background technique [0002] Single User Multiple Input Multiple Output (SU-MIMO, Simple User Multiple Input Multiple Output) technology is a popular technology in the field of mobile communication in recent years, and its wireless transmitter and receiver both introduce multiple antennas. Compared with the traditional Single Input Single Output (SISO, Simple Input Simple Output) system, the SU-MIMO system obtains a great increase in system capacity through space diversity technology or space multiplexing technology. Multiple User Multiple Input Multiple Output (MU-MIMO, Multiple User Multiple Input Multiple Output) technology is to use the space division between differ...
