Embodiment 1

[0052] Image 6 It shows the flow chart of the MIMO user sending HS-SCCH information in this example. Such as Image 6 shown, including the following processes:

[0053] (61) When the Node B is for single-stream transmission, transmit according to the HS-SCCH (type 1) configuration channel type; when the Node B is for dual-stream transmission, transmit according to the HS-SCCH (type 2) configuration channel type; UE side Monitor all HS-SCCH channels;

[0054] (62) The UE demodulates the HS-SCCH channel;

[0055] (63) The MIMO user reads the corresponding channelization code set bit information;

[0056] (64) judge k start ≤k stop Whether it is established, if it is established, it is determined to be MIMO user single-stream transmission information, and execute (67), otherwise execute (65);

[0057] (65) judge k start = 16 and k stop = Whether 1 is established, if established, then execute (67), otherwise judge k start and k stop Whether it is MU-MIMO is used to ind...

Abstract

The invention discloses an implement method of a high-speed shared control channel under a multiple-input multiple output mode, comprising the steps: a high-speed shared control channel structure is expanded under a condition that the multiple-input multiple-output mode is a double-current multiple-input multiple-output mode, and a size index and a modulating mode of an auxiliary transmission block are indicated under the double-current multiple-input multiple-output mode by using an invalid state of a channelizing code set mark in a mark channel structure. By the technical scheme, the implement method can satisfy the requirement of double-current transmission under the multiple-input multiple-output mode, an HS-SCCH channel bit number has no need to be additionally increased; and the coding gain of the prior HS-SCCH can not be reduced.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a method for realizing a high-speed shared control channel in a multiple input multiple output (MIMO) mode. Background technique [0002] The MIMO technology is a hot research field in the field of mobile communication in recent years, and it is characterized in that both the wireless transmitter and the receiver introduce multiple antennas. Compared with the traditional single input single output (SISO) system, the MIMO system greatly improves the system capacity through space diversity technology or space multiplexing technology. [0003] Such as figure 1 As shown, in the non-MIMO mode, according to the 3GPP protocol TS25.222, the composition of the downlink high-speed shared control channel (High Speed ​​Shared control channel, HS-SCCH) channel is: 8-bit channelization code set identifier (CCS), 5-bit Time slot position information (TS), 1-bit modulation method (MF), 6...
