Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] The core idea of ​​the present invention is: for the control channel, use precoding and diversity technology, and use multiple antennas to repeatedly send system control information to ensure reliable transmission of the control channel; Data is distributed to multiple antennas for simultaneous transmission. The invention uses time division multiplexing to combine the control channel and the service channel, and improves the throughput rate of the system under the premise of ensuring the reliability of the channel, and improves the system performance.

[0030] Fig. 1 is a schematic diagram of the composition structure of the channel multiplexing device in the LTE system of the present invention. As shown in Fig. 1, the channel multiplexing transmission device of the present invention includes a precoding unit 10, a control channel configuration unit 11, a traf...

Abstract

The invention discloses a channel reuse method of the third generation mobile communication long-term evolution system. The invention, which relates to channel reuse technology, is put forward to solve the unclear channel control of the LTE system. The adopted technology scheme is as follow: the control channel is arranged in the anterior symbols of the sub frame, the traffic channel is arranged in the rest sub frame symbols; A diversity mode is adopted to control the channel to send system control information, and the reuse mode is adopted to send business data on the traffic channel. The invention also discloses a device to realize the method. Not only can the reliability of sending system control information be ensured, but also the transmission rate of the business data is higher. Arranging the control channel in the anterior symbols of the sub frame is beneficial to reduce the UE receiving delay.

Description

technical field [0001] The present invention relates to the third generation mobile communication (3G) Long Term Evolution (LTE, Long Term Evolution) system channel multiplexing technology, in particular to a method and device for multiplexing control channels and traffic channels in the 3G LTE system. Background technique [0002] In order to face the future and build sustainable competitiveness, the Third Generation Mobile Communications Global Standards Organization (3GPP) formally established the LTE research project in December 2004. The starting point of LTE is to ensure the competitiveness of 3GPP in the next ten years, and get comprehensive improvements in terms of performance, function and cost. Compared with 3GPP Release 6, the spectral efficiency of LTE downlink will be increased by 3 to 4 times, and the uplink will be increased by 2 to 3 times. In order to achieve the purpose of high-speed data transmission, the 3GPP organization decided to adopt the advanced an...
