Description

200822613 IX. Description of the invention: [Technical field of the invention] The present invention refers to a method for transmitting multiple links of a user terminal over a multi-input wireless communication system and its phase, especially A method of performing uplink transmission and a related device thereof correctly for a multi-input and multi-output client. Chuan

[Prior Art] Multi-input Multi-output (ΜΙΜΟ) communication technology refers to the simultaneous transmission and reception of wireless signals through multiple antennas, without increasing the bandwidth or total transmission power loss (Transmit Power Expenditure). Significantly increase the system's data throughput (Throughput) and transmission distance to effectively improve the spectrum efficiency and transmission rate of the wireless communication system, thereby improving communication quality. > In general, multi-input and multi-output communication technologies have the following modes of operation, including: 1. Spatial Multiplexing: At the transmitting end, the data stream is divided into multiple sub-data streams, each sub-stream Transmitted on the same frequency band through different transmit antennas, thus increasing channel capacity under high signal-to-noise ratio conditions. —TransmitDiversity: Or a variety of spaces, which are beneficial - use the multiple transmission channels provided by multiple antennas at the transmitting or receiving end to transmit the same information to enhance the transmission quality of the data. 6 200822613 2. Beamforming: A beam with directivity is generated by multiple antennas to concentrate energy in the direction of transmission, increase signal quality, and reduce interference with other users. The operation of the above-mentioned eve input communication technology is not exclusive, but can be applied to each other. On the other hand, 'next generation mobile communication systems, such as the Long Term Evolution (LTE) wireless communication system, are advanced high-speed wireless communication based on third-generation mobile communication systems such as the Global Mobile Telecommunications System. System, which uses high-speed downlink packet access technology (HighSpeedDownlinkPackage

Access ' HSDPA) and High Speed Up Toe Package Access 'HSUPA' are used to improve the efficiency of bandwidth usage and the processing efficiency of packet data to improve the transmission speed of the uplink and the downlink. Both the high-speed downlink packet access technology and the high-speed uplink packet access technology use Hybrid Automatic R Request (harq) to improve the retransmission speed and reduce the transmission delay. Hybrid automatic retransmission request technology is a technology that combines feed-forward error correction (Feed-forwaixlEnwCorreetiGn, FEC) and automatic retransmission request method, using the "multi-channel stop and wait" (M full lion d Stop and Wait) The algorithm 'that is, each channel can retransmit the packet or transmit the next packet according to the confirmation signal UCK/NAOC sent back by the receiving end. Long-term evolution of the wireless communication (four) system can achieve high rate 200822613, and large capacity on the limited Lai Wei. However, such a job requires a technology that has a high efficiency. Therefore, the conventional technology has been used in the multi-output communication technology guide _ into the scale communication system, using multiple antennas to achieve multiple transmissions and multiple receptions, without increasing the spectrum resources and antenna transmission power, can be doubled Improve channel capacity. Through multiple input and communication technologies, the transmission block (Transp()rtBk)ck), such as data or control messages, is processed by different hybrid automatic repeat request units (harq • entity), making hybrid automatic The number of resend request orders ^ may be multiplied (depending on the number of antennas). In other words, the per-hybrid automatic repeat request unit maintains all its transmission attributes (such as resource unit allocation, modulation, coding and transmission block size, retransmission time, etc.) - or different 'so that the corresponding hybrid The automatic resend request operation may be affected by the multiple input multiple output mode used. In another aspect, when the uplink transmission is implemented by multiple inputs and multiple outputs, the characteristics of the transmission area, the transmission resources, the system load, the transmission frequency or the importance are different. Ideally, the user should be able to _ Recording mode, in accordance with the resources allocated by the upper channel resource configuration message (Scheduling lnf_atk) n) (ie, the allowed value, Gram) mosquito transmission behavior. The uplink resource configuration message is output by the network to indicate the f source (allowed value) that can be used for the link transmission on the client side. The related definition and operation mode are known in the industry. Do not repeat them. Furthermore, relative to data transmission, the transmission of control signaling may require the use of different multi-input multi-output modes and resources to provide the information required by the system. However, in the prior art uplink multi-user multi-input (ON) application, 8 200822613 co-time non-contact can not use different multi-round multi-output mode, thus limiting users The operation of the end.
