Description of the Invention: [Technical Field] The present invention relates to a method for performing transmission of multiple input and multiple output on a network side of a wireless communication system, and a related device thereof, and more particularly, a network transmission corresponding The information is sent to the client or the corresponding control flow is executed to correctly execute the method of multi-input multi-output over-key or downlink transmission and related devices. [Prior Art] Multi-i叩ut Multi-output (ΜΙΜΟ) communication technology refers to the synchronization of wireless signal transmissive antennas, which can increase the bandwidth or total transmission power loss (TransmitPowerExpenditure). The system greatly increases the system's throughput (ThlOUghput) and transmission distance to effectively improve the spectrum efficiency and transmission rate of the wireless communication system, thereby improving communication quality. In general, 'multiple input and multiple output communication technology has the following modes of operation, including: 1. Spatial Multiplexing · At the transmitting end, the data stream is divided into multiple sub-data streams by the knife brake, and each sub-data stream is transmitted through Different transmit antennas are transmitted on the same frequency band, thus increasing channel capacity under high signal-to-noise ratio conditions. Second, TransmitDiversity: or spatially diverse, it uses the multiple transmission channels provided by multiple antennas at the transmitting or receiving end to transmit the same resources 200836513 to enhance the transmission quality of data. Beamforming (Beamfonning): 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 above-mentioned multi-input and multi-output communication technologies operate in a way that is not exclusive, but can be applied to each other. On the other hand, a new generation of mobile communication systems, such as the Long Term Evolution (LTE) wireless communication system, is an advanced high-speed wireless communication built on third-generation mobile communication systems such as the Global Mobile Telecommunications System. The system uses the High Speed Downlink Package Access (HSDPA) and High Speed Uplink Package Access (HSUPA) to improve the bandwidth efficiency. The processing efficiency of the 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 Repeat Request (HARQ) to improve the retransmission speed and reduce the transmission delay. The hybrid automatic repeat request technology is a technology that combines feed-forward error correction (FEC) and automatic retransmission request methods, and uses a "multi-channel stop and wait" (Multi-channel Stop and Wait) algorithm, that is, each channel can decide whether to retransmit the packet or transmit the next packet according to the acknowledgement signal (ACK/NACK) sent back by the receiver. 200836513 Long-term evolution wireless Lai system can achieve high speed and large capacity in New Zealand. Such operations as Lions require techniques with extremely high spectral efficiency. Therefore, the prior art has multi-input multi-output communication technology to lead the long-term evolution wireless communication system to use multiple antennas to achieve multiple transmissions and multiple receptions, which can be multiplied without increasing the spectrum resources and antenna transmission power. Increase channel capacity. Through multi-input and multi-output communication technology, the transmission block (Transp〇rtB1〇d〇, 10 such as data or control messages, will be processed by different hybrid automatic repeat request unit (Harq e_y), so that hybrid automatic retransmission The number of requesting units may be multiplied (depending on the number of antennas). In other words, the per-hybrid automatic repeat request unit shall maintain 'all its transmission attributes (such as resource unit allocation, modulation, coding, and transmission block size, 'Retransmission time, etc.' is different or different, so that the corresponding hybrid automatic repeat request operation may be affected by the multiple input multiple output mode used. In addition, the currently known long term evolution wireless communication system architecture In the middle, the hybrid automatic retransmission of the uplink requires φ to operate synchronously (non-adaptive), while the non-synchronous (adaptive) operation mode remains to be studied. On the other hand, with multiple inputs and multiple outputs When implementing uplink transmission, with the characteristics of transmission block, transmission resources, system load, transmission frequency or importance, ideally, the user should be able to use different The multiple input multiple output mode determines the different transmission behavior according to the resource allocated by the uplink resource configuration information (Scheduling Information), wherein the uplink resource configuration information is determined by the network side. The output is used to indicate the amount of resources that can be used for the link transmission on the client side (allowing 8 200836513 to pass the value), and the phase n and the operation mode are well known, and will not be described here. To provide information that I need. However, in the prior art multi-user and multi-input multiple-round (UplinkMulti) applications, the ::= terminal cannot use different multi-input multi-round mode. : 限限_ [Summary] More than eight::==:r-input multi-input is used in one of the wireless communication systems to perform multi-transmission to the round, including in the network At least one hybrid
