Description of the invention: [Technical field of the invention] The present invention relates to a method for transmitting a multi-input and multi-output of a multi-input and multi-output user terminal of a wireless communication system, and a related device thereof, especially one that is correct ^ Ding input multiple rounds of the client to perform the method of multi-input and multi-output transmission and its related = set. , sentence clothing • [previous technology] 'Multi-i叩ut Multi-output (ΜΙΜΟ) communication technology - 疋 然 然 汛 透过 透过 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重In the case of the total transmission power loss (Transmitpower Expenditure), the data throughput (Throughput) and transmission distance of the system are greatly increased, so as to effectively improve the spectrum efficiency and transmission rate of the wireless communication system, thereby improving the 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, 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. 1. Transmit Diversity · or space diversity 'The same transmission is transmitted by multiple transmission channels provided by multiple antennas at the transmitting or receiving end to enhance the transmission quality of the data. - Beam into S (Beamf_ing): A plurality of antennas are used to generate a direction of directivity of the wire, which increases the quality of the off-chip and reduces interference with other users. The operation of the above-mentioned input and output multi-output communication technology is not exclusive, but can be applied to each other. Another aspect of the new generation of mobile communication systems, such as the Long Term Evolution (LongTerm Εν-, LTE) wireless communication system, is an advanced high-speed wireless communication system built on the third generation mobile communication system (such as the ^ ball mobile telecommunications system). It uses high-speed downlink packet access technology (HighSpeedD_丨inkpackage

Both the high-speed secret packet access technology and the high-speed uplink packet access technology use Hybrid Automatic Repeat Request (HARQ) to increase the speed of retransmission and reduce transmission delay. The hybrid automatic repeat request technology is a technology that combines a feed-forward error correction (FEC) and an automatic repeat request method, and uses a "multi-channel stop and wait" (Muki_channel Stop and Wait). The algorithm, that is, each channel can decide whether to retransmit the packet or transmit the next packet according to the acknowledgement nickname (ACK/NACK) sent back by the receiving end. 200822612 Long-term evolution wireless reliance can be achieved in the __transfer, achieving high speed and large valley m. Therefore, the Newcomer multi-output communication technology guides the long-term evolution of the wireless communication system. Multiple antennas can achieve multiple transmissions and multiple transmissions, and the channel capacity can be doubled without increasing the resources and antenna power. Through multi-input multi-output communication technology, the transmission block (τ job p(10)B off), such as tribute or control message, will be processed by different hybrid automatic repeat request unit (harq ==, so that hybrid automatic retransmission The number of financial units can be increased (as determined). In other words, the 'per-hybrid automatic retransmission request unit should maintain the attributes of the casting (such as resource allocation, modulation, coding and transmission block size, • Intermittent or different 'make the corresponding hybrid automatic repeat request operation (4) the multi-input multi-output mode used. In addition, in the current == period _ wireless communication system bribe, the mix of the uplink Automatic retransmission, please use synchronous (non-adaptive), non-synchronous (adaptive) operation is still to be studied. In other words, when multiple transmissions and multiple outputs are used to achieve uplink transmission With the characteristics of transmission area acquisition, transmission resources and system load, transmission frequency or importance, on the j, the user should be able to use different multi-input multiple output modes according to the upper key (Scheduling lnf0rmati0n) ( ,p^# changed from net (10)) mosquito Behavior, in which the uplink dragon, the configuration message system, and the rounding out, are used to indicate the amount of resources that can be used for the link transmission on the client side (allowing the 200822612 special value). In this case, the transmission of control signaling for the poor material transmission may need to be used in the round-robin mode, to _ tear the message. Fine, she: multi-user and multi-input multiple rounds (Up丨ink) Leak-forward MIMo) It should be expected that different users can not use different multi-input and multi-output modes, and the user's operation is limited.
