A transmission wireless communication system, comprising: a transmitting end comprising a transmission module having at least two antenna units, wherein the transmission module transmits M narrow wave beams of different spatial directions according to the requirement of quality of service (QoS) and switches a transmission mode according to a pre-set switching rule, and a set of the spatial directions of the M narrow wave beams forms a transmission mode; and a receiving end comprising a receiving module having at least two antenna units, wherein the receiving module receives N wave beams according to the QoS, and a transmission channel is formed between the M narrow wave beams of the transmitting end and the N wave beams of the receiving end. The receiving end calculates the quality of the transmission channel under different transmission modes, searches for the transmission mode meeting the requirement of the QoS, feeds back the transmission mode to the transmitting end or feeds back the transmission mode with the optimum channel quality to the transmitting end if the transmission mode meeting the requirement of the QoS cannot be found after the transmission channel quality corresponding to all transmission modes is traversed, wherein both M and N are an integer greater than or equal to 1. |
