RADIO COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To effectively utilize a time/frequency slot and increase in throughput of a system.SOLUTION: There is provided a multihop radio communication method. The method comprises: a first transmission process in which a base station 2 transmits a first signal to a first hop receiver 5; a first reception process in which a coexistence transmitter 4 receives the first signal; a first decoding process in which the first signal is decoded by using vector precoding based on channel information between the coexistence transmitter 4 and the first hop receiver 5; a precoding process in which the precoding of the first signal is performed; a first relay process in which the decoded and precoded first signal is relayed from the coexistence transmitter 4 to the first hop receiver 5; and a second transmission process in which a second signal from the coexistence transmitter 4 to the first hop receiver 5 is transmitted in a time zone which is the same as or different from that of the first relay process according to a status of a channel.
