Relay method and equipment

The invention discloses a relay method and equipment. The relay method is applied to a half-duplex relay and comprises the following steps of: sending the same first symbol vector to relay equipment and receiving equipment in a first time interval; and sending a second symbol vector to the receiving equipment in a second time interval to ensure that the receiving equipment acquires the first symbol vector and the second symbol vector according to a third symbol vector received in the first time interval and a fourth symbol vector received in the second time interval, wherein the third symbol vector comprises the first symbol vector sent by the sending equipment, and the fourth symbol vector comprises the second symbol vector sent by the sending equipment and the first symbol vector forwarded by the relay equipment. Through the technical scheme, full rate transmission of the symbol vectors can be obtained in a half-duplex relay transmission system.
