FIELD: radio engineering, communication.
SUBSTANCE: invention particularly discloses a method which involves: configuring a subframe of a time division duplex (TDD) relay frame for a subframe of relay link (S201). Configuring the subframe of the TDD relay frame for the subframe of relay link involves: configuring a downlink (DL) subframe of the TDD relay frame for a DL subframe of relay link, and/or configuring the DL subframe of the TDD relay frame for an uplink (UL) subframe of relay link, and/or configuring a UL subframe of the TDD relay frame for the UL subframe of relay link; and performing relay transmission according to the subframe of relay link (S202). When data is transmitted, a subframe that can be used for relay link transmission is configured, data transmission performed by using relay link complies with inherent constraints of a TDD frame structure in the prior art. Coverage of the system using the TDD relay frame is therefore expanded.
EFFECT: high throughput owing to a relay node performing time division duplex relay transmission.
