FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a wireless communication system which uses relay. The invention particularly discloses a method which includes: configuring a subframe of a time division duplex (TDD) for a subframe of relay link (S201), where the configuring the subframe of the TDD relay frame for the subframe of the relay link includes: 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 and coverage of the system using the TDD relay frame.
EFFECT: high throughput by designing a relay system when performing data transmission in accordance with a TDD relay frame structure.
