FIELD: radio engineering, communication.SUBSTANCE: invention relates to communication engineering and can be used in cellular communication systems. A relay node of a radio access network (RAN) is configured to communicate using backhaul subframes over a radio interface Un with a donor base station node and to communicate using access subframes over a radio interface Uu with a wireless terminal. Downlink backhaul subframes and downlink access subframes are transmitted over an air interface using the same frequency band, but the beginning of a selected downlink access subframe precedes the beginning of a next-in-time downlink backhaul subframe by a downlink timing advance (TA). The relay node receives downlink control information from the donor base station node and transmits downlink control information to the wireless terminal during the downlink backhaul subframe, e.g., during a time to which the downlink backhaul subframe has been allocated.EFFECT: high transmission channel throughput.22 cl, 17 dwg |
