FIELD: radio engineering, communication.
SUBSTANCE: invention relates to wireless communication engineering and can be used to transmit and receive control information in a radio access network. A network node comprises a transceiver adapted to transmit control information in a subframe (310) from a network node to an intermediate node (103) in a radio access network (120), wherein the control information is contained in a frequency-time domain (305), transmitted after the control domain (200), which is transmitted at the beginning of the subframe (310), wherein the control domain (200) is used for controlling signalling to user equipment (105), and the frequency-time domain (305) is used to transmit control channels given for a relay operation. The transceiver is further adapted to transmit first control information in a first portion (300) of the frequency-time domain (305) and second control information in a second portion (302) of the frequency-time domain (305), wherein the frequency-time domain (305) is divided such that the second portion (302) is situated after the first portion (300) in the subframe (310), and wherein said second control information is less critical on time than said first control information, wherein said first control information is associated with downlink information, and said second control information is associated with uplink information. The intermediate node of the radio access network is intended to receive control information from the network node.
EFFECT: higher efficiency of using frequency-time resources in a subframe.
