1. A method for controlling a transmission of information in a wireless communication network between a radio access node and a relay node, the information being transmitted in a sequence of subframes, wherein a subframe comprises a control region and an information region containing the transmitted information, and a subframe corresponds to a transmission time interval, the method comprising:
allocating a downlink subframe for a downlink transmission of information from the radio access node to the relay node, wherein a downlink subframe for a downlink transmission is allocated only when a further subframe of the same transmission time interval for a transmission from the relay node to a user equipment is a subframe of a type that indicates to the user equipment that no data are received beyond the control region, and allocating, for an allocated downlink subframe, an uplink subframe for an uplink transmission of information from the relay node to the radio access node a certain number of transmission time intervals later,
wherein, when an uplink subframe is received from the relay node, corruption of the information contained in the received uplink subframe is checked,wherein when corruption is not detected in the uplink subframe, no acknowledgment of the received uplink subframe is transmitted, andwherein when corruption is detected in the uplink subframe, an uplink grant is transmitted to the relay node. |
