Method and Arrangement in a Radio-Access Network

A network node, comprising a transceiver adapted to transmit control information in a subframe from the network node to an intermediate node in a radio-access network, wherein the control information is comprised in a time-frequency region transmitted after a control region that is transmitted in a beginning of the subframe, the network node wherein:

• the transceiver is further adapted to transmit first control information in a first part of the time-frequency region and second control information in a second part of the time-frequency region, wherein the time-frequency region is divided so that the second part is located later in the subframe than the first part and wherein said second control information is less time-critical than said first control information.

An intermediate node adapted to receive control information in a subframe from a network node in a radio-access network, wherein the control information is comprised in a time-frequency region located after a control region that is located in a beginning of the subframe, wherein the intermediate node comprises:

• a transceiver adapted to receive first control information in a first part of the time-frequency region and to receive second control information in a second part of the time-frequency region, the transceiver further adapted to, when said first control information indicates that the subframe comprises data payload to the intermediate node, receive the data payload;
• and
• a processor connected to said transceiver and adapted to control transmission and reception by said transceiver, the processor further adapted to decode the first control information, wherein the processor is adapted to start decoding the first control information at or after an end of the first part of the time-frequency region, the processor further adapted to, when said first control information indicates data payload to the intermediate node in the subframe, decode the data payload.
