TRANSMITTING AND RECEIVING NODES AND METHODS THEREIN FOR CONTROL CHANNEL TRANSMISSIONS IN A RADIO COMMUNICATIONS NETWORK

摘要

Embodiments herein relate to a transmitting node and method therein for transmitting channel information in subframes to a receiving node. Each subframe comprises a number of control channel elements and a set of control channel candidates. The transmitting node transmits control channel information in a subframe when a start control channel element index of a control channel candidate is smaller than or equal to the number of available control channel elements in a predefined subframe, and refrains from transmitting control channel information when the start control channel element index of the control channel candidate is larger than the number of available control channel elements in the predefined subframe. The embodiments also relate to a receiving node and method therein.
