Method for processing NDI in random access procedure and a method for transmitting and receiving a signal using the same
A method for a user equipment (UE) to receive a downlink signal, the method including receiving a first downlink control channel identified by a temporary cell identifier (Temporary C-RNTI) from a base station, the first downlink control channel including a first downlink assignment signal having a new data indicator (NDI) with a first value; receiving a second downlink control channel identified by a cell identifier (C-RNTI) from the base station, the second downlink control channel including a second downlink assignment signal having the NDI with a second value; and determining if the NDI has been toggled compared to the NDI previously received from the base station. Further, the UE ignores the NDI with the first value received through the first downlink control channel identified by the temporary cell identifier (Temporary C-RNTI). The method also includes receiving the downlink signal based on the determining.
