    Abstract: Technology for downlink (DL) grant validation is disclosed. One method can include a wireless device receiving from a node a downlink grant masked with a cell radio network temporary identifier (C-RNTI) for a resource allocation (RA) including an enhanced physical downlink control channel (ePDCCH) physical resource block (PRB) carrying the downlink grant. The wireless device can validate a downlink control information (DCI) format of the downlink grant. The at least two UERS ports can be used to transmit two CCEs. The wireless device can determine that the downlink grant is received with a non-matching cyclic redundancy check (CRC) when the DCI format is not validated.
