Claim:
1. A method for downlink (DL) grant validation, comprising: receiving from a node a downlink grant that is semi-persistent scheduling (SPS) activate 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 in a subframe; validating a downlink control information (DCI) format of the downlink grant; treating the ePDCCH PRBs as PDSCH PRBs upon receiving the SPS activate downlink grant in the subframe containing the ePDCCH PRBs; performing a physical downlink shared channel (PDSCH) rate matching to the ePDDCH PRBs containing the SPS activate downlink grant; and determining that the downlink grant is received with a non-matching cyclic redundancy check (CRC) when the DCI format is not validated.
