摘要:
A method by a user equipment is disclosed for decoding data from a network node in a telecommunications system. The method includes determining whether a discovery signal was received from the network node by detecting of another signal received from the network node, which may be a Primary Synchronization Signal (PSS) and/or a Secondary Synchronization Signal (SSS). Based on detecting that the another signal was received, the method includes determining whether a grant is present based on processing an Evolved Physical Downlink Control CHannel, ePDCCH. Based on determining that a grant is present, the method includes decoding a Physical Downlink Shared Channel, PDSCH, using the ePDCCH and the discovery signal.
