Abstract:
A communication system is provided wherein a user equipment (UE) receives control information from a wireless network. The UE monitors control channel candidates using common reference signals (CRS) and monitors enhanced control channel candidates using demodulation reference signals (DMRS) when the UE is configured in a first transmission mode, such as transmission mode 9, for receiving a downlink shared traffic channel based on DMRS. The UE monitors control channel candidates only using CRS when the UE is configured in a second transmission mode, such as any of transmission modes 1-6, for receiving a downlink shared traffic channel based on CRS. The UE then receives downlink control information (DCI) in a subframe in one of the monitored control channel candidates or enhanced control channel candidates in the subframe.
