摘要： 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.

摘要： A wireless communication user terminal obtains uplink access configuration information on a physical downlink control channel (PDCCH) addressed to a plurality of user terminals by processing the PDCCH based on a first system information received from a base station on a physical broadcast channel (PBCH) and based on synchronization information. The terminal sends a signature waveform based on the uplink access configuration information, prior to receiving system information in addition to the first system information, whereby the signature waveform enables the base station to transition from a relatively low power operating mode to a relatively high power operating mode.
