A method in a user equipment for receiving control information transmitted in accordance with 3GPP LTE Release 11, the method comprising: monitoring Physical Downlink Control Channel (PDCCH) candidates in a subframe using common reference signals and monitoring Enhanced Physical Downlink Control Channel (EPDCCH) candidates in the subframe using demodulation reference signals (DMRS) when the UE is configured in a first transmission mode for receiving a Physical Downlink Shared Channel (PDSCH) based on DMRS; monitoring a set of PDCCH candidates in the subframe only using CRS when the UE is configured in a second transmission mode for receiving a Physical Downlink Shared Channel (PDSCH) based on CRS, wherein the set of PDCCH candidates is determined based on whether both PDCCH candidates and EPDCCH candidates are monitored by the UE in the subframe or, only PDCCH candidates are monitored by the UE in the subframe; and receiving downlink control information in the subframe in a PDCCH candidate of the monitored PDCCH candidates or in an EPDCCH candidate of the monitored EPDCCH candidates, wherein monitoring a control channel candidate comprises attempting to decode the control channel candidate using a reference signal for channel estimation purposes, wherein the UE receives an indication of a set of DCI formats for which the PDCCH candidates are monitored and a set of DCI formats for which the EPDCCH candidates are monitored, and wherein the set of DCI formats for which the PDCCH candidates are monitored and aggregation levels at which the PDCCH candidates are monitored depend on whether the UE is monitoring only the PDCCH or monitoring both the PDCCH and the EPDCCH. monitoring Physical Downlink Control Channel (PDCCH) candidates in a subframe using common reference signals and monitoring Enhanced Physical Downlink Control Channel (EPDCCH) candidates in the subframe using demodulation reference signals (DMRS) when the UE is configured in a first transmission mode for receiving a Physical Downlink Shared Channel (PDSCH) based on DMRS; monitoring a set of PDCCH candidates in the subframe only using CRS when the UE is configured in a second transmission mode for receiving a Physical Downlink Shared Channel (PDSCH) based on CRS, wherein the set of PDCCH candidates is determined based on whether both PDCCH candidates and EPDCCH candidates are monitored by the UE in the subframe or, only PDCCH candidates are monitored by the UE in the subframe; and receiving downlink control information in the subframe in a PDCCH candidate of the monitored PDCCH candidates or in an EPDCCH candidate of the monitored EPDCCH candidates, wherein monitoring a control channel candidate comprises attempting to decode the control channel candidate using a reference signal for channel estimation purposes, wherein the UE receives an indication of a set of DCI formats for which the PDCCH candidates are monitored and a set of DCI formats for which the EPDCCH candidates are monitored, and wherein the set of DCI formats for which the PDCCH candidates are monitored and aggregation levels at which the PDCCH candidates are monitored depend on whether the UE is monitoring only the PDCCH or monitoring both the PDCCH and the EPDCCH.
