Abstract
Methods and apparatuses are provided for a User Equipment (UE) to receive control information. A Downlink Control Information (DCI) format to be monitored is identified. A number of Enhanced Physical Downlink Control Channel (EPDCCH) candidates are identified based on the identified DCI format. Control information is received based on the identified number of EPDCCH candidates.
Claims16
A method for a user equipment (UE) to receive control information, comprising:
- identifying a downlink control information (DCI) format to be monitored;
- identifying a number of enhanced physical downlink control channel (EPDCCH) candidates based on the identified DCI format and a number of physical resource block (PRB) pairs;
- and
- receiving control information based on the identified number of EPDCCH candidates.
A method for a base station to transmit control information, comprising:
- transmitting control information,
- wherein the control information is received by a user equipment (UE) based on a number of enhanced physical downlink control channel (EPDCCH) candidates, and
- wherein the number of EPDCCH candidates is identified by the UE based on a downlink control information (DCI) format to be monitored and a number of physical resource block (PRB) pairs.
A user equipment (UE) to receive control information, comprising:
- a controller configured to identify a downlink control information (DCI) format to be monitored, and identify a number of enhanced physical downlink control channel (EPDCCH) candidates based on the identified DCI format and a number of physical resource block (PRB) pairs;
- and
- a transceiver configured to receive control information based on the identified number of EPDCCH candidates.
A base station to transmit control information, comprising:
- a transceiver configured to transmit control information,
- wherein the control information is received by a user equipment (UE) based on a number of enhanced physical downlink control channel (EPDCCH) candidates, and
- wherein the number of EPDCCH candidates is identified by the UE based on a downlink control information (DCI) format to be monitored and a number of physical resource block (PRB) pairs.
