Abstract
A method for a base station to transmit a Demodulation Reference Signal (DMRS) for a control channel in a wireless communication system is disclosed. The method includes transmitting a DMRS for an Enhanced-Physical Downlink Control Channel (E-PDCCH) to a user equipment, wherein a DMRS sequence corresponding to the transmitted DMRS is formed using an initial sequence calculated based on a virtual cell ID.
Claims17
A method for a base station to transmit a Demodulation Reference Signal (DMRS) for a control channel in a wireless communication system, the method comprising:
- transmitting a DMRS for an Enhanced-Physical Downlink Control Channel (E-PDCCH) to a user equipment,
- wherein a DMRS sequence corresponding to the transmitted DMRS is formed using an initial sequence calculated based on a virtual cell ID,
- wherein the virtual cell ID is configured by Radio Resource Control (RRC) signaling.
(canceled)
A method for a user equipment to receive a Demodulation Reference Signal (DMRS) for a control channel in a wireless communication system, the method comprising:
- receiving a DMRS for an Enhanced-Physical Downlink Control Channel (E-PDCCH) from a base station,
- wherein a DMRS sequence corresponding to the received DMRS is formed using an initial sequence calculated based on a virtual cell ID,
- wherein the virtual cell ID is configured by Radio Resource Control (RRC) signaling.
(canceled)
A base station for transmitting a Demodulation Reference Signal (DMRS) for a control channel in a wireless communication system, the base station comprising:
- a Radio Frequency (RF) unit;
- and
- a processor,
- wherein the processor controls the RF unit to transmit a DMRS for an Enhanced-Physical Downlink Control Channel (E-PDCCH) to a user equipment, and a DMRS sequence corresponding to the transmitted DMRS is formed using an initial sequence calculated based on a virtual cell ID,
- wherein the virtual cell ID is configured by Radio Resource Control (RRC) signaling.
