1. A method for transmitting an extended physical downlink control channel (E-PDCCH), comprising:
- transmitting control information in at least one time-frequency resource unit that would otherwise be used to carry a physical downlink shared channel (PDSCH), wherein the E-PDCCH and at least one PDSCH are multiplexed in a transmission time interval, and wherein a first set of configuration of the E-PDCCH is semi-statically signaled and a second set of configuration of the E-PDCCH is dynamically signaled.

Abstract
A method is provided for transmitting an extended physical downlink control channel (E-PDCCH). The method comprises transmitting control information in at least one time-frequency resource unit that would otherwise be used to carry a physical downlink shared channel (PDSCH). The E-PDCCH and at least one PDSCH are multiplexed in a transmission time interval. A first set of configuration of the E-PDCCH is semi-statically signaled and a second set of configuration of the E-PDCCH is dynamically signaled.

34. An access node, comprising:
-
a first configuration circuitry configured to determine a first set of configuration of an extended physical downlink control channel (E-PDCCH) and provide the first set of configuration to a user equipment (UE) via semi-static signaling; a second configuration circuitry configured to determine a second set of configuration of the E-PDCCH and provide the second set of configuration to the UE via dynamic signaling; and a transmitting circuitry configured to transmit the E-PDCCH in at least one time-frequency resource unit that would otherwise be used by a physical downlink shared channel (PDSCH). - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
