Systems and methods for configuring transmissions in a wireless network

An apparatus (700) for configuring communication in a wireless communication system, the apparatus comprising:

• a transmitter (710) configured to transmit feedback information to a wireless communication device in a first cell served by the apparatus;
• and
• a processor (702) configured to:
• obtain information pertaining to an almost blank subframe (ABS) configuration to be used in a second cell;
• determine based on the obtained information a transmission configuration for a downlink control channel carrying feedback information for one or more wireless communication devices, wherein the transmission configuration comprises transmission power level, transmission format, or both;
• and
• transmit feedback information for an uplink transmission to the one or more wireless communication devices using the determined transmission configuration.

A method for configuring a wireless transmission, the method comprising:

• obtaining, at a first network node serving a first cell, information pertaining to a type of an almost blank subframe (ABS) configuration to be used in a second cell;
• determining based on the obtained information a transmission configuration for a downlink control channel carrying feedback information for one or more wireless communication devices, wherein the downlink control channel is to be transmitted in at least one subframe in the first cell that does not overlap with any ABS subframes in the second cell, and wherein the transmission configuration comprises a transmission power level, a transmission format, or both;
• and
• transmitting feedback information for an uplink transmission to said one or more wireless communication devices using the determined transmission configuration.
