1. An apparatus comprising at least one processor and at least one memory including computer code for one or more programs, the at least one memory and the computer code configured, with the at least one processor, to cause the apparatus at least to:
cause scheduling information to be transmitted to a plurality of communication devices and control information to be transmitted to at least one communication device of the plurality of communication devices, said control information controlling in the respective communication device at least one of triggering an inter communication device interference reduction mechanism and parameters of the inter communication device interference reduction mechanism, wherein the control information includes a time-frequency information, allocated reference signal and transmission power signalled together with the scheduling information and wherein the control information is signalled in a half-duplex (HD) carrier,
wherein the at least one memory and the computer code are configured, with the at least one processor, to cause the apparatus to:
receive an inter-UE interference avoidance/reduction announcement signal wherein the announcement signal may uses the reference signal,
determine as a first determination that an inter communication device interference reduction mechanism between a plurality of said plurality of communication devices is required based on inter-user equipment (UE) avoidance control information,
monitor for an inter-UE interference reduction announcement signal,
receive a transmission of downlink data,
determine as a second determination to transmit a scheduled uplink communication based upon the outcome of the monitoring for the inter-UE interference reduction announcement signal,
transmit on a scheduled uplink resource based on a negative determination of the inter communication device interference reduction mechanism between a plurality of said plurality of communication devices being required based on inter-user equipment (UE) avoidance control information or a positive determination to transmit the scheduled uplink communication based upon the outcome of the monitoring for the inter-UE interference reduction announcement signal, and
transmit a scheduled uplink transmission upon a determination that the communication device interference reduction mechanism is not required.
