A method performed by a network node of a wireless network to provide communication services to a target terminal, the method comprising: transmitting a plurality of data streams to one or more terminals in a cell being served by the network node, wherein for each data stream, the network node also transmits a corresponding configuration information that identifies air interface resources allocated to that data stream, and wherein an interfering stream is a data stream intended for a terminal other than the target terminal, and an interfering configuration is the configuration information corresponding to the interfering stream; characterized in that the method further comprising: determining whether the target terminal will benefit from interference information before transmitting the plurality of data streams to the one or more terminals, wherein the step of determining whether the target terminal will benefit from the interference information, comprises: determining whether the target terminal is in a data state; and determining whether the target terminal is interference cancellation, IC, capable; and transmitting the interference information to the target terminal over a shared control channel when it is determined that the target terminal is in the data state and that the target terminal is IC capable, wherein in the step of transmitting the interference information to the target terminal, the interfering configuration and/or an identity of the terminal are transmitted as the interference information, and wherein the interference information is generated according to a predetermined group ID, the group ID being understood by a plurality of terminals to indicate that the interference information includes the interfering configuration. transmitting a plurality of data streams to one or more terminals in a cell being served by the network node, wherein for each data stream, the network node also transmits a corresponding configuration information that identifies air interface resources allocated to that data stream, and wherein an interfering stream is a data stream intended for a terminal other than the target terminal, and an interfering configuration is the configuration information corresponding to the interfering stream; characterized in that the method further comprising: determining whether the target terminal will benefit from interference information before transmitting the plurality of data streams to the one or more terminals, wherein the step of determining whether the target terminal will benefit from the interference information, comprises: determining whether the target terminal is in a data state; and determining whether the target terminal is interference cancellation, IC, capable; and transmitting the interference information to the target terminal over a shared control channel when it is determined that the target terminal is in the data state and that the target terminal is IC capable, wherein in the step of transmitting the interference information to the target terminal, the interfering configuration and/or an identity of the terminal are transmitted as the interference information, and wherein the interference information is generated according to a predetermined group ID, the group ID being understood by a plurality of terminals to indicate that the interference information includes the interfering configuration. determining whether the target terminal will benefit from interference information before transmitting the plurality of data streams to the one or more terminals, wherein the step of determining whether the target terminal will benefit from the interference information, comprises: determining whether the target terminal is in a data state; and determining whether the target terminal is interference cancellation, IC, capable; and determining whether the target terminal is in a data state; and determining whether the target terminal is interference cancellation, IC, capable; and transmitting the interference information to the target terminal over a shared control channel when it is determined that the target terminal is in the data state and that the target terminal is IC capable, wherein in the step of transmitting the interference information to the target terminal, the interfering configuration and/or an identity of the terminal are transmitted as the interference information, and wherein the interference information is generated according to a predetermined group ID, the group ID being understood by a plurality of terminals to indicate that the interference information includes the interfering configuration.
