摘要： A first user equipment UE operating in a first/strong transmission mode determines that a second UE is operating in a second/weak mode and is allocated a same radio resource as the first UE. The first UE determines a transport format for transmissions to the second UE and uses that to decode and cancel a transmission received on the radio resource which is directed to the second UE, mitigating interference with a further transmission directed to the first UE. Various examples are given of specific resource allocation signaling used to determine that the second UE is operating in the second mode and is allocated the same radio resource, such as implicitly by a specific downlink control indication format or an explicit indication in a resource allocation directed to the first UE. The first UE can determine the transport format of the second UE from network signaling.
