Abstract

See full text

It is presented a method for transmitting interference cancellation information to a first user equipment, UE. The method is performed in a first network node and comprises the steps of: determining that the first UE is connected to the first network node in a multipoint fashion such that the first UE is also connected to a second network node; obtaining first downlink scheduling information describing downlink transmission from the first network node to a second UE; and transmitting interference cancellation information to the first UE over a control channel also used by the first network node to transmit scheduling information to the first UE, the interference cancellation information comprising the first downlink scheduling information and an indicator that the interference cancellation information does not contain scheduling information for the first UE.
