Abstract:
Method performed by a network node (210) to indicate a first and a second set of antenna ports. The network node (210) indicates (803) to a wireless device (250) at least one of: a) a first indication of a first set (M′) of antenna ports for first measurements on first radio signals, the first measurements associated with periodic reporting, and b) a second indication of a second set (M) of antenna ports for second measurements on second radio signals, the second measurements associated with aperiodic reporting. The first set is different than the second set. The periodic and the aperiodic reporting are by the wireless device (250) and correspond to a same Channel State Information, CSI, process. The network node (210) also transmits (804), to the wireless device (250), the first radio signals, periodically, over the first set and the second radio signals over the second set.
