A computer-implemented method for providing multi-cell, multi-point single user, SU, multiple input and multiple output, MIMO, transmissions, the method comprising: receiving and processing, by a user equipment, UE, control information received from a first transmission point or a second transmission point, wherein the control information includes an indication of a parameter set for determining a quasi co-location, and wherein the control information indicates a channel state information, CSI, reference signal, RS, to be used for reporting CSI according to a first CSI feedback process for individual links of the first transmission point, and antenna ports associated with the CSI-RS are not assumed as quasi co-located; determining, by the UE, based on the indicated parameter set, a quasi co-location assumption to be used for estimating channel characteristics for reception of the first set of one or more independent transmission layers and for reception of the second set of one or more independent transmission layers; estimating, by the UE, the CSI of the first CSI feedback process for reception of the first set of one or more independent transmission layers using first receive antennas and a CSI of a second CSI feedback process for reception of the second set of one or more independent transmission layers using second receive antennas based on the quasi co-location assumption, the CSI of the first CSI feedback process comprising a channel quality indicator, CQI, a precoding matrix indicator, PMI, and a rank indicator, RI, wherein the RI is assumed for the first CSI feedback process based on an RI of the second CSI feedback process corresponding to the second transmission point and the PMI and the CQI of the first CSI feedback process are determined independently from a PMI and CQI of the second CSI feedback process; and based on the estimated channel characteristics, receiving and processing, by the user equipment, UE, the first set of one or more independent transmission layers received in a downlink channel from the first transmission point; and receiving and processing, by the UE, the second set of one or more independent transmission layers received in a downlink channel from the second transmission point. receiving and processing, by a user equipment, UE, control information received from a first transmission point or a second transmission point, wherein the control information includes an indication of a parameter set for determining a quasi co-location, and wherein the control information indicates a channel state information, CSI, reference signal, RS, to be used for reporting CSI according to a first CSI feedback process for individual links of the first transmission point, and antenna ports associated with the CSI-RS are not assumed as quasi co-located; determining, by the UE, based on the indicated parameter set, a quasi co-location assumption to be used for estimating channel characteristics for reception of the first set of one or more independent transmission layers and for reception of the second set of one or more independent transmission layers; estimating, by the UE, the CSI of the first CSI feedback process for reception of the first set of one or more independent transmission layers using first receive antennas and a CSI of a second CSI feedback process for reception of the second set of one or more independent transmission layers using second receive antennas based on the quasi co-location assumption, the CSI of the first CSI feedback process comprising a channel quality indicator, CQI, a precoding matrix indicator, PMI, and a rank indicator, RI, wherein the RI is assumed for the first CSI feedback process based on an RI of the second CSI feedback process corresponding to the second transmission point and the PMI and the CQI of the first CSI feedback process are determined independently from a PMI and CQI of the second CSI feedback process; and based on the estimated channel characteristics, receiving and processing, by the user equipment, UE, the first set of one or more independent transmission layers received in a downlink channel from the first transmission point; and receiving and processing, by the UE, the second set of one or more independent transmission layers received in a downlink channel from the second transmission point.
