1. A method for use in a wireless device, the method comprising:

  • receiving, via a first cell of a first transmission point of a first base station, at least one message indicating channel state information (CSI) measurement resources for each cell of a subset of cells, wherein the subset of cells comprises the first cell of the first transmission point and at least one second cell of a second transmission point;

    measuring, based on the CSI measurement resources, CSI for the subset of cells;

    quantizing the measured CSI jointly across cells of the subset of cells;

    transmitting, to the first base station, the jointly quantized CSI;

    receiving, via the first transmission point of the first base station, at least one resource assignment for at least one packet; and

    receiving signals simultaneously via the first cell of the first transmission point and the at least one second cell of the second transmission point, wherein the signals correspond to the at least one packet.
