1. A wireless device comprising:
a) one or more communication interfaces; b) one or more processors; and c) memory storing instructions that, when executed, cause said wireless device to:
i) receive from a first base station at least one control message indicating channel state information (CSI) measurement resources of a subset of cells, a CSI measurement resource corresponding to a plurality of resource elements in a plurality of subframes on an antenna port of a cell in said subset of cells, cells in said subset of cells belonging to at least two base stations comprising said first base station or belonging to at least two sectors of said first base station;ii) measure CSI employing at least said CSI measurement resources of said subset of cells;iii) quantize said measured CSI jointly across cells in said subset of cells;iv) encode and transmit said jointly quantized CSI according to a physical uplink control channel format;v) receive, from said first base station on one serving cell in said subset of cells, at least one resource assignment for at least one data packet; andvi) simultaneously receive signals from multiple cells in said subset of cells, said signals carrying said at least one data packet for said wireless device, said multiple cells belonging to said at least two base stations or belonging to at least two sectors of said first base station. |
