A method comprising: receiving, at a base station for a wireless network, measurement information from a wireless device that indicates an ability of the wireless device to receive data from a coordinating set of base stations (111; 121; 131; 141) via a plurality of separate communication links (113; 123; 133; 143); coordinating transmission of one or more protocol data units to the wireless device from the coordinating set of base stations, the coordinating to include exchanging information via one or more backhaul communication channels coupling base stations included in the coordinating set of base stations; and causing the one or more protocol data units to be transmitted to the wireless device from the coordinating set of base stations via the plurality of separate communication links based, at least in part, on the exchanged information, wherein: the measurement information includes channel state information for each communication link from among the plurality of separate communication links, the channel state information for each communication link to include at least one of a precoding matrix indicator, a rank indicator or a channel quality indicator; the information exchanged via the backhaul communication channel includes scheduling information to transmit the one or more protocol data units, one or more precoding matrix indicators associated with a communication link via which the one or more protocol data units are transmitted, a subframe index associated with the one or more protocol data units, a time of a beginning of transmission of the one or more protocol data units, and hybrid automatic repeat request 'HARQ' information associated with the one or more protocol data units; and for each protocol data unit, scheduling information, a precoding matrix indicator, a subframe index, a time of a beginning of transmission and HARQ information for that protocol data unit is incorporated in a GPRS tunneling protocol user-plane 'GTP-u' extension header and included with the protocol data unit to be transmitted to the wireless device. receiving, at a base station for a wireless network, measurement information from a wireless device that indicates an ability of the wireless device to receive data from a coordinating set of base stations (111;
