Scheduling and coordination in a wireless network

A method performed by a network device, the method comprising:

• determining, by the network device, channel quality of a radio channel in a wireless network based on information from a user equipment (UE);
• receiving, by the network device from a first network device, first assistance information that provides channel conditions at the first network device;
• dynamically scheduling, by the network device on a time and frequency basis, a first plurality of orthogonal frequency division multiplexing (OFDM) streams based on the received first assistance information and the channel quality;
• sending, by the network device to the first network device, second assistance information to cause scheduling adjustment of a second plurality of OFDM streams, wherein the first plurality of OFDM streams and the second plurality of OFDM streams are substantially synchronized;
• and
• wherein the second assistance information provides channel conditions in relation to the network device.

A user equipment (UE) comprising:

• a transceiver configured to receive N orthogonal frequency division multiplexing (OFDM) data streams from a first network device and a second network device, wherein M data streams are from the first network device and N-M of the data streams are from the second network device;
• wherein the M data streams and the N-M data streams are substantially synchronized;
• wherein transmissions from the first network device and the second network device are scheduled and coordinated based on a determined channel quality of a radio channel between the first network device and the UE;
• wherein a first number of data streams used for communication with the UE in a time period and a second number of data streams transmitted within the time period are adjusted based on the determined channel quality;
• and
• wherein the scheduling further includes adjusting a portion of frequency resources used by the first network device for the first number of data streams based on the determined channel quality.
