Scheduling and coordination in a wireless network

A method performed by a user equipment (UE), the method comprising:

• simultaneously receiving, by the UE, a plurality of orthogonal frequency division multiplex (OFDM) streams from a first base station;
• transmitting, by the UE, channel condition information to the first base station and to a second base station;
• and
• receiving by the UE, in response to the transmitted channel condition information and corresponding scheduling indicated by the first and second base stations, a first single-stream OFDM transmission from the first base station and a second single-stream OFDM transmission from the second base station, wherein the first and second single-stream transmissions are time-aligned such that their respective arrivals at the UE occur within a cyclic prefix portion of one another.

A base station comprising:

• a receiver;
• a transmitter;
• and
• a processor;
• wherein:
• the transmitter and the processor are configured to transmit a plurality of orthogonal frequency division multiplexing (OFDM) streams to a user equipment (UE);
• the receiver and the processor are configured to receive channel condition information from the UE and to exchange the channel condition information with a second base station;
• and
• the transmitter and the processor are further configured, based on scheduling determined using the channel condition information, to transmit single-stream OFDM transmissions to the UE in coordination with single-stream OFDM transmissions to the UE by the second base station such that the respective single-stream OFDM transmissions arrive at the UE fall within a cyclic prefix portion of one another.
