摘要:
A method of providing interference avoidance in uplink CoMP may include generating an orthogonal frequency division multiplexing (OFDM) symbol for uplink transmission to coordinated multi-point (CoMP) cells, and providing a cyclic-prefix and a cyclic-postfix for the OFDM symbol generated to reduce uplink interference without backhaul transmission for delay or timing advance information. A corresponding apparatus and computer program product are also provided. An alternative method of providing interference avoidance in uplink CoMP may include measuring timing differences between downlink signals received at a mobile terminal in connection with coordinated multi-point (CoMP) transmission from a serving cell and one or more coordinating cells and adjusting uplink transmission timing for signals to be transmitted from the mobile terminal based on the timing differences measured. A corresponding apparatus and computer program product are also provided.
