20090103440 | Collision avoidance for uplink VoIP transmission - Disclosed is a method the includes determining if a collision will occur between a transmission from a first user equipment that uses a persistently assigned uplink resource (such as for VoIP packet transmissions) and a retransmission from a second user equipment that uses a synchronous non-adaptive automatic repeat request procedure (e.g., synchronous, non-adaptive HARQ).
