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). If it is determined that a collision will occur, the method dynamically allocates the first user equipment to another uplink resource to avoid the collision, while if it is determined that the collision will not occur, the first user equipment is not dynamically allocated another uplink resource so that the first user equipment sends its transmission using the persistently assigned uplink resource. The embodiments of this invention pertain to both the base station (e.g., an evolved Node-B) and the user equipment. | 04-23-2009 |
