摘要： A radio device/user equipment determines that a later received grant of bundled uplink resources collides with an earlier received grant of bundled uplink resources. The earlier received grant has associated with it an active re-transmission process. In response to that collision determination, at least a re-transmission (HARQ) buffer associated with the earlier received grant is flushed. In one embodiment all HARQ buffers are flushed; in another the HARQ buffer associated with the earlier received grant is flushed while the one associated with the later received grant is not. Several ways are described to determine whether there is a collision: whether the later received grant aligns with a boundary of the resources granted by the earlier received grant, and whether there is an actual collision among the different HARQ processes. Calculating HARQ process numbers is also described where an offset is used to account for the grants allocating bundled TTIs.
