METHOD OF RE-ORDERING RECEIVED DATA BLOCKS IN HYBRID AUTOMATIC REPEAT REQUEST TELECOMMUNICATION SYSTEM

摘要

A method of telecommunication transmits blocks of data between a user equipment and a station using parallel hybrid automatic repeat request processes. The station includes a scheduler that signals to the user equipment allocations of resources and parameters for transmission and re-transmission of the data blocks and a set of reception buffers that receive and re-order the data blocks from the user equipment. The scheduler assigns a reception index to the corresponding scheduled reception and assigning reception buffers to received data blocks as a function of the respective originally scheduled reception indexes identifying time slots scheduled for reception. A data block newly transmitted by the user equipment and received in its scheduled time slot is assigned to the reception buffer corresponding to the new reception index. A data block that is re-transmitted by the user equipment and received in a time slot later than its originally scheduled time slot is assigned to the reception buffer corresponding to the same reception index as its originally scheduled reception. The data blocks to which the scheduler assigns a reception index and a reception buffer of the set are Media Access Control Packet Data Units (‘MAC PDUs’).
