US 8,413,002 B2 · Method of performing ARQ procedure for transmitting high rate data

Abstract

A data transmission method using automatic repeat request (ARQ) in a radio interface protocol system consisting of a plurality of layers is provided. The method includes delivering, from an upper layer to a lower layer, a data block stored in an ARQ buffer, the ARQ buffer storing a plurality of data blocks to be transmitted in response the lower layer, the data block; delivering, from the upper layer to the lower layer, a new data block stored in the ARQ buffer if a delivery success message is received from the lower layer, the delivery success message indicating successful transmission of the data block; and shifting a window of the ARQ buffer. The present invention can effectively use radio resources since an ARQ procedure does not require a polling process and a process of receiving a status PDU, and is suitable for high rate data transmission.

A data transmission method using automatic repeat request (ARQ) in a radio interface protocol system comprising a plurality of layers, the method comprising:

storing a plurality of data blocks in an ARQ buffer for transmission;
delivering a first data block of the plurality of stored data blocks from a radio link control (RLC) layer to a medium access control (MAC) layer;
transmitting the first data block by the MAC layer in response to an ARQ;
delivering a second data block of the plurality of stored data blocks from the RLC layer to the MAC layer if a delivery success message is received from the MAC layer that indicates successful transmission of the first data block;
and
shifting a window of the ARQ buffer.
