Problems solved by technology

When this situation occurs, the method disclosed in R2-060374 cannot generate a local non-receipt signal, causing the retransmission of the corresponding packet to start only after the receiving end outputs the status reporting unit, which reduces the transmission efficiency

Embodiment Construction

[0021] Please refer to FIG. 1 , which is a functional block diagram of a wireless communication device 100 . For simplicity, FIG. 1 only shows an input device 102 , an output device 104 , a control circuit 106 , a CPU 108 , a storage device 110 , a program code 112 and a transceiver 114 of the wireless communication device 100 . In the wireless communication device 100, the control circuit 106 executes the program code 112 stored in the storage device 110 through the central processing unit 108, thereby controlling the operation of the wireless communication device 100, which can receive user input through the input device 102 (such as a keyboard) signals, or output images, sounds, and other signals through the output device 104 (such as a screen, a speaker, etc.). The transceiver 114 is used for receiving or sending wireless signals, and transmitting the received signals to the control circuit 106 , or outputting the signals generated by the control circuit 106 by radio. In ...

Abstract

A method for detecting local NACK in a wireless communications system comprises an HARQ transmitter generating a local NACK signal when the HARQ transmitter gives up HARQ transmission due to expiration of a timer (302).

Description

technical field [0001] The present invention relates to a method for detecting local unreceived state in a wireless communication system and its related device, in particular to a method and its related device which can start packet retransmission in good time so as to reduce retransmission delay. Background technique [0002] The third-generation mobile communication technology can provide high spectrum utilization efficiency, unlimited coverage, high-quality, high-speed multimedia data transmission, and can meet various QoS service requirements at the same time, providing flexible and diversified Two-way transmission service, and provide better communication quality, effectively reduce communication interruption rate. However, the industry has begun to develop the next generation of mobile communication technology in response to the massive demand for high-speed data transmission and multimedia applications in the market, and the relevant specification committees are also ...
