Embodiment Construction

[0022] Embodiments of the present invention improve the existing HARQ process and base station equipment, and aim at the situation that the base station does not receive any feedback information about the success of HARQ packet reception sent by the terminal, through the improved HARQ process and base station equipment, thereby Ensure the successful decoding of HARQ packets, thereby improving the system spectrum efficiency.

[0023] The reasons why the base station cannot receive any feedback information about the success of receiving the HARQ packet sent by the terminal may include:

[0024] When the base station assigns downlink resources for the terminal to transmit data packets, the terminal does not decode or cannot successfully decode the downlink resource indication information, resulting in the inability to know the downlink resources allocated by the base station. In this way, the terminal naturally cannot receive the transmission from the base station HARQ packet, it...

Abstract

A hybrid automatic repeat request method and a base station device are provided. The method includes: the base station assigns the downlink resource for a terminal and transmits the first sub-packet of the data packet to the terminal in the hybrid automatic repeat request (HARQ) manner by using the downlink resource; if the base station does not receive any feedback information sent by the terminal about whether the data packet is successfully received or not in a set time slot, then the base station assigns the new downlink resource for the terminal and retransmits the first sub-packet of the data packet to the terminal by using the newly assigned downlink resource.

Description

technical field [0001] The present invention relates to the communication field, in particular to a hybrid automatic retransmission processing method and base station equipment. Background technique [0002] In the communication system, the base station refers to the equipment that provides services to the terminal. The base station communicates with the terminal through the uplink and downlink. The downlink (forward) refers to the direction from the base station to the terminal, and the uplink (reverse) refers to the direction from the terminal to the base station. . Multiple terminals can simultaneously send data to the base station through the uplink, and can also receive data from the base station through the downlink at the same time. [0003] In order to overcome the influence of wireless mobile channel time-varying and multipath fading on signals, wireless communication systems can use error control methods based on forward error correction (Forward Error Correction,...
