Embodiment Construction

[0058] The technical solution in this application will be described below with reference to the accompanying drawings.

[0059] The technical solution of the present application is applicable to a scenario where a communication device and a communication device, or a communication device and a plurality of communication devices perform data transmission. For example, the solution of the present application is applicable to uplink transmission or downlink transmission in a single-user device or multi-user device scenario, and is also applicable to data transmission in a device-to-device (device to device, D2D) scenario. This application is not limited.

[0060] see figure 1 , figure 1 It is a schematic diagram of the system architecture applicable to the embodiment of the present application. like figure 1 As shown, the wireless communication system may include at least one access point (access point, AP) and one or more stations (station, STA), such as figure 1 STA1, STA2...

Abstract

The invention provides a data retransmission method and a communication device. The method comprises the steps of: when a sending end device sends data to a receiving end device and contains newly-transmitted data and retransmitted data at the same time, enabling the sending end device to adopt an independent MCS and an independent encoding mode for the newly-transmitted data and the retransmitteddata respectively, and sending the newly-transmitted data and the retransmitted data to the receiving end device through an implicit or explicit mode; and indicating the MCS and the coding mode respectively adopted by the newly transmitted data and the retransmitted data to a receiving end device. Therefore, the receiving end device demodulates the newly transmitted data and the retransmitted data respectively by adopting the respective MCS and encoding mode indicated by the transmitting end device, so that the reliability of data transmission can be improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and more specifically, to a method and a communication device for retransmitting data. Background technique [0002] In communication systems, due to the time-varying characteristics of wireless channels and multipath fading, signal transmission failures will occur. Usually, methods such as forward error correction (forward error correction, FEC) coding technology and automatic repeat request (automatic repeat-request, ARQ) are used for error control. For example, in a wireless local area network (Wireless Local Area Network, WLAN), when an access point (access point, AP) sends data to a station (station, STA), if the STA successfully receives the data, the STA will feed back an acknowledgment (acknowledge, STA) to the AP. ACK) frame. If the STA fails to receive data successfully, it will not feedback any frame. If the AP does not receive any feedback, it will retransm...
