Abstract

The embodiment of the present invention discloses a data transmission method and device for mode switching based on link complexity. The method includes sending a single data frame to multiple terminal devices, and after receiving feedback information from the multiple terminal devices, according to The feedback information is used to send the next data frame; the first communication quality parameter is determined, and after a preset time interval, the second communication quality parameter is determined; the first communication quality parameter is corrected according to the first communication quality parameter and the second communication quality parameter The quality change parameter, when the quality change parameter satisfies the frame data continuous sending condition, continuously send multiple data frames to the multiple terminal devices, without waiting for feedback information before sending the data frames. This solution optimizes the data transmission mechanism, which can be adjusted in time according to the channel conditions, and improves the data transmission efficiency.

Description

technical field [0001] The embodiments of the present application relate to the field of data transmission, and in particular to a data transmission method and device for performing mode switching based on link complexity. Background technique [0002] Since information will be lost during channel transmission, in order to maintain the integrity of the information, it is necessary to retransmit the information until all the information is received. Depending on the link conditions, adaptive or non-adaptive data transmission, as well as synchronous and asynchronous data transmission can be adopted. Wherein, the adaptive transmission means that the sending end changes part of the transmission parameters according to the actual channel state information. Non-adaptive transmission means that the transmission parameters are already known to the receiving end, so the signaling containing the transmission parameters does not need to be transmitted again in the non-adaptive transmi...
