Abstract: A wireless communication method, a terminal device and a network device are provided. The method includes: updating mapping information, wherein the mapping information is traffic identifier-to-link mapping information at a sending end; generating an indication message; and sending the indication message to a receiving end, wherein the indication message is used for indicating that the receiving end does not need to respond, with regard to the indication message, to the sending end, and the indication message comprises: updated mapping information, such that the receiving end updates, according to the updated mapping information, traffic identifier-to-link mapping information at the receiving end.

Abstract: The embodiments of the present disclosure provide a data retransmission method and an access point device, capable of achieving downlink data retransmission in a multi-AP cooperation scenario, which can reduce the number of downlink data retransmissions and transmission delay, thereby improving user experience. The data retransmission method includes: transmitting, by a first access point device, first request information when the first access point device fails to transmit a first data frame to a station device, the first request information requesting a second access point device to retransmit the first data frame, and the first access point device and the second access point device belonging to one operation set.
