Abstract

The embodiment of the invention relates to the field of communication, in particular to a data confirmation method and device in the field of communication. The data confirmation method comprises the steps that an STA sends a data frame; and the STA sends a confirmation request after the X duration from the end of sending of the data frame, and the transmission delay of a backhaul link is passed when the X duration is greater than or equal to AP, and the confirmation request is the confirmation request of the data frame. According to the embodiment of the invention, the STA sends the confirmation request after the X time length after the sending of the data frame is finished, and the transmission delay of the backhaul link is passed when the X duration is greater than or equal to AP, and the confirmation of the uplink joint receiving of the AP side is completed on the premise of avoiding the waste of air interface resources.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular to a data confirmation method and device in the communication field. Background technique [0002] In outdoor scenarios, such as high-speed railways, highways, etc., the power of STAs is usually relatively small compared with that of APs, so STAs usually cannot send uplink data to their APs correctly. In this case, multiple APs need to simultaneously receive the uplink data sent by the STA and share and confirm the received uplink data, so as to increase the correctness and efficiency of uplink data transmission. [0003] WLAN transmits data through the wireless air interface, and the data is often not successfully received by the receiver due to interference and poor channel environment. In order to determine whether the data is successfully received by the receiver, an acknowledgment mechanism is introduced in the 802.11 standard. [0004] Then, in the a...
