Embodiment Construction

[0020] The specific implementation of the data transmission method and system between the wireless access point and the terminal of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] see figure 1 , figure 1 It is a flowchart of a data transmission method between a wireless access point and a terminal in an embodiment.

[0022] A data transmission method between a wireless access point and a terminal, comprising the following steps:

[0023] Step S120: After sending the beacon frame to the terminal, wait for the inter-frame interval time, and then send a request to send frame to the terminal; wherein, the request to send frame includes the occupation time of the channel;

[0024] In step S120, the interframe space may be a centralized interframe space (PIFS, Point Coordination Function Interframe Space) or a distributed interframe space (DIFS, Distributed Coordination Function Interframe Space); sending the beacon f...

Abstract

The invention provides a data transmission method and a system for a wireless access point and a terminal. The method comprises the following steps: waiting for an interframe spacing interval after a beacon frame is sent to the terminal; transmitting a request transmission frame to the terminal, wherein the request transmission frame comprises occupied moment of a channel; receiving a downlink allowing transmission frame returned by the terminal, wherein the terminal generates the download allowing transmission frame after receiving the request transmission frame; transmitting a download data frame to the terminal at the occupied moment of the channel, and receiving a download acknowledge character returned by the terminal, wherein the terminal generates the download acknowledge character after a short interframe spacing interval after receiving the download data frame at the occupied moment of the channel. The request transmission frame is transmitted through the terminal during data transmission, and comprises the occupied moment of the channel, thus the problem of throughput drop of the system under the multi-user circumstance can be solved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a data transmission method between a wireless access point and a terminal and a data transmission system between a wireless access point and a terminal. Background technique [0002] At present, the main access method between the WLAN (Wireless Local Area Networks, wireless local area network) network and the terminal is DCF (Distributed Coordination Function, distributed coordination function) access, which is based on the competition mechanism to apply for and occupy the communication channel , when performing uplink and downlink data interaction between a wireless access point (AP, Wireless Access Point) and a terminal, distributed data interaction is adopted. [0003] Under a small number of users, the distributed data interaction method of DCF is a relatively high method for channel utilization. However, when the number of users increases, due to the ...
