Abstract

The invention discloses an end-to-end communication method applicable to the wireless local area network. The method includes that: a station in a basic service set requests an access point for uplink transmission resources; after acquiring the uplink transmission resources, the station transmits the uplink resources to the access point at the corresponding resource position; the access point caches the unlink data transmitted by the station and judges whether data available for network encoding and transmission exists or not; if yes, network codes are transmitted; if not, the data are transmitted normally. The network encoding method is applied, so that time slots occupied by end-to-end communication forwarded through the access point are reduced, and system performance is improved.

Description

technical field [0001] The invention relates to a wireless local area network, in particular to an end-to-end communication method suitable for the wireless local area network. Background technique [0002] In a wireless local area network, a base station is also called an access point (AP, access point). In a wireless local area network, communication between stations (STAs) often needs to be forwarded through the access station as a relay, as shown in the attached figure 1 shown. Therefore, an interaction between sites needs to occupy 4 time slots: STA1—>AP, AP—>STA2, STA2—>AP, AP—>STA1, so the efficiency of the system is relatively low, and due to the network coding technology in The performance advantage in the relay system introduces network coding technology into the wireless LAN system to improve the efficiency of end-to-end communication. [0003] Basic network coding generally includes network coding of two time slots (performed at the physical layer) an...
