Communication method, device and system

Abstract

The embodiment of the invention provides a communication method, device and system. The method comprises the following steps: a relay device receives a first data packet sent by a first device, wherein the first data packet comprises transmission opportunity sharing indication information, at least one piece of first data and destination addresses of the first data, and the transmission opportunity sharing indication information is used for indicating to perform data transmission within the transmission opportunity of the first device; and the relay device sends a second data packet accordingto the transmission opportunity sharing indication information, wherein the second data packet comprises at least one piece of first data and destination addresses of the first data, and the format ofthe second data packet is a multiuser format. By receiving the transmission opportunity sharing indication information, the first data needing to be forwarded to multiple devices is forwarded in themultiuser format according to the transmission opportunity sharing indication information, thereby realizing the simultaneous sending and receiving of the data of multiple users and improving the datatransmission efficiency in a relay communication system.

Description

technical field [0001] The communication field of the present invention particularly relates to a communication method, device and system. Background technique [0002] With the rapid development of wireless communication services, long-distance transmission may occur in the communication network. In order to ensure the stability of communication, one or more relay nodes can be added between nodes for long-distance transmission to form a transmission network containing relay nodes. network. When the relay node works in the transmission network, the relay node (Relay) receives the data sent by the upper layer relay node or Root Access Point (Root Access Point, referred to as Root AP), and forwards the data to the lower layer Relay or station (Station, referred to as STA). [0003] During the above data transmission process, the upper layer nodes that send the data need to compete for the channel. After successfully competing for the channel, the data will be sent. In order ...
