Problems solved by technology

[0007] Therefore, all stations in the IBSS system need to receive and analyze the MAC receiving address in the Data field before knowing whether the information packet should be received, so the amount of information processing is relatively large, which makes the power consumption of the IBSS stations relatively large, increasing processing cost

Abstract

The invention relates to a method and a device of sending and receiving an information packet of an independent basic service set (IBSS) system. The receiving method of the information packet of the IBSS system comprises receiving a first field of the information packet of the IBSS, wherein the first field comprises the first part of address information of a receiving end, carrying out matching according to the first part of the address information and own second part of address information, continuing to receive a second field of the information packet of the IBSS, wherein the second filed comprises the first address information of the receiving end if the matching is achieved, carrying out matching according to the first address information and the second address information, continuing to receiving the information packet of the IBSS is given up if the matching fails, and continuing to receiving the information packet of the IBSS if the matching is achieved. According to the method and the device of sending and receiving the information packet of the IBSS system, the matching is carried out after the first field of the IBSS information packet is received, the second field does not need to continue to be received if the matching fails, the receiving of the information packet is given up, and therefore processing time is saved, processing procedures are reduced, and power consumption is effectively reduced.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for sending and receiving information packets in an IBSS system. Background technique [0002] figure 1 It is a schematic diagram of a wireless local area network in the prior art, as shown in the figure, a basic service set (Basic service set, BSS) is a basic component of a wireless local area network (Wireless Local area network, WLAN). Stations (Stations, STAs) that are within a specific coverage area and have certain associations form a BSS, such as BBS1, BBS2, and BBS3 in the figure. [0003] The most basic form of association between various BBSs is that each station communicates directly with each other in an ad hoc network, which is called an independent BSS (Independent BSS, IBSS), such as figure 1 BSS1 in. IBSS is also called ad hoc network. The IBSS system can contain at least 2 stations, the simplest is only two stations, such as BBS2 and BB...
