Problems solved by technology

[0011] In the existing multicast packet transmission process, all stations in the BSS receive the multicast packet, and can determine whether the multicast packet is sent to itself after receiving the address at the MAC layer. The transmission method is cumbersome and consumes a lot of power

Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] Firstly, the structure of the VHT-SIG-A (VHT Signal Afield, very high throughput signaling A field) of the physical layer frame format in 802.11 will be described.

[0044] The VHT-SIG-A field is divided into two parts, VHT-SIG-A1 and VHT-SIG-A2, and the content represented by VHT-SIG-A1 is shown in Table 3.

Abstract

An embodiment of the invention provides a multicast packet transporting method, a station device and a service set system and relates to the field of communication. The multicast packet transporting method, the station device and the service set system are capable of simplifying addressing modes when multicast packets are received, so that electricity is saved. The multicast packet transporting method includes: receiving VHT-SIG-A1 (very high throughput signal A1field) in a data packet; judging multicast identification of the VHT-SIG-A1, and if the multicast identification indicates that the data packet is a multicast packet, and using a belonging multicast address to match part of multicast addresses of the multicast packet in the VHT-SIG-A1; and if the belonging multicast address is unmatched with part of the multicast addresses of the multicast packet, quitting receiving of the multicast packet. The multicast packet transporting method, the station device and the service set system in the embodiment are used for transporting the multicast packets.

Description

technical field [0001] The invention relates to the communication field, in particular to a multicast packet transmission method, a station device and a service set system. Background technique [0002] The BSS (Basic service set, basic service set) is a basic component of a WLAN (Wireless Local area network, wireless local area network). STAs (Stations, stations) that are within a specific coverage area and have some association form a BSS. [0003] Within the BSS system, the 802.11ac standard can be used for communication. The 802.11ac physical layer frame format is shown in Table 1: [0004] L-STF L-LTF L-SIG VHT-SIG-A VHT-STF VHT-LTFs VHT-SIG-B Data [0005] Table 1 [0006] The meaning of each field is shown in Table 2: [0007] field describe L-STF Non-HT Short Training field L-LTF Non-HT Long Training field L-SIG Non-HT SIGNAL field VHT-SIG-A Very high throughput...
