Abstract

本申请适用于多链路的组播业务传输方法及装置。AP MLD的第一AP发送的组播业务指示信息用于指示AP MLD的一个AP是否有组播业务。该AP为第一AP或AP MLD的其他AP，STA MLD的第一STA可获知第一AP或其他AP是否有组播业务，改善了AP的组播业务通知的灵活性。该组播业务指示信息用于指示AP MLD的多个或所有AP中每个AP是否有组播业务，该第一STA即可获知多个AP是否有组播业务，避免STA MLD的各STA均需侦听各AP是否有组播业务，节省了STA MLD的功耗。本申请可应用于支持IEEE 802.11ax下一代WiFi EHT协议，如802.11be等802.11系列协议的无线局域网系统。
