Abstract

The embodiment of the invention discloses a multi-resource unit transmission indication method and related equipment. The method comprises that the first equipment generating an EHT TB PPDU, the EHT TB PPDU comprising a resource unit indication field, the resource unit indication field being used for indicating a first resource unit used by the first equipment for transmitting the EHT TB PPDU, the first resource unit being included in a resource unit allocated to the first equipment; and the first equipment sends the EHT TB PPDU to the second equipment. According to the embodiment of the invention, the RU used by the first equipment for actually transmitting the EHT TB PPDU can be indicated. The technical scheme provided by the invention can be applied to Wi-Fi systems such as 802.11 ax, 802.11 be and the like.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method for indicating multi-resource unit transmission and related equipment. Background technique [0002] In a traditional wireless local area network (Wireless Local Area Network, WLAN), when each station (station) needs to send uplink data, it will occupy the entire channel for data transmission through competition, and the spectrum utilization rate is low. The Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.11ax protocol standard proposes a trigger frame-based scheduled uplink transmission method. In this transmission method, before the station transmits an efficient trigger-based physical layer protocol data unit (High Efficient Trigger Based Physical layer Protocol Data Unit, HE TB PPDU), it will send the resource unit (resource unit, RU) where it is allocated Carrier sense is perform...
