Method for transmitting resource unit and communication device

The invention provides a method for sending a resource unit and a communication device. By implementing the embodiment of the invention, the sending power of the resource unit can be controlled. A method of transmitting a resource unit includes distributing subcarriers of a resource unit (RU) or a multiple resource unit (MRU) over a physical layer protocol data unit (PPDU) bandwidth or frequency subblocks of the bandwidth to generate a distributed tone RU (dRU) or a distributed MRU (dMRU) associated with an uplink (UL) trigger-based (TB) PPDU, the UL TB PPDU at least comprises an ultrahigh throughput (EHT) short training field (EHT-STF), an EHT long training field (EHT-LTF) and payload data; and transmitting the dRU or the dMRU associated with the UL TB PPDU using transmit power control (TPC) such that a symbol associated with the EHT-STF is transmitted at a first power and a symbol associated with the EHT-LTF and the payload is transmitted at a second power. 本发明提供发送资源单元的方法及通信装置，实施本发明实施例可对资源单元进行发送功率控制。本发明提供的一
