METHODS OF DATA UNIT TRANSMISSION: PHYSICAL LAYER PROTOCOL, CHIP, COMMUNICATION DEVICE, AND READABLE STORAGE MEDIA

Abstract

This refers to the method of transmitting physical layer protocol data units (PPDUs), chips, communication devices, and storage media. The access point (FP) sends an activation frame to activate at least one station (STA) to transmit the uplink PPDU. After receiving the activation frame, at least one STA transmits the corresponding uplink PPDU. This uplink PPDU includes data fields and long training fields (LTFs). The data fields are carried on the allocated resource unit (RU). The LTFs are carried on all subcarriers in the first transmission bandwidth. The first transmission bandwidth is the bandwidth occupied by the allocated RU that is allocated by the AP to at least one STA for transmitting the uplink PPDU.Alternatively, the LTFs are carried on all subcarriers of the RUs continuously corresponding to the distributed RU. According to the above solution, this can ensure that the average power of the data sent by the AP is increased, and the peak-average power ratio (PAPR) of the LTFs can also be ensured, thereby ensuring system efficiency.
