AI Technical Summary
Technical Problem
How to increase the transmission power of a station to achieve higher gain without increasing the power spectral density?
Method used
By allocating 60MHz discrete bandwidth Distributed Resource Units (DRUs) to the site and specifying the design rules for which subcarriers and pilot subcarriers are included in the DRU, the transmit power is increased while meeting the power spectral density requirements. The indication method of conventional resource units (rRUs) is reused to reduce implementation complexity.
Benefits of technology
Without increasing the power spectral density, the transmission power of the station is increased, the gain is increased, and the complexity and implementation difficulty of the channel smoothing algorithm are reduced.

Abstract
The application discloses a communication method and device. The method is suitable for 802.11 series standard protocols, for example, but not limited to, 802.11a / b / g, 802.11n, 802.11ac, 802.11ax, 802.11be and 802.11bn, etc. The method comprises the following steps: receiving a trigger frame, the trigger frame is used to indicate a DRU allocated to a station; and transmitting a PPDU on the allocated DRU according to the trigger frame; wherein the discrete bandwidth of the allocated DRU is 60 MHz. In the method, the access point allocates a DRU with a discrete bandwidth of 60 MHz to the station, and the station transmits a PPDU based on the DRU with a discrete bandwidth of 60 MHz, so that the transmission power of the station can be improved to obtain higher gain without increasing the power spectrum density.
