Abstract

The present application relates to the field of communications technologies, and in particular, to a communications method and apparatus. The application can be applied to IEEE 802.11ax standard, 802.11be standard, 802.11bn standard and the like, and other standards of IEEE 802.11 series, such as 802.15 standard, 802.11bf standard or IMMW standard or star flash standard and the like. The application designs an LTF sequence suitable for DRU, which can have lower PAPR under different DRU transmission.

Description

Communication method and device Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and apparatus. Background Wireless local area networks (wireless local area network, WLAN) have evolved to date over multiple generations of standards including 802.11a/b/g, 802.11n, 802.11ac, 802.11ax, 802.11be, and 802.11bn, among others. Among them, the 802.11n standard is called High Throughput (HT), the 802.11ac standard is called very high throughput (very high throughput, VHT), the 802.11ax standard is called high efficiency (HIGH EFFICIENT, HE), the 802.11be standard is called ultra high throughput (extremely high throughput, EHT), and the 802.11bn can be called ultra high reliability (ultra high reliability, UHR). At present, a communication mode with low power consumption (LPI) in a room is defined, and the maximum power and the maximum frequency spectrum density of the transmission are strictly limited. Illustratively, for an Access Point (AP), the maximum power may be 36dBm and the maximum power spectral density may be 5dBm/MHz. For Stations (STAs), the maximum power may be 24dBm and the maximum power spectral density may be-1 dBm/MHz. The transmit power of the device is limited by both the maximum power and the maximum power spectral density, and first the transmit power cannot exceed the maximum power and the transmit power spectral density cannot exceed the maximum power spectral density. The maximum power spectral density is more severely limited than the maximum power, and the maximum power allowed to be transmitted is typically more limited by the maximum power spectral density. For a station, the maximum power limit specified by the regulations is only reached when the bandwidth is 320MHz maximum. Below this bandwidth, signals can only be transmitted with lower power, all because of the limitation of the maximum power spectral density. Due to the limited power spectral density, the number of limited subcarriers is scattered to a wider bandwidth, i.e. more subcarriers, so that the transmission power can be improved, i.e. a discrete resource unit (distributed resource unit, DRU) or a distributed RU is obtained. Long training fields (longtrainingfield, LTFs) (hereinafter may be referred to as LTF fields) are used for channel estimation, which are generated based on long training sequences (hereinafter may be referred to as LTF sequences), the current LTF sequences being designed for regular RU (rRU). Designing LTF sequences under DRUs is therefore highly desirable. Disclosure of Invention The embodiment of the application provides a communication method and a communication device, which effectively reduce the peak-to-average power ratio (peak to average power ratio, PAPR) of an LTF sequence on a DRU. In a first aspect, an embodiment of the present application provides a communication method, where the method may be applied to a first station, where the first station may include a wireless local area network (wireless local area network, WLAN) device (including a Wi-Fi device or a device involved in a star-flash alliance, etc.), or a chip, a functional module, a processing system, a communication component, etc. that may be disposed in the WLAN device. The method comprises the following steps: Generating a long training field according to a long training sequence, and transmitting the long training field, wherein the sequence value corresponding to 484-tone DRU in the long training sequence is any one of the following: [-1 1 1 1 1 -1 -1 -1 1 1 1 1 -1 -1 -1 -1 -1 1 -1 1 -1 -1 -1 1 -1 1 1 -1 1 1 -1 1 1 -1 1 1 -1 1 -1 -1 1 1-1 -1 -1 -1 1 1 1 1 -1 -1 1 1 -1 -1 1 -1 -1 1 1 1 1 1 1 -1 1 1 1 -1 -1 1 -1 -1 1 -1 1 -1 1 1 -1 1 1 -1 1 -1-1 -1 -1 -1 -1 -1 1 -1 -1 -1 -1 1 -1 -1 -1 1 -1 1 -1 1 1 -1 -1 1 1 1 -1 -1 -1 1 1 1 -1 1 1 1 1 -1 -1 -1 -1 -1 1 -1 -1 -1 1 -1 1 1 -1 1 -1 1 -1 -1 -1 -1 1 1 1 -1 1 1 -1 1 -1 1 1 -1 -1 -1 -1 -1 -1 -1 1 1 1 1 1 1 1 -1 1 -1 1 -1 -1 -1 1 1 -1 -1 -1 1 1 1 -1 1 -1 -1 1 1 1 1 -1 1 -1 1 1 1 1 -1 1 1 1 1 1 1 1 -1 1 -1 1 -1 -1 1 1 -1 1 1 1 -1 1 1 1 -1 1 1 -1 1 1 1 1 -1 1 -1 -1 -1 1 -1 -1 -1 -1 1 1 1 -1 -1 1 -1 1 1 -1 1 1 -1 1 -1 1 -1 -1 -1 -1 1 1 1 -1 -1 1 -1 -1 -1 -1 1 -1 1 1 1 1 -1 -1 -1 -1 -1 -1 1 1 1 1 1 1 1 -1 -1 1 -1 1 1 -1 -1 1 -1 1 -1 1 -1 1 -1 -1 -1 1 1 1 -1 1 1 -1 1 -1 1 -1 -1 1 1 -1 -1 1 1 -1 -1 1 1 -1 -1 1 1 -1 1 -1 -1 -1 1 -1 1 -1 1 1 -1 -1 -1 1 -11 1 1 -1 -1 1 -1 1 -1 -1 1 1 -1 -1 1 1 1 -1 -1 -1 -1 1 -1 -1 -1 -1 1 1 1 1 1 1 1 1 -1 -1 -1 1 -1 1 1 -1 1 1 -1 -1 -1 -1 -1 1 -1 -1 1 -1 -1 1 1 -1 -1 1 1 1 1 1 -1 1 1 -1 -1 1 1 -1 1 1 -1 -1 1 1 1 -1 1 1 -1 1 -1 1 -1 -1 1 1 -1 1 1 -1 1 1 -1 1 -1 1 1 1 1 1 1 1 -1 -1 1 1 1 -1 -1 1 -1 1 1 -1 1 1 -1 -1 1 1 1 1 1 -1 1 -1 -1 -1 11]; [-1 -1 1 -1 1 1 -1 1 1 -1 1 -1 -1 1 -1 1 -1 -1 -1 -1 -1 1 -1 -1 -1 -1 1 1 1 -1 -1 -1 1 1 1 -1 -1 -1 -1 1 1 -1 -1 1 -1 1 1 -1 1 -1 -1 1 1 -1 -1 1 1 1 -1 -1 1 -1 1 -1 1 1 1 -1 1 1 -1 -1 -1 1 1 1 1 1 1 -1 -1 -1 1 1 1 1 -1 1 -1 1 -1 1 1 1 -1
