Abstract: A phase adjustment method, a related device, and a system, the method comprising obtaining phases and amplitudes of M symbols adjusting a phase of each of the M symbols to an adjusted phase, wherein the adjusting the phase of each of the M symbols to the adjusted phase includes performing at least one of setting the adjusted phase of the first symbol to the phase of the respective symbol, or setting the adjusted phase of a symbol greater than the first symbol according to the phase of the respective symbol and further according to a sum of phases of all symbols whose amplitudes are greater than an amplitude threshold in a group of one or more symbols from a first symbol to an (i−1)th symbol.

Abstract: Embodiments of the present invention discloses a method and a device for allocating a group identifier, which can allocate a non-conflict GID to a non-AP STA in an area covered by multiple BSS networks, so that the problem of GID conflict which is occurred when allocating the GID for the non-AP STA can be reduced. A method provided by the embodiment of the present invention includes: dividing all group identifiers (GIDs) into N parts according to number of the GIDs, and respectively allocating the N parts to N basic service set (BSS) networks, which communicate in a multi user-multiple input multiple output (MU-MIMO) mode, where the N BSS networks have a common area, N is a natural number which is bigger than 1.

Abstract: Embodiments of the present application disclose a modulation method, including: performing coding processing on raw data to obtain a coded sequence; performing constellation mapping on the coded sequence based on a preset constellation diagram, to obtain M symbols; dividing the M symbols into N segments; obtaining a constellation phase of each symbol in the N segments; adjusting a constellation phase of a symbol in each of the N segments according to a preset phase adjustment rule, where the N segments are concurrently adjusted; and modulating M symbols obtained through phase adjustment, to obtain a modulated signal, and sending the modulated signal. Correspondingly, this application further provides a demodulation method, a sending device, a receiving device, and a communications system.
