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.

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.
