Abstract: This application discloses a signal processing method and an apparatus. The method includes: A transmit device generates a PPDU, and sends the PPDU; and a receive device receives the PPDU, and processes M sequences carried in the PPDU. The PPDU shown in this application includes a first field, the first field is used for carrying M sequences, the M sequences correspond to M space-time streams, one sequence corresponds to one space-time stream, and M is a positive integer. According to the method provided in this application, sequence sending efficiency can be effectively improved.

Abstract: This application disclose a method for constructing an indoor map. The method includes: obtaining a plurality of first tracks and a second track, where each first track is a flat-layer track located on an indoor horizontal layer, the second track is a cross-layer track located between different indoor horizontal layers, and a first wireless signal information similarity between each first track point of the first track and each second track point is less than a first threshold; and performing layering on the plurality of first tracks based on a second wireless signal information similarity between the plurality of first tracks, to obtain a layering result, where the layering result may be used to construct an indoor map.
