    Abstract: The present disclosure relates to an information transmission method, apparatus, and device, the UE can neither correctly receive a signal from a serving cell nor effectively cancel or suppress interference caused by a signal from a neighboring cell. The information transmission method provided in embodiments of the present application includes: determining, by a network-side device, virtual antenna mapping (VAM) matrix information of at least one cell sending a multiple-input multiple-output (MIMO) signal, and informing user equipment (UE) of the VAM matrix information of the at least one cell. According to the embodiments of the present application, UE may correctly demodulate a MIMO signal received from a serving cell, and may further cancel or suppress interference from a neighboring cell by demodulating a MIMO signal from the neighboring cell.

    Abstract: Embodiments of the present disclosure relate to an environment perception method and a base station. The method includes: sending, by a base station, an electromagnetic perception signal to a to-be-perceived region; receiving electromagnetic feedback signals transmitted, scattered, and reflected from an ambient environment of the to-be-perceived region and an object in the to-be-perceived region; and calculating environment information of the to-be-perceived region based on the electromagnetic feedback signals and the electromagnetic perception signal. In this way, environment information of a coverage area of the base station can be determined. In addition, environment information update frequency may be dynamically adjusted by setting a detection period for sending an electromagnetic perception signal, so as to meet environment information detection requirements of different applications, for example, real-time detection on environment information and high resolution detection on environment information.

    Abstract: Embodiments of this application provide a method and an apparatus for setting a symbol in a communications system that uses a plurality of subcarrier spacings. The method includes: obtaining, by a terminal, a length of a reference blank symbol, where the length of the reference blank symbol is associated with a first subcarrier spacing, and the first subcarrier spacing is a minimum subcarrier spacing in the plurality of subcarrier spacings; and setting, by the terminal based on the length of the reference blank symbol and time domain information of the reference blank symbol, a blank symbol for a subcarrier corresponding to a second subcarrier spacing in the plurality of subcarrier spacings. According to the method and apparatus for setting a symbol provided in the embodiments of this application, when setting, based on the length of the reference symbol, a blank symbol in a subframe corresponding to a subcarrier used by the terminal, the terminal may set one or more complete symbols as blank symbols. This avoids a case in which a symbol cannot work normally because a part of the symbol is set as a blank symbol, thereby improving spectral efficiency of the system.

    Abstract: The present application provides a example signal processing method and a related device. The signal processing method includes, in one implementation, obtaining, in a first cell or sector by a first user equipment (UE), indication information that is borne on a control channel by a base station. The indication information can indicates a cell or sector that sends a service signal to the first cell or sector, and/or a cell or sector that sends an interference signal to the first cell or sector. The first UE can then determine, according to the indication information, at least one of a cell or sector that sends the service signal, as well as or alternatively whether an interference signal exists. When it is determined that an interference signal exists, the first UE can additionally determine a cell or sector that sends the interference signal.
