Abstract: An information transmission method, a base station, and a terminal are disclosed herein. As an example, the method includes selecting, through a base station, one subcarrier spacing from at least one preset subcarrier spacing for transmitting a synchronization signal and a physical broadcast channel according to service delay requirements; configuring a transmitting time number of a beam if the base station uses the beam to transmit the synchronization signal and the physical broadcast channel, the transmitting time number being used to indicate a corresponding transmitting time position of the beam in a pre-stored transmittable time zone for the synchronization signal and the physical broadcast channel; and sending information related to the transmitting time number to a terminal, for the terminal to determine a subframe boundary and complete time domain synchronization according to the information related to the transmitting time number and the pre-stored transmittable time zone.

Abstract: The present disclosure discloses a directional propagation method and apparatus for audio signal, a terminal device and a storage medium. The method comprises acquiring a current location of a target user and audio data corresponding to the target user; propagating audio signal corresponding to said audio data towards said current location in a directional manner. By acquiring a current location of a target user in real time, this technical solution dynamically adjusts the audio data corresponding to the target user to be propagated in a directional manner towards said current location, wherein different audio data types (e.g. Chinese language audio or English language audio) may correspond to different target users, in such a way, it can be realized that different audio signals are propagated in a directional manner towards different locations.

Abstract: The present disclosure provides an allocation method and apparatus for Code Block Groups in a Transport Block. The Method comprises the following steps: sending a Transport Block through a first device to a second device, wherein, the Transport Block comprises at least one Code Block Group which is obtained by the first device allocating the Code Blocks in the Transport Block according to a preset allocation strategy; and sending the preset allocation strategy through the first device to the second device. The technical scheme provided by the present disclosure has an advantage of high efficiency.
