Abstract: This application provides a sound pickup method for a terminal device through a Bluetooth peripheral and a terminal device. The terminal device may pick up sound data through a microphone of the Bluetooth peripheral, and may perform targeted sound effect processing on the sound data picked up by the Bluetooth peripheral by using a preset sound effect DRC parameter corresponding to the Bluetooth peripheral. By using the solution in this application, the terminal device may not only pick up sound through the Bluetooth peripheral, but also perform sound effect processing for different Bluetooth peripherals by using different preset sound effect DRC parameters respectively, to improve the sound effect of the sound picked up through the Bluetooth peripheral, so that a better recording effect can be achieved even if the terminal device is relatively far away from a photographed person or environmental noise surrounding the terminal device is relatively large.

Abstract: The present application relates to a data transmission method, a system, a computer device, and a storage medium. Since a target extension unit is an extension unit connected to a service distal end unit of a matching user equipment set, when data is transmitted between a host unit and a user equipment, data only needs to be transmitted to a service distal end unit group connected to the target extension unit by means of the target extension unit, and data transmission is not needed to be performed with all distal end unit groups, so that a fronthaul bandwidth between the host unit and the extension unit/distal end unit is greatly decreased, thereby reducing design costs of a baseband of the host unit. In addition, the host unit pre-matches the user equipment which can share the same time frequency resource. Therefore, the same time frequency resource only needs to be allocated to the matching user equipment set, which greatly improves the utilization rate of an air interface resource.

The present disclosure provides improved process of creating an instant messaging discussion group, increases creation efficiency, and enhances convenience for a user to use an instant messaging application.

Abstract: Methods and systems for sound propagation and perception for autonomous agents in dynamic environments are described. Adaptive discretization of continuous sound signals allows one to obtain a minimal, yet sufficient sound packet representation (SPR) for human-like perception, and a hierarchical clustering scheme to facilitate approximate perception. Planar sound propagation of discretized sound signals exhibit acoustic properties such as attenuation, reflection, refraction, and diffraction, as well as multiple convoluted sound signals. Agent-based sound perceptions using hierarchical clustering analysis that accommodates natural sound degradation due to audio distortion facilitate approximate human-like perception.
