摘要： An audio encoding method and apparatus and an audio decoding method and apparatus are disclosed. During encoding of an audio channel signal of a current frame, whether a first target virtual loudspeaker and a second target virtual loudspeaker corresponding to an audio channel signal of a previous frame of the current frame meet a specified condition is first determined. When the first target virtual loudspeaker and the second target virtual loudspeaker meet the specified condition, a first encoding parameter of the audio channel signal of the current frame is determined based on a second encoding parameter of the audio channel signal of the previous frame, so that the audio channel signal of the current frame is encoded based on the first encoding parameter to obtain an encoding result, and the encoding result is written into a bitstream.

摘要： A method for obtaining a higher-order ambisonics (HOA) coefficient includes obtaining location information of a virtual speaker on a preset spherical surface, where the preset spherical surface includes M circles of longitude and N circles of latitude, and obtaining, based on the location information and a preset reference trigonometric function table, a trigonometric function value corresponding to the location information, where the reference trigonometric function table includes an elevation trigonometric function table and/or an azimuth trigonometric function table, and obtaining an HOA coefficient for the virtual speaker based on the trigonometric function value corresponding to the location information.

摘要： A communication method and a terminal device are provided. The communication method includes: receiving, by a network device of a first communications standard, a suspension notification message sent by a terminal device, where the suspension notification message is used to notify that the terminal device is to leave a network of the first communications standard to listen to a network of a second communications standard, the network of the first communications standard carries data services, and the network of the second communications standard carries voice services; and suspending, by the network device according to the suspension notification message, sending scheduling information to the terminal device, and suspending detecting measurement information sent by the terminal device. The communication method, the network device, and the terminal device that are provided in the present disclosure can be used to save scheduling resources and avoid detection of an incorrect measurement quantity.
