Abstract: This application disclose an encoding method and apparatus, a decoding method and apparatus, a device, a storage medium, and a computer program, and belong to the field of encoding and decoding technologies. In embodiments of this application, a first whitened spectrum for media data is whitened to obtain a second whitened spectrum, and then encoding is performed based on the second whitened spectrum. A spectral amplitude of the second whitened spectrum in a target frequency band is greater than or equal to a spectral amplitude of the first whitened spectrum in the target frequency band. It can be learned that, in this solution, the spectral amplitude of the first whitened spectrum in the target frequency band is increased, so that a difference between statistical average energy of spectral lines for different frequencies in the obtained second whitened spectrum is small.

Abstract: Embodiments provide a data exchange method, a terminal device, and a network device. In accordance with the disclosure, a terminal device can obtain resource information for communicating with another terminal device. The resource information can indicate a time-frequency resource and an antenna port corresponding to an antenna polarization direction. The terminal device can then send scheduling information and data information to the another terminal device using the time-frequency resource and the antenna polarization direction. Time-frequency resources and/or antenna polarization directions used by any two terminal devices to send scheduling information and data information to other terminal devices can be different. In this way, terminal devices using different transmit antenna ports can use a same time-frequency resource, and an optional dimension of resource information is increased, thereby increasing an overall system communication capacity.
