The present application provides a method and a device for encryption of a video stream, a communication equipment, and a storage media. The method for encryption of a video stream includes: acquiring a video stream, encrypting a data part of an I frame by using a first encryption algorithm to obtain a first encrypted data, and encrypting an encryption key of the first encrypted data by using a second encryption algorithm to obtain a second encrypted data, and storing the second encrypted data in a frame header of the I frame to obtain an encrypted I frame.

Method and device for encryption of video stream, communication equipment, and storage medium

Provided in the embodiments of the present disclosure are a wireless communication method, an evolved NodeB and a user equipment, wherein the evolved NodeB receives channel quality of a sub-band sent from the user equipment, the sub-band being a partial bandwidth divided from a system bandwidth, and the evolved NodeB determines a modulation and/or coding scheme adopted by the sub-band, and sends indication information carrying the modulation and/or coding scheme adopted by the sub-band to the user equipment.
