摘要： An objective of the present invention is to correct a temporal envelope shape of a decoded signal with a small information volume and to reduce perceptible distortions. An audio decoding device which decodes a coded audio signal and outputs an audio signal comprises: a coded series analysis unit that analyzes a coded series which contains the coded audio signal; an audio decoding unit that receives from the coded series analysis unit the coded series which contains the coded audio signal and decodes same, obtaining an audio signal; a temporal envelope shape establishment unit that receives information from the coded series analysis unit and/or the audio decoding unit, and, on the basis of the information, establishes a temporal envelope shape of the decoded audio signal; and a temporal envelope correction unit that, on the basis of the temporal envelope shape which is established with the temporal envelope shape establishment unit, corrects the temporal envelope shape of the decoded audio signal and outputs same.

摘要： A communication device includes: a communication unit configured to transmit or receive a downlink signal or an uplink signal; and a control unit configured to determine a default beam in a wireless communication. In a case where a beam to be applied to the downlink signal or the uplink signal is changed from the default beam, the control unit changes the beam to be applied to the downlink signal or the uplink signal back to the determined default beam.

摘要： In response to a request from a first device (100), a management unit (300) transmits a data encryption key to the first device (100) through a secure environment between the management unit (300) and the first device (100) when integrity of a first application running in an isolated calculation area is verified. The first device (100) encrypts target data using the data encryption key and transmits encrypted target data to a second device (200) through the first application. In response to a request from the second device (200), the management unit (300) transmits a data encryption key to the second device (200) through a secure environment between the management unit (300) and the second device (200) when integrity of a second application running in an isolated calculation area is verified. The second device (200) decrypts the encrypted target data using the data encryption key through the second application.

摘要： A terminal according to one aspect of the present disclosure includes a receiving section that receives a configuration related to repetition of a physical random access channel in a random access procedure, and a control section that determines, on the basis of the configuration, whether to perform repetition of reception or transmission of anything other than the physical random access channel, out of the random access procedure. According to one aspect of the present disclosure, it is possible to improve coverage in a random access procedure.
