Abstract: A signal processing method and device includes obtaining spectral coefficients of a current frame of an audio signal, in which N sub-bands of the current frame comprises at least one of the spectral coefficients. A total energy of M successive sub-bands of the N sub-bands, a total energy of K successive sub-bands of the N sub-bands, and an energy of a first sub-band are obtained to determine whether to modify original envelope values of the M sub-bands. When the original envelope values of the M sub-bands are modified, encoding bits are allocated to each of the N sub-bands according to the modified envelope values of the M sub-bands.

Abstract: A side information transmission method and apparatus, where data to be transmitted by a transmit end includes at least one first data sub-block and at least one second data sub-block. A first modulated signal is obtained based on a first phase rotation factor. A second modulated signal is obtained based on a second phase rotation factor. Side information is generated based on the first phase rotation factor and the second phase rotation factor. The first data sub-block is carried on a first subcarrier, and the side information is also mapped to the first carrier. The first modulated signal corresponding to the at least one first data sub-block, the second modulated signal corresponding to the at least one second data sub-block, and a modulated signal corresponding to the side information are superposed to obtain a to-be-transmitted signal.

Abstract: Embodiments of this disclosure provide a power adjustment method, apparatus, and system. A first access network device may obtain a power back-off value at a first moment, and compare the power back-off value at the first moment with a power back-off value at a second moment. The second moment is earlier than the first moment. When a difference between the power back-off value at the second moment and the power back-off value at the first moment is greater than or equal to a first threshold, the first access network device adjusts an output power based on the power back-off value at the first moment.

Abstract: A packet loss processing method and a network device are provided. The method includes: A first node obtains a first forwarding label of a first packet, where the first packet is a discarded packet. The first node determines, based on the first forwarding label, that the first node does not have a LSP corresponding to the first forwarding label. The first node sends a first message to a second node, where the first message includes the first forwarding label, and the first message is used to indicate that the first node does not have the LSP corresponding to the first forwarding label. The second node may be, for example, a peer node of the first node. The first node sends the message to the peer node, to indicate that the first node does not have the LSP corresponding to the forwarding label.

Abstract: User equipment receives at least one TAC that is broadcast by a network device, where the TAC includes geographical location information, and the geographical location information is used to indicate a geographical location of a preset location point in a TA corresponding to the TAC. The user equipment determines, based on the TAC and a tracking area list (TAL), whether the TAL needs to be updated. If it is determined that the TAL needs to be updated, the user equipment sends a tracking area update request to the network device. The user equipment receives a response message, of the tracking area update request, returned by the network device.

Abstract: In an audio signal processing method, an audio signal processing apparatus receives an audio signal that meets a screening condition at a listening position, where the screening condition includes one or more of the following conditions: a volume at the listening position being greater than or equal to a volume threshold, a listening distance between the sound source and the listening position being less than or equal to a preset listening distance, or the sound source being in a range corresponding to a listening orientation. The apparatus decodes the audio signal meeting the screening condition to obtain a decoded audio signal. The apparatus then renders the decoded signal based on a sound channel transfer function in a playing device to obtain an output signal.
