Abstract: A method of decoding of a video or picture bitstream implemented by a decoding device, the bitstream including a current sequence parameter set (SPS) comprising syntax elements that apply to a video sequence, the method comprising: obtaining a first syntax element used to determine a maximum number of temporal sublayers that is allowed to be present in each coded layer video sequence) referring to the current SPS, wherein a value of the first syntax element is in a range of 0 to a first value, wherein the first value is a value of a second syntax element used to determine the maximum number of temporal sublayers that is allowed to present in a layer in each coded video sequence referring to a video parameter set, when the second syntax element is referred to by the SPS; decoding the bitstream based on the value of the first syntax element.

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 heat dissipation apparatus, a connection structure, and an electronic device. A first heat sink is in thermal contact with a first heat-generating device on a first component, and a second heat sink is in thermal contact with a second heat-generating device on a second component. The first heat sink and the second heat sink are communicated through a pipeline (120), and the three are filled with a cooling medium. Heat generated by either of the first heat-generating device and the second heat-generating device may be transferred to the cooling medium in the heat sink through the corresponding heat sink, and the heat is dissipated outward through a surface of the heat sink.

Abstract: A mobility management method and an apparatus can improve continuity of a multicast service of a terminal device. The method includes: A source access network device sends, to a target access network device, a first message for requesting to hand over a first multicast service of a first terminal device to a first target cell, and the target access network device sends a second message to the source access network device as a response to the first message, where the second message includes first information indicating a first candidate cell, and the first candidate cell is a cell that provides a multicast service for a terminal device in an RRC non-connected mode. After receiving the second message, the source access network device sends, to the first terminal device, third information indicating a second candidate cell.

Abstract: A power control method. The method includes: a communication apparatus determines a target forwarding power based on a first forwarding power, a second forwarding power, and a third forwarding power, and forwards, by using the target forwarding power, a first signal received from a first device to a second device. The target forwarding power is a lowest power of the first forwarding power, the second forwarding power, and the third forwarding power. The first forwarding power is determined based on an indication of a network device, the second forwarding power is related to an input power of the communication apparatus and a forwarding gain of the communication apparatus, and the third forwarding power is determined based on a maximum forwarding power limit of the communication apparatus.

Abstract: A communication method and apparatus are provided. A session management function network element receives first information from an edge application server discovery function network element, where the first information comprises internet protocol (IP) address information of N edge application servers (EASs), and N is an integer greater than or equal to 2. The session management function network element determines an EAS IP address information set based on the IP address information of the N EASs, where the EAS IP address information set comprises IP address information of M EASs, the IP address information of the M EASs corresponds to a same data network access identifier (DNAI), and M is an integer less than or equal to N. The session management function network element sends the EAS IP address information set to the edge application server discovery function network element.
