Abstract: This disclosure provides a retransmission method and a communication apparatus, applicable to a wireless or wired communication system. One example method includes: After receiving a signal from a second device, a first device performs first decoding on the signal, then determines whether an error occurs in the signal and a first quantity, and determines, based on a relationship between the first quantity and a first threshold, whether to request the second device to send a first data block, where the first quantity is a quantity of errors that occur in the signal received from the second device, the signal is used to transmit the first data block, and the first threshold is a maximum quantity of errors that can be corrected when the first device decodes the first data block.

Abstract: Embodiments of this application disclose a packet processing method. The method in the embodiments of this application includes: receiving a first negotiation packet from a second network device based on a first interface of a first network device, where the first negotiation packet includes a first source media access control MAC address; determining whether the first source MAC address is the same as a first locked MAC address stored by the first network device, where the first locked MAC address is a MAC address of a network device that is determined by the first network device and that has established negotiation with the first network device; and when it is determined that the first source MAC address is different from the first locked MAC address stored by the first network device, skipping updating a link status of a first link based on the first negotiation packet.

Abstract: A camera module and a mobile terminal including a base, and a lifting camera lens that may slide relative to the base. Protrusion and retraction of the camera lens of the camera module are implemented through sliding between the base and the lifting camera lens. In addition, the camera module further includes a drive apparatus for driving the lifting camera lens to rise or fall. The drive apparatus includes: a rotating cylinder that may rotate relative to the base, where the rotating cylinder is sleeved outside the lifting camera lens and used to drive the lifting camera lens to rise or fall; and a drive mechanism for driving the rotating cylinder to rotate. When the foregoing structure is used, the rotating cylinder is sleeved outside the lifting camera lens, so that the drive apparatus partially overlaps with the lifting camera lens, thereby reducing a size of the camera module.

Abstract: An encoding method, an encoder, and a decoder for dynamic power consumption control are provided. The encoder includes a control unit, an initial encoding unit, and L incremental encoding units. The control unit is configured to enable only the initial encoding unit in an RS (N0, K) operating mode to perform encoding or enable only the initial encoding unit and first j incremental encoding units in the L incremental encoding units in an RS (Nj, K) operating mode to perform encoding. The initial encoding unit is configured to perform RS FEC encoding on m(x) to obtain a quotient D0(x) and a remainder R0(x) of xN0−Km(x) relative to g0(x). An (h+1)th incremental encoding unit is configured to obtain, according to a quotient Dh(x) and a remainder Rh(x), a quotient Dh+1(x) and a remainder Rh+1(x) of xNh+1−Km(x) relative to gh+1(x).
