    Abstract: A photographing method and an electronic device are provided, so that a to-be-photographed target can continue to be tracked after the to-be-photographed target returns to a shooting image, to improve accuracy of focusing performed during photographing of a moving object. The method includes: displaying a first image including a first object and a tracking indicator that is associated with the first object, the tracking indicator indicating that the first object is a tracked target; displaying a second image that does not include the first object or the tracking indicator; displaying a third image including the first object; automatically setting the first object as the tracked target and displaying the tracking indicator associated with the first object; and automatically focusing on the first object when displaying the third image.

    Abstract: A sending device may obtain a first to-be-encoded vector. The sending device may perform first encoding on the first to-be-encoded vector, to obtain a second to-be-encoded vector. The sending device may encode the second to-be-encoded vector based on a first generator matrix, to obtain an encoded codeword. The first generator matrix may include at least N+1 submatrices a, and N of the submatrices a may be located on a main diagonal of the first generator matrix. The first generator matrix may be a block upper triangular matrix, or the first generator matrix may be a block lower triangular matrix. The submatrix a is a polar kernel matrix with a size of 2m*2m, m is a natural number, and N is a natural number. The sending device may send the encoded codeword.

    Abstract: An uplink signal sending and receiving method includes that a first communication apparatus obtains a first timing advance (TA) change rate, and sends an uplink signal in a plurality of first time periods. There is a first time interval between the plurality of first time periods to compensate for a time synchronization drift. A length of the first time interval and a location of the first time interval between the plurality of first time periods are determined based on the first TA change rate, and the first TA change rate is a TA change rate in a communication process of the first communication apparatus.

    Abstract: Embodiments of this application disclose a data transmission method, apparatus, and system, and relate to the communication field. This can flexibly configure a HARQ process to improve a data transmission throughput. A specific solution is: A network device sends a first transport block and a first identifier to a terminal. The first identifier is used to indicate whether to switch, from non-hybrid automatic repeat request HARQ transmission to HARQ transmission, a HARQ process in which the first transport block is located. The first identifier is occupied when the HARQ process uses the HARQ transmission. The terminal receives the first transport block and the first identifier from the network device. The first identifier is used to indicate whether to switch, from the non-hybrid automatic repeat request HARQ transmission to the HARQ transmission, the HARQ process in which the first transport block is located.

    Abstract: Embodiments of this application provide a timing offset parameter update method, a device, and a system, and relate to the field of communication technologies, to help reduce signaling overheads generated when a network device updates a value of a timing offset parameter. The method includes: A terminal device obtains first information that includes a first reference value and first indication information, where the first indication information indicates an update rule of a timing offset parameter, and the first reference value is an initial value of the timing offset parameter. The terminal device updates a value of the timing offset parameter based on the first information and a timing offset variation, to obtain an updated value of the timing offset parameter, where an absolute value of the timing offset variation is equal to an absolute value of a difference between any two consecutively updated values of the timing offset parameter.
