Abstract: The present invention discloses a bandwidth adjustment method and a related device, so as to flexibly adjust a bandwidth. A controller obtains behavior characteristic statistics sent by an end cloud node device, and obtains bandwidth resources remaining on a system. The behavior characteristic statistics are a statistical result indicating behavior characteristics of occupying network bandwidth resources by a user when accessing the end cloud node device. The controller determines a bandwidth adjustment amount of the end cloud node device according to the behavior characteristic statistics and bandwidth remaining on the system. The controller sends a bandwidth adjustment instruction to a first network device. The bandwidth adjustment instruction is used to instruct the first network device to adjust, according to the bandwidth adjustment amount, a bandwidth allocated to the end cloud node device by a network device on a transmission link.

Abstract: When receiving a first data frame sent by a transmitting apparatus, a receiving apparatus may return error indication information including an identifier of at least one erroneous codeword group to the transmitting apparatus if it is found that an error occurs in an initial codeword of the first data frame. The transmitting apparatus may obtain the erroneous codeword group and encode the erroneous codeword group, and retransmit a part of a sub check codeword obtained through encoding to the receiving apparatus. The receiving apparatus may obtain a third check matrix based on a first check matrix, a second check matrix, and a location of the at least one erroneous codeword group in the initial codeword, and re-decode the retransmitted partial sub check codeword and content of the first data frame together based on the third check matrix, so as to obtain a correct initial codeword.

Abstract: Embodiments of this application provide example permission negotiation methods and apparatuses during communication, and electronic devices. An example first electronic device displays an interface of a currently running communication application, and obtains, in response to the first operation, a permission item restricted for use in a process of communication with a second electronic device. Then, the first electronic device sends a first request to the second electronic device that includes the permission item restricted for use. The first electronic device receives confirmation information of the second electronic device for the permission item restricted for use, and restricts, based on the confirmation information, a locally installed application on applying for the permission item restricted for use. After communication with the second electronic device ends, the first electronic device restores settings of the permission item of the locally installed application to settings preceding the communication with the second electronic device.
