Abstract: Embodiments of this application provide a channel state feedback method and apparatus. The method includes: A terminal device receives first indication information from a network device. The terminal device reduces a first value of first information to a second value based on the first indication information. The second value is used to determine channel state feedback information. The first information includes channel state indicator CQI information or signal-to-interference-plus-noise ratio SINR information. The channel state feedback information determined based on the second value is more accurate than channel state feedback information determined based on the first value. This can improve accuracy of the channel state feedback information.

Abstract: This application relates to the field of communication technologies, and discloses an anti-interference electronic device and an anti-interference method. The electronic device includes a first transmission circuit and an anti-interference circuit. The first transmission circuit includes a first receive end, a first transmit end, and a first conversion module. The first conversion module is configured to convert a first-type signal in a signal received by the first receive end into a second-type signal to be sent by the first transmit end. The anti-interference circuit is configured to cancel the second-type signal in the signal received by the first receive end. The cancelled second-type signal is sent by the first transmit end and then received by the first receive end. In the technical solution of this application, the anti-interference circuit is designed in the electronic device to accurately cancel an interference signal in a Wi-Fi link, so that anti-interference can be better implemented when a configured bandwidth of an NR is large. This improves demodulation performance of the Wi-Fi link, and improves communication link quality and user experience.

Abstract: This application provides a media service processing method. An intermediate storage unit is allocated to data of a media service from a server, and storage space of the intermediate storage unit is greater than storage space of a target storage unit, so that longer-duration data of the media service can be buffered in the intermediate storage unit, and the data of the media service is moved from the intermediate storage unit to the target storage unit during play of the media service. This provides a solution to reduce, in a scenario of weak network coverage, a possibility that play of an audio/video app freezes.
