Abstract: This application relates to the field of communication technologies and discloses methods and apparatuses for using an unlicensed spectrum. An example method includes: obtaining information about a target unlicensed frequency band, and transmitting, based on the information about the target unlicensed frequency band, a signal on a supplementary uplink (SUL), where a spectrum of the SUL includes the target unlicensed frequency band. The information about the target unlicensed frequency band includes one or more of the following information: reference signal received power (RSRP), reference signal received quality (RSRQ), and a signal to interference plus noise ratio (SINR).

Abstract: This disclosure provides a decoding method and apparatus in the communications field. The method includes: extracting at least one piece of prior information from at least one first transport block that has been successfully decoded, and assembling the at least one piece of prior information into a prior information set, where one piece of prior information includes header information of a transmission protocol layer of one first transport block; when a to-be-decoded second transport block sent by a transmit end is received, selecting first prior information from the prior information set, where the second transport block is a transport block obtained by the transmit end by coding a third transport block; and decoding the second transport block based on the first prior information and first demodulation information of the second transport block, to obtain the third transport block.

Abstract: A frame rate adjustment method to reduce frame rate jitters in a display process includes: a terminal obtains a computing-access ratio relationship, where the computing-access ratio relationship is used to reflect a ratio between computing tasks and access tasks executed by the terminal; obtains a first working frequency table corresponding to the computing-access ratio relationship, where the first working frequency table includes CPU performance parameters generated when a DDR SDRAM and a CPU work on different working frequency combinations; selects from the first working frequency table based on the CPU performance parameter, a target CPU-DDR SDRAM working frequency combination that meets preset target frame processing duration; and instructs the DDR SDRAM to work on a target DDR SDRAM working frequency in the target CPU-DDR SDRAM working frequency combination, and instructing the CPU to work on a target CPU working frequency in the target CPU-DDR SDRAM working frequency combination.

Abstract: This application provides a transmission method, a terminal device, and a network device. The transmission method includes: sending, by a terminal device, a second message to a network device after receiving a first message that is sent by the network device and that is used to instruct to activate a secondary carrier cell, where the second message is used to indicate a preset time; and receiving, by the terminal device, a third message that is sent by the network device based on the preset time, where the third message is used to instruct to trigger resynchronization of the secondary carrier cell. The transmission method in this application helps quickly reduce a time for triggering resynchronization of an uplink secondary carrier cell, and improve an uplink throughput.
