Abstract: This application provides a biological sequence data processing method including selecting a target base from bases in a biological sequence fastq file according to characteristic information of each base. A base patch file is generated by using characteristic information of the target base. Lossless compression is performed on the biological sequence fastq file to obtain a compressed fastq file, and lossless compression is performed on the base patch file to obtain a compressed patch file. The compressed patch file and the compressed fastq file are decompressed. In response to determining that characteristic information of the target base in the decompressed compressed patch file is inconsistent with characteristic information of the target base in the decompressed compressed fastq file, the characteristic information of the target base in the decompressed compressed fastq file is modified to the characteristic information of the target base in the decompressed compressed patch file.

Abstract: In a time deviation determining method, a terminal determines an uplink timing advance between the terminal and a base station; determines a one-way transmission delay based on the uplink timing advance; and determines a clock time deviation between the terminal and the base station based on the one-way transmission delay, a time difference between a base-station clock time of a system frame in two system frames and a terminal clock time of a following system frame in the two system frames, and a time difference between the two system frames. In the solution provided in this application, the clock deviation between the terminal and the base station can be determined more flexibly and accurately. In addition, signaling interaction between the terminal and the base station is reduced, and network resources are saved.

Abstract: This application relates to the field of wireless communications, and in particular, to a resource scheduling technology for vehicle to vehicle communication in a wireless communications system. In a resource scheduling method, a first terminal device receives a second-vehicle message sent by at least one second terminal device, where the second-vehicle message carries vehicle status information of the second terminal device. The first terminal device determines a historical resource occupation status of the at least one second terminal device, and selects, based on the vehicle status information indicating a vehicle location and a traveling status of the second terminal device, a first resource used for sending a first-vehicle message.
