Abstract: Embodiments of this application disclose a communication method and apparatus, to improve positioning accuracy and positioning performance. The method includes: A terminal device receives positioning reference signal configuration information. When the positioning reference signal configuration information includes a physical cell identifier and/or a cell global identifier, if a first condition is met, the terminal device determines that a positioning reference signal corresponding to the positioning reference signal configuration information is from a serving cell.

Abstract: This application discloses a method and a related apparatus for implementing a batch system call. The method includes: loading an executable program to a user-mode virtual address space, where the executable program is obtained by compiling source code of the batch system call, and includes abstract syntax tree AST data of the batch system call; and invoking a first instruction to invoke a kernel to generate, based on the AST data in the user-mode virtual address space, binary code that is used to implement the batch system call. Because there is difficulty in inserting malicious data into such a data structure as the AST, it is difficult to insert malicious code into the binary code of the batch system call, so as to avoid an error or an excessively long delay caused by the malicious code when the kernel runs the binary code of the batch system call, thereby improving security of the batch system call.

Abstract: A signal sending method includes generating M signals. The signal sending method also includes sending the M signals on M time-frequency resource elements. The M signals are in a one-to-one correspondence with the M time-frequency resource elements. At least two of the M time-frequency resource elements overlap in a frequency domain. Any two of the M time-frequency resource elements are free from overlapping in a time domain. M is an integer greater than 1.
