Abstract: A data query method and apparatus are disclosed. The method includes: determining a target directory block including m directory entries and m file names, where the m directory entries one-to-one correspond to the m file names, and the m directory entries and the m file names are sequentially arranged according to a preset rule; determining a current first set and a current second set based on a binary search algorithm and the target directory block; determining a first common prefix between a to-be-accessed file name and a file name in the current second set; comparing the to-be-accessed file name with a third file name character by character from a first character after the first common prefix; and if the to-be-accessed file name is the same as the third file name, obtaining data of a to-be-accessed file based on a directory entry corresponding to the third file name.

Abstract: This application provides sounding reference signal transmission methods and apparatuses. One method comprises: determining, by a terminal device, that a sounding reference signal (SRS) to be transmitted is an nSRSth transmission of a plurality of SRSβtransmissions, wherein nSRS is a non-negative integer; selecting, by a terminal device, an antenna group of Λ antenna groups to transmit the sounding reference signal (SRS) based on Λ and nSRS, such that when sending the SRS for 2Λ times, the SRS is sent through each of the Λ antenna groups at least once, wherein Λ is a positive integer greater than or equal to 3; and sending, by the terminal device during the nSRSth transmission, the SRS through antenna ports comprised in the selected antenna group.
