  • Method and apparatus for transmitting location estimation message in wireless communication system
    Patent number: 9736629
    Abstract: Provided are a method and an apparatus for transmitting a message through a terminal in a wireless communication system. The terminal receives positioning reference signals (PRS) from a reference cell and at least one of the neighbor cells, receives an auxiliary data provision message including a reference cell PRS muting sequence for indicating a muting pattern of the PRS transmitted through the reference cell and a neighbor cell PRS muting sequence for indicating the muting pattern of the PRS transmitted through at least one of the neighbor cells from an enhanced serving mobile location center (E-SMLC), and transmits a reference signal time difference (RSTD) measured on the basis of the PRS received from the reference cell and the at least one of the neighbor cells to the E-SMLC.
    Type: Grant
    Filed: June 26, 2015
    Date of Patent: August 15, 2017
    Assignee: LG Electronics Inc.
    Inventors: Kyung Soo Woo, Su Hwan Lim, Chi Jun Ahn, Dae Won Lee, Suk Hyon Yoon, Seung Hee Han
