摘要： A method of determining a position in a wireless communication system and apparatus thereof are disclosed. The present invention includes a method for performing, by a user equipment, measurements for observed time difference of arrival, OTDOA, the method comprising: receiving, by the user equipment, system information including information on a reference cell for the OTDOA and information on a neighbor cell for the OTDOA; receiving, by the user equipment, a positioning reference signal, PRS, of the reference and a PRS of the neighbor cell based on the system information; and measuring, by the user equipment, relative timing difference between the neighbor cell and the reference cell based the PRSs, wherein the system information includes a PRS muting sequence for at least one of the reference and neighbor cells, wherein the PRS muting sequence indicates which PRS positioning occasion, among a plurality of PRS positioning occasions, a PRS of a corresponding cell is muted in, wherein each of the plurality of PRS positioning occasions comprises of consecutive subframes to which the PRS of the corresponding cell is allocated, and wherein a first bit of the PRS muting sequence corresponds to a first PRS positioning occasion that starts after a beginning of system frame number = 0 of the reference cell.

摘要： A method and apparatus for determining a positioning measurement interval in a wireless communication system are disclosed. The method includes acquiring a message including Observed Time Difference of Arrival (OTDOA) related data in a higher layer, wherein the OTDOA related data includes a plurality of cell identifiers and Positioning Reference Signal (PRS) configuration information of corresponding cells, transmitting the ODTOA related data to a physical layer from the higher layer, and determining the RSTD measurement interval by the following Equation by using a plurality of cell-specific PRS periods obtained using the PRS configuration information in the physical layer: T
RSTD = T
PRS ⋅(M-1)+ Δ where T
RSTD denotes the length of the RSTD measurement interval, T
PRS denotes the largest of the plurality of cell-specific PRS periods, M denotes the number of PRS positioning occasions, and Δ denotes a measurement time for one PRS positioning occasion.
