Abstract
An operation method of user equipment configured to perform wireless communication with a base station includes receiving a positioning reference signal (PRS) from the base station, calculating a power delay profile (PDP) based on the PRS, detecting at least one path by performing a path search operation based on the PDP, the at least one path including a first path, the path search operation including detecting a first PDP index as the first path, the first PDP index having a value corresponding to a first power of a first threshold PDP or more, and the first threshold PDP being based on a peak power of the PDP, and measuring a reference signal time difference (RSTD) based on the first path.

An operation method of a user equipment configured to perform wireless communication with a base station, the operation method comprising:
- receiving a positioning reference signal (PRS) from the base station;
- calculating a power delay profile (PDP) based on the PRS;
- detecting at least one path by performing a path search operation based on the PDP, the at least one path including a first path, the path search operation including detecting a first PDP index as the first path, the first PDP index having a value corresponding to a first power of a first threshold PDP or more, and the first threshold PDP being based on a peak power of the PDP;
- and
- measuring a reference signal time difference (RSTD) based on the first path.
An operation method of a user equipment configured to perform wireless communication with a base station, the operation method comprising:
- receiving a positioning reference signal (PRS) from the base station;
- calculating a corrected power delay profile (PDP) by removing noise based on the PRS;
- detecting a first PDP index as a first path among at least one path, the first PDP index having a value corresponding to a first power of a first threshold PDP or more, the first threshold PDP being a product of peak power of the PDP and a first ratio, and the first ratio being a real number of 1 or less;
- generating at least one adjusted path by performing a fine-tuning operation based on the at least one path;
- and
- measuring a reference signal time difference (RSTD) based on the at least one adjusted path.
