1. A method, comprising:
receiving, by a user equipment (UE), non-line of sight (NLOS) bias distribution information, wherein the non-line of sight (NLOS) bias distribution information includes at least one statistical parameter associated with representing at least one non-line of sight (NLOS) bias distribution; and
performing, by the user equipment (UE), at least one calculation of at least one position using the non-line of sight (NLOS) bias distribution information,
wherein the method further comprises:
transmitting at least one minimization of drive test (MDT) report that includes non-line of sight (NLOS) bias information, wherein the non-line of sight (NLOS) bias information includes reference signal time difference (RSTD)-related information or time of arrival (TOA)-related measurements.
