1. A method implemented by a receiving device (RD), the method comprising:
receiving, by the RD, a configuration for a first reference signal comprising symbols, wherein the first reference signal is configured for transmission by a transmitting device (TD) using a first subcarrier spacing, wherein the symbols of the first reference signal transmitted by the TD are each repeated an integer number of times, wherein the integer number is equal to a ratio of a second subcarrier spacing to the first subcarrier spacing, wherein the second subcarrier spacing is different than the first subcarrier spacing, and
wherein the symbols of the first reference signal include a first symbol repeated the integer number of times followed by a second symbol repeated the integer number of times based on the ratio of the second subcarrier spacing to the first subcarrier spacing; and
receiving, by the RD, the first reference signal using the second subcarrier spacing.
