name: RSTD
full_form: Reference Signal Time Difference
context: This uncertainty contribution originates from the fact that different laboratories may use the two different versions of SAM head: the SAM head phantom or the SAM phantom including the head and the shoulders. Based on the conclusions made in [18] [14] [25] [58], the standard SAM head is the specified phantom. However, the use of the other type of SAM is also allowed with the requirement that the resulting uncertainty contribution is taken into account in the uncertainty budget [48], [49].
description: The Reference Signal Time Difference (RSTD) is a measurement used in differential reporting to compare two downlink RSTD measurements. It represents the difference between the first DL RSTD measurement (RSTD1) and the second DL RSTD measurement (RSTD2), provided that certain conditions are met, such as the absolute value of RSTD2 not being larger than RSTD1. The reporting range for differential reporting RSTD is defined from 0 up to 8191Tc with a resolution step of 2kTc.
explanation: RSTD is classified as a Measurement because it quantifies the difference between two downlink RSTD measurements, as described in the context. The context emphasizes its use in differential reporting and provides details about the conditions and range for its reporting.
