name: MASC
full_form: MIMO Average Spherical Coverage
context: The MIMO Average Spherical Coverage (MASC) is the Figure of Merit of FR2 MIMO OTA requirement. FR2 MIMO OTA is measured with 36 constant-density points within the 3D sphere. The MASC is determined by the averaging of the best 18 sensitivity values for power class 3 UE. The averaging shall be done in linear scale for the MASC result according to the formula: Such that {P70,1, â¦, P70,18} are the best 18 sensitivity values from all the 36 constant density measurement points, as defined in Annex B.2.3. The MASC shall be measured at the mid channel as specified in TS 38.508-1 subclause 4.3.1 [7]. The MASC shall be lower than the requirements specified in Clause 7.2. For FR2 MIMO OTA, PRS-EPRE-MAX, i.e., the maximum downlink RS-EPRE supported by the test system, is defined as [-79.1dBm/120kHz]. If the number of test points where the UE can meet 70% maximum throughput outage even under maximum downlink power condition (i.e., [-79.1dBm/120kHz]) is less than [18], then UE fails the test. Other
description: MIMO Average Spherical Coverage (MASC) is a metric used to evaluate the performance of Multiple Input Multiple Output (MIMO) systems in Over-The-Air (OTA) testing, specifically for FR2 (Frequency Range 2). It represents the average sensitivity of a User Equipment (UE) across multiple measurement points within a 3D sphere.
explanation: The text defines MASC as a metric used to evaluate MIMO system performance, and it describes how it is calculated based on user equipment sensitivity across multiple measurement points. This clearly indicates that MASC is a measurement.
