name: AOA
full_form: Angle of Arrival
context: How many AoA separations are needed to meet the requirement at the same time is the first problem to be solved. A popular option is to verify at least two AoA separations, one from [30Â°, 60Â°, 90Â°] and another one from [120Â°, 150Â°], and the intention is to get a full picture of UE performance. As the simulation results shown in Annex A.8, when AoA separation changes, different UE implementation will show different trends, e.g., For the case that panels in opposite side, UE performance become better when the AoA separation is larger, but when panels in same side, UE performance will be worse with the increase of AoA separation. Due to the different trends, if two different AoA separations need to meet the requirements simultaneously, to accommodate different UE implementation, the requirement for each AoA separation will always be gated by the implementation that has the worst performance. To avoid such restriction, RAN4 agree that only 1AoA separation from all candidates need to be
description: Angle of Arrival (AOA) is a critical parameter in telecommunications, specifically in the context of 5G networks. It refers to the angle at which a signal arrives at a receiver, and its measurement is essential for evaluating UE performance and optimizing network configuration.
explanation: The provided context from 3GPP TS 38.751 highlights AOA as a key parameter in assessing UE implementation and performance. The discussion around AOA separations and their impact on UE performance under different conditions solidifies its classification as a Parameter, given its role in network operation and optimization.
