Abstract

Systems and methods for a scalable test model for a cellular communications system having multiple different bandwidth and subcarrier combinations are disclosed. Embodiments of a method performed by atest node and corresponding embodiments of a test node are disclosed. In some embodiments, a method performed by a test node comprises generating a test signal for a particular bandwidth and subcarrier spacing combination, the test signal being in accordance with a test model that is scalable for a plurality of different bandwidth and subcarrier spacing combinations. By using the scalable test model, the test model can be flexibly used to test for different bandwidth and subcarrier spacing combinations.

Description

[0001] related application [0002] This application claims the benefit of Provisional Patent Application Serial No. 62 / 683,471, filed June 11, 2018, and Provisional Patent Application Serial No. 62 / 689,571, filed June 25, 2018, the entire disclosures of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to conformance testing for cellular communication systems, and in particular, to scalable test models for cellular communication systems for different bandwidth and subcarrier spacing combinations. Background technique [0004] New radio (NR) has introduced new aspects in mobile communications, one of which is the addition of multiple different subcarrier spacings (SCS) and A new bandwidth has been added at the 28GHz frequency band (FR2). The purpose of the different SCSs is to provide flexibility in supporting new applications such as ultra-reliable and low-latency communications (URLLC) and the Internet of Things (IoT), and...
