Embodiment Construction

[0037] The subject matter described herein relates to methods, systems and computer readable media for testing radio access network nodes by emulating UEs with different bandwidth and parameter set capabilities in a broadband network. figure 1 is a block diagram and a flowchart illustrating a multi-UE bandwidth and parameter set capability emulator for testing a radio access network node under test. exist figure 1 Among them, a radio access network node testing device 100 includes various components for testing a radio access network node such as a gNB (hereinafter DUT 102). In the illustrated example, the radio access network node testing device 100 includes at least one processor 104 and memory 106 . Multiple UE bandwidth and parameter set capability simulator 108 may be a software component that resides in memory 106 and is executed by processor 104 to test the capabilities of DUT 102 with respect to UEs having different bandwidth and parameter set capabilities. The radio...

Abstract

The subject matter described herein includes methods, systems, and computer readable media for testing radio access network nodes by emulating band-limited RF and numerology-capable UEs in wideband networks. One method includes storing, in a database, UE bandwidth and numerology capability profiles for modeling UEs with different bandwidth and numerology capabilities. The method further includes emulating UEs with different bandwidth and numerology capabilities by communicating, over an uplink interface, the bandwidth and numerology capability profiles to a radio access network node under test. The method further includes receiving, over a downlink interface and from the radio access network node under test, bandwidth part and numerology assignments for emulated UEs. The method further includes validating the UE bandwidth part and numerology assignments.

Description

technical field [0001] The subject matter described herein relates to testing radio access network equipment such as g-nodeBs (gNBs). More specifically, the subject matter described herein relates to emulating a band-limited RF and parameter set capable UE in a broadband network, and using the emulated UE to test radio access network equipment. Background technique [0002] In a broadband network such as a 5G mobile network, an available frequency band for communication extends from 20MHz used in a Long Term Evolution (LTE) network to 400MHz used in a 5G network, which may be aggregated to 800MHz. In order to prevent a UE from having to search and use the entire 400MHz bandwidth to obtain a radio signal from the network intended for said UE, 5G has defined the concept of bandwidth parts (BWP), where each downlink time slot, each The UE is allocated up to 4 bandwidth parts. The bandwidth part defines the frequency range allocated to the UE during each slot. Only one bandwi...
