Keysight Gains Validation for First 3GPP Release 16 16/32 Transmitter Performance Enhancement Test Cases

- Validations cover single and multiple precoding matrix
indicator test cases for 16 and 32 element transmitters operating
on the frequency-division duplexing and time-division duplexing
bands
- First test cases for 3GPP Release 17 Enhanced Power Saving
covering reductions in network paging and the increase of RedCap
device discontinuous reception cycles validated
- Validation achieved at Conformance Agreement Group #77 meeting
hosted by Keysight in Malaga, Spain
Keysight Technologies, Inc. (NYSE: KEYS) gained approval for the
industry’s first 3GPP Release 16 (Rel-16) 5G New Radio (NR) single
and multiple precoding matrix indicator (PMI) test cases for 16 and
32 element transmitters operating on the frequency-division
duplexing (FDD) and time-division duplexing (TDD) bands. The
validated test cases, which are for use with Keysight's 5G network
emulation conformance test platform (TP168), were obtained at the
Conformance Agreement Group (CAG) #77 meeting of the Global
Certification Forum (GCF) hosted by Keysight in Malaga, Spain
during January.
Networks based on 5G NR standards support multi-antenna
technologies known as MIMO, which improve spectral efficiency and
enhance communication. To implement multi-antenna systems, enhanced
precoding techniques are applied to the transmitter to map data
into the different transmit antennas. The optimal precoding depends
on a PMI Codebook value reported by the device, which makes the
choice from several precoding options based on its own channel
measurements.
As part of Rel-16, the 3GPP added new test cases to validate
device performance in multi-antenna systems. Keysight S8705A RF/RRM
test solution is the first to gain validation for these new tests,
which require unprecedented fading resources to emulate 16 and 32
transmitter connections to use equipment (UE) with 2 and 4
receivers.
Keysight also achieved the following achievements supporting
Release 17 (Rel-17) Enhanced Power Saving and RedCap features:
- Validation of test cases verifying UE support of a function
that reduces the number of times a device interacts with the
network, in order to extend the battery life of devices using the
S8705A RF/RRM test solution.
- Validation of test cases ensuring RedCap devices support the
Rel-17 increase in the extended discontinuous reception (eDRX)
cycle, which is the duration of time a device is in sleep mode in
order to extend battery life. This was completed with the Keysight
S8704A Protocol Conformance Toolset and activates the RedCap Rel-17
eDRX GCF work item.
Muthu Kumaran, General Manager of Keysight's Device
Acceptance Solutions, said: "Enhancing connection performance
is a priority for network operators to deliver a better quality of
service to final users. Multi-antenna systems are possible with NR
and now the first approved tests are brought into the market by
Keysight to ensure device’s performance is thoroughly tested.
Additionally, validations supporting Rel-17 Enhanced Power Saving
features are crucial to drive advancements in 5G NR Rel-17 for
commercial 5G NR and RedCap devices market introduction."
