How to simultaneously generate related uplink and downlink channel state

I'd like to study the relationship between the uplink channel and downlink channel in FDD. So I want to generate channel state information(CSI) data. One is from base station(BS) to user equipment(UE) or mobile station(MS), and the other is from UE to BS. THe only difference is their carrier frequency. How can I simultaneously generate the related data?

Hi 秉铜 项

You can refer to the following examples present in MathWorks documentation which generate CSI data by simulating carrier and channel objetcs using "nrCarrierConfig" and "nrCDLChannel" objects and "nrPerfectChannelEstimate" function:

1. NR PDSCG Throughput Using Channel State Information Feedback: https://www.mathworks.com/help/5g/ug/nr-pdsch-throughput-using-csi-feedback.html
2. NR Uplink Channel State Information Estimation using SRS: https://www.mathworks.com/help/5g/ug/nr-uplink-channel-state-information-estimation-using-srs.html

Refer to the following documentation links for more information on creating carrier and channel objects:

1. nrCarrierConfig: https://www.mathworks.com/help/5g/ref/nrcarrierconfig.html
2. nrCDLChannel: https://www.mathworks.com/help/5g/ref/nrcdlchannel-system-object.html
3. nrTDLChannel: https://www.mathworks.com/help/5g/ref/nrtdlchannel-system-object.html
4. nrPerfectChannelEstimate: https://www.mathworks.com/help/5g/ref/nrperfectchannelestimate.html

I hope this answers your query.
