WebOct 15, 2024 · In my understanding you are confused about why LLR value is scaled by CSI before ULSCH decoding. ulschLLRs = ulschLLRs .* csi; In 5G, due to the use of OFDM, the system model includes a large number of parallel narrowband MIMO cases, one for each OFDM subcarrier. Each of these narrowband channels can have a very different phase … WebHence, we specifically study the impact of different IM methods on 5G NR link adaptation and throughput performance, incorporating both inner loop and outer loop link adaptation …

WebDec 13, 2024 · 5G NR defines the physical resources used for interference measurement as CSI-IM. CSI-IM are zero power CSI-RS, allows the UE to obtain a certain awareness of the interference situation. In the case where the network assumes an interference situation, it may configure ZP-CSI-RS as CSI-IM. Web5G NR RSRQ SS-RSRQ, CSI-RSRQ • SS-RSRQ stands for Secondary synchronization Signal Reference Signal Received Quality. • It is defined as ratio of N x SS-RSRP/NR carrier RSSI.

What is the difference between ZP-CSI-RS and CSI-IM in 5G?
WebHowever, CSI-IM and zero-power CSI-RS serve different purposes. CSI-IM is defined in order to specify a set of resource elements on which a device should measure the interference level while zero-power CSI-RS is defined in order to specify a set of resource elements avoided by the PDSCH mapping. WebIn 5G networks, an intra-system handover is used to transfer a User Equipment (UE), such as a mobile phone, from one Radio Access Network (RAN) to another. A handover may be required for reasons including load balancing, changed radio conditions, or user movement [TS 23.502, Sec. 4.9.1.1]. In other words, when a UE’s WebJohan Sköld, in 4G LTE-Advanced Pro and The Road to 5G (Third Edition), 2016. 13.2.1 Multi-Point Coordination. ... As described in Chapter 9, each such process would correspond to a set of CSI-RS, one for each antenna port, and one CSI-IM resource for interference estimation. In order to support coordinated link adaptation, the set of CSI-RS ... heating system mattress with heating system
