Many mobiles use a combination of both CSI resources along with PDSCH resources to estimate SINR and then convert it to CQI. Note: CSI-RS SINR > SS-SINR as CSI-RS are lean in structure and can move with PCIĪnother aspect of 5G SINR is based on PDSCH SINR. In RRCIDLE and RRCINACTIVE, the UE can also do cell reselection processes. One way to calculate it is based on CSI-RS/CSI-IM as stated in 3GPP.ĬSI-RS SINR = CSI RSRP / CSI InterferenceĬonvert CSI-RS SINR to CQI and send to gNB An important UE procedure in RRCIDLE is the cell selection procedure. This one can be calculated based on mobile implementation. Since SS_RSRP and SS_SINR is something related to coverage and mobility, 5G needs another SINR for link estimation. Note : SS SINR is used for N310/311 as well However, on different cells, the location of SSS is same so all the SSS will interfere with each other and thus SS SINR would be low. So, SS_RSRP and SS_SINR are important values. Therefore, the interference between them is reduced.įor 5G, UE measures coverage based on SSS in SSB. For different cells, the RS move in frequency domain based on PCI. Outputs : RSRP (dBm) = -106.78 dBm RSRQ (dBm) = -10.In LTE, the Cell Reference Signals are used for both coverage and link estimation.RSSI is measured over entire bandwidth of occupied RBs (Resource Blocks).Also the UE capability exchange isnt happening for 5G. ![]() However, after the attach the network doesnt seem to continue with any 5G activation. But your console log seems ok, you get an IP. RSRQ is the Reference Signal Received Quality I am afraid the TDD support for LTE in srsUE hasnt been a focus for some time so there might be issues with this in the first place.RSRP is the Reference Signal Received Power and is measured in a single RE of the LTE REsource Block. Hence, RSRP is also called as average received power of a single reference signal RE (Resource Element).The formulas used in within the calculator is below, where: The calculation is performed based on RSSI and channel Bandwidth considered. In this page we present a simple LTE RSRP & RSRQ calculator. ![]()
