[{"name":"R5-202459","title":"On the SNR for FR2 TRx test cases","source":"ROHDE & SCHWARZ","contact":"Edwin Menzel","contact-id":65839,"tdoctype":"discussion","for":"Endorsement","abstract":"At RAN5 #86, estimations for the SNR and relaxations of core requirements have been discus-sed [1 \u2013 7]. In this document, we present the results of our analysis based on the common assumptions for the not yet decided figures.\nDiscussion\nA detailed description of the total SNRtotal based on the measurement of total component power for both polarizations can be found in reference [6]. \nIn Table 1, we present our results for SNRtotal under the assumption that the UE is allowed to transmit a maximum peak EIRP of 43 dBm. \nFor ACLR we provide the same numbers as in the previous meeting but note that the general case can be derived by \nSNR = SNRtable + (6.5 dB \u2013 MPR) + ?CHBW + ?ArrayMetric\nThe values in the table SNRtable are for assumption 1, i.e., 8x2 antenna array and TRP metric, an MPR of 6.5 dB , and 400 MHz channel bandwidth. MPR is the worst MPR of the chosen test points, and ?CHBW = 10log10(400MHz\/CHBW). ?ArrayMetric is 0 dB for 8x2 antenna array and TRP metric (ACLR Assumption 1). ?ArrayMetric is 6 dB for 1x4 antenna array and TRP metric (ACLR Assumption 2). For EIRP metric, ?ArrayMetric is 16 dB and is independent from the directivity of the antenna array. \nThe MPR depends on waveform, modulation and RB allocation. For the currently defined test points the highest MPR occurs for 400 MHz channel bandwidth and 64QAM DFT-s-OFDM with a value of 6.5 dB. It is noted that the MU and SNR analysis has to be updated once CP-OFDM 64QAM were applied as test point for ACLR.\nIn summary, SNR estimations for low PSD test cases have been provided and the influence of noise has been analyzed.\nProposal 1: Apply the SNR values in Table 1 and Table 2 as basis for determining the relaxation amount and for specifying the MU impact due to noise for the TT analysis.","secretary_remarks":"","agenda_item_sort_order":89,"ainumber":"5.3.2.17","ainame":"\tDiscussion Papers \/ Work Plan \/ TC lists","tdoc_agenda_sort_order":24590,"status":"noted","reservation_date":"2020-05-08 20:26:22","uploaded":"2020-05-09 08:59:07","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":[{"winame":"5GS_NR_LTE-UEConTest"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_87_Electronic\/Docs\/R5-202459.zip","group":"R5","meeting":"R5-ah-38102","year":2020,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
