Nokia试题Senserio： UL Interference TroubleshootingIn wireless network,sometimes we find some uplink interference coming from either interference from BTS or external from uncertain source.(上行干扰 BTS 内部或者外面不确定源)1. pleace calculate Normal Value of PrxNoise. Prxnoise is the noise level in the BTS ,digitalreceiver when there is no load,(thermal noise+noise figure).Thermal noise can be calculated by following formula.Formula: Thermal noise: 10*log10(1000*kTB) where(热噪声) K:1.38E-23T:temperature in Kelvin B:3.84E6Assume T=300Thermal noise: 10*log10(1000*kTB)=10*log10(1000*1.38E-23*300*3.84E6) 2. How impact to the system if interference exists?3. What info element in DT tool can check UL interferecon level? What KPI counter you need tocheck first before on-site visit? 4. After collecting those KPI info,find there is one area having UL interference with 7-？ Cellssuffering UL Interference What is your criteria to choose sites with highly potential interference source finging?5. Now you are ready to find the UL interference what kind of tool andinfo need to preparebefore going for troubleshooting6. When on-site visit ,what BTS unit you need to measure?(answer unit) measurement at BTSunit we will need confirm the the interference in not from BTS orDue to budget limitation there is only 50 she can capansion What KPI or count you propose to evaluate whether this site transmission expanseion cadidateAfter Iub expansion,customer want to improve user experience in HSDPA by purchasing 15 code ,code multiplexing and 16QAM feature ,what parameters setting you need to change according to these features?Because of R99 and HSDPA in share carries ,what is possible negative impact you expactAfter you propose to customer with Dual carriers solution to setors the negative impact,HSDPA user is pushing to 2nd carrier these are two options diretedRRC for HSDPA layer and IFHO to 2nd carrier Please explain the advantage of DiretedRRC for HSDPA layer compared to IFHO to 2nd carrierIn order to verify the 14.4M HSDPA Throughput performance you may need to send DT team to verify ,What info can prove this site is having 14.4Mbps per site with 15code inDT log?If you find the DL application throughput is only 2Mbps what in good RF coverage and quality you may ask RAN engineer to use E2K, tool to help What is the purpose in the E2KWhen DT pass by a building entrance during the Drive test ,the call is drop due to UE camp on Indoor cell in idle mode in front of building entrance and call drop in door cell due to RF signaling fading quicklyNote: This indoor site has 3 sectors ,1st Cell serving B3-B1,2nd Cell serving 1F-3F and 3rd cell serving 4F-6F. All three sectors have samesetting :PtxPrimaryCPICH=33dbm,MaxBitRateDLPSNRT=384bps,MinAllowedBitRateDL=64 bps,InitiaBitRateDL=128kbpsa. Please find a solution for above prolemb. Unfortunately,customer complains that there is high drop call when UE close to windowon 3F,youfind there is other RF signaling from outdoor Please find a solution for this problemc. The other issue is that user working in 4F-6F suffering low DL Throughput even no DLthroughput during the office hour,especially from 10:00AM-13:00P, Below chart show this cell is suffering High code blocking Please propose a short term plan to solve this issue(Parameter Tuning)?and long term plan to solve the capacity issue.Show daily KPI of Code Block Hourly KPI of Code Block 两张图After commercial launch for 2 years ,user traffic keep growing lead to congestion in Iub in order to avoid to this service impact and improve user experience Now operator decide to expansion itansmiision capacity in iub with Hbbrid Back Haul Solution The Hybrid use 1*E1 for R99 RT and NRT service and the others using XDSL with 10M/0Mfor HSDPA service We expact user can get theroatical 14.4Mbps in DL if per site.Cluster TuningNow you are in charage of one cluster tuning Before go for analysis you need to send DT team for drive testing according to the route agreed by customer1. Now you are helping to setup DT tool with 3UE’s Scanner and GPS Please explainfunction or purpose of UE Scanner and GPS during the drive test2. After setup tool you need to setup script for each call pattern you may need toconfig AMR short call AMR long call Packet call FTP Download 128M and scanner a. what is the major testing purpose for AMR short call? What singaling messageindicate call setup successful?b. What is the major testing purpose for AMR Long call ?what signaling messageindicate call successful complete?Please also indicate the dutaill “Cause” of this messagec.
