STEPS & PROCEDURES FOR ACHEIVING 21mbps Hsdpa throughput STEPS & PROCEDURES FOR ACHEIVING 21mbps Hsdpa throughput:
#64QAM -21Mbps – RF ENVIRONMENT
Attained bit rate will depend on the radio conditions
64QAM requires good Signal-to-interference ratio as mentioned below
NO of Codes : 15 15 15 15Modulation 64QAM 64QAM 64QAM 64QAM
CQI 28 to 30 23 to 25 21 to 23 <21
#L1 bit rate 21 Mbps 18 Mbps 16 Mbps 14 Mbps
›HSDPA 21 Mbps at one carrier only can be achieved by having the following SW features.
–FAJ1211328 R1, Enhanced Layer2 (W10)
–FAJ1211331 R1, HSDPA 64 QAM (W10)
›EUL to 1.166 Mbps
›EUL throughput of 1.166 Mbps should be obtained in relation to the below mentioned license.
- FAJ1211317 R2, Enhanced Uplink 2ms TTI, Node (W10)
# BASIC Requirements
›Achieving the above mentioned scopes need supporting hardware and software.
›All the needed hardware and software are briefed in the following slides.
›Performing this test also needs a 21Mbps capable modem.
›ZTE MF662, 21Mbps HSPA modem has been used.
#RNC REQUIREMENT
RNC Hardware
–ET- IPG Board
RNC Software
All the RNCs assumed to handle the Iu_PS user plane and the signaling SS7 on IP
›
–FAJ121973 R1, SS7 over IP
–FAJ121976 R1, Iu-PS user plane over IP
# NODE B REQUIREMENTS
Node - B Hardware
–DUW IP interface
–Need to check for Other Desired HW as well
Node - B Software
All the RNCs assumed to handle the Iu_PS user plane and the signaling SS7 on IP
›
–FAJ1211132 R2, Iub over IP/Ethernet in RBS, Node (P7)
–FAJ1211155 R1, Network Synch Client for IP transport, Node (P7)
To be continued .....
