The evaluation for UL impact for M-MIMO DL Tput (1/2)
Purpose
-
Investigate the TCP ACK delay for Massive MIMO DL Tput when there is UL traffic
System level simulation(SLS) analysis for massive MIMO UE’s TCP ACK delay
-
UL Traffic generation
• Conventional UE’s UL traffic: FTP 2 model in 3GPP TS 36.814
• DL massive MIMO UE’s TCP ACK traffic: Refer to Appendix
-
TCP ACK delay
- TCP ACK delay = (The time when PUSCH is successfully received) – (The time when DL TCP ACK
packet is generated)
-
Check point: TCP ACK delay analysis for DL Massive MIMO Tput impact

The evaluation for UL impact for M-MIMO DL Tput (2/2)
Results and Analysis
- For UL PRB usage 0/25/50% cases, there are 0/4/8 UEs which send UL traffic.
There are another 8 UEs or 16 UEs which send DL TCP traffic with Massive MIMO.
For those 8UE/16UEs they are send TCP ACK in UL. In total, there are 6 cases.
- From the simulation, the TCP ACK delay for 6 cases results are almost same.
- The PF(Proportional Fairness) scheduler gives higher priority for small BO(TCP
ACK) UE than large BO UE(UL traffic) when UE’s channel condition are same. TCP
ACK delay is almost same regardless the UL load, therefore Massive MIMO DL
Tput is not degraded due to UL.
