Questions about RLC mode settings

[fish-debug]

Hi, How to set the RLC mode of millimeter wave to TM mode?

[mychele]

Hi, TM mode is not supposed to be used for data transmission, just for the service bearers for the initial setup of the connection. If you try to force it (for example by modifying the LteEnbRrc::GetRlcType), you may find some bugs due to the lack of features in TM (see for example here: http://www.sharetechnote.com/html/5G/5G_RLC.html#TM_Mode_Procedure). Best, Michele

Hi, Currently I am doing some development on RLC UM mode.I don't want to segment RLC SDUs,and I just want concatenate the RLC SDUs.But when I modify the code there are some errors

aborted. msg="MmWaveNetDevice::Receive - Unknown IP type...", file=../src/mmwave/model/mmwave-net-device.cc, line=233

void MmWaveNetDevice::Receive (Ptr p) { NS_LOG_FUNCTION (this << p); Ipv4Header ipv4Header; Ipv6Header ipv6Header;

if (p->PeekHeader (ipv4Header) != 0) { NS_LOG_LOGIC ("IPv4 stack..."); m_rxCallback (this, p, Ipv4L3Protocol::PROT_NUMBER, Address ()); } else if (p->PeekHeader (ipv6Header) != 0) { NS_LOG_LOGIC ("IPv6 stack..."); m_rxCallback (this, p, Ipv6L3Protocol::PROT_NUMBER, Address ()); } else { NS_ABORT_MSG ("MmWaveNetDevice::Receive - Unknown IP type..."); } } Can you give me some suggestions？Thank you very much.

Hi, this suggests that the packet that you are receiving at that point of the stack has not a well-formed IP header (it may have some other headers on top of it). Michele
