Body 
1. Overall Description:
As part of liaison statement R2-1902372 (LS on RoHC utilization for Ethernet
header compression), 3GPP RAN WG2 had requested input on questions about
procedural aspects related to defining a new RoHC profile for Ethernet header
compression.

3GPP RAN WG2 thanks IEEE and IETF for considering the liaison statement. 3GPP
RAN WG2 also thanks IETF for their response (‘In Response to 3GPP RAN2’s LS on
RoHC utilization for Ethernet header compression’).

In 3GPP RAN2#105bis meeting (8th April - 12th April 2019), 3GPP RAN WG2 agreed
to develop new Ethernet header compression algorithm without relying on RoHC
and without using a new ROHC profile. Given this agreement, 3GPP RAN WG2 would
like to withdraw the questions in R2-1902372.

2. Actions:
To IEEE:
ACTION:   3GPP RAN WG2 respectfully asks IEEE to take note of the above.

3. Date of Next TSG-RAN WG2 Meetings:
3GPP RAN2#107           26 – 30 August 2019             Czech Republic
3GPP RAN2#107bis                14 - 18 Oct 2019                China
