[STDS-802-11] Liaison document posted: from 3GPP RAN/RAN2 re: RoHC utilization for Ethernet header compression

802.11 members,

IEEE 802 has received the liaison in https://mentor.ieee.org/802.11/dcn/19/11-19-0542-00-0000-liaison-from-3gpp-ran2-re-ls-on-rohc-utilization-for-ethernet-header-compression.docx regarding definition of a new Robust Header Compression profile for Ethernet Header Compression. The context of the proposed definition is for inclusion in the Technical Report of the 3GPP Study Item on NR Industrial IoT, and efficient Time Sensitive Networks (TSN) support over a 5G/NR system.

Please review this received liaison, specifically Q1 and Q2 asked of IEEE 802 (see below) and let me know of any concerns.

Thanks,

Dorothy

=====================

"As can be seen, 3GPP RAN WG2 is not certain about the procedural aspects of defining a new RoHC profile for Ethernet header. Therefore, 3GPP RAN WG2 would like to ask IETF and IEEE the following questions:

 

Q1: Does IETF or IEEE have any concerns with 3GPP defining new RoHC profile for Ethernet header compression?

Q2: Does IEEE have any concern with 3GPP specifying a new Ethernet header compression algorithm?

Q3: In case 3GPP is allowed to develop RoHC profile for Ethernet header compression, does it have to be registered with IANA. If yes, how long can such process take?

Q4: According to IETF, what are the actions needed of 3GPP to specify and maintain a ROHC profile?

3GPP RAN WG2 would like to clarify that it intends to specify the new profile for its own purposes mainly, as described above, but would have nothing against IETF, IEEE or any another party using the profile, once it is defined. 3GPP RAN WG2 is open to collaboration with IETF/IEEE on new profile definition, but would like to indicate that the target completion date of the related work is end of 3GPP Rel-16, which is planned for Q1 of 2020."
