Release 17

More 5G system enhancements are set to follow in Release 17, scheduled for delivery in 2021.

July 3, 2020 Update:

Discussions at TSG#88-e Plenaries identified that the Rel-17 dates are at a high risk of being delayed. This is due to the switch from physical meetings to e-meetings. In SP-200606, the Work Plan manager noted that both SA2 for Stage 2 work (SP-200536) and TSG RAN (RP-201257) had warned that Rel-17 dates will have to be shifted. This will be further discussed in Sept 2020, during TSG#89-e.

At TSG#87e (March, 2020) the following Rel-17 timeline was agreed:

  • Rel-17 Stage 3 freeze September 2021
  • Rel-17 ASN.1 and OpenAPI specification freeze: December 2021
