Context

RAN2 sent an LS to 3GPP SA4 in November 2022 in https://www.3gpp.org/ftp/TSG_SA/WG4_CODEC/TSGS4_121_Toulouse/Docs/S4-221229.zip asking that the following two parameters are to be added: "In NR, the frequency parameter is coded as combination of FreqBandIndicatorNR and ARFCN-ValueNR as defined in 3GPP TS 38.331 and TS 38.101." Recently 26.517 was significantly updated in CR 0001 in order to address the removal of XML and only use JSON.

Problem description

There was an oversight to address the request from RAN2 and only the following parameter is added

radio‌Frequency array(Uinteger) M 1..N The transmission frequency (expressed in Hertz) associated with the MBS Frequency Selection Area (FSA) Identifier in the parent service area.

Suggested solution

  • Create a CR to 26.517 and address this issue.
  • Send an LS to RAN2 about the updates
