TSG Working Agreements
"Working Agreements" are tentative decisions reached by 3GPP groups in order to make progress on matters where consensus [1] cannot be reached. See the 3GPP Working Procedures, article 25. See document PCG20_04 (slides 4 & 5) for further background information.
To propose additions to this page: 3GPP Contact .
Only working agreements explicitly documented in meeting reports will be included. Where appropriate, reference may be made to a meeting contribution (TDoc) supporting the working agreement, or giving further details.
To challenge a working agreement, contact the chairman of the meeting where the challenge would be resolved. The challenge will normally result in a formal vote at the earliest possible meeting. See the 3GPP Working Procedures, articles 25 & 26.

| 33 | The SA6 Chairman declared during the SA6#34 meeting that the Rel-16 Change Request in TDoc S6-192217 be agreed as a working agreement due to objections from only 2 companies while 12 companies were in favour of the CR. The CR removes the ‘temporary re-group procedures’ from Rel-16 due to no progress on corresponding security solution. As a compromise, the procedures have been included in Rel-17 to allow for potential resolution during Rel-17 timeframe. | 2019-11-15 | SA6#34 | S6-192217 | 2019-12-02 | SA#86 | Not yet challenged |

CT1 has decided that an explicit indication in the SIB of support for "attach without PDN connectivity" by the network, will prevent the UE from having to discover availability of such a feature by using trial and error in Attach request and will facilitate handling when UE moves across tracking areas or changes PLMNs. |

RAN4 way forward on Band 28 as global band had sustained opposition by a small minority preventing a consensus. The working agreement was made for the way forward in R4-146724. RAN4 received an LS from CEPT (R4-143812) requesting to harmonise the out of band requirements for 700 MHz mobile terminals between Europe and other regions. Agreement was to delete NS_24 from Rel-12 and add the -42dBm/8MHz associated to NS_01 for 10MHZ E-UTRA carrier within 703-733MHz, Otherwise -25 dBm/8MHz apply. -42dBm/8MHz will be specified in Rel-11 version of TS36.101. CRs for Rel-11 and Rel-12 will be approved in RAN4-73. |

RAN4 CR on Maximum allowed UL TX power for Band XXVI coexistence with Public Safety: CR 1041 (R4-144970) to TS 25.101 Rel-11, and CR 1042 (R4-144971) to 25.101 Rel-12, had sustained objection from Qualcomm. The topic had already been discussed at length in the previous RAN4 meetings, and the working assumption was made that these two CRs were agreed. The two CRs introduce UL power restrictions for single and dual carrier for certain uplink center frequencies for coexistence with Public Safety and Band 27 and they allow power averaging for the 6.25 kHz measurement bandwidth similar to requirements for protection of Public Safety in the 700 MHz band. |

| 6 | "The emission requirement for Band 26 shall be -53 dBm / 6.25 kHz." The OOBE limit for co-existence with narrow band systems in the 851-859 MHz range is the only remaining issue blocking the approval of the WI e850_UB-Core. The topic has been discussed for a long time without reaching consensus. A substantial majority of individual members are in favour of -53 dBm / 6.25 kHz emission requirement for Band 26 but there is sustained opposition preventing consensus on this value. |

| 5 | Three RAN4 CRs for band 3.5GHz (WI code RInImp8-UMTSLTE3500): CR1140 (R4-114395) to TS 25.133, CR838r1 (R4-114755) to TS 25.101, and CR908r1 (R4-114762) to TS 36.101, had sustained objection from Qualcomm. The Topic had already been discussed at length in the previous RAN4 meetings, and the working assumption was made that these three CRs were agreed defining the requirement for tolerance for Maximum output power for LTE and for maximum output power and reference sensitivity for UTRA. | 2011-08-29 | R4-60 | R4-114395, R4-114755, R4-114762 | 2011-09-06 | RP-53 | Unchallenged by date limit thus implicitly confirmed |

At RAN #48, RAN4 CR0530r1 to TS 36.101 "E-UTRA;User Equipment (UE) radio transmission and reception" v9.3.0 in RP-100683 had one sustained objection against the modification in table 7.3.1-2 for the case E-UTRA band 20 (see TS 36.101 table 5.5-1, WI RInImp9-UMTSLTE800EU) for the 10MHz channel bandwidth. The objecting company proposed RP-100684 instead. The topic had already been discussed at length in the previous RAN4 meeting and there were strong market requirements in favour of a conclusion at RAN#48. As a working agreement the CR in RP-100683 was approved (to avoid delay in LTE UE implementation) for implementation after RAN#48. | 2010-06-04 | RP-48 | RP-100683 | 2010-09-07 | RP-49 |

CEN TC 278 WG 15 recommended to make the necessary changes to overcome the problem described in the LS from CEN to ETSI MSG forwarded to SA1 and SA4, i.e. to change the eCall initiation sequence, so that eCall equipped PSAPs only emit a SEND MSD message (in-band tone) in response to a valid incoming eCall INITIATION message from a vehicle eCall terminal (i.e. push mode) - the "In-Vehicle System" (IVS). Accordingly SA1 produced three CRs to TS 22.101 to be submitted to SA Plenary #45 for approval to clarify the service requirement, conditional on SA4 agreeing to include push mode operation. The CRs in question are: S1-093004 22.101 CR314 eCall mode of operation (Release 8), S1-093289 22.101 CR317 rev 1 Minimise delay to emergency voice calls (Release 8), and the "mirror CR" in S1-093290 22.101 CR315 rev 1 Minimise delay to emergency voice calls (Release 9). However concerns were raised at SA1 and later at SA4 about potential impacts of the changes proposed in S1-093289 and S1-093290. Those impacts are related to the situation where the push mode is facing some waiting / welcome messages on 112 lines. | 2009-08-24 | S4-55 | S4-090552 26.267 CR3r1 "Integration of IVS-initiated signalling option", S4-090473 26.268 CR7 "Integration of IVS-initiated signalling option" | 2009-09-14 | SP-45 |

[1] Consensus is defined as the lack of sustained opposition. A working agreement representing the majority view is typically arrived at if only a very small number of individual members sustain opposing views.
