3GPP Rel-17 可能要立项的课题 (NR light, Small data, Multi sim, 52.6G)

在3GPP RAN#84次会议上，各个通信公司发表了各自对于Rel-17立项的观点。经过激烈的讨论后，大家提取出较多公司支持的立项进行下一步的邮件讨论。

下面把RAN主席总结的Rel-17可能的立项信息（参考RP-191551）总结如下，供大家查阅。

---

[NR_Light]  (moderator: Ericsson)

•Define use cases and scenarios

•Optimal operation for mid-tier NR devices (e.g MTC, wearables, etc…)

•Coverage recovery for NR-Light devices (needed due to antenna gain loss)

•Includes power saving specific for these devices

•No LPWA, no URLLC-specific enhancements

 

[Small_data] (moderator: ZTE)

•Small Data and Inactive Data transmission (both UL and DL)

•No LPWA

 

[Sidelink_enh] (moderator: LG, Oppo)

•Includes V2X, Commercial, and Critical Comms, FR2 aspects

•Relay aspects, architecture aspects, related Uu aspects

•Focus on common functions across the key use cases

•Achieve maximum commonality between commercial, V2X, and Critical Communication usage of sidelink while addressing their specific requirements

•Consider spinning off non-sidelink V2X aspects into a separate thread

 

[NR_above_52.6 GHz] (inlc 60GHz unlicensed) (moderator: Intel)

•Scoping, including structure of the study to enable waveform decision, and decision cut off point (between waveforms)

 

[Multi_SIM] (moderator: Vivo)

•Identify the RAN impact of target use cases until September

•Scoping of WID after September

 

[NR_multicast_broadcast] (moderator: Huawei)

•Main drivers: V2X and Public Safety (incl. ‘mixed mode’ from Rel-16 discussions)

•Refer to RP-190717 as a principle

 

[Coverage_enh] (moderator: China Telecom)

•Clarify requirements for all relevant scenarios focusing on extreme coverage (not including LPWA). Data rate target FFS.

•Start from Rel-16 email discussion outcome

•Includes both indoor as well as wide area

 

 

[IIoT_URLLC_enh] (moderator: Nokia)

•Addressing wider use cases

 

[MIMO_enh] (moderator: Samsung)

•Enhancements motivated by current commercial deployments

•Expand use cases

•E.g. Support for cases with high speed mobility, better support for FDD

 

[Non_Terrestrial_Networks] (moderator: Thales)

•Goal: scoping of the normative WID. Include NTN-specific positioning

 

[NB_IoT_eMTC_enh] (moderator: Huawei)

•Clarify motivation for further enhancement

•Enhancements motivated by current commercial deployments

 

[IAB_enh] (moderator: Qualcomm)

•Includes duplexing enhancement

•Potentials for network coding

•Mobile IAB

 

[Unlicensed_enh] (moderator: Nokia)

•Generic unlicensed operation enhancements not covered by any other item are addressed here

•Unlicensed aspects specific to other items will be addressed by those items

 

[Powersaving_enh] (moderator: Mediatek)

•Enhancements for powersaving of smartphones

•Network power saving aspects as a separate sub-discussion

 

[RAN_datacollection_enh] (moderator: CMCC)

•Includes SON and MDT

•To start based on Release 16 scope and status (leftovers, etc…)

•Data collection to enable AI is part of this discussion

 

[Positioning_enh] (moderator: Qualcomm)

•Factory/campus positioning, IoT, V2X positioning, 3D positioning, cm level accuracy, incl latency and reliability improvements

•NR-U positioning aspects

•Idle and inactive
