會議報告 ( 會議類別 : 其他 ) 3GPP RAN Plenary #64 Meeting 會議報告 出席人員 : 陳瓊璋派赴地區 : 法國 Sophia Antipolis 會議期間 :103 年 6 月 8 日至 6 月 15 日報告日期 :103 年 6 月 30 日
摘要 本次 3GPP RAN Plenary #64 會議於 6 月在法國的 Sophia Antipolis ETSI 總部舉行, 本團隊依規劃有一位成員出席, 此行主要任務包括參與 CA LTE-U SDL 等議案討論, 並關注新的 SI 和 WI, 以掌握 3GPP 標準現況與技術發展趨勢 本次會議針對 LTE-U 議題, 特別於周五下午舉辦半天的 workshop, 討論非常熱烈, 預計將成為 R13 SI/WI, 值得提前佈局 另外針對近來非常熱門的 NFV/SDN 技術, 本次會議有提案建議成立新的工作項目來探討, 討論後 3GPP 目前決定先由 SA5 從網管的觀點來評估 NFV/SDN 技術對網路的影響與衝擊, 再來決定後續的行動方案, 值得後續觀察 本次會議另一個爭議較大的議題是 TDD SDL 技術, 提案建議增加 TDD 10:0:0 的組態, 討論後決議至下次會議繼續討論, 有機會成為 R13 的新 feature, 對於 LTE FDD-TDD CA 的運作與營運方式有重大影響, 值得後續觀察 1

( 三 ) 會議紀要 Liaison from Outside 3GPP Group 會議開始先討論外部單位給大會的 Liaison, 包括有 NGMN (Next Generation Mobile Networks) BBF (Broadband Forum) TDIA (Telecommunication Development Industry Alliance) GTI (Global TD-LTE Initiative) IEEE (Institute of Electrical and Electronics Engineers) GSMA (Global System for Mobile Communications Association) FCC (Federal Communications Commission) 等, 摘要說明如下 : RP-140555 : `` LS on the proposal of new Supplemental Downlink for LTE TDD from TDIA TDIA 組織建議 3GPP 暫不要通過 TDD-LTE SDL (Supplemental Downlink) 10:0:0/9:1:0 的組態, 主要的原因包括 : SDL 0:0:0/9:1:0 組態因為沒有 uplink subframe, 因此沒有 Duplexing 的概念, 與 ITU 定義的 FDD/TDD 不符合 SDL 0:0:0/9:1:0 組態因為 uplink subframe, 因此會與 TDD 業者產生嚴重 inter-operator 干擾 3.5GHz LTE TDD ecosystem 尚未成熟, 此時推動將影響既有 TDD 系統的發展 RP-140557 : `` LS on proposal of Supplemental Downlink for TD-LTE from GTI from GTI 本 LS 由 GTI 所提的 contribution 與上一件類似, 都是建議 3GPP 暫不要通過 TDD-LTE SDL (Supplemental Downlink) 10:0:0/9:1:0 的組態, 其所持的理由也類似, 除了以上所列理由外, 並增加 : TDD-LTE SDL (Supplemental Downlink) 10:0:0 組態無法單獨存 5
在, 因此可能有 backward compatibility 問題 RP-140551 : `` LS on Priority Development of 3GPP Mobile Location Accuracy Standards from FCC 本 LS 是美國 FCC 寫給 3GPP, 說明 FCC 對於 Public Safety 與緊急狀況用戶位置定位在法規上的需求, 包括室內定位的需求在內, 因此希望 3GPP 能持續並加速訂定相關的 Public Safety 與戶位置定位相關技術規格 RP-140536 : `` LS on Areas of Mutual Interest to 802 LMSC and 3GPP from IEEE 本 LS 是 IEEE 組織給 3GPP 的一封信, 希望雙方能召開 Tele Conference, 探討在行動領域雙方有無進一步合作的機會 但有些公司傾向認為既有的 Liaison 制度已經可以達到雙方溝通的效果, 毋須召開電話會議 : RP-140545 : `` LS on Publication of GSMA HD Voice Logo Technical Annex F for Mobile Networks and Terminals for the usage of the HD voice logo with LTE from GSMA 本 LS 是 GSMA 組織給 3GPP 的一份參考文件, 內容是 GSMA 最近出版, 統計目前全球有關 LTE 網路與終端支援 HD Voice 的現況, 僅供參考並於特別需求 RP-140532 : `` LS on consolidated operator view on ecomp standardization from NGMN 本 LS 是 NGMN 組織給 3GPP 的一份文件, 內容是表達 NGMN 組織內對於 Non-Ideal Backhaul (NIB) inter-enb CoMP 的看法和需求 本文件說明 NGMN 的 operator 有很大的共識, 希望能盡速於 R12 完成 NIB inter-enb CoMP 的技術規制定, 希望 3GPP 能加速完成 6
