　　With China Radio and television and China Mobile700MHz 5Gnetwork“Co construction and sharing”Cooperation Promotion，All localities are working closely700MHzActual networking process，be based on“Network construction while frequency clearing、Side operation”General ideas for the future，Under the guidance of competent authorities, various localities have also formed multilateral cooperation between mobile and radio and television network companies，Coordinate and promote frequency clearing through a specially established working group。

　　China Radio and television these days（China Radio and Television Network Group Co., Ltd）Completed in Beijing“Meet in Beijing”Ice hockey test events，Mainly5G NRBroadcasting technology has been successfully applied to live broadcasting from multiple perspectives、panoramaVRVerification of new broadcasting services such as live video，And publicized as“The world's first5G NRSystem capability verification of broadcasting technology in commercial scenario”。

　　About China Radio and television5G NRradio broadcast，DVBCNIn the past two years, he has been paying continuous attention to and timely introduced many relevant contents，Including basedLTEThe evolution of broadcasting, etc。It is worth noting that，3GPP RANWorking group in10Another meeting was organized at the end of the monthRel-18 Workshop，All participants continue to18VersionWI、SISeveral rounds of discussion were made on potential items。

　　The items in this series are likeRAN94e-R18Prep-14of“Evolution for broadcast and multicast services”Naturally, there is the deep participation of China Radio and television，3GPPThe summary of the last meeting has also been released，It is expected that2021year12month6~17The corresponding results will be further determined in the e-conference on the th。

　　What the author mentioned this timeRAN94e-R18 Prep-14Focus on two subject items，Namely (NR WID) “Evolution of NR Multicast Broadcast Services”And (LTE WID) “Evolution of 5G LTE based broadcast”，That is based on5G NR MBSMulticast for（Multicast ）Broadcast evolution and based onLTE of5GBroadcast evolution。

　　I have a general understanding，The participants in this discussion are international and domestic mainstream equipment manufacturers、Operator、Broadcasting companies, etc，It also includes China Radio and television。Other representative manufacturers such as Huawei、MediaTek、CATT（Institute of Telecommunications Science and technology）、Samsung UK R & D Center、ZTE、Spreadtrum communication、SHARP、association（Beijing）、Nippon electric、vivo、China Mobile、Ericsson、BBC、LGElectronics、OPPO、NOKIA、high pass、Future Micro Technology、Asia Pacific Telecom、Intel、Apple、EBU、AT&T、SWRetc.。

　　according to11Meeting materials put in at the beginning of the month，First round forNR MBSEvolution item（Evolution of NR Multicast Broadcast Services）During the discussion, China Radio and television believed that it should supportDUbetweenSFNTo improveRel-18inMBSPerformance and spectral efficiency（higher thangNB-DUlevel），Support forNR MBSSpectral efficiency/capacity/Reliability improvement，Enable higher reliability、Lower latency and greater coverage；Its recommendations are highlighted separately in the listRANshare。Should also supportDU/CUSingle frequency network in，To improve Rel-18inMBSPerformance and spectral efficiency。

　　In the discussion of additional objectives，China Radio and television still put forwardFree-to-Air/receive only modeNeeds of，Here, we still consider the needs of public service scenarios，Want to ensure end-to-end support。China Radio and television strongly recommends thatEnhancements for FTA supportAct asNR MBSOne of the support items。

　　aboutEvolution of 5G LTE based broadcast，China Radio and television believes thatRel-18Based on5G LTEBroadcast enhanced demand，Other manufacturers have similar views。butEBUIt is recommended to define to5GCTo supportLTEContinuous evolution of broadcasting。

　　As mentioned earlier，China Radio and television supportRANWriting of shared functions，The actual deployment scenarios and optimization requirements are mainly considered，I think it needs to be improvedNR MBSTransmission efficiency。

　　For free broadcasting/Enhancements to receive only mode“Enhancements for Support of Free-to-Air/receive only mode(pending SA1/SA2 support)”，China Radio and television expressed as yes“This feature is highly recommended asWIDA goal in”，The reason is still the same. The scenario needs for public services mentioned earlier，Its deployment needs to consider unicast andFTAConcurrent transmission of broadcast。

　　In the last roundEvolution of NR Multicast Broadcast Services（NREvolution of multicast broadcasting service）Under discussion，China Radio and television still insistsFTA/ROMEnhancements forNR MBSEvolutionary importance of，It has repeatedly stressed the network it is deploying（That is, radio and television700MHz 5Gnetwork）YesMBSfunction，aboutFTAService inR18The continued support of the version is still the requirement item it adheres to。
