According to foreign media reports, the 3GPP RAN working group held a meeting in Busan, South Korea on May 21-25 this week. The meeting will complete the 5G first-stage standard, and Samsung Electronics will host the meeting. About 1,500 experts from global telecommunications companies and chip, mobile and equipment suppliers will attend this week's conference, including Verizon, AT&T, NTT Docomo, KT, SK Telecom and Qualcomm.
Therefore, some media said that all 5G SA standards will be frozen this week, but it is understood that this week is the 3GPP RAN working group meeting, the SA working group will be held next week, the discussion of the RAN working group meeting The results will be submitted to the Plenary in June and the standard will be officially frozen.
(3GPP includes 3 TSGs and 16 working groups)
It is understood that the 3GPP working group is divided into three major areas of RAN, SA and CT. Among them, the RAN is mainly responsible for the content related to the wireless access network, the SA is mainly responsible for the related content such as the service and the system concept, and the CT is responsible for the related contents of the core network and the terminal.
At the last meeting of the upcoming 3GPP working group, the RAN working group will conduct a report summary to determine the final technology of 5G commercialization, including providing ultra-high-speed data transmission and ultra-low latency 5G wireless access technology and 5G terminal conformance test method.
All the media reporters from the communications world interviewed an expert from the China Mobile Research Institute in Busan. The group meeting will determine the first draft of the technical standards, mainly to achieve the function freeze. The June plenary session is equivalent to the seal identification and officially announced. The function freezes. Then, this first draft will be returned to each group again, for the group to continue to review the details, carry out potential technical corrections and detailed improvements, until the September plenary session, to achieve ASN.1 freeze, only to really freeze.
In December last year, 3GPP approved a 5G non-independent (NSA) standard for 5G connectivity using existing 4G LTE as the basis. This week's Busan meeting will complete the 5G Independent Standard (SA), which is expected to be approved and released next month.

It is reported that the RAN4 working group hosted by Samsung will decide the requirements of 5G terminals and base stations including the 3.5Hz and 28Hz bands.
Samsung Electronics has been focusing on 5G development and is striving to occupy a place in the next generation of mobile communications. According to Samsung's official website, as of this month, Samsung has 1,254 patents in 5G, and Samsung Electronics ranked first in the list of 3GPP member companies that filed 5G standard patents with the European Telecommunications Standardization Organization (ETSI). Samsung Electronics signed a 5G fixed wireless access (FWA) commercial agreement with Verizon in January this year. In February of this year, Samsung became the first US government agency to receive Federal Communications Commission (FCC) approval, which is responsible for interstate communications. , 5G wireless access unit and outdoor customer premises equipment (CPE), and get its approved 5G home router (indoor CPE).
