Mobile/LTE and 5G56

[5G NR] IoDT (Interoperability Development Testing) InterOperability Device Testing (IODT) determines whether the base station and device can establish and maintain a robust communication link that can carry out 5G performance in prescribed test conditions. https://www.mediatek.com/blog/worlds-first-multi-vendor-5g-nr-standalone-data-call World’s first multi-vendor 5G NR standalone data call In a collaboration between MediaTek, T-Mobile, Ericsson.. 2019. 8. 20.
Mobile Signal Strength Recommendations Signal Measurement Signal strength values are defined by a few different measurements which vary even more for different service modes. These measurements are as follows: 2014/08/12 - [Mobile/LTE and 5G] - [LTE] RSSI, RSRP, RSRQ, RSCP, SINR, EC/IO [LTE] RSSI, RSRP, RSRQ RSSI (Received Signal Strength Indicatior) - 단위 dBm (절대크기) - 단말에 수신되는 모든 Power의 총 크기 - 신호 세기에 인접한 채널의 간섭, 열 잡음 포함 - 2G (GSM)에서 .. 2019. 8. 10.
5G can cover up to 65 percent of the world’s population in 2024 Key findings In 2024, 5G can cover up to 65 percent of the world’s population. LTE increased by some 10 percentage points during 2018, creating the potential for around 750 million more people to utilize the technology. LTE population coverage is forecast to reach around 90 percent in 2024. Looking at the first two categories combined, 5G population coverage is forecast to reach 45 percent in 20.. 2019. 8. 9.
5G smartphones in all three spectrum bands are expected to be available in 2019 Key findings Over 10 million 5G subscriptions are projected worldwide by the end of 2019. There is a strong commitment and increasing 5G focus from chipset and device vendors. The first wave of 5G services and device launches will be based on Non-Standalone (NSA) architecture. Suppliers are already working on the first chipsets supporting Standalone (SA) architecture and devices are expected in .. 2019. 8. 9.
5G NR의 정의와 5가지 혁신 기술 무선기술 분야는 최근 수십 년 동안 빠르고 놀라운 변화와 혁신을 보여줬습니다. 3G Data 서비스와 스마트폰 보급으로 인해 모바일 폰의 인터넷 사용량 및 다양한 생활 및 산업 인프라에 많은 변화가 이루어 졌고, 4G가 상용화 되면서 향상 된 효율성을 제공하는 모바일 네트워크를 기반으로 산업 인프라가 변화되기 시작했습니다. 이젠 5G 상용화를 통해서 보다 넓고 보다 포괄적인 산업의 변화를 가져오기 시작했습니다. 퀄컴, 미디어텍 및 삼성LSI 등의 솔루션 업체들은 SoC를 출시하고 서비스를 제공함으로 장비 회사들과 함께 5G 모델의 상용화를 이끌고 있습니다. 2016년 3월 이후 3GPP는 무선 기술을 통합하고 보다 나은 기술을 제공하기 위한 기술 표준화에 노력을 기울이고 있습니다. 그리고 5G NR 기술.. 2019. 8. 9.

LTE : DRX (Discontinuous Reception) - CDRX (Connected Mode DRX) http://www.sharetechnote.com/html/Handbook_LTE_DRX.html Even while there is no traffic between the network and UE, UE has to keep listening to Network. At least it should be ready to decode PDCCH. It means UE has to be "ON" all the time even when there is no traffic. But being ON all the time would drain the battery.You may ask "Then why don't UE shut down (getting into a sleep mode) when there .. 2016. 12. 30.
LTE: CDRX - Connected Mode DRX http://know-lte.blogspot.kr/2016/07/cdrx-connected-mode-drx.html Connected Mode DRX (CDRX)In addition to Idle mode DRX, LTE had RRC mode DRX as well also known as Connected Mode DRX (CDRX), the purpose of both the DRX is same to conserve the battery power. During RRC connected state when there is no data transmission in either direction (UL/DL) UE goes into the DRX mode. It starts monitoring the.. 2016. 12. 30.

Service Specific Access Control (SSAC) in 3GPP Release 9 In an emergency situation, like Earthquake or Tsunami, degradation of quality of service may be experienced. Degradation in service availability and performance can be accepted in such situations, but mechanisms are desirable to minimize such degradation and maximize the efficiency of the remaining resources. When Domain Specific Access Control (DSAC) mechanism was introduced for UMTS, the origi.. 2015. 9. 8.
