LTE49 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.

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. 3GPP LTE Frequency Bands (LTE FDD / LTE TDD) LTE BandUplink Operating BandDownlink Operating BandDuplex ModeF(UL) Low – F(UL) HighF(DL) Low – F(DL) High11920 MHz – 1980 MHz2110 MHz – 2170 MHzFDD21850 MHz – 1910 MHz1930 MHz – 1990 MHzFDD31710 MHz – 1785 MHz1805 MHz – 1880 MHzFDD41710 MHz – 1755 MHz2110 MHz – 2155 MHzFDD5824 MHz – 849 MHz869 MHz – 894 MHzFDD6830 MHz – 840 MHz875 MHz – 885 MHzFDD72500 MHz – 2570 MHz2620 MHz – 2690 MHzFDD8880 .. 2015. 4. 27. 3GPP releases summary Release 8 - LTE Introduced Release frozen in Dec 2008 It was 3GPP release 8 when LTE was introduced for the very first time. All the releases following only enhanced the technology. Based on release 8 standardization, following were the main achievementsHigh peak data rates : Up to 300 Mbps in downlink and 75 Mbps in uplink when using 4x4 MIMO and 20 MHz bandwidth, High spectral efficiency Flexi.. 2015. 4. 27. [LTE] DMCR (Deferred Measurement Control Reading) 관련 LinkLTE Architecture and FEATURES This feature avoids reading SIBs with information that can be received at another occasion. Such information is included in SIB11 and 12. The SIB 11 includes measurement control and neighbouring cell list. As soon as a call is setup in Ericsson WCDMA, intra frequency measurements are started and the information in SIB11 information is retransmitted to the UE... 2015. 3. 17.
