Mobility enhancement in E-UTRAN Release -16

  November 16, 2020    

 Dual Active Protocol Stack (DAPS) handover DAPS Handover is a handover procedure that maintains the source eNB connection after reception of RRC message for handover and until releasing the source cell after successful random access to the target eNB. -    If DAPS handover is configured, the UE continues the downlink user data reception from the source eNB until releasing the...

DL MIMO efficiency enhancements for LTE

  November 16, 2020    

MIMO is an effective technique to improve spectral efficiency and increase overall network capacity. SRS can be utilized to improve DL MIMO performance, especially for massive MIMO in TDD. In release-16 SRS capacity and coverage are enhanced by introducing more than one SRS symbol in a UL normal subframe and introducing virtual cell ID for SRS. More than one symbol for SRS in a UL normal subframe With...

LTE in high speed

  November 15, 2020    

 In Rel-13 and 14, the mobility and throughput performance were enhanced to cover high speeds (up to 350 km/h) by specifying the requirements for UE RRM, UE demodulation and base station demodulation, considering the two types of operator’s practical deployments shown...

MTC enhancements for LTE - Rel 16

  November 15, 2020    

Release 16 adds on the LTE features for Machine-Type Communications (MTC) introduced in earlier releases (e.g. low-complexity UE categories M1 and M2, and Coverage Enhancement Modes A and B) by further improving network operation and efficiency in a range of areas.All New features are optional for the UE and can be supported by Cat-M1 and Cat-M2 and by normal LTE UEs supporting CE mode unless explicitly...

Enhancements of Public Warning System - Rel 16

  November 07, 2020    

The ePWS feature enhances the Public Warning System by defining behaviours for UEs with no user interface or with a user interface that is incapable of displaying text-based Warning Notifications and providing how to improve the comprehension of a Warning Notification to users with disabilities who have UEs supporting assistive technologies beyond text assistive technologies and users who are not fluent...
