VOLTE OPTIMIZATION DROP

VOLTE COVERAGE IMPROVEMENT  Optimization Feature TTI Bundling TTI bundling is specified in 3GPP (TS 36.213, 36.321) to allow the improved uplink performance for cell border UEs (which often hit the maximum transmission power) and for reduced PDCCH load. TTI bundling allows for transmitting the same transport block in 4 consecutive…

DSS – Dynamic Spectrum Sharing 5G-LTE

DSS – Dynamic Spectrum Sharing 5G-LTE

Dynamic Spectrum Sharing (DSS) allows operating LTE and NR networks in the same frequency bands. Dynamic Spectrum Sharing (DSS) is useful to allow operators to perform a soft refarming of the LTE spectrum towards NR. For Dynamic Spectrum Sharing support between LTE and NR in TDD bands. Some operators do…

5G Identifier

  What is 5G Identifier?   Identifiers play an important role in the 5G System, for example, the permanent and temporary subscriber identities are constructed to identify not only a particular subscriber, but also the network function(s) where the permanent and temporary subscriber records are stored.   The network identifiers…

5G NR Antenna Port

5G NR Antenna Port

What is Antenna Port? An antenna port is in the 3GPP specifications an abstract concept that is a logical entity rather than a physical antenna. Each antenna port is associated with a specific set of reference signals such that the channel over which a symbol is transmitted on that antenna…
