Firstly, lets understand the definition and points where the ERAB KPI is pegged. After the UE sends the RRC Setup Complete message to the eNB, the eNB sends a S1 Initial UE Message to the MME indicating the purpose of the UE (Attach, TAU, CSFB, Service Request etc) and its credentials...
There may be overlapping geographic coverage areas 110 for different technologies. In some examples, the wireless communication system 100 may include an LTE/LTE-A network. In LTE/LTE-A networks, the term evolved Node B (eNB) may be used to describe the base stations 105, while the term ...
Observed Time Difference Of Arrival (OTDOA): The time interval that is observed by a UE between the reception of downlink signals from two different cells. If a signal from cell 1 is received at the moment t1, and a signal from cell 2 is received at the moment t2, the OTDOA is t2...
wherein the one or more processors are configured to cause the UE to: couple the third antenna to the first radio via the switch; transmit, via the first radio while the switch is in the first state, a request to attach to a first network node operating according to the first RAT; tra...
A user equipment (UE) is configured to perform a Hybrid Automatic Repeat Request (HARQ) in an un-licensed system. The UE includes at least one antenna configured to communicate with
In the FFR scheme, the cell coverage region is divided into two non-overlapping regions, namely the inner cell region near the eNB and the outer cell region that covers the edge of the cell. In the sectorization method, the subdivided cell regions are partitioned into three sections with ...
