What is eICIC LTE?
Enhanced Inter-Cell Interference Coordination (eICIC) The enhanced ICIC (eICIC) is introduced in 3GPP LTE Release-10 to deal with interference issues in HetNets, and mitigate interference on traffic and control channels. eICIC feature increases the coverage area of the victim cells without boosting downlink power.
What is ABS LTE?
Enhanced ICIC (eICIC) was introduced in LTE R10. The major change is the addition of time domain ICIC, realized through use of Almost Blank Subframes (ABS). ABS includes only control channels and cell-specific reference signals, no user data, and is transmitted with reduced power.
What is eicic in LTE?
ICIC reduces interference on traffic channels. eICIC stands for Enhanced Inter Cell Interference Coordination. Also referred as Enhanced LTE technique for interference mitigation between macro and pico LTE base stations. This concept is made available in 3GPP release 10.
How to inform the network that a UE supports eicic?
The first step is for a UE to inform the network of whether it support eICIC or not. This information is carried by Feature Group Indicator (FGI) in UE Capability Information message as indicated below.
What is eicic?
■ What is eICIC? eICIC is an interference control technology defined in 3GPP release 10. It is an advanced version of ICIC, previously defined in 3GPP release 8, evolved to support HetNet environments. To prevent inter-cell interference, ICIC allows cell-edge UEs in neighbor cells to use different frequency ranges (RBs or sub-carriers).
What is the difference between eicic and co-channel?
On the other hand, eICIC allows them to use different time ranges (subframes) for the same purpose. That is, with eICIC, a macro cell and small cells that share a co-channel can use radio resources in different time ranges (i.e. subframes).
