What is ICIC in LTE?
ICIC is defined in 3GPP release 8 as an interference coordination technology used in LTE systems. It reduces inter-cell interference by having UEs, at the same cell edge but belonging to different cells, use different frequency resources.
What is ICIC in 5g?
Inter-cell interference coordination (ICIC) was introduced in Release-8/9 of the 3GPP LTE standards. The basic idea of ICIC is keeping the inter-cell interferences under control by radio resource management (RRM) methods.
What is ABS LTE?
As you know, LTE signal (actually most of the communication signal) has two components. So it would be recommended to transmit the signal in very low power in stead of completely stopping the transmission. These subframe with very low signal power is called ‘Almost Blank Subframe (ABS)’.
What is almost blank subframe?
Almost Blank Subframes (ABSs) are an important part of enhanced Inter-Cell Interference Coordination in 3GPP standard. The concept of ABS is to blank some subframes of macro base stations (MBSs), therefore, PBSs can have no interference from MBSs during these periods.
What is ICIC Telecom?
Inter-cell interference coordination (ICIC) techniques present a solution by applying restrictions to the radio resource management (RRM) block, improving favorable channel conditions across subsets of users that are severely impacted by the interference, and thus attaining high spectral efficiency.
What is 4g Sinr?
April 27, 2017 July 21, 2020 Author LTE, RF Basics. SNIR is a measure of Signal Quantity and Interference and Noise Quantity and it is very important measurement in terms of RF and sometime it is also called as SNR in absence of interference.
What is LTE CoMP?
Coordinated multipoint (CoMP) transmission and reception is the key technique in LTE-Advanced to improve the cell-edge throughput and/or system throughput. Joint processing (JP) in CoMP technology provides multiple data transmission points for each user among multiple cooperated radio base stations.
What is inter-cell interference coordination LTE?
LTE uses frequency reuse factor of 1 in order to maximize spectrum efficiency. This inherently means that transmissions carried out on the same time-frequency resource will cause interference between different cells at cell-edges.
What is enhanced inter-cell interference coordination?
LTE-A enhanced Inter-cell Interference Coordination (eICIC) with Pico cell adaptive antenna. The Pico cell examines the interference environment around it and adjusts the antenna radiation pattern to equalize the Signal to Interference Ratio (SIR) along its circular coverage range.
What is Sinr in WIFI?
In information theory and telecommunication engineering, the signal-to-interference-plus-noise ratio (SINR) (also known as the signal-to-noise-plus-interference ratio (SNIR)) is a quantity used to give theoretical upper bounds on channel capacity (or the rate of information transfer) in wireless communication systems …
What is range of Sinr in LTE?
SINR/SNR – The signal-to-noise ratio of the given signal. RSRP – The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm(bad). RSRQ – Indicates quality of the received signal, and its range is typically -19.5dB(bad) to -3dB (good).
What is modulation in LTE?
Modulation is the process of varying the properties of a carrier signal such as frequency, phase and amplitude with a modulating signal that contains the actual information to be transmitted. A modulator does the modulation of a signal and a demodulator does exactly the reverse of modulation.
What does ICIC stand for in LTE technology?
LTE Quick Reference. ICIC(Inter-Cell Interference Coordination) As the term ICIC stands for, it is a type of technology which is designed to reduce the interference created by two or more cells.
How does ICIC reduce inter cell interference?
ICIC is defined in 3GPP release 8 as an interference coordination technology used in LTE systems. It reduces inter-cell interference by having UEs, at the same cell edge but belonging to different cells, use different frequency resources.
What does the type indicate in 3GPP TR 21.900?
NOTE 3: “Type” indicates Technical Specification (TS) or Technical Report (TR). NOTE 4: For definition of “freezing” of specifications (last two colunms), see 3GPP TR 21.900. For publication?
Is the r1-104942 spec reflected in 3GPP?
Following is a kind of baseline idea on the approaches to solution from R1-104942. Some of them has been adopted in 3GPP specification as of now (36.300), but some of them are not reflected in the spec or still need further clarification.
