LTE

Here we discus about LTE Technology, detail on 4G and How to LTE.


EPS Bearer Terminology in LTE

EPS Bearer Terminology in LTE   Quality of service GBR bearer: Guaranteed bit rate Non-GBR bearer: No guaranteed bit rate Establishment time Default bearer Established when UE connects to PDN

Inter-cell interference coordination (ICIC) in LTE

Inter-cell interference coordination (ICIC) in LTE To aid downlink ICIC Relative narrowband transmission-power indicator A cell can provide this information to neighboring cells, indicating the part of the bandwidth where

BENEFITS OF MULTI-ANTENNA TECHNIQUES IN LTE

BENEFITS OF MULTI-ANTENNA TECHNIQUES IN LTE The availability of multiple antennas at the transmitter and/or the receiver can be utilized in different ways to achieve different aims: Multiple antennas at

LTE Downlink & Uplink Physical Channel

LTE Downlink Physical Channel Physical Downlink Shared Channel ( PDSCH) This channel is used for unicastand paging functions. Carries the DL-SCH and PCH. QPSK,16-QAM,and 64-QAM Modulation. Physical Downlink Control Channel

Packet-Switched Radio Interface in LTE

LTE has been designed as a completely packet-oriented multi service system, without the reliance on circuit-switched connection-oriented protocols prevalent in its predecessors. In LTE, this philosophy is applied across all

Transmit Diversity & Receive Diversity

Transmit Diversity MISO = Multiple Input Single Output Principle More complex than SISO. 2 or more transmitters and one receiver. MISO is more commonly referred to as transmit diversity. The

LTE Downlink Logical Channel

Paging Control Channel(PCCH) A downlink channel that transfers paging information and system information change notifications. This channel isused for paging when the network does not know the location cell of

Handover Measurements in LTE

Measurements to be performed by a UE for intra/inter-frequency mobility are controlled by e-UTRAN, using broadcast or dedicated control. If the frequency center of the measured cell is the same

Intra E-UTRAN Handover in LTE

The UE is RRC connected. During the HO: The radio link is released from the eNodeB 1 and re-established on the eNodeB 2 The Control plane is switched to the
