Inter-Frequency Handover means mobility in connected mode between two different cells and different LTE frequencies, This topic will be assigned to Event A5 which is used for LTE Inter-Frequency handover. This event type is a little bit different than Inter-Frequency READ MORE

Inter-Frequency Handover means mobility in connected mode between two different cells and different LTE frequencies, This topic will be assigned to Event A4 which is used for LTE Inter-Frequency handover. It is recommended to have a look HO Events in READ MORE

Intra-Frequency Handover means mobility in connected mode between two different cells, but within same LTE frequency, This topic will be assigned for Event A3 which is used for LTE Intra-Frequency handover. This event type can also be used for Inter-Frequency READ MORE

Normally LTE UE makes radio measurement in two stages which are idle and connected states. In idle state mode the measurement is used for cell selection and cell re-selection. In connected state mode, the measurement is used for handover and READ MORE

Until 3GPP Release 10, we could achieve maximum 150 Mbps downlink throughput with 20 MHz bandwidth, but in 3GPP Release 10 a new mark of LTE was introduced where several frequencies can be aggregated. The new mark of LTE was READ MORE

Long-Term Evolution or with abbreviated version LTE is a standard for high-speed wireless communication. It is based on the GSM/EDGE and UMTS/HSPA technologies. First step of LTE starts from 3GPP Release 8. Currently we can see three marks of LTE which are separated from each other according to the READ MORE

Orthogonal Frequency Division Multiple Access or with abbreviated version OFDMA is a methodology of digital data, that a signal is splitted into multiple carrier frequencies (subcarriers). OFDMA is a multi-user version of OFDM scheme. OFDMA allows multiple users to transmit READ MORE

Reference Signal Received Quality or with abbreviated version RSRQ is quality of the received signal. Here the “received signal” is reference signal (RSRP). But, how do we see the RSRQ value as negative in drive-test tools and why do we READ MORE

Reference Signal Received Power or with abbreviated version RSRP is linear averaged signal strength of Reference Signal. The Reference Signal is carried by Resource Elements (RE). RSRP is used for cell selection, cell reselection and handover purposes in LTE. It READ MORE

If the erroneous packets are received by eNodeB or UE in radio interface, what kind of action will be taken? In intelligent technology there should be a mechanism to solve this issue. And there is, which is Hybrid Automatic Repeat READ MORE
