The eNodeB determines the downlink transmit energy per resource element (lte epre). Downlink cell-specific reference-signal (RS) lte epre is constant across the downlink system bandwidth and constant across all subframes until…
The effective Eb/No and hence the spectral efficiency depend on BLER. However there are QoS requirements which also have to be considered. Taking both into account leads to a target…
Higher data rates: Obviously this is a general requirement requested from any new system. Quality of service, Lower delay: To enable true convergence between real-time and non-real-time services quality of…
Fully packet-oriented mobile broadband network providing: – Peak data rates of 100 Mbps (DL) and 50 Mbps (UL) – Very low latency – Seamless and lossless handover – Sophisticated QoS…
3G is new upgraded cdma technology, in simple word its Wide band Code Devision Multiple Access Technology (WCDMA). This is first technology in which video call possible means voice and…
Interference is dependent on time, frequency and mobile location. Without frequency hopping, some cell planning margins must be incorporated so that sufficient service quality can still be provided in an…
ABI Research’s latest forecasts for femtocells estimate largely flat volume shipments in 2012 relative to 2011. The shipments in 2012 are expected to contain 2.44 million units, similar to the…
Below types of information carries By Logical Channel in LTE Control Channels Broadcast Control Channel (BCCH) :used for transmission of system information from the network to all UEs in a…
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…
When the handset first powers up, it does an exhaustive search for the best pilot. No windows are used in this process. On the paging channel, the handset learns the…
