Fragment Lifecycle In Android:

November 27, 2018

Fragment Lifecycle In Android A Fragment represents a behavior or a portion of user interface in a FragmentActivity. You can combine multiple fragments in a single activity to build a multi-pane UI and reuse a fragment in multiple activities. You can think of a fragment as a modular section of an activity, which has its own lifecycle, receives its […]

Android Service Tutorial

November 26, 2018

Android Service Tutorial Android service is a component that is used to perform operations on the background such as playing music, handle network transactions, interacting content providers etc. It doesn’t have any UI (user interface). The service runs in the background indefinitely even if the application is destroyed.service can be bounded by a component to perform interactivity and […]

NR Physical Layer Specifications in 5G overview

November 26, 2018

A Work Item of the detailed specifications of 5G RAN for 5G commercial services is being conducted in 3GPP. The non-standalone NR specifications, which enable early deployment of NR carriers by exploiting LTE/LTE-Advanced carriers as the master node carriers, were completed in December 2017. In June 2018, the standalone NR specifications, which require full NR […]

8.BWP/CA ( NR Physical Layer Specifications in 5G )

November 26, 2018

In NR BWP/CA NR Physical Layer Specifications in 5G, the maximum bandwidth per carrier is much larger than in LTE: 100 MHz at frequencies below 6 GHz and 400 MHz at higher frequencies. For carriers operated with such a large bandwidth, NR supports the BandWidth Part (BWP) concept whereby user equipment can use smaller bandwidths […]

6.Modulation and Channel Coding Schemes (NR Physical Layer Specifications in 5G)

November 26, 2018

Tables 2 and 3 show the modulation and channel coding schemes that can be used for NR downlink and uplink communication, respectively. Modulation Schemes As the primary modulation scheme, in addi- tion to the schemes specified since Release 8 LTE, 256QAM and π/2-BPSK that are available in the latest LTE are also supported in NR. […]

5.Scheduling/HARQ ( NR Physical Layer Specifications in 5G )

November 26, 2018

In NR, as in LTE, the downlink data channels and uplink data channels are scheduled based on the Downlink Control Information (DCI). The DCI is transmitted and received via the Physical Down-link Control CHannel (PDCCH). As in LTE, it is possible to use the frequency domain resource as- signment field included in DCI to allocate […]

4. MIMO/Beamforming / NR Physical Layer Specifications in 5G

November 26, 2018

4.1 MIMO Transmission Method In the high-frequency band, it is very important to obtain a high beamforming gain(Gain: One of the radiation characteristics of an antenna. An indicator of how many times larger the radiation strength in the antennaʼs direction of peak radiation is relative to a stand- ard antenna) by using many antennas to compensate […]
