A physical resource block PRB grid finger is designed so that the terminal device in the 5g system acquires the position of the PRB in the system common PRB grid and the terminal device in the 5g system acquires the relationship between the system common PRB grids corresponding to the sub ...
the spectrum utilization for LTE is 90 percent. That is, 100 of the 111 possible physical resource blocks (PRBs) are utilized in a 20MHz bandwidth allocation. For NR, it has been agreed that the spectrum utilization will be greater than 90 percent. Windowing...
For two antennas, Tx diversity is based on the so-called space frequency block coding (SFBC), which is equivalent to Alamouti coding in the frequency domain. With four Tx antennas, SFBC is used in combination with the so-called frequency-switched transmit diversity (FSTD) . There is also a...
If enough mobiles in a cell run such applications, then the base station serving the cell can quickly exhaust its transmit power resources. This type of resource limitation is termed power-limited. Orthogonal transmit diversity (OTD) and space time spreading (STS) are two transmit diversity ...
Focusing on wireless communication systems, in recent years Machine Learning applications to the upper layers have been minutely explored for various purposes, like the deployment of cognitive radio and Self Organized Networks or the resource management, while its application to the physical layer has ...

12 subcarriers form one PRB (Physical Resource Block). 5G NR supports 24 to 275 PRBs in a single slot. Occupied BW of 34.56 MHz (minimum) and 396 MHz (maximum) can be achieved for 120 KHz subcarrier spacing. One SS/PBCH Block occupies 4 OFDM Symbols in time domain and 24 PRBs in...
