5G New Radio (NR) is the global standard for a unified, more capable 5G wireless air interface. It will deliver significantly faster and more responsive mobile broadband experiences, and extend mobile technology to connect and redefine a multitude of new industries.
Read moreWhat is CCE aggregation level?
The CCE aggregation level is given by the PDCCH format and determines the number of PDCCH candidates in a search space . The number of candidates and size of the search space for each aggregation level is given in the following table.
Read moreWhat is Pdcch 5G?
Similar to the previous radio access systems, e.g., LTE, 5G new radio(NR) uses the Physical Downlink Control Channel (PDCCH) to perform physical layer control functions such as Scheduling the Downlink(DL) broadcast and DL/uplink(UL) unicast data transmission and signaling triggers for periodic and aperiodic transmission …
Read moreWhat is Pdcch blocking?
PDCCH blocking probability is defined as the probability . that all PDCCH candidates configured for a UE to monitor are . blocked by candidates used by other UEs . That is, the blocking. probability is the ratio between the number of the blocked.17 Eki 2020
Read moreWhat is common search space in 5G?
Common Search Space is the specific search space that every UE need to search for the signals for every UE (e.g, PDCCH for SIB) or signaling message that is applied to every UE before dedicated channel is established for a specific UE(e.g, PDCCH used during RACH process).
Read moreWhat is the PRB in LTE?
Abstract: In LTE (Long Term Evolution) systems, the PRB (Physical Resource Block ) usage ratio is considered importantly to manage the QoS (Quality of Service) of LTE traffic. As the PRB usage ratio increases, the resource may not be allocated in a timely and reliable manner to the users of the cell.
Read moreHow does LTE calculate PRB?
Physical Resource Block (PRB) = 2*Resource Block = 12 Subcarriers x 14 OFDM in 1ms . RE can deliver 2, 4, 6, 8 bits in QPSK, 16QAM, 64QAM, 256QAM respectively. If we calculate for 64QAM as 6bits since 256QAM not widely spread (check Samsung S7 in T-Mobile). 20MHz ==> 100 PRB ==> 100*168*1000 = 16,800,000 RE in 1 s.
