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 OFDM numerology?
OFDM numerology design for wide range of carrier frequencies, deployment types, and application latency requirements using regular slots . 100 GHz. Frequency. 15 kHz. 30 kHz.
Read moreWhat is LTE numerology?
Numerology corresponds to one subcarrier spacing in the frequency domain . NR supports a flexible numerology with a range of subcarrier spacings, based on scaling a baseline subcarrier spacing of 15 kHz. By scaling a reference subcarrier spacing by an integer N, different numerologies can be defined.
