"SpletPDCCH blocking can occur when the network is overloaded and there are more scheduling assignments or control messages to be transmitted than there are available resources on the PDCCH. This can lead to delays in the transmission of control information, which can negatively impact the performance of the network. " - Pdcch blocking rate

Pdcch blocking rate

SpletGenerally, the PDCCH blocking rate increases when higher ALs are used. Hence, reducing the number of Rx branches may result in a higher PDCCH blocking rate. In general, the impact on PDCCH blocking performance from RedCap UEs would depend on various factors such as the number of UEs which need to be scheduled (may depend on the … SpletThus, a blocking probability in a PDCCH scheduling process is reduced, and reliability of PDCCH transmission is raised.
