SpletPDCCH order is a mechanism for eNB to trigger RACH procedure in connected mode in order to recover the sync. Refer to PDCCH Order page for the details of RACH Triggered by PDCCH Order. I wrote a separate page because there are pretty much details on PDCCH Order itself. SpletEach space comprises 2, 4 or 6 PDCCH candidates whose data length depends on the PDCCH format; each PDCCH must be transmitted on 1, 2, 4 or 8 CCE(s) (1 CCE = 9 REGs = 9*4 REs = 72 bits). The PDCCH candidates consist of consecutive CCEs. The candidates within the PDCCH candidate set do not have to be unique, especially for smaller …
