HI,
Data should be filled in pdcch REGs in time first fashion, that is, for example if we have 2 symbols then we will have REG0 in first ofdm symbol, REG1 in second ofdm symbol and REG2 again in 1st OFDM symbol and so on, but in each REG data will be inserted in frequency first fashion. My doubt here is that in, "Downlink Control Processing and Procedures" example, function "hPDCCHSpace" is generating a column vector for indexes for pdcch but these indexes are numbered entirely in frequency first fashion and then direct pdcch to REG mapping is performed which i think should not be the case. What i believe should be that the vector should have first 9 indexes of pdcch of REG0 should be created then 9 indexes of REG1(which is in 2nd symbol, so indexe should jump by NRB*12) and so on.
I am a little confused here, can you please explain on this?
