Hi Brahmareddy, If I remove the text in braces in you question then it would look like generic question for me: How UE recognizes DCI in PDCCH. As we know there are meny DCI formats used in LTE. And there are stages in which specific DCI formats needs to be looked at: for example when UE is trying...

Hi all Greetings. I have a question on PDSCH resource scheduling. Suppose PCFICH indicates 3 OFDM symbols for PDCCH and PDCCH doesn't' occuy all the REs in these three OFDM symbols. in this case can we use the unoccupied REs in the first three OFDM symbols for PDSCH transmission?...

Hello! I'd like to ask experts for clarification. Standard specifies, that PDCCH comes at the beginning of every DL subframe, every subframe for FDD case. Then, PDCCH itself is an aggregation of one or several CCEs. I read this statement as "at least one CCE" has to be transmitted in...

Hello, Please help with my doubt. Assume there is initial access of UE to the network. At step 2 of RA Procedure eNB sends RA Response. RAR is transmitted on PDSCH. To let UE know about that transmission eNB must configure control channel. As far as I can see, either DCI format 1A or DCI format...

Hi, When using Normal Cyclic Prefix configuration, within 1 slot, the specification says CP length for l=0 is 160 CP length for l=1,2 ...6 is 144 I am trying to find out why there are two different CP lengths in one slot, (i.e 160 IFFT samples are appended just for symbol 0 and 144 for the...

After the eNB decodes the Message 1 from the UE (a maximum of 54 may be possible if all preambles are used and no collisions occur), how many of them can be given the upling scheduling grants? If I understand correctly, a maximum of 8 CCEs may be used for this purpose.

Rate matching constitutes of an subblock interleaver & bit collection, selection, & transmission stage as per Release 8, 3GPP TS 36.212, 5.1.4. The input parameters for the convolutionally coded transport channels are: - "d" = input bits - "D" = number of input bits...

The payload length for DCI format 3 versus format 3A is identical irrelevant of bandwidth, TDD or FDD, or choice of the number of antennas. (3GPP TS 36.212, 5.3.3.1.6 & 5.3.3.1.7.) The RNTI mask & search space is identical as well for the two formats. (3GPP TS 36.213, Table 8-7 & Table...

hi, it is written in 3GPP TS 36.211 section 6.8.2: " If necessary, <NIL> elements shall be inserted in the block of bits prior to scrambling to ensure that the PDCCHs starts at the CCE positions". Suppose i have 57 QPSK symbols for one PDCCH, it suggests aggregation level L=2, one...
