How this tool
works?
This tool can
be used to calculate the Physical Resource Block number (nPRB) to be used for
transmission of PUCCH in the Even
and Odd slots for PUCCH Formats 1x,
2x, and 3.
Bandwidth
must be selected in order to calculate nPRB for all PUCCH formats.
For all PUCCH
Format 1x, checkbox ‘ExtendedCP’ can
be used to toggle between normal and extended cyclic prefix, the nPRB
calculation depends on this selection. For PUCCH Formats 2x and 3, it has no
effect.
For all PUCCH
Format 1x, deltaPUCCH-Shift, nRB-CQI, and nCS-AN are to be taken from PUCCH-ConfigCommon
.
PUCCH formats
1a, 1b, and 1b with channel selection (and no collision with SR) need n1PUCCH-AN (from PUCCH-ConfigCommon) and nCCE
(the number of the first (lowest) CCE index).
For the cases
where a positive SR is scheduled, sr-PUCCH-ResourceIndex shall be
taken from SchedulingRequestConfig
.
Use PUCCH
Format 1 for calculating nPRB for the following scenarios:
1.
1. Only SR transmission
2.
2. SR and HARQ-ACK
collision. The actual PUCCH format used is either 1a or 1b depending upon the
number of HARQ-ACK bits but for the calculation of resources in this tool one
can use ‘PUCCH Format 1’.
3.
3. SR and HARQ-ACK
collision with format 1b for up to 4-bit HARQ-ACK with channel selection. The
actual PUCCH format used is 1b with channel selection but for the calculation
of resources in this tool one can use ‘PUCCH Format 1’.
In order to
calculate nPRB for PUCCH Format 2/2a/2b, cqi-PUCCH-ResourceIndex should be
taken from CQI-ReportPeriodic.
For PUCCH
Format 3, one n3PUCCH-AN value out of 4 (n3PUCCH-AN-List-r10)
should be selected based on the TPC field in the DCI format of the
corresponding PDCCH on the SCell.
Similarly, for
PUCCH Format 1b with channel selection, one n1PUCCH-AN value out of 4
(n1PUCCH-AN-CS-List) should be
selected based on the TPC field in the DCI format of the corresponding PDCCH on
the SCell. If Transmission Mode on the SCell is either TM1 or TM2 then n1PUCCH_j
is sufficient, but if TM3 or TM4 is used for the SCell, then n1PUCCH_j+1 should also be provided.
For PUCCH
formats which transmits HARQ feedback for a PDSCH transmission on the primary
cell where there is not a corresponding PDCCH detected (SPS case), instead of nCCE and n1PUCCH-AN, N1PUCCH-AN-Persistent
should be used. It is one value out of 4 N1PUCCH-AN-PersistentList which is based on TPC
command received in the DCI format indicates a semi-persistent downlink scheduling
activation.
