Generate the physical uplink control channel (PUCCH) format 3 symbols for two transmit antenna paths and display the information structure.
Initialize parameters for a UE-specific configuration structure and a channel configuration structure. Generate PUCCH1 symbols and information outputs.
ue.NCellID = 1; ue.RNTI = 1; ue.NSubframe = 0; ue.CyclicPrefixUL = 'Normal'; ue.Shortened = 0; chs.ResourceIdx = [0 3]; [pucch3Sym,info] = ltePUCCH3(ue,chs,);
Because there are two antennas, the symbols are output as a two-column vector, and the
info output structure contains two elements.

ue— UE-specific settings
UE-specific configuration settings, specified as a structure that can contain these fields.
|Parameter Field||Required or Optional||Values||Description|
Integer from 0 to 503
Physical layer cell identity
0 (default), scalar integer
Radio network temporary identifier (RNTI) value (16 bits)
0 (default), nonnegative scalar integer
Cyclic prefix length
0 (default), 1
Option to shorten the subframe by omitting the last symbol,
specified as 0 or 1. If
chs— Channel transmission configuration
Channel transmission configuration, specified as a structure containing these fields.
ResourceIdx— PUCCH Resource Indices
PUCCH Resource Indices, specified as an integer or vector of integers with values from 0 to 549. There is one index for each transmission antenna. These indices determine the cyclic shift and orthogonal cover used for transmission. ().
bits— Coded HARQ-ACK bits
Coded HARQ-ACK bits, specified as a nonnegative integer column
vector of length 48. TS 36.211 ,
Table 5.4-1 specifies the vector length for PUCCH format 3 is Mbit =
bits is expected to be the block of bits b(0)...b(Mbit–1)specified
in TS 36.211 , Section 5.4.2A.
also expected to be generated by performing uplink control information
(UCI) channel coding as described TS 36.212 , Section 184.108.40.206. For PUCCH format 3, UCI includes
encoding of concatenated HARQ-ACK bits and any appended periodic CSI
bits plus Scheduling Request (SR) bit when present.
sym— PUCCH format 3 symbols
PUCCH format 3 symbols, returned as matrix. The symbols for
each antenna are in the columns of
the number of columns determined by the number of PUCCH resource indices
Example: [ 0.7071 + 0.7071i,...]
Complex Number Support: Yes
info— PUCCH format 3 information
PUCCH format 3 information, returned as a structure array with elements corresponding to each transmit antenna and containing these fields.
NCellCyclicShift— Cell-specific cyclic shift for each OFDM symbol
Cell-specific cyclic shift for each OFDM symbol, returned as a vector. ()
OrthSeqIdx— Orthogonal sequence index for each slot
Orthogonal sequence index for each slot, returned as a two-element vector. (noc)
Symbols— Modulated data symbols for each OFDM symbol
Modulated data symbols for each OFDM symbol, returned as a vector. (d)
Example: [0.7071 + 0.7071i,...]
OrthSeq— Orthogonal sequence for each slot
Orthogonal sequence of each slot, returned as a numeric matrix. Each column in the matrix contains the orthogonal sequence (wnoc) for each slot.
Example: [1.000 + 1.000i,...]
NSymbSlot— Number of OFDM symbols in each slot
The number of OFDM symbols in each slot, returned as a vector of integers. ()
