nrPUCCH2

Generate PUCCH format 2 modulation symbols

Description

example

sym = nrPUCCH2(uciCW,nid,rnti) returns the physical uplink control channel (PUCCH) format 2 modulation symbols, as defined in TS 38.211 Section 6.3.2.5 [1]. uciCW is the encoded uplink control information (UCI) codeword, as defined in TS 38.212 Section 6.3.1 [2]. The encoding consists of scrambling using scrambling identity nid and QPSK modulation. rnti specifies the radio network temporary identifier (RNTI) of the user equipment (UE).

example

sym = nrPUCCH2(___,'OutputDataType',datatype) specifies the PUCCH symbol data type in addition to the input arguments in the previous syntax.
