SLIV defines the start symbol and the number of consecutive symbols for PDSCH allocation using Single Number.

SLIV = ((L-1)≤7)?(14*(L-1) + S):(14(14-L+1) + (14-1-S))

PDSCH/PUSCH mapping type in the above table is specified in RRC message as shown below.

PDSCH-TimeDomainResourceAllocation ::=      SEQUENCE {

    k0                                  INTEGER (1..3)

    mappingType                         ENUMERATED {typeA, typeB},

    startSymbolAndLength                BIT STRING (SIZE (7)) // SLIV

}

PUSCH-TimeDomainResourceAllocation ::=  SEQUENCE {

    k2                                  INTEGER (0..7)                          

    mappingType                         ENUMERATED {typeA, typeB},

    startSymbolAndLength                BIT STRING (SIZE (7)) // SLIV
