Sets a value for the logical root sequence index.
The Logical Root Sequence Index is the value of RACH_ROOT_SEQUENCE which is the logical index for the Zadoff-Chu sequence used for PRACH preamble generation.
There is the relation between the Logical Root Sequence Index and the Physical Root Sequence Index given by Root Zadoff-Chu sequence order table and preamble format.
See the standard document (3GPP TS 36.211) for more information.
Notes) In the case preambles corresponding to Preamble Index cannot be generated from a single root Zadoff-Chu sequence, Logical Root Sequence Index is incremented until corresponding Preamble sequences are found.
That incremented Logical Root Sequence Index is displayed on Logical Root Sequence Index (Incremented) parameter.
Physical Root Sequence Index, Cyclic Shift v and Incremented Logical Root Sequence Index are automatically changed on GUI based on Cyclic Shift Set, Ncs Configuration, Logical Root Sequence Index and Preamble Index.
