5A.2.3a Training sequences for dedicated carrier MBSFN
25.2213GPPPhysical channels and mapping of transport channels onto physical channels (TDD)Release 17TS
When the entire carrier is dedicated to MBSFN, preamble is used for the training sequences in each timeslot. In this case, for all timeslots employing MBSFN operation, only a single preamble is needed, i.e. KCell=1, then all physical channels in such timeslots employ the same preamble with the same allocation strategies.
For dedicated carrier MBSFN, the preamble has a fixed length of Lp=96, and the generation of preamble is the same as in the 1.28 Mcps TDD cf. [5A.2.3 Training sequences for spread bursts], which is corresponding to:
K=1, 
, P=64
Note: that 
denotes the largest integer number less or equal to x.
The preamble is generated from one of the basic preamble codes shown in table AA.1a.
The mapping of these Basic Preamble Codes to MBSFN Cell Parameters is shown in [8].
