The second position is not comprising the first DMRS and position not adjacent with the first DMRS.
In practical applications, the specific implementation of such situation are as follows: will be mapped to comprising a CBG of most CB
Include or close on the position of pre-pilot, then divide CBG that other include most CB numbers, finally divides a with other CB
Several CBG, it is also necessary to which explanation, the division of CBG are carried out according to time domain sequence, wherein what described time domain sequentially referred to
It is the sequence of OFDM index from low to high.
For example, when pre-pilot include two OFDM symbols, CBG grouping according to CBG1 and CBG2 include 3 CB, CBG3 and
CBG4 includes 2 CB, in such cases CBG putting in order as shown in Figure 4 in time-domain resource.
Specifically, when the pilot frequency mode be there are when two DMRS, it is described according to the pilot frequency mode, in shared channel
The specific implementation of the position of the upper each CBG of determination are as follows:
The first CBG in first kind CBG is divided in the position comprising the 2nd DMRS；
Wherein, the first CBG is the largest number of CBG of CB in all CBG.
Further, in the 2nd CBG or the second class CBG that the position comprising the first DMRS divides in first kind CBG
