A.8.1 General
The algorithm for determining the payload size A is as follows; given a desired coding rate R and radio block allocation NRB
1. Calculate the number of channel bits Nch that can be transmitted during the first transmission of a given sub-frame.
2. Find A such that the resulting coding rate is as close to R as possible, that is,
,
subject to
a) A is a valid TB size according to section 7.1.7 of TS 36.213 [6] assuming an allocation of NRB resource blocks.
b) C is the number of Code Blocks calculated according to section 5.1.2 of TS 36.212 [5].
3. If there is more than one A that minimizes the equation above, then the larger value is chosen per default and the chosen code rate should not exceed 0.93.
A.8.2 Reference measurement channel for receiver characteristics
For V2V side link transmission over PC5, Table A.8.2-1 is applicable for measurements on the Receiver Characteristics (clause 7) with the exception of Maximum input level (subclause 7.4G). Table A.8.2-2 and Table A.8.2-3, are applicable for Maximum input level (subclause 7.4G).
