A.8 V2X reference measurement channels

36.1013GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Release 18TSUser Equipment (UE) radio transmission and reception

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.8.1.1 Overview of V2X reference measurement channels

In Table A.8.1.1-1 are listed the Sidelink reference measurement channels specified in annexes A.8.2 to A.8.6 of this release of TS 36.101. This table is informative and serves only to a better overview. The reference for the concrete reference measurement channels and corresponding implementation’s parameters as to be used for requirements are annexes A.8.2 to A.8.6 as appropriate.
