Why resource reservation period is divided by 10? #4

Hi, Thanks for sharing your work. I was having a look at the LteUeMac class, in there you are dividing the m_pRsvp (resource reservation period) by 10. Could you please tell me the reason? Is it as per the 3GPP standard?

Kind regards, Zoraze

Hi, as the mentioned line calculates a frame number, the time to the next transmission calculated by reselection counter * resource reservation period in ms is divided by 10, as 1 frame contains 10 subframes (1ms = 1 subframe).
