As far as i know, ROHC has got no relation with sub frame number, it just compress the header of IP packets.
Is it correct, spatial diversity is used by MIMO implicitly ? or both are independent to each other.
I saw a radio frame image which was consists of 10 sub frames. Each sub frame was showing PHICH and PCFICH. I know use of these two channels but want to know whether their positions are fixed or varies in each sub frame ?
We know LTE scheduler works at the 1 millisecond level . Why it does not work at the 0.5 ms (slot) level ?
I mean to say, why does MIB transmit only on sub frame 0 not on other sub frames of same radio frame ?
