The C/I calculation in UL is calculated so that C(j,k) is the received power from the UE_j,k at the j-th BS.

Unit

body	$C(j,k)={{P}_{t}}(j,k)\times effective\_pathloss(U{{E}_{j,k}},B{{S}_{j}})$

(Eq. 54)

where P_t is the transmit power of the UE in dBm (see UL Power control below) and effective_pathloss is defined as in Section ‎7.6.1..

The total interference to a UL cellular system is derived from

body

I(j,k)={{I}_{i\text{nter}}}(j,k)+{{I}_{ext}}(j,k)+N

(Eq. 55)

where

I_inter is the interference coming from UEs of the same system but from adjacent cells, i.e. the inter-system interference from other cells. Since a fully orthogonal system is assumed, only UEs which transmit in the same frequency subcarriers will introduce interference to each other, hence only UEs in other cells with the same k index are considered;
I_ext(j,k) is the interference from external interfering system(s) in adjacent channel;
N is the noise floor.

(Eq. 57)

I_ext(j,k) is the interference to the the victim BS_j from N interfering link transmitters (ILT), where

at the victim system frequency. Where N_RB is the number of RBs (i.e. subcarriers) requested per UE, and M is the maximum number of RBs per BS.
