Is it possible to reduce the impact of this phenomenon?

The question concerns the interference. Why interference occur in the area between the sectors of the same eNB and between eNBs. The result of such interference's is the decrease of SINR and the DL throughput. Such situation is not present in uplink. Is it possible to reduce the impact of this phenomenon?

LTE employs single frequency reuse. The idea is to maximize spectrum usage efficiency as spectrum is the single most expensive element in the network. However since the same spectrum is reused in all cells, therefore interference occurs in the area between the sectors of the same eNB and between eNBs.
By the way interference is not limited to downlink, in fact it occurs in uplink also since the UEs in all the cells are also reusing the frequency in uplink.
Interference is maximum in the cell edges. LTE uses ICIC (Inter Cell Interference Coordination) technique to coordinate resource allocation at the edge of cell and mitigate interference.

LTE Cell Interference: In Lte, how does cell interference control ?

As per my knowledge, LTE technology has frequency reuse factor 1, which means same frequency can be used two or more eNodeBs. As per my knowledge, cell interference can be controlled by using different PCI to each of the neighbor nodes.

I want to know, Are there any other things being used to avoid cell interference in lte technology or just PCI i.e physical cell identity is just enough to avoid cell interference.

Is it possible to optimize this code to reduce number of instructions performing on it? 
int32 find_result(int64 sec)
{

    if(config == defualt_base)
    {
        uint32 H      = j * k + 1; /*(here j and k global)*/

        if((((uint32)(sec - CS - RS)) % (H * N_p * M_r))== 0) 
        {
            result = 0;
        }
    }
    else
    {
        if((((uint32)(sec - CS - RS)) % (N_p * M_r))== 0)  /*(N_p and M_r global)*/
        {
            result = 0;
        }
    }
}

This function have to be execute several times in a second, How can optimize it ? Please help me to avoid mathematical operations applying on this function?

Do we have a better method, capable to inspect each RB?

As we know Per Resource Blocks (RB) SINR from UE report. I know that an UE reports all the RBs SINR as quick as possible (maybe each subframe period, that is 1 ms). I’m thinking of the Higher Layer-configured subband CQI report since it’s the most capable of inspecting the RBs status as I saw in 3GPP 36.213 Table 7.2.1-1. I’m interested in FDD; unfortunately the least “RB contiguous number” is 4 as in Table 7.2.1-3. Do we have a better method capable to inspect each RB?
