What is the Sinr in LTE?

SINR is a measure of signal quality as well but it is not defined in the 3GPP specs but defined by the UE vendor. It is not reported to the network. SINR is used a lot by operators, and the LTE industry in general, as it better quantifies the relationship between RF conditions and Throughput.

Consequently, what is Carrier to Interference ratio?

The signal-to-interference ratio (SIR or S/I), also known as the carrier-to-interference ratio (CIR or C/I), is the quotient between the average received modulated carrier power S or C and the average received co-channel interference power I, i.e. cross-talk, from other transmitters than the useful signal.

What is the best Sinr?

SINR/SNR – The signal-to-noise ratio of the given signal. RSRP – The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm(bad). RSRQ – Indicates quality of the received signal, and its range is typically -19.5dB(bad) to -3dB (good).

What is the co channel reuse ratio?

The channel reuse ratio in a cellular system is defined as the ratio of the distance between cells using related channels to the cell radius . If a pair of terminals in two cells are using the same channel, the ratio is called the cochannel reuse ratio (CRR).
