From: Performance analysis and optimization for non-uniformly deployed mmWave cellular network
Symbol and parameter | Description |
|---|---|
A k | The probability that a typical user receives the maximum received power from a k-tier BS. |
r k | The distance from UE to the nearest k-tier BS. |
P k | The transmission power of k-tier BS. |
P k | The directivity gain of a k-tier link. |
α k | The path loss exponent in the k-th tier. |
Pr,k(rk) | The long-term received power from a k-tier BS at UE. |
\({F_{{R_{l}}}}\left ({r_{l}} \right)\) | The cumulative distribution function (cdf) of the distance to the nearest l-tier BS. |
\({f_{{X_{k}}}}\left ({x_{k}} \right)\) | The probability distribution function (pdf) of k-tier associated distance xk. |
SINRk(x) | The received SINR at the typical user (at origin o) conditioned on the associated k-tier BS at x. |
\({\mathfrak {R}_{k}}\) | The average achievable rate on the condition that user is associated with k-tier. |
\(\mathfrak {R}\) | The average achievable rate. |
φ sm | The sm-tier coverage probability conditioned on the associated distance. |
φ mu | The mu-tier coverage probability conditioned on the associated distance. |
