This variation in received power causes some packets to fall below the minimum receive threshold for the data rate being used, and those packets are dropped.
When the received signal power is below the receiving threshold, we believe that there is no wireless link between the two nodes.
Second, the transmit power from MBS to M-UE is PMU, the receive threshold is denoted as ΓMU, and IMU is the aggregate interference from all the other active MBSs except the target MBS m0.
The wireless transmission range r 0 of each node can then be calculated as the equivalent transmission power using a receiving threshold, P rx,th, also referred to as the reception sensitivity.

In this PCCF protocol, the RTS transmitted power is based on the carrier sense threshold, the receiving threshold and the maximum transmitted power, and then the data transmitted power is calculated based on the SINR (signal to interference and noise ratio) threshold.
We assume that R-UEs receiving messages by the aid of RSs are located according to some stationary point process in a circular area around the RS and of radius R. We denote PR as the transmit power of the RS, ΓRU as the receive threshold, and IRU as the sum of interference of all other active RSs except the target RS r0.
Our numerical results indicate that cooperative relaying between the primary and the secondary system can help the secondary network to achieve a higher transmission capacity in some cases, and the capacity gain on cooperative relaying largely depends on the location of the relay, the power ratio, as well as the receiving threshold of the secondary network.
Six networks that had not achieved the "ready to receive" threshold by the final assessment were classified as "other".
For getting analytical and simulation results, we fix various parameters as follows: Path loss constant K = 16.37 × 10-6, received SNR threshold ψ = 10 dB and the total additive noise power W = 1.65 × 10-13 Watts. 10-13 Watts
To achieve the requested C2C C2I 6–7 Mbps bit rate, considered sufficient for vehicle to infrastructure communication [22], a −72 dBm reference input power level was considered as a receiving threshold.
