Fig. 2From: Energy-efficient power allocation for massive M2M communication over LTE-A cellular uplinkThe power consumption with different payloads. The MTCDs are uniformly distributed in 100-m radius of the MTCG, and the MTCG is uniformly distributed in 1000-m radius of the BS. The number of groups of MTCDs is K=10. The other configuration parameters are \(P_{k}^{\max } = 14\) dBm, \(P_{\text {G}}^{\max } = 24\) dBm, T=1 ms, Bk=180 kHz, and BG=KBk=1800 kHzBack to article page
