Resource allocation for wireless powered multi-pair two way relay networks
|

|
|
We consider a wireless powered multi-pair two-way relay network in which the devices without batteries communicate with their partners assisted by a hybrid access point (HAP). For the network, half-duplex (HD) and full-duplex (FD) protocols are designed in a time division multiple access manner and power and time allocation problems are addressed. The problems optimize a generalized utility function taking into account the efficiency and fairness under the power constraints at the HAP and the en
