Abstract
A wireless access point dynamically controls Device-to-Device (D2D) transmission power. The wireless access point exchanges wireless communications with a plurality of User Equipment (UEs) comprising Device-to-Base Station (D2BS) UEs and D2D UEs, determines geographical locations for each of the D2BS UEs and the D2D UEs, and processes the geographical locations for each of the D2BS UEs and the D2D UEs with a neighbor distance threshold to identify which of the D2BS UEs neighbors the D2D UEs and which of the D2BS UEs do not neighbor the D2D UEs. The wireless access point monitors a Radio Frequency (RF) interference for the neighbor D2BS UEs and the non-neighbor D2BS UEs, determines that a difference between the RF interference of the neighbor UEs and the non-neighbor D2BS UEs is above an RF interference threshold, and transmits an instruction to the D2D UEs neighboring the neighbor D2BS UEs to decrease a transmission power amount.
