Device-to-device (D2D) communication underlaying cellular networks is expected to bring
significant benefits for utilizing resources, improving user throughput, and extending the
battery life of user equipment. However, the allocation of radio and power resources to D2D
communication needs elaborate coordination, as D2D communication can cause
interference to cellular communication. In this paper, we study joint channel and power
allocation to improve the energy efficiency of user equipments. To solve the problem …

In device‐to‐device (D2D) communication underlaying cellular networks, the D2D user
equipments (DUEs) can communicate by sharing the radio resources assigned to cellular
user equipments. D2D communication is expected to improve the network throughput and
save more energy for the user equipments. However, D2D communication causes severe
interference to both the cellular users and other DUEs which is a challenge to radio resource
allocation. The authors propose joint channel and power allocation algorithm to maximise …
