Simple Semi-Grant-Free Transmission Strategies Assisted by Non-Orthogonal Multiple Access
Zhiguo Ding, Robert Schober, Pingzhi Fan +1
Grant-free transmission is an important feature to be supported by future wireless networks since it reduces the signalling overhead caused by conventional grant-based schemes. How…
Closed-Form Word Error Rate Analysis for Successive Interference Cancellation Decoders
Jinming Wen, Keyu Wu, Chintha Tellambura +1
We consider the estimation of an integer vector $\hbx\in \mathbb{Z}^n$ from the linear observation $\y=\A\hbx+\v$, where $\A\in\mathbb{R}^{m\times n}$ is a random matrix with indep…
On the Performance of NOMA with Hybrid ARQ
Donghong Cai, Zhiguo Ding, Pingzhi Fan +1
In this paper, we investigate the outage performance of hybrid automatic repeat request with chase combining (HARQ-CC) assisted downlink non-orthogonal multiple access (NOMA) syste…
Impact of Non-orthogonal Multiple Access on the Offloading of Mobile Edge Computing
Zhiguo Ding, Pingzhi Fan, H. Vincent Poor
This paper considers the coexistence of two important communication techniques, non-orthogonal multiple access (NOMA) and mobile edge computing (MEC). Both NOMA uplink and downlink…
Device Caching for Network Offloading: Delay Minimization with Presence of User Mobility
Tao Deng, Lei You, Pingzhi Fan +1
A delay-optimal caching problem (DOCP) in deviceto- device (D2D) networks with moblity is modelled. The problem arises in the context of achieving offloading using device caching,…
