Downlink outage performance of heterogeneous cellular networks [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 This paper derives tight performance upper and lower bounds on the downlink outage efficiency of K-tier heterogeneous cellular networks (HCNs) for general signal propagation models with Poisson distributed base stations in each tier. In particular, the proposed approach to analyze the outage metrics in a K-tier HCN allows for the use of general bounded

Outage-constrained resource allocation in uplink NOMA for critical applications [PDF]
, 2017 In this work, we consider the resource allocation problem for uplink non-orthogonal multiple access (NOMA) networks whose users represent power-restricted but high priority devices, such as those used in sensor networks supporting health and public ...

Outage-constrained robust power allocation for downlink MC-NOMA with imperfect SIC [PDF]
, 2018 In this paper, we study power allocation for downlink multi-carrier non-orthogonal multiple access (MC-NOMA) systems and examine the effects of residual cancellation errors resulting from imperfect successive interference cancellation (SIC) on the system

Outage Performance in Secure Cooperative NOMA [PDF]
2019 Iran Workshop on Communication and Information Theory (IWCIT), 2019 Enabling cooperation in a NOMA system is a promising approach to improve its performance. In this paper, we study the cooperation in a secure NOMA system, where the legitimate users are distributed uniformly in the network and the eavesdroppers are distributed according to a homogeneous Poisson point process.

Outage Performance Analysis of RSMA-Aided Semi-Grant-Free Transmission Systems
IEEE Open Journal of the Communications Society, 2023 In this paper, we analyze the outage performance of a rate-splitting multiple access (RSMA)-aided semi-grant-free (SGF) transmission system, in which a grant-based user (GBU) and multiple grant-free users (GFUs) access the base station by sharing the ...

Outage analysis of superposition modulation aided network coded cooperation in the presence of network coding noise [PDF]
, 2015 We consider a network, where multiple sourcedestination pairs communicate with the aid of a half-duplex relay node (RN), which adopts decode-forward (DF) relaying and superposition-modulation (SPM) for combining the signals transmitted by the source ...

Outage probability analysis of vehicular communication system with two-way AF cooperation
Dianzi Jishu Yingyong, 2018 In vehicular communication system, two-way cooperative communication can improve system performance. However, vehicle mobile communication will cause the two-way link correlation and thus reduce the system outage performance.
