… multiple users into multiple groups. In this paper, a EH-based AF hybrid relaying network
with imperfect channel state information (ICSI) is considered, and the impact of user pairing on …

… Also note that as previously mentioned our approach is general and can be extended to
any number of users by randomly pairing up the users. We then assign a timeslot to each …

… )-aided THz networks with imperfect channel state information (CSI). Specifically, we present
… Assuming that the imperfect CSI is available, we can obtain the optimal PS for any pairing, …

… In this section, the offloading outage performance for the paired users under ipCSI/pCSI
conditions in the uplink NOMA-MEC system is analyzed. Firstly, we derive the exact closed-form …

… , a low-complex joint user pairing and power … imperfect CSI. Simulation results show
that the proposed algorithm can achieve desirable throughput performance, and restrict inter-user …

… non-optimal power scheme and the imperfect channel state information (CSI) happen. More
… multi-pair of users, in which group of users can communicate to other users to achieve …

… system under imperfect CSI. Those work all considered the single user MIMO two-way
channel situation, there is no analysis for cellular environments under imperfect CSI condition as …

… For brevity, the random user pairing algorithm is used in this can be modified with new …
Hence, in the imperfect CSI scenario to provide secrecy capacity to the intended user, we propose …

… the reliance of NOMA systems on accurate CSI in achieving multi-user gains. We view this
… In this section, the conventional near-far UE pairing concept in NOMA system is addressed. …

… Several parameters such as user pairing and power allocation algorithms are presented
in downlink of NOMA.3 It is confirmed that the crucial feature such as power allocation, …
