In this paper we analyze the outage and throughput performance of a semi-grant free uplink
based on non-orthogonal multiple access. We assume that the grant based user is selected …

With the exponential increase of the number of devices in the communication ecosystem
toward the upcoming sixth generation (6G) of wireless networks, more enabling …

In this paper, the secondary users (SUs) in a cognitive radio utilizing the power allocation of
Nonorthogonal multiple access is analyzed. In the proposed model, the interference of SUs …

Non-orthogonal multiple access (NOMA) has been recognized as a potential technique to
achieve higher spectral efficiency (SE) for future 5G systems. However, the anticipated …

In this paper, we propose a cognitive radio-inspired rate-splitting multiple access (CR-
RSMA) scheme to assist semi-grant-free (SGF) transmissions in which a grant-based user …

In this article, radio resource allocation in underlay spectrum sharing based on the
orthogonal frequency-division multiple access is studied. A cellular-based secondary …

As a technology that can accommodate more users and significantly improve spectral
efficiency, non-orthogonal multiple access (NOMA) has attracted the attention of many …

In this paper, the power allocation of Nonorthogonal multiple access (NOMA) for secondary
users (SU) in a Cognitive Mobile Radio Network (CMRN) is studied. In the proposed …

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 …

In this paper, we analyze the performance of an underlay downlink non-orthogonal multiple
access (NOMA) network with multiple near and far-users. Different from cognitive radio (CR) …
