Queue-Sharing Multiple Access [PDF]
Queue-Sharing Multiple Access (QSMA) is introduced and analyzed. The new channel-access method consists of establishing and maintaining a distributed transmission queue among nodes sharing a common channel and results in a sequence of queue cycles, with each cycle having one or multiple queue turns with collision-free transmissions from nodes that have

A Novel Downlink IM-NOMA Scheme
In the next generations of communication systems, resources' scarcity devolves to a more critical point as a consequence of the expected massive number of users to be served. Furthermore, the users' contradicting requirements on quality of service forces

Outage Performance Analysis of RSMA-Aided Semi-Grant-Free Transmission Systems
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 ...

On Separation for Multiple Access Channels [PDF]
We examine the issue of separation for multiple access channels. We demonstrate that source-channel separation holds for noisy multiple access channels, when the channel operates over a common finite field.
