In this paper, we investigate the scheduling scheme to combine cooperative diversity (CD) and multiuser diversity (MUD) in multiuser cooperative networks under the time resource allocation (TRA) framework ...
Based on this TRA framework, a user selection based low complexity relay protocol (US-LCRP) is proposed to combine CD and MUD. ...

The problem of interference in MIMO systems is too large in scope to be handled with a single technique: in practice a combination of complementary countermeasures will be needed. ...
Transmit and receive diversity is generally considered a more conservative approach; a well-known example is space-time codes [1, 2], which have found wide adoption in third-generation (3G) code-division ...

Multiuser multiple-input multiple-output (MIMO) systems are a prime candidate for use in massive connection density in machine-type communication (MTC) networks. ...
In this paper, we propose a user cooperation-based limited feedback strategy to support high connection density in massive MTC networks. ...
Unless a massive number of users are active in the mMTC network, the cooperative feedback strategy might not be an effective solution because the multiuser diversity gain is highly limited in a small-user ...
