On Channel Selection for Carrier Aggregation Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, the problem of sub-channel selection for carrier aggregation (CA) systems is examined. CA enables the achievement of high data rate links via simultaneous transmissions over multiple component carriers. A ...
Distributed power allocation for multi-flow carrier aggregation in heterogeneous cognitive cellular networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, we study distributed power allocation for multiflow carrier aggregation in cognitive cellular networks. Our approach differs from the conventional water filling (WF) algorithm since we deal with heterogeneous ...
Thresholds optimization for one-bit feedback multi-user scheduling
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
We propose a new one-bit feedback scheme with scheduling decision based on the maximum expected weighted rate. We show the concavity of the 2-user case and provide the optimal solution which achieves the maximum weighted ...
Energy-efficient cooperative cognitive relaying schemes for cognitive radio networks
(
Elsevier B.V.
, 2018 , Article)
We investigate a cognitive radio network in which a primary user (PU) may cooperate with a cognitive radio user (i.e., a secondary user (SU)) for transmissions of its data packets. The PU is assumed to be a buffered node ...
