Virtual full-duplex buffer-aided relaying - Relay selection and beamforming
In this paper, we study virtual full-duplex (FD) buffer-aided relaying to recover the multiplexing loss of halfduplex (HD) relaying in a network with multiple buffer-aided relays, each of which has multiple antennas, through opportunistic relay selection and beamforming. The main idea of virtual FD buffer-aided relaying is that a source and a relay simultaneously transmit their own information ...
متن کاملMutual Information of Buffer-Aided Full-Duplex Relay Channels
We derive the mutual information (MI) of the wireless links in a buffer-aided full-duplex (FD) multiple-input multiple-output (MIMO) relaying network. The FD relay still suffers from residual selfinterference (RSI), after the application of self-interference mitigation techniques. We investigate both cases of the slow-RSI channel, where the RSI is fixed over the entire codeword, and the fast-RS...
متن کاملOpportunistic half-duplex/full-duplex relaying mode selection criterion in cognitive relay networks
In this paper, adaptive transmission in a cognitive relay network where a secondary transmitter acts as cooperative relay for a primary transmitter while in return gets the opportunity to send its own data is considered. An opportunistic half-duplex (HD)/full-duplex (FD) relaying mode selection criterion which can utilize the advantages of both HD and FD is proposed. The key idea is that the co...
متن کاملSpatially Random Relay Selection for Full/Half-Duplex Cooperative NOMA Networks
This paper investigates the impact of relay selection (RS) on the performance of cooperative non-orthogonal multiple access (NOMA), where relays are capable of working in either full-duplex (FD) or half-duplex (HD) mode. A number of relays (i.e., K relays) are uniformly distributed within the disc. A pair of RS schemes are considered insightfully: 1) Single-stage RS (SRS) scheme; and 2) Two-sta...
متن کاملJoint relay-pair selection for buffer-aided successive opportunistic relaying
In this work, we present a buffer-aided successive opportunistic relaying scheme that aims at improving the average capacity of the network when inter-relay interference arises between relays that are selected for simultaneous transmission and reception. We propose a relay selection policy that, by exploiting the benefits of buffering at the relays, decouples the receiving relay at the previous...
