An overview of these uplink MIMO schemes is presented, along with their impact on reference signals and DL control signaling, and their link performances are compared.Abstract:
The evolution of LTE uplink transmission toward MIMO has recently been agreed in 3GPP, including the support of up to four-layer transmission using precoded spatial multiplexing as well as transmit diversity techniques. In this article, an overview of these uplink MIMO schemes is presented, along with their impact on reference signals and DL control signaling. Receivers suitable for uplink MIMO are presented, and their link performances are compared.read more

Network of Information (NetInf) - An information-centric networking architecture
TL;DR: The results suggest that a scalable NRS for 10^1^5 and more objects with resolution latencies (well) below 100ms is possible, implying that a global Network of Information that removes the need for today's application-specific overlay solutions is feasible.

Systems and methods for improving uplink transmission properties in a communication network
TL;DR: In this article, a method for improving uplink transmission properties in a communication network is proposed that includes obtaining information indicating an operating scenario of a UE, wherein the UE includes a plurality of antennas and the UE is configured to transmit UL signals using the plurality of antenna; selecting a precoder that is optimized for UL multiple antenna transmission based on at least the indicated operating scenario; and communicating the precoder to the UE.

Single carrier FDMA for uplink wireless transmission
TL;DR: Among the possible subcarrier mapping approaches, it is found that localizedFDMA (LFDMA) with channel-dependent scheduling (CDS) results in higher throughput than interleaved FDMA (JFDMA), however, the PARR performance of IFDMA is better than that of LFDMA.

Limited feedback unitary precoding for spatial multiplexing systems
David J. Love,Robert W. Heath +1 more
TL;DR: This correspondence proposes a quantized precoding system where the optimal precoder is chosen from a finite codebook known to both receiver and transmitter and performs close to optimal unitary precoding with a minimal amount of feedback.

Optimum decision feedback multiuser equalization with successive decoding achieves the total capacity of the Gaussian multiple-access channel
Mahesh K. Varanasi,T. Guess +1 more
TL;DR: The key result of this paper is that the OSD achieves the total capacity of the GMAC at any vertex of the capacity region and is optimum in the sense that it maximizes signal-to-interference ratio for each user.

Interleaved FDMA-a new spread-spectrum multiple-access scheme
TL;DR: A new spread-spectrum multiple- access scheme applicable for both the uplink and the downlink of a mobile radio communications system is proposed, which is termed "interleaved frequency-division multiple-access", which combines the advantages of spread-Spectrum and multicarrier transmission.
