TL;DR: In this article, based on the overview of network coupling structure between radio access technologies, the concept of joint radio resource management built onto the reference structure is introduced and a joint scheduling mechanism allowing traffic to be split over a tightly coupled radio network supported by an adaptive radio multihoming approach is deliberately discussed.

TL;DR: A practical approach using space-frequency-selective multiuser MIMO scheduling that increases the probability of using multistream transmission and has implemented essential functions of the approach in real time on an experimental 3GPP LTE prototype in 20 MHz bandwidth.

TL;DR: In this article, a method and a system for transmitting data by a transmitter over a channel having a predetermined channel quality estimate, comprises the steps of splitting (S2P) input data stream (S40, S60, S80) to be transmitted into a plurality of data sub-streams (S 40a, S40b, S 40c); processing (SYM1, SYM2, SYmj) each of the plurality of substreams into a certain scheme of coded-modulation (S41, S42, S43) by selecting

TL;DR: First multi-hop relaying field trials in the LTE downlink show that outdoor relaying is a key concept to deliver high data rates to the cell edge and provides cell-edge users with a minimum data rate which is mandatory, especially if QoS constraints have to be met.

TL;DR: In this article, an antenna arrangement for transmitting and/or for receiving electromagnetic radiation is described, which includes two antenna elements, which are adapted for transmitting/receiving electromagnetic radiation of a first polarization, and one coupling unit, which is adapted to couple, based on an appropriate control signal.
