Publication number: 20190013911Abstract: According to an aspect, a radio access network node supports the transmission of multi-user superposition transmissions, where multi-user superposition transmission comprises transmitting, in each of a plurality of time-frequency resource elements, a modulation symbol intended for a first UE and a modulation symbol intended for a second UE, using the same antennas and the same antenna precoding. The radio access network node receives multiple CSI reports from the first UE for a first reporting instance. One or more of the received multiple CSI reports correspond to one or more respective multi-user superposition transmission states. The radio access network node also determines whether to use multi-user superposition transmission or an orthogonal multiple access transmission for scheduling the first UE in a first scheduling interval, based on the received multiple CSI reports.Type: ApplicationFiled: August 15, 2016Publication date: January 10, 2019Applicant: Telefonaktiebolaget LM Ericsson (publ)Inventors: Siva Muruganathan, Mattias Frenne, Shiwei Gao, Robert Mark Harrison, Bo Lincoln, Zhang Zhang

Publication number: 20180332575Abstract: Systems and methods are disclosed herein that relate to the use of signals in a licensed spectrum to assist with determining a status of an unlicensed channel(s) in an unlicensed spectrum. In some embodiments, a method of operation of a wireless device in a wireless system in which the wireless device transmits and/or receives in both a licensed spectrum and an unlicensed spectrum comprises attempting to detect a busy indication transmitted in the licensed spectrum. The busy indication is an indication that another wireless device is transmitting in the unlicensed spectrum. The method further comprises determining whether to transmit in the unlicensed spectrum based on whether the wireless device has detected a busy indication transmitted in the licensed spectrum. By using signals in the licensed spectrum, the hidden node problem and/or the exposed node problem in the unlicensed spectrum can be mitigated.Type: ApplicationFiled: October 31, 2016Publication date: November 15, 2018Inventors: Gabor Fodor, Bo Lincoln, Häkan Björkegren, Jonas Kronander, Anders Wallén, Fredrik Gunnarsson

Patent number: 9768989Abstract: A simplified but accurate soft-symbol determination process represents one of the advantages provided by the example embodiments disclosed herein. In this regard, a mapping function “maps” symbol estimates to corresponding soft symbol values, which may be used in interference mitigation, joint detection processing, etc. Whether the mapping function is implemented on-the-fly as a live calculation or is embodied in a look-up table, it advantageously operates on the symbol estimates directly, rather than requiring the derivation of corresponding soft bit values or the like, and it maps each symbol estimate to its “expected value,” i.e., the weighted sum of constellation point probabilities. Moreover, the mapping function may be changed dynamically—e.g., by using different look-up tables—to account for changing reception conditions and/or different modulation schemes or other signal parameters associated with the symbols being estimated and mapped to soft symbol values.Type: GrantFiled: May 7, 2013Date of Patent: September 19, 2017Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Bo Lincoln, Fredrik Nordström, Andres Reial
