Patent number: 11265916Abstract: Systems and methods are disclosed herein that relate to the use of a Device-to-Device (D2D) sidelink, e.g., in a licensed spectrum, to assist with clear channel assessment in an unlicensed spectrum. In doing so, the hidden node problem and/or the exposed node problem can be mitigated. In some embodiments, a method of operation of a wireless device in a cellular communications network comprises performing a sidelink-assisted clear channel assessment (SLA-CCA) procedure to determine whether to transmit on an unlicensed channel. The SLA-CCA procedure is a Clear Channel Assessment (CCA) procedure that is assisted by information received by the wireless device from one or more other wireless devices over a D2D sidelink in a licensed spectrum. The method further comprises, upon determining to transmit on the unlicensed channel as a result of performing the SLA-CCA procedure, transmitting a transmission on the unlicensed channel.Type: GrantFiled: October 31, 2016Date of Patent: March 1, 2022Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Gabor Fodor, Håkan Björkegren, Fredrik Gunnarsson, Jonas Kronander, Bo Lincoln, Anders Wallén

Patent number: 10980039Abstract: A radio device performs uplink transmissions on a first carrier. The uplink transmissions on the first carrier require scheduling by a node of a wireless communication network. Further, the radio device performs uplink transmissions on a second carrier. The uplink transmissions on the second carrier require that, by a carrier sense operation, the radio device assesses the second carrier as being unoccupied before proceeding to the uplink transmission on the second carrier. For a certain uplink transmission on the second carrier, the radio device performs the carrier sense operation to assess whether the second carrier is unoccupied and provides an indication of a result of the carrier sense operation to the node which is responsible for the scheduling.Type: GrantFiled: September 29, 2016Date of Patent: April 13, 2021Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Gabor Fodor, Muhammad Kazmi
