Publication number: 20240155480Abstract: An apparatus that is in idle mode and registered to a first radio access technology network and to a second radio access technology network may camp on a cell which is one of cells linked for spectrum sharing. The cells linked comprise at least a cell of a first type and a cell of a second type. When the apparatus is camping on such linked cell and detects a need to transit from the idle state to a connected state, the apparatus selects one of the linked cells, and performs initial access to a cell selected to transit from the idle mode to the connected state. The cell selected may be different than the cell camped on.Type: ApplicationFiled: February 7, 2022Publication date: May 9, 2024Inventors: Navin HATHIRAMANI, Karol SCHOBER

Publication number: 20240137783Abstract: An improved NR-U framework allows a gNB to repeat RLM-RS with the same index over each sub-band of an unlicensed spectrum. For example, a RLM-RS with the same indices are repeated by the gNB over the sub-bands of a wideband channel in an unlicensed spectrum. By monitoring the different sub-bands, a UE may find one or more sub-bands in which the RLM-RS having a particular index is successfully transmitted at a subsequent time.Type: ApplicationFiled: February 23, 2021Publication date: April 25, 2024Inventors: István Zsolt Kovács, Teemu Mikael Veijalainen, Wolfgang Zirwas, Navin Hathiramani

Patent number: 11956748Abstract: A determination is made that a registration attempt by a UE with a cell of a wireless network has failed when the UE is in a current tracking area. The UE updates a first list with indications(s) corresponding to the cell and an indication of the current tracking area, and the UE uses the first list for additional registration attempts. A network node sends, toward the UE, a request for the UE to store information, the storing to be in response to registration attempts by the UE with cells of the wireless network having failed while in corresponding tracking areas. The information is to include indication(s) corresponding to the cells and corresponding indication(s) of the tracking areas for the cells. The network node receives, in response to a successful secure connection having been performed between the wireless network and the UE, the information from the user equipment.Type: GrantFiled: November 30, 2021Date of Patent: April 9, 2024Assignee: Nokia Technologies OyInventors: Navin Hathiramani, Devaki Chandramouli
