Patent number: 11606132Abstract: The application relates to beam management for a client device in a power saving state. When the client device is in the power saving state, the client device monitors serving beams of a network access node based on a serving beam configuration. The serving beam configuration indicated the serving beams to be monitored by the client device in the power saving state. If the client device detects a beam failure during the serving beam monitoring in the power saving state, the client device performs a beam reconfiguration procedure. The beam reconfiguration procedure informs the network access node about the change in serving beam status and allows the network access node to update the serving beam configuration.Type: GrantFiled: January 27, 2021Date of Patent: March 14, 2023Assignee: Huawei Technologies Co., Ltd.Inventors: Petteri Kela, Mario Costa, Johan Christer Qvarfordt

Patent number: 11418983Abstract: Embodiments of the disclosure relate to a coordinator network node and one or more network access nodes interworking in a wireless communication system. The coordinator network node determines a joint resource allocation area (?UE) based on measurement messages from network access nodes. The determined joint resource allocation area (?UE) is thereafter transmitted to the network access nodes. Thereby, the coordinator network node enables to determine the portion of the first or the second service areas that are free from interference from neighbouring network access nodes where each network access node can perform resource allocations independently. It further enables to determine/identify the joint resource allocation area where neighbouring network access nodes significantly interfere each other. Therefore, e.g. resource allocation in the system can be improved. Furthermore, the disclosure also relates to corresponding methods and a computer program.Type: GrantFiled: October 30, 2020Date of Patent: August 16, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: George Koudouridis, James Gross, Johan Christer Qvarfordt, Kari Juhani Leppanen
