Patent number: 11889559Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for channel sensing with self-interference awareness for unlicensed band. A node may transmit, via a first entity of the node, at least one signal during a LBT procedure of a second entity of the node. The at least one signal may include a signal energy. The LBT procedure may be associated with a total measured interference from all detected energy sources. The node may determine a self-interference at the second entity of the node based on the signal energy of the at least one signal transmitted via the first entity of the node and calculate an interference from at least one other source based on a difference between the total measured interference from all detected energy sources and the self-interference determined based on the signal energy of the at least one signal.Type: GrantFiled: April 6, 2021Date of Patent: January 30, 2024Assignee: QUALCOMM IncorporatedInventors: Jianghong Luo, Xiaoxia Zhang, Jing Sun, Navid Abedini, Naeem Akl, Tao Luo, Luca Blessent, Junyi Li, Karl Georg Hampel

Patent number: 11838928Abstract: An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.Type: GrantFiled: October 31, 2019Date of Patent: December 5, 2023Assignee: QUALCOMM IncorporatedInventors: Jianghong Luo, Navid Abedini, Muhammad Nazmul Islam, Luca Blessent, Tao Luo, Junyi Li, Karl Georg Hampel
