Patent number: 11974362Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for determining resources for scheduling side-link communications. The resources may be semi-persistent and/or dynamic resources. A user equipment device (UE) may determine a resource map for use in scheduling semi-persistent resources for side-link communications with at least one wireless node. The UE may transmit a resource map request message indicating preferred resource blocks, where each resource block may be defined by a time and a frequency. The UE may receive a confirmation message that may include a report regarding a set of resource blocks. The set of resource blocks may be from the preferred resource blocks included in the resource map request message. The UE may determine, based, at least in part, on the confirmation message, resource blocks to be used for the side-link communications and initiate the side-link communications using the determined resource blocks.Type: GrantFiled: October 12, 2021Date of Patent: April 30, 2024Assignee: Apple Inc.Inventors: Pengkai Zhao, Dawei Zhang, Fangli Xu, Haijing Hu, Haitong Sun, Sami M.

Patent number: 11792881Abstract: Systems and methods are provided for a user equipment (UE) to perform frequency offset (FO) delta tracking. For an anchor component carrier (CC), the UE wakes up to perform tracking updates on a plurality of successive DRX cycles. For the non-anchor CC, the UE determines a minimum update interval ?tupd, and schedules wake-ups on a first subset of the plurality of successive DRX cycles based on the minimum update interval ?tupd. For the first subset of the plurality of successive DRX cycles with scheduled wake-ups, the UE performs the tracking updates on the non-anchor CC and updates an FO delta between the anchor CC and the non-anchor CC. For a second subset of the plurality of successive DRX cycles without the scheduled wake-ups on the non-anchor CC, the UE applies the FO delta to correct for a frequency error.Type: GrantFiled: September 16, 2021Date of Patent: October 17, 2023Assignee: APPLE INC.Inventors: David Öhmann, Hongbo Yan, Amir Farajidana, Dietmar Gradl, Sami M.
