In some cases, the base station may receive an interference report from a second wireless node, indicating that the first wireless node caused interference at the second wireless node. The base station may transmit a beam tapering configuration of the one or more beam tapering configurations to the first wireless node, and the first wireless node may transmit a beamformed message to the base station according to the beam tapering configuration. In some cases, the beam tapering configuration may be associated with less interference when transmitting the beamformed message.Type: GrantFiled: January 16, 2023Date of Patent: September 10, 2024Assignee: QUALCOMM IncorporatedInventors: Igor Gutman, Navid Abedini

Patent number: 12040816Abstract: A number of unit cells of a digital-to-analog converter (DAC) may be simultaneously activated to generate an analog signal according to a decoded digital signal. However, while many unit cells may be generally the same, there may be variations in the gains associated with each unit cell (e.g., based on the locations of the activated unit cells within a unit cell array) amounting to a gain gradient that may cause error in the analog output. As such, a fill order may be set or selected to counter such variation by activating a particular arrangement of unit cells, as opposed to simply the number of unit cells, for a given digital signal. By filling the unit cell array from different sides, spatially and/or temporally, the gain gradient associated with the unit cells may be balanced to reduce error and increase the linearity of the DAC.Type: GrantFiled: June 17, 2022Date of Patent: July 16, 2024Assignee: Apple Inc.Inventor: Antonio Passamani
