Publication number: 20240049223Abstract: Apparatuses, systems, and methods for cancellation and/or replacement of PUSCHs. A user equipment device (UE) may configure a first PUSCH and a second PUSCH, where the first PUSCH may correspond to a configured grant and where the second PUSCH may correspond to a configured grant or scheduled by a PDCCH on a serving cell. The UE may determine that at least one transmission occasion associated with the first PUSCH overlaps in time with at least one transmission occasion associated with the second PUSCH. The UE may drop transmissions scheduled for the second PUSCH, e.g., based on determining that a priority of the first PUSCH is higher than a priority of the second PUSCH, e.g., starting with a first symbol of a repetition of the second PUSCH which overlaps in time with one or more repetitions of the first PUSCH.Type: ApplicationFiled: October 16, 2023Publication date: February 8, 2024Inventors: Weidong Yang, Ruoheng Liu, Amir Aminzadeh Gohari, Narayan Vishwanathan, Sigen Ye, Chunxuan Ye, Wei Zeng, Dawei Zhang, Oghenekome Oteri

Patent number: 11251913Abstract: A method for controlling a bandwidth used for processing a baseband transmit signal by a transmit path of a transmitter is provided. The method includes generating a first comparison result by comparing, to a threshold value, a first number of physical resource blocks allocated to the transmitter for a first transmission time interval. Further, the method includes generating a second comparison result by comparing, to the threshold value, a second number of physical resource blocks allocated to the transmitter for a subsequent second transmission time interval. The method additionally includes adjusting the bandwidth based on the first and the second comparison results.Type: GrantFiled: September 28, 2017Date of Patent: February 15, 2022Assignee: INTEL CORPORATIONInventors: Rainer Dirk Kreienkamp, Stefan Kaehlert, Giuseppe Li Puma, Markus Hammes, Thorsten Clevorn, Jan Ellenbeck, Tobias Scholand, Matthias Malkowski, Narayan Vishwanathan, Chandra Gupta, Markus Schlamann, Romeo Lopez Soto, Lijun Zhang

Patent number: 10925010Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), and methods are described for generating an extended power headroom report (ePHR) based on an uncertainty associated with a physical downlink control channel communication granting an uplink grant for a physical uplink shared channel communication when the system is configured for simultaneous physical uplink shared channel and physical uplink control channel communications. Some embodiments are structured to generate the ePHR using a type 2 report regardless of the uncertainty associated with the ePHR, while other embodiments generate the ePHR using a reference format. In some embodiments, a UE communicates a timing field with a UE capability communication indicating whether the UE meets timing requirements to avoid uncertainty in ePHR communications.Type: GrantFiled: January 9, 2019Date of Patent: February 16, 2021Assignee: Apple Inc.Inventors: Narayan Vishwanathan, Yujian Zhang, Hong He, Seunghee Han, Youn Hyoung Heo

Patent number: 9876659Abstract: An interference estimation method and a communication device configured to estimate interference. The interference estimation method can include determining a first communication channel of a first uplink communication signal of a first communication protocol and determining a second communication channel of a second downlink communication signal of a second communication protocol. The method can further include: determining frequency spacing between the first uplink communication signal and the second downlink communication signal; determining the PSD of the transmit signal within the receiver bandwidth of the second downlink communication signal; and determining the transmit noise floor from the first uplink communication signal in the receiver bandwidth. Power integration terms can be determined based on the overall PSD of the transmit signal from first uplink communication signal within the second downlink communication channel.Type: GrantFiled: June 25, 2015Date of Patent: January 23, 2018Assignee: Intel CorporationInventor: Narayan Vishwanathan

Patent number: 9055449Abstract: A channel sounding scheme is presented herein that relies on a combination of a first channel sounding procedure and a second channel sounding procedure. The first channel sounding technique is one that involves an exchange of dedicated channel sounding related signals to determine channel conditions between the first wireless communication device and the particular second wireless communication device. The second channel sounding technique is one in which channel conditions are implicitly discovered from any signals transmitted by the particular second wireless communication device to the first wireless communication device. A first wireless communication device computes updates to steering matrix information used for beamforming one or more signal streams to a particular second wireless communication device based on a combination of the first channel sounding technique and the second channel sounding technique.Type: GrantFiled: December 3, 2012Date of Patent: June 9, 2015Assignee: Cisco Technology, Inc.Inventors: Matthew A.
