Publication number: 20240080154Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a first network entity. The techniques may generally involve generating a message with entries that represent blocks of physical resource blocks (PRBs), for transmitting reference signals over a fronthaul interface using modulation compression; transmitting the message to a second network entity via the fronthaul interface; and processing reference signals, transmitted in the blocks of PRBs on the fronthaul interface using modulation compression.Type: ApplicationFiled: November 10, 2023Publication date: March 7, 2024Inventors: Shmuel VAGNER, Michael Francis GARYANTES, Senthilkumar SUNDARAM, Abhishek Saurabh SACHIDANAND SINHA, Shingyu KWAK, Deepak AGARWAL, James KRYSL

Publication number: 20240063851Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit may output capability information regarding a number of beamforming codebooks supported by the radio unit. The radio unit may obtain configuration information that configures one or more beamforming codebooks for an antenna array of the radio unit. The radio unit may communicate using the one or more beamforming codebooks. Numerous other aspects are described.Type: ApplicationFiled: August 16, 2022Publication date: February 22, 2024Inventors: Abhishek Saurabh SACHIDANAND SINHA, Deepak AGARWAL, Michael Francis GARYANTES, Rohan SALVI, Orod RAEESI, James KRYSL, Senthilkumar SUNDARAM, Kalyan KUPPUSWAMY

Patent number: 11889436Abstract: The transmission and reception group delay in a front end structure of a mobile device may be determined using closed loop calibration. The closed loop may be a near field radiated closed loop between pairs of antennas in an antenna array of the mobile device. The delay based on time of transmission and time of reception may be measured for a plurality of pairs of antennas, from which the transmit and receive group delay within a single path may be determined. The propagation delay of the signal between antennas may be included in the group delay calibration for increased accuracy. In another implementation, a conducted closed loop, e.g., in the transceiver or in a radio frequency switching network may be used to calibrate the group delay. Pre-characterization of the delay caused by components between the closed loop and antennas may be included in the group delay calibration for increased accuracy.Type: GrantFiled: August 17, 2020Date of Patent: January 30, 2024Assignee: QUALCOMM IncorporatedInventors: Jay King, Alexander Dorosenco, Muhammad Sayed Khairy Abdelghaffar, Joseph Binamira Soriaga, Carl Hardin, Alexandros Manolakos, James Krysl, Michael Allen Kongelf, Krishna Kiran Mukkavilli, Tingfang Ji, Joseph Patrick Burke

Publication number: 20230402766Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit (RU) may transmit, to a controller of the RU, a message including an ordered list of coordinates corresponding to a plurality of antenna elements in an antenna array of the RU. The RU may receive, from the controller, an indication of one or more low-level endpoints associated with one or more activated antenna elements of the plurality of antenna elements. Numerous other aspects are described.Type: ApplicationFiled: March 24, 2023Publication date: December 14, 2023Inventors: Michael Francis GARYANTES, Abhishek Saurabh SACHIDANAND SINHA, Christian Oliver THELEN, Senthilkumar SUNDARAM, Orod RAEESI, James KRYSL, Luca BLESSENT, Deepak AGARWAL

Publication number: 20230217422Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit (RU) may receive, from a distributed unit (DU), a control plane message associated with a section type that is dedicated for slot level configuration information. The control plane message may include a common section header that identifies a group of one or more endpoints, and one or more section type commands that include information associated with a slot level common configuration for the group of one or more endpoints. The RU may perform at least one of radio frequency configuration or time domain beamforming for the group of one or more endpoints based at least in part on the information included in the one or more section type commands. Numerous other aspects are described.Type: ApplicationFiled: December 20, 2022Publication date: July 6, 2023Inventors: Abhishek Saurabh SACHIDANAND SINHA, Senthilkumar SUNDARAM, Christian Oliver THELEN, Michael Francis GARYANTES, Deepak AGARWAL, Orod RAEESI, James KRYSL

Publication number: 20220095160Abstract: Aspects relate to provision of a control message, such as an extension data section, that includes an indication of the repeat of highest priority data sections. The control message may be generated in a distributed unit (DU) and conveyed to a radio unit (RU) via a fronthaul link The control message may include either a flag or bits in a field of an extension data section allowing a RU to determine repeat of the highest priority data section based on reception of the flag or processing of the bit value in the field. Additionally, the indication of repetition of the highest priority section may be based on a section identifier transmitted by a DU, wherein an RU receiving the section identifier may determine repeat of the highest priority data section by tracking the received section identifier.Type: ApplicationFiled: September 21, 2021Publication date: March 24, 2022Inventors: Christian Oliver THELEN, Senthilkumar SUNDARAM, Rohan SALVI, James KRYSL, Kenneth David EASTON

Patent number: 7954016Abstract: Embodiments disclosed herein address the need in the art for an efficient multi-symbol deinterleaver. In one aspect, a plurality of memory banks are deployed to receive and simultaneously store a plurality of values, such as soft decision values determined from a modulation constellation, in accordance with a storing pattern. In another aspect, the storing pattern comprises a plurality of cycles, a selected subset of the plurality of memory banks and an address offset for use in determining the address for storing into the respective memory banks indicated for each cycle. In yet another aspect, the stored values may be accessed in order with a sequentially increasing index, such as an address. Various other aspects are also presented. These aspects have the benefit of allowing multiple symbol values to be deinterleaved in an efficient manner, thus meeting computation time constraints, and conserving power.Type: GrantFiled: March 4, 2010Date of Patent: May 31, 2011Assignee: Qualcomm IncorporatedInventors: Hanfang Pan, Inyup Kang, James Krysl
