Publication number: 20220352943Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing dynamic beamforming in control channels, by transmitting downlink control channels to user equipment (UEs) in a number of orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A first OFDM symbol of the number of OFDM symbols can be transmitted using first beamforming parameters in a first direction, and a second OFDM symbol of the number of OFDM symbols can be transmitted using second beamforming parameters different from the first beamforming parameters and in a second direction different from the first direction. The number of OFDM symbols used, as well as other parameters, can be dynamically adjusted in subsequent subframes. Other embodiments are described.Type: ApplicationFiled: July 7, 2022Publication date: November 3, 2022Inventors: Huaning Niu, Hyejung Jung, Gang Xiong, Yushu Zhang, Hooman Shirani-Mehr, Yuan Zhu, Jong-Kae Fwu

Patent number: 10958386Abstract: Devices and methods of providing symmetric UL and DL ACK/NACKs is generally described. UL ACK/NACKs of different UEs are multiplexed and received by a UE with a PUSCH. The receiving UE in response transmits the DL ACK/NACK. The ACK/NACK may be transmitted in a localized or distributed manner among subbands that may be adjacent or each may have blocks separated by blocks of a different subband. The ACK and NACK may use independent resources or the NACK may not be transmitted on the single ACK/NACK resource, the lack of an ACK serving as a NACK. The ACK/NACK may be transmitted using a beamforming weight shaped by the received PUSCH/PDSCH. The ACK/NACK symbol may be located in the first symbol, adjacent to the PUSCH/PDSCH, or at the end of a TTI. If adjacent, the UL grant or UL assignment may indicate whether the ACK/NACK resource is used by the PUSCH/PDSCH.Type: GrantFiled: May 9, 2019Date of Patent: March 23, 2021Assignee: Apple Inc.Inventors: Gang Xiong, Huaning Niu, Hooman Shirani-Mehr, Yushu Zhang, Yuan Zhu

Publication number: 20170279292Abstract: Wireless charging, such as that conducted according to various industry standards for wireless charging, can be conducted by magnetic resonance (MR) and/or magnetic induction (MI). Systems, devices, and methods herein provide management of dual mode recharging where a power transmitter unit (PTU) can provide power to charge a power receiver unit (PRU) by MR, MI or both MR and MI. To management the dual mode recharging, the PTU completes handshakes for both modes then determines the abilities of the PRU. Based on the PRU, the PTU selects the MR mode, the MI mode, or a dual mode (using both MR and MI charging). In dual mode, the PTU can use MR and MI charging simultaneously or alternate between the MR and MI modes.Type: ApplicationFiled: March 28, 2016Publication date: September 28, 2017Inventors: Hooman SHIRANI-MEHR, Ahmad KHOSHNEVIS
