Patent number: 11984980Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications network may operate in accordance with an open-RAN (ORAN) network specification which may support functional splitting between the ORAN distributed unit (O-DU) and the ORAN radio unit (RU). The O-DU may communicate with the O-RU using control messaging. The control message may include a resource resource element (RE) mask and a resource symbol mask, the resource RE mask indicating frequency resources to be allocated for a reference signal transmission across a set of antenna ports and the resource symbol mask indicating time resources to be allocated for the reference signal transmission. Additionally or alternatively, the O-DU may transmit a control message including a puncturing resource RE mask indicating frequency resources for applying a puncturing pattern and a symbol mask indicating time resources for applying the puncturing pattern during a transmission.Type: GrantFiled: May 19, 2021Date of Patent: May 14, 2024Assignee: QUALCOMM IncorporatedInventors: Shmuel Vagner, Senthilkumar Sundaram, Abhishek Saurabh Sachidanand Sinha, Orod Raeesi, Roberto Airoldi, Deepak Agarwal

Patent number: 11974223Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support communications. For example, a wireless communications system may support New Radio (NR) cellular-vehicle to everything (C-V2X) communication. In some examples, a user equipment (UE) may receive a sidelink control channel for a sidelink transmission on a first set of symbols of a time slot (e.g., the first two or three symbols of a time slot). The UE may decode the sidelink control channel and disable one or more radio frequency (RF) components associated with processing the sidelink transmission on a second set of symbols of the time slot based on decoding the sidelink control channel. For example, the UE may disable one or more RF components if the UE determines the sidelink control channel is decoded unsuccessfully.Type: GrantFiled: December 16, 2020Date of Patent: April 30, 2024Assignee: QUALCOMM IncorporatedInventors: Cheol Hee Park, Gideon Kutz, Shmuel Vagner, Lior Uziel, Moshe Ben-Ari

Publication number: 20200382922Abstract: A method, apparatus, and computer-readable medium for wireless communication at a first UE, such as C-V2X. The apparatus receives a message comprising a control channel and a data channel from a second UE. The apparatus decodes, at the physical layer, a subset of fields of the control channel. The apparatus determines a priority of the message relative to the first UE based on the subset of fields and determines, at the physical layer, whether to decode the message based on the priority of the message relative to the first UE. The apparatus forwards the message to higher OSI layers for a next stage of decoding when a determination is made at the physical layer to decode the message. The apparatus skips the next stage of decoding of the message at the higher OSI layers when the determination is made at the physical layer not to decode the message.Type: ApplicationFiled: May 13, 2020Publication date: December 3, 2020Inventors: Hee Jun PARK, Assaf TOUBOUL, Shmuel VAGNER

Patent number: 10034305Abstract: Methods, systems, and devices for wireless communication are described. A base station may support layer-to-layer listen-before-talk (LBT) interfacing for logical discontinuous transmission (DTX) events. That is, a layer one entity of the base station may indicate to a higher layer that a channel is unavailable or experiencing high levels of interference. For example, a layer one entity of the base station may perform a failed clear channel assessment (CCA) or LBT procedure on the channel. The layer one entity may then convey an indication that a scheduled message was not successfully transmitted to a higher layer (e.g., a media access control (MAC) layer that performs link adaptation and scheduling). The higher layer may schedule a retransmission of the message based on the indication. In some cases, the same link parameters may be used. In other cases, the link parameters may be updated based on channel conditions.Type: GrantFiled: June 1, 2016Date of Patent: July 24, 2018Assignee: QUALCOMM IncorporatedInventors: Lior Uziel, Guy Wolf, Shmuel Vagner, Yaniv Levi Elgarisi
