Patent number: 12142147Abstract: Various aspects of the disclosure relate to a request-response mechanism for sharing sensor information. For example, sensor devices (e.g., in vehicles, fixed structures, or a combination thereof) may selectively share information acquired by the sensor devices. The disclosure relates in some aspects to avoiding redundant transmissions of sensor information. For example, a sensor device of a set of sensor devices may determine which sensor device should transmit information and/or the time(s) at which that sensor device should transmit the information.Type: GrantFiled: September 16, 2021Date of Patent: November 12, 2024Assignee: QUALCOMM IncorporatedInventors: Sudhir Kumar Baghel, Shailesh Patil, Junyi Li

Patent number: 12137371Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., vehicle-to-everything (V2X) systems), a source user equipment (UE) may multicast a data packet to surrounding UEs. In some cases, a receiving UE may fail to receive the transmission due to blocking, shadowing, or interference. The receiving UE may multicast a message requesting retransmission of the packet. Any surrounding UEs that successfully received the data packet from the source UE and the relay request message from the receiving UE may determine whether to relay the packet. Determining whether to relay the packet may be based on a reference signal received power (RSRP) threshold, available resources, a distance to the blocked UE, or some combination thereof. In some examples, the receiving UE may successfully receive the relayed packet from the relay UE even if a path between the receiving UE and the original source UE is blocked.Type: GrantFiled: March 12, 2020Date of Patent: November 5, 2024Assignee: QUALCOMM IncorporatedInventors: Tien Viet Nguyen, Sudhir Kumar Baghel, Kapil Gulati, Arjun Bharadwaj

Patent number: 12068857Abstract: Disclosed are techniques related to performing wireless sidelink communication. Originating (e.g., transmitting) and target (e.g., receiving) apparatuses may operate in a NACK-only mode. In this mode, the target apparatus only provides NACK feedbacks to transmissions that it did not receive. Lack of NACK feedback is interpreted by the originating apparatus that the transmissions were successfully received. However, the target apparatus maybe incapable of transmitting NACK for each of missed transmission. In NACK-only mode, the originating would not retransmit these missed transmissions. To address this issue, the target apparatus can transmit a multi-transmission NACK feedback to indicate that multiple transmissions were not successfully received. The multi-transmission NACK is a single feedback, and thus can enable a target apparatus with limited feedback capacity to indicate NACK for multiple transmissions.Type: GrantFiled: July 28, 2020Date of Patent: August 20, 2024Assignee: QUALCOMM IncorporatedInventors: Gabi Sarkis, Tien Viet Nguyen, Kapil Gulati, Sudhir Kumar Baghel, Shuanshuan Wu
