Patent number: 11882554Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that the first UE is scheduled to transmit in a first slot and a second slot after the first slot. The first UE may then transmit, to a second UE, a first set of data in the first slot based on determining that the first UE is scheduled to transmit in the first slot and the second slot. In some examples, the first UE may determine whether a power estimation capability of the second UE satisfies a threshold. In some cases, the power estimation capability may be based on a correspondence between transmissions in the first slot and expected transmissions in the second slot. Based on the power estimation capability of the second UE, the first UE transmits data in a symbol reserved for automatic gain control at the second slot.Type: GrantFiled: June 23, 2020Date of Patent: January 23, 2024Assignee: QUALCOMM IncorporatedInventors: Kapil Gulati, Aamod Khandekar, Shailesh Patil, Shuanshuan Wu, Tien Viet Nguyen, Sudhir Kumar Baghel, Arjun Bharadwaj

Publication number: 20230217221Abstract: Methods, systems, and devices for wireless communications are described that may enable a user equipment (UE) to transmit sidelink data within an interference avoidance resource scheduling scheme. For example, a UE may determine to segment a data packet for transmission in a vehicle-to-everything (V2x) system (e.g., to ensure that each segment fits within one transmission time interval (TTI)). In some cases, a UE may identify a data packet for transmission, may determine that the size of the data packet exceeds a threshold size, may segment the data packet to ensure each segment fits within one TTI, and may transmit the data packet segments (e.g., to additional UEs), where said transmissions may be discontinuous. In some examples, a UE may determine to segment the data packet and then encode the data packet. Additionally or alternatively, the UE may determine to encode the data packet and then segment the data packet.Type: ApplicationFiled: December 27, 2022Publication date: July 6, 2023Inventors: Arjun Bharadwaj, Tien Viet Nguyen, Kapil Gulati, Sudhir Kumar Baghel
