Patent number: 11882477Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may identify a conflict between sidelink messages in one or more sidelink resources of a set of sidelink resources reserved for communications by a second UE. In response to identifying the conflict, the first UE may measure a system load of a sidelink channel for the sidelink messages and may determine a threshold system load of the sidelink channel based on one or more priorities associated with the conflicting sidelink messages. If the system load satisfies the threshold system load, the first UE may transmit a message that indicates the conflict. Additionally, or alternatively, the first UE may transmit the conflict indication using a resource determined based on whether one or more of the conflicting sidelink messages are a broadcast sidelink message or a groupcast sidelink message.Type: GrantFiled: January 14, 2021Date of Patent: January 23, 2024Assignee: QUALCOMM IncorporatedInventors: Gabi Sarkis, Tien Viet Nguyen, Sourjya Dutta

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
