Abstract: 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.

Abstract: Embodiments identify a station that rotates an over the air station address. As address rotation was not originally designed into wireless networks, the rotation can introduce communication challenges for the station. The embodiments derive that traffic referencing two different over the air station addresses are associated with a single common station. This is accomplished by determining a similarity between properties of two sets of traffic. A first set of traffic references the first over the air station address and a second set of traffic references the second over the air station address. If the properties common across the two sets of traffic indicate sufficient similarity, the embodiments determine that both sets of traffic are associated with a single device. Network configuration of the device is then adjusted based on the determination.

In some aspects, a user equipment (UE) may determine that a first quantity of physical sidelink feedback channel (PSFCH) transmissions to be transmitted in a slot fails to satisfy a condition that is based at least in part on a maximum quantity of PSFCH transmissions the UE can concurrently detect.
