Abstract: Enhanced techniques may be used for identifying and reporting collision-based scenarios. In one example, a wireless modem measures a number of signals received from a number of devices that are located on the same chip as the wireless modem when a physical link between the wireless modem and an accelerometer is broken, the accelerometer is inoperable, or a combination thereof. In the event of a collision event, the wireless modem may use the measured signals to determine that the collision event has occurred and may transmit an indication of the collision event. For instance, the wireless modem may use signals from an audio sensor, a motion sensor, a global navigation satellite system (GNSS), or the like.

Abstract: A multi-antenna device configured for addressing connection performance issues in UL/DL imbalance scenarios is described. The device may identify a potential UL/DL imbalance scenario and select signal measurements associated with either a primary antenna or a diversity antenna for mobility procedures and/or mobility measurement reporting based on the detected imbalance. In one example, the device may receive a signal at both the primary and a diversity antenna and may identify an imbalance between the primary and diversity signal measurements. The device may then compare the identified imbalance with an imbalance threshold and may select the primary or diversity signal measurement for mobility procedures and/or measurement reporting based at least in part on the comparison. For instance, if the imbalance is greater than the imbalance threshold the device may use the primary signal measurements and may otherwise use the stronger of the primary or diversity signal measurements.

Abstract translation: 描述了配置用于解决UL / DL不平衡情况下的连接性能问题的多天线设备。 该设备可以识别潜在的UL / DL不平衡场景，并且基于检测到的不平衡来选择与主天线或用于移动性过程和/或移动性测量报告的分集天线相关联的信号测量。 在一个示例中，设备可以在主天线和分集天线两者处接收信号，并且可以识别主要和分集信号测量之间的不平衡。 然后，设备可以将所识别的不平衡与不平衡阈值进行比较，并且可以至少部分地基于比较来选择用于移动性过程和/或测量报告的主要或分集信号测量。 例如，如果不平衡大于不平衡阈值，则器件可以使用主信号测量，否则可以使用较强的初级或分集信号测量。
