Abstract: Systems, methods, apparatuses, and computer program products for asset tracking joint sounding reference signal (SRS) transmission. A location management network node may send a positioning failure message to a serving network node. The serving network node may group devices if one or more criteria are met. When one or more of the devices can be grouped, the serving network node may assign and distribute, to devices, a multi-tag-SRS sequence identifier that may be used by the devices in the group. The serving network node may compute and send, to the devices in the group, a multi-tag-SRS transmit configuration. The devices may perform a joint SRS transmission. The location management network node may compute a location of a centroid for the group of devices associated with the reported metric.

Abstract: Various communication systems may benefit from selectively monitoring alternative links. In certain example embodiments, an apparatus may comprise at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to determine that at least one obstacle has entered at least one predefined region and transmit to at least one network entity at least one indication comprising at least one predicted-power back off (P-PBO) value. The at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to generate at least one predictive-PBO report (P-PBOR) and transmit the at least one P-PBOR to the at least one network entity.
