Abstract: Embodiments are provided for uplink measurement based mechanism and control using user equipment (UE) centric sounding signals. The mechanism provides an alternative to DL-measurement dominated system control. Based on UL-measurements at TPs, the network obtains knowledge of users' channel and timing information, traffic, and interference, and is thus able to perform better control, including TP and UE clustering and optimization, and power control and link adaptation. In an embodiment method, a TP receives one-to-one mapping information indicating a plurality of UE IDs and a plurality of sounding channels assigned to the corresponding UE IDs. When the TP detects a sounding reference signal (SRS) from a UE, the TP is able to identify the UE using the detected SRS and the one-to-one mapping information. The TP then obtains measurement information for the identified UE, enabling better control and communications for uplink and downlink transmissions between multiple TPs and the UE.

Abstract translation: 提供实施例用于基于上行链路测量的机制和使用用户设备（UE）中心的探测信号的控制。 该机制提供了DL-测量主导系统控制的替代方案。 基于TP上的UL测量，网络获得用户信道和定时信息，流量和干扰的知识，从而能够执行更好的控制，包括TP和UE聚类和优化，以及功率控制和链路自适应。 在一个实施方式中，TP接收指示多个UE ID和分配给相应UE ID的多个探测信道的一对一映射信息。 当TP从UE检测到探测参考信号（SRS）时，TP能够使用检测到的SRS和一对一映射信息来识别UE。 TP然后获得所识别的UE的测量信息，使得能够对多个TP和UE之间的上行链路和下行链路传输进行更好的控制和通信。

Abstract: A communication service manager (CSM) apparatus for monitoring a communication network is provided. The CSM receives configuration instruction message from a higher-level device, and creates or modifies a set of tasks based on the configuration instruction message. The CSM is thus configured to interact with data provider devices to obtain specific information, process the information, and report the results of the processing operations toward a specified device or database. The data provider devices monitor network operations and may include network functions and data analytics manager (DAM) functions. A format for configuration instruction messages, for configuring the CSM, is also provided.

Abstract: The present invention facilitates efficient and effective power management for wireless telecommunications. In one embodiment, presented approaches enable power savings in devices with a limited power supply (e.g., mobile devices operating on battery power supply, photocell, etc.). In one exemplary implementation, power smart channels facilitate power conservation. Power smart channel communications can be transmitted at lower power levels than conventional or normal channel communications. Presented power smart channel methods and systems can be implemented in a wireless cellular communication environment where power smart channels are established and used in accordance with various aspects and configurations of the components (e.g., location, remaining battery charge, multiple resource bands, etc.) in the wireless cellular communication environment.
