  • Patent number: 11153272
    Abstract: Embodiments described herein relate to managing bearers in a radio access network (e.g., next generation RAN (NG-RAN), etc.). In one example, a central-unit control-plane (CU-CP) communicates with a distributed unit (DU) and a CU-UP to exchange transport network layer addresses (TNLAs) and tunnel endpoint identifiers (TEIDs) between the DU and the CU-UP. In this way, the DU becomes resistant to the CU-UP's rejection of a bearer setup request from the CU-CP during a bearer setup procedure. Furthermore, during virtual machine (VM) migration or local problems of the CU-UP, an E1 procedure known as “bearer relocate” can be defined to notify the DU of a new TNLA for one or more affected general packet radio service tunneling protocol (GTP) tunnels that are affected by the VM migration or local problems.

    Abstract: A method for analyzing a wireless link (3) of a wireless node of a customer premises equipment (CPE) device (1) during operation of the CPE device comprises: performing an active test, during which a data transmission is forced through the wireless link, to obtain a first set of parameters, and performing before or after the active test a passive test, which is a monitoring ode during which a data transmission of the CPE device is monitored, to obtain a second set of parameters. In particular, based on the first set of parameters, it is determined whether and to which extent the wireless link is in an uncertainty zone, and based on the second set of parameters, the decision is made to assign an observed decrease in a measured data rate to physics effects or to interference effects.

  • Patent number: 11129037
    Abstract: A cross link interference (CLI) measurement system is disclosed. The cross link interference measurement system can measure both unconstrained CLI that do not require any special constraints on the frame structure, and constrained CLI that does require special constraints on the frame structure (e.g., measurement gaps). The system does this in part by not only measuring reference signal received powers, but also determining load based on a power scaling of a reference signal and based on angle of arrival determinations.

  • Patent number: 11039422
    Abstract: To increase network efficiency, a user equipment (UE) can be appointed as a local manager to coordinate the allocation of resources used by other UEs. For example, the network can promote the UE as a local manager and assign the local manager a resource pool. The local manager can then broadcast synchronization signals to let the other UEs associate themselves with the local manager. After the other UEs are synced with the local manager, the local manager can allocate resources to the other UEs. Based on report data regarding the local managers management procedures, the network can maintain the UE as the local manager or demote the UE from local manager status.
