  • Publication number: 20210067294
    Abstract: Sparse reference signal-related signaling, for a wireless channel that is associated with multiple antenna ports, is communicated with a User Equipment (UE). The sparse reference signal-related signaling is consistent with a sparse signaling pattern. In an embodiment, the sparse signaling pattern includes reference signal-related signaling associated with each of the antenna ports, and has been determined based on previous reference signal-related signaling previously communicated with the UE or another UE. In another embodiment, the sparse reference signal-related signaling is consistent with a varying sparse signaling pattern that is based on previous reference signal-related signaling previously communicated with the UE or another UE.

    Abstract: Network equipment receives, from a User Equipment (UE), an indication that the network equipment is to transition to sparse reference signaling for the UE, and the network equipment then transmits the sparse reference signaling to the UE. The sparse reference signaling is consistent with a sparse signaling pattern, which is determined at the UE based on previous reference signaling previously transmitted to the UE or another UE. At a UE, the sparse reference signaling is received from network equipment, and channel measurement and prediction are performed based on the received sparse reference signaling.

  • Patent number: 10908299
    Abstract: Corrected User Equipment (UE) positioning is based at least in part on signaling that is associated with UE inertial measurements. Such measurements are used in some embodiments to track UE locations along trajectories of UE movement and develop or obtain a model to subsequently predict UE positioning corrections based on channel estimates of a wireless channel. For example, reference signaling may be transmitted by a UE, and the UE then receives positioning corrections or corrected positioning in response to the reference signaling.

  • Patent number: 10897419
    Abstract: A method and apparatus supporting service function chaining in a communication network is provided. Service function chaining requires packets of a service to pass through a defined sequence of service nodes of the network. Traffic engineering support includes defining service segments, determining demands for each service segment, determining flow group conservation constraints using the determined demands, and determining a resource allocation for data links which respects the flow group conservation constraints along with a link capacity constraint. A service-based forwarding operation re-labels packets as they traverse each service segment, and forwards packets toward a destination service node of each service segment.

  • Publication number: 20200374863
    Abstract: Network equipment receives, from User Equipment (UE), information indicative of each of multiple UE locations in a wireless communication network. For each location, a respective antenna beam direction for communications between the network equipment and a UE at each location is determined. A Machine Learning (ML) module is trained using each location as an ML module input and the respective antenna beam direction for each location as an ML module output. The trained ML module is then used to provide beam predictions based on UE location. Based on the current location of a UE, one or more antenna beam directions for communications between the network equipment and the UE at the current location are obtained from the ML module. The UE location is input to the ML module, and the antenna beam direction(s) are then obtained from the ML module output(s).

  • Publication number: 20200112959
    Abstract: Carrier aggregation and dual connectivity leverage multiple component carriers to increase the effective bandwidth available to a given UE. Embodiments of this disclosure extend the concept of carrier aggregation and dual connectivity by using a physical component carrier and one or more virtual component carriers from one physical component carrier group and/or one virtual component carrier group, which have the same carrier frequency and carrier bandwidth as the physical component carrier, to transmit data streams to a user equipment. Data streams communicated over the physical component carrier and the virtual component carrier(s) may be orthogonal in the time domain or code domain. Alternatively, data streams communicated over the physical component carrier and the virtual component carrier(s) may be non-orthogonal, in which case the UE may need to decode the respective data streams using non-orthogonal signal processing techniques.
