  • Patent number: 9832715
    Abstract: A radio network node (12) communicates with user equipments, UEs, (10) over a radio interface and estimates one or more quality factors, associated with each of a first and second network, that depend on a load or an expected UE behavior or an uplink channel quality for one or both of first and second networks. The node (12) determines one or more network selection parameters based on the estimated one or more quality factors, and communicates the one or more network selection parameters to at least one UE (10) for enabling the UE to select one of the first and second networks for subsequent access by the at least one UE. The UE receives from the radio network node one or more network selection parameters. The UE uses the one or more network selection parameters to select one of first and second radio networks and then accesses the selected radio network.

  • Publication number: 20170311255
    Abstract: According to an aspect of the teachings herein, dynamic cell activation uses the spectrum of a spectrum owner to provide wireless communication services in a location that may not be served by the spectrum owner. For example, a base station determines which one of two or more network operators is targeted by a wireless device requesting access, and correspondingly activates communication services for the device, using spectrum owned by the targeted network operator. Advantageously, the cell(s) may not be persistent and instead may be provided only when access is requested and then only in the spectrum of the targeted network operator(s). This approach offers power savings as compared to providing persistent cells for multiple network operators. Further, the contemplated arrangement makes it economic for third parties and network operators to use of operator-owned spectrum that might otherwise remain unexploited in the involved locations.

  • Publication number: 20170289891
    Abstract: An arrangement for controlling energy consumption of a network node associated with a cell includes a terminal activity monitor configured to detect active terminals served by the cell. A transmission controller is connected to the terminal activity monitor and is configured to restrict transmission downlink in the cell during time periods when there are no active terminals served by the cell. During these time periods transmission is restricted to intermittent transmission of information assisting active terminals not served by the cell in finding the cell.

  • Publication number: 20170264414
    Abstract: A receiver apparatus receives a terminal-specific demodulation reference signal having a rank k and estimates an effective multi-layer channel response, using the received terminal-specific demodulation reference signal. The receiver demodulates first data symbols from first time-frequency resource elements, using the estimate of the effective multi-layer channel response and using a first symbols-to-virtual-antenna mapping matrix M to obtain nc modulation symbols from each of the first time-frequency resource elements, wherein nc>1 and wherein the first symbol-to-transmit-layer mapping matrix M has dimensions k by nc. The first data symbols are decoded to obtain downlink control information assigning second time-frequency resource elements to the receiver.
