Dynamic Allocation Patents (Class 455/452.1)
  • Patent number: 10299203
    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.

  • Patent number: 10270547
    Abstract: A system and method for detection of complex sinusoidal signals. The method can include obtaining a set of complex-valued samples of one or more signals, in the presence of unknown noise, using a plurality of sensors. The presence of ? candidate complex sinusoids can be assumed. Then, ? candidate complex sinusoids in the set of complex-valued samples can be estimated. The method can include comparing a measurement of the energy of the ? estimated candidate complex sinusoids with a threshold value. Based on the comparison, a determination can be made whether to assume a different number of candidate complex sinusoids and repeat the estimation and the comparison steps, or to specify the estimated ? candidate complex sinusoids as detected complex sinusoids. The threshold value can be determined using a penalty value which reduces the probability of overestimating the number of complex sinusoids.

  • Patent number: 10129905
    Abstract: A communication device (10) receives an uplink grant from a node (100) of a cellular network. The uplink grant indicates uplink radio resources allocated to the communication device (10) in reoccurring time intervals. For each of these time intervals, the communication device (10) selects between an active mode and an inactive mode. In the active mode the communication device (10) performs an uplink transmission in the allocated uplink radio resources. In the inactive mode the communication device (10) performs no uplink transmission in the allocated uplink radio resources.

  • Patent number: 10129719
    Abstract: Application states of applications associated with a communication device can be network controlled. An application agent, associated with an application used by the communication device, controls transitioning the application between application states based on network indicators received or network events detected from a communication network. The application states include active state or doze state. An application management component associated with the communication network at least partially controls transitioning the application between application states to facilitate controlling network traffic or reducing network congestion. The application agent or application management component can map application states to various factors, including radio states, congestion level, application performance indicators, network policies, or user policies, to facilitate determining which application state to apply to an application at a given time.

  • Patent number: 10117241
    Abstract: Disclosed is a method and system for adjusting a transport block size used for uplink transmissions from a user equipment device (UE) when engaging in uplink coordinated multipoint service (UL CoMP), under conditions in which a propagation delay to a receiving CoMP base station (BS) exceeds a threshold. Based on predicted delay reported to a serving BS from the CoMP BS, the serving BS may compute a reduced transport block size such that uplink resource blocks transmitted from the UE to the CoMP base station will be temporally under-filled by an amount corresponding to the predicted delay. As received at the CoMP BS, the under-filled resource blocks will not overrun their assigned transmission time interval (TTI), and therefore will not be a source of potential interference.

  • Patent number: 10111106
    Abstract: A network infrastructure equipment establishes a configuration of radio resources within a second frequency band for use by a terminal device for communications with network infrastructure equipment based on a first radio access technology and communicates an indication of that to the terminal device. The terminal device establishes a configuration of radio resources for use by the terminal device for communications based on a second radio access technology and determines if there is any overlap in radio resources configured for use by two different radio access technologies, and if so communicates an indication of that to the network infrastructure equipment. In response the network infrastructure equipment establishes a replacement configuration of radio resources for communications with the terminal device based on the first radio access technology that avoids the radio resources indicated as subject to overlap, and transmits an indication of the replacement configuration to the terminal device.
