  • Publication number: 20210377327
    Abstract: An end user premises device is provided that includes a memory, one or more transceivers, and one or more processors. The one or more transceivers are configured to communicate with one or more stations in a network and a client device. The one or more processors are configured to receive a first user request for data from the client device using the one or more transceivers, determine a first point in time for retrieving the data based on an amount of charge in batteries of the one or more stations in the network, retrieve, at the first point in time, the data from a remote server via the network using the one or more transceivers, store the data in the memory, and in response to a second user request, transmit the data to the client device using the one or more transceivers.

  • Publication number: 20210313669
    Abstract: A method and an antenna system are provided for a high-altitude platform (HAP) configured to move in a pattern in the stratosphere to provide coverage to a region of interest and compensate for HAP movement relative to the region of interest. HAP movement is monitored. When it is determined that the HAP has moved relative to the region of interest and, based on the relative movement, a first one of a plurality of antennas in the HAP is no longer able to cover a selected portion of the region of interest, an antenna array switching circuit in the HAP is used to adjust beams transmitted by the antennas by switching to a second one of the plurality of antennas to cover the selected portion of the region of interest, such that the communication services provided to the region of interest are not interrupted due to the movement of the HAP.

  • Publication number: 20210313707
    Abstract: This document describes techniques and apparatuses that include a three-dimensional (3D) antenna module for transmitting or receiving electromagnetic millimeter waves (mmWaves). In general, a user equipment (UE) may include the 3D antenna module in a corner of a housing of the UE. The 3D antenna module may include three antenna panels that are generally planar and generally orthogonal to three respective axes of a Cartesian-coordinate system. The 3D antenna module may transmit and receive the electromagnetic mmWaves as part of a wireless link between the UE and another device, such as a satellite that is part of a wireless-communication network. In general, the 3D antenna module may mitigate propagation losses and allow the UE to maintain a link-budget for the wireless link.

  • Publication number: 20210313681
    Abstract: A method and apparatus are provided for nulling a radio frequency (RF) beam for a high-altitude platform (HAP). A transmitter generates an RF signal. A primary antenna system generates an RF beam based on the RF signal. One or more processors determine a result indicating whether to modify the RF beam. When the result indicates to modify the RF beam, a detachable nulling subassembly generates nulling signals based on the RF signal to modify the RF beam generated by the primary antenna system.

  • Publication number: 20210314793
    Abstract: A high-altitude platform (HAP) node provides communication service during an emergency. The HAP node uses a first network to provide communication services for handling calls initiated by at least one user equipment (UE). The HAP node detects that an emergency disruption has occurred that prevents the use of the first network. In response to detecting the occurrence of the emergency disruption, a mobile terminal (MT) in the HAP node searches for a second network able to accept emergency calls. The HAP node determines whether the second network will handle all calls initiated by the at least one UE or only emergency calls generated by the at least one UE. The HAP node handles the calls based on the determining and through the use of the second network.

  • Publication number: 20210274463
    Abstract: Determining a location of a user equipment includes transmitting, by one or more processors from a network node, a first beam having a first frequency range in a first area and a second beam having a second frequency range in a second area. The first area is larger than and encompasses the second area. A request for determining the location of the user equipment is received. The one or more processors may then cause the second beam to sweep within the first area, receive a second signal from the user equipment indicating when the second beam is swept over the location of the user equipment and data related to signal measurements of the second beam at the user equipment, and determine the location of the user equipment based on a pointing direction of the second beam relative to a position of the node of the network and the received data.

  • Publication number: 20210127280
    Abstract: The disclosure provides a method of operating a communication network. The method includes receiving input data related to a state of the communication network and operation of the communication network. The method then includes determining a policy for the communication network based on the input data. The policy is a set of features for forming a plurality of communication links in the communication network over a time interval. The plurality of communication links provides one or more paths through the communication network. Determining the policy is based at least in part on utility values of previous policies. The utility values of previous policies are derived using simulation and/or real-world implementation of the previous policies. The communication network is then operated to implement the policy in the time interval.

  • Publication number: 20210084649
    Abstract: Assigning resources for transmitting signals to a user equipment includes receiving, at a first node having a first coverage area, an indication of an overlapping coverage area from a second node when the second node is a non-terrestrial node having a second coverage area that overlaps with the first coverage area. Request for resources are received from a user equipment in the first coverage area, and resources assignments to the user equipment are determined based on the first message and the received request. The resource assignments include a first resource assignment for communication with the first node and a second resource assignment for communication with the second node. The resource assignments are transmitted in a second message to the user equipment, which then communicates with the first node using the first resource assignment and to communication with the second node using the second resource assignment.
