  • Patent number: 10326559
    Abstract: A base station may provide both an uplink grant and a downlink grant in a same transmission time interval (TTI), and may provide an indication in the uplink grant that the TTI includes the downlink grant. A user equipment (UE) that receives the uplink grant may provide feedback using identified feedback resources in an uplink shared channel, and other uplink transmissions may be rate matched around the feedback resources in the uplink shared channel. A base station receiving the feedback may monitor the feedback resources to determine whether the downlink grant or one or more of the downlink transmissions were successfully received at the UE. A base station, in some examples, may monitor different sets of resources to determine whether certain of the uplink grant, downlink grant, downlink transmissions associated with the downlink grant, or any combinations thereof, have been successfully received at the UE.

  • Patent number: 10320530
    Abstract: A node (100) of a wireless communication network receives a synchronization signal from a radio device (10). Based on the received synchronization signal, the node determines a time alignment configuration for uplink radio transmissions from the radio device to the wireless communication network. Based on the received synchronization signal, the node further determines Hybrid Automatic Repeat Request feedback information for at least one downlink radio transmission from the wireless communication network to the radio device (10). The node (100) indicates the determined time alignment configuration to the radio device (10). Based on the determined Hybrid Automatic Repeat Request feedback information, the node controls retransmission of the at least one downlink radio transmission.

  • Patent number: 10321497
    Abstract: A method of supporting data transmission of a network node in a wireless communication system includes: receiving downlink data from a Data Network (DN); encapsulating the downlink data with an IP address of an User Equipment (UE) based on whether the DN is an Internet Protocol (IP) based network or a non-IP based network; not encapsulating, if the DN is the IP based network, the received downlink data with the IP address of the UE and encapsulating, if the DN is the non-IP based network, the received downlink data with the IP address of the UE; and transmitting the downlink data encapsulated with the IP address or the downlink data that are not encapsulated with the IP address to an Access Network (AN).

  • Patent number: 10321426
    Abstract: An apparatus and method for detecting synchronization and signals using block data processing in a receiving system are provided. To process an input signal, a cumulative matrix is obtained from an input vector signal for each frame generated from the signal. A primary eigenvector is extracted from the cumulative matrix, and the maximum value of a correlation vector is calculated from the extracted primary eigenvector. A time delay is detected by comparing the calculated maximum value of the correlation vector with a first threshold value, and a delay correlation vector is calculated from the detected time delay. Finally, synchronization and signals are detected by comparing the calculated delay correlation vector with a second threshold value.

  • Patent number: 10313967
    Abstract: A base station utilizes duty cycle requirements of each of multiple base station components to efficiently consume power. The base station may include a synchronization module that allows the base station to send collected data from a cache to a gateway, which then, sends it up to the cloud. The base station may also include a sensor connectivity module that establishes a connection between the base station and data collecting devices deployed to collect data for storage in the cache. A base station controller serves as the cache for the data collected by the sensor module and sends the data to the gateway for synchronization in the cloud using the synchronization module. A base station controller determines/coordinates the duty cycle of the sensor connectivity module and synchronization module in a power efficient way depending on the current power available to the base station, network needs, and the weather conditions.

  • Patent number: 10305659
    Abstract: A method for transmitting a subchannel availability for an uplink (UL) multi-user (MU) transmission is described. An availability of one or more subchannels of an orthogonal frequency division multiplex (OFDM) channel are determined by a first communication device for the UL MU transmission. A High Throughput (HT) Control field of a media access control (MAC) header that includes an indication of the determined availability of the one or more subchannels is generated by the first communication device. A MAC protocol data unit (MPDU) that includes the HT Control field is generated by the first communication device. The MPDU is transmitted by the first communication device to a second communication device via the OFDM channel for a subsequent allocation of radio resources for the UL MU transmission by the second communication device.

  • Patent number: 10305576
    Abstract: Autonomous vehicles such as UAVs or cars provide network access points. User devices connect to the network access points and network access is monitored. User location data is also monitored. A profile of the user is generated from the gathered data. Advertisements are selected based on a profile of the user and the current location of the user. The autonomous vehicles may be distributed geographically to provide a network access to a geographic area. In response to detecting that a user device is moving out of a coverage area of an autonomous vehicle, nearby autonomous vehicles are identified. If the user device is in the coverage area of a nearby autonomous vehicle, the network connection to the user device is transferred to that vehicle.

  • Patent number: 10278088
    Abstract: Aspects of the present disclosure provide for enhanced channel estimation in a wireless communication network. Uplink channel estimation may be enhanced by increasing the uplink transmit power of an uplink reference signal. For example, the uplink transmit power may be increased by multiplying a measured downlink path loss by a predetermined factor to produce an increased downlink path loss and calculating the uplink transmit power based on the increased downlink path loss. Downlink channel estimation may be enhanced by increasing a number of tones on a downlink reference signal assigned to a scheduled entity relative to the number of tones assigned to other scheduled entities.

  • Patent number: 10257848
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may communicate with multiple user equipments (UEs) in a wireless system supporting directional transmission in shared spectrum (e.g., in millimeter wave (mmW) spectrum). The base station may contend for the channel (e.g., using a listen-before-talk (LBT) procedure) and, upon success, transmit a directional channel reservation (CR) signal to each of the multiple UEs. The CR signal may reserve the channel for a specific time period and indicate a start time, an end time, or both. The UE may respond with another CR transmission. In some examples, the base station may transmit CR signals to each of the UEs in a single burst transmission. In other examples, the base station may transmit CR signals to the UEs sequentially, so that if a UE does not respond, the reserved time may be allotted to another UE.

  • Patent number: 10243809
    Abstract: Some embodiments provide a method for troubleshooting a virtual network that is implemented over multiple computing devices, which include first and second host machines that host virtual machines (VMs). Each VM interfaces the virtual network through a set of virtual network interface controllers (VNICs). The method provides a command line interface (CLI) for debugging and monitoring the virtual network. In response to receiving a first command at the CLI that identifies a first VNIC, the method retrieves from the first host machine a first set of network service status data associated with the first VNIC. In response to receiving a second command at the CLI that identifies a second VNIC, the method retrieves from the second host machine a second set of network service status data associated with a second VNIC. The method presents the retrieved first and second sets of network service status data through the CLI.
