    Abstract: User equipment (UE) can select a connection type for a retry of a failed call based on system information blocks (SIBs) received from a serving base station of a first radio access layer of a telecommunication network. When the UE experiences a call setup failure of a call attempted through the serving base station of the first radio access layer, the UE can determine whether neighbor information within the SIBs includes information about a neighboring base station of a second radio access layer. If it does, the UE can select a retry connection type as a connection to the neighboring base station of the second radio access layer. If it does not, the UE can select the retry connection type as a connection to an alternate network. The UE can then retry the call through the selected retry connection type.

  • Patent number: 11206682
    Abstract: Group transmission of data from a group of User Equipment devices to a network node of a cellular communication system where communication between devices is effected by device-to-device technology can provide significant improvements in uplink coverage and user bit rate. However, the benefits of group transmission means that not all devices of a group have sufficient network coverage to reliably receive a grant signal scheduling uplink resources from a network node. Methods, devices and a network node are proposed that enable the dynamic selection of either a direct grant mode, in which each device receives the uplink grant directly from the network, or a relayed grant mode, in which a device acting as group coordinator relays the grant to all members of the group, to ensure optimal performance for group transmissions. The selection is dependent on at least one determined condition relating to the group of devices and/or the group transmission.

    Abstract: A user equipment (UE) may transmit a UE-generated uplink message to a base station to request resources for an uplink transmission. The UE may be configured to send the message (e.g., a scheduling request (SR)) using different transmission modes. For example, the UE may transmit the SR using a scheduled mode where the UE conveys the SR along with another uplink message (e.g., a control message). In some examples, the UE may transmit the SR using an autonomous mode where the UE transmits the SR in resources reserved for SR transmissions. The UE may determine which transmission mode to use based on certain characteristics of the SR or the data associated with the SR.

  • Patent number: 10945162
    Abstract: A user equipment (UE) device is scheduled to transmit an uplink data transmission to its serving base station. The uplink data transmission includes a special subframe that has a different subframe structure than a subframe structure used by at least one other UE device being served by the serving base station. For example, the special subframe includes a blanked portion of the first symbol of the special subframe and a higher Reference Signal symbol density when compared to the subframe structure used by other UE devices. A target base station receives and decodes the uplink data transmission, utilizing the features of the special subframe to acquire and estimate the uplink channel between the UE device and the target base station. After decoding the uplink data transmission, the UE device is handed over from the serving base station to the target base station.

  • Patent number: 10887187
    Abstract: Techniques for integrating a device platform in a core network or MEC environment, and managing data communications associated with devices are presented. The device platform, integrated with the core network or MEC environment, can comprise a communication management component (CMC) that can manage communication of data associated with devices connected to the core network. CMC can receive data and metadata from a device, analyze the data and metadata, and, based on the analyzing and data management criteria, determine whether any, all, or a portion of the data is to be communicated to a second device associated with the core network or associated communication network. CMC can be trained, using machine learning, to learn to identify device types, communication protocols, and data payload formats of devices. Based on the analyzing and the training, CMC can determine the device type, communication protocol, and data payload format associated with the device.

  • Patent number: 10735949
    Abstract: A system for updating a preferred nodes list for a wireless device in a wireless network includes a server in communication with a plurality of nodes each configured to deploy a radio air interface to provide wireless services to wireless devices. The server includes a processor configured to instruct, in response to a trigger, a first node to send a message to a wireless device connected to the first node. The message instructs the wireless device to contact the server for an updated preferred nodes list. The processor receives a request for the updated preferred nodes list from the wireless device, and provides the updated preferred nodes list to the wireless device. The updated preferred nodes list enables the wireless device to change from connecting to the first node included in the preferred nodes list to connecting to a second node included in the updated preferred nodes list.

  • Patent number: 10694469
    Abstract: A wireless telecommunication system includes base stations for communicating with terminal devices. One or more base stations support a power boost operating mode in which a base station's available transmission power is concentrated in a subset of its available transmission resources to provide enhanced transmission powers as compared to transmission powers on these transmission resources when the base station is not operating in the power boost mode. A base station establishes an extent to which one or more base stations in the wireless telecommunications system supporting the power boost operating mode conveys an indication of this to a terminal device. The terminal device receives the indication and uses the corresponding information to control its acquisition of a base station of the wireless telecommunication system, for example by taking account of which base stations support power boosting and/or when power boosting is supported during a cell attach procedure.

  • Patent number: 10694474
    Abstract: Method performed by a network node for reducing interference in neighboring cells. The network node operates in a communication network, which is adapted to wirelessly serve a UE via a serving Radio Access, RA, node. The network node obtains a determination of at least one of Reference Signal Received Power, RSRP, and Reference Signal Received Quality, RSRQ, from the serving RA node as received by the UE and a determination of at least one of RSRP and RSRQ from a neighboring RA node as received by the UE, when the UE is connected to the serving RA node. The network node further decides to reduce a transmit power of the serving RA node serving the connected UE, when the determined RSRP and/or RSRQ of the serving RA node is higher than the RSRP and/or RSRQ of the neighboring RA node, in order to reduce the interference in neighboring cells caused by the serving RA node.

  • Patent number: 10681564
    Abstract: The present disclosure relates to data transmission between a node and peer nodes. Interference alignment techniques are used to mitigate interference between the nodes on a line of sight channel A data stream is exchanged in two transmissions between the node and a peer node. The two transmissions are formed according to an interference alignment precoding matrix. The node may include linearly aligned antennas. To mitigate further the interference between the node and the peer node, a pair of these antennas is selected for communication with the peer node as a function of a distance between the node and the peer node and as a function of a wavelength of the communication. Channel state information may be exchanged between the node and the peer node for precoding matrix selection and for antenna selection. The antennas used for communication between the nodes and the peer nodes may be beamforming antennas.
