  • Patent number: 11672031
    Abstract: A first control node may communicate with a user equipment (UE) using an integrated access and backhaul (IAB) network, and a second control node may manage a configuration of the IAB network. The second control node may not have the information needed to configure the IAB network, such as quality of service (QoS) information associated with a data radio bearer (DRB) used for communications between the first control node and the UE, and thus may not be able to configure a user plane interface tunnel and/or a radio link control (RLC) channel to assist with satisfying the QoS level. Some techniques and apparatuses described herein enable the second control node to receive QoS information associated with setting up a user plane interface tunnel between the first control node and an IAB node that serves a UE for which the user plane interface tunnel is being set up.

  • Patent number: 11663073
    Abstract: An apparatus and method for efficiently transmitting data are described. A transmitter sends data to a receiver. An encoder of the transmitter divides a received first block of data into multiple sub-blocks. The encoder selects a portion of each sub-block to compare to one another. A portion in a particular sub-block has a same offset and a same size as other portions of other sub-blocks. If the encoder determines the multiple portions match one another, the encoder sends, to the receiver, a second block of data corresponding to the first block of data. The second block of data has a same size as a size of the received first block of data, and the second block of data includes security data from one of multiple error correction schemes. Therefore, the second block of data provides security without increasing an amount of data to transmit.

    Abstract: A wireless communication apparatus includes a transmission/reception unit, a measurement unit, a physical layer, an acquisition unit, and a control unit. The transmission/reception unit transmits/receives packets to/from a communication peer. The measurement unit starts measuring a time period after a predetermined time from an end of the packet transmitted to the communication peer. The physical layer detects a synchronization code included in the packet transmitted from the communication peer and generates a synchronization detection signal. The acquisition unit acquires a measured value by the measurement unit when receiving the synchronization detection signal. The control unit has a function to change the physical layer to a physical layer with a different error tolerance, and calculates a propagation delay by subtracting a length of a synchronization code from the measured value and judges whether to update the physical layer or not depending on the propagation delay.

  • Patent number: 11290163
    Abstract: Aspects of the disclosure relate to a selection scheme implemented by a scheduler in a multiple-input multiple-output (MIMO) network to identify which users to schedule simultaneously during the same time slot. For downlink communications and a particular frequency wholeband or sub-band, the scheduler can determine downlink channel information using uplink channel information for channels between base stations and UEs. The scheduler can then determine a strength of the channels using the downlink channel information, order the UEs using a fairness metric based on the channel strengths, and compute one or more QR decompositions to identify whether a spatial dimension of a UE is roughly or approximately orthogonal to spatial dimension(s) of other UEs selected to be served during a time slot being scheduled. If the spatial dimensions are roughly or approximately orthogonal, the scheduler selects the UE to be served at the same time as other UEs already selected.

  • Patent number: 11283589
    Abstract: Systems, apparatuses, and methods for implementing a deskewing method for a physical layer interface on a multi-chip module are disclosed. A circuit connected to a plurality of communication lanes trains each lane to synchronize a local clock of the lane with a corresponding global clock at a beginning of a timing window. Next, the circuit symbol rotates each lane by a single step responsive to determining that all of the plurality of lanes have an incorrect symbol alignment. Responsive to determining that some but not all of the plurality of lanes have a correct symbol alignment, the circuit symbol rotates lanes which have an incorrect symbol alignment by a single step. When the end of the timing window has been reached, the circuit symbol rotates lanes which have a correct symbol alignment and adjusts a phase of a corresponding global clock to compensate for missed symbol rotations.

  • Patent number: 11252686
    Abstract: The present disclosure relates to transmitting synchronization signals and in particular to so called beam sweep. In particular the disclosure relates to methods for providing synchronization using synchronization sequences that are transmitted at different points in time. The disclosure also relates to corresponding devices and computer programs. A method in a network node, for transmitting synchronization sequences of a synchronization signal to one or more receiving wireless devices, comprises determining multiple synchronization sequences, such that each synchronization sequence comprises a respective timing indication, whereby each synchronization sequence enables determination of a time of an event in a receiving wireless device and transmitting the synchronization sequences to the one or more wireless devices, at different points in time.

  • Patent number: 11246059
    Abstract: A method performed by a transmitting device is disclosed herein. The transmitting device operates in a communications network. The transmitting device performs a reset on a buffer of the transmitting device. The transmitting device then switches, based on the performed reset, a first value in an indication to a second value. The indication is of the reset of the buffer. The transmitting device sets the indication to the second value for all packets generated by the transmitting device after the performed reset. This is set until the second value is switched again by the transmitting device in another indication, based on another performed reset of the buffer. The transmitting device then sends the indication with the second value to a receiving device operating in the communications network. The second value indicates that the reset was performed by the transmitting device.

  • Patent number: 11224013
    Abstract: In multicarrier networks mobile devices can be distributed amongst carriers based on different criteria. However, prioritization may cause certain devices to end up on a carrier that is not optimal for the network. When there is a deployment of different types of cells (e.g., macro cells, small cells, etc.), the cells can use the same frequency. Consequently, a priority value contained within a system information broadcast message can override the mobile default cell transition procedures and thus select a neighboring cell based on additional criteria. Thus, small cells can be deployed to offload traffic from macro cells in spite of the small cells and macro cells operating in the same frequency band.

  • Patent number: 11219026
    Abstract: Methods and apparatus for providing quasi-licensed spectrum access within an area or application so as to enable “end to end” IoT (Internet of Things) device connectivity. In one embodiment, the quasi-licensed spectrum utilizes 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum allocated by a Federal or commercial SAS (Spectrum Access System) to a managed content delivery network that includes one or more wireless access nodes (e.g., CBSDs (Citizens Broadband radio Service Devices) and IoT hubs or gateways) in data communication with a controller. In one variant, the controller dynamically allocates (i) spectrum within the area or venue within CBRS bands, and (ii) MSO (multiple systems operator) users or subscribers to CBRS bands or IoT (Internet of Things) bands (e.g., public ISM (industrial, scientific and medical)) bands to maximize connectivity and performance.

  • Patent number: 11197163
    Abstract: All or a portion of a timeslot of a slotted communication system may be dynamically designated for transmitting or for receiving. For example, a timeslot originally designated for receiving information at a wireless node may be temporarily designated for transmitting information from the wireless node. Such a designation may be made to accommodate a temporary asymmetry in traffic flow between wireless nodes or may be made based on other criteria. In some aspects, a resource utilization messaging scheme may be employed to mitigate interference associated with the designation of timeslots for transmitting or receiving.
