  • Patent number: 11991649
    Abstract: A communication system includes a first wireless base station supporting communications with multiple mobile communication devices. The first wireless base station is limited to an amount of power it is able to consume. For example, the wireless base station receives power consumption information from a power consumption manager. To control power consumption with respect to the received power consumption information, the wireless base station determines (such as based on an estimation, calculation, measurement, etc.), an amount of a power consumption by the wireless base station while communicating with multiple mobile communication devices. The wireless base station adjusts wireless communications transmitted from the wireless base station to maintain the power consumption of the wireless base station with respect to a power consumption limit as indicated by the received power consumption information.

  • Patent number: 11979924
    Abstract: Various embodiments comprise systems, methods, and apparatus enabling communications between a mobile network node (e.g., base station, eNB, gNB) and a large number of Internet of Things (IoT) devices by defining IoT device groups comprising at least one primary IoT device and a plurality of secondary IoT devices. The mobile network node communicates directly with group primary IoT devices via a mobile network protocol, and the group primary IoT devices further communicate with the secondary IoT devices via a local wireless protocol. Identifiers are used to identify secondary IoT devices that are the source of transmitted uplink messages, or the target/destination of downlink messages. Identifiers may be bundled or concatenated such that the primary IoT devices can manage messages or other communications to/from the base station, which in turn handles all backhaul services necessary to support the group of IoT devices.

  • Patent number: 11974315
    Abstract: Methods and apparatus for managing spectrum in a CBRS network to provide services to user equipment devices located at a customer's premises. In various embodiments, the customer premises has no landline connection. An exemplary method embodiment includes the steps of: receiving, by the CBRS CPE base station, over the air from each of a plurality of Citizens Broadband Radio Service Fixed Wireless Access (CBRS FWA) tower base stations a reference signal; selecting, based on the strength of each of the received reference signals, a primary CBRS FWA tower base station from the plurality of CBRS FWA tower base stations; establishing, by the CBRS CPE base station, a wireless communications link connection with the CBRS FWA tower base station selected as the primary CBRS FWA tower base station; reserving, by the CBRS CPE base station, an amount of spectrum for communicating with one or more auxiliary CBRS FWA tower base stations.

  • Patent number: 11968654
    Abstract: In a (5G CBRS) network having a (CBSD) base station communicating with a (SAS) bandwidth manager via a cable modem (CM), the CM maintains a long timer and a short timer for each bandwidth allocation to the CBSD. When the CM receives a heartbeat message from the CBSD, the CM re-starts the long and short timers and transmits the heartbeat message to the SAS. When the short timer expires, the CM re-starts the short timer and transmits a copy of the stored heartbeat message to the SAS. When the long timer expires, the CM stops transmitting a copy of the stored heartbeat message to the SAS. In this way, the CM effectively extends the time limit before the SAS will de-allocate bandwidth from the CBSD to handle situations where the CBSD is temporarily unable to send heartbeat messages to the SAS even though the CBSD still needs the allocated bandwidth.

  • Patent number: 11956641
    Abstract: In a wireless communications system, such as a 5G CBRS system, a Spectrum Access System (SAS) assigns portions of the (CBRS) spectrum to associated base stations (CBSDs). In some embodiments, a central spectrum-database server receives information about spectrum allocations made by two or more different SASs operated by different companies and tabulates that information in a combined spectrum database that each SAS can independently retrieve for use in allocating bandwidth to its CBSDs. In some implementations, the messages between each SAS and multiple associated CBSDs are transmitted via a domain proxy that snoops on multiple spectrum-allocation-related messages (e.g., spectrum grant/revocation messages and/or heartbeat messages) to gather the information to be transmitted to the server, where the information does not include any company- or network-sensitive information.

    Abstract: Methods and apparatus for enhancing performance of a wireline communication network backhaul for wireless nodes based on data traffic and node characterization. In one embodiment, the node comprises a small-cell or other wireless base station (e.g., one utilizing unlicensed or quasi-licensed spectrum such as CBRS or C-Band) that is backhauled by a DOCSIS system within a managed HFC network, and the methods and apparatus utilize such factors as traffic load, geographic or topological location, node technology type, and user device profile for each node to determine scheduling of traffic over the wireline transmission medium used for the delivery of services. In another embodiment, the foregoing factors can be weighted for further determination related to an assignment of the time slots or other resources for the delivery of services.

  • Publication number: 20240048997
    Abstract: Apparatus and methods for providing multi-tier quasi-licensed spectrum wireless service via a common wireless access node such as a small-cell. In one embodiment, the quasi-licensed system utilizes multi-sector antennae to create antenna lobes adaptively according to parameters associated with different cell sectors, such as user traffic, random access requests, and/or interference. In one variant, when the user traffic or interference is determined to be very high in a particular sector, the sector is configured and activated based on the availability of low-noise spectrum. In another variant, when a new sector is created, the electrical power resources available for that sector are checked, and based on the amount of power available at that sector, either CBSD Category A or B status is allocated to that sector.
