Multiple Base Stations Patents (Class 455/524)
  • Patent number: 11963121
    Abstract: A communication technique for synchronizing a set of radio nodes is described. In this communication technique, the radio node arbitrates (e.g., using a precision time protocol or PTP) with the other radio nodes based on a selection technique to select a synchronization master in the set of radio nodes. This synchronization master may be selected to have a predefined performance based on a type of communication environment of the set of radio nodes. For example, the type of communication environment may include overlap between at least one of the radio nodes in the set of radio nodes and a macrocell in a cellular-telephone network, or may exclude overlap between the set of radio nodes and the macrocell. Moreover, the synchronization master may specify time, frequency, and phase synchronization for the set of radio nodes. Thus, when the synchronization master is different from the radio node, the radio node synchronizes with the synchronization master.

  • Patent number: 11889451
    Abstract: In various embodiments, crowd sourcing techniques are provided to enable RTT-based positioning of UE. To address issues of discovering which beacons (e.g., Wi-Fi APs, cellular base stations, BLE transmitters, etc.) support measurement of RTT (e.g., according to IEEE 802.11mc, 3GPP Release 16, etc.), beacon RTT capabilities may be crowd-sourced from UE and maintained by a cloud-based location platform in a beacon database (or more specifically, a RTT database portion thereof). To address the issue of determining physical antenna positions, RTT measurements may be crowd-sourced from UE for those beacons that are RTT capable, and used by a trilateration algorithm (e.g., a WLS multilateration algorithm) to determine physical antenna positions, which also may be maintained in the beacon database. Accuracy of the trilateration may be enhanced by obtaining raw GNSS measurements (e.g., pseudoranges) from the UE, and performing a cloud-based RTK GNSS position fix for the UE.

  • Patent number: 11849195
    Abstract: Methods and apparatuses for improving satellite broadcasting services by enhancing set-top box (STB) signal reception during weather conditions that obstruct the transmission of RF signals from one or more satellites to a receiving antenna (e.g., a dish antenna) are described. To prevent loss of satellite broadcasting services, an enhanced STB signal system may be arranged between the receiving antenna and an STB in order to provide an enhanced signal to the STB in the event that the RF signals received by the receiving antenna are not able to be decoded. The enhanced STB signal system may transmit an enhanced signal to the STB instead of a signal that was only derived from the receiving antenna. The enhanced signal may comprise a combination of signals that derive from other receiving antennas different from the receiving antenna, as well as the signal derived from the receiving antenna.

  • Patent number: 11800471
    Abstract: The present invention relates to selection of synchronization source among various synchronization sources which include sources determining the synchronization signal from the network such as base stations (network nodes) or user equipments which receive the synchronization signal possibly over other hops from the base station, and which further includes sources which do not determine their synchronization signal from the network. The selection of the synchronization source is performed by choosing the source with the most reliable synchronization signal based on a metric calculated for each of the sources considered. In particular, the metric is based on the type of the source, number of hops between the network and the source and/or received signal quality. After selecting the source, the timing of the device is adapted accordingly.

  • Patent number: 11483102
    Abstract: A review and retry mechanism ensures a port channel can be configured to provide and maintain a minimum data speed. A timer-based review sequence reviews the constituent interfaces of a port channel to determine if a minimum speed requirement is met. If the minimum speed cannot be fulfilled, the port-channel member interfaces are un-programmed and removed from the port-channel, rendering the port-channel functionally inactive, thereby preventing network traffic loss. A timer-based retry sequence attempts to program the constituent interfaces. The minimum speed requirement of the interfaces is checked in the next review cycle. If the minimum speed requirement is met, then the review and retry mechanism halts and the port channel continues to remain active; otherwise, the interfaces are un-programmed and the process repeats.

  • Patent number: 11012892
    Abstract: A resource obtaining method, apparatus, and system, wherein the method includes: when a first edge node receives a first resource obtaining request sent by a second edge node, and a first target resource is not locally cached, the first edge node may determine, using shared popularity information of the first target resource, whether the first target resource needs to be cached. The shared popularity information of the first target resource is determined by a quantity of obtaining requests for the first target resource that are received by the first edge node from the first edge node and another edge node. Therefore, it is determined, using the shared popularity information, whether the first target resource needs to be cached.

  • Patent number: 10952157
    Abstract: A system and method are provided to efficiently provide coverage within a large scale of a building by identifying user equipment (UE) on a floor by floor basis using a distributed antenna system (DAS) and pseudo timing advance values (TA) assigned to each floor. By applying different pseudo delays on a plurality of distributed antenna basis located at each floor, a base station can know a floor at which a user equipment is located through a timing advance value of the user equipment. When a traffic amount increases based on the measured traffic amount of each floor, the base station may increase a carrier and adjust an amplifier output on a floor by floor basis, thereby efficiently using power and maintaining a user's quality of experience (QoE).

  • Patent number: 10602527
    Abstract: Techniques for channel selection and related operations in a shared spectrum environment are disclosed. In one example, a channel selector or the like may be used to select one of a number of available channels as an operating channel based on a comparison of cost functions for each of the available channels, with the cost functions being based on separate utility and penalty metrics. In another example, a channel scanner or the like may be used to trigger a channel scan in response to a channel quality metric indicating poor service for a threshold number or proportion of access terminals. In another example, an operating mode controller may be used to trigger a Time Division Multiplexing (TDM) mode on an operating channel in response to a utilization metric being above a threshold. The TDM mode may cycle operation between activated and deactivated periods in accordance with a TDM communication pattern.
