Soft Handoff Patents (Class 455/442)
  • Patent number: 11006337
    Abstract: According to one configuration, a system includes user equipment in communication with a wireless base station. The user equipment receives a notification from a first wireless access point of multiple wireless access points. The notification indicates a set of candidate wireless access points in the wireless network environment in which to selectively perform a handoff from a first wireless access point. The user equipment monitors for occurrence of a trigger condition. In response to detecting a trigger condition, the user equipment identifies (such as selects) a second wireless access point (from the set of candidate wireless access points) in which to perform the handoff. Via communications from the user equipment to the second wireless access point, the user equipment initiates the handoff. The user equipment notifies the first wireless access point of the attempted and/or failed attempt of the handoff to the second wireless access point.

    Abstract: Systems and methods are described for determining an access node for a wireless device. A first signal may be transmitted from a first access node with an increased signal level. An indication of a first adjustment factor based on the increased first signal level may also be transmitted from the first access node. Signal information may then be received from a wireless device, where the signal information includes a determined first signal level associated with the first access node and a determined second signal level associated with a second access node. The determined first signal level from the signal information may comprise a received signal level of the first signal decreased by the first adjustment factor. Based on the signal information, one of the first access node and the second access node may be selected for communication with the wireless device and the wireless device may be instructed to communicate with the selected access node.

  • Patent number: 10455386
    Abstract: The invention relates to methods for controlling transmission of machine type communication data to or from machine type communication devices within a mobile communication system. Furthermore, the invention relates to a mobile terminal and network node for implementing such methods, and to implementations of the methods in software. In one aspect of the invention, a mechanism to perform transmission planning (or scheduling) of data transmission from machine type communication devices is suggested. This transmission planning may be based on load estimates at different points in time (e.g. for individual timeslots), and may allow the scheduling of transmissions of machine type communication data at points in time, where the load in the mobile/wireless communication network is expected to be low.

  • Patent number: 10448400
    Abstract: The present disclosure relates to a technique for radio link monitoring in a wireless communication system, and to operation procedures of the base station and user equipment and a method for radio link quality evaluation on the basis of the technique. In the method, the user equipment divides the downlink channel bandwidth into multiple frequency ranges, measures channel states for each frequency range, and evaluates the radio link quality based on channel state measurement results. Thereafter, the user equipment sends frequency range quality information to the base station, which may then utilize the same for downlink resource allocation. Hence, it is possible to solve the problem of the existing scheme wherein the user equipment enters the physical layer problem detection state or the radio link failure state although a frequency range usable for service provisioning is present within the downlink channel bandwidth.

  • Patent number: 10299169
    Abstract: Aspects describe renegotiation of quality of service parameters to resolve maximum bit rate mismatches and/or other quality of service parameter mismatching issues that might arise during an inter-radio access technology handover. At about the same time as a mobile device moves from a source network to a target network, the target network dynamically initiates a quality of service modification procedure. The quality of service modification procedure can help resolve the maximum bit rate mismatches and/or the other quality of service parameter mismatching issues.

  • Patent number: 10292063
    Abstract: The present application provides a method for enhancing reliability of wireless communication, comprising: monitoring, by a user equipment (UE), quality of downlink transmission between the UE and a base station (BS); and measuring, by the UE in response to a trigger event, transmission quality of at least one beam used for the downlink transmission between the UE and the BS, wherein the trigger event is used to indicate that quality of the downlink transmission between the UE and the BS does not meet a first preset condition. The present application further discloses another method for enhancing reliability of wireless communication and a related device and system. By means of the solutions disclosed in the present application, transmission quality of a beam used for uplink/downlink transmission between a BS and a UE can be non-periodically measured based on event trigger, which improves real-time performance of detection and greatly enhances reliability of wireless communication.

  • Patent number: 10271285
    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.
