  • 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: 10368246
    Abstract: In the static and exclusive spectrum allocation paradigm, the spectrum-access parameters for a service are chosen to mitigate potential harmful-interference and ensure minimum performance under worst-case conditions. The new dynamic spectrum-sharing paradigm necessitates dynamically defining and enforcing the spectrum-access rights while accommodating the dynamics of the RF environment and the spectrum-access scenarios. To enforce spectrum-access rights, emphasis is placed on capturing the use of spectrum by an individual transceiver. Spectrum-access rights are articulated in terms of the characterization of the spectrum used by an individual transceiver in the space, time, and frequency dimensions. In order to estimate the use of spectrum in real time, an RF-sensor network is employed, the network uses interference-tolerant algorithms to estimate the transceiver spectrum-access parameters and to characterize the propagation environment.

  • Patent number: 10314025
    Abstract: Systems and methods are provided for performing multi-user transmissions across different segments of a transmission medium. A connection between a first access point and a plurality of stations is established; wherein a first station of the plurality of stations detects that a primary channel of communication between the first access point and the plurality of stations is being used for transmission by a second access point. The first access point allocates a transmission channel to the first station to communicate with the first access point. The first access point determines whether an acknowledgement from the first station is received. In response to determining that the acknowledgement has been received, the first access point allocates a resource unit to the first station using the transmission channel. In response to determining that the acknowledgement has not been received, the first access point reallocates the first station to a different transmission channel.
