  • Patent number: 10237039
    Abstract: A wireless network may implement a reduced bandwidth for control information transmitted and/or received on the wireless network. The reduced bandwidth may be used to avoid interference that may be detected from an in-band or adjacent channel. The reduced bandwidth may be used for transmission and/or reception of control information on a cellular or Wi-Fi channel. An eNB or an access point (AP) may signal to a wireless transmit/receive unit (WTRU) information associated with the reduced control channel, such as the power and/or the location of the channel in a frequency band. The control channel may be shifted to avoid a change in interference.

  • Patent number: 10153870
    Abstract: A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.

  • Patent number: 10153891
    Abstract: A method and apparatus for coexistence among wireless transmit/receive units (WTRUs) operating in the same spectrum are disclosed. A wireless transmit/receive unit (WTRU) may include a processor that receives a configuration of a coexistence gap pattern defining a pattern of transmission periods and silent periods for the WTRU. The processor may control the WTRU to transmit information during the transmission periods and to not transmit information during the silent periods of the coexistence gap pattern.

  • Publication number: 20180270815
    Abstract: Coexistence gaps may permit one radio access technology (RAT) to coexists with another RAT by providing period in which one RAT may be silent and another may transmit. Methods may account for the RAT traffic and for the presence of other secondary users in a channel. Methods may be provided to dynamically change the parameters of a coexistence gap pattern, such as the duty cycle, to adapt to both the RAT traffic and the presence of other secondary users. Methods may include PHY methods, such as synchronization signal (PSS/SSS) based, MIB based, and PDCCH based, MAC CE based methods, and RRC Methods. Measurements may be provided to detect the presence of secondary users, and may include reporting of interference measured during ON and OFF durations, and detection of secondary users based on interference and RSRP/RSRQ measurements.

  • Patent number: 10070431
    Abstract: Systems, methods, and apparatus may be used to provide assistance for connection procedures in a hierarchical network where macro cells may be operating in licensed spectrum while small cells may be operating in dynamic and shared spectrums, such as TVWS. This may be done, for example, to allow an LTE system performing carrier aggregation (CA) to reconfigure itself to change from a supplementary cell (SuppCell) in one dynamic and shared spectrum channel to a SuppCell in another dynamic and shared spectrum channel.

  • Patent number: 9992780
    Abstract: Methods and apparatus for shared access systems may be used to allow operation in three-tiered shared spectrum architecture. For example, a Shared Spectrum Manager (SSM) may organize spectrum segments. The SSM may communicate with access users of different priority and may use message exchanges to request spectrum, bid for spectrum, manage spectrum, or the like. The SSM may manage admission of access users (allocation of spectrum to users) and operation with a spectrum request that may be provided as a range between a minimum (guaranteed) and maximum quality of operation. The SSM may also manage the way an access user may use the assigned spectrum. Inter-SSM communication may be used in regions where multiple SSMs may exist (e.g. country borders). Accordingly, triggers for this inter-SSM communications and corresponding actions are also disclosed herein.

  • Patent number: 9967893
    Abstract: A system, apparatuses and methods are provided for communicating in an opportunistic band. Channels that are reserved for primary users are used by sensing devices when primary users are not present. A geo-location database is configured to store occupancy information of a channel and information associated with the primary user of the channel. The database includes information such as the type of primary user, and the expected occupancy time of a channel by a primary user. Sensing devices are categorized into different classes based on their sensing capability. A device capabilities database stores device classification information associated with the sensing devices attached to a dynamic spectrum management system.

  • Publication number: 20170325122
    Abstract: A method and apparatus may be used for network management via MAC measurements. The measurements may include WTRU uplink traffic loading measurement, and an AP service loading measurement. The measurements may be applicable to at least to layers 1 and 2 as applied to, for example, 802.11k in the context of OFDM and CDMA 2000 systems, but may be applicable to other scenarios as well. A method for determining and transmitting congestion information may be provided for a Wireless Local Area Network (WLAN) system. The method and apparatus may be used for managing congestion when congestion is detected. The method and apparatus may be used in wireless systems that use a Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) mechanism. The methods may be implemented in wireless transmit/receive units (WTRU)s and access points (AP)s of various forms.

  • Patent number: 9807778
    Abstract: Described herein are methods, metrics and apparatus for bandwidth allocation for cognitive radio. Information that needs to be passed between different components of a dynamic spectrum management (DSM) system for dynamic bandwidth allocation along with the corresponding interfaces is identified. Methods and associated metrics for measuring network performance, evaluating channel sensing results and handling various bandwidth allocation scenarios are presented. Also provided is an admission control mechanism for quality of service support. Alternate channel monitoring may be performed in the background so that when a new channel is needed, an alternate channel may be immediately allocated and service disruption to the DSM system is reduced. A channel may be dynamically assigned as the primary channel in multiple channel scenarios to support tasks such as transmission of acknowledgment frames.

  • Patent number: 9769692
    Abstract: A wireless transmit/receive unit (WTRU) and a dynamic spectrum management (DSM) engine are described. The WTRU includes a transceiver, a radio frequency (RF) spectrum sensing unit and a processing unit. The transceiver transmits over a wireless link. The RF spectrum sensing unit measures information indicative of usage of a spectrum by other devices. The processing unit detects a change in performance of the wireless link, controls the transceiver to transmit a notification to a DSM engine indicating that the change in the performance of the wireless link was detected on a condition that the processing unit detects the change in performance of the wireless link, and receives a sensing task request for the WTRU to measure the information indicative of the usage of the spectrum by other devices based on the notification transmitted to the DSM engine indicating that the change in the performance of the wireless link was detected.
