Publication number: 20140161002Abstract: 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.Type: ApplicationFiled: February 7, 2012Publication date: June 12, 2014Inventors: Jean-Louis Gauvreau, Martino M.

Publication number: 20140080535Abstract: 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.Type: ApplicationFiled: September 19, 2013Publication date: March 20, 2014Inventors: Jean-Louis Gauvreau, Rocco Di Girolamo, Athmane Touag, Martino Freda, Mihaela C.

Publication number: 20120294168Abstract: 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.Type: ApplicationFiled: November 1, 2011Publication date: November 22, 2012Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Martino M.

Publication number: 20120163309Abstract: 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.

Publication number: 20120120892Abstract: A dynamic spectrum management (DSM) system includes a plurality of stations and a central entity. A plurality of different radio access technologies are deployed in the DSM system and the central entity coordinates and manages wireless communications in the network. A direct link station receives a beacon periodically from an access point (AP). The direct link station may receive a direct link synchronization message from the AP indicating that a following target beacon transmission time (TBTT) is a synchronization TBTT (STBTT). The direct link station may silence the direct link channels during the STBTT. The direct link station may perform carrier sense multiple access (CSMA) on a primary channel of the direct link to get an access to all direct link channels.
