Publication number: 20180152268Abstract: 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: January 29, 2018Publication date: May 31, 2018Applicant: InterDigital Patent Holdings, Inc.Inventors: Jean-Louis Gauvreau, Martino M.

Publication number: 20170149490Abstract: Methods and wireless devices are described. A method includes a wireless device transmitting to wireless transmit/receive units (WTRUs) by being scheduled by the base station or using a pool of radio resources, which is for any of a plurality of wireless devices to use for transmission to WTRUs. On a condition that the wireless device is to be scheduled by the base station, the wireless device receives scheduling information for transmission to a WTRU having a group radio network terminal identifier (RNTI) and transmits to the WTRU in response to the received scheduling information. The scheduling information for transmission to the base station uses a different RNTI. On a condition that the wireless device is to use the pool of radio resources for transmission to a WTRU, the wireless device transmits to the WTRU without being scheduled by the base station using the pool of radio resources.Type: ApplicationFiled: December 16, 2016Publication date: May 25, 2017Applicant: InterDigital Technology CorporationInventors: Sana Sfar, Alexander Reznik, Prabhakar Chitrapu, Zinan Lin, Mohammed Sammour, Ana Lucia A.

Publication number: 20160150416Abstract: Systems and methods are provided for coexistence management service for licensed and unlicensed spectrum sharing. A coexistence system may include a coexistence manager (CM) that may provide resource allocation services for a coexistence enabler (CE). CMs may negotiate with each other to resolve coexistence issues via directly or indirectly through a coexistence discovery and information server (CDIS). A channel may be exclusively used by a CE network. The networks may mitigate interference by avoiding use of the same channels. A channel may be shared by multiple CE networks. In co-channel sharing, the networks may mitigate interference via power management. Bidding processes may be implemented directly via competing CMs, for example via open or silent token auction. Bidding processes among competing CMs may be managed by a third party entity, for example a CDIS, for example via open or silent token auction.Type: ApplicationFiled: January 29, 2016Publication date: May 26, 2016Applicant: InterDigital Patent Holdings, Inc.Inventors: Chunxuan Ye, Scott Laughlin, Jean-Louis Gauvreau, Zinan Lin, Martino M.
