Patent number: 10270518Abstract: 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: GrantFiled: December 16, 2016Date of Patent: April 23, 2019Assignee: InterDigital Technology CorporationInventors: Sana Sfar, Alexander Reznik, Prabhakar Chitrapu, Zinan Lin, Mohammed Sammour, Ana Lucia A.

Patent number: 10050762Abstract: A dynamic spectrum management (DSM) engine may determine the channel quality of one or more channels associated with the DSM engine when packets are not being transmitted over the channels. For example, the DSM engine may trigger a channel quality measurement on a non-primary channel on a condition that a predetermined period of time has lapsed since the last activity associated with the non-primary channel. Channel quality measurement may be triggered via a data sending event on the non-primary channel such as sending a data frame on the non-primary channel. The DSM engine may perform respective quality measurements on multiple channels and store the respective quality values in a database. Time-averaged channel qualities for the channels may be computed based on the stored quality values for computing transmit power distribution of across the channels.Type: GrantFiled: September 24, 2013Date of Patent: August 14, 2018Assignee: InterDigital Patent Holdings, Inc.Inventors: Jane Mack, Francois Periard, Fred M.
