Patent number: 11239901Abstract: Methods and apparatus are described. A wireless transmit/receive unit (WTRU) includes a transceiver and a processor operatively coupled to the transceiver. The transceiver and the processor establish a connection with a first wireless network node and a second wireless network node. The transceiver and the processor also receive power configurations and timing advances from the first wireless network node independently of the second wireless network node. The transceiver and the processor also simultaneously receive downlink signals from both the first wireless network node and the second wireless network node. The downlink signals are independently scheduled by a scheduler of the first wireless network node and a scheduler of the second wireless network node.Type: GrantFiled: April 5, 2019Date of Patent: February 1, 2022Assignee: InterDigital Technology CorporationInventors: Sana Sfar, Alexander Reznik, Prabhakar Chitrapu, Zinan Lin, Mohammed Sammour, Ana Lucia A. Pinheiro, Mihaela Beluri, Chunxuan Ye, Yogendra Shah, Gregg A. Charlton, Guodong Zhang, Khushali N. Manseta, Ruiyuan Hu

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: 9537560Abstract: A method and apparatus for wireless communications is disclosed. Channel state information (CSI) for a plurality of network nodes is transmitted. Grant information is received from at least one network node of the plurality of network nodes. The grant information is based on the transmitted CSI and includes an indication of a cooperative scheme. A plurality of beam-formed signals, including data from each of the plurality of network nodes, is received in response to the received grant information. The same data is received from each of the plurality of network nodes.Type: GrantFiled: January 20, 2016Date of Patent: January 3, 2017Assignee: InterDigital Technology CorporationInventors: Sana Sfar, Alexander Reznik, Prabhakar Chitrapu, Zinan Lin, Mohammed Sammour, Ana Lucia A.
