Publication number: 20200037254Abstract: Techniques for uplink power control (e.g., for New Radio (NR)) are disclosed. A wireless transmit/receive unit (WTRU) may determine that the WTRU is to perform a first and a second transmissions using a first and a second transmission beams. The WTRU may determine an uplink transmission power for one or more of the first or second transmissions. For example, if the angular separation of the first and the second transmission beams is greater than a first separation threshold, the WTRU may determine the uplink transmission power having a first maximum power level parameter and a second maximum power level parameter. If the angular separation of the first and the second transmission beams is less than a second separation threshold, the WTRU determine the uplink transmission power having a shared maximum power level parameter. The WTRU may transmit Antenna array the first and second transmissions using the first and second transmission beams, respectively.Type: ApplicationFiled: September 26, 2017Publication date: January 30, 2020Inventors: Virgil Comsa, Paul Marinier, J.

Publication number: 20170367107Abstract: Methods and apparatus for mitigating in-device interference are described. The methods may include an in-device interference event (e.g. an interference situation), and the processing of events may depend on the priority of the technologies. A handover to another frequency or radio access technology (RAT) may occur in case a co-existing technology may be activated. The network may signal to the device a list of frequencies or RATs that it may be allowed to measure and handoff to. A network may provide a scaling value that the device may use to speed up reaction to the interference. The device may apply a scaling factor to an “out of synch’ counter and/or the radio link failure (RLF) tinier used for the RLF procedure. The device may apply different scaling factors for the measurements and time to trigger events. The device may trigger a report to the network requesting gaps for an alternate RAT.Type: ApplicationFiled: September 1, 2017Publication date: December 21, 2017Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Virgil Comsa, Diana Pani, Christopher R.
