Patent number: 11032870Abstract: Current wireless networks do not allow machine type communication (MTC) devices to have long discontinuous reception (DRX) cycles or sleep lengths. A long DRX cycle may allow MTC systems and devices to operate with much longer DRX/Sleep cycles/periods. This may facilitate the MTC operations for infrequent system access or infrequent system reaching (e.g. paged once in a week) with no or low mobility and may allow MTC devices to sleep for a long time with low power consumption.Type: GrantFiled: June 18, 2018Date of Patent: June 8, 2021Assignee: InterDigital Patent Holdings, Inc.Inventors: Ulises Olvera-Hernandez, Ghyslain Pelletier, Peter S.

Publication number: 20210014798Abstract: A method for reporting power headroom is disclosed. Power headroom may be reported across all carriers (wideband), for a specific carrier, or for a carrier group. The formula used to calculate the power headroom depends on whether the carrier (or a carrier in the carrier group) has a valid uplink grant. If the carrier or carrier group does not have a valid uplink grant, the power headroom may be calculated based on a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.Type: ApplicationFiled: September 18, 2020Publication date: January 14, 2021Applicant: InterDigital Patent Holdings, Inc.Inventors: Guodong Zhang, Erdem Bala, Philip J.
