Patent number: 12426009Abstract: Systems and methods of increasing paging opportunities when the unlicensed band is used are described. The gNB sends an RRC message that indicates multiple monitoring occasions in a paging occasion of a paging frame. The UE monitors a monitoring occasion of a PO to determine whether a PDCCH with a P-RNTI has been received in an unlicensed band. If such a PDCCH is received, the UE decodes PD SCH information in the PDCCH to determine whether the P-RNTI is a P-RNTI of the UE. If so, the UE avoids monitoring subsequent monitoring occasions of the PO. If the PDCCH does not contain a P-RNTI, the UE continues to monitor other monitoring occasions within the PO.Type: GrantFiled: September 22, 2023Date of Patent: September 23, 2025Assignee: Apple Inc.Inventors: Anthony Lee, Seau S. Lim, Yongjun Kwak, Dae Won Lee, Youn Hyoung Heo, Lopamudra Kundu

Patent number: 12408224Abstract: Systems and methods of in-sync/out-of-sync (IS/OOS) determination in the unlicensed band are described. Reference signals are measured on the unlicensed band. If the UE determines that at least one of the reference signals is missing, the IS/OOS condition is evaluated on that basis. If the missing signals are ignored when determining the IS/OOS condition, and the IS/OOS condition is unable to evaluated, the L1 sends an indication to the RRC layer. If the number of indications exceeds a threshold, the UE performs re-establishment or sends a report to the base station for adjustment of the reference signal resources. If the missing signals are counted, the missing signals are weighted based on proximity to the noise floor or a number of adjacent signals that are missing.Type: GrantFiled: September 16, 2019Date of Patent: September 2, 2025Assignee: Apple Inc.Inventors: Seau S.

Patent number: 12336008Abstract: Techniques are provided for determining and processing uplink listen before talk (LBT) failures, including the determination of a consistent and systematic LBT failure associated with uplink transmissions in new radio (NR) operating over unlicensed spectrum. For example, a user equipment (UE) identifies a plurality of transmission occasions to be performed by the UE over the unlicensed spectrum. The UE further performs a plurality of listen before talk (LBT) procedures associated with respective ones of the plurality of transmission occasions to be performed by the UE, and tracks a number of LBT failures during the performance of the plurality of LBT procedures, wherein a LBT failure occurs due to a channel used for the associated LBT procedure being busy or when an LBT backoff is still running from a previous LBT failure. The UE further implements a recovery procedure in response to the LBT failures exceeding a predetermined threshold within a predetermined time period.Type: GrantFiled: May 1, 2020Date of Patent: June 17, 2025Assignee: Apple Inc.Inventors: Anthony Lee, Seau S.

The gNB sends an RRC message that indicates multiple monitoring occasions in a paging occasion of a paging frame. The UE monitors a monitoring occasion of a PO to determine whether a PDCCH with a P-RNTI has been received in an unlicensed band. If such a PDCCH is received, the UE decodes PDSCH information in the PDCCH to determine whether the P-RNTI is a P-RNTI of the UE. If so, the UE avoids monitoring subsequent monitoring occasions of the PO. If the PDCCH does not contain a P-RNTI, the UE continues to monitor other monitoring occasions within the PO.Type: GrantFiled: September 25, 2019Date of Patent: March 4, 2025Assignee: Apple Inc.Inventors: Anthony Lee, Seau S.

Publication number: 20240373461Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to memory, where to configure the UE for communication of data in a New Radio-Unlicensed (NR-U) spectrum, the processing circuitry is to decode RRC signaling from a base station. The RRC signaling includes configuration information to configure a listen-before-talk (LBT) timer and a scheduling request (SR) prohibit timer. An LBT procedure is performed while the LBT timer is activated. An SR is encoded for transmission to the base station, based on detecting an unoccupied transmission resource within the NR-U spectrum during the LBT procedure. The SR transmission activates the SR prohibit timer. An uplink grant from the base station is decoded in response to the SR, the uplink grant received while the SR prohibit timer is activated. A buffer status report (BSR) is encoded for transmission to the base station based on the uplink grant.Type: ApplicationFiled: July 19, 2024Publication date: November 7, 2024Inventors: Anthony Lee, Seau S.

Patent number: 12137415Abstract: A user equipment (UE), or other network component can operate to generate listen-before-talk (LBT) operations in order to manage power consumption by configuring the discontinuous reception (DRX) in a dynamic manner. The UE can configure an extended active time for the DRX based on whether the LBT is successful and an acquisition channel indication from a base station, e.g., a next generation NodeB (gNB). The UE can operate aperiodic wakeup occasions with or independently of periodic DRX on-durations to better manage power while monitoring a channel for unlicensed carrier communications.Type: GrantFiled: March 26, 2020Date of Patent: November 5, 2024Assignee: Apple Inc.Inventors: Murali Narasimha, Seau S.
