  • Publication number: 20230038500
    Abstract: A method of enhanced discontinuous reception (DRX) operation for additional power saving is proposed. A UE is allowed to not restart the DRX inactivity timer if there is no uplink data available to transmit, even when the UE receives a dynamic uplink grant. The UE thus can terminate the DRX active time and go to sleep earlier when the inactivity timer expires. The UE can send a sync message to inform the gNB of “not restarting the inactivity timer”, or the UE can send information for the gNB to know when the DRX active time will be terminated. Furthermore, the UE is allowed to request for dynamic DRX active time termination, e.g., to dynamically request for terminating the DRX active time earlier by sending a request or a notification to the network.

  • Patent number: 11528597
    Abstract: A method for UE capability reduction on a per-component-carrier or a per-frequency-range basis is proposed. In NR networks, UE may be operating in multiple frequency ranges (FRs) and configured with multiple component carriers (CCs) under carrier aggregation. UE can detect an overheating problem due to the RF activity supporting high bandwidth or high MIMO rank on a specific FR or a specific CC. Accordingly, UE indicates to the network a preference for a capability reduction on the specific FR or the specific CC, e.g., a reduced number of carriers, a reduced maximum bandwidth, or a reduced MIMO rank. Such per-FR or per-CC request allows UE to restrict or reduce its capability in a manner that is specific to certain component carriers and/or certain frequency ranges rather than to a global capability reduction that affects all carriers/frequencies.

  • Patent number: 11528656
    Abstract: A method of multiplexing logical channels (LCHs) in configured grants (CG) to enable faster transmission of high priority data in 5G New Radio-Unlicensed (NR-U) is proposed. Two options of imposing a CAPC-based restriction rule on multiplexing a low priority LCH with a high priority LCH are provided. In a first option, a threshold CAPC value is configured via RRC signaling. Data belonging to LCH having a priority lower than the CAPC threshold is not allowed to be multiplexed with data belonging to LCH having a priority higher than the CAPC threshold. In a second option, each CAPC has a flag indicating if the CPAC can have reduced priority via RRC signaling. If the flag is set for the CAPC, then data belonging to LCH assigned with the CAPC cannot be multiplexed with data belonging to lower priority LCHs.

  • Patent number: 11412549
    Abstract: This innovation describes methods for an NR-based, LEO Non-Terrestrial Networks (NTN) to improve handover process by sending broadcast or group-cast downlink handover (HO) Command message to all (or group of) UEs in the coverage area (cell or beam-spot) of the LEO satellite. Subsequently, on receiving the broadcast (or group-cast) HO Command message, all the UEs in the source cell transmit HO Complete message to the source cell of the LEO-NTN. In order to reduce or avoid heavy Random Access (RA), generating from all the UEs, the LEO-NTN can either send Contention Free Random Access (CFRA), or instruct the UE to perform a random backoff before sending the uplink HO Complete message. Moreover, improvements to configure Conditional Handover (CHO) and delaying the transmission of HO Complete message are also provided.

  • Publication number: 20220132573
    Abstract: A method for determining Listen Before Talk (LBT) type and Channel Access Priority Class (CAPC) for signaling message transmission over signaling radio bearers (SRBs) in 5G New Radio-Unlicensed (NR-U) is proposed. A user equipment (UE) generates an SRB message to be transmitted to a serving base station over a control channel. Before the uplink (UL) transmission of an UL PDU containing the SRB message, the UE performs an LBT procedure using a set of LBT parameters associated with a CAPC value. In one embodiment, the CAPC is provided by the base station via an UL grant contained in a downlink control information (DCI). In another embodiment, the CAPC is determined by the UE based on an SRB type of the SRB message.

  • Publication number: 20220116839
    Abstract: Methods and apparatus are provided for UE-triggered handover and early preparation with coexistence of the network-triggered handover. In one novel aspect, the UE is configured early measurement report configuration, receives an early handover command from the serving base station with a handover candidate cell list, monitors handover triggering conditions for each candidate cell on the handover candidate cell list based on a UE-triggered handover configuration and performs the UE-triggered handover to a candidate cell when the corresponding triggering condition is met for the candidate cell. In one embodiment, the UE receives a network-triggered handover command to a target cell, suspends the UE-triggered handover configuration and performs the network-triggered handover to the target cell. The UE discards the UE-triggered handover configuration upon success of the network-triggered handover and resumes the UE-triggered handover configuration upon failure of the network-triggered handover.

  • Patent number: 11265845
    Abstract: A method to improve paging process by including additional backup paging opportunities in new radio unlicensed (NR-U) systems is proposed. To cope with the downlink transmission impairments arising from possible listen-before-talk (LBT) failures, NR-U user equipment (UE) can listen the additional paging opportunities (POs) to get the paging message. In an efficient mechanism, additional backup paging opportunities are configured while minimizing the UE's power consumption. The invention also reduces UE's power consumption by configuring short and micro sleep cycles between successive backup paging opportunities. In addition, to avoid continuous listening to the backup paging opportunities, paging monitoring can be suspended for a UE if the LBT is successful and the paging is not intended for the UE.

  • Publication number: 20220058971
    Abstract: Aspects of the present disclosure provide methods, apparatuses, and systems for dynamically adjusting a breathing entrainment based on whether a user is stressing or relaxing. According to an aspect, a first target breathing period is selected, and a guiding stimulus configured to alter a current breathing period of the user towards the first target breathing period over an interval of time is output. One or more relaxation biometrics are measured and analyzed to determine whether the user is stressing or relaxing. Based on whether the user is relaxing or stressing, at least one of the guided stimulus and the first target breathing period are adjusted, where the first target breathing period is adjusted to a second target breathing period different from the first target breathing period. By making adjustments based on whether a user is relaxing or stressing, the breathing entrainment is more effective and comfortable for users.

  • Publication number: 20220039194
    Abstract: Apparatus and methods are provided for connectionless data transfer. In one novel aspect, the UE in INACTIVE state initiates one or more data transmissions without RRC connection upon determining one or more preconfigured transmission conditions. The UE restores an INACTIVE AS context, establishes UL resources, and performs connectionless data transmissions. The UE monitors one or more preconfigured fallback conditions for fallback procedures and monitors stop conditions for suspension/stopping procedures. In one embodiment, the UL resources for the one or more data transmission are preconfigured configuration grant (CG) resources from the network. In one embodiment, the preconfigured UL resource is used for the data transmission only when the TA is valid. When the TA is not valid, the UE performs RA procedure and either uses the preconfigure resource or continues the one or more data transmissions by monitoring PDCCH with C-RNTI.

  • Publication number: 20220007239
    Abstract: An efficient handover mechanism in New Radio Unlicensed (NR-U) is proposed. NR-U gNB will provide measurement object configuration and report configuration to include Received Signal Strength Indication (RSSI) or Channel Occupancy (CO) or some other channel load metrics. NR-U UE will use the measurement object configuration to measure the neighboring cells and subsequently report the measured RSSI/CO/channel load metrics of the neighboring cells to the source gNB using the report configuration. The report configuration will include Channel Utilization of the unlicensed network (e.g., WLAN) and Channel Availability of neighboring NR-U cells. This will improve the handover performance in NR-U, as a NR-U neighboring cell can be heavily loaded by different unlicensed nodes, e.g., WiFi nodes.
