  • Publication number: 20230108646
    Abstract: A method of providing early paging indication (PEI) for power consumption enhancements in a 5G/NR network is proposed. Under the novel paging reception procedure with PEI, UE can skip PO monitoring if PEI indicates negative. The UE main receiver is typically turned on in every paging cycle, for LOOP, MEAS, and PEI reception. However, if PEI indicates no paging, then UE can turn off its main receiver right after performing measurements. Since PEIs are always transmitted and are located near synchronization signal block (SSB) bursts, power saving can be achieved not only for PO monitoring but also for light sleep between the last SSB/PEI and the PO monitoring gap and state transitions, when no UE in the UE group is paged.

  • Patent number: 11611921
    Abstract: Aspects of the disclosure provide a method and an apparatus for performing a bandwidth part (BWP) switching process within different switching delays. For example, the apparatus can include receiving circuitry and processing circuitry. The receiving circuitry can receive from a BS a signaling indicating a change to a BWP configuration of the UE. The processing circuitry can perform a BWP configuration switching process based on the change to the BWP configuration to switch an active BWP configuration to a new BWP configuration, and monitor data transmission from the BS with the new BWP configuration either after a first predefined switching delay when the change to the BWP configuration includes at least one of a predefined set of BWP configuration parameters or after a second predefined switching delay when the change to the BWP configuration does not include any one of the predefined set of BWP configuration parameters.

  • Publication number: 20220279373
    Abstract: A method of UE power profile adaptation to traffic and UE power consumption characteristics based on power profile is proposed. In one preferred embodiment, hybrid of bandwidth part (BWP) and power profile is proposed. UE is configured with multiple BWPs and each BWP includes a set of power profiles. Two types of adaptation triggering can be used, a first type of trigger is based on power saving signals sent from the network, and the second type of trigger is based on timers. When the traffic characteristic for UE changes, the network can send a power saving signal to UE to trigger power profile adaptation, e.g., BWP+power profile switching. When traffic has been digested and becomes sporadic, then power profile adaptation can be triggered based on timers, e.g., a timer for BWP adaptation and another timer for power profile adaptation.

  • Publication number: 20220232514
    Abstract: A method of providing paging early indication (PEI) for power consumption enhancements in a 5G/NR network is proposed. In accordance with one novel aspect, UE subgrouping is used to indicate whether some UEs (a subgroup) among those UEs monitoring the same paging occasion needs to read paging. The UE subgroup can be grouped based on different factors, e.g., power consumption profiled (PCP), or paging probability. The UE subgroup has a reduced number of UEs, with a reduced false alarm rate for paging, at thus a reduced power consumption. In one preferred embodiment, the PEI contains a bitmap, each bit indicates if a subgroup of UEs monitoring the same PO needs to read paging.

  • Publication number: 20220201786
    Abstract: A method of providing UE-initiated PDCP status report to reduce packet latency under Multi-RAT Dual Connectivity (MR-DC) is proposed. UE initializes PDCP status report based on some predefined condition configured by the network. The PDCP status report indicates which PDCP SDU is still not received by the UE via one radio link control (RLC) entity, and the network can retransmit the missing PDCP SDU via another RLC entity quickly. The network can enable/disable the PDCP status report via PDCP control PDU or via radio resource control (RRC) signaling. The PDCP status can be used for re-transmission of PDCP SDU on another RLC entity. The PDCP status can also be used as an indication of issues on one RLC entity, resulting in duplication being activated thereafter. The PDCP status report should be sent to the RLC entity that does not suffer from the PDCP packet loss.
