  • RECESSED CONTACTS AT LINE END AND METHODS FORMING SAME
    Publication number: 20220359287
    Abstract: Embodiments include a contact structure and method of forming the same where the contact structure is deliberately positioned near the end of a metallic line. An opening is formed in an insulating structure positioned over the metallic line and then the opening is extended into the metallic line by an etching process. In the etching process, the line end forces etchant to concentrate back away from the line end, causing lateral etching of the extended opening. A subsequent contact is formed in the opening and enlarged opening.

  • ADAPTATION FRAMEWORK FOR UE POWER SAVING
    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.

  • UE GROUPING FOR PAGING ENHANCEMENT
    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.

  • METHODS AND APPARATUS TO REDUCE PACKET LATENCY IN MULTI-LEG TRANSMISSION
    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.
