Abstract: Apparatus and methods are provided for UE-assisted tethering report. In one novel aspect, UE-assisted tethering report is generated with UE-assisted procedure based on latency measurement configuration. In one embodiment, the UE-assisted tethering report includes one or more elements comprising one bit to inform the activation of tethering mode, latency of packet transmission, and other side-information related to tethering path. In one embodiment, the UE-assisted procedure is inserting a measurement timestamp or recording timing of a predefined transport block (TB) of the packet. In another novel aspect, the UE performs a jitter measurement for an extended reality (XR) traffic, sends a UE-assisted information report for an end-to-end path of the XR traffic based on the jitter measurements, wherein the UE-assisted information includes one or more elements comprising jitter information and burst arrival time.

Abstract: LWA (LTE/WLAN Aggregation) is a tight integration at radio level which allows for real-time channel and load aware radio resource management across WLAN and LTE to provide significant user perceived throughput (UPT) improvement. When enabling LWA, packets are routed to a base station (eNB) for performing PDCP functionalities as an LTE PDU. Afterwards, the eNB can dispatch the PDU either delivered over LTE link or WLAN link. The UPT improvement depends on how the eNB dispatches the PDU over LTE link or WLAN link. In one novel aspect, the eNB can acquire channel information, load information, and throughput estimation regarding with WLAN link and LTE link. As a result, the eNB can optimize UPT and LWA PDU dispatching algorithm.
Abstract translation: LWA（LTE / WLAN聚合）是无线电级别的紧密集成，其允许跨WLAN和LTE的实时信道和负载感知无线电资源管理，以提供显着的用户感知吞吐量（UPT）改进。 当启用LWA时，分组被路由到用于执行作为LTE PDU的PDCP功能的基站（eNB）。 之后，eNB可以通过LTE链路或WLAN链路发送PDU。 UPT的改进取决于eNB如何通过LTE链路或WLAN链路分派PDU。 在一个新颖的方面，eNB可以获取关于WLAN链路和LTE链路的信道信息，负载信息和吞吐量估计。 因此，eNB可以优化UPT和LWA PDU调度算法。

Abstract: A method of radio link monitoring (RLM) can include performing a physical sidelink shared channel (PSSCH) transmission over a radio link between a Tx UE and a Rx UE in sidelink communications, receiving a HARQ feedback status corresponding to the PSSCH transmission from a physical layer, incrementing a count of a number of consecutive HARQ failure indications (e.g., represented by HARQ DTX) received for PSSCH transmissions over the radio link between the Tx UE and the Rx UE by 1 when the received HARQ feedback status is a HARQ failure indication, declaring a radio link failure (RLF) for the radio link between the Tx UE and the Rx UE when the count of the number of consecutive HARQ failure indications reaches a threshold, and resetting the count of the number of consecutive HARQ failure indications to 0 when the received HARQ feedback status is not a HARQ failure indication.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. In certain configurations, the UE establishes a connection supporting an extended reality (XR) application service with a base station. The UE reports, to the base station, a delay status report (DSR) to indicate a buffer size for data to be transmitted to the base station. The DSR includes timing information. The UE receives a configuration instruction from the base station. The UE configures resources on the UE according to the configuration instruction to transmit the data to the base station.

Abstract: Mechanism of relay UE discovery and relay UE selection and reselection for remote UE data transmission with a serving base station via relay UE is proposed. A method operable for relay UE selection and reselection of remote UE is provided. The UE considers additional criteria such as relay load other than purely radio signal quality (e.g., RSRP) criteria. The relay load can serve different purpose for relay UE and remote UE. The relay load can be the criteria for UE to become a relay UE or not. It can be the criteria for a remote UE to select another UE as its relay UE.

Abstract: A method of UE prioritizing and multiplexing simultaneous sidelink relay data for Logical Channel Prioritization (LCP) procedure in new radio (NR) system is proposed. UE can provide traffic prioritization based on traffic category when UE has simultaneous traffic from more than one traffic categories to transmit. The sidelink relay traffic prioritization is then used for transmission interface and resource selection, and data multiplexing prioritization on the basis of sidelink relay architecture. Specifically, a method on how to perform the corresponding logical channel prioritization (LCP) operation for MAC PDU multiplexing is provided. LCP restriction is considered to determine which classes of traffic can be multiplexed into the same MAC PDU together. Priority of multiplexing is also applied to determine the order and the amount of traffic to be included in the MAC PDU.

Abstract: A tagging mechanism supporting different QoS categories for IP/Port services in a cellular radio network is proposed. Tags are used to differentiate different types of services and corresponding QoS requirements. At the sender side, the sender of the IP packets is able to distinguish different types of services by tagging one or multiple bits for finer QoS control. For downlink IP traffic, the tagging function can be done at the base station. For uplink IP traffic, the tagging function can be done at the UE. At the receiver side, the receiver delivers the IP packets using out-of-sequence delivery for delay sensitive packets. With tagging and out-of-sequence delivery, the delay sensitive packets can reduce CN latency and transmission latency.
