    摘要： Systems and methods for implementing various metrics for in integrated IAB networks are disclosed. A child IAB node may determine metrics regarding one or more of its data flows and report these metrics to an upstream IAB node (that is a parent node and/or an IAB donor). The upstream node may determine a data flow prioritization configuration using these metrics that it either uses itself or sends back to the child IAB node or another IAB node of the IAB network for use there. Metrics discussed include a number of hops metric, an aggregate throughput per BH RLC channel ID (or per routing ID) metric, a fairness index per BH RLC channel ID (or per routing ID) metric, a packet drop metric, and a per-hop latency for aggregated traffic per BH RLC channel ID (or per routing ID) per IAB node metric.

    摘要： Systems and methods for using integrated access and backhaul (IAB) nodes configured to provide multi-access edge computing (MEC) functionality are disclosed herein. An TAB node includes a distributed unit (DU) having a local application instance of a MEC-enabled application. The local application instance is configured for communication with a first user equipment (UE) connected to the TAB node. A mobile termination functionality (MT) of the TAB node uses a packet data convergence protocol (PDCP) layer to transport data of the local application instance between the MT and an IAB donor. Further, data of the local application instance is transported between the UE and the TAB node via one of a variety of methods, including the use of a second PDCP layer at the DU (and optionally the use of service data adaptation protocol (SDAP) layers at each of the DU and the MT), and/or via sidelink.

    摘要： Systems, methods, and circuitries are provided for supporting aggregated retransmissions. In one example, a method includes receiving control information that indicates resources including one or more slots for communication of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) transmission that includes at least one PDSCH/PUSCH retransmission A slot group to which a selected one of the one or more slots belongs is identified. The method includes configuring operation to receive the PDSCH transmission or to transmit the PUSCH transmission based on the resources. In response to determining that a PDSCH/PUSCH retransmission of the PDSCH/PUSCH transmission is scheduled for a slot outside the identified slot group, operation is configured to provide hybrid automatic repetition request (HARQ) feedback based on PDSCH/PUSCH retransmissions scheduled for slots within the identified slot group, wherein the HARQ feedback is not based on PDSCH/PUSCH scheduled for slots outside the identified slot group.

    摘要： Techniques discussed herein can facilitate beam management for non-terrestrial networks (NTN). One example aspect is A baseband processor, comprising: a memory interface; and processing communicatively coupled to the memory and transceiver interface and, while connected to a base station (BS) within a cell of a non-terrestrial network (NTN) and, where the cell comprises a plurality of bandwidth parts (BWPs) associated with a plurality of beams, configured to perform operations comprising: receiving a signaling from the base station (BS) comprising a channel state indicator reference signal (CSI-RS) configuration associated with a first BWP of the plurality of BWPs, where the CSI-RS configuration comprises a beam measurement configuration for the plurality of beams, switching from a second BWP of the plurality of BWPs to the first BWP according to the CSI-RS configuration and measure one or more of the plurality of beams according to the beam measurement configuration; and generating a measurement report that includes a layer 1 reference signal received power (L1-RSRP) measurement from the measured one or more of the plurality of beams.
