Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A base station may receive from user equipment device (UE) a random access initiation message, having a characteristic that is configured to indicate to the base station a requested size of a subsequent uplink grant to be provided by the base station for transmission of uplink data by the UE. For example, the characteristic may include a predetermined preamble included in the random access initiation message, such that a requested grant size is indicated by which preamble the UE selects from a plurality of possible preambles. As another example, the characteristic may include which RACH occasion is selected by the UE to transmit the random access initiation message. In response, the base station may allocate resources for use by the UE based on the characteristic.

Abstract: 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.

Abstract: A network may authenticate a user equipment (UE) to access an edge data network. The network generates a first credential based on a second credential, the second credential generated for a procedure between the UE and a cellular network corresponding to the network component, receives an identifier associated with the first credential from a further network component in response to the UE transmitting an application registration request to a server associated with an edge data network and retrieves the first credential based on the identifier. The network also receives a multi-access edge computing (MEC) authorization parameter, verifies the MEC authorization parameter and transmits an authentication verification response to a second network component.

Abstract: Systems, methods, and devices are provided for performing cell selection or reselection in networks that include earth moving beams. In one example, a method includes receiving, via a satellite, control information transmitted by a base station indicating that a beam associated with a cell ID has been redirected; in response, measuring a beam strength of the redirected beam; and performing cell re-selection based on the measured beam strength.

Abstract: 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.
