Abstract: A computer-readable storage medium that stores instructions for execution by one or more processors of a UE. The instructions to configure the UE for a streamlined transmission during low latency communications in a wireless network and to cause the UE to decode configuration signaling from a base station. The configuration signaling configures SR occasions for the UE. The UE detects availability of a UL data packet from an application layer, a size of the UL data packet being higher than a size of a TTI associated with a pre-defined slot boundary. An SR is encoded for transmission during one of the SR occasions, the SR including an indication based on the size. Control information is decoded in response to the SR, the control information including a scheduling grant based on the size of the UL data packet. The UL data packet is encoded for transmission using the scheduling grant.

Abstract: The present disclosure is related to multi-access traffic management in multi-access computing environments. A reliability enhancement engine (REE) operated by a multi-access multipath traffic manager identifies traffic flows that have high reliability requirements (“reliability flows”) and performs admission control for the reliability flows. The REE determines a coding rate (e.g., a redundancy factor) and traffic distribution strategies for the identified reliability flows. The REE applies cross-access network coding (NC) on the reliability flows, and handles multi-access acknowledgements and traffic pacing, which may involve multiplexing traffic of the reliability flows with non-high-reliability traffic. Other embodiments may be described and/or claimed.

Abstract: Systems and methods provide flow control for uplink traffic in an integrated access and backhaul network. A first relay node determines that its uplink buffer has reached an occupancy level higher than a pre-determined level. In response, the first relay node transmits, to a second relay node associated with the first relay node, a message indicating a buffer occupancy status of the uplink buffer of the first relay node.

Abstract: An apparatus and system for reducing URLLC latency are described. A single packet mode is described in which, when a packet arrives at the PDCP layer for transmission, an indication is sent to a scheduler with the expected size of the packet after ciphering. The packet is then sent to the RLC layer and concurrently submitted to the ciphering engine to enable ciphering to occur in parallel with the other activities. The scheduler determines the expected TB size for transmission of the packet by determining the size of the PDCP, MAC, and RLC headers. The scheduler matches the resource allocation for transmission to the expected TB size.

Abstract: A non-transitory computer-readable storage medium stores instructions for execution by one or more processors of user equipment (UE). The instructions cause the UE to encode a scheduling request (SR) for transmission to a base station during one of a plurality of SR occasions. The SR includes an indication based on a size of an uplink (UL) data packet. Control information received from the base station in response to the SR is decoded. The control information includes a scheduling grant based on the size of the UL data packet. The UL data packet is encoded for transmission using the scheduling grant. The UL data packet is encoded for transmission using the scheduling grant.
