Abstract: The present disclosure provides techniques for reducing latency of periodic URLLC transmission and other critical data transmission with low latency requirements. To support periodic URLLC traffic, SPS with repetition is used. Before synchronization is achieved, the base station sends to the UE an SPS configuration for a periodic uplink data transmission. When the starting time of the data transmission is not known, the base station over-provisions SPS resources for the periodic data transmission. Based on the timing of the data transmissions, the base station adjusts the timing of the SPS configuration.

Abstract: Methods, systems, and devices for multicast wireless communications are described. A base station may configure a user equipment (UE) for providing feedback for multicast transmissions from the base station while the UE is in an inactive or idle mode.

A base station may configure a UE with multiple TA commands, each corresponding to a TA value and a set of channel metrics associated with group of cells including a serving cell of the UE. Based on measure channel metrics at the UE, the UE may determine a TA to use for multicast feedback. TA values may be determined using neural network modeling.

Abstract: The use of wireless backhaul poses special challenges for in-vehicle base stations. Users that are connected to an in-vehicle base station expect continuous service, even as the in-vehicle base station passes in and out of different wireless backhaul coverage zones, such as when a train passes from a train station with good coverage to a tunnel with poor coverage. The base station thus needs seamless backhaul handover. A system that enables an in-vehicle base station to receive continuous service across different backhaul coverage zones is needed. To solve this problem, a system enabling handover is described. The system involves double-tunneling mobile device data packets in an ESP-UDP IPsec tunnel encapsulated in a GTP-U tunnel. Traffic is transmitted from a mobile device to a specially configured base station that encapsulates mobile device data packets and sends them to the network via wireless backhaul using an LTE UE modem connection.

State-based controllers for the Clos networks and state-based methods to assign routes in are also discussed.
