Abstract: A method for predicting channel load. The method includes determining a first channel quality information (CQI) associated with a location and a first time point, predicting traffic flow data associated with the location and a second time point subsequent to the first time point, predicting a second CQI associated with the location and the second time point based on the first CQI and the predicted traffic flow, and selectively transmitting a message comprising the second CQI, the location, and the second time point to at least one transportation vehicle based on the second CQI. Also disclosed is a transportation vehicle and a road side unit (RSU) for performing the method.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may transmit, to a base station, a first uplink message including one or both of a protocol layer source identifier associated with a second UE or a request for a local identifier associated with the second UE. The first UE may receive, from the base station, a first downlink message including a downlink signal radio bearer (DL SRB) message, and the DL SRB message including one or both of the protocol layer source identifier associated with the second UE or the local identifier associated with the second UE in a downlink adaptation layer header of the DL SRB message. The first UE may transmit, to the second UE, in a sidelink adaptation layer header of a sidelink message, the local identifier associated with the second UE based in part on the received first downlink message.

Abstract: A system and communication method for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT), and for application to intelligent services based on the 5G communication and the IoT-related technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for processing a packet by a transmission device in a wireless communication system according to the present disclosure comprises the steps of: checking whether a data radio bearer (DRB) mapped to a quality of service (QOS) flow changes from a first DRB to a second DRB; and when the DRB changes from the first DRB to the second DRB, transmitting, to a reception device, information on a last packet transmitted through the first DRB in the QoS flow.

Abstract: Some embodiments provide a novel method for connecting one or more vehicles to a software defined wide area network (SD-WAN). The method deploys an edge router to operate in the vehicle, and configures the edge router to connect to several wireless network links (e.g., 5G cellular links) operating in the vehicle. In some embodiments, the different wireless network links are different mobile hotspot links provided by different telecommunication network providers (e.g., AT&T, Verizon, T-Mobile, Orange, etc.). The method configures the edge router to forward several data message flows from a device operating in the vehicle (e.g., a computer located in the vehicle or a machine (e.g., virtual machine, Pod, container, etc.) executing on a computer located in the vehicle) to the SD-WAN using the several telecommunications network links.

Abstract: A communication method and a communication device. A first donor node generates a first data packet, where the first data packet further includes first information. The first information indicates a donor node to which a destination node of the first data packet belongs, or indicates a network segment to which a destination node of the first data packet belongs, or indicates whether a network segment to which a destination node of the first data packet belongs is a network segment controlled by the first donor node. The first donor node sends the first data packet to the destination node first node.

Abstract: The present disclosure provides techniques for rate adaptation under congestion and latency constraints. The approaches described herein focus on aspects of latency, reliability, and power consumption instead of the traditional aspect of throughput. In an example, a method for rate adaptation is disclosed. The method may include determining whether to transmit a new packet or a retry packet. The method may also include reducing a maximum rate for a rate search in response to determining to transmit the retry packet. The method may further include transmitting the retry packet based on the reduced maximum rate.

Abstract: A terminal includes circuitry and a transmitter. The circuitry, in operation, determines a first transmission power for a first uplink signal and a second transmission power for a second uplink signal by prioritizing allocation of a transmission power to the second transmission power for the second uplink signal, responsive to, in a first transmission time interval (TTI) where the first uplink signal is transmitted, the second uplink signal being transmitted in a second TTI that is shorter than the first TTI. The transmitter, in operation, transmits the first uplink signal with the determined first transmission power and transmits the second uplink signal with the determined second transmission power.

Abstract: In a first aspect, a communication control method is used in a cellular communication system. The communication control method includes transmitting, by a first relay node subordinate to a first donor base station, a first packet to a second donor base station different from the first donor base station. The communication control method includes forwarding, by the second donor base station, the first packet to the first donor base station by using a path for data forwarding, and transmitting, by the first donor base station, the first packet to a network.
