A communication method and a communication apparatus are provided, which relate to the field of communication technologies. The communication apparatus includes a communication protocol module and a QUIC module. The communication protocol module is configured to send a first request to establish a first PDU session for a first data network, receive a first response indicating that the first PDU session is successfully established, and after receiving the first response, send, to the QUIC module, a first notification including a first IP address. The QUIC module is configured to, after receiving the first notification, send, to an application server of the first data network, a second request to establish a first QUIC connection, and receive a second response that indicates that the first QUIC connection is successfully established. An IP address on a terminal device side of the first QUIC connection is the first IP address.

A communication device mounted on a vehicle and an operation method of the communication device are provided. The communication device performs a connection with a communication terminal included in a vehicle stopped or driving in a vicinity of the vehicle via device-to-device communication, provide subscriber identity module (SIM) information to the connected communication terminal, request execution of a communication relay function from the communication terminal, and in response to a communication relay function acceptance signal being received from the communication terminal, transmit and receive data to and from the base station by using the communication terminal as a communication relay.

A base station (BS) comprising a processor configured to perform operations is described. In an exemplary embodiment, the operations include receiving an initial data from a UE is in a RRC_INACTIVE while the UE does not transition from the RRC_INACTIVE state to a RRC_CONNECTED state. In addition, the operations include transmitting a physical downlink control channel (PDCCH) for a UE dedicated scheduling for a transmission or reception of a subsequent data during an active period, while the UE is in the RRC INACTIVE state. Furthermore, the operations include receiving or transmitting the subsequent data transmission based on the dedicated scheduling. The operations additionally include transmitting one or more configurations for the transmission or reception of the subsequent data. The one or more configurations is transmitted as part of the RRC release message. The one or more configurations is transmitted as part of a System Information Block (SIB).

A method and apparatus for data transfer in RRC_INACTIVE state is provided. Method for data transfer in RRC_INACTIVE state includes transmitting a UECapabilityInformation, receiving a RRCRelease the RRC release message includes a first information for a second resume procedure, receiving a system information the system information includes a first threshold and a second threshold, initiating a second resume procedure and cancelling triggered PHR.

A method and apparatus for support of Mobile-Terminated Small Data Transmission (MT-SDT) considering Central Unit (CU)-Distributed Unit (DU) split is provided. A receiving gNB receives a Radio Access Network (RAN) paging message from a last serving gNB. The RAN paging message includes an MT-SDT indication informing that a MT-SDT is supported. The receiving gNB transmits a Retrieve UE Context Request message to the last serving gNB based on an Inactive Radio Network Temporary Identity (I-RNTI). The Retrieve UE Context Request message includes information about a Downlink (DL) Transport Network Layer (TNL) address associated with the MT-SDT. The receiving gNB receives DL data associated with the MT-SDT from the last serving gNB based on the DL TNL address, and transmits the DL data to the UE.

A client-initiated low-latency network edge spectrum-as-a-service controller is described herein. A method as described herein can include transmitting, by a system comprising a processor to a first spectrum access system, a request for first access rights to a first spectrum band, wherein the first spectrum band is wholly contained within a second spectrum band for which the first spectrum access system is granted second access rights from a second spectrum access system, distinct from the first spectrum access system; obtaining, by the system, the first access rights to the first spectrum band from the first spectrum access system in response to the request; and, in response to obtaining the first access rights, initiating, by the system via the first spectrum band, a point-to-point communication link between the system and a user equipment.
