A device for secure transmission of vehicle data over vehicle datalinks that may be shared with passenger devices and are connected to a publicly shared network is provided. The device comprises a processor embedded within a portion of an Ethernet cable for a vehicle. A plurality of applications resides in the processor and comprises a VPN application, and a VPN address and certificate update application. A first Ethernet transceiver communicates with the processor through the VPN application and also communicates with onboard electronic equipment. A second Ethernet transceiver communicates with the processor through the VPN application and also communicates with an external datalink. The VPN application automatically establishes a VPN when the datalink is available, provides an authentication certificate to verify that the device is a correct and legitimate node, and verifies a VPN hosting certification to determine whether the device is communicating with a correct and legitimate external facility.

The base station may selectively apply one of a first time period having a first guard period (GP) and a second time period having a second GP to time-division duplex communication with a terminal. Further, the base station may notify the terminal of information related to a timing of selectively applying one of the first time period and the second time period, and transmit a predetermined signal in the first guard period.

The application provide an access method, including: sending, to an access point, a first frame that carries uplink transmission requirement information; and if a second frame that carries information about an uplink transmission resource is received from the access point within agreed time period, sending uplink multi-user transmission data to the access point, where the uplink multi-user transmission data is transmitted on the uplink transmission resource; or if the second frame is not received within an agreed time period, accessing, by a station, a channel in a contention access manner that is based on carrier sense CSMA/CA.

A communication method and system for converging a 5.sup.th generation (5G) communication system for supporting higher data rates beyond a 4.sup.th generation (4G) system with a technology for Internet of things (IoT) are provided. The communication method and system may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method performed by a terminal for handling scheduling request (SR) cancellation in a wireless communication system is provided. The method comprises identifying that at least one first SR is triggered, identifying whether each of the at least one first SR is triggered for beam failure recovery (BFR) of a secondary cell (SCell), and determining whether to cancel each of the at least one SR based on the identification.

A wireless communication system is provided. The wireless communication system includes a first cell configured to communicate with a second cell and a terminal. The first cell includes a processor configured to control the first cell to: select one of a plurality of scheduling modes related to rate matching of physical downlink shared channels (PDSCHs) based on control information exchanged with the second cell; and transmit a first PDSCH to the terminal according to the selected scheduling mode while the second cell transmits a second PDSCH to the terminal according to the selected mode. The terminal is configured to perform processing on the first PDSCH and the second PDSCH based on the selected scheduling mode.

For multiplexing control information in a physical uplink data channel, a user equipment (UE) includes receiving a configuration for a first set of values and receiving a downlink control information (DCI) format scheduling a transmission of a physical uplink shared data channel (PUSCH) over a set of resource elements (REs) and including a field providing an index. The method further includes determining a first value from the first set of values based on the index, determining a first subset of REs from the set of REs, for multiplexing first uplink control information (UCI), based on the first value, and transmitting the first UCI in the PUSCH.

The present disclosure relates to a mobile terminal, a system and respective methods. The user equipment receives plural PDCCHs from each of plural TRPs within a single TTI, and decodes plural DCIs respectively carried on the received plural PDCCHs from each of the plural TRPs. All of the decoded plural DCIs from each of the plural TRPs are respectively scheduling plural PDSCH receptions or plural PUSCH transmissions on different ones of the plural TRPs. And all of the plural PDSCH receptions or plural PUSCH transmission are scheduled such that one of the decoded plural DCIs from each of the plural TRPs is scheduling a same one PDSCH reception or a same one PUSCH transmission on a same one of the plural TRPs. The user equipment receives or transmits same data in the respectively scheduled plural PDSCH receptions from or PUSCH transmission to each of the plural TRPs.

A method for sending and receiving multi-carrier information in a communication system supporting a multi-carrier includes sending by a base station system information to the terminal via a broadcast message, the system information regarding multi-carriers that the base station is able to support; receiving a unicast message from the terminal, the unicast message including information related to carriers that the terminal is able to support or prefers in the multi-carrier list included in the system information; and sending multi-carrier allocation information including a primary carrier and a second carrier that the terminal will use, to the terminal via a unicast message.
