Abstract: This application may be applied to an internet of vehicles, for example, V2X, LTE-V, and V2V. A first terminal device obtains a first time-frequency resource, where the first time-frequency resource is used to send sidelink control information and data. The first terminal device sends, on the first time-frequency resource, a sidelink reference signal, the sidelink control information, and the data to a second terminal device, where the sidelink reference signal is used to determine a channel status of a sidelink between the first terminal device and the second terminal device. According to the sidelink reference signal transmission method provided in this application, the sidelink reference signal is carried on the time-frequency resource used to send the sidelink control information and/or the data, and is sent together with the sidelink control information and/or the data.

Abstract: This application provides a sidelink control information sending method and a communications device. A method for sending unicast or multicast sidelink control information in V2X communication is provided. In the method, sidelink control information is divided into two parts. The first part includes resource indication information for transmitting sidelink data, and is scrambled by using a common sequence. The second part is sidelink control information other than the first part of sidelink control information, and is scrambled by using an identifier of a target communications device or a group identifier of a group to which the target communications device belongs. The target communications device can descramble the first part and the second part, and receive sidelink data in the V2X communication. Another communications device can descramble the first part obtain resource information, and can learn of resource occupation and reservation information when performing autonomous resource selection beyond network coverage.

Abstract: Example response information sending and receiving methods and apparatus are described. One example sending method includes receiving first indication information by a first communications device from a network device, where the first indication information is used to indicate a first resource for transmitting first data. The first communications device sends the first data to a second communications device on the first resource. The first communications device receives second indication information from the network device, where the second indication information is used to indicate a second resource for transmitting response information of the first data. The second source and the first resource do not include a same resource. The first communications device receives the response information of the first data from the second communications device on the second resource.

Abstract: Example HARQ-based transmission methods and apparatus are provided, to meet transmission requirements of different services. In one example method, a network device receives a QoS parameter that is of a service corresponding to a service request and that is delivered by a core network device. The network device determines, based on the QoS parameter of the service, a HARQ configuration parameter corresponding to the service, and notifies the HARQ configuration parameter to the terminal device. Therefore, when different services are transmitted between the network device and the terminal device, different HARQ configuration parameters are configured for different services, and data transmission and retransmission of a service are performed based on a configured HARQ configuration parameter, so that transmission requirements of different services can be met.

Abstract: The present disclosure discloses example power control methods and apparatuses. One example method includes determining a transmit power of a control channel and a first data subchannel, where the control channel and the first data subchannel completely overlap in time domain and do not overlap in frequency domain. A transmit power of a second data subchannel is determined to be the same as the transmit power of the control channel and the first data subchannel, where the second data subchannel and the control channel overlap in frequency domain and do not overlap in time domain. The control channel and the first data subchannel are sent to a second terminal apparatus at the transmit power of the control channel and the first data subchannel. The second data subchannel is sent to the second terminal apparatus at the transmit power of the control channel and the first data subchannel.

Abstract: An exemplary embodiment provides a transmission resource determining method and apparatus. A first terminal device obtains a slot format corresponding to at least one other terminal device in a first slot, where the slot format includes a first slot format and/or a second slot format; symbols used for sending information and receiving information in the first slot format are inconsistent with those in the second slot format. The first terminal device determines, based on the slot format corresponding to the at least one other terminal device in the first slot, a slot format corresponding to the first terminal device in the first slot. This may be applied to an Internet of Vehicles, for example, V2X, LTE-V, and V2V.

Abstract: Embodiments provide an SDN, an SDN configuration method, an SDN-based data transmission method, and a network controller. A data packet combination function and a data packet split function are separately configured on nodes in the SDN. Therefore, when data packets of a first service are received, multiple small data packets of the first service may be combined into one large data packet. In comparison with transmission of the multiple small data packets, transmission efficiency of the SDN can be improved by transmitting the combined data packet.
