    Abstract: Embodiments provide a data exchange method, a terminal device, and a network device. In accordance with the disclosure, a terminal device can obtain resource information for communicating with another terminal device. The resource information can indicate a time-frequency resource and an antenna port corresponding to an antenna polarization direction. The terminal device can then send scheduling information and data information to the another terminal device using the time-frequency resource and the antenna polarization direction. Time-frequency resources and/or antenna polarization directions used by any two terminal devices to send scheduling information and data information to other terminal devices can be different. In this way, terminal devices using different transmit antenna ports can use a same time-frequency resource, and an optional dimension of resource information is increased, thereby increasing an overall system communication capacity.

    Abstract: A communication method, a network side device, and a terminal are provided. In the method, a network side device selects one group of values from at least two preset groups of values for a transmission parameter set. The network side device sends the selected group of values. A terminal sends communication data based on the group of values of the at least two groups of values of the transmission parameter set.

    Abstract: A data sending method, a terminal device, an access network device, and a system are provided. The method includes: obtaining, by a terminal device, a sending period of first data; obtaining, by the terminal device, configuration information of a first resource; determining, a second resource based on the configuration information of the first resource and a sending period of the first data; and selecting, by the terminal device, a resource other than the second resource to send the first data. When selecting a resource used for V2X communications data or D2D communications data, the terminal device excludes the second resource that cannot be used for the V2X communications data or the D2D communications data, so as to avoid a conflict between the second resource and the resource selected by the terminal device for sending the first data, and improve reliability and security of D2D communication and V2X communication.

    Abstract: Embodiments of the present invention relate to a communication method and a terminal. The method includes: receiving, by a first terminal, first information on a first channel, where the first information carries a first sequence of at least one second terminal, the first terminal supports a first transmission technology, the second terminal supports a second transmission technology, and the first sequence of the second terminal is used to indicate that the first channel is used by a terminal that supports the second transmission technology; determining, by the first terminal, first indication information based on the first sequence; and sending, by the first terminal, the first indication information on the first channel. According to the communication method provided in the embodiments of the present invention, terminals that support different transmission technologies can better coexist on a plurality of shared channels, and interference between the different transmission technologies can be avoided.
