Abstract: This application provides a communication method and a terminal device. The communication method may include determining, by user equipment (UE), a candidate resource set on a first carrier, where the first carrier is a carrier on which a resource is currently to be selected, and the first carrier is used to transmit first data. The method may also include selecting, by the UE, a resource on the first carrier from the candidate resource set based on a preset condition, where the preset condition is determined based on resources selected by the UE on other carriers and one or more of the following: a quantity of transmit chains of the UE, a transmit power of the UE, a quantity of resource blocks occupied by the UE, a frequency domain spacing between a plurality of carriers or a plurality of frequency domain resources occupied by the UE, a carrier switching time of the UE, and a half-duplex limitation to the UE, the other carriers indicate all carriers on which the UE has currently selected a resource, and the other carriers are used to transmit second data. The method may also include sending, by the UE, the first data on the resource selected on the first carrier.

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 provide a method for releasing a semi-persistent scheduling resource and a device. The method can be used in V2X communication. The method may include receiving, by a base station, service information sent by user equipment UE. The service information may include first service information of first service data. The method may further include determining, by the base station based on the first service information, semi-persistent scheduling SPS information corresponding to the first service data; and sending, by the base station, downlink control information DCI to the UE. The DCI may include the SPS information, and may be used to instruct the UE to activate the new SPS resource and release a target SPS resource. The target SPS resource may include an SPS resource corresponding to second service data that has been transmitted. This can reduce signaling overheads of the DCI.

Abstract: A communication method and a communications apparatus are disclosed. In the communication method, a first terminal obtains a resource period parameter, where the resource period parameter is sent by a network-side device or preconfigured by the first terminal. The resource period parameter includes a period duration of each of at least one resource. The first terminal determines a start time unit of a resource period, and the first terminal sends communication data according to the start time unit of the resource period and the resource period parameter.

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; and a terminal sends communication data based on the group of values of the at least two groups of values of the transmission parameter set. The present invention can adapt to different system statuses and service requirements, thereby improving transmission performance.
