摘要： A reference signal sending or receiving method and system, a terminal device, and an access network device are provided. The method includes: sending, by a first device, first control information to a second device, where the first control information is used to indicate a first resource used by the first device to send a reference signal; and sending, by the first device, the reference signal to the second device on the first resource. A transmission resource of the reference signal is no longer fixed, and a quantity of transmission resources, locations of the transmission resources, or the like may be determined based on factors such as a speed of the terminal device. For example, when the speed is low, a relatively small quantity of resources may be configured for sending the reference signal. In addition, the transmission resource of the reference signal is indicated by the first control information, so as to improve flexibility of sending the reference signal.

摘要： This application discloses a data packet transmission method and a terminal, where the method includes: determining, by a terminal, a transmission resource utilization threshold, where the transmission resource utilization threshold indicates maximum transmission resource utilization for transmitting a to-be-transmitted data packet by using a transmission resource in a resource pool in a preset time period, and the transmission resource utilization threshold is determined by resource utilization of the transmission resource in the resource pool; selecting, by the terminal, a target transmission resource in a first time period from the resource pool based on the transmission resource utilization threshold, so that transmission resource utilization of the transmission resource in the resource pool used by the terminal in a second time period is less than or equal to the transmission resource utilization threshold, where the second time period includes the first time period, and a time length of the first time period is greater than that of a transmission period of the to-be-transmitted data packet; and sending, by the terminal, the to-be-transmitted data packet on the target transmission resource. According to the method, an operation procedure in which the terminal determines the target transmission resource in a congestion control mechanism is simplified.

摘要： Embodiments of the present invention provide a resource configuration method and an apparatus. User equipment includes a receiving module and a processing module, where the receiving module is configured to receive a broadcast message sent by a control node and including at least one first resource pool, where the control node is a base station serving the UE or a group head UE of a group to which the UE belongs; and the processing module is configured to receive a device to device D2D service or send a D2D service by using a resource in the at least one first resource pool. Therefore, a problem of configuration of a resource pool for a UE in an idle state can be resolved, so that the UE in the idle state can acquire a sending resource pool or a receiving resource pool without connecting to a control node, which not only can reduce power consumption of the UE but also can reduce load on a to-be-connected base station.

摘要： A method and system for including a base station that configures a first user equipment (UE) that is in a radio resource control connected state with the base station. The UE is configured to be a synchronization source and transmit a first device-to-device synchronization signal (D2DSS) by using a synchronization resource that comprises a time resource, a frequency resource or a time and frequency resource. The base station instructs the first UE to transmit the first D2DSS using the synchronization resource. The base station signals the UE to configure the UE separately from the signal to transmit the D2DSS, and both of the signals are performed with radio resource control signaling from the base station to the UE.
