Abstract: Embodiments of the present disclosure provide a resource scheduling method, apparatus, and system. The embodiments of the present disclosure relate to the field of communications technologies and are used to resolve a problem of resource scheduling in Device-to-Device (D2D) communication. The method includes: sending, by a first node, first control signaling to a second node, where the first control signaling includes information about a resource for second control signaling transmission and information about a resource for data transmission; and receiving, by the second node, the first control signaling sent by the first node, and sending second control signaling to a third node by using the resource for the second control signaling transmission, and sending data to the third node by using the resource for the data transmission. The resource scheduling method, apparatus, and system can be applied to a data transmission device requiring relatively high delay performance.

Abstract: Embodiments of the present disclosure provide an information transmission method, including: determining, by a user equipment (UE), first speed information of the UE; determining, by the UE, a transmission manner of control information based on the first speed information; and sending, by the UE, the control information in the transmission manner over a first link. In the embodiments of the present disclosure, the UE may determine the transmission manner of the control information based on the first speed information. When the UE is high speed UE, an appropriate transmission manner can be selected for the high speed UE, thereby meeting a transmission requirement of the high speed UE and ensuring a transmission success rate.

Abstract: The present disclosure relates to a method for determining a first-link transmit power. In one example method, a user equipment (UE) obtains transmit power indication information of a first link. The UE determines a first transmit power of control information and a second transmit power of data based on the transmit power indication information. The UE sends the control information at the first transmit power, and the data at the second transmit power. The control information and the data are sent on the first link in a same subframe.

Abstract: Embodiments of the present invention provide a resource reuse method and apparatus, and pertain to the field of communications technologies. The method includes: sending a declaration message on a first resource, so that after receiving the declaration message, a terminal of a low service priority releases an occupied second resource according to the declaration message; and obtaining the second resource released by the terminal of a low service priority. According to the present invention, a declaration message is sent on a first resource, so that after receiving the declaration message, a terminal of a low service priority releases an occupied second resource according to the declaration message, so as to obtain the second resource released by the terminal of a low service priority. Because a terminal of a high service priority may obtain a resource without waiting, a delay of resource reuse is shortened, and resource utilization efficiency is improved.

Abstract: This application provides a control information sending method and a communication apparatus. According to the method, a terminal may determine, based on first information, a resource occupied by transmission according to a first communication protocol; determine, based on the resource occupied by transmission according to the first communication protocol, that a first resource is an available resource; and transmit control information on the first resource according to a second communication protocol. This can avoid control information transmission according to the second communication protocol by using the resource occupied by transmission according to the first communication protocol, thereby helping avoid a resource conflict between transmission according to the first communication protocol and transmission according to the second communication protocol.
