1. A resource request method, comprising:
receiving, by a relay device, a first target device message sent by a target device, wherein the first target device message is used to trigger the relay device to request a network side node to allocate a data transmission resource to the target device;
sending, by the relay device, a first relay device message to the network side node according to the first target device message, wherein the first relay device message is used to trigger the network side node to send first grant information to the target device, and the first grant information comprises the data transmission resource allocated by the network side node to the target device, wherein the data transmission resource is used by the target device to transmit to-be-transmitted data;
wherein, before the receiving, by the relay device, the first target device message sent by the target device: receiving, by the relay device, a second target device message sent by the target device, the second target device message being used to trigger the relay device to request the network side node to configure a D2D sidelink buffer status report resource for the target device; and sending, by the relay device, a second relay device message to the network side node according to the second target device message, the second relay device message being used to trigger the network side node to send second grant information to the target device, the second grant information comprising the D2D sidelink buffer status report resource configured by the network side node for the target device, wherein, the D2D sidelink buffer status report resource is used by the target device to send the first target device message to the relay device.
