A resource request method, performed by a remote user equipment, wherein the method comprises: receiving information about a scheduling request, SR, resource configured by a network device; sending (S104, S204) a SR on the SR resource in a case that an uplink resource of the remote user equipment is insufficient to send a buffer status report, BSR, the SR being used for requesting the network device to allocate a resource used for sending the BSR to the remote user equipment; and receiving information about the resource used for sending the BSR sent by the network device; wherein the BSR comprises a first BSR, or the BSR comprises at least one of a second BSR and a third BSR; the SR comprises a first SR or a second SR; the first SR is used for requesting the network device to allocate a resource used for sending the first BSR to the remote user equipment, the second SR is used for requesting the network device to allocate a resource used for sending the second BSR and the third BSR to the remote user equipment, the first BSR is used for requesting the network device to allocate a first resource and a second resource, the second BSR is used for requesting the network device to allocate a first resource, and the third BSR is used for requesting the network device to allocate a second resource; and the first resource is a resource used for data transmission from the remote user equipment to a relay user equipment, and the second resource is a resource used for data transmission from the relay user equipment to the network device; characterized in that the method further comprises: in a case that the remote user equipment meets a condition for canceling SRs, performing at least one of: canceling sending of all pending SRs; and stopping an SR prohibit timer; wherein the condition for canceling SRs comprises at least one of: reselecting a relay user equipment, stopping a relay operation, or switching from a relay communication mode to a non-relay communication mode. receiving information about a scheduling request, SR, resource configured by a network device; sending (S104, S204) a SR on the SR resource in a case that an uplink resource of the remote user equipment is insufficient to send a buffer status report, BSR, the SR being used for requesting the network device to allocate a resource used for sending the BSR to the remote user equipment; and receiving information about the resource used for sending the BSR sent by the network device; wherein the BSR comprises a first BSR, or the BSR comprises at least one of a second BSR and a third BSR; the SR comprises a first SR or a second SR; the first SR is used for requesting the network device to allocate a resource used for sending the first BSR to the remote user equipment, the second SR is used for requesting the network device to allocate a resource used for sending the second BSR and the third BSR to the remote user equipment, the first BSR is used for requesting the network device to allocate a first resource and a second resource, the second BSR is used for requesting the network device to allocate a first resource, and the third BSR is used for requesting the network device to allocate a second resource; and the first resource is a resource used for data transmission from the remote user equipment to a relay user equipment, and the second resource is a resource used for data transmission from the relay user equipment to the network device; characterized in that the method further comprises: in a case that the remote user equipment meets a condition for canceling SRs, performing at least one of: canceling sending of all pending SRs; and stopping an SR prohibit timer; wherein the condition for canceling SRs comprises at least one of: reselecting a relay user equipment, stopping a relay operation, or switching from a relay communication mode to a non-relay communication mode. in a case that the remote user equipment meets a condition for canceling SRs, performing at least one of: canceling sending of all pending SRs; and stopping an SR prohibit timer; wherein the condition for canceling SRs comprises at least one of: reselecting a relay user equipment, stopping a relay operation, or switching from a relay communication mode to a non-relay communication mode.
