Resource request method, resource allocation method, devices, and mediums

A resource request method, applied to a remote user equipment, the method comprising:

• receiving information about a scheduling request (SR) resource configured by a network device;
• sending a second SR on the SR resource in a case that an uplink resource of the remote user equipment is insufficient to send a second buffer status report (BSR) and/or a third BSR, the second SR being 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 second BSR being used for requesting the network device to allocate a first resource, the third BSR being used for requesting the network device to allocate a second resource, the first resource being a resource used for data transmission from the remote user equipment to a relay user equipment, and the second resource being a resource used for data transmission from the relay user equipment to the network device;
• and
• receiving information about the resource used for sending the second BSR and the third BSR sent by the network device.

A resource allocation method, applied to a network device, the method comprising:

• sending information about a scheduling request (SR) resource to a remote user equipment;
• receiving a first SR or a second SR sent by the remote user equipment on the SR resource;
• wherein the first SR is used for requesting the network device to allocate a resource used for sending a first buffer status report (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 SR is used for requesting the network device to allocate a resource used for sending a second buffer status report (BSR) and a third BSR to the remote user equipment, the second BSR is used for requesting the network device to allocate a first resource, the third BSR is used for requesting the network device to allocate a second resource, 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;
• in a case where a first SR sent by the remote user equipment on the SR resource is received, allocating, according to the first SR, the resource used for sending the first BSR;
• and sending information about the resource used for sending the first BSR to the remote user equipment;
• in a case where a second SR sent by the remote user equipment on the SR resource is received, allocating, according to the second SR, the resource used for sending the second BSR and the third BSR;
• and sending information about the resource used for sending the second BSR and the third BSR to the remote user equipment.
