Method, device and computer readable medium for resource selection
Embodiments of the present disclosure relate to methods, devices and computer readable media for resource selection. In example embodiments, a method for resource selection includes selecting, at a first terminal device, a first resource for transmitting a first packet from a resource pool. The method further includes determining a second resource selected from the resource pool by a second terminal device for transmitting a second packet. The method further includes determining whether a first transmission priority associated with the first packet is lower than a second transmission priority associated with the second packet. The method further includes in response to determining that the first transmission priority is lower than the second transmission priority, selecting an available resource from the resource pool to transmit the first packet.
1. A method performed by a first terminal, comprising:
transmitting a first information about a first resource for transmitting a first packet from a resource pool;
in response to the first resource colliding with a second resource from the resource pool for transmitting a second packet indicated by a received second information, determining whether a first transmission priority associated with the first packet is lower than a second transmission priority associated with the second packet; and
in response to determining that the first transmission priority is lower than the second transmission priority, selecting an available resource from the resource pool to transmit the first packet.
2. The method of claim 1 , further comprising:
in response to determining that the first transmission priority is higher than the second transmission priority, transmitting the first packet using the first resource.
3. The method of claim 1 , wherein selecting the available resource from the resource pool comprises:
selecting the available resource from the resource pool to replace the first resource.
4. The method of claim 1 , wherein determining whether the first transmission priority is lower than the second transmission priority comprises:
determining whether the first transmission priority is lower than the second transmission priority, based on attribute information associated with the first and second packets, the attribute information including at least one of:
packet priorities of the first and second packets, a packet priority of the first packet indicating a priority configured by a higher layer;
remaining selection windows for the first and second packets, a remaining selection window for the first packet indicating a time period remained for the first terminal device to transmit the first packet;
reliabilities of the first and second packets;
latencies of the first and second packets; and
minimum communication ranges of the first and second packets.
5. The method of claim 4 , wherein determining whether the first transmission priority is lower than the second transmission priority based on the attribute information comprises:
comparing the packet priority of the first packet and a packet priority of the second packet; and
in response to the packet priority of the first packet being lower than the packet priority of the second packet, determining that the first transmission priority is lower than the second transmission priority.
6. An apparatus, comprising:
a transmitter;
a receiver; and
one or more processors coupled to the transmitter and receiver, and configured to cause the apparatus to:
transmit a first information about a first resource for transmitting a first packet from a resource pool;
in response to the first resource colliding with a second resource from the resource pool for transmitting a second packet indicated by a received second information, determine whether a first transmission priority associated with the first packet is lower than a second transmission priority associated with the second packet; and
in response to determining that the first transmission priority is lower than the second transmission priority, select an available resource from the resource pool to transmit the first packet.
7. The apparatus of claim 6 , wherein the one or more processors are further configured to, cause the apparatus to:
in response to determining that the first transmission priority is higher than the second transmission priority, transmitting the first packet using the first resource.
8. The apparatus of claim 6 , wherein the one or more processors are further configured to cause the apparatus to:
select the available resource from the resource pool to replace the first resource.
9. A computer readable medium having instructions stored thereon, the instructions, when executed on at least one processor, causing the at least one processor to carry out a method, the method comprising:
transmitting a first information about a first resource for transmitting a first packet from a resource pool;
in response to the first resource colliding with a second resource from the resource pool for transmitting a second packet indicated by a received second information, determining whether a first transmission priority associated with the first packet is lower than a second transmission priority associated with the second packet; and
in response to determining that the first transmission priority is lower than the second transmission priority, selecting an available resource from the resource pool to transmit the first packet.
