selecting, by a higher layer of the first terminal device, a sidelink transmission resource randomly from the shared resource set.
8 . A terminal device, comprising a processor and a memory for storing a computer program executable on the processor, wherein the processor is configured to, when executing the computer program, cause the terminal device to:
select a sidelink transmission resource based on a shared resource set in a resource selection or resource reselection process,
wherein said selecting the sidelink transmission resource based on the shared resource set comprises:
selecting the sidelink transmission resource from resources other than the shared resource set,
wherein when sidelink transmission resources resources included in the shared resource set overlap all or part of sidelink transmission resources for retransmission of a transmitted transport block as indicated in a sidelink grant for the terminal device in a time domain, the terminal device is triggered to perform resource selection or resource reselection.
9 . The terminal device according to claim 8 , wherein the shared resource set is determined based on first indication signaling transmitted by a second terminal device to the terminal device.
10 . The terminal device according to claim 8 , wherein said selecting the sidelink transmission resource based on the shared resource set comprises:
selecting the sidelink transmission resource from the shared resource set based on a channel detection result.
11 . The terminal device according to claim 8 , wherein said selecting the sidelink transmission resource based on the shared resource set comprises:
selecting the sidelink transmission resource randomly from the shared resource set.
12 . The terminal device according to claim 10 , wherein the processor, when executing the computer program, further causes the terminal device to:
determine an intersection of a second resource set and the shared resource set as a first resource set, the second resource set being a set of resources determined by the terminal device based on the channel detection result; and
at least one of resources in the first resource set being used for data transmission.
13 . The terminal device according to claim 8 , wherein the processor, when executing the computer program, further causes the terminal device to:
determine a seventh resource set in a sixth resource set that partially overlaps or completely overlaps resources in the shared resource set, the sixth resource set being a set of resources determined by the terminal device based on the channel detection result; and
transmit, by a physical layer of the terminal device, resources in the sixth resource set, other than the seventh resource set, to a higher layer, at least one of the resources being used for data transmission.
14 . The terminal device according to claim 11 , wherein the processor, when executing the computer program, further causes the terminal device to:
selecting, by a higher layer of the terminal device, a sidelink transmission resource randomly from the shared resource set.
15 . A chip, comprising: a processor configured to revoke and execute a computer program from a memory, to enable a device provided with the chip to perform a resource selection method comprising:
selecting, by a first terminal device, a sidelink transmission resource based on a shared resource set in a resource selection or resource reselection process,
wherein said selecting, by the first terminal device, the sidelink transmission resource based on the shared resource set comprises:
selecting, by the first terminal device, the sidelink transmission resource from resources other than the shared resource set,
wherein when sidelink transmission resources resources included in the shared resource set overlap all or part of sidelink transmission resources for retransmission of a transmitted transport block as indicated in a sidelink grant for the terminal device in a time domain, the terminal device is triggered to perform resource selection or resource reselection.
16 . A non-transitory storage medium, storing an executable program which, when executed by a processor, implements the resource selection method according to claim 1 .
17 . The chip according to claim 15 , wherein the shared resource set is determined based on first indication signaling transmitted by a second terminal device to the first terminal device.
