Claim 3:
4. A terminal device, comprising:
a processor, configured to acquire a target Physical Random Access Channel (PRACH) resource set, wherein the target PRACH resource set comprises at least one resource set of a first PRACH resource set and a second PRACH resource set, and at least one resource of the first PRACH resource set and at least one resource of the second PRACH resource set are different; wherein
the processor is further configured to determine a target PRACH resource from the target PRACH resource set, wherein the target PRACH resource is used for PRACH sending in a random access procedure;
wherein when the target PRACH resource set comprises the second PRACH resource set, the terminal device further comprises:
a communication unit, configured to receive first indication information sent by a network device, wherein the first indication information is used for determining a second PRACH resource set configuration within a first time period;
the processing unit is specifically configured to:
determine a second PRACH resource set within the first time period according to the second PRACH resource set configuration within the first time period;

wherein the first time period is one transmission opportunity after the network device preempts a channel following a principle of Listen Before Talk (LBT).
