Claim of US Patent No. 10,798,709

1. A communication method, comprising:determining, by a terminal device, a first frequency-domain resource, wherein the first frequency-domain resource is an available resource preconfigured for supporting transmission of a first physical channel in a first target time unit by using a first Transmission Time Interval (TTI), and a time length of the first TTI is equal to a time length of the first target time unit;
determining, by the terminal device, a second frequency-domain resource, wherein the second frequency-domain resource is determined to transmit a second physical channel in a second target time unit by using a second TTI, the second TTI is not smaller than the first TTI, and the second target time unit at least partially overlaps with the first target time unit; and
determining, by the terminal device, a third frequency-domain resource, wherein the third frequency-domain resource comprises at least part of frequency-domain resources of the second frequency-domain resource, and the third frequency-domain resource is a maximum available frequency-domain resource for supporting transmission of the first physical channel in the first target time unit by using the first TTI;
determining, by the terminal device, a target frequency-domain resource from the third frequency-domain resource; and
utilizing, by the terminal device, the target frequency-domain resource to send the first physical channel to a network device or receive the first physical channel sent by a network device in the first target time unit by using the first TTI;
wherein the determining, by the terminal device, the target frequency-domain resource from the third frequency-domain resource comprises:
receiving first Downlink Control Information (DCI) sent by the network device, wherein the first DCI is configured to indicate a location of the target frequency-domain resource in the third frequency-domain resource; and
determining the target frequency-domain resource based on the DCI;
wherein the method further comprises:
continuously re-sequencing Physical Resource Blocks (PRBs) in the third frequency-domain resource,
wherein the first DCI is configured to indicate a re-sequencing number of the PRB corresponding to the target frequency-domain resource to indicate the location of the target frequency-domain resource in the third frequency-domain resource.
