1. A random access response (RAR) method, wherein the method comprises:
receiving a first random access preamble from a first terminal device and a second random access preamble from a second terminal device, wherein the first terminal device and the second terminal device are separate devices; sending a first RAR to the first terminal device based on the first random access preamble, wherein the first RAR belongs to a first RAR group, and the first RAR is carried on a first physical downlink shared channel (PDSCH); and
sending a second RAR to the second terminal device based on the second random access preamble, wherein the second RAR belongs to a second RAR group, and the second RAR is carried on a second PDSCH, wherein the first random access preamble and the second random access preamble correspond to a same random access occasion, wherein the first PDSCH and the second PDSCH are a same PDSCH, and wherein the first RAR and the second RAR are separate RARs.
