1. A method in a network device comprising:
transmitting a Random Access Channel (RACH) Occasion configuration to a terminal device, the RACH Occasion configuration comprising:
a first time resource indication identifying at least a first set of time resources in which the terminal device is allowed to transmit a RACH preamble according to a first random access procedure,
a first frequency resource indication identifying at least a first set of frequency resources in which the terminal device is allowed to transmit the RACH preamble according to the first random access procedure,
a second time resource indication identifying at least a second set of time resources in which the terminal device is allowed to transmit a RACH preamble according to a second random access procedure, and
a second frequency resource indication identifying at least a second set of frequency resources in which the terminal device is allowed to transmit the RACH preamble according to the second random access procedure, wherein the second time resource indication and the second frequency resource indication further indicate an association period; and
receiving a RACH preamble which is transmitted from the terminal device according to the RACH Occasion configuration, wherein the first random access procedure is a four-step random access procedure and the second random access procedure is a two-step random access procedure, and wherein in the two-step random access procedure, the terminal device transmits message A including the RACH preamble and Physical Uplink Shared Channel (PUSCH) data.
