Communication method and wireless apparatus

An apparatus, comprising:

• one or more processors, and
• a computer-readable storage medium storing program instructions, wherein, when executed by the one or more processors, the instructions cause the apparatus to:
• receive signaling on a first carrier;
• and
• determine M slot formats of N slots on a second carrier based on the received signaling, wherein N and M are positive integers, wherein M is greater than 1, wherein each of the M slot formats corresponds to a respective slot group in M slot groups, and wherein each of the M slot groups comprises more than one slot of the N slots that have a same slot format, and wherein:
• a quantity of the N slots on the second carrier is determined based on:
• a relationship between a length of a first slot on the first carrier and a length of a second slot on the second carrier, or
• a relationship between a subcarrier spacing (SCS) of the first carrier and a subcarrier spacing of the second carrier;
• and
• a start slot of the N slots on the second carrier is a slot on the second carrier that corresponds to a receiving moment at which the signaling is received on the first carrier.

• and
• send signaling on a first carrier, wherein the signaling comprises indication information of the M slot formats, and wherein:
• a quantity of the N slots on the second carrier is determined based on:
• a relationship between a length of a first slot on the first carrier and a length of a second slot on the second carrier, or
• a relationship between a subcarrier spacing (SCS) of the first carrier and a subcarrier spacing of the second carrier;
• and
• a start slot of the N slots on the second carrier is a slot on the second carrier that corresponds to a receiving moment at which the signaling is received on the first carrier.

A communication method, comprising:

• determining, by a network device, M slot formats of N slots on a second carrier, wherein N and M are positive integers, wherein M is greater than 1, wherein each of the M slot formats corresponds to a respective slot group in M slot groups, and wherein each of the M slot groups comprises more than one slot of the N slots that have a same slot format;
• and
• sending, by the network device, signaling on a first carrier, wherein the signaling comprises indication information of the M slot formats, and wherein:
• a quantity of the N slots on the second carrier is determined based on:
• a relationship between a length of a first slot on the first carrier and a length of a second slot on the second carrier, or
• a relationship between a subcarrier spacing (SCS) of the first carrier and a subcarrier spacing of the second carrier;
• and
• a start slot of the N slots on the second carrier is a slot on the second carrier that corresponds to a receiving moment at which the signaling is received on the first carrier.
