Information exchange method and apparatus in uwb system

An information exchange method in an ultra-wideband system, comprising:

• receiving, by a communication apparatus, a control message, wherein the control message indicates a frequency band overlapping rate between adjacent channels in a channel set used for frequency band stitching;
• and
• determining, by the communication apparatus based on the frequency band overlapping rate indicated by the control message, whether the channel set is in an in-sequence channel order or an out-of-sequence channel order, wherein
• when the frequency band overlapping rate belongs to a preset first overlapping rate set, the channel set is in the in-sequence channel order;
• or when the frequency band overlapping rate belongs to a preset second overlapping rate set, the channel set is in the out-of-sequence channel order;
• and the in-sequence channel order and the out-of-sequence channel order are distinguished based on whether different channels in the channel set are in ascending order or descending order of center frequencies.

A communication apparatus, comprising:

• one or more processors, wherein the one or more processors are coupled to one or more memories;
• and
• the one or more memories are configured to store a computer program, and the one or more processors are configured to execute the computer program stored in the one or more memories, to configure the communication apparatus to:
• determine a frequency band overlapping rate between adjacent channels in a channel set used for frequency band stitching;
• and
• send a control message, wherein the control message indicates the frequency band overlapping rate;
• and
• when the frequency band overlapping rate belongs to a preset first overlapping rate set, the channel set is in an in-sequence channel order;
• or when the frequency band overlapping rate belongs to a preset second overlapping rate set, the channel set is in an out-of-sequence channel order;
• and the in-sequence channel order and the out-of-sequence channel order are distinguished based on whether different channels in the channel set are in ascending order or descending order of center frequencies.
