Communication method and apparatus for resource configuration

A communication apparatus, comprising:

• a processor, configured to obtain transmission resource configurations, wherein the transmission resource configurations comprise a first configuration and a second configuration, the first configuration indicates that a start time domain resource is a downlink time domain resource and/or an end time domain resource is an uplink time domain resource in one configuration period, and the second configuration indicates that a start time domain resource is an uplink time domain resource and/or an end time domain resource is a downlink time domain resource in one configuration period;
• and
• determine, according to a specified rule, one or more of the following:
• whether to send an uplink signal on a third time domain resource in a reference configuration, or whether to receive a downlink signal on a fourth time domain resource in the reference configuration, wherein the reference configuration is at least one of the first configuration or the second configuration, wherein the specified rule comprises:
• when the third time domain resource is a downlink time domain resource at a resource position of the uplink signal, the uplink signal is not sent on the third time domain resource;
• and
• when the fourth time domain resource is an uplink time domain resource at the resource position of the downlink signal, the downlink signal is not received on the fourth time domain resource.
