AI Technical Summary
Technical Problem
When random access is performed on subband non-overlapping full-duplex (SBFD) symbols/slots, uplink channel transmission may fall into downlink frequency domain resources, affecting transmission performance.
Method used
By using frequency hopping technology in the SBFD time unit, uplink signals are sent on the third and fourth frequency domain resources to determine the second frequency domain resources, ensuring that uplink channel transmission falls within the uplink frequency domain resources. Frequency hopping between or within time slots is used to improve flexibility.
Benefits of technology
This improves the uplink transmission performance and the success rate of random access for terminal devices in the SBFD time unit.

Abstract
The present application relates to a communication method and a communication apparatus. The method comprises: according to a first frequency domain resource, determining a second frequency domain resource, the first frequency domain resource being a frequency domain resource where a first uplink BWP overlaps a first uplink sub-band, the second frequency domain resource comprising a third frequency domain resource and a fourth frequency domain resource, and the third frequency domain resource and the fourth frequency domain resource being used for transmission of a first signal; and, in a first SBFD time unit, transmitting the first signal on the third frequency domain resource and the fourth frequency domain resource by means of frequency hopping, the first signal being carried on a PUSCH or a PUCCH.
