Description

CROSS-REFERENCE TO RELATED APPLICATION(S) This application is a National Stage of International Application No. PCT/CN 2023/125051, field Oct. 17, 2023, which claims priority to Chinese patent application No. 202211272269.6, filed Oct. 18, 2022, both of which are incorporated by reference herein. TECHNICAL FIELD This disclosure relates to the field of communication technology, in particular to a communication method and a related apparatus. BACKGROUND In a time division duplexing (TDD) system, a terminal device and a network device perform uplink (UL) communication in a UL slot and perform downlink (DL) communication in a DL slot. If the terminal device needs to perform DL communication in the UL slot, the terminal device needs to wait for the DL slot to perform DL communication, which will easily lead to transmission delay, thereby failing to meet the needs of low-latency services or high-speed services. At present, in order to solve the above problem, sub-band full duplex (SBFD) is introduced in the TDD system, that is, a frequency-domain resource corresponding to the same slot is divided into a UL frequency-domain resource and a DL frequency-domain resource. For example, a certain UL slot is taken as an example, the UL slot corresponds to a UL frequency-domain resource and a DL frequency-domain resource, and the UL frequency-domain resource does not overlap in a frequency domain with the DL frequency-domain resource. As such, when the terminal device needs to perform UL communication in the UL slot, the terminal device can perform UL communication in the UL frequency-domain resource corresponding to the UL slot, and when the terminal device needs to perform DL communication in the UL slot, the terminal device can perform DL communication on the DL frequency-domain resource corresponding to the UL slot without waiting. For another example, a certain DL slot is taken as an example. If a frequency-domain resource corresponding to the DL slot is not divided into a UL frequency-domain resource and a DL frequency-domain resource, the terminal device can only perform DL communication but not perform UL communication in the DL slot. However, after the introduction of the SBFD, frequency-domain resources corresponding to some slots may be divided into a UL frequency-domain resource and a DL frequency-domain resource, while frequency-domain resources corresponding to some other slots may not be divided into a UL frequency-domain resource and a DL frequency-domain resource. Therefore, how to perform repetition is a problem to be solved. SUMMARY In a first aspect, embodiments of the present disclosure provide a communication method. The method includes the following. Frequency-domain resource indication information is received, where the frequency-domain resource indication information indicates a frequency-domain resource location for channel transmission.

At least one channel transmission is performed based on the frequency-domain resource for channel transmission in the frequency-domain resources respectively corresponding to the at least one time-domain resource. In a second aspect, embodiments of the present disclosure provide a communication method. The method includes the following.
