Abstract: The present disclosure relates to methods for indicating a direct current subcarrier and communication apparatuses. In one example method, a second communication apparatus may explicitly or implicitly indicate a location of a first direct current subcarrier and a location of a second direct current subcarrier to a first communication apparatus. The first direct current subcarrier is a direct current subcarrier corresponding to a transmit frequency used by the second communication apparatus. The second direct current subcarrier is a direct current subcarrier corresponding to a receive frequency used by the first communication apparatus.

Abstract: Embodiments of this disclosure provide a power adjustment method, apparatus, and system. A first access network device may obtain a power back-off value at a first moment, and compare the power back-off value at the first moment with a power back-off value at a second moment. The second moment is earlier than the first moment. When a difference between the power back-off value at the second moment and the power back-off value at the first moment is greater than or equal to a first threshold, the first access network device adjusts an output power based on the power back-off value at the first moment.

Abstract: This application provides an example timing advance update method, an example terminal, and an example base station. One example method includes receiving, by a terminal, an updated timing advance TA value and a beam cell identity of a beam cell in which the terminal is located that are sent by a base station. The example method also includes obtaining, by the terminal, corresponding TA compensation information based on the beam cell identity. The example method further includes performing, by the terminal, TA compensation in a TA update period based on the updated TA value and the TA compensation information. The example method also includes sending, by the terminal, uplink data by using a TA value obtained after TA compensation is performed.
